Jannah, Erliyah Nurul
Gangguan kepribadian histerik atau yang biasa dikenal dengan gangguan kepribadian histrionik merupakan gangguan kepribadian dengan karakter emosi yang meluap-luap, termasuk keinginan berlebihan untuk mendapatkan pujian. Penderita gangguan kepribadian histerik mempunyai tingkah laku yang dramatik dan bereaksi terhadap sesuatu secara berlebihan, serta selalu ingin diperhatikan. Banyak orang yang mengalami gangguan ini, terutama kalangan remaja. Namun sebagian besar dari penderita gangguan ini kurang menyadari kondisinya dan menolak untuk melakukan konsultasi ke psikolog atau psikiater. Oleh sebab itu, dibutuhkan suatu sistem pakar yang dapat membantu untuk mendiagnosis secara mandiri gangguan kepribadian histerik dan mampu memberikan solusi penanganan yang tepat. Sistem tersebut dibangun dengan menggunakan metode waterfall dan metode certainty factor sebagai metode kepakarannya. Hasil dari penelitian ini adalah sistem pakar berbasis web untuk mendiagnosis tingkat gangguan kepribadian histerik. Sistem akan menampilkan nilai kepastian dan tingkat gangguan kepribadian histerik yang dialami pengguna, serta solusi penanganannya. Uji hasil kepakaran dilakukan dengan cara membandingkan hasil diagnosis dari sistem dengan hasil diagnosis dari pakar. Hasil uji kepakaran menunjukkan bahwa hasil diagnosis sistem sudah mendekati kebenaran dari diagnosis seorang pakar. Nilai prosentase sistem sebesar 83,01% dan nilai prosentase pakar sebesar 83,3%. Dengan adanya sistem pakar ini, masyarakat umum dapat melakukan diagnosis mandiri untuk mengetahui tingkat gangguan kepribadian histerik yang dialami serta penanganannya dengan mudah tanpa harus datang ke psikolog.

Sistem Informasi Absensi Haul Berbasis Web di Pondok Pesantren Muhyiddin Surabaya
Jannah, Erliyah Nurul
Arifin, Agus Zainal
Teknologi informasi saat ini telah menjadi kebutuhan bagi hampir semua instansi, baik pemerintah maupun swasta. Tak terkecuali pondok pesantren, khususnya Pondok Pesantren Muhyiddin Surabaya. Berbagai permasalahan di pondok pesantren membutuhkan bantuan teknologi informasi dalam penyelesaiannya. Salah satunya adalah permasalahan pencatatan kehadiran peserta dalam suatu acara tertentu seperti acara Haul. Haul merupakan acara tahunan yang bertujuan untuk memperingati hari lahirnya Nabi Muhammad SAW. Acara Haul di PP. Muhyiddin mendatangkan lebih dari seribu peserta yang merupakan penghafal Quran. Panitia Haul harus mengabsen peserta satu persatu serta menempatkannya ke majelis-majelis berdasarkan urutan kedatangan dan kota asal. Sistem informasi absensi yang ada masih berbasis desktop dan hanya mampu digunakan untuk mengabsen peserta saja. Sistem tersebut belum mampu melakukan pembagian majelis peserta secara otomatis. Padahal proses pembagian majelis inilah yang menyebabkan proses absensi memakan waktu lama. Oleh sebab itu, dibuatlah sebuah Sistem Informasi Absensi Haul yang berbasis web. Sistem ini diharapkan mampu untuk membuat proses absensi pada acara Haul menjadi lebih efisien. Dari hasil pengujian sistem yang telah dilakukan, dalam satu menit sistem dapat digunakan untuk mengabsen sepuluh peserta, membagi peserta tersebut ke majelis-majelis, dan mencetak kartu peserta Haul.

Adaptif Range-Constrained Otsu Untuk Pemilihan Threshold Secara Otomatis Pada Histogram Citra Dengan Variansi Kelas Yang Tidak Seimbang
Fajarianto, Gama Wisnu
Abror, Ahmad Hifdhul
Hayatin, Nur
Abstrak Image Thresholding merupakan proses segmentasi untuk pemisahkan foreground dan background pada citra dengan cara membagi histogram citra menjadi dua kelas. Beberapa metode thresholding seperti Otsu dan Range-constrained Otsu menggunakan nilai variansi dari histogram untuk mendapatkan titik threshold, namun ketika menangani citra yang memiliki nilai variansi kelas foreground dan background tidak seimbang titik threshold yang dihasilkan kurang tepat. Paper ini mengusulkan metode Adaptif Range-constrained Otsu untuk mengatasi permasalahan variansi kelas yang tidak seimbang dengan cara mencari kelas yang memiliki nilai variansi lebih besar, untuk mendapatkan titik threshold yang lebih tepat. Pengujian menggunakan 22 NDT image dengan evaluasi misclassification error rate dan metode perankingan menunjukkan metode ini menghasilkan rerata ME 0.1153. Sedangkan Otsu sebesar 0.1746. Nilai rerata ranking 3.55, selisih 0.05 dibanding Kittler III. Hasil ini menunjukkan metode yang diusulkan kompetitif, terutama untuk segmentasi citra yang memiliki variansi kelas tidak sama. Kata kunci: segmentasi, thresholding, histogram, Otsu, Range-constrained. Abstract Image thresholding is segmentation process for separating foreground and background of an image by dividing image histogram into two classes. Several thresholding methods like Otsu and Rangeconstrained Otsu using the variance value of the histogram to get the threshold point, but when handling images that have unbalance class variance of the foreground and background produce less accurate threshold point. This paper proposes a method Adaptive Range-constrained Otsu to solve unbalance class variance problem by finding a class that has greater variance value to obtain more accurate threshold point. NDT testing using 22 images with misclassification error rate evaluation and ranking methods shows that this method results ME average of 0.1153, while Otsu method results 0.1746. The rankings mean value is 3.55, which has the difference of 0.05 when compared with Kittler III. These results show that the proposed method is competitive, especially for image segmentation with different class variance. Key word: segmentasi, thresholding, histogram, Otsu, Range-constrained.

Segmentasi Citra menggunakan Support Vector Machine (SVM) dan Ellipsoid Region Search Strategy (ERSS) Arimoto Entropy berdasarkan Ciri Warna dan Tekstur
Hakim, Lukman
Mutrofin, Siti
Ratnasari, Evy Kamilah
Segmentasi citra merupakan suatu metode penting dalam pengolahan citra digital yang bertujuan membagi citra menjadi beberapa region yang homogen berdasarkan kriteria kemiripan tertentu. Salah satu syarat utama yang harus dimiliki suatu metode segmentasi citra yaitu menghasilkan citra boundary yang optimal.Untuk memenuhi syarat tersebut suatu metode segmentasi membutuhkan suatu klasifikasi piksel citra yang dapat memisahkan piksel secara linier dan non-linear. Pada penelitian ini, penulis mengusulkan metode segmentasi citra menggunakan SVM dan entropi Arimoto berbasis ERSS sehingga tahan terhadap derau dan mempunyai kompleksitas yang rendah untuk menghasilkan citra boundary yang optimal. Pertama, ekstraksi ciri warna dengan local homogeneity dan ciri tekstur dengan menggunakan Gray Level Co-occurrence Matrix (GLCM) yang menghasilkan beberapa fitur. Kedua, pelabelan dengan Arimoto berbasis ERSS yang digunakan sebagai kelas dalam klasifikasi. Ketiga, hasil ekstraksi fitur dan training kemudian diklasifikasi berdasarkan label dengan SVM yang telah di-training. Dari percobaan yang dilakukan menunjukkan hasil segmentasi kurang optimal dengan akurasi 69 %. Reduksi fitur perlu dilakukan untuk menghasilkan citra yang tersegmentasi dengan baik. Kata kunci: segmentasi citra, support vector machine, ERSS Arimoto Entropy, ekstraksi ciri. Abstract Image segmentation is an important tool in image processing that divides an image into homogeneous regions based on certain similarity criteria, which ideally should be meaning-full for a certain purpose. Optimal boundary is one of the main criteria that an image segmentation method should has. A classification method that can partitions pixel linearly or non-linearly is needed by an image segmentation method. We propose a color image segmentation using Support Vector Machine (SVM) classification and ERSS Arimoto entropy thresholding to get optimal boundary of segmented image that noise-free and low complexity. Firstly, the pixel-level color feature and texture feature of the image, which is used as input to SVM model (classifier), are extracted via the local homogeneity and Gray Level Co-Occurrence Matrix (GLCM). Then, determine class of classifier using Arimoto based ERSS thresholding. Finally, the color image is segmented with the trained SVM model (classifier). This image segmentation result less satisfied segmented image with 69 % accuracy. Feature reduction is needed to get an effective image segmentation. Key word: image segmentation, support vector machine, ERSS Arimoto Entropy, feature extraction.

Mentari, Mustika
Sari, Yuita Arum
Dewi, Ratih Kartika
Seiring perkembangan teknologi dilakukan otomatisasi deteksi kanker kulit melalui citra dermoscopy. Pengambilan informasi fitur citra dermoscopy terganggu dengan outlier dan overfitting, karena faktor jenis kulit, penyebaran kanker yang tidak merata atau kesalahan sampling. Penelitian ini mengusulkan deteksi kanker kulit melanoma dengan mengintegrasikan metode fuzzy K-Nearest Neighbour (FuzzykNN), Lp-norm dan Linear Discriminant Analysis (LDA) untuk mengurangi outlier dan overfitting. Masukan berupa citra warna RGB yang dinormalisasi menjadi RGBr. Reduksi dimensi dengan LDA menghasilkan fitur dengan nilai eigen paling menonjol. LDA pada penelitian ini menghasilkan dua fitur paling menonjol dari 141 jenis fitur, yaitu wilayah tumor dan minimum wilayah tumor channel R. Kemudian dilakukan klasifikasi FuzzykNN dan metode pengukur jarak Lp-norm. Penggunaan metode LDA dan Lp-norm dalam proses klasifikasi ini mengatasi terjadinya overfitting. Akurasi yang dihasilkan metode LDA-fuzzykNN Lp Norm, yaitu 72% saat masing-masing nilai p dan k = 25. Metode gabungan ini terbukti cukup baik dari pada metode yang dijalankan terpisah. Kata kunci: melanoma, fuzzy, KNN, Lp-norm, LDA. As the advancement of technology skin cancer detection need to be automated with the use of dermoscopy image. Outlier and overfitting are the problem in feature extraction of dermoscopy image, this can be caused by skin type, uneven cancer distribution or sampling error. This study proposed melanoma skin cancer detection by fuzzy K-Nearest Neighbour (FuzzykNN) with Lp-norm integrated with Linear Discriminant Analysis (LDA) to reduce the problem of outlier and overfitting. Input used in this study are images with RGB channel, then it adapted to RGBr. Dimensional reduction with LDA result in features with highest eigen value. LDA in this research select 2 discriminant, they are tumor area and minimum tumor area in R channel. This features then classified by fuzzykNN with Lp-Norm. Integration of LDA and Lp-norm in classification can reduce the problem of overfitting. This study results in 72% accuracy when the value of p and k are 25. Integration of LDA and fuzzykNN with Lp-norm has better result than unintegrated method. Keywords: melanoma, fuzzy, KNN, Lp-norm, LDA.

Perguruan Tinggi merupakan salah satu institusi yang menyimpan data yang sangat informatif jika diolah secara baik. Prediksi kelulusan mahasiswa merupakan kasus di Perguruan Tinggi yang cukup banyak diteliti. Dengan mengetahui prediksi status kelulusan mahasiswa di tengah semester, dosen dapat mengantisipasi atau memberi perhatian khusus pada siswa yang diprediksi tidak lulus. Metode yang digunakan sangat bervariatif termasuk metode Fuzzy Inference System (FIS). Namun dalam implementasinya, proses pembangkitan rule fuzzy sering dilakukan secara random atau berdasarkan pemahaman pakar sehingga tidak merepresentasikan sebaran data. Oleh karena itu, dalam penelitian ini digunakan teknik Decision Tree (DT) untuk membangkitkan rule. Dari uraian tersebut, penelitian bertujuan untuk memprediksi kelulusan mata kuliah menggunakan hybrid FIS dan DT. Data yang digunakan dalam penelitian ini adalah data nilai Posttest, Tugas, Kuis, dan UTS dari 106 mahasiswa Politeknik Kediri pengikut mata kuliah Algoritma dan Struktur Data. Penelitian ini diawali dari membangkitkan 5 rule yang selanjutnya digunakan dalam inferensi. Tahap selanjutnya adalah implementasi FIS dengan tahapan fuzzifikasi, inferensi, dan defuzzifikasi. Hasil yang diperoleh adalah akurasi, sensitivitas, dan spesifisitas masing-masing adalah 94.33%, 96.55%, dan 84.21%. College is an institution that holds very informative data if it mined properly. Prediction about student’s graduation is a common case that many discussed. Having the predictions of student’s graduation in the middle semester, lecturer will anticipate or give some special attention to students who would be not passed. The method used to prediction is very varied including Fuzzy Inference System (FIS). However, fuzzy rule process is often generated randomly or based on knowledge experts that not represent the data distribution. Therefore, in this study, we used a Decision Tree (DT) technique for generate the rules. So, the research aims to predict courses graduation using hybrid FIS and DT. Dataset used is the posttest score, tasks score, quizzes score, and middle test score from 106 students of the Polytechnic Kediri who took Algorithms and Data Structures. The research started by generating 5 rules by decision tree. The next is implementation of FIS that consist of fuzzification, inference, and defuzzification. The results show that the classifier give a good result in an accuracy, sensitivity, and specificity respectively was 94.33%, 96.55% and 84.21%.

