Abstract

This research is focused on collared and T-shirt products on the garment industry with various types of clothing, especially for the upper middle market segment. High quality products that meet consumer needs are highly expected in today's competitive era. The results of observations of the products in this company found that there were many defects. Types of defects include dirty defects, holed, cutted and oblique defects. The method used to reduce defects is the six sigma method with fishbone diagram analysis, why-why analysis, and FMEA to improve product quality with the research objective of identifying the largest types of defects that occur in the production process, identifying factors that influence the biggest defects in the production process, providing suggestions for improvements using the application of six sigma with the DMAIC (Define, Measure, Analyze, Improve, Control) stages which aims to reduce defects in the production process. The DPMO value obtained was 13619.5 for collared shirts and 15376.3 for T-shirts with a sigma level value of 3.71 for collared shirts and 3.66 for T-shirts, which is still far from what was expected. Suggestions for improving quality are making Checksheets, providing training to operators, scheduling machine maintenance and replacing equipment with more appropriate equipment.
