Markaz Souvenir is a business that produces various types of souvenirs, including ceramic mugs. However, there is a significant production failure problem. This study aims to identify and minimize product defects at Markaz Souvenir using the Six Sigma method and Failure Modes and Effects Analysis (FMEA) analysis. The results showed that the defect data was normally distributed with a failure rate of 482 units, a Defect Per Million Opportunities (DPMO) value of 22790, and a sigma level of 3.5, which is still at the Indonesian industry average. FMEA analysis identified three main types of defects: surface scuffing, logo fading, and surface unevenness, with the main causes being suboptimal machine conditions and low-quality raw materials. The highest Risk Priority Number (RPN) value was 112 for the logo fading defect. Suggested improvements include regular machine inspections, the use of better quality raw materials, and increased lighting intensity in the production area. In addition, the application of the Kaizen method with 5-S is proposed for continuous improvement. The 5-S steps involve organizing work areas, cleanliness, and consistent application of standards to improve product quality and production efficiency.
