Abstract: This study aims to analyze and reduce the number of defective products (defects) in the process of quality receiving packing door armrest panels at PT XYZ using the Six Sigma method with the DMAIC approach (Define, Measure, Analyze, Improve, Control). The defect problem was found in the Plant 3 area which had an impact on the non-conformity of product quality received by customers. Data was obtained through direct observation, historical problem data, and cause analysis using cause-and-effect diagrams and 5 Why Analysis. The results of the Define stage showed that the dominant defect type was internal defects due to dust particles. At the Measure stage, it was found that 87.5% of defects originated from internal factors. Analysis was conducted by identifying the root cause through the DMAIC approach. The Improve stage includes implementing corrective actions such as improving checking methods, improving cleaning aids, and reviewing packaging standards. Monitoring was carried out at the Control stage for three months and the results showed that no more defects occurred after the improvements were implemented. This research shows that the DMAIC method is effective in identifying and reducing the number of defects in the packing process at PT XYZ.
