This study investigates quality control performance of PAD products on the Urethane production line at PT ABC, an automotive manufacturing company. The primary issue identified is a high defect rate, dominated by hardness defects (84.84%) and followed by weight defects (15.16%), indicating unstable production quality. To address this issue, the Six Sigma methodology with the DMAIC (Define, Measure, Analyze, Improve, Control) framework was employed. In the Define phase, Critical to Quality (CTQ) characteristics were determined, namely hardness and weight. The Measure phase involved analysis of historical production data using control charts (I-MR), along with the calculation of Defect Per Million Opportunities (DPMO) and sigma levels. The results reveal that the process capability remains below the Six Sigma target. The Analyze phase utilized Pareto and fishbone diagrams to identify root causes related to machines, materials, methods, operators, and the environment. Improvement strategies were proposed in the Improve phase, while the Control phase focused on sustaining process improvements through standard operating procedures and continuous monitoring.
