P PT. Harapan Mulya Putri is a manufacturing industry that produces cleaning equipment.Various cleaning equipment was produced, such as ashtrays, round fiber bins, and 120 literand 240 liter HDPE plastic bins, but in this study the focus was on round trash bins madefrom stainless steel because this is the product that is most commonly produced and still hasa high value of defects. The data used is production data for the period from January to June,where in that period there is a significant level of product defects with the highest defectpercentage of 10.86% while the company's tolerance is at 5%. The purpose of this researchis to improve the quality of waste products made from stainless steel. The stages carried outin this study were to identify the types of defects, the causes of defects and providesuggestions for improvements to the production process. In this study the method used is SixSigma and Fuzzy Analytical Hierarchy Process. The Six Sigma method has 5 stages,abbreviated as DMAIC, namely: define, measure, analyze, improve and control. In the Definestage, tools such as SIPOC diagrams and Critical To Quality (CTQ) identification are used.The types of defects found were body dents, scratches, spots, and rough covers. In theMeasure stage there are calculations with the P control chart as well as DPMO and sigmalevel. The initial DPMO value obtained is 3.422. In the Analyze stage, analysis of the causesof defects is carried out using tools such as pareto diagrams, fishbone diagrams, and failuremode effect analysis (FMEA). The results of the analysis process are defects with the highestvalue (Risk Priority Number) of 280. The next stage is Improve, where defects with thehighest RPN value are prioritized for proposed improvements using the Fuzzy AnalyticalHierarchy Process (Fuzzy AHP). Based on the results of the Fuzzy Analytical HierarchyProcess assessment, it was found that the improvement alternative with the highest totalweight was alternative 3, namely the machine must be cleaned regularly after use with a totalweight of 0.4322, alternative 2, namely the addition of material handling to facilitate producttransfer with a total weight of 0 .2048, and alternative 4, namely the establishment of aStandard Operating Procedure in handling products of 0.2041. After the Improve stage, thefinal stage in the form of Control is carried out to see whether the implementation of theproposed improvements has a positive impact on the company. The result of theimplementation was in the form of carrying out a Standard Operating Procedure with aChecklist for operator product handling carried out for 5 working days, with an increase inthe sigma level to 3.6061
