Analysis of Ceramic Quality Control in PT. XYZ Using Six Sigma and FMEA Methods

Abstract

Quality control is an integrated activity in the company to maintain and maintain the quality of products produced in order to run well and according to established standards. Quality control needs to be carried out at PT. XYZ, a manufacturing company that produces ceramics. The problem that occurs is the number of defective products found in the finishing process. Data collection is done by interview, field observation and documentation. The data used in this study is the amount of production from May to October. This study aims to find the DPMO value and how the most appropriate improvement efforts, with the six-sigma method through the DMAIC approach. Analysis to find the most dominant cause of defects is done with the fishbone diagram method, which is one of the methods/tools in improving quality. This diagram is also often called a cause-and-effect diagram. Based on the fishbone, the RPN value is calculated to determine the most dominant cause and the most appropriate improvement proposal.
