Abstract

An electrical energy audit is a systematic process of evaluating energy consumption in a building or facility in order to identify energy efficiency and potential savings. energy use and potential savings. This research aims to conduct an electrical energy audit in order to determine the intensity of energy consumption (IKE) and provide technical recommendations that support energy efficiency in the office of the Bantaeng Vocational and Productivity Training Center. The energy audit was conducted by collecting electricity consumption data from PLN billing records as well as direct measurements in the field. The analysis focused on the calculation of Energy Consumption Intensity (ECI) to assess the energy performance of the building. The audit results show that the intensity of energy consumption (IKE) for one year, the value of energy consumption intensity (IKE) for one year, the value is 12.8 kWh/m2/year which means it is still below the ASEAN-USAID standard of 240 kWh/m2/year. Likewise, compared to the IKE standard according to the Regulation of the Minister of Energy and Mineral Resources No. IX. Minister of Energy and Mineral Resources Regulation No. 3 of 2025 which is <99 kWh/m2/year with a total building area of 11,644 m2 > 5000 m2 is categorized as very efficient.

Abstract

Solar Power Plants (PLTS) are renewable-based electricity systems for areas not yet reached by the national grid. This study aims to design and test a small-scale PLTS system for lighting a farm house in Selayar Regency. The system consists of a 100 Wp solar panel, a PWM 10A charge controller, LiFePO4 batteries, and 30–40 W LED loads. The research method includes system design, assembly, and performance testing. The results show that the solar panel produced a voltage of 13.2–13.6 V, solar radiation intensity of 560–1235 W/m², and an average efficiency of 11.71%. The system meets daily energy needs of 1.260 Wh and provides lighting for 12 hours per night. This PLTS system proves effective as a clean energy solution for remote areas
