This research aims to develop an early flood warning system using the Telegram application as an early sender of information, if the water level has reached a predetermined limit. Test results: In terms of Functionality and Usability, the results of the functionality feasibility percentage were 100% and as many as 20 respondents or 100% assessed that the tool developed based on the Usability context was at 100% in the very good category. The detection speed test results show that the detection speed on the device is around 2-3 s and the speed of sending information on Oled is around 2-3 s and the speed of sending information to Telegram is 2-3 s.</p> 2024-04-30T00:00:00+08:00 Copyright (c) 2024 Journal of Electrical Engineering and Informatics https://journal.unm.ac.id/index.php/JEENI/article/view/1687 ANALYSIS OF NETWORKS IN ELECTRICAL DISTRIBUTION SYSTEMS USING FAULT TREE ANALYSIS METHOD IN PLN (PERSERO) UP3 BULUKUMBA ULP PANRITA LOPI 2024-03-18T12:11:57+08:00 Riswandi Riswandi andhypsb04@gmail.com Alimuddin Sa'ban Miru alimuddin.miru@unm.ac.id Firdaus Firdaus dauselektro@unm.ac.id <p style="text-align: justify;">Distribution of electricity is often interrupted which can result in the process of distribution of power to the consumer becoming abnormal. Therefore, an analysis of the cause of disturbance of the electricity distribution network needs to be carried out. This research is conducted using the method of Fault Tree Analysis (FTA) because it is an effective method in determining the cause of the disturbance and with the help of Microsoft Exel as well as manual calculations. The results of the research obtained that which is the main factor that causes the occurrence of the disruption in the system of distribution of electric energy in PT PLN (Persero) UP3 Bulukumba ULP Panrita Lopi is due to disruptions in the distribution equipment, animal activity, human activity, material interference, error of installation and nature interferences. From the results of the study, it can be concluded that there are six factors that cause the disturbance of the process of electricity distribution to consumption, then become a priority for PLN based on the percentage of disruption occurred.</p> 2024-04-30T00:00:00+08:00 Copyright (c) 2024 Journal of Electrical Engineering and Informatics https://journal.unm.ac.id/index.php/JEENI/article/view/1507 CONSUMER INFORMATION SYSTEM IN WEB-BASED COOPERATIVES: CASE STUDY OF DIRA JAYA SINAR RESKI COOPERATIVE 2024-03-22T19:42:00+08:00 Fathin Kartika Fathin fathinkartika06@gmail.com Saharuddin Saharuddin saharuddin@unm.ac.id Fathahillah Fathahillah fathahillah@unm.ac.id <p style="text-align: justify;">This study aims to determine the results of the development of consumer information systems at the Dira Jaya Sinar Reski cooperative as well as find out user responses to the system to be developed. This research uses the type of R&amp;D (Research and development) research and prototype development model that uses data collection techniques such as interviews, observations, and questionnaires. Based on the results of the research, a Web-Based Consumer Information System was developed at the Dira Jaya Sinar Reski Cooperative which has been tested using ISO 25010 testing using 8 aspects of testing that have been validated by content experts. The final result of the overall assessment is that the Consumer Information System at the Web-Based Dira Jaya Sinar Reski Cooperative was declared valid by the validator lecturers, and declared effective based on functional suitability aspects, and declared practical based on user responses that have been tested from the usability aspect.</p> 2024-04-30T00:00:00+08:00 Copyright (c) 2024 Journal of Electrical Engineering and Informatics https://journal.unm.ac.id/index.php/JEENI/article/view/1826 DESIGN AND DEVELOPMENT OF AN ANDROID-BASED FERTILIZER ORDERING APPLICATION IN THE BANGKALA REGION 2024-04-16T13:53:38+08:00 Lutvi Karimah Lutvi lutvikarimah14@gmail.com Fathahillah Fathahillah fathahillah@unm.ac.id Udin Sidik Sidin udin.sidik.sidin@unm.ac.id <p style="text-align: justify;">In the Bangkala Region of Jeneponto Regency, farmers continue to depend on the conventional system for the fertilizer ordering process. This system results in inefficiencies and consumes the time of both sellers and buyers. We require an Android-based fertilizer ordering system that integrates directly with the server. The objective of this study is to develop an Android-based application for ordering fertilizer in the Bangkala region. This application was developed using the Research and Development (R&amp;D) methodology and the <em>waterfall</em> development model. The results of this research have yielded a product in the form of an Android-based fertilizer ordering application, which will be utilized by farmers in the Bangkala Region, Jeneponto Regency. The system was tested using the ISO 25010 standard across four aspects: functional suitability, portability, usability, and performance efficiency. Functional suitability testing indicates that this application is "suitable" for use. Portability testing revealed that this fertilizer ordering application system runs well on several versions of Android. The usability testing results of the application have been categorized as "Very Good". Furthermore, performance efficiency testing shows that the CPU usage is at 4%, memory usage at 156.4 Mb, and the application network activity is at 80 Kb/s. Based on this data, the application has been well-received by users and can serve as a streamlined platform for ordering fertilizers for farmers.</p> 2024-04-30T00:00:00+08:00 Copyright (c) 2024 Journal of Electrical Engineering and Informatics https://journal.unm.ac.id/index.php/JEENI/article/view/1682 DEVELOPMENT OF ACADEMIC ADVISING INFORMATION SYSTEM APPLICATIONS AT MAKASSAR STATE UNIVERSITY USING THE ANDROID PLATFORM 2024-03-18T12:12:33+08:00 Muhammad Rais B muhammadraisb2@gmail.com Muhammad Agung agung@unm.ac.id Alimuddin Sa’ban Miru alimuddin.miru@unm.ac.id <p style="text-align: justify;">Advising is the process where students communicate about issues that may arise during their study period. However, it is often hindered by the busy schedules and different timetables between students and their academic advisors. Therefore, a system has been developed to facilitate the advising process using the Android platform. This research adopts the Research and Development (R&amp;D) methodology, specifically using the waterfall development model. Data collection techniques include interviews and questionnaires. The application is tested based on the ISO/IEC 25010 quality standards, covering four aspects: functional suitability, performance efficiency, usability, and portability. The functional suitability testing involved two expert professors, and 24 features were tested, indicating that the application is "Suitable" for use. Portability testing on the application was conducted by observing the output on three Android versions: Nougat, Red Velvet Cake, and Tiramisu. The results showed that the application can run on all three Android versions. Performance efficiency testing utilized the Android Profiler tool to assess CPU, memory, and network usage while running the application. The findings revealed that CPU usage was less than 50%, memory allocation was 122.2 MB, and network usage was less than 48 KB/s. Usability testing conducted by students resulted in a test score of 81.6%, categorized as "Very Good" feasibility.</p> 2024-04-30T00:00:00+08:00 Copyright (c) 2024 Journal of Electrical Engineering and Informatics
