PT. DELTA, as one of the contractors engaged in mining activities at PT. BETA, has exhibited suboptimal overburden production performance over the past year. During the last one-year period (January 2023 to December 2023), PT. DELTA's overburden production performance is often below the plan (target). This Final Project delves into the application of Lean Six Sigma methodologies to augment overburden productivity in the mining operations conducted by PT. DELTA. The primary objective of this Final Project is to meticulously examine the mining activities at PT. DELTA and assess how Lean Six Sigma principles can be strategically employed to enhance efficiency and productivity in overburden removal processes. A significant facet under scrutiny is the identification and elimination of non-valueadded activities that contribute to prolonged overburden removal times. The DMAIC (Define, Measure, Analyze, Improve, Control) framework, inherent to Lean Six Sigma, guides the systematic and data-driven approach adopted throughout the study.By proposing and implementing targeted improvements, the study aims to showcase the tangible impact that Lean Six Sigma methodologies can have on increasing productivity. In conclusion, this Final Project provides a comprehensive exploration of the application of Lean Six Sigma methodologies to elevate overburden productivity in the mining activities of PT. BETA, managed by contractor PT. DELTA. The insights, recommendations, and outcomes derived from this research not only contribute to the existing body of knowledge in Lean Six Sigma but also furnish practical solutions for enhancing efficiency and productivity in the dynamic and competitive landscape of the Indonesian mining sector.
