PT Bumi Merapi Energi (BME) faces challenges in optimizing the use of industrial diesel fuel for its transport fleet, which is crucial for operational cost efficiency. The company relies on 30-ton class dump trucks to transport coal, so planning fuel consumption in line with production targets is a top priority. This research was conducted at the Kungkilan Block mining site of PT BME, which is administratively located in Muara Maung Village, West Merapi District, Lahat Regency, South Sumatra. The coal loading process in the pit area uses a loading tool in the form of a Hyundai K40 excavator. The effectiveness of this operational activity is greatly influenced by various factors, including dynamic work area conditions, the applied loading methods and patterns, and the cycle time of the loading equipment. Analysis of these factors is important to understand the productivity of the equipment and the required fuel consumption. This study calculates the total actual fuel consumption of the Renault K40 dump truck unit. Based on operational data during day and night shifts, it was found that the total diesel fuel consumption for one unit reached 134,910,650 in relevant units (e.g., Rupiah or liters, depending on the original context of the study), which highlights the large energy costs in the production cycle.
