Abstract

The function of the grounding system is to limit the voltage between equipment and the ground and neutralize the voltage that arises at the ground surface due to fault currents flowing in the ground. An unsafe grounding system can disrupt system reliability and human safety in the substation area. This research aims to simulate the design of a substation grounding system with the influence of variations in location and number of electrodes installed in grids and rods in swampy soil conditions with different soil resistivity values. The impact of these parameters is on the resistance value, touch voltage, and step voltage at a weight of 70 kg by using the CYMGRD application as a medium to see the effectiveness and optimization of whether the substation grounding system with variations in the outside area and variations in the number of electrode rods meets the requirements without exceeding safe limits on systems or humans. This grounding system design is designed for two cases, namely case 1: the maximum touch voltage and maximum step voltage values exceed the permitted touch voltage and maximum step voltage, so conditions like this are included in the criteria for being unsafe and can endanger personnel in the field. Case 2: the touch voltage and step voltage values are smaller than the permitted touch voltage and step voltage values, so this design is included in safe conditions and meets the criteria for a good and safe grounding system.

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.
