Abstract

An overhaul is a process of dismantling a problematic engine so that it can be examined more thoroughly. During the overhaul, the problematic engine components are replaced. The overhaul of the sphere gap setting of the semi-automatic high impulse voltage generation is also intended to maximize the K3 system and the level of accuracy when conducting research on impulse voltage generation. The current condition after the occurrence of damage to the automatic sphere gap adjustment machine. The sphere gap setting is done manually, causing the desired ball gap distance to be not very accurate, and the risk of work accidents is higher in the high voltage laboratory. In the first stage of work, an inspection and measurement were carried out to replace the capacitor and limit switch components because they could no longer be used. As well as improvements to the electromagnetic brake components. From the test results, it was found that the distance measurement was as expected and it can be proven that after an overhaul, the semi-automatic spacer can function normally again so it can make it easier to conduct high voltage impulse research. In addition, from a security point of view, it is better because the spacing between the balls is done outside the high-voltage impulse generation cage

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.
