Abstract

This study implements the DMAIC (Define, Measure, Analyze, Improve, Control) method to reduce spoilage in coating machines at PT XYZ, addressing material losses and production inefficiency. The method systematically identifies and resolves issues, starting with defining the spoilage problems and setting improvement goals. In the measure stage, spoilage data is collected, yielding a sigma value of 3.54 ?, with a Pareto analysis revealing that 7.05% of spoilage results from wicket abrasion/wicket mark defects. The analyze stage employs a fishbone diagram and FMEA to uncover root causes, such as troubleshooting skills and the condition of the wicket and its chain. The improve stage implements solutions, while the control stage ensures ongoing monitoring and adherence to new SOPs. Post-implementation, the sigma value improved to 3.84 ?, demonstrating the effectiveness of the DMAIC method in minimizing spoilage and its applicability to other manufacturing processes.