Prediction of Increasing Production Activities using Combination of Query Aggregation on Complex Events Processing and Neural Network
Arwan, Achmad
Produksi, order, penjualan, dan pengiriman adalah serangkaian event yang saling terkait dalam industri manufaktur. Selanjutnya hasil dari event tersebut dicatat dalam event log. Complex Event Processing adalah metode yang digunakan untuk menganalisis apakah terdapat pola kombinasi peristiwa tertentu (peluang/ancaman) yang terjadi pada sebuah sistem, sehingga dapat ditangani secara cepat dan tepat. Jaringan saraf tiruan adalah metode yang digunakan untuk mengklasifikasi data peningkatan proses produksi. Hasil pencatatan rangkaian proses yang menyebabkan peningkatan produksi digunakan sebagai data latih untuk mendapatkan fungsi aktivasi dari jaringan saraf tiruan. Penjumlahan hasil catatan event log dimasukkan ke input jaringan saraf tiruan untuk perhitungan nilai aktivasi. Ketika nilai aktivasi lebih dari batas yang ditentukan, maka sistem mengeluarkan sinyal untuk meningkatkan produksi, jika tidak, sistem tetap memantau kejadian. Hasil percobaan menunjukkan bahwa akurasi dari metode ini adalah 77% dari 39 rangkaian aliran event.Kata kunci: complex event processing, event, jaringan saraf tiruan, prediksi peningkatan produksi, proses. Productions, orders, sales, and shipments are series of interrelated events within manufacturing industry. Further these events were recorded in the event log. Complex event processing is a method that used to analyze whether there are patterns of combinations of certain events (opportunities / threats) that occur in a system, so it can be addressed quickly and appropriately. Artificial neural network is a method that we used to classify production increase activities. The series of events that cause the increase of the production used as a dataset to train the weight of neural network which result activation value. An aggregate stream of events inserted into the neural network input to compute the value of activation. When the value is over a certain threshold (the activation value results from training process), the system will issue a signal to increase production, otherwise system will keep monitor the events. Experiment result shows that the accuracy of this method is 77% for 39 series of event streams.Keywords: complex event processing, event, neural networks, process, production increase prediction.

Game Design Document Format For Video Games With Passive Dynamic Difficulty Adjustment
Atmaja, Pratama Wirya
Siahaan, Daniel Oranova
Kuswardayan, Imam
Permainan video adalah perangkat lunak hiburan, sehingga kepuasan pemainnya adalah tolok ukur utama kualitasnya. Satu elemen penting dari kepuasan pemain adalah tingkat kesulitan yang tepat, yang tidak terlalu mudah maupun sukar. Dewasa ini, cara termutakhir untuk menerapkan tingkat kesulitan yang tepat adalah Pengaturan Kesulitan Dinamis (PKD), yang dapat memodifikasi tingkat kesulitan permainan pada saat run-time. Tipe PKD yang paling populer pada saat ini adalah PKD pasif. Di sisi lain, Dokumen Desain Permainan (DDP) adalah artefak penting dalam pengembangan perangkat lunak permainan video, dan belum ditemukan format DDP yang mendukung perancangan mekanisme PKD pasif. Tujuan penelitian ini adalah menemukan format DDP baru yang mendukung perancangan tersebut. Kami memodifikasi sebuah format DDP yang bersifat umum dengan menambahkan bagian-bagian baru untuk perancangan mekanisme PKD pasif. Format hasil modifikasi tersebut diuji dalam proses pengujian yang melibatkan sejumlah pengembang dan sejumlah pemain. Para pengembang mengembangkan sejumlah permainan video menggunakan format DDP yang dimodifikasi dan format yang umum. Proses pengembangan yang mereka jalani diamati dan dinilai kelancarannya. Permainan-permainan video yang dihasilkan dengan kedua format DDP dimainkan oleh para pemain untuk menguji kualitas mekanisme PKD pasifnya. Hasil pengujian oleh para pengembang menyatakan bahwa format DDP yang dimodifikasi lebih baik dari format yang umum. Hasil pengujian oleh para pemain menunjukkan keunggulan permainan-permainan video yang dihasilkan dengan format DDP yang dimodifikasi, walau keunggulan itu tidak signifikan. Berdasarkan hasil tersebut, kami menyatakan bahwa format DDP yang dimodifikasi berhasil mencapai tujuannya.Kata kunci: permainan video, rekayasa kebutuhan, Pengaturan Kesulitan Dinamis, dokumen desain permainan, pengembangan perangkat lunak. Video game is a type of entertainment software, and therefore the satisfaction of its players is the primary mean to measure its quality. One important element of player’s satisfaction is a proper difficulty level, which is neither too easy nor too hard. The current state-of-the-art way to implement it is with Dynamic Difficulty Adjustment (DDA), which allows the difficulty level of a video game to be adjusted at run-time. Currently, the most popular type of DDA is the passive one. Meanwhile, Game Design Document (GDD) is an important artefact in the development process of a video game software, and there is still no GDD format that supports the design of passive DDA mechanism. The aim of this research was to find a new GDD format that supports the mechanism. We modified a general purpose GDD format by adding new parts for designing passive DDA mechanism. We tested the usefulness of the modified format in a testing process involving developers and players. The developers developed video games using the modified GDD format and the general purpose one. Their development processes were observed and evaluated to know if there were any difficulties. The resulting video games were played by the players to find which are better in terms of passive DDA mechanism. The result of developer testing showed that the modified format is better than the general purpose one. The result of player testing showed that the video games made with the modified format are better than their counterparts, albeit by an insignificant margin. Based on the results, we declare that the modified GDD format is successful.Keywords: Video game, requirement engineering, game design document, dynamic difficulty adjustment, software development.

Penyakit noda pada daun tanaman tebu menampakkan gejala berupa lesi atau bercak. Lesi tersebut menghambat proses fotosintesis daun dan dapat mengakibatkan menurunnya produksi gula. Oleh karena itu, dalam meningkatkan kualitas produksi gula dibutuhkan diagnosa dini untuk mengambil keputusan penanganan penyakit yang cepat dan tepat, sehingga dapat meminimalisir kerusakan daun yang signifikan akibat penyebaran penyakit tersebut. Sayangnya keterbatasan keberadaan ahli penyakit tanaman tebu yang berpotensi dalam mendiagnosa penyakit noda tidak dapat mengatasi hal tersebut. Penelitian ini mengusulkan diagnosa penyakit noda tanaman tebu menggunakan metode pemrosesan citra berdasarkan fitur tekstur Segmentation-based Gray Level Co-Occurrence Texture (SGLCM) dan LAB color moments. Metode yang diajukan terdiri dari ekstraksi ciri warna pada citra masukan yang akan menghasilkan 12 fitur warna dan ekstraksi ciri tekstur pada citra masukan yang tersegmentasi dan menghasilkan 24 fitur tekstur, kemudian gabungan fitur warna dan tekstur tersebut digunakan sebagai masukan klasifikasi k-Nearest Neighbor (kNN) untuk mengenali jenis penyakit noda pada citra daun tanaman tebu. Jenis penyakit noda terdiri dari noda cincin, noda karat, dan noda kuning yang memiliki karakteristik berbeda. Klasifikasi penyakit noda pada tanaman tebu menggunakan metode tersebut dapat menghasilkan akurasi tertinggi 93%. The sugarcane spot disease attack the sugarcane with appear as spots on the leaves, so this spots prevent the vital process of photosynthesis to take place and caused sugar production losses. Early diagnosis of this spot disease can improve the quality of sugar production. The diagnosis result can be used as decision reference to control the disease fast and accurately to minimize attack severe that can caused significant damage. Unfortunately, experts who are able to identify the diseases are often unavailable. This research attempted to identify the three sugarcane spot diseases (ring spot, rust spot, and yellow spot) using Segmentation-based Gray Level Co-Occurrence Texture (SGLCM) and LAB color moments. The SGLCM obtain 24 texture features of segmented image and color moments obtain 12 color features. This method achieved at least 93% accuracy when identifying the diseases using kNN classifier.

Buah Mengkudu merupakan komoditi ekspor yang sedang berkembang di Indonesia. Proses pengklasifikasian kematangan buah Mengkudu perlu dilakukan agar kualitas buah Mengkudu yang di ekspor dapat terjamin. Proses klasifikasi dengan jumlah yang banyak akan sulit apabila dilakukan secara manual. Oleh karena itu, penelitian ini diperlukan untuk menghasilkan proses otomatisasi klasifikasi kematangan buah Mengkudu. Metode yang diusulkan untuk melakukan otomatisasi klasifikasi adalah proses pengenalan karakteristik buah Mengkudu berdasarkan fitur tekstur dan warna. Fitur tektur dan fitur warna didapatkan melalui proses pengolahan citra digital buah Mengkudu. Penelitian ini membuktikan bahwa pengklasifikasian buah Mengkudu dengan algoritma Support Vector Machines (SVM) menghasilkan nilai persentase lebih tinggi dari pada menggunakan algoritma k-Nearest Neighbors (KNN). Hasil persentase tertinggi yang didapatkan yaitu sebesar 87.22%. Noni fruit is an export commodities that were flourishing in Indonesia. Noni fruit maturity classification process should be done in order the quality of the noni fruit which is exported can be guaranteed. Classification process in large quantities will be difficult if it is done manually. Therefore this research is needed to produce an automation classification process of noni fruit ripeness. The proposed method is characteristic introduction of noni fruit based on texture and color features. Texture and color features are obtained from digital image processing of noni fruit. This research proves that the classification of noni fruit with SVM algorithm produces better accuracy than using KNN algorithm. The highest accuracy is equal to 87.22%.

Permainan pada smartphone merupakan aplikasi yang banyak digunakan orang untuk menghabiskan waktu ketika orang tersebut sedang dalam keadaan menunggu atau bosan. Industri game merupakan perwujudan pengembangan industri kreatif yang ada pada saat ini. Perkembangan permainan pada smartphone juga didukung dengan kemajuan grafis yang membuat lingkungan dan jalannya permainan terlihat lebih realistis. Game akan terlihat lebih realistis jika memiliki Artificial Intelligence (AI) pada karakternya khususnya pada Non-Player Character (NPC). Ketika sebuah game sudah memiliki AI yang baik, berarti bahwa karakter permainan menunjukkan perilaku yang konsisten dan realistis, bereaksi dengan tepat kepada tindakan pemain dan karakter lain. Pada game AI, ada banyak metode yang bisa digunakan untuk memberikan perilaku pada NPC salah satunya adalah metode Jaringan Saraf Tiruan (JST). Makalah ini memberikan sebuah perubahan perilaku pada NPC dengan menggunakan algoritma Perceptron. Perubahan perilaku akan diproses menyesuaikan jumlah mufradat dan jumlah poin yang didapatkan pemain. Berdasarkan hasil pengujian dapat disimpulkan bahwa implementasi Perceptron untuk memberikan perilaku pada NPC pada Game Arabic Hunter dapat berjalan dengan baik. Dari hasil uji coba algoritma, pada proses learning dapat diketahui bahwa semakin besar nilai learning rate, maka semakin kecil nilai epoch yang didapat. Dari uji coba tersebut dihasilkan learning rate = 1, threshold = 0.6, nilai bias = -1, waktu eksekusi = 1.433 detik. Pada proses learning dihasilkan 93% berhasil dan 7% gagal. Games on the smartphone is an application that people use to pass the time when the person is in a state of waiting or bored. Game industry is a manifestation of the development of creative industries that exist at this time. Game development on the smartphone is also supported by the progress of graphics that make the environment and the game more realistic. The game will look more realistic if it has artificial intelligence (AI) on its character especially on Non-Player Character (NPC). When a game already has a good AI, it means that the game characters show consistent and realistic behavior, reacting appropriately to the actions of players and other characters. In the game AI, there are many methods that can be used to give the NPC behavior in one of which is a method of an artificial neural network. This paper provides a behavioral change in the NPC using Perceptron algorithm. Changes in behavior will be processed mufradat adjust the amount and number of points earned player. Based on the test results can be concluded that the implementation of the Perceptron to give the NPC behavior in Arabic game hunter can run well. From the test results of the algorithm, the learning process can be seen that the greater the value of learning rate, the smaller value epoch obtained. From these trials generated learning rate = 1, threshold = 0.6, the value of bias = -1, the execution time = 1.433 seconds. In the learning process produced 93% success and 7% failed.

Wireless Sensor Network (WSN) merupakan jaringan dengan skalabilitas yang sangat tinggi, dan memiliki jumlah sensor node yang sangat banyak. Untuk efisiensi biaya, sensor node banyak diterapkan dengan menggunakan Arduino. Arduino merupakan papan rangkaian elektronik open source yang di dalamnya terdapat chip mikrokontroler. Dengan keterbatasan resource yang dimiliki oleh Arduino, efisiensi komputasi yang ada di dalam sensor node harus diperhatikan. Salah satunya berkaitan dengan proses komunikasi dan pengiriman data dari sensor node ke sink node (gateway). Restful web service merupakan salah satu protokol komunikasi yang memanfaatkan HTTP. Protokol ini dikenal memiliki efisiensi yang cukup tinggi, di samping karena interoperabilitasnya untuk digunakan pada berbagai platform. Dalam makalah ini akan diuraikan hasil dari implementasi model pull message dengan menggunakan restful web service, pada komunikasi antara sink node (gateway) dengan sensor node, di dalam infrastruktur WSN. Dalam penelitian yang dilakukan, digunakan mikrokontroler Arduino sebagai sensor node, dan Raspberry Pi sebagai sink node. Selain itu juga diimplementasikan mekanisme thread untuk menangani multi-process yang berjalan di dalam sensor node. Hasil dari pengujian menunjukan bahwa interval sensing, ukuran data, dan jumlah sink node yang melakukan request, tidak begitu berpengaruh terhadap ketersedian free memory heap pada sensor node. Sedangkan ukuran dari data hasil sensing yang dikirim mempunyai pengaruh terhadap request-response time. Wireless Sensor Network (WSN) infrastructure has very high scalability, which is composed of a large number of the sensor node. For cost efficiency, sensor node broadly deployed using Arduino. Arduino is the open-source electronic circuit board, which has embedded microcontroller chipset. Due to limited resource, the efficiency of computation inside Arduino must be considered during the development of sensor node. One of them is related to communication and data delivery process between the sensor node and sink node. Restful Web Service is one of communication protocol framework which uses HTTP protocol and claimed to be the most efficient Web Service. As well as the other web services, Restful also support high interoperability of communication. In this paper we describe the implementation of pull message mechanism on WSN communication between the sensor node and sink node, using Restful Web Service. We implemented sensor node using Arduino board, and sink node using Raspberry Pi. We also used thread mechanism to handle multi-process that run in the sensor node. The results of the study show that the interval time in sensing, data size, and the number of sink node which makes requests, didn’t give too much influence in the availability of free memory heap in the sensor node. While the size of sensor data that was sent to sink node have an influence on a request-response time.

