Abstract

This study aims to design, implement, and evaluate a real-time electrical energy consumption monitoring system in the Haji Rani Building using the Arduino Uno microcontroller and the Blynk platform. The system integrates the PZEM-004T sensor for measuring voltage, current, power, and electrical energy, while the Wemos D1 Mini facilitates wireless data transmission via a Wi-Fi network. The research follows a Research and Development (R&D) methodology with a prototype development model. Data collection techniques include observation, documentation, and direct testing. The test results indicate that the developed system has a good level of accuracy, with an average deviation of 4.21% compared to standard measuring instruments. Despite minor deviations, the system successfully provides real-time monitoring with a fast response through the Blynk application, enabling remote access. Functionality evaluation using the Guttman scale, conducted by two content experts, confirms that the system meets the expected standards in terms of reliability, accuracy, and usability. However, the system's reliance on a stable Wi-Fi connection may affect monitoring reliability in areas with poor network coverage. Additionally, the accuracy of the PZEM-004T sensor, while acceptable for general monitoring, could be improved with more precise sensors. Future research should focus on integrating more accurate sensors, implementing machine learning algorithms for energy consumption analysis, and developing an automated IoT-based energy management system. By addressing these aspects, the proposed system can be further enhanced to improve energy efficiency and sustainability.

Abstract

In the islands, the use of electrical energy is not only for household purposes, but also to support the education, health, small industry and transport sectors. This increase in electrical energy demand is increasingly urgent, given the importance of electricity in driving technology, improving people's quality of life, and supporting the sustainability of life, thus requiring special attention to maintain the availability of electrical energy. Grid management involves proper planning of load requirements. Therefore, accurate load forecasting will ensure the safe, reliable, and economical operation of power systems. In recent years, researchers have proposed many models for electricity forecasting. In this study, the backpropagation ANN method is used to forecast electrical energy demand until 2035 on Karanrang island which will be compared with the prediction results using the linear regression method. Based on the results of research and discussion of the prediction results, it can be concluded that the MAPE value of the backpropagation ANN is 8% and from the linear regression method is 10.4% so it can be concluded that prediction with the backpropagation ANN method is more optimal. The MAPE value of 8% is categorised as a very good prediction result.

Abstract

Low energy absorption efficiency in static solar panels remains a key challenge for renewable energy implementation in Indonesia. This study aims to develop and evaluate an automatic solar panel drive system based on Arduino Uno, integrating an RTC module and INA219 sensor to optimize panel orientation according to real-time sun position. The methodology involved designing a prototype system consisting of a 10 Wp solar panel, SG90 servo motor, RTC DS3231 module, and INA219 sensor, tested outdoors under light intensity ranging from 800 to 1000 lux. Experimental results showed that the automatic system increased average voltage output to 13.9 V and enhanced energy capture by 6-12% compared to static panels under clear sky conditions. Usability assessments using the System Usability Scale indicated that the system was rated as highly effective and practical at the prototype stage. The novelty of this research lies in the integration of RTC-based time scheduling with servo motor control, offering a stable, low-cost alternative to LDR-based systems for photovoltaic optimization in tropical environments. The developed system has potential for broader implementation to improve solar panel efficiency, though further studies are recommended to validate performance over longer durations and diverse weather conditions

Abstract

This study evaluates the satisfaction level of students in the Electrical Engineering Education Department, Faculty of Engineering, Makassar State University (PTE FT UNM) in using the My-SAMS (My Single Academic Management System) application based on the End User Computing Satisfaction (EUCS) model, which measures satisfaction through content, accuracy, format, ease of use, and timeliness. Using a quantitative ex post facto design, data were collected from 136 students (2018–2023 cohorts) through a 20-item Likert-scale questionnaire. The research instruments were tested for validity using the product-moment correlation and for reliability using Cronbach’s Alpha, both showing acceptable results. Data analysis employed descriptive statistics using SPSS 23 and Excel 2021 to identify satisfaction patterns. The findings showed that students were moderately satisfied with content (45%), format (54%), ease of use (57%), and timeliness (46%), while the accuracy dimension was rated dissatisfied (33%). These results suggest that while My-SAMS is user-friendly, issues remain regarding data accuracy and synchronization. It is recommended that system developers enhance data validation and integration processes and provide continuous operator training to ensure data consistency. In conclusion, the study emphasizes that My-SAMS has achieved moderate success in meeting user expectations but requires further improvements in information accuracy and reliability to strengthen trust and system performance. The findings are expected to serve as a reference for improving academic digital services and as a foundation for further research on user satisfaction in academic information systems.
