Abstract

Getting information on routes can be he main problem for visitors. For example in determining the route to a proper place for eating and how to find the closest route to a mall. Based on the existing problems, this study proposes an application for finding information about places that visitors want to go based on the closest route. Algorithm A-Star (A*) was implemented that uses the distance estimation by finding the closest path to the destination using a heuristic function as a basis to select from several alternatives effectively. The result showed that an android application can give the information about the location of places to visit for eating and malls by calculating the distance from the starting point to the end point.

Abstract

Watermarking adalah suatu metode yang digunakan dalam pengamanan hak otentikasi suatu gambar atau video. Oleh karena semakin meningkatnya jumlah pengiriman atau penggandaan suatu karya gambar atau video melalui internet, menyebabkan timbulnya permasalahan baru yaitu bagaimana membuktikan hak kepemilikan dari suatu citra digital (gambar atau video). Pada penelitian ini diterapkan suatu metode yang aman dalam menerapkan watermarking pada video dengan menggunakan Discrete Cosine Transform (DCT) pada domain frekuensi. Video merupakan susunan dari sejumlah frame, dimana setiap frame dianggap sebagai suatu citra tak bergerak (gambar). Penanaman watermark pada video memiliki tantangan tersendiri, dimana watermark di tanamkan ke beberapa atau semua frame yang ada pada video. Adapun konsep 3-Dimensi yang diterapkan memberikan efisiensi dalam menanamkan watermark pada seluruh frame dari suatu video bahkan dengan durasi yang sangat panjang sekalipun. Hasil penelitian ini menunjukkan bahwa metode watermarking video dengan konsep 3-dimensi dapat menjadi salah satu opsi untuk mengamankan hak otentikasi dari suatu video.

Abstract

The Minimum Competency Assessment (AKM) is an assessment of the basic competencies that all students need in order to be able to develop their own capacity and participate positively in society. The aim of AKM is to measure competency at the individual student level, which is expected for all students to reach a proficient or proficient level of competence. The minimum competency assessment since 2021 has been carried out online using the AKM-Kelas application provided by the Pusmenjar Kemdikbud. The challenge that later arises in implementing this is the ability of the school community to operate the application, apart from facilities and infrastructure, some schools do not yet have computer laboratory facilities. Based on this, the Kampus Mengajar (KM) program from the Merdeka Belajar Kampus Merdeka (MBKM) will work together to socialize and assist in using the AKM-Class application. In line with this, the participants in the Kampus Mengajar Batch 4 (KM-4) program at SDN 02 Jatireja designed a mentoring program for using the AKM-Kelas application in collaboration with the community service program (Pengabdian kepada Masyarakat - PkM) from Informatics lecturers at Bhayangkara University Jakarta Raya. Through this mentoring program, teachers and grade 5 elementary school students are the main targets as training participants. The main focus of this training is how to install desktop-based applications for teachers as proctors and install Android-based applications for students as AKM participants. This training program is carried out in stages over three consecutive months. The results of this training show an increase in competence that must be owned by teachers and students in the aspects of: AKM knowledge, literacy, numeracy.

Abstract

Gojek is one of Indonesia's most popular online transportation, founded in 2010. The Gojek application has been downloaded one hundred forty-two million times with more than two million drivers and four hundred thousand partners in food delivery services. Due to the increasing use of the Gojek application and the importance of knowing user views about the services provided by the application. In this research, the sentiment analysis is using Support Vector Machine and the Naïve Bayes method to classify positive sentiment and negative sentiment. The target label focus on positive and negative labels to aims avoid the bias that exists in neutrally labeled reviews on the Gojek Application. The research process includes data collection, pre-processing the data, weighting with Term Frequency-Invers Document Frequency, Support Vector Machine, and Naïve Bayes training by dividing the data into 90% training data and 10% testing data and then evaluating the results using a confusion matrix. The results of testing using the Support Vector Machine algorithm resulted in 90% accuracy, 94% recall, 91% precision, and 94% f1-score, therefore the Naïve Bayes algorithm produces 77% accuracy, 96% recall, 77% precision, and 85% f1-score.

Abstract

As a lecturer, the ability to compile research manuscripts is a crucial skill to possess. However, there are still a significant number of junior and senior professors who frequently struggle with writing research papers. There are also many professors who are able to analyse data, but they struggle when it is time to incorporate it into manuscripts. This community service activity aims to assist lecturers in putting together research paper draughts, particularly for community service partners. In general, this activity can be divided into two distinct phases: preparation and implementation. Beginning preparatory activities include the identification of partners' problems and requirements, the creation of activity schedules, and ongoing dialogue between the service team and partners. This is done to level the perception of the carried out activities. Following the completion of the preparatory phase, the implementation of community service occurs. During the implementation phase, participants received training from two instructors using distinct materials. This community service activity uses workshops and resource sharing as its methodology. Before and after the activity, pre- and post-test questionnaires were distributed in order to assess the participants' understanding and knowledge. Community service activities have a significant effect on participants' comprehension when composing research paper draughts, as demonstrated by the findings. 67% of the participants who took the post-test indicated that they comprehended the preparation of research manuscripts based on the results of the data analysis. 33% of the remaining respondents indicated that they did not understand.

Abstract

Clustering infant nutrition based on weight, height, and age is a data analysis method used to group infant nutritional status based on these characteristics. The research on clustering infant nutrition aims to analyze whether there are still many infants in the area with insufficient or excessive nutrition, and to identify groups of infants requiring special attention regarding their nutritional intake. In the analysis of infant nutrition clustering, data on weight, height, and age of infants are collected and then grouped based on similarities in body height and weight at certain ages. The method used in this research is hierarchical clustering, which can help in grouping the data. Clustering analysis can help understand how infants' feeding patterns vary based on their weight, height, and age. The results of research on clustering infant nutrition based on weight, height, and age can provide valuable insights for nutrition experts, pediatricians, and community health workers in developing appropriate intervention programs to improve infant feeding patterns and meet their nutritional needs. Additionally, the results of clustering infant nutrition can also be used to identify groups of infants requiring special attention regarding their nutritional needs, thus minimizing the risk of malnutrition and unhealthy growth in infants.
