This study was conducted to evaluate the quality of banana chips products at My Kripis by using the Check Sheet and Fishbone Diagram methods. The main problem found was the high rate of defective products, which reached 3.79% of the total monthly production. The largest type of defect was recorded as inappropriate banana ripeness during the frying process, which amounted to 18 kg out of a total of 37.2 kg of defective products. Data was collected through direct observation and interviews, then analyzed using an inspection sheet to identify the type and frequency of defects. Results showed that the dominant cause of defective products came from raw material factors, such as non-uniform banana ripeness and inconsistent slice thickness. A Fishbone Diagram was used to identify root causes from various aspects, including man, methods, machines, and materials. These findings served as the basis for recommendations to improve the production process, such as standardizing cutting procedures, training operators, and monitoring the quality of raw materials. This research confirms the importance of simple yet systematic quality control for MSMEs to sustainably improve product quality.

Product quality is described as the characteristics of a product that supports its ability to meet customer needs standards or manufacturer feasibility standards. This research was conducted on potato chip products at Osha Snack by analyzing the types of defects in potato chips and their causative factors. In this study, the method used is the seven tools method, namely fishbone diagram, pareto diagram, and flowchart diagram. In one month, 57 units of defective potato chips were obtained. The purpose of this study using the seven tools method is to find out the types of defects in potato chips and the factors that cause defects in the product to minimize the level of defects in the production period in the next period. Based on the data obtained, there are two types of defects in potato chips, including 35 units of product returns and 22 units of burnt chips and inappropriate potato cutting. On the application of quality chips.
