Abstract

Analysis of course completion at Universitas Advent Indonesia (UNAI) is an important thing to do. By knowing the course completion of students early, UNAI can take necessary actions to improve students' course completion. This study reveals the influence of lecturer evaluation scores on student course completion in the Web Programming 1, Web Programming 2, and Programming Algorithm 1 courses during the academic years 2020-2021 to 2022-2023. The purpose of this study is to see the influence of lecturer evaluation scores on student course completion in these courses and which competencies most affect student scores. The method used in this study is data mining with the C4.5 decision tree algorithm. The results of this study show that out of 5 competencies tested, 3 competencies affect student course completion. This study uses a confusion matrix evaluation model that produces a prediction accuracy of 80%.

Abstract

The Internet of Things (IoT) system has been implemented at PT XXX to improve operational efficiency, especially in monitoring the Ingersoll C1000 centrifugal compressor. This compressor produces high-pressure air that plays an important role in the nickel processing process. This system integrates the Message Queuing Telemetry Transport (MQTT) protocol, IoT sensors, Teltonika RUT951 gateway, and Mosquitto broker to send temperature data in JSON format in real-time. This data is then visualized using AVEVA PI Vision, which provides trend-based information to support analysis and decision making. Previously, monitoring was only carried out locally without historical data, making it difficult to detect potential damage. Operators also had to conduct direct inspections to the field to check the condition of the compressor, which was time-consuming and inefficient. With this IoT-based system, data can be monitored directly from the head office, saving travel time and increasing operational productivity. Trials in a real operational environment showed that data transmission via MQTT was stable even in a limited network. Visualization in AVEVA PI Vision provides a real-time picture that supports early detection of anomalies and data-driven decision making. The results of this study indicate that IoT technology with the MQTT protocol is able to improve monitoring efficiency, optimize system performance, and provide innovative solutions to connectivity challenges in the industry. This implementation also opens up new opportunities for IoT applications in supporting operational efficiency and sustainability.

Abstract

This research applies a hierarchical clustering algorithm to identify population density patterns in West Java (18 regencies, 9 cities) as a basis for natural disaster management. Population density data for 2020-2022 from the West Java Population Office was analyzed to group areas into three categories: densest, medium, and lowest. The hierarchical clustering method was used to group areas based on population density and flood potential, with the additional attribute of river presence. The clustering results were evaluated using the Davies-Bouldin index. The results showed that the algorithm was successfully applied, grouping 20 districts/cities with the lowest population density (Cluster 0), 3 districts/cities with medium density (Cluster 1), and 4 districts/cities with the densest density (Cluster 2).This research is expected to provide insight to the government and related institutions in planning disaster mitigation based on population density patterns, so as to reduce the risk of natural disasters in the future. This research takes data from the official source https://jabar.bps.go.id/indicator/12/245/1/kepadatan-penduduk-menurut-kabupaten-kota.html. The main objective of this research is to understand population density patterns that can provide an indication of the level of risk to certain natural disasters in the West Java region. This information is expected to be used as a basis for more effective and efficient disaster management strategies in the future. The implication of this research shows that by understanding the pattern of population density and river distribution through the hierarchical clustering method, the government and related institutions can formulate more targeted disaster management strategies.

Abstract

This community service program aimed to enhance digital literacy and student creativity among junior high school students through training in the development of educational games using the Scratch platform. The training was conducted in two sessions at Perguruan Advent Parongpong School and involved 8th and 9th grade students. The first session introduced basic visual programming concepts through a simple project titled Underwater Life, while the second session guided students to create a game called Bat vs Dragonfly, featuring a point system and win-lose logic. The method used was active and participatory, including material presentations, demonstrations, and hands-on practice with assistance. Questionnaire results revealed that most students regularly play games, showed strong interest in learning to create games, and viewed the use of games in learning positively. In the first session, 8 out of 29 students successfully completed the project, while in the second session, 21 out of 30 students completed the game within the allotted time. This activity demonstrated that educational games can effectively foster student interest in learning, logical thinking, and creativity. The outcomes are expected to serve as a foundation for schools to develop extracurricular programs focused on creative technology, and to encourage parents and educators to guide the use of technology in a positive and productive direction.
