Abstract

Product quality is one of the keys to a company's success. Companies that pay little attention to quality will struggle to compete, impacting their future sustainability. This research was conducted at Putra Cendana Tempe Enterprise in Klungkung Regency to determine whether the company's quality control practices are optimal. This study used a quantitative descriptive research method. The data used were production volume, number of defects, and type of product defects for the period July 2025. Data analysis was carried out using the Statistical Quality Control using statistical tools, namely flowchart, check sheet, control chart, and fishbone diagram. The results of data analysis show that there are many points that exceed the upper control limit (UCL) and lower control limit (LCL) which indicates that the company's production process is still out of control. Factors that cause product damage include human factors, methods, materials, and machines/equipment.
