In this paper, a recommendation system was proposed using Depth First Search and Simple Multi Attribute Ranking Technique methods. Depth First Search method was used to find all possible alternative schedules. All the possible alternative schedules were used to determine the schedule that best suits student preferences using Simple Multi Attribute Ranking Technique method. The system performance was measured through simulation to get course schedule recommendations for 28 students. The simulation results were compared with the ideal schedule desired by the students and the real course schedule for those students. The accuracy of the recommended schedule against the ideal schedule desired by students was 70.8% with an average processing time of 1.05 seconds. The accuracy of the recommended schedule increased to about 91% when compared to the actual student courses schedule.

Currently, the quality of handling cybercrime in Indonesia is still minimal, starting with the problem of collecting evidence that tends to be incomplete, errors during the process of acquiring evidence to the most severe loss and damage to the evidence. Static Forensics is one type of digital forensics method that obtains digital evidence by extracting and analyzing it after an incident occurs, or after the computer system is turned off (post-incident). The NIST Framework is a reference for the digital evidence retrieval and processing process, which was developed by the National Institute of Standards and Technology. The results obtained from the analysis of digital evidence recovery using static forensics methods combined with the NIST framework can be applied properly and optimally. The test was carried out 20 times, with the results of the digital evidence recovery accuracy reaching 100% on the three devices.

In this research, modeling of a gender identification system based on voice in real-time has been carried out on a Raspberry Pi device. This system is implemented by 2 methods, namely the YIN algorithm and feature extraction of Mel-Frequency Cepstral Coefficient (MFCC). The test results showed that the success of identification in the tuning parameters of scheme two is better than the first scheme by narrowing the overlapping frequency parameters.

Dari hasil tersebut dapat diketahui bahwa metode <em>Savitzky Golay Filter</em> cocok digunakan untuk tahap pra proses karena mampu meningkatkan nilai koefisien korelasi secara signifikan.</p> 2022-06-26T00:00:00+00:00 Copyright (c) 2022 Jurnal Komputer Terapan  https://jurnal.pcr.ac.id/index.php/jkt/article/view/5209 Algorithm K-Means Clustering Algorithm to Classify the Level of Legal Information Service Objectives in West Java Province 2021-12-13T00:16:49+00:00 Beny Ruhiman benyruhiman@gmail.com Ade Ramdan ader004@brin.go.id Christina Juliane christina.juliane@likmi.ac.id <p><em>Legal Documentation and Information Network (JDIH) is one of the government agencies in the field of law, which is regulated by Presidential Regulation Number 33 of 2012. JDIH consists of central and regional levels, at the provincial level the Bureau of Law and Human Rights is the center of JDIH in its territory. JDIH at the provincial level has the duties and functions to provide guidance and evaluation at the members. To measure the level of community satisfaction with JDIH members in West Java, a survey was conducted using the 360 &nbsp;review ​​method on the website https://jdih.jabarprov.go.id/review.php/. The results contained 18,045 raw data. After preprocessing, 46 datasets and 11 attributes were generated. Cluster modeling uses the K-Means algorithm, the results are evaluated by the Davies Boulding Index (DBI) method. Evaluation results show a low level of similarity so that the distance between clusters is getting higher. On this study is classified into 4 clusters, the lowest satisfaction indicator is known to be in cluster 3 which consists of 10 regions. &nbsp;In this research can be used &nbsp;to determining policies for&nbsp; the government&nbsp; of West Java Province.</em></p> 2022-06-26T00:00:00+00:00 Copyright (c) 2022 Jurnal Komputer Terapan  https://jurnal.pcr.ac.id/index.php/jkt/article/view/4901 Deteksi Tangan Otomatis Pada Video Percakapan Bahasa Isyarat Indonesia Menggunakan Metode Deep Gated Recurrent Unit (GRU) 2021-11-27T06:11:08+00:00 Puji Kurnia Sari pujikurniasari29@gmail.com Gulpi Qorik Oktagalu Pratamasunu pratamasunu@unuja.ac.id Fathorazi Nur Fajri r4si.bint4ng@gmail.com <p>Tunarungu adalah hilangnya pendengaran baik salah satu telinga maupun keduanya. Untuk melakukan komunikasi tunarungu menggunakan bahasa isyarat menggunakan kedua tangannya. Saat ini terdapat 2 sistem bahasa isyarat yaitu BISINDO dan SIBI. Bahasa isyarat adalah bahasa yang menggunakan gerakan tubuh berupa tangan dan bibir untuk menjelaskan sebuah arti. Namun masih banyak masyarakat yang belum paham dengan bahasa isyarat, oleh karena itu dilakukan sebuah penelitian dengan menggunakan metode <em>deep gated recurrent unit</em> (GRU) yang dapat membaca gerakan tangan pada video bahasa isyarat indonesia. Penelitian ini menggunakan 3 class yaitu ucapan hallo, terimakasih, dan sama sama. Tahapan yang dilakukan pada penelitian ini terdiri dari pengolahan video atau proses pre-processing pada video. Pengujian terhadap 45 video data training dan 36 video data testing. Pengujian yang dilakukan terhadap data testing menghasilkan nilai akurasi sebesar 88%.</p> 2022-06-26T00:00:00+00:00 Copyright (c) 2022 Jurnal Komputer Terapan  https://jurnal.pcr.ac.id/index.php/jkt/article/view/5351 Implementasi Ekstraksi Fitur untuk Pengelompokan Dokumen Proposal Menggunakan Algoritma Naïve Bayes 2022-06-20T02:54:34+00:00 Dini Nurmalasari dini@pcr.ac.id Heri Ribut Yuliantoro heriry@pcr.ac.id <p><em>Text mining is the process of discovering new, previously unknown information from several text documents. Text mining can be applied to the fields of information extraction, topic tracking, document summarization, document categorization or grouping, concept linking or question answering systems. One thing that is often done in implementing text mining is information extraction. Information extraction aims to extract information from unstructured documents into structured data, with the aim of making it easier to analyze the data. In this study, feature extraction will be used to extract features from the Community Service document, using the Frequent Itemset Mining (FIM) algorithm. The features taken are PKM Title, Abstract, Year of Service, Location, and research topic. After obtaining the features, the service topics will be grouped using the Naive Bayes algorithm. The results of this study were tested using a confusion matrix, with an accuracy of 70%. Factors that affect the accuracy results include the amount of training data, the distribution of training data, and the optimization of the algorithm used</em></p> 2022-06-26T00:00:00+00:00 Copyright (c) 2022 Jurnal Komputer Terapan