Saat ini dengan kemajuan teknologi membuat komputer memiliki kemampuan komputasi yang lebih tinggi untuk meningkatkan kemampuan dalam pengolahan data. Kemajuan teknologi ini juga berimbas pada kemampuan teknologi citra digital yang berhubungan dengan pengenalan karakter angka yang merupakan bagian dari pengenalan pola. Pengenalan karakter penting untuk pengolahan informasi yang memungkinkan proses identifikasi secara cepat dan otomatis. Pada penelitian ini dilakukan proses pengenalan karakter angka menggunakan metode Integral Proyeksi. Alasan menggunakan metode integral proyeksi karena mempunyai kelebihan pemrosesan yang sederhana dan cepat dalam mengidentifikasi suatu citra digital. Integral Proyeksi yang digunakan yaitu Integral Proyeksi vertikal dan Integral Proyeksi horisontal. Hasil penelitian menunjukkan pengenalan karakter angka mampu mengenali karakter dengan benar jika hasil praproses menghasilkan gambar yang baik. Pengenalan karakter angka akan kurang sempurna jika gambar yang diproses tidak baik, hal ini dikarenakan metode Integral Proyeksi bekerja dengan menghitung jumlah piksel tiap gambar untuk mengenai nilai gambar tersebut. Pengujian pengenalan karakater angka yang dilakukan terdapat 20 gambar uji menghasilkan nilai akurasi sebesar 65%. Nowadays with the advancement of technology makes computers have higher computing capabilities to improve the capability of data processing. Advances in technology have also affected the ability of digital image technology related to the introduction of alphanumeric characters that are part of pattern recognition. Character recognition is important for information processing that allows rapid identification process automatically. In this research, numeric character recognition process using integral projection method. Reasons for using integral projection method for processing has the advantage of a simple and quick in identifying a digital image. The integral projection used is vertical projection and horizontal projection. The results showed numeric character recognition could recognize the characters correctly if the results of preprocessing produce good images. The introduction of the characters will be less than perfect if the images are processed is not good, this is because the integral projection method works by counting the number of pixels for each image to the value of the image. Testing the result of recognition from 20 image which is on dataset has been built to get accuracy value about 65%.

Beberapa Perguruan Tinggi Swasta (PTS) di Jombang menerapkan proses seleksi Penerimaan Mahasiswa Baru (PMB) online, sehingga pendaftar cukup mendaftar melalui website PMB online milik masing-masing PTS, tanpa perlu ke Perguruan Tinggi (PT) tersebut. Namun dalam pelaksanaanya masih terdapat calon mahasiswa yang mendaftar secara langsung ke kantor PMB PTS, hal tersebut menjadikan perlunya pengukuran tingkat kesuksesan penerapan website PMB online di PTS. Selain itu, selama ini website PMB online PTS di Jombang belum pernah dilakukan evaluasi untuk mengetahui tingkat keberhasilannya. HOT (Human Organization Technology) Fit model merupakan model kesuksesan yang dapat dijadikan model dalam mengevaluasi sistem informasi. Terdapat 7 variabel yang digunakan HOT Fit, yaitu kualitas sistem (system quality), kualitas informasi (information quality), kualitas layanan (service quality), pengguna sistem (system use), kepuasan pengguna (user satisfaction), manfaat (net beneFits), struktur organisasi (organization structure). Hasil penelitian menunjukkan terdapat 3 indikator penilaian dengan nilai kepuasan di bawah 85%, yaitu kecepatan waktu respon 76,1%; adanya fasilitas bantuan 71,6%; dan kepuasan tampilan 64,2%. Sehingga 3 indikator tersebut perlu ditingkat lagi untuk mendapatkan hasil yang lebih baik dan dapat mengoptimalkan penerapan website PMB online PTS di Jombang. Private Higher Education (PHE) in Jombang apply online admission of new students selection process, so applicants simply register through admission of new students online website owned by their respective private universities, without needing to the university. But in the implementation there are still prospective students who apply directly to the office of admission of new students PHE, it makes the need to measure the success rate of admission of new students website online application in PHE. Also, so far admission of new students online website PHE in Jombang has never been evaluated to determine the success rate. HOT (Human Organization Technology) Fit model is a model of success that can be used as a model for evaluating information systems. There are seven variables used by HOT Fit, i.e., system quality, information quality, service quality, system use, user satisfaction, net beneFits, organizational structure (organization structure). The result of the research shows that there are three assessment indicators with satisfaction value below 85%, the response time is 76,1%; the availability of 71.6% of aid facilities; and 64.2% display satisfaction. So that three indicators need to be increased again to get better results and can optimize the implementation of admission of new students website online PHE in Jombang.

Perkembangan teknologi informasi membuat banyak aspek mengalami perubahan, seperti penerapan Ujian Nasional (UN) bagi siswa Sekolah Menengah Atas (SMA). Sebelumnya, UN diselenggarakan dengan menggunakan media kertas, saat ini beralih menggunakan media komputer. Hal ini memang membawa banyak dampak positif bagi perkembangan dunia pendidikan. Adanya peralihan media ujian ini membuat banyak muncul berbagai aplikasi Ujian Berbasis Komputer (UBK) atau Computer Based Test (CBT), tapi barulah sebatas siswa mengerjakan soal, setelah selesai muncullah hasil ujiannya. Dengan menerapkan ilmu statistik pada aplikasi UBK, pihak sekolah tidak hanya bisa mengetahui hasil akhir dari ujian siswa, tetapi juga dapat melihat berapa jumlah soal yang sulit untuk dikerjakan, pilihan opsi jawaban apa yang banyak dipilih siswa. Dengan adanya perhitungan secara statistik ini, dapat membantu pihak sekolah dalam menganalisa kemampuan para siswa, sehingga bisa mengambil keputusan untuk meningkatkan kemampuan siswa dengan lebih efektif. The development of information technology makes many aspects of the changes, such as the implementation of national examinations for high school students. Previous national exam held using paper media now switched to using computer media. It does bring a lot of positive impact on the development of education. Their intermediate exams media makes many emerging various applications of the computer-based exam, but then the extent of the students do the problems, after completion comes to the test results. By applying the science of statistics on the application of computer-based test not only the school can determine the outcome of the exam students but could see a calculation of how the amount of matter that is difficult to do, choice answer options selected what many students. Given the statistical calculation can help the school in analyzing the ability of the students, so they can make decisions to improve students' ability to more effectively.

Pembuluh darah pada retina merupakan bagian retina yang berfungsi memberikan suplai darah dan oksigen ke dalam retina. Sehingga apabila pembuluh darah tidak tersuplai oksigen, maka dapat ditarik kesimpulan bahwa pembuluh darah retina tersebut bermasalah, banyaknya noise pada daerah pembuluh darah menyebabkan proses dalam segmentasi. Karena permasalahan yang timbul, maka dalam penelitian ini diusulkan metode segmentasi pembuluh darah dengan menggabungkan dua metode, yaitu metode Multi-Scale Line Detector (MSLD) dan Adaptive Morphology. Dari keseluruhan metode memiliki fungsi yang berbeda-beda, MSLD berfungsi dalam proses pemisahan garis yang dibentuk oleh pembuluh darah yang dalam hal ini melalui proses perubahan citra orisinal ke citra green channel, namun dalam proses sebenarnya metode MSLD kurang dalam proses segmentasi, karena timbulnya masalah disaat terjadi garis yang menyilang antara optic disc dan pembuluh darah, sehingga pada saat segmentasi garis yang menyilang tersebut tidak akan ikut disegmentasi, sehingga membutuhkan metode penambahan pada proses segmentasinya, untuk itu diperlukan metode Adaptive Morphology, sehingga saat proses segmentasi sebelumnya yang telah dilakukan dengan menggunakan MSLD bisa disempurnakan dengan menggunakan metode Adaptive Morphology. Penggabungan metode sangat efektif karena bisa menghilangkan area optic disc yang membentuk garis menyilang dengan pembuluh darah secara sempurna dengan tanpa menghilangkan area pembuluh darah, sehingga dalam proses segmentasi dapat menghasilkan tingkat akurasi 97,94%. The blood vessels of the retina are part of the retina that serves to supply blood and oxygen to the retina. So if the blood vessels are not supplied oxygen, it can be concluded that the retinal blood vessels are problematic, the amount of noise in the blood vessel causes the process in segments.Karena problems arise, then in this study proposed method of blood vessel segmentation by combining two methods, namely Methods of Multi-Scale Line Detector (MSLD) and adaptive morphology. From the whole method has different functions, MSLD function in the process of separation of lines formed by blood vessels in this case through the process of changing the original image to the green channel image, but in the actual process of MSLD method is less In the process of segmentation, due to the emergence of the problem when there is a crossing line between the optic disc and blood vessels, so that when the segmentation of the crossed line will not participate in segmentation, thus requiring additional method in the process of segmentation, for that required adaptive morphology method, Previous segmentation that has been done by using MSLD can be enhanced by using adaptive morphology method. Combination method is very effective because it can eliminate the optic disc area that forms a line crossed with blood vessels perfectly without removing the blood vessel area, so in the process of segmentation can produce an accuracy of 97.94%.

Sekolah Menengah Kejuruan (SMK) hendaknya mampu menciptakan siswa siap kerja, tidak hanya di sekolah saja dilakukan tes kesehatan. Pada saat memasuki dunia kerja, para siswa juga akan dites kesehatan oleh perusahaan untuk memastikan riwayat kesehatan calon tenaga kerja. Dalam hal ini, pihak sekolah tentunya tidak ingin jika para siswa tidak bisa masuk ke perusahaan karena terbentur dengan riwayat kesehatan. Oleh karena itu, pemeriksaan kesehatan merupakan salah satu persyaratan utama dalam menyeleksi calon siswa baru pada SMK. Dalam makalah ini akan dikembangkan sebuah sistem penentuan status kesehatan peserta didik SMK yang terkomputerisasi. Model yang digunakan dalam kajian ini adalah Fuzzy Tsukamoto. Metode Fuzzy Tsukamoto dilakukan yang pertama kali untuk menentukan fungsi keanggotaannya, kemudian menentukan rule, dan nantinya kategori akan diklasterisasi ke masing-masing kelompok sesuai dengan rule yang diterapkan. Metode Tsukamoto yang digunakan adalah metode defuzzikfikasi rata-rata terpusat (Center Average Defuzzifier). Kesimpulan yang didapat dari penelitian ini adalah penggunaan Logika Fuzzy dengan metode Tsukamoto dapat menentukan status kesehatan pada calon siswa SMK. Vocational High School should be able to prepare students for ready to work. Medical examination is the last step for recruitment process. It is conducted by the company to ascertain the medical history of the prospective workforce. In this case, the school certainly would not want the students can not get into the company because it collided with a medical history. Therefore, medical examination is one of the main requirements in selecting new students in vocational high school. In this paper, a computerized system for determining the health status of vocational high school student developed. The model used in this study is developed. Fuzzy Tsukamoto determines the membership function, then defines the rule, and the categories will be clustered in to different groups according rule applied. The Tsukamoto which was used here is the Center Average Defuzzifier method. The conclusion obtained from this research is the use of Fuzzy Logic with Tsukamoto method can determine health status in prospective students of vocational high school.

Tulisan ini menganalisis faktor adopsi mobile berdasarkan kriteria pengalaman, usia dan jenis kelamin. Penelitian ini merupakan eksplorasi dan pengembangan lanjutan dari model UTAUT2 (Unified Theory of Acceptance and Use of Technology). Beberapa variabel seperti kebiasaan dan kecemasan telah ditambahkan untuk menjelaskan penerimaan teknologi pada sisi konsumen. Di samping itu variabel moderator pengalaman, usia dan jenis kelamin telah dihipotesiskan pengaruhnya. Data yang digunakan penelitian ini diperoleh hasil pengolahan kuesioner dengan sampel convenient yang melibatkan partisipasi 384 responden. Data yang terkumpul selanjutnya diolah dengan Pemodelan Persamaan Struktur (PPS) atau Structural Equation Modelling (SEM) menggunakan alat bantu aplikasi IBM SPPS 21 dan Amos 22. Hasil dari penelitian ini telah menunjukkan hasil uji empiris yang telah mendukung model teoritis yang diajukan. Dibandingkan dengan hasil penelitian terdahulu, hasil penelitian ini menunjukkan peran dominan nilai harga dan motivasi hedonis sebagai penentu pada niat perilaku. Efek nilai harga berbanding terbalik dengan niat perilaku sedangkan motivasi hedonis berbanding lurus dengan niat perilaku. Implikasi temuan dari variabel moderati yakni pengalaman, usia dan jenis kelamin juga ditemukan memiliki efek terhadap jenis adopsi aplikasi yang digunakan. This paper analyzes mobile adoption factors based on age, gender and experience criteria. This study is an advanced development of UTAUT2 (Unified Theory of Acceptance and Use of Technology) model, that applied in the context of adoption mobile applications. There are some variables such as habits and anxiety have been added to explain the acceptance of technology on the consumer view. In addition, moderator variable age, gender and using experience have been hypothesized. The data used in this study obtained from the questionnaire using the method of convenient sampling with involved the participation of 384 respondents. The collected data is then analyzed by the Structural Equation Modelling (SEM) using IBM SPPS version 21 and Amos version 22 program tools. The results of this study show that the results supported the proposed theoretical model. Compared with the results of previous studies, the results of this study indicate the effect of price value and hedonic motivation as a determinant of behavioral intent. The effect of the value of the price is inversely proportional to the behavioral intention while the hedonic motivation is directly proportional to the behavioral intention. Implications of findings from moderate variables i.e. experience, age and gender were also found to influence the type of adoption of the applications used.

Dynamic Source Routing
Mobile Ad Hoc Network
Vehicular Ad Hoc Network
Routing pada Vehicular Ad Hoc Network (VANET) merupakan kasus yang unik karena tingginya perubahan jaringannya. VANET sendiri juga digolongkan dalam Mobile Ad Hoc Network (MANET), sehingga protokol-protokol routing yang ada pada MANET dapat juga dipakai pada VANET. Pemilihan protokol routing menjadi salah satu aspek yang cukup penting. Oleh karena itu, penelitian ini akan melakukan evaluasi seberapa kuatnya protokol Dynamic Source Routing (DSR) dalam menghadapi berbagai skenario VANET yang memiliki kepadatan bervariasi di dalam lalu lintas perkotaan. Digunakan protokol 802.11p dalam ruang lingkup lalu lintas perkotaan yang didapat dari SUMo simulator, dan dianalisa menggunakan NS-2. Pemilihan 802.11p juga dipilih dari hasil perbandingan antara 802.11p dan 802.11a pada ruang lingkup lalu lintas yang berbentuk grid yang didapat juga dari simulator yang sama. Dari hasil analisa menunjukkan bahwa 802.11p memiliki performa yang lebih bagus dan bervariasi terhadap kepadatan-kepadatan yang telah ditentukan. Routing on Vehicular Ad Hoc Network (VANET) is a unique case due to the high network changes. VANET itself is also classified in Mobile Ad Hoc Network (MANET), so the MANET routing protocols can also be used on VANET. Selection of routing protocols becomes one of the most important aspects. Therefore, this study will evaluate how strong the Dynamic Source Routing (DSR) protocol in dealing with various VANET scenarios that have varied densities in urban traffic. This research is using an 802.11p protocol that obtained from SUMO simulator and then analyzed by NS-2. The 802.11p protocol was selected based on the result of performance comparison between 802.11p and 802.11a on some grid-shaped traffic scenarios. The results show that 802.11p has better performance and more robust than 802.11a while using predefined densities.

