development of technology and modern life and has a significant impact on improving energy performance in equipment or systems that use very large amounts of energy. This study was conducted using the ISO 50002:2014 method, which is a standard for defining minimum requirements that lead to identifying opportunities to improve energy performance such as determining EnPI (Energy Performance Indicator), determining SEU (Significant Energy Use), and measuring energy performance in equipment that uses energy. In the Company's activities, the energy consumed is electrical energy of 93.88% and solar power of 6.12% with Significant Energy Uses (SEU) being the HVAC-1 system (22.92%) and HVAC-2 (19.52%). And the other largest electrical loads are non-UPS and lighting (17.81% and 14.64%). The EnPI value for activities ranges from 0.0031-0.0049 GJ/kL with an average energy cost of Rp. 49,368,512,-/month and productivity cost intensity of Rp. 1,176.99,-/kL. For office activities, the average is Rp. 8,496,860,-/month with energy cost intensity of Rp. 24,207.58,-/m2/month. To improve optimal energy performance, the Company can target the EnPI value in the range of 0.0022 GJ/kL with a B30 distribution value of 47,000-53,000 kL/month. This performance improvement can be done by improving the quality of electrical voltage, replacing lamps in the work space, and managing energy in the air conditioning system.
The analysis that will be conducted in this study is able to manage and utilize energy at the Fuel Oil Terminal so that a picture of the performance of energy user units is obtained so that the potential for increasing energy performance can be known. In addition, this study also provides efficiency values on SEU (Significant Energy Used) equipment so that an EnPI (Energy Performance Indicator) picture is obtained which can be used as a reference for optimizing performance in productivity activities[10].
2. METHODOLOGY This study uses quantitative methods[11]. Quantitative approaches are used to analyze a phenomenon systematically based on secondary and primary data. In this study, for historical data on energy use and production, researchers use statistical techniques. For the analysis of Specific Energy Consumption (SEC) & Energy Performance Indicators (EnPI), energy consumption data will be collected then plotted in a table in MS Excel and then analyzed for correlation using the linear regression method. Secondary data collection is based on historical data on energy use and production at the BBM Terminal for the last 3 (three) years and data on equipment specifications that use significant energy. While primary data collection is carried out by measuring electrical and thermal parameters and light intensity to obtain actual data on conditions in the field so that accurate and real information is obtained.

1.INTRODUCTION
3. RESULTS AND DISCUSSIONS
As environmental awareness increases, energy conservation has become a frequently discussed topic. Energy conservation is not only an effort to reduce energy use, but also an inseparable part of the world's efforts to avoid the negative impacts of global warming and climate change. The Indonesian government through Government Regulation Number 33 of 2023 concerning Energy Conservation has regulated the implementation of energy conservation. Referring to Government Regulation of the Republic of Indonesia No. 33 of 2023, energy conservation is a systematic, planned, and integrated effort to conserve state resources and increase the efficiency of their use. Energy conservation can be achieved through efficient use of energy, including by implementing energy-saving behavior. Energy conservation is very important because the impacts of global warming and climate change are increasingly visible.
