Abstract
The medical industry currently maintains very high quality standards for medical products such as surgical sutures. PT XYZ, as a renowned manufacturer in this industry, faces challenges in reducing the defect rate of surgical suture products. This research focuses on surgical suture products produced by PT XYZ. The issue arises from the production results of surgical sutures conducted from January to March, during which a significant level of production defects was observed. The research aims to improve the quality of the packaging of surgical suture products by identifying the causes of defects in the packaging production process at PT. XYZ. It involves identifying the stages of the packaging production process to reduce defective packaging and implementing improvements, as well as providing suggestions for improvements in the packaging production process for surgical sutures at PT. XYZ. The Six Sigma method, specifically the DMAIC approach, will be used for this research. In the Define phase, tools such as the Supplier, Input, Process, Output, and Customer (SIPOC) diagram are used, along with the identification of Critical to Quality (CTQ) factors. The Measure phase involves calculations using P control charts, C control charts, as well as DPMO and sigma levels. During the Analyze phase, an analysis is conducted related to the causes of failure using tools such as the Pareto diagram, fishbone diagram, and Failure Mode Effect Analysis (FMEA). The next phase is Improve, where, based on the FMEA findings, defects with the highest Risk Priority Number (RPN) include torn cardboard, inconsistent color, and damp cardboard. Therefore, proposed improvements for cardboard defects are suggested using the 5W 1H analysis. Based on the 5W 1H analysis, it is found that the proposed improvements for torn cardboard, inconsistent color, and damp cardboard include increasing the frequency of replacing cutting machine blades, using cleaning tools for printing machine molds, and imp