Sistem e-farmers merupakan sebuah sistem penjualan berbasis teknologi (e-commerce) yang dapat diakses melalui website, digunakan untuk membantu para petani menjual hasil pertanian berupa beras secara langsung ke konsumen. Namun dengan adanya kendala dalam hal kepemilikan perangkat komputer dan laptop, petani maupun konsumen yang merupakan pengakses website ladangku.id beralih menggunakan perangkat mobile. Dengan alasan ini, maka peneliti membuat sebuah sistem e-farmers yang awalnya berupa website dapat juga diakses melalui perangkat mobile dengan sistem operasi Android. Karena sistem berbasis website berbeda dengan sistem berbasis mobile, untuk itu dibutuhkan sebuah perancangan sistem e-farmer yang berbasis mobile yang akan terintegrasi dengan sistem berbasis website. Di mana metode yang digunakan adalah metode Research and Development (R&D), yang mana mengembangkan sistem yang sudah ada dan hasil akhirnya menghasilkan sebuah produk berupa rancangan sistem aplikasi e-farmers yang dapat berkerja di platform Android. E-farmers system is a technology-based commerce system (e-commerce) that can be accessed via a website, used for assisting farmers in selling rice product directly to consumers. However, due to the constraint in the ownership of computer and laptop, farmers and consumers as the users of the website ladangku.id now use mobile devices instead. For this reason, the researcher developed an e-farmers system that was initially only accessible via the website but now can be accessed via mobile devices with the Android operating system. Because the website-based system and mobile-based system are different, it is necessary to have a mobile-based e-farmer system design that is integrated with the website-based system. The method used was Research and Development (R&D) method by developing the existing system, and the final product was in the form of a design of e-farmer application system that can work on Android platform.

peringkasan dokumen
Peringkasan dokumen berita Bahasa Indonesia dapat membantu untuk menemukan ide-ide pokok atau informasi penting lain dari sebuah berita. Berita umumnya terdiri atas banyaknya paragraf menjadi sebab diperlukan sebuah sistem untuk mengekstrak informasi, sehingga mampu memberikan ide pokok atau informasi penting yang tepat kepada pembaca, tanpa harus membaca secara detail keseluruhan isi berita tersebut, di samping itu dapat dimanfaatkan guna keperluaan Really Simple Syndication Feed (RSS-Feed). Penelitian ini memaparkan peringkasan dokumen berita berbahasa Indonesia menggunakan metode Cross Latent Semantic Analysis (CLSA) dan Latent Semantic Analysis (LSA). Untuk menguji seberapa baik hasil ringkasan yang dilakukan CLSA penelitian ini menggunakan 240 artikel berita yang diambil dari halaman portal www.kompas.com dan dua pakar yang berlatar belakang bidang yang berbeda. Hasil ringkasan CLSA dengan compression rate 30% memperoleh nilai F-Measure 0.72%. Penelitian ini juga menemukan fakta bahwa CLSA lebih baik dari metode LSA yang merupakan cikal bakal dari metode CLSA, walaupun skor hasil F-Measure keduanya tidak berbeda jauh. Summarizing news documents in Bahasa serves to find main ideas or any other important information from a piece of news. A system to extract the information from ones consisting of many paragraphs is then deemed necessary in order to present precise main ideas or important information to the readers without them having to read the entire passage of news documents, in addition to become useful for Really Simple Syndication Feed (RSS-Feed). This article discusses summarizing news documents in Bahasa using Cross Latent Semantic Analysis (CLSA). To test if the summary resulted from CLSA qualified, this study examines 240 news articles retrieved from www.kompas.com and employs two experts from different fields. The summary resulted from CLSA with a compression rate of 30% obtains an F-Measure of 0.72%. This study also evidently indicates that CLSA has better performance from Latent Semantic Analysis (LSA) which was the initial system for CLSA, despite both F-Measure percentages being only slightly different.

Port Knocking merupakan proses autentikasi yang dilakukan dengan mengetuk port tertentu untuk membuka dan menutup koneksi menuju suatu service. Pada umumnya, Port Knocking memiliki prosedur penetapan daftar port yang bersifat tetap. Hal inilah yang mendorong munculnya penelitian terkait penerapan Secure Random Port List Generator (SRPLG), melalui perancangan sebuah sistem yang mampu mengacak daftar port yang digunakan untuk knocking. Di samping itu, sistem ini juga didesain agar mampu mengirimkan informasi daftar port teracak tersebut kepada client melalui jalur aman. SRPLG server ini akan di integrasikan pada mekanisme autentikasi Port Knocking. Penerapan metode ini bertujuan untuk menciptakan sebuah prosedur autentikasi yang dinamis, aman dan efisien dalam mengamankan Secure Shell server (SSH server). Hasil pengujian yang didapatkan menunjukkan bahwa SRPLG server dalam mengacak daftar Port Knocking mampu menghasilkan daftar port yang selalu berubah setiap kali ada request dari client. Kemudian dari hasil sniffing yang dilakukan terhadap data yang ditransmisikan oleh SRPLG server dan client menunjukkan bahwa seluruh informasi yang ditangkap telah dienkripsi oleh Secure Socket Layer (SSL). Hasil pengujian peforma SRPLG server terhadap jumlah client yang melakukan request, rata-rata membutuhkan waktu antara 0,01 detik sampai 0,06 detik dalam setiap variasi pengujian peformansi. Pengujian terakhir menunjukkan bahwa SSH server telah berhasil diamankan dengan konfigurasi Port Knocking dari serangan port scanning attack, di mana seluruh informasi port yang ditampilkan, tidak ditemukan satupun celah yang dapat eksploitasi. Port Knocking is an authentication process done by tapping a particular port to open and close the connection to a service. In general, the knocking port has a fixed procedure to assign ports list. This is what prompted the emergence of research related to the implementation of Secure Random Port List Generator (SRPLG), through the design of a system capable of scrambling the list of ports used for knocking. In addition, the system is also designed to be able to transmit random ports list information to clients via a secure path. This SRPLG server will be integrated into the Port Knocking authentication mechanism. Implementation of this method aims to create a dynamic authentication procedure, secure and efficient in securing the SSH server. The test results show that the secure random port list generator server in scrambling the list of knocking ports is able to generate an ever-changing port list every time a client requests. Then from the sniffing done to the data transmitted by the SRPLG server and the client indicates that all captured information has been encrypted by secure socket layer or SSL. Performance test marks SRPLG server to the number of clients who make requests, average takes between 0.01 seconds to 0.06 seconds in every variation of performance testing. In the last test shows SSH server has been successfully secured with Port Knocking configuration from attack port scanning attack, where all port information is displayed, not found any fault that can exploit.

Diagnosis suatu penyakit akan menjadi tepat jika didukung dengan berbagai proses mulai pengecekan awal (amannesa) sampai pengecekan laboratorium. Hasil dari proses laboratorium mempunyai informasi berbagai penyakit, akan tetapi beberapa jenis penyakit memiliki prevalensi rendah. Penyakit bervalensi rendah memiliki pengaruh dalam penanganan pasien lebih lanjut. Dengan rasio yang tidak seimbang data laboratorium akan menyebabkan nilai akurasi menjadi rendah dalam pengklasifikasian dan penanganan penyakit. Majority Weighted Minority Oversampling Technique (MWMOTE) adalah saalah satu cara untuk menyelesaikan imbalanced. Penelitian ini bertujuan menangani permasalahan ketidakseimbangan data laboratorium kesehatan sehingga diperoleh hasil pengklasifikasian penyakit dengan tingkat akurasi lebih tinggi. Hasil pada penelitian ini menunjukkan bahwa MWMOTE dapat meningkatkan akurasi untuk permasalahan ketidakseimbangan data sebesar 3,13%. Diagnosis of a disease will be appropriate if supported by various processes ranging from initial checks (amannesa) to laboratory checks. Results from the laboratory process have information on various diseases, but some types of diseases have a low prevalence. Low-valvature disease has an effect in the treatment of the patient further. With an unbalanced ratio the laboratory data will cause the accuracy value to be low in the classification and handling of the disease. Majority Weighted Minority Oversampling Technique (MWMOTE) is one way to complete imbalanced. This study aims to address the problem of imbalance of health laboratory data to obtain the results of the classification of disease with a higher degree of accuracy. The results of this study indicate that MWMOTE can improve accuracy for data imbalance problems by 3.13%.

Sistem deteksi kejadian dari data Twitter bertujuan untuk mendapatkan data secara real-time sebagai alternatif sistem deteksi kejadian yang murah. Penelitian tentang sistem deteksi kejadian telah dilakukan sebelumnya. Salah satu modul utama dari sistem deteksi kejadian adalah modul klasifikasi jenis kejadian. Informasi dapat diklasifikasikan sebagai kejadian penting jika memiliki entitas yang merepresentasikan di mana lokasi kejadian terjadi. Beberapa penelitian sebelumnya masih memanfaatkan fitur ‘buatan tangan’, maupun fitur model berbasis pipeline seperti n-gram sebagai penentuan fitur kunci klasifikasi yang tidak efektif dengan performa kurang optimal. Oleh karena itu, diusulkan penggabungan metode Neuro Named Entity Recognition (NeuroNER) dan klasifier Recurrent Convolutional Neural Network (RCNN) yang diharapkan dapat melakukan deteksi kejadian secara efektif dan optimal. Pertama, sistem melakukan pengenalan entitas bernama pada data tweet untuk mengenali entitas lokasi yang terdapat dalam teks tweet, karena informasi kejadian haruslah memiliki minimal satu entitas lokasi. Kedua, jika tweet terdeteksi memiliki entitas lokasi maka akan dilakukan proses klasifikasi kejadian menggunakan klasifier RCNN. Berdasarkan hasil uji coba, disimpulkan bahwa sistem deteksi kejadian menggunakan penggabungan NeuroNER dan RCNN bekerja dengan sangat baik dengan nilai rata-rata precision, recall, dan f-measure masing-masing 94,87%, 92,73%, dan 93,73%. The incident detection system from Twitter data aims to obtain real-time information as an alternative low-cost incident detection system. One of the main modules in the incident detection system is the classification module. Information is classified as important incident if it has an entity that represents where the incident occurred. Some previous studies still use 'handmade' features as well as feature-based pipeline models such as n-grams as the key features for classification which are deemed as ineffective. Therefore, this research propose a combination of Neuro Named Entity Recognition (NeuroNER) and Recurrent Convolutional Neural Network (RCNN) as an effective classification method for incident detection. First, the system perform named entity recognition to identify the location contained in the tweet text because the event information should have at least one location entity. Then, if the location is successfully identified, the incident will be classified using RCNN. Experimental result shows that the incident detection system using combination of NeuroNER and RCNN works very well with the average value of precision, recall, and f-measure 92.44%, 94.76%, and 93.53% respectively.

peringkasan multi-dokumen
News Feature Scoring (NeFS) merupakan metode pembobotan kalimat yang sering digunakan untuk melakukan pembobotan kalimat pada peringkasan dokumen berdasarkan fitur berita. Beberapa fitur berita diantaranya seperti word frequency, sentence position, Term Frequency-Inverse Document Frequency (TF-IDF), dan kemiripan kalimat terhadap judul. Metode NeFS mampu memilih kalimat penting dengan menghitung frekuensi kata dan mengukur similaritas kata antara kalimat dengan judul. Akan tetapi pembobotan dengan metode NeFS tidak cukup, karena metode tersebut mengabaikan kata informatif yang terkandung dalam kalimat. Kata-kata informatif yang terkandung pada kalimat dapat mengindikasikan bahwa kalimat tersebut penting. Penelitian ini bertujuan untuk melakukan pembobotan kalimat pada peringkasan multi-dokumen berita dengan pendekatan fitur berita dan informasi gramatikal (NeFGIS). Informasi gramatikal yang dibawa oleh part of speech tagging (POS Tagging) dapat menunjukkan adanya konten informatif. Pembobotan kalimat dengan pendekatan fitur berita dan informasi gramatikal diharapkan mampu memilih kalimat representatif secara lebih baik dan mampu meningkatkan kualitas hasil ringkasan. Pada penelitian ini terdapat 4 tahapan yang dilakukan antara lain seleksi berita, text preprocessing, sentence scoring, dan penyusunan ringkasan. Untuk mengukur hasil ringkasan menggunakan metode evaluasi Recall-Oriented Understudy for Gisting Evaluation (ROUGE) dengan empat varian fungsi yaitu ROUGE-1, ROUGE-2, ROUGE-L, dan ROUGE-SU4. Hasil ringkasan menggunakan metode yang diusulkan (NeFGIS) dibandingkan dengan hasil ringkasan menggunakan metode pembobotan dengan pendekatan fitur berita dan trending issue (NeFTIS). Metode NeFGIS memberikan hasil yang lebih baik dengan peningkatan nilai untuk fungsi recall pada ROUGE-1, ROUGE-2, ROUGE-L, dan ROUGE-SU4 secara berturut-turut adalah 20,37%, 33,33%, 1,85%, 23,14%. News Feature Scoring (NeFS) is a sentence weighting method that used to weight the sentences in document summarization based on news features. There are several news features including word frequency, sentence position, Term Frequency-Inverse Document Frequency (TF-IDF), and sentences resemblance to the title. The NeFS method is able to select important sentences by calculating the frequency of words and measuring the similarity of words between sentences and titles. However, NeFS weighting method is not enough, because the method ignores the informative word in the sentence. The informative words contained in the sentence can indicate that the sentence is important. This study aims to weight the sentence in news multi-document summarization with news feature and grammatical information approach (NeFGIS). Grammatical information carried by part of speech tagging (POS Tagging) can indicate the presence of informative content. Sentence weighting with news features and grammatical information approach is expected to be able to determine sentence representatives better and be able to improve the quality of the summary results. In this study, there are 4 stages that are carried out including news selection, text preprocessing, sentence scoring, and compilation of summaries. Recall-Oriented Understanding for Gisting Evaluation (ROUGE) is used to measure the summary results with four variants of function; ROUGE-1, ROUGE-2, ROUGE-L, and ROUGE-SU4. Summary results using the proposed method (NeFGIS) are compared with summary results using sentence weighting methods with news feature and trending issue approach (NeFTIS). The NeFGIS method provides better results with increased value for recall functions in ROUGE-1, ROUGE-2, ROUGE-L, and ROUGE-SU4 respectively 20.37%, 33.33%, 1.85%, 23.14%.

