Optimization O&M Cost of Coal Handling Port Facility from 30 – 48 MTPA

The challenge of O&M cost efficiency in the midst of increasing global demand for coal, which requires optimal cost management without reducing operational performance. The objective of this study is to determine the optimal O&M cost by analyzing key cost components such as fuel, heavy equipment, spare parts, labor, and infrastructure investment, and their impact on production achievement. The research used a case study approach with a combination of quantitative and qualitative analysis. Primary data was obtained through interviews and direct observation, while secondary data was analyzed using the Activity-Based Costing (ABC) method, simulation modeling, and regression to evaluate the impact of cost variations on production achievement. The results show that the optimal O&M cost for a production capacity of 30-48 MTPA is in the range of 10,568-11,970 IDR/ton, which is still lower than the market price. This optimization was achieved by mapping key cost components, including fuel, crusher and conveyor system maintenance, and labor. The application of the ABC method enabled the identification of areas of efficiency, resulting in more cost-effective operations without compromising facility performance. The implications of this research include improved operational efficiency, coal industry competitiveness, as well as the sustainability of port operations. The findings provide a strategic foundation for more effective cost management, especially in the face of demand fluctuations and operational challenges due to external conditions.
