Analysis of Factors Causing Production Defects using the Six Sigma Method and Statistical Process Control in PT Daiho Indonesia

Abstract

The problem that often occurs in manufacturing companies in Indonesia is product defects. To achieve high-quality standards and meet standards, it is necessary to identify problems that cause defects in a product so that appropriate solutions or actions can be found to overcome these problems. This research is used to analyze production defect factors and how to resolve them using Six Sigma, which consists of the Define, Measure, Analyze, Improve, Control process, which can make it easier to solve problems and determine the sigma level before and after taking corrective action. In this research, researchers also used Statistical Process Control Tools (SPC), which were used to control, analyze, manage, and make improvements. Based on the results of the analysis, production defects are caused by human factors, materials, methods, machines, and molds. The results of research using the Six Sigma method and Statistical Process Control Tools (SPC) can increase the sigma value to 4.68 (5-sigma) and reduce the percentage of defects by 0.47%.
