Abstract: This study aims to find the type of defect, along with find the main causes and providing suggestions for improvements in reducing the number of failed products in production processes of firing sections. This study uses a Six Sigma methodology approach with tools such as Fishbone diagrams, Pareto diagrams, Brainstroming and Histograms. This research is a quantitative descriptive exploratory method. The results of this study indicate the types of product failures, namely Skirt Lip Crack, Inner Skirt Crack and Broken Body. Then there are several causes of product failure: the auger in the pugmill machine is worn, the dimensions of the Honggote (HG) shape in the forming and seizure sections are not matching, vacuum finishing is not stable, and there is no measurement of the twist of the Yobigote (YG) twist. Then, corrective actions were taken in the form of repairing the extruder and finishing machines, training the operators, making new SOPs, making checksheets and checklists for control. The conclusion of this research is that quality control using the six sigma method can reduce the rejection level and increase the six sigma level. The suggestion is the need for further research to be able to increase the six sigma level.
