P T. Biggy Shining is as one of the pioneers in the manufacture of plastics in Indonesia . Problems that occur in the quality of production inmoldlabeling which is based on the results of the production month of December 2018 - February 2019 with an average product defect by 7.62%. The purpose of research is to identify the characteristics of the disability , identify the cause of the failure and determine the proposed improvements to the product that the methods of Six Sigma with stage D efine, M easure, A nalyze, I mprove and C ontrol . Stages define aims clicking identification in the process of production of the products Lunch Box using map process operation , SIPOC diagrams, and C ritical t o Q uality . Stages measure , in doing calculations disability products by map control , calculation DPMO and nil ai sigma amounted to 12416.7 and 3.74 . Phase analyze identify the type of failure process and the cause of the failure of the process of production of the by Failure Method and Effect Analysis . Stage improve for the determination of the plan of improvement of quality in the manufacture of form checks daily machine , form scrap area, and standard operational procedures engine injectionblowmolding based problems by using brainstorming . Phase control in the settlement with the methods of Six Sigma do calculations map controls are already in implementation . Calculation DPMO and the value of sigma which is already implemented at 10000 and 3.83 . Improvements are already implemented experiencing an increase in the level of sigma and results of production in the month of April 2019 obtained a percentage of product defects amounting to 4.96%
