Analysis of the cause of the defect packaging of capsule products using six sigma: A case study (PT SM)

Abstract

This research aims to manage the amount of defective packaging of capsule products in the department of capsule product at PT SM. It is important because the number of defective packaging of capsule products is high and exceeds the limits of maximum, i.e. 5% of the total production. In addition, the defective packaging of capsule products cannot be reworked and will cause losses in terms of time and finances. This research uses the Six Sigma method to find out the capabilities of the production process from the defective packaging of capsule products. Application of the method of Six Sigma through DMAIC process to eliminate the number of defective products and Fishbone diagram is used to identify the cause of the defect and provide recommendations on improvements to the production process. The data for this research is the amount of production, defective packaging of capsule products and interviews with the department of quality control, department of capsule product and operator. Data processing using Six Sigma methods showed that the value of sigma is 3.41σ with the number of DPMO is 27,951.202. Using Fishbone diagram, there are 9 causes of the defective packaging of capsule products.
