Abstract

Plastic injection machine is a plastic product making machine with an injection molding process. Plastic injection machines at PT Shimano Batam currently cannot be monitored automatically. Therefore, a system is needed that monitors and stores all data about the performance of the plastic injection machine automatically. In this system Arduino Uno is used as a microcontroller of the plastic injection machine signal and the Xbee Pro S2C module is used as a sender and receiver of data packets from the plastic injection machine, the data is processed and then displayed on a PC and stored on the server. The test results of this system show that the machine status data matches the data displayed on the PC. From the results of testing the engine cycle time as much as 11 times, there is the largest difference in processing time, which is 1.20 seconds. From the results of reliability testing, packet loss was obtained by 0.006%. Xbee Pro S2C communication testing with a distance of 1 meter to 60 meters was successful without any data packets lost, when testing Xbee Pro S2C communication with a distance of 85 meters to 110 meters there were 30 data packets lost.

Abstract

Rapid technological advancements in electrical engineering education require innovative learning media that bridge the gap between theoretical concepts and practical applications, especially for complex topics such as low-power inverters. This study developed and evaluated an AI-integrated learning media for low-power inverters, utilizing the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The media's effectiveness was assessed through a single-group pretest-posttest design involving 40 undergraduate electrical engineering students. Validation by content and media experts deemed the media highly feasible, with an average feasibility percentage exceeding 85%. The implementation results showed a significant improvement in students' cognitive competencies, with the average test score increasing from 59.75 (pretest) to 83.20 (posttest) and an N-Gain of 0.59, which is categorized as moderate. A paired-sample t-test confirmed a statistically significant difference (p < 0.05) between the pretest and posttest results. Furthermore, students' perceptions were very positive, especially regarding material understanding, learning motivation, interactivity, and self-directed learning. The novelty of these findings demonstrates that integrating artificial intelligence into learning media is not only technically and pedagogically feasible but also effective in improving the learning outcomes of electrical engineering students. The developed media has the potential for broader application in engineering education and supports continued innovation in smart technology-based learning environments.

Abstract

The increasing penetration of photovoltaic (PV) generation in modern distribution networks introduces considerable uncertainty due to the inherently fluctuating nature of solar irradiance. These fluctuations directly affect PV output power, resulting in significant variations in bus voltages, feeder currents, and power losses. Traditional deterministic load flow (DLF) analysis, which assumes fixed PV generation, is unable to capture this stochastic behavior and therefore may lead to inaccurate estimation of system conditions. This study presents a comparative assessment between deterministic load flow using the Backward–Forward Sweep (BFS) method and probabilistic load flow (PLF) based on Hong’s Two-Point Estimate Method (PEM) to evaluate the impact of solar irradiance variability on the performance of PV-integrated distribution networks. Solar irradiance data are statistically characterized to obtain the mean and variance, which are then propagated into PV output power through a linear irradiance–power conversion model. The IEEE 34-bus radial distribution system is used as the test network, with multiple PV units installed at selected buses. The results show that deterministic analysis underestimates voltage deviations and fails to capture the range of power losses induced by PV uncertainty. In particular, the deterministic BFS solution yields a single operating point with real and reactive losses of 0.1582 MW and 0.0479 MVar, whereas the probabilistic 2PEM produces mean losses of 0.105 MW and 0.031 MVar with standard deviations of 0.057 MW and 0.016 MVar, respectively. In contrast to the fixed deterministic voltage curve, probabilistic voltage profiles form a bounded envelope around it, indicating non-negligible downstream voltage variability driven by irradiance fluctuations. Overall, the findings confirm that solar irradiance variability substantially influences distribution system performance, and incorporating probabilistic assessment is essential for more realistic, risk-informed planning and operation of PV-integrated distribution systems.

Abstract

Kegiatan ini bertujuan untuk membantu kelompok Nelayan Bahagia di Kelurahan Belawan 1, Kecamatan Medan Belawan dengan memberikan solusi terhadap permasalahan yang dihadapi, seperti rendahnya hasil tangkapan ikan akibat sarana yang kurang memadai. Solusi yang ditawarkan meliputi penerapan sistem kelistrikan dan alat navigasi fishfinder yang dapat membantu tempat tempat ikan berkumpul. Program ini akan dilaksanakan melalui beberapa tahapan, yaitu sosialisasi, pelatihan, penerapan teknologi, pendampingan, dan evaluasi keberlanjutan program. Metode yang digunakan mencakup pendekatan partisipatif dengan pelibatan langsung mitra dalam setiap tahap kegiatan, serta pendampingan berkelanjutan untuk memastikan keberlanjutan program. Dari hasil uji coba menunjukkan dalam penggunaan fishfinder, waktu operasional nelayan di laut dapat dipangkas hingga 25%, dan nelayan melaporkan peningkatan hasil tangkapan harian sebesar 20–25% dibandingkan sebelum penggunaan alat. Penerapan sistem kelistrikan dan navigasi fishfinder tidak hanya meningkatkan efisiensi energi dan hasil tangkapan, tetapi juga memberikan dampak sosial-ekonomi berkelanjutan bagi nelayan tradisional. Efisiensi bahan bakar menekan biaya operasional, sedangkan peningkatan hasil tangkapan memperbaiki kesejahteraan ekonomi. Pada sisi sosial, teknologi ini meningkatkan keselamatan, pengetahuan, dan solidaritas antar nelayan.
