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

This study is a quantitative study that aims to a) describe the coordination of protection systems under abnormal conditions in the distribution network and b) to determine the selectiveity of protection systems in isolating equipment in abnormal conditions of distribution networks. Data setting existing rele protection system obtained in PT. PLN (Persero) UP2D Makassar, the data is then processed, simulated, and analyzed using the ETAP 19.0.1 program. The series analyzed in this study is the distribution network PLN ULP Karebosi Paotere refiner with a channel length of 8,234 km, where sktm channel 0.844 km and SUTM 7,390 km, consisting of 33 distribution substations.  The results showed that the flow of short circuit disruption on Hatta buses was: 3-Phase by 3,887 kA, Line-to-Ground by 3,550 kA, Line-to-Line by 3,357 kA, and Line-to-Line-to-Ground by 3,831 kA.
