Abstract. Canning fish is a processed fish product that has gone through a processing stage, packaged in cans and given heat to ripen fish and other fillings and kill spoilage microbes. During the fish canning process there is product damage caused by several factors such as the production process that is not in accordance with the procedures, poor machinery and equipment, and unsupportive environmental conditions. One of the main causes of damage to fish canning products is cans damage which results in products being contaminated with microbes so that the contents of the cans will experience changes in color, taste and odor. Product damage needs to be minimized by carrying out quality control. Product quality is the most important aspect for companies to survive in the midst of competition between companies. One of the efforts that can be used to maintain product quality is the Statistical Quality Control method. This method can be used to analyze, manage and improve non-standard processes using a statistical approach. SQC has the ability to describe process abnormalities, see the pattern of increasing/decreasing processes in the process, so that corrective action can be taken and even preventive action before the problem actually occurs. The purpose of this study was to determine the quality of fish canning products from the level of product damage using the Statistical Quality Control method and to determine the causes of damage to fish canning products. The study was conducted using the Statistical Quality Control method with the stages of making a check sheet, histogram, control chart, and finally making a causal diagram to determine the cause of product damage. Based on the results of the analysis of calculations using the control chart for 26 days of observation, it is known that there is still damage that is outside the upper control limit which indicates a deviation and based on the analysis of the causal diagram of the factors that cause deviations, namely machines, materials, methods, humans and the environment.