Unit Pelaksana Teknis Balai Penyuluhan Pertanian (UPT BPP) Sukaraja berupaya untuk meningkatkan kinerja penyuluh pertanian guna meningkatkan kualitas penyuluh, sebab kinerja yang negatif akan membawa perubahan tidak baik terhadap peningkatan hasil pertanian di wilayah binaan UPT BPP Sukaraja. Evaluasi kinerja penyuluh di UPT BPP Sukaraja dilaksanakan setiap tiga bulan dan enam bulan sekali. Selama ini, evaluasi dilakukan secara manual, sehingga kegiatan evaluasi tidak dapat dilaksanakan dengan tepat waktu karena terkendala tenaga kerja yang tidak memadai. Model yang digunakan dalam kajian evaluasi kinerja penyuluh pertanian ini menggunakan motede Promethee (Preference Ranking Organizational Method for Enrichment Evaluation). Metode Promethee dilakukan pertama kali dengan menentukan bobot kualitatif alternatif dari setiap kriteria, menentukan tipe fungsi preferensi, menghitung nilai preferensi antar alternatif, menghitung index preferensi, kemudian menghitung nilai leaving flow, entering flow, dan net flow. Hasil penerapan metode ini menghasilkan komposisi rangking atau peringkat penyuluh pertanian yang baik, yaitu penyuluh dengan inisial Sd dengan nilai net flow 1,31106 dan yang membutuhkan pembinaan adalah penyuluh dengan inisial Sj dan Dm dengan nilai net flow -0,81665 dan -0,51111. Technical Implementation Unit of the Agricultural Extension Center (UPT BPP) Sukaraja supports to improve the performance of extension agents in order to improve the quality of extension agents, because negative performance will bring changes in bad changes to the increase in agricultural yields in the target areas of UPT BPP Sukaraja. The performance evaluation of instructors at UPT BPP Sukaraja is conducted every three months and every six months. So far, evaluations have been carried out manually, so that evaluation activities cannot be carried out in a timely manner because of constraints on inadequate labor. In order to evaluate instructor's performance, a model namely Promethe (Preference Ranking Organizational Method for Enrichment Evaluation) was used. It was started with identifying certain alternatives and types of preferences function, followed by determining preferences value between alternatives. Afterwards, preferences index, leaving and entering value, and net flows should be calculated. The method produces good ranks of agricultural instructors, with initials Sd and a net flow value of 1.31106. Furthermore, it produces extension agents on initials Sj and Dm with Net flow values of -0.81665 and -0.51111.

pemilihan tenaga kesehatan teladan
Sistem Pendukung Keputusan
selection of exemplary health workers
SPK
Pemilihan tenaga kesehatan teladan merupakan kegiatan rutin setiap tahun oleh Dinas kesehatan yang bertujuan untuk memberi penghargaan kepada mereka yang sudah mengabdikan diri di Puskesmas. Penilaian yang masih manual dianggap kurang produktif, subjektif, dan kurang efisien. Sistem Pendukung Keputusan (SPK) diperlukan untuk memudahkan pekerjaan tim juri dalam memutuskan petugas kesehatan teladan secara objektif, profesional dan transparan. Sistem yang dibangun ini berbasis stand-alone, dan dapat dijadikan alternatif terbaik untuk daerah yang akses internetnya belum cukup memadai. Penelitian ini dilakukan melalui literature review dan wawancara langsung pada tim penilai tenaga kesehatan. Model yang digunakan adalah metode Multi Attribute Utility Theory (MAUT). Hasil metode MAUT dipilih karena tidak memiliki nilai cost dan benefit dalam menentukan keputusan. Penelitian ini telah menghasilkan rekomendasi untuk pemilihan tenaga kesehatan teladan dengan hasil akurasi sebesar 86,67%. The selection of exemplary medical personnel is an annual event held by the Public Health office which aims to reward those who have already served in the community health centers. Manual evaluation method is considered to be less productive, subjective and less efficient. Decision Support System (DSS) is needed to facilitate the work of the jury team in determining exemplary health personnel to be more objective, professional and transparent. The system was built stand alone made as the best alternative for regions where internet access is not sufficient. This research was carried out through literature review and direct interviews with the health personnel assessment team. The model that was used in this research is Multi Attribute Utility Theory method. MAUT was used because it did not have the value of cost and benefit in determining decisions. This study has produced recommendations for the selection of exemplary health personnel with an accuracy of 86.67%.

Keberhasilan layanan website Universitas Tadulako sampai saat ini belum diketahui, karena belum pernah dilakukan pengukuran sejak diimplementasikan. Tingkat keberhasilan layanan website Universitas Tadulako dapat dilihat dari kesesuaian antara persepsi dan harapan pengguna website. Penelitian ini dilakukan dengan tujuan untuk mengetahui perbedaan antara persepsi aktual dan harapan ideal mahasiswa terhadap kualitas layanan website Universitas Tadulako yang diukur berdasarkan dimensi kualitas WebQual 4.0. Data dikumpulkan dengan menggunakan kuesioner dengan teknik Simple Random Sampling. Data kemudian dianalisis dengan menggunakan teknik Analisis Perbedaan (uji beda t) dan Importance Performance Analysis (IPA). Hasil penelitian membuktikan bahwa terdapat perbedaan (gap) antara persepsi aktual dan harapan ideal mahasiswa pada masing-masing dimensi kualitas website, di mana nilai persepsi lebih kecil dibandingkan dengan harapan mahasiswa. Gap paling kecil terletak pada dimensi kegunaan (usability) dengan tingkat kesesuaian sebesar 85% yang mengindikasikan bahwa layanan website Universitas Tadulako cukup berhasil pada kegunaan wesbite. Gap paling besar terletak pada dimensi kualitas interaksi layanan dengan tingkat kesesuaian sebesar 73,52% yang mengindikasikan bahwa layanan website Universitas Tadulako yang belum memenuhi harapan ideal mahasiswa, terutama dari kualitas interaksi layanan website. Hasil penelitian dapat menjadi acuan bagi pihak manajemen website untuk mengembangkan website yang lebih baik agar memenuhi harapan pengguna. The success of Tadulako University website service is still unknown because it has never been measured since it was implemented. The success rate of Tadulako University website service can be seen from the fitness between the perception and expectations of website users. This research was conducted to find out thegap value between student’s actual perception and ideal expectations of Tadulako University website services quality which is measured by WebQual 4.0 dimensions. Data was collected using a questionnaire with simple random sampling technique. The collected data were analyzed using differences analysis and Importance Performance Analysis (IPA). The results showed that there are differences (gap) between student’s actual perception and ideal expectations at each of dimension of website quality, where the perception’s value is smaller than the expectations. The smallest gap lies in the usability dimension with a suitability level of 85% that indicates Tadulako University website services quality quite successful on usability. The biggest gap lies in the service interaction quality dimension with a suitability level of 73.52% that indicates Tadulako University website services quality has not met the student’s ideal expectations especially from service interaction quality.

Faktor-faktor kematangan implementasi e-government yang berorientasi kepada masyarakat
Wulansari, Anita
Inayati, Immah
citizen-centric
e-government
grounded theory
maturity measurement
penilaian kematangan
Surabaya Single Window
Masyarakat merupakan pemegang kepentingan utama dalam penyelenggaraan e-government. Namun demikian, dalam konteks penelitian e-government, orientasi terhadap masyarakat masih belum banyak dieksploitasi karena sebagian besar proyek e-government hanya mentransformasi layanan dan informasi yang semula masih tradisional menjadi menggunakan teknologi. Model-model penilaian kematangan e-government yang sudah ada pun sebagian besar hanya mengukur kemampuan teknologi e-government. Oleh karena itu, perlu dikembangkan penilaian kematangan e-government yang menempatkan masyarakat sebagai fokus utamanya. Faktor-faktor kematangan didapatkan melalui pendekatan penelitian kualitatif grounded theory. Objek penelitian adalah layanan e-health dan Surabaya Single Window (SSW). Hasil penelitian menunjukkan ada tiga faktor yang diukur dalam penentuan kematangan e-government yang berorientasi kepada masyarakat, yaitu lembaga, interaksi, dan layanan online. Model ini diharapkan dapat digunakan sebagai alternatif alat penilaian implementasi e-government yang lebih komprehensif karena mengukur dari tiga sisi, yaitu lembaga pemerintah, interaksi pegawai pemerintah dengan masyarakat, dan layanan e-government yang disediakan. Society is responsible for implementing e-government. Nevertheless, the context of research on e-government, orientation to society has not been exploited due to numerous projects which are only transformed service and information from previous traditional users to technology. Most of existing models of e-government was only used to determine the ability of the government. Therefore, it is necessary to develop maturity assessment of e-government placing society as major focus. Its factors are derivable from qualitative research approach of ground theory. The objects of research were e-health and Surabaya Single Window (SSW) services. The results of the study indicate that there were three factors measured in determining maturity of e-government oriented to society; the factors are institution, interaction and online services. This model could be used as more comprehensive alternative to assessment tool of e-government implementation because it measured three aspects, namely, institution, interaction of employees and provided e-government services.

Bot spammer merupakan penyalahgunaan user dalam menggunakan Twitter untuk menyebarkan pesan spam sesuai dengan keinginan user. Tujuan spam mencapai trending topik yang ingin dibuatnya. Penelitian ini mengusulkan deteksi bot spammer pada Twitter berbasis Time Interval Entropy dan global vectors for word representations (Glove). Time Interval Entropy digunakan untuk mengklasifikasi akun bot berdasarkan deret waktu pembuatan tweet. Glove digunakan untuk melihat co-occurrence kata tweet yang disertai Hashtag untuk proses klasifikasi menggunakan Convolutional Neural Network (CNN). Penelitian ini menggunakan data API Twitter dari 18 akun bot dan 14 akun legitimasi dengan 1.000 tweet per akunnya. Hasil terbaik recall, precision, dan f-measure yang didapatkan yaitu 100%; 100%, dan 100%. Hal ini membuktikan bahwa Glove dan Time Interval Entropy sukses mendeteksi bot spammer dengan sangat baik. Hashtag memiliki pengaruh untuk meningkatkan deteksi bot spammer. Spam spammers are users' misuse of using Twitter to spread spam messages in accordance with user wishes. The purpose of spam is to reach the required trending topic. This study proposes detection of bot spammers on Twitter based on Time Interval Entropy and global vectors for word representations (Glove). Time Interval Entropy is used to classify bot accounts based on the tweet's time series, while glove views the co-occurrence of tweet words with Hashtags for classification processes using the Convolutional Neural Network (CNN). This study uses Twitter API data from 18 bot accounts and 14 legitimacy accounts with 1000 tweets per account. The best results of recall, precision, and f-measure were 100%respectively. This proves that Glove and Time Interval Entropy successfully detects spams, with Hash tags able to increase the detection of bot spammers.

Query Expansion menggunakan Word Embedding dan Pseudo Relevance Feedback
Tanuwijaya, Evan
Adam, Safri
Anggris, Mohammad Fatoni
Arifin, Agus Zainal
Pseudo Relevant Feedback
Query Expansion
Word Embedding
Kata kunci merupakan hal terpenting dalam mencari sebuah informasi. Penggunaan kata kunci yang tepat menghasilkan informasi yang relevan. Saat penggunaannya sebagai query, pengguna menggunakan bahasa yang alami, sehingga terdapat kata di luar dokumen jawaban yang telah disiapkan oleh sistem. Sistem tidak dapat memproses bahasa alami secara langsung yang dimasukkan oleh pengguna, sehingga diperlukan proses untuk mengolah kata-kata tersebut dengan mengekspansi setiap kata yang dimasukkan pengguna yang dikenal dengan Query Expansion (QE). Metode QE pada penelitian ini menggunakan Word Embedding karena hasil dari Word Embedding dapat memberikan kata-kata yang sering muncul bersama dengan kata-kata dalam query. Hasil dari word embedding dipakai sebagai masukan pada pseudo relevance feedback untuk diperkaya berdasarkan dokumen jawaban yang telah ada. Metode QE diterapkan dan diuji coba pada aplikasi chatbot. Hasil dari uji coba metode QE yang diterapkan pada chatbot didapatkan nilai recall, precision, dan F-measure masing-masing 100%; 70% dan 82,35 %. Hasil tersebut meningkat 1,49% daripada chatbot tanpa menggunakan QE yang pernah dilakukan sebelumnya yang hanya meraih akurasi sebesar 68,51%. Berdasarkan hasil pengukuran tersebut, QE menggunakan word embedding dan pseudo relevance feedback pada chatbot dapat mengatasi query masukan dari pengguna yang ambigu dan alami, sehingga dapat memberikan jawaban yang relevan kepada pengguna. Keywords are the most important words and phrases used to obtain relevant information on content. Although users make use of natural languages, keywords are processed as queries by the system due to its inability to process. The language directly entered by the user is known as query expansion (QE). The proposed QE in this research uses word embedding owing to its ability to provide words that often appear along with those in the query. The results are used as inputs to the pseudo relevance feedback to be enriched based on the existing documents. This method is also applied to the chatbot application and precision, and F-measure values of the results obtained were 100%, 70%, 82.35% respectively. The results are 1.49% better than chatbot without using QE with 68.51% accuracy. Based on the results of these measurements, QE using word embedding and pseudo which gave relevance feedback in chatbots can resolve ambiguous and natural user’s input queries thereby enabling the system retrieve relevant answers.

Arifin, Agus Zainal
ambiguitas
ambiguity
chatbot
Cross Language
machine translation
mesin translasi
POS Tagging
Sistem Information Retrieval (IR) maupun chatbot semakin banyak dikembangkan. Salah satu bagian yang banyak diteliti adalah cross language. Masalah pada pengembangan cross language yaitu terjadinya kesalahan pada hasil terjemahan mesin translasi yang memberikan arti tidak sesuai dengan bahasa natural, sehingga pengguna tidak mendapatkan jawaban yang semestinya, bahkan tidak jarang pula pengguna tidak menemukan jawaban. Penelitian ini mengusulkan skema baru mesin translasi yang bertujuan meningkatkan performa dalam masalah ambiguitas. Mesin translasi bekerja dengan cek kebenaran kata kunci, kemudian melakukan Part-of-Speech (POS) Tagging pada kata benda (noun). Kemudian, setiap kata benda yang terdeteksi akan dicari sinonimnya. Lalu, sinonim yang didapatkan akan ditambahkan dan menjadi alternatif kueri baru. Kueri yang mempunyai nilai confident tertinggi diasumsikan sebagai kueri yang paling sesuai. Pada hasil yang didapatkan setelah dilakukan uji coba, melalui penambahan metode yang kami usulkan pada machine translation, dapat meningkatkan akurasi chatbot dibandingkan tanpa menggunakan skema yang diusulkan. Hasil akurasi bertambah 5%, dari yang semula 73% menjadi 77%. Information retrieval and chatbot systems are increasingly being developed with its language part mostly studied. However, the problem associated with its development is the occurrence of errors in the translation machine resulting in inaccurate answers not in accordance with the natural language, thereby providing users with wrong answers. This study proposes a new translation machine scheme that aims to improve performance while translating ambiguous terms. Translation machines functions by checking the correctness of keywords, and carrying out Part-of-Speech (POS) Tagging on nouns (noun). The synonyms of any detected noun are searched for and obtained added to become alternative new queries. Those with the highest confident value are assumed to be the most appropriate. The results obtained after testing, through the addition of the method proposed in machine translation, can improve the accuracy of the chatbot compared to not using the proposed scheme. The results of the accuracy increased from the original 73% to 77%.

