Kurnia Mustika Indah Lestari is the inner body of K56. In one month the product rejects amounted to 2.0%, which exceeds the tolerance limit set by the company, namely 0.5%. It is necessary to carry out research aimed at determining the root of the dominant problem that causes rejection of the inner K56 body and determining the quality improvement proposal. The method used is quality control with the DMAIC stage. The results of the research findings show that the dominant root cause of reject burry is that work instructions are not carried out (Method) and working in a hurry to quickly rest (Human). The reject scratch type is due to lack of skill (Method) and pursuing a lot of rest time (Human). The recommendation to improve the quality of the reject burry is to carry out work instructions, be more careful when loading the material into the dies, always clean the inside of the dies, checkman supervises the manpower of the production process so that it works according to cycle time. For the reject scratch type, it is to provide training for man power, give warning instructions for the placement of parts while running the process, set rules for working times that are not too fast, take advantage of spare time to clean the machine. \u0000Keywords: Quality, Reject, DMAIC (Define, Measure, Analyze, Improve, Control).","PeriodicalId":335059,"journal":{"name":"Journal of Industrial and Engineering System","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133617883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Die Casting is one of the departments that is important in the manufacture of motorcycle parts. In the Die Cating section, there are a number of types of defects that exceed the company tolerance standards. During the February to July period, 228 pcs of defect products were found. For this reason, it is necessary to determine the most dominant factor in the occurrence of defects and determine the proposed improvement of the root problem. PDCA is a useful tool for continuous improvement and FMEA or Failure Mode Analysis is a tool that is often used in quality improvement methods. FMEA serves to determine the consequences of failure associated with failure in the Crank Case LH. There are three types of defects found, namely Chipped, Cracked, Wrinkled. With pareto diagram, it is known that there are three types of defect Crank Case LH which are the most dominant, namely: 9.9% chipped, Crack 6.75%, Wrinkles 4.72%. aluminum & mold is too low, engine filling time is too long, Crank Case LH Cracks the surface of the rough molding machine, engine pressure is too large, Crank Case LH Machine wrinkles Less pressure.
