Analysis of Energy-Saving Opportunities at SMKN 3 Kuningan

Abstract

This research presents the results of an energy audit at SMKN 3 Kuningan, which aims to identify energy saving opportunities in the school's electrical system. The audit focused on two main energy consumption systems, lighting and air conditioning (AC). The analysis was conducted based on electricity consumption data and Energy Consumption Intensity (IKE) standards. The results show that the lighting system still uses conventional TL and incandescent lamps, which waste energy. Replacing with energy-saving LED lamps can save around 571 kWh per month. In addition, the AC units used mainly have low efficiency. Replacing with energy-saving AC and adjusting operating hours results in additional savings of 5,718.29 kWh per month. Overall, the school has the potential to reduce electricity consumption by 6,289.29 kWh per month. The implementation of this recommendation is also able to reduce the IKE value from 105,321 kWh/m²/year to 103,924 kWh/m²/year, closer to the national efficiency standard according to SNI 03-6197-2000 and the regulations of the Ministry of Energy and Mineral Resources. This research emphasizes the importance of regular energy audits in educational institutions as a strategic step in operational cost efficiency and contribution to environmental sustainability.