Kebergunaan (usability) adalah salah satu faktor penting dalam sebuah aplikasi. Saat ini, Dinas Pemberdayaan Masyarakat Desa (PMD) Kabupaten Ogan Ilir telah menyediakan aplikasi administrasi penduduk desa sebagai usaha untuk mencapai tertib administrasi, terutama berkaitan dengan data penduduk. Untuk itu, penelitian ini mengusulkan evaluasi tingkat kebergunaan aplikasi dengan teknik System Usability Scale untuk melihat kelayakan aplikasi yang disediakan untuk digunakan. System usability scale memiliki sepuluh pernyataan sebagai instrumen evaluasi dan tiga indikator penilaian, yaitu acceptability, grade scale, dan adjective rating. Masing-masing pernyataan menjadi indikator untuk melihat tingkat kebergunaan aplikasi. Hasil evaluasi menunjukkan bahwa mayoritas responden dapat memanfaatkan aplikasi dengan baik yang dibuktikan dari nilai rerata setiap pernyataan > 3. Selain itu, aplikasi administrasi penduduk desa juga dapat dikategorikan sebagai excellent serta berada pada grade B dengan nilai akhir 88,5. Usability is one of the most important factors of an application. Currently, the PMD Office of Ogan Ilir District has provided villages with administrative applications as an effort to achieve administration order and boost its effectiveness while analyzing population data. This research evaluates the usability and feasibility levels of applications using the scale system technique. This consists of ten statements as an evaluation instrument with acceptability, grade scale, and adjective rating used as test indicators. The evaluation results shows, that majority of respondents argue that the application is easily proven from the mean score of each statement > 3. In addition, the village administration application is in very good category and it is in grade B with a final score of 88.5.

traditional musical instruments
Dengan berkembangnya teknologi, kesadaran akan pentingnya alat musik tradisional menjadi berkurang. Demikian juga dengan alat musik tradisional Bangka yang mulai kehilangan popularitasnya. Kondisi saat ini, para remaja di Bangka kebanyakan tidak dapat memainkan alat musik tradisionalnya. Begitu juga dengan anak-anak yang belum mengetahui dan bahkan tidak mengenal alat musik tradisional daerah mereka. Jika kondisi ini dibiarkan, dikhawatirkan keberadaan alat musik tradisional Bangka akan hilang, begitu juga dengan sumber daya manusia yang dapat memainkannya. Untuk menghindari hal tersebut, dibuatlah aplikasi pengenalan alat musik tradisional Bangka menggunakan Augmented Reality (AR). AR dipilih karena dapat memberikan gambaran alat musik secara real time dalam bentuk 3D sesuai dengan pergerakan kamera smartphone yang dinamis. Empat objek 3D alat musik yakni dambus, rebab, rebanatamborin, dan gong yang dibuat menggunakan Autodesk Maya. AR yang dibangun menggunakan metode berbasis marker. Metode ini dipilih agar lebih mudah digunakan oleh pengguna yang mayoritasnya adalah anak-anak. Selain itu, kelebihan metode ini memiliki tingkat akurasi posisi yang sangat tinggi. Unity sebagai engine untuk penerapan AR 3D modelling pada sistem Android dan Vuforia SDK sebagai engine pembentuk marker augmented reality. Pengujian fungsional memiliki hasil 100% dengan sistem yang berjalan baik. Hasil pengujian kinerja deteksi objek AR berdasarkan intensitas cahaya diketahui bahwa smartphone yang memiliki dua kamera di bagian belakang dapat mendeteksi objek dengan intensitas cahaya 0 Lux pada malam hari dengan kondisi gelap, sedangkan yang hanya memiliki satu kamera tidak dapat mendeteksi objek. Pengujian warna marker mendapatkan hasil modifikasi warna marker pink, kuning, dan hitam yang masih memungkinkan untuk pendeteksian objek, walaupun objek yang tampil tidak stabil. Dari pengujian kertas marker diketahui bahwa jenis kertas tidak berpengaruh terhadap pendeteksian objek. Pengujian beta dilakukan dengan cara membagikan kuesioner terkait pengalaman pengguna dalam penggunaan sistem. Hasil survei diketahui pengguna merasa sangat setuju dengan nilai sebesar 80%, bahwa penggunaan sistem dapat membantu mereka dalam mengenal alat musik tradisional Bangka. With the incessant development of technology, awareness on the importance of traditional musical instruments has declined. Similarly, teenagers living in Bangka no longer play their traditional musical instruments, and children are not exposed to their cultural heritage. However, if this continues, it is feared that the existence of traditional Bangka musical instruments will soon go extinct. To avoid this, researchers have proposed an application to identify this media using Augmented Reality (AR). This technique was chosen due to its ability to provide visuals of musical instruments in real time using 3D models in accordance with the dynamic movement of smartphone cameras. This comprises of four 3D objects namely dambus, rebab, rebanatamborin, and gong, which were designed and developed using Autodesk Maya. AR is built using marker-based methods, which was chosen for easy use because majority of its users are children, and its high level of accuracy. Unity was utilized as an engine for its implementation in the Android system, and Vuforia SDK as augmented reality marker-builder engine. Functional testing showed 100% results which means that the system is running well. From the results of the AR object detection performance test based on light intensity it is known that a smartphone with two cameras in the backside has the ability to detect objects with a light intensity of 0 Lux in dark rooms, while the other smartphone with one camera failed to detect the objects. Color testing obtained a modification of marker colors comprising of pink, yellow, and black which are still able to detect objects, although not stable. The paper test marker has no effect on object detection. Beta testing questionnaires were used to obtain information related to user experience. From the survey results, it is known that users strongly agree (80%) that the use of the system helps them to recognize traditional Bangka musical instruments.

Soal cerita berperan penting untuk kemajuan pengembangan kecerdasan buatan. Hal ini karena penyelesaian soal cerita melibatkan pengembangan sebuah sistem yang mampu memahami bahasa alami. Pembentukan sistem penyelesaian soal memerlukan mekanisme untuk mendekomposisikan teks soal ke segmen-segmen teks untuk diterjemahkan ke jenis operasi hitung. Segmen-segmen tersebut ditentukan melalui proses parsing semantik struktur soal agar menghasilkan segmen-segmen yang maknanya menunjuk operasi hitung. Sejumlah metode usulan saat ini sesuai untuk diterapkan pada soal cerita berbahasa Inggris dan belum diterapkan pada soal cerita berbahasa Indonesia. Dampaknya adalah segmen-segmen yang dihasilkan belum tentu menghasilkan urutan pengerjaan operasi yang sesuai makna cerita. Penelitian ini mengusulkan penggunaaan Recursive Neural Network (RNN) sebagai parser struktur semantik soal cerita berbahasa Indonesia. Pengujian parser struktur semantik soal dilakukan terhadap soal-soal yang berasal dari Buku Sekolah Elektronik (BSE) Sekolah Dasar (SD) dari Pusat Perbukuan Kementerian Pendidikan dan Kebudayaan. Hasil pengujian menunjukkan akurasi akhir sebesar 86,4%. Math word problems play an important role for the development of artificial intelligent. This is because solving word problems involves the development of a system that can understand natural language. Designing a system for solving math word problems requires a mechanism for decomposing a text into segments of text to be translated into math operation. The segments are categorized through the process of parsing the semantic structure of the word problems to obtain segments whose meanings refer to math operation. A number of current proposed methods are suitable to be applied to English math word problems and have never been applied to Indonesian math word problems. The impact is that the segments produced are not necessarily in line with the sequences of operations appropriate with the meaning of the story. This study proposed the use of Recursive Neural Network (RNN) as a parser of semantic structure of Indonesian math word problems. The testing of the parser was carried out on the math word problems taken from the Elementary School’s Electronic School Book (BSE) published by the Book Center of the Ministry of Education and Culture. The result of the testing showed that the final accuracy was 86.4%.

Online news portals are currently one of the fastest sources of information used by people. Its impact is due to the credibility of the news produced by actors from the media industry, which is sometimes questioned. However, one of the problems associated with this medium used to obtain information is clickbait. This technique aims to attract users to click hyperbolic headlines with content that often disappoints the reader. This study was, therefore, conducted to determine: 1) existing dataset available. 2) The method used in clickbait detection which consists of data preprocessing, analysis of features, and classification. 3) Difference steps from the method used.

Twitter
Twitter is now considered as one of the fastest and most popular communication media and is often used to track current events or news. Many tweets tend to contain semantically identical information. When following an activity or news, sometimes in tweeting people do it in groups. Therefore, it is necessary to have a useful technique for grouping users based on the tweets similarities. In this study, cosine similarity method is used to examine the similarity of tweets between accounts, and a graph-based approach is proposed to detect communities. Graphs are first depicted from similarities between tweets and next community detection techniques are applied in graphs to group accounts that have similar tweets. The reason for using these two methods is that compared to other methods, the accuracy of cosine similarity is higher while Louvain can result a better modularity. From this research, it was concluded that cosine similarity and Louvain algorithm could be used in community detection on social media.

Gita Persada Butterfly Park is the only breeding of engineered in situ butterflies in Indonesia. It is located in Lampung and has approximately 211 species of breeding butterflies. Each species of Butterflies has a different texture on its wings. The Limited ability of the human eye to distinguishing typical textures on butterfly species is the reason for conducting a research on butterfly identification based on pattern recognition. The dataset consists of 600 images of butterfly’s upper wing from six species: Centhosia penthesilea, Papilio memnon, Papilio nephelus, Pachliopta aristolochiae, Papilio peranthus and Troides helena. The pre-processing stage is conducted using scaling, segmentation and grayscale methods. The GLCM method is used to recognize the characteristics of butterfly images using pixel distance and Angular direction 0o, 45o, 90o and 135o. The features used is angular second moment, contrast, homogeneity and correlation. KNN classification method in this study uses k values1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21 and 23 based on the Rule of Thumb. The result of this study indicate that Centhosia penthesilea and Papilio nephelus classes can be classified properly compared to the other 4 classes and require a classification time of 2 seconds at each angular orientation. The highest accuracy is 91.1% with a value of in the angle of 90o and error rate8.9%. Classification error occured because the value of the test data features is more dominant with the value of the training image features in different classes than the supposed class. Another reason is because of imperfect test data.

DeLone and McLean model
end-user computing
satisfaction
Partial Least Squares
This research was based on the modification of the DeLone and McLean information systems models by adding end-user computing satisfaction variables to determine the success factors for e-government systems. This model was adopted due to the aim of this study to investigate the factors responsible for the successful implementation of e-government by bringing it closer to public value. However, while the DeLone and McLean models focus more on the information system approach, the model proposed was on the premise that system quality (SQ), information quality (IQ), content (CO) and format (FO) are determinants of e-government system user satisfaction. Furthermore, the net benefits through a five-dimensional public value determinants were used to evaluate e-government websites from a community perspective. Responses from 150 communities were analyzed by smart PLS 3.0 using structural equation models to examine the relationship between the constructs of the proposed model. This study contributes to the research gap in adopting DeLone and McLean's model in the e-government due to the limitation in its validation for different contexts. The results support the effect of content variables on user satisfaction and simultaneously prove that it is possible to explain net benefits, with an r-squared value of 69.1%, using the variables in the proposed model. The five dimensions of public value adopted all proved to have a positive influence with a confidence level of 95%. The level of construct significance identified is able to help in the formulation of strategies to improve e-government services.

Genetic Algorithm
multi-parent crossover
order crossover
soft constraint
A crossover operator is one of the critical procedures in genetic algorithms. It creates a new chromosome from the mating result to an extensive search space. In the course timetabling problem, the quality of the solution is evaluated based on the hard and soft constraints. The hard constraints need to be satisfied without violation while the soft constraints allow violation. In this research, a multi-parent crossover mechanism is used to modify the classical crossover and minimize the violation of soft constraints, in order to produce the right solution. Multi-parent order crossover mechanism tends to produce better chromosome and also prevent the genetic algorithm from being trapped in a local optimum. The experiment with 21 datasets shows that the multi-parent order crossover mechanism provides a better performance and fitness value than the classical with a zero fitness value or no violation occurred. It is noteworthy that the proposed method is effective to produce available course timetabling.

Fast Hybrid Classification
k-NN
video
Nowadays, the need for face recognition is no longer include images only but also videos. However, there are some challenges associated with the addition of this new technique such as how to determine the right pre-processing, feature extraction, and classification methods to obtain excellent performance. Although nowadays the k-Nearest Neighbor (k-NN) is widely used, high computational costs due to numerous features of the dataset and large amount of training data makes adequate processing difficult. Several studies have been conducted to improve the performance of k-NN using the FHC (Fast Hybrid Classification) method by optimizing the local k values. One of the disadvantages of the FHC Method is that the k value used is still in the default form. Therefore, this research proposes the use of k-NN value optimization methods in FHC, thereby, increasing its accuracy. The Fast Hybrid Classification which combines the k-means clustering with k-NN, groups the training data into several prototypes called TLDS (Two Level Data Structure). Furthermore, two classification levels are applied to label test data, with the first used to determine the n number of prototypes with the same class in the test data. The second classification using the optimized k value in the k-NN method, is employed to sharpen the accuracy, when the same number of prototypes does not reach n. The evaluation results show that this method provides 86% accuracy and time performance of 3.3 seconds.

