Abstract

The protection system in electrical engineering is a crucial component in maintaining electrical reliability. The protection system is a vital component that needs attention. Its utility not only serves as a parameter for the reliability of the electrical system but also as a safeguard for electrical system devices, starting from power suppliers (Power Plants), interconnection networks, transmission networks, to distribution networks. In Indonesia, with the unique dynamics of the domestic market, periodic evaluation of relays becomes important. This study investigates the current status and dominance of relay usage in Indonesia. Using a literature study method, we broadly identify the functions, utilities, and applications of Over Current Relay (OCR), Ground Fault Relay (GFR), Differential Relay, and Reverse Power Relay in Indonesia's electrical system. This literature study outlines several types of relays in Indonesia and their dominant usage in the electrical system, providing insights for readers and institutions using relays in Indonesia's electrical system. The implications of this literature study are to broaden the knowledge of the authors and readers and to encourage continuous innovation. With an understanding of the types of relays in Indonesia's electrical system, strategic steps can be taken to improve the reliability and efficiency of the electrical protection system in Indonesia.

Abstract

All human activities depend on electrical energy. The use of new renewable energy in Indonesia is still around 15%, even though Indonesia has great potential for new and renewable energy sources, especially water-based alternative energy. PLTMH is one example of the utilization of new renewable energy from water sources. Turbine is one of the important components in PLTMH. This study aims to conduct a literature review on turbine types and trends in PLTMH design publications using the systematic literature review method.  The review results show that the crossflow type impulse turbine is most dominantly used in PLTMH, followed by the Pelton type. Other turbine types such as Francis, Vortex, Archimedes Screw, and undershot are used less frequently. The publication trend peaked in 2020, then declined moderately in the following years. As of May 2024, there are no new studies, indicating a change in focus or a decline in interest.

Abstract

Efficient energy management in Internet of Things (IoT) devices is critical in dynamic, resource-constrained operational environments. This study proposes the Queen Honey Bee Migration (QHBM) optimization algorithm for managing Li-ion battery performance in IoT systems, employing the Shepherd battery model to simulate the nonlinear discharge behavior under varying load conditions. Three simulation scenarios of increasing complexity (5, 10, and 20 monitoring points) are used to represent urban operational dynamics. The performance of QHBM is quantitatively compared with four conventional optimization algorithms seperti Particle Swarm Optimization (PSO), Differential Evolution (DE), Genetic Algorithm (GA), and Firefly Algorithm (FA). Results show that QHBM maintains a current range of 3.80–5.20 A and a voltage range of 3.65–3.95 V, with State of Charge (SoC) predictions between 75–98%. It also achieves the fastest computation time (0.42–1.20 seconds) and demonstrates more stable performance under high-load dynamic scenarios compared to the other methods. This approach provides an adaptive and efficient optimization framework to support energy-aware decision-making in IoT systems operating in energy-constrained urban environments.

Abstract

The teacher professional education program requires prospective physics teachers to demonstrate integrated academic, pedagogical, social, and personal competencies. However, current evaluation practices remain dominated by traditional multiple-choice tests that primarily assess lower-order cognitive skills and fail to capture critical thinking, problem-solving, and reflective abilities. This study aims to develop a problem-based professional competency test designed to predict the academic success of the teacher professional education program students in physics. The research employed a Research and Development (R&D) approach with a modified Borg & Gall model, covering needs analysis, design, expert validation, pilot testing, revisions, and field trials. The participants were 57 physics students of the teacher professional education program on universitas in Malang at 2025. The initial instrument consisted of 35 items, which were refined to 25 valid items through rigorous analysis of validity, reliability, item difficulty, discrimination power, and distractor effectiveness. Findings revealed that all 25 items were valid, with an instrument reliability coefficient of 0.788. The distribution of item difficulty was dominated by easy to moderate levels, ensuring a balanced measurement range. These results highlight that a problem-based professional competency test can serve as a valid, reliable, and contextually relevant evaluation tool. It not only aligns with the demands of higher-order thinking but also reflects the pedagogical readiness required of future physics teachers.

Abstract

The level of the company's ability to produce a product from the performance quality index is one of the performance indicators. The performance quality index shows a decrease in employee performance, where performance appraisal in a company shows the profitability and sustainability of the company's operations. This study aims to analyze the effect of commitment, work environment, and compensation on employee performance with mediation of job satisfaction at PT Sai Apparel Industries. This research uses quantitative methods with stratified random sampling techniques by giving questionnaires to the entire population of two hundred employees, and one hundred and thirty- three can be processed. This research uses the Structural Equation Model-Partial Least Square (SEM-PLS) with the SmartPLS 3.2 application. The results found that commitment has no effect on job satisfaction. However, it has a positive and significant effect on employee performance. Work environment, job satisfaction, and compensation have a positive and significant effect on job satisfaction and employee performance. In addition, job satisfaction cannot mediate the relationship between commitment and compensation, but the work environment has a positive and significant effect on job satisfaction and employee performance. job satisfaction has an impact on the work environment and employee performance.

Abstract

This research focuses on optimizing the Particle Swarm Optimization (PSO) method in switching modulation to reduce total harmonic distortion (THD) in a 7-level Cascade H-Bridge Multi-Level Inverter (MLI) topology with triple voltage boosting gain. MLI Cascade H-Bridge is an inverter topology that is widely used in power conversion applications because of its ability to produce high voltage output with low harmonics. However, the resulting THD is still a major challenge in improving power quality. In this research, the PSO method is applied to find optimal parameters in switching modulation that can minimize THD. The research results show that the PSO method succeeded in reducing THD significantly with a THD value of 7.80% whereas the previous THD was 17.27%. The implementation of PSO in switching modulation is expected to be an effective solution for inverter applications in industry and power systems. The THD value from the PSO optimization is stated to be in accordance with IEEE 519 standards with a maximum permitted THD of 8%. This value is better than previous research, namely 17.27%.

Abstract

The aim of this research is to examine the influence of Return on Assets (ROA), Return on Equity (ROE), Net Profit Margin (NPM), and Earning per Share (EPS) on Share Prices (HS) and the role of EPS in organizations or companies in the construction and housing sectors. /property and real estate. The decision to select this study was based on the importance of this sector as an indicator of the country's economic health. Data was obtained from the annual financial reports of these organizations registered on the IDX from 2019 - 2021, using a purposive sampling technique. Quantitative method with a descriptive approach and path analysis to analyze data using SPSS software. The research results show that these three factors have a partial effect on share prices, with earnings per share (EPS) proven to be able to mediate the effect of return on assets (ROA) on share prices (HS). However, earnings per share (EPS) was not able to mediate the effect of return on equity (ROE) and net profit margin (NPM) on share prices (HS). These results indicate that investors in the property and real estate sector consider profitability and operational efficiency as indicators of company performance that have the potential to influence share prices. This research has several limitations, such as company coverage, the adjusted r-square value which influences share prices by 35.4%, and has not considered other factors that can mediate return on equity (ROE) and net profit margin (NPM) on share prices.
