Assuring product quality has been always a main concern of a production process. PT IGP Internasional Sleman is a company that produces Printed Tissue Paper. This company's defect tolerance limit is 2%. Based on early observations, the defect rate reaches 5.2%. The Eight Disciplines (8D) method was used to solve the problem. First, the team was built to engage all related divisions in the project. Then, Failure Mode and Effects Analysis (FMEA) was carried out to sort the problems. Root Cause Analysis using Fishbone diagram was also used to find the causes. Proposed improvements to reduce defects have been implemented. There are adding Rotogravure machine operators, conducting supervision/inspection by production leader, and providing socialization related to the importance of product quality and production. The implementation has successfully reduced the defects to fulfill the company’s standard.
