In this case, we discuss efforts to control the quality of TR 7864 fabric products at PT XYZ. In terms of product quality, many defects were found which was quite high. This situation makes the company unable to meet the production targets that have been set. This study aims to analyze the existing quality control in the company. We use the Statistical Quality Control method to analyze product quality control. The quality of the studied fabric products is not within the control limits, so it is necessary to improve quality control efforts. Based on field observations, the starch cooking method used was not in accordance with the characteristics of the chemicals used. In addition, the shuttle machine used to weave cloth is very old so it often gets stuck and some components are no longer functioning. The application of process inspection in the production process is not given much attention. Whereas inspection in every production process really needs to be done properly as an effort to control quality. The need for various efforts to improve quality control is aimed at reducing the percentage of defective products so that they can reduce the cost of company losses due to defective products.
