Abstract

This study investigates the performance and energy efficiency of a three-phase induction motor controlled by a Variable Speed Drive (VSD) in a fatty acid pump system at the Permata Group processing plant. The research is motivated by the increasing need for energy savings and operational reliability in continuous industrial processes where pump load profiles are highly dynamic. The objective of this study is to evaluate the effectiveness of VSD implementation in reducing energy consumption and improving motor operating characteristics under real plant conditions. Data were collected during actual production cycles through direct measurement of electrical and mechanical parameters, including current, voltage, frequency, torque, flow rate, and power consumption. The analysis compares the performance of the pump system before and after the application of VSD, using descriptive statistical analysis and graphical evaluation of motor behavior under various load conditions. The results demonstrate that the application of VSD significantly reduces energy consumption at partial loads while maintaining stable pump output and minimizing mechanical stress. The motor also shows improved operating efficiency and lower thermal loading compared to constant-speed operation. These findings indicate that VSD-based control offers a practical and cost-effective solution for industrial pump systems, especially in fatty acid processing operations where flow demand fluctuates during production. The practical implications are substantial, highlighting opportunities for energy conservation, equipment longevity, and process optimization without compromising product quality or throughput, making the system suitable for broader adoption in similar industrial environments.

Abstract

The use of rooftop solar power plants is one of the strategic solutions to support the energy transition and increase use of renewable energy in the industrial sector. This study aims to analyze the potential and performance of rooftop solar power plants at PT. Waruna Nusa Sentana building located in Medan City, North Sumatra, using a simulation approach based on HelioScope software. The analysis was carried out by utilizing Typical Meteorological Year weather data and technical parameters of the Photovoltaic (PV) system designed according geographical conditions and tropical climate of the study location. simulation results show that rooftop solar power system with an installed capacity of 47.36 kWp is capable of producing 66,699 kWh of annual electrical energy with a specific yield of 1,408.3 kWh/kWp/year. The system performance evaluation resulted in a performance ratio of 80.2%, indicating that the rooftop solar power system works efficiently and is in the good performance category for tropical regions. Loss analysis indicates that the largest energy losses come from the effects of cell temperature, followed by losses due to module mismatch, reflection, and losses in the inverter and AC system. Manual calculations performed as analytical verification demonstrated consistency with the simulation results, thus strengthening the validity of the approach used. This study demonstrates that the implementation of rooftop solar power plants in industrial buildings in Medan City is technically feasible and can be used as a reference in the planning and development of rooftop solar power plants in tropical regions with similar climate characteristics
