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

The purpose of this study is to analyze the practicality and effectiveness of android-based sign language recognition learning media applications as an alternative to learning media in extraordinary schools (SLB). This type of research is Research and Development (R&D) with the Concurrent Triangulation design combination method.The subjects of the study were 20 sign language teachers from three SLB schools in the cities of Makassar and Gowa as well as application users who assessed the practicality and effectiveness of the learning media applications that they would teach to deaf students. The data collection technique consists of observation, interviews, literature studies and the distribution of questionnaires/questionnaires. Meanwhile, the instruments used include observation sheets, interview sheets and questionnaire/questionnaire sheets. There are 10 criteria data components to assess the practicality of learning media applications and 15 criteria data components to assess the effectiveness of learning media applications. The results showed that the level of practicality of learning media was 3.65 while the effectiveness level of learning media was 3.41. By using the Likert scale, it can be concluded that android-based sign language recognition learning media applications are very practical and very effective for teachers to use as an alternative to sign language recognition learning media in SLB.

Abstract

Transient overvoltage is a phenomenon in the power system that can be caused by lightning or switching surges. These overvoltages have large amplitudes and short durations, potentially damaging equipment, especially the Circuit Breaker, leading to failure in power distribution. As such, analyzing transient overvoltage is critical for understanding its impact and for designing systems that can withstand such surges. This study investigates transient overvoltages at PT PLN (Persero) 150 kV Makale Tana Toraja Substation, calculating the highest possible transient overvoltage that could affect Circuit Breakers. The research employs a quantitative descriptive approach with an Ex-Post Facto design, using the lattice diagram method to analyze the transient overvoltage behavior. Findings reveal that the highest recorded transient overvoltage was 227.231 kV, with values decreasing as the distance from the lightning strike increases. Furthermore, calculations suggest that in the case of properly functioning arresters, transient overvoltage values at Circuit Breakers 1 and 2 are 512.33 kV and 542.514 kV, respectively. However, if the arresters are damaged, these values increase significantly to 1031.94 kV and 1028.814 kV. This study emphasizes the importance of maintaining functional lightning arresters to ensure protection system efficacy. By optimizing the design and operational parameters of protection equipment, this research contributes to strengthening the resilience of substations, ensuring the safety and reliability of critical infrastructure in areas prone to lightning strikes.

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
