Abstract

Mechatronics, as an interdisciplinary field integrating mechanical, electrical, computer, and control engineering, provides innovative solutions for energy and environmental challenges in urban regions. This study conducts a systematic literature review and meta-analysis using open access datasets to evaluate solar energy potential, electricity reliability, and air quality in Medan, North Sumatra. Results show that the city has strong solar irradiance levels, averaging 5.75 kWh/m²/day, indicating substantial feasibility for photovoltaic deployment. Electricity reliability, assessed through SAIFI and SAIDI indicators, is more stable in Medan compared with other Indonesian cities, offering a favorable foundation for renewable integration. Air quality analysis reveals moderate conditions, with PM2.5 concentrations averaging 28 µg/m³, slightly above World Health Organization standards, yet lower than Jakarta and Pekanbaru. Across all dimensions, mechatronics applications, including smart grid automation, intelligent inverters, IoT-based environmental sensors, and robotics-assisted monitoring emerge as crucial tools to bridge research and implementation gaps. The study identifies limited adoption of techno-economic feasibility analysis, localized reliability assessments, and distributed sensor networks in Medan, which restricts practical deployment. Future research should emphasize mechatronic frameworks such as predictive control, cyber-physical systems, and stochastic modeling to improve resilience. Policy recommendations highlight the need for targeted incentives, pilot projects, and interdisciplinary collaboration. Overall, this work positions mechatronics as a key enabler for sustainable energy transition and environmental management in Medan, offering insights applicable to other rapidly urbanizing regions in Indonesia.

Abstract

This study presents a comprehensive analysis of a designed three-phase electrical distribution system for a dedicated Heating, Ventilation, and Air Conditioning (HVAC) plant. Based on data extracted from a single-line diagram and load schedule, a significant inherent load imbalance of 9.15% was identified. This paper outlines a four-stage methodology to investigate the consequences and propose a solution. The methodology includes a system audit, simulation-based consequence analysis of energy losses and motor derating, design of a no-cost phase-swapping mitigation strategy, and a techno-economic evaluation. The proposed passive balancing reduces the load imbalance to 1.32%. The study highlights the critical importance of meticulous load scheduling during the initial design phase to enhance system efficiency, ensure equipment longevity, and achieve significant operational cost savings without capital expenditure.

Abstract

The rapid growth of global energy demand and the urgent need to reduce greenhouse gas emissions have accelerated the transition toward renewable energy technologies, with solar photovoltaic (PV) systems playing a central role. In Indonesia, high solar irradiation provides significant potential for PV adoption, yet challenges remain in human resource capacity and technical readiness, particularly in rural areas where off-grid systems are critical. This study presents the design, development, and testing of a 200 Wp off-grid PV training module aimed at bridging the gap between theoretical knowledge and practical skills in renewable energy education. The module integrates two 100 Wp PV panels, a 100 Ah lithium-ion battery, an MPPT charge controller, and a 500 W pure sine wave inverter, all mounted on a modular acrylic platform to enable repeated assembly and disassembly for training purposes. Experimental testing under tropical conditions demonstrated stable PV output (Voc 19.8–21.5 V, Isc 4.8–5.4 A), efficient battery charging within 8 hours to full capacity, and reliable discharging performance sustaining DC loads for 18 hours and AC loads for 12–14 hours. Inverter efficiency averaged 92%, with minimal waveform distortion under typical loads. These results confirm the module’s reliability and educational value, offering a robust platform for vocational training and community-based capacity building. The study contributes to Indonesia’s renewable energy transition and supports Sustainable Development Goal 7 by enhancing technical education and workforce readiness for solar PV deployment.
