Enhancing Fuel Ratio Efficiency for Sustainable Operations in Pit KX Mining: DMAIC Methodology

Abstract

PT ABC is one of Indonesia’s largest coal mining businesses, and the mining. Pit KX is one of the company’s pits worked by contractors, and it has been mined since 2008. According to the company’s historical data from January 2022 to June 2023, overburden and coal production from Pit KX has decreased while fuel consumption has grown. Fuel is a major cost component in mining operations. The overall fuel cost represents around 35% of the company’s total operational cost. This study investigates the use of the DMAIC (Define, Measure, Analyze, Improve, Control) approach as a systematic framework for improving fuel ratio efficiency and promoting sustainable practices in pit KX mining operations. The DMAIC technique provides a disciplined pathway for discovering, assessing, and eliminating fuel-related inefficiencies. DMAIC offers a disciplined framework for improvement. By implementing DMAIC methodology, it can systematically identify and address inefficiencies in fuel utilization leading to reduced operational costs, minimized environmental impact, and enhanced sustainability of pit KX mining operations.
