PT XYZ is a shoe manufacturing company that in its production process experienced a defect rate of 5.3% of rubber outsoles, exceeding the company's tolerance limit of 3%. This study aims to identify and reduce these production defects. The types of defects found include rubber bleeding, cosmetic defects, overcure/undercure, different colored rubber, and dirty rubber. The approach used is Six Sigma with the DMAIC (Define, Measure, Analyze, Improve, Control) method. In the Define stage, critical defects are identified using the SIPOC Diagram. The Measure stage involves collecting production data and calculating the Defects Per Million Opportunities (DPMO) value and sigma level. In the Analyze stage, the root causes of defects are analyzed using the Fishbone Diagram. Next, the Improve stage is carried out by implementing corrective steps through the Five M Checklist and Five Step Plan methods. Finally, the Control stage ensures continuous improvement through routine monitoring and the creation of daily audit checklists. The results of the study showed a decrease in the defect rate and an increase in the sigma level from 3.8 to 4.02. This proves that the implementation of Six Sigma is effective in improving product quality and reducing the number of defects in the rubber outsole production process at PT XYZ.