Combination of Synthetic Minority Oversampling Technique (SMOTE) and Backpropagation Neural Network to handle imbalanced class in predicting the use of contraceptive implants Kegagalan akibat pemakaian alat kontrasepsi implan merupakan terjadinya kehamilan pada wanita saat menggunakan alat kontrasepsi secara benar. Kegagalan pemakaian kontrasepsi implan tahun 2018 secara nasional sejumlah 1.852 pengguna atau 4% dari 41.947 pengguna. Rasio angka kegagalan dan keberhasilan pemakaian kontrasepsi implan yang cenderung tidak seimbang (imbalance class) membuatnya sulit diprediksi. Ketidakseimbangan data terjadi jika jumlah data suatu kelas lebih banyak dari data lain. Kelas mayor merupakan jumlah data yang lebih banyak, sedangkan kelas minor jumlahnya lebih sedikit. Algoritma klasifikasi akan mengalami penurunan performa jika menghadapi kelas yang tidak seimbang. Synthetic Minority Oversampling Technique (SMOTE) digunakan untuk menyeimbangkan data kegagalan pemakaian kontrasepsi implan. SMOTE menghasilkan akurasi yang baik dan efektif daripada metode oversampling lainnya dalam menangani imbalance class karena mengurangi overfitting. Data yang sudah seimbang kemudian diprediksi dengan Neural Network Backpropagation. Sistem prediksi ini digunakan untuk mendeteksi apakah seorang wanita mengalami kehamilan atau tidak jika menggunakan kontrasepsi implan. Penelitian ini menggunakan 300 data, terdiri dari 285 data mayor (tidak hamil) dan 15 data minor (hamil). Dari 300 data dibagi menjadi dua bagian, 270 data latih dan 30 data uji. Dari 270 data latih, terdapat 13 data latih minor dan 257 data latih mayor. Data latih minor pada data latih diduplikasi sebanyak data pada kelas mayor sehingga jumlah data latih menjadi 514, terdiri dari 257 data mayor, 13 data minor asli, dan 244 data minor buatan. Sistem prediksi menghasilkan nilai akurasi sebesar 96,1% pada epoch ke-500 dan 1.000. Implementasi kombinasi SMOTE dan Neural Network Backpropagation terbukti mampu memprediksi pada imbalance class dengan hasil prediksi yang baik. The failed contraceptive implant is one of the sources of unintended pregnancy in women. The number of users experiencing contraceptive-implant failure in 2018 was 1,852 nationally or 4% out of 41,947 users. The ratio between failure and success rates of contraceptive implant, which tended to be unbalanced (imbalance class), made it difficult to predict. Imbalance class will occur if the amount of data in one class is bigger than that in other classes. Major classes represent a bigger amount of data, while minor classes are smaller ones. The imbalance class will decrease the performance of the classification algorithm. The Synthetic Minority Oversampling Technique (SMOTE) was used to balance the data of the contraceptive implant failures. SMOTE resulted in better and more effective accuracy than other oversampling methods in handling the imbalance class because it reduced overfitting. The balanced data were then predicted using backpropagation neural networks. The prediction system was used to detect if a woman using a contraceptive implant was pregnant or not. This study used 300 data, consisting of 285 major data (not pregnant) and 15 minor data (pregnant). Of 300 data, two groups of data were formed: 270 training data and 30 testing data. Of 270 training data, 13 were minor training data and 257 were major training data. The minor training data in the training data were duplicated as much as the number of data in major classes so that the total training data became 514, consisting of 257 major data, 13 original minor data, and 244 artificial minor data. The prediction system resulted in an accuracy of 96.1% on the 500th and 1,000th epochs. The combination of SMOTE and Backpropagation Neural Network was proven to be able to make a good prediction result in imbalance class.

Management of jpeg/exif file fingerprint with Brute Force string matching algorithm and Hash Function SHA256Metode pengamanan berkas gambar jpeg/exif saat ini hanya mencakup aspek pencegahan, belum pada aspek deteksi integritas data. Digital Signature Algorithm (DSA) adalah metode kriptografi yang digunakan untuk memverifikasi integritas data menggunakan hash value. SHA256 merupakan hash function yang menghasilkan 256-bit hash value yang berfungsi sebagai file fingerprint. Penelitian ini bertujuan untuk menyusun file fingerprint dari berkas jpeg/exif menggunakan SHA256 dan algoritma Brute Force string matching untuk verifikasi integritas berkas jpeg/exif. Penelitian dilakukan dalam lima tahap. Tahap pertama adalah identifikasi struktur berkas jpeg/exif. Tahap kedua adalah akuisisi konten segmen. Tahap ketiga penghitungan hash value. Tahap keempat adalah eksperimen modifikasi berkas jpeg/exif. Tahap kelima adalah pemilihan elemen dan penyusunan file fingerprint. Hasil penelitian menunjukkan sebuah jpeg/exif file fingerprint tersusun atas tiga hash value. SOI (Start of Image) segment hash value digunakan untuk mendeteksi terjadinya modifikasi berkas dalam bentuk perubahan tipe berkas dan penambahan objek pada konten gambar. Hash value segmen APP1 digunakan untuk mendeteksi modifikasi pada metadata berkas. Hash value segmen SOF0 digunakan untuk mendeteksi gambar yang dimodifikasi dengan teknik recoloring, resizing, dan cropping. The method of securing jpeg/exif image files currently has covered only the prevention aspect instead of the data integrity detection aspect. Digital Signature Algorithm is a cryptographic method used to verify the data integrity using hash value. SHA256 is a hash function that produces a 256-bit hash value functioning as a fingerprint file. This study aimed at compiling fingerprint files from jpeg/exif files using SHA256 and Brute Force string matching algorithm to verify the integrity of jpeg/exif files. The research was conducted in five steps. The first step was identifying the jpeg/exif file structure. The second step was the acquisition of the segment content. The third step was calculating the hash value. The fourth step was the jpeg/exif file modification experiment. The fifth step was the selection of elements and compilation of fingerprint files. The obtained results showed a jpeg/exif fingerprint file which was compiled in three hash values. The hash value of SOI segment was used to detect the occurrence of file modification in the form of file type changing and object addition on the image content. The hash value of APP1 segment was used to detect the metadata file modification. The hash value of SOF0 segment was used to detect the images modified by recoloring, resizing, and cropping techniques.

Development of a grid-based clustering mechanism to improve LEACH performance in the Wireless Sensor Network environmentLow Energy Adaptive Clustering Hierarchy (LEACH) merupakan algoritma routing pada Wireless Sensor Network (WSN) berbasis cluster. LEACH memilih sebuah node sebagai cluster head (CH) yang tugasnya untuk melakukan komunikasi dengan sink maupun guna mengumpulkan data dari member node. Persebaran CH pada LEACH yang dikatakan acak, kadang mengalami masalah mengingat rumus probabilitas pada tiap round. Hal ini akan menyebabkan CH yang terpilih bisa berada di tepi area, juga terjadinya pemborosan energi karena jalur yang terbentuk akan menjadi panjang. Oleh karena itu, kami ingin mengembangkan routing protocol G-LEACH menggunakan teknik merge CH dalam suatu area (grid) disertai beberapa parameter yang relevan, seperti posisi node, node dengan sisa energi terbesar, dan jarak yang dihitung dalam tiga jarak yaitu jarak node menuju cluster center, jarak node menuju merge CH, dan jarak merge CH menuju sink. Hasil pengujian menunjukan bahwa dengan menggabungkan cluster (merge CH) pada transmisi data menuju sink pada protokol G-LEACH dapat menghasilkan masa hidup jaringan yang lebih lama pada seluruh operasi node, energi yang dibutuhkan pada semua node lebih rendah, dan lebih banyak paket data yang dikirim dan diterima oleh sink. Low Energy Adaptive Clustering Hierarchy (LEACH) is a routing algorithm in a cluster-based Wireless Sensor Network (WSN). LEACH selects a node as a cluster head (CH) whose responsibility is for communicating with sinks and collect data from the node members. The distribution of CH on LEACH, which is basically random, sometimes has a problem in remembering the probability formula on each round. This may make the selected CH on the edge of the area as well as generate energy waste because the pathway formed will be lengthy. Therefore, we would like to develop the G-LEACH routing protocol using a merge CH technique in one area (grid) with several relevant parameters, such as the position of the node, the node with the largest remaining energy, and the distance calculated in three distances: the distance of the node to the clustercenter, the distance of the node to the merge CH, and the distance of the merge CH to the sink. The test result showed that combining clusters (merge CH) in the data transmission to the sink in the G-LEACH protocol could produce a longer network life on all node operations, lower energy required for all nodes, and more data package sent and received by the sink.

ATMSG model
Context-agnostic
Educational games
Platformer games
Educational games are increasingly popular and successful in facilitating various subjects and educational topics. Developing the games are often costly as the developers need to develop specific game content to facilitate each different educational content. One solution to the cost problem is the context-agnostic approach, which allows a game to facilitate educational contents of different subjects or educational topics with zero or minimal modifications to its game content. However, researches on the approach are still scarce, including those aimed at examining real-world applications of the approach. This case study was intended to fill the research gap by examining the application of a context-agnostic educational platformer game in a higher education scenario. The game was used to present educational contents of binary number system and ASCII codes, where both are taught in Informatics Engineering Department. The game was context-agnostic because it was able to flexibly assign educational content elements to various objects in its gameplay. Activity Theory-based Model of Serious Games (ATMSG) was used to guide the design of our educational game. The experiment was conducted with the participation of 60 first-year students of Informatics Engineering Department. The results show that the game can facilitate a more fun and engaging class session for the two educational topics without requiring any changes to the game content. The implication of the results and the implementation complexity of the context-agnostic approach are also discussed.

Implementation of the user-centered design (UCD) method for designing web marketplace of qurban cattle sales in Indonesia
Rahmawati, Endra
designing web marketplace
user-centered design
user experience design
user interface design
usability testing
This study aims to create a user interface design for the designing web marketplace of qurban cattle sales in East Java, Indonesia. The word qurban referred as the qurban animal slaughtered during the Eid al-Adha, especially cow. The qurban web market can help breeders and customers in the process of selling cattle directly without limited territory. This is because the process of selling qurban cows is still done traditionally by ordering directly by phone and coming directly to the cattle pen for the selection of qurban animals desired by consumers. To deal with these problems, an alternative solution is needed that can create a Web Marketplace interface design that is designed using the User-Centered Design (UCD) method, focusing on the user's primary needs. This method was chosen because it focuses on the user's goals, characteristics, and workflow in the design process. How the system can be understood and used by users is a top priority in this web design and involves users in designing the marketplace web interface. Therefore it is very suitable for designing a website that is simple and easy to use. The design of the web marketplace of qurban cattle sales has four main features which are promotion of qurban cattle, online qurban cattle bookigs (direct purchases or livestock care services), payment confirmation, and qurban cattle contributions for collective purchases or in groups. The results of the System Usability Scale (SUS) test distributed to 30 respondents obtained a value of 79.3 which indicates that the qurban web marketplace design can be accepted by users and can be classified as good design.

Forest and land fires are national and international problems. The frequency of fires in one of Indonesia's provinces, Riau, is a significant problem. Knowing where to repair the burn is essential to prevent more massive fires. Fires occur because of a fire triangle, namely fuel, oxygen, and heat. The third factor can be seen through remote sensing. Using the Landsat-8 satellite, named the Enhanced Vegetation Index (EVI) variable, Normalized Burn Area (NBR), Normal Difference Humidity Index (NDMI), Normal Difference Difference Vegetation Index (NDVI), Soil Adapted Vegetation Index (SAVI), and Soil Surface Temperature (LST). DBSCAN, as a grouping algorithm that can group the data into several groups based on data density. This is used because of the density of existing fire data, according to the character of this algorithm. The selected cluster is the best cluster that uses Silhouette Coefficients, eps, and minutes value extracted from each variable, so there is no noise in the resulting cluster. The result is more than 0, and the highest is the best cluster result. There are 5 clusters formed by clustering, each of which has its members. This cluster is formed enough to represent the real conditions, cluster which has a high LST value or has an NBR value. A high LST value indicates an increase in the area's temperature; a high NBR value indicates a fire has occurred in the area. The combination of LST and NBR values indicates the area has experienced forest and land fires. This study shows that DBSCAN clustered fire and surface temperature data following data from the Central Statistics Agency of Riau Province. Proven DBSCAN can cluster satellite imagery data in Riau province into several clusters that have a high incidence of land fires.

Authentication is a method for securing an account by verifying the user identity by inputting email with a password. Two factor authentications is an authentication system that combines the first-factor authentication with the second factor. General two factor authentication by entering an email or username with a password are similar. However, two factor authentication requires additional information that must be inputted by the user. Additional information can be in the form of tokens or one-time passwords (OTP). Two factor authentications generally still uses third-party services to generate token or OTP still have vulnerable because can attacked from tokens steal through MITM and found that the generated tokens with the same value. Therefore, we propose a two-factor authentication framework based on ethereum blockchain with dApp as token generation system. Firstly, outcome from the analysis of the system, next succeeded in creating a two-factor authentication system without using third-parties. Second, token system generate up to 3164 different tokens in one second and has been collisions tested. Third, security method to protect token from MITM attack. The attacker unable to get access caused all the checking are done by dApp user authentication.

Gross motor development in children influences the development of self-confidence and the concept of self-formation as they mature. Many people assume that gross motor development is often ruled out compared to other aspects of child development because the perception of gross motor development will automatically increase with age, when in fact the gross motor development must continue to be stimulated so that it develops perfectly. The activity used in this research is the game of putting balls into a hole by moving the game box (Drop Box). This research aims to build a device that has been designed and assess the ability/performance of the system based on the parameters of functionality, the accuracy of values , and reading speed. In this research, the Drop Box game implements Internet of Things (IoT) to support recording activities and processing data obtained from recording children's activities. In this research also proposed a suitable IoT architecture and has been applied in the development of the Drop Box game device. We carry out functional system testing and system performance testing based on accuracy parameters and speed-reading parameters. The test results show that the functionality of the system runs with an average of 100%. For system performance, the result is 86.59% for 20 ms as the optimal delay in testing accuracy and 79 ms for reading speed.

Ethereum is one of the oldest examples of blockchain technology provides a system that converts centralized storage to distributed and records transactions by way of decentralized and not by a centralized system and can be verified by each node, therefore it is suitable for storing fingerprints from official diploma documents and transcripts that are published. Smart contract is needed for making contract transactions to Ethereum with programming code, so contracts such as diplomas and transcripts uploaded on the Ethereum blockchain can distribute and produce diploma validation and the authenticity of transcripts with transaction hash, consensus, and comply with ERC-721 token standardization. The results showed that a sample of 5 electronic documents in pdf format with a transaction speed of 1 second on each file that were published and secured with Ethereum blockchain technology can be easily verified for authenticity, the system proposed and developed by us takes in consideration invalid and failure cases by giving the necessary feedback to the user.

