<![CDATA[This study aims to identify the dominant defect type, determine the main causative factors of defects, and measure the defect reduction rate after improvement implementation based on the integration of Six Sigma (DMAIC) and Failure Mode and Effect Analysis (FMEA) methods. The research methodology follows the DMAIC stages: Define using a SIPOC diagram to map the production process; Measure using DPMO calculation, sigma level, and p-control chart; Analyze using Pareto diagram and fishbone diagram; Improve using the 5W+1H method; and Control through production process supervision. The analysis results show that the dominant defect type is cut QR code (28% of total defects). The average DPMO value is 3,519.48 with a sigma level of 4.20. FMEA analysis identified three priority causes with the highest RPN: not implementing the cutting SOP (RPN=336), incorrect print layout settings (RPN=315), and no alignment check (RPN=288). After implementing improvements in April 2026, the defect percentage successfully decreased to 0.96%, DPMO decreased by 60.97% to 1,373.63, and the sigma level increased to 4.49. Internal failure costs were reduced by 71.0%, from IDR 802,000 to IDR 234,000.]]>
