Abstract. The industrial competition requires companies to produce high-quality products, but the phenomenon is that companies still produce products that do not meet specifications and are returned by customers. This is the basis for conducting research aimed at analyzing the implementation of quality control, knowing the main defects of the product, and making improvements to reduce or eliminate problems during the production process using the Six Sigma approach with steps: Define, Measure, Analyze, Improve and Control. The research sample is the result of the final product inspection in April - September 2019. The results of the study indicate that the implementation of Quality control has been carried out but not maximally, with the root causes of the main defects being method, material, and machine. CTO in this research are: foreign body contamination, leak packaging, product temperature exceeds the standard, over drip, and thick fat. After improving, there was an increase in sigma level from 3.48 (performance baseline) to 3.83. Control is carried out to maintain consistency of corrective actions by regular briefings to operators, increasing GMP training, 5S, and product knowledge, standardizing SOP changes, adding necessary tools, and controlling preventive maintenance implementation.