Readiness Improvement Strategy
The development of information technology has reached into various fields, such as education. The emergence of e-learning is one manifestation of information and communication technology (ICT) in education. Until recently, only a few universities (6%) have implemented e-learning in Indonesia. Those that have implemented e-learning are still not optimally utilized. Some experts have also warned all organizations that will adopt e-learning to be concerned with thorough preparation to avoid overruns in costs. There is a method that consists of factors to measure the level of readiness of tertiary institutions towards the implementation of e-learning. The level of readiness is obtained through the distribution of questionnaires using 5 Likert scales. This research proposed a framework that produces four factors from the university, which covers the lecturer’s characteristics, e-learning facilities, learning environment, learning management, and four factors from the student’s side, namely, self-learning, motivation, learner’s control, student’s characteristic. The measurement results show the level of readiness for e-learning implementation in tertiary institutions in Central Java Province reaches level 3 or ready but needs a few improvements. Improvements that must be made includes (1) Designing exciting learning content through interactive multimedia; (2) Increasing the frequency of e-workshops or e-training related to technological developments, especially to e-learning; (3) encouraging students to be more active in discussions and giving opinions; (4) Developing plans related to infrastructure such as servers related to their capacities; (5) strengthening the role of IT units in serving e-learning users.

image segmentation
Image segmentation is a predefined process of image processing to determine a specific object. One of the problems in food recognition and food estimation is the lack of quality of the result of image segmentation. This paper presents a comparative study of different color space and color channel selection in image segmentation of food images. Based on previous research regarding image segmentation used in food leftover estimation, this paper proposed a different approach to selecting color space and color channel based on the score of Intersection Over Union (IOU) and Dice from the whole dataset. The color transformation is required, and five color spaces were used: CIELAB, HSV, YUV, YCbCr, and HLS. The result shows that A in LAB and H in HLS are better to produce segmentation than other color channels, with the Dice score of both is 5 (the highest score). It concludes that this color channel selection is applicable to be embedded in the Automatic Food Leftover Estimation (AFLE) algorithm.

The Quran search system is a search system that was built to make it easier for Indonesians to find a verse with text by Indonesian pronunciation, this is a solution for users who have difficulty writing or typing Arabic characters. Quran search system with phonetic similarity can make it easier for Indonesian Muslims to find a particular verse. Lafzi was one of the systems that developed the search, then Lafzi was further developed under the name Lafzi+. The Lafzi+ system can handle searches with typo queries but there are still fewer variations regarding typing error types. In this research Lafzi++, an improvement from previous development to handle typographical error types was carried out by applying typo correction using the autocomplete method to correct incorrect queries and Damerau Levenshtein distance to calculate the edit distance, so that the system can provide query suggestions when a user mistypes a search, either in the form of substitution, insertion, deletion, or transposition. Users can also search easily because they use Latin characters according to pronunciation in Indonesian. Based on the evaluation results it is known that the system can be better developed, this can be seen from the accuracy value in each query that is tested can surpass the accuracy of the previous system, by getting the highest recall of 96.20% and the highest Mean Average Precision (MAP) reaching 90.69%. The Lafzi++ system can improve the previous system.

Multi-Criteria Decision Making
organic rice
Land conversion to organic agriculture is the answer to land degradation problems that interfere with land resources sustainability. An evaluation of land-use suitability is crucial to measure the appropriateness of land for agricultural cultivation. Specifically, organic rice cultivation has some particular standard criteria such as temperature, rainfall, soil depth, pH, c-organic, slope, erosion level, a transition period that influence ranking results, and land suitability classes. Eight organic farmlands were used as alternatives, namely Sawangan, Mangunsari, Tirtosari, Podosoko, Butuh, Krogowanan, Kapuhan, and Jati. Fuzzy Analytic Hierarchy process is used to determine the level of importance of the criteria based on weight assessments by three agricultural experts. The ELECTRE method is applied to rank the most suitable land from several alternatives for organic rice cultivation. The combination of these two multi-criteria decision-making methods complements each other to solve problems in land suitability evaluation. A web-based decision support system (DSS) was created to accelerate data processing integration and present factual information from the land suitability selection process. The implementation of DSS with fuzzy-AHP ELECTRE for evaluating land-use suitability in organic rice cultivation provided the best score for Tirtosari with Ekl=4 and spearman rank correlation the system comparison results with actual data rs=0.95. This study's results indicate that integrating the web with fuzzy-AHP ELECTRE is quite effectively applied for decision-making in organic farming.

neo4j graph database
A movie recommendation is a long-standing challenge. Figuring out the viewer’s interest in movies is still a problem since a huge number of movies are released in no time. In the meantime, people cannot enjoy all available new releases or unseen movies due to their limited time. They also still need to choose which movies to watch when they have spare time. This situation is not good for the movie business too. In order to satisfy people in choosing what movies to watch and to boost movie sales, a system that can recommend suitable movies is required, either unseen in the past or new releases. This paper focuses on the hybrid approach, a combination of content-based and collaborative filtering, using a graph-based model. This hybrid approach is proposed to overcome the drawbacks of combination in the content-based and collaborative filtering. The graph database, Neo4j is used to store the collaborative features, such as movies with its genres, and ratings. Since the movie’s closed caption is rarely considered to be used in a recommendation, the proposed method evaluates the impact of using this syntactic feature. From the early test, the combination of collaborative filtering and content-based using closed caption gives a slightly better result than without closed caption, especially in finding similar movies such as sequel or prequel.

vaccines
Vaccines are biological products that have an important role in human immunity. In Indonesia, some vaccines are categorized as compulsory vaccines and additional vaccines. The demand for additional vaccines is less predictable because they are not mandatory for use. This of course makes the amount of demand for vaccines less predictable. Also, the price of additional vaccines is not cheap when compared to the price of mandatory vaccines. So that the management of vaccines in the pharmacy warehouse is needed so that the amount of supply and demand is balanced so that the costs incurred will be more optimal. The information system regarding vaccine reordering is carried out using a reorder point so that the pharmacy warehouse can order according to the right need and at the right time. The data used are demand data, prices, storage costs, and message costs. The results of calculations using reorder points within four months with a total purchase for the Rotavirus vaccine was 62 for IDR 28,274,948 and 70 for the hospital of IDR 31,801,500 with a difference of IDR 3,528,552. The calculation result using the reorder point for the Hexaxim vaccine with a total purchase for 4 months was 61 with a nominal value of IDR 58,380,060 while the calculation in the hospital was 67 with a nominal value of IDR 63,971,000 so that a nominal difference of IDR 5,590,940 was obtained. Use of the return point can be used to alarm when and how many vaccines to order. This can be seen from the cost difference between the pharmacy warehouse and the calculation using the reorder point for the Hexaxim vaccine and the Rotavirus vaccine.

TOPSIS
Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is an algorithm that can be used for alternative design in a decision support system (DSS). TOPSIS provides recommendation so that users can get information that support their decision, for example a tourist wants to visit a tourist destination in Malang, then TOPSIS provides recommendations of tourist destinations in the form of ranking recommendation, with the highest rank is the most recommended recommendation. TOPSIS-based Mobile Decision Support System (DSS) has relatively low algorithm complexity. However, there are some cases that require development from personal DSS to group DSS, for example tourists rarely come alone, in which case most of them invite friends or family. For users who are more than 1 person, the TOPSIS algorithm can be combined with the BORDA algorithm. This study explains about the implementation & testing of TOPSIS and TOPSIS-BORDA as algorithms for personal and group DSS in mobile-based tourism recommendation system in Malang. Correlation testing was conducted to test the effectiveness of TOPSIS in mobile-based recommendation system. In previous study, correlation testing for personal DSS showed that there was a relationship between the recommendation and user choice, with correlation value of 0.770769231. In this study, correlation testing for group DSS showed there is a positive correlation of 0.88 between the recommendations of the group produced by TOPSIS-BORDA and personal recommendations for each user produced by TOPSIS.

virtual community
A virtual community is one form of Community of Practices that resides on the internet. This community consists of people who share problems or interests in specific topics. A lot of knowledge comes from this kind of community where the members shared their knowledge voluntarily. Knowledge itself is a valuable resource that gives the owner have an advantage. This research tried to observe what are the driver of this behavior. Knowing these variables could help the organization in defining knowledge sharing system functionality. The variables collected using PRISMA Systematic Literature Review (SLR) protocols, and the hypotheses tested using Partial Least Squares Structural Equation Modeling (PLS-SEM). From this research, we observed that self-efficacy and supporting others significantly influence someone to share their knowledge.

Payload authentication is vulnerable to Man-in-the-middle (MITM) attack. Blockchain technology offers methods such as peer to peer, block hash, and proof-of-work to secure the payload of authentication process. The implementation uses block hash and proof-of-work methods on blockchain technology and testing is using White-box-testing and security tests distributed to system security practitioners who are competent in MITM attacks. The analyisis results before implementing Blockchain technology show that the authentication payload is still in plain text, so the data confidentiality has not minimize passive voice. After implementing Blockchain technology to the system, white-box testing using the Wireshark gives the result that the authentication payload sent has been well encrypted and safe enough. The percentage of security test results gets 95% which shows that securing the system from MITM attacks is relatively high. Although it has succeeded in securing the system from MITM attacks, it still has a vulnerability from other cyber attacks, so implementation of the Blockchain needs security improvisation.

classification
imbalanced dataset
oversampling
performance analysis
Class imbalance occurs when the distribution of classes between the majority and the minority classes is not the same. The data on imbalanced classes may vary from mild to severe. The effect of high-class imbalance may affect the overall classification accuracy since the model is most likely to predict most of the data that fall within the majority class. Such a model will give biased results, and the performance predictions for the minority class often have no impact on the model. The use of the oversampling technique is one way to deal with high-class imbalance, but only a few are used to solve data imbalance. This study aims for an in-depth performance analysis of the oversampling techniques to address the high-class imbalance problem. The addition of the oversampling technique will balance each class’s data to provide unbiased evaluation results in modeling. We compared the performance of Random Oversampling (ROS), ADASYN, SMOTE, and Borderline-SMOTE techniques. All oversampling techniques will be combined with machine learning methods such as Random Forest, Logistic Regression, and k-Nearest Neighbor (KNN). The test results show that Random Forest with Borderline-SMOTE gives the best value with an accuracy value of 0.9997, 0.9474 precision, 0.8571 recall, 0.9000 F1-score, 0.9388 ROC-AUC, and 0.8581 PRAUC of the overall oversampling technique.

The COVID-19 pandemic has various impacts on changing people’s behavior socially and individually. This study identifies the Degree-of-Concern topic of COVID-19 through citizen conversations on Twitter. It aims to help related parties make policies for developing appropriate emergency response strategies in dealing with changes in people’s behavior due to the pandemic. The object of research is 12,000 data from verified Twitter accounts in Surabaya. The varied nature of Twitter needs to be classified to address specific COVID-19 topics. The first stage of classification is to separate Twitter data into COVID-19 and non-COVID-19. The second stage is to classify the COVID-19 data into seven classes: warnings and suggestions, notification of information, donations, emotional support, seeking help, criticism, and hoaxes. Classification is carried out using a combination of word embedding (Word2Vec and fastText) and deep learning methods (CNN, RNN, and LSTM). The trial was carried out with three scenarios with different numbers of train data for each scenario. The classification results show the highest accuracy is 97.3% and 99.4% for the first and second stage classification obtained from the combination of fastText and LSTM. The results show that the classification of the COVID-19 topic can be used to identify Degree-of-Concern properly. The results of the Degree-of-Concern identification based on the classification can be used as a basis for related parties in making policies to formulate appropriate emergency response strategies in dealing with changes in public behavior due to a pandemic.

software similarity
similarity measurement
UML diagram similarity
semantic similarity
structural similarity
Every piece of software uses a model to derive its operational, auxiliary, and functional procedures. Unified Modeling Language (UML) is a standard displaying language for determining, recording, and building a software product. Several algorithms have been used by researchers to measure similarities between UML artifacts. However, there no literature studies have considered measurements of UML diagram similarities. This paper presents the results of a systematic literature review concerning similarity measurements between the UML diagrams of different software products. The study reviews and identifies similarity measurements of UML artifacts, with class diagram, sequence diagram, statechart diagram, and use case diagram being UML diagrams that are widely used as research objects for measuring similarity. Measuring similarity enables resolution of the problem domains of software reuse, similarity measurement, and clone detection. The instruments used to measure similarity are semantic and structural similarity. The findings indicate opportunities for future research regarding calculating other UML diagrams, compiling calculation information for each diagram, adapting semantic and structural similarity calculation methods, determining the best weight for each item in the diagram, testing novel proposed methods, and building or finding good datasets for use as testing material.

Jabareen
The increase in the number of internet users in Indonesia as much as 175.4 million as recorded in the Datareportal.com report and 4.83 billion globally, impact the increase in the number of cyber fraud cases. Data states that 96% of fraud cases are not resolved due to fraud methods carried out online and make it difficult for legal officers to obtain evidence. Previous fraud investigation research mainly focused on fraud detection, so this research focuses on submitting a framework for investigating cyber fraud cases. The cyber fraud case requires a new framework for investigation because in this fraud case, there is digital evidence that is very prone to be damaged, lost, or modified, which makes this case unsolved. This research aims to develop a framework that is expected to help auditors to uncover cases of cyber fraud so that resolved cyber fraud cases can increase. The method used in making this framework uses Jabareen's conceptual framework development method, which consists of 6 stages, namely, Mapping the selected data source, extensive reading and categorizing of the chosen data, Identifying and naming objects, Deconstructing and categorizing the concept, Integrating concept, Synthesis, resynthesis. And make it all sense. The framework for cyber fraud investigation uses 22 digital forensic frameworks and eight frameworks for fraud audit investigations. The results of developing a framework using the Jabareen method resulted in 8 stages, integrating various concepts selected from digital forensics and fraud audits. Evaluation of framework development was carried out by giving limited questionnaires to practitioners and academics, which produced 89% for the feasibility value and needs of the framework and 67% there is no need for changes to the framework being developed.

This study used 104 respondents of Shopee Consumer and analyzed with the WebQual with Importance Performance Analysis (IPA) method and Structural Equation Model (SEM). The result is that the service quality variable significantly influence e-commerce website customer satisfaction variable, customer satisfaction variable has no significant effect on e-commerce website customer loyalty variables, and website service quality variable significantly influence e-commerce website customer loyalty variable. The attributes of WebQual 4.0 that need to be considered by e-commerce management to impact the level of user satisfaction and customer loyalty are “design by the type of website”, “provide simple-to-understand information”, “provide information following the format”, “feel safe to complete transactions”, “the website makes the positive/absolute experience for me”, and “provide detailed information”.
