Analysis of Carton Packaging Quality Control Using Statistical Quality Control Methods at PT XYZ

This research focuses on analyzing the quality control of cardboard box packaging at PT XYZ using the Seven Tools method. The main problem faced by the company is the high level of defects in the cardboard box products produced, which has a negative impact on production efficiency and customer satisfaction. The aim of this research is to analyze the main causes of defects in cardboard box products and provide suggestions for improvements that can be implemented by companies. The method used in this research is Statistical Quality Control (SQC) which involves the use of Seven Tools, namely check sheets, Pareto charts, fishbone diagrams and control charts. Using these tools, data regarding defects is collected, analyzed, and interpreted to identify the main causal factors of quality problems. The analysis results show that certain factors, such as the quality of raw materials, production processes, and operator skills, have a significant contribution to the occurrence of defects. Based on these findings, this research proposes several improvements that can be implemented by PT XYZ to improve the quality of their cardboard box products. Proposed improvements include increasing control over the quality of raw materials, skills training for operators, and implementing stricter standard operational procedures in the production process. By implementing this proposed improvement, it is hoped that PT XYZ can reduce the level of defects in their products, increase production efficiency, and increase customer satisfaction.
