Abstract

Quality control is a vital process to ensure that products consistently meet established standards and maintain customer satisfaction. This study examines the implementation of quality control methods in the production of frozen cooked skipjack loin, a key product in the canning and freezing fish industry. Beyond compliance with quality assurance systems such as Good Manufacturing Practice (GMP) and Hazard Analysis and Critical Control Points (HACCP), the industry must adopt rigorous quality control approaches to minimize product defects. Using the Seven Tools of Quality—namely the fishbone diagram, check sheet, Pareto diagram, and control charts—this research aimed to identify major sources of product defects and evaluate quality performance. The analysis revealed several types of recurring defects, with one particular defect being significantly dominant. Furthermore, control chart analysis indicated that the product quality was outside the acceptable control limits, signaling the presence of systematic issues in the production process. These findings highlight the importance of continuous quality improvement efforts to ensure product consistency and excellence.

Abstract

Fishery commodity distribution system has not been widely studied. Cold chain system must be applied in fishery product distribution system. The study of the cold chain system will be discussed more in this study using a qualitative descriptive approach. The research was carried out with special research procedures related to the COVID 19 protocol. Qualitative data were taken by means of observations and interviews with respondents from fish mongers in traditional markets, Mlijo traders (mobile vegetable vendors) and consumers. The results showed that traditional markets are the sources of food supply in Malang City. The distribution chain shows that Mlijo traders play a major role in distributing fishery products directly to consumers. Consumers are very dependent on Mlijo traders in terms of purchasing daily food ingredients. The cold chain system has not been implemented well in traditional markets, while the cold chain system has been not applied by Mlijo traders.
