Risk Analysis of Blackspot and Blacktail Defects in the Production Process of Frozen Vannamei Shrimp (Litopenaeus vannamei)

Vannamei shrimp (Litopenaeus vannamei) is one of the fishery commodities that has high economic value both in the domestic and global markets. The complexity of the long and multi-party frozen vannamei shrimp production process and the uncertainty of the characteristics of the raw materials make these conditions vulnerable to a risk of product quality degradation. The purpose of this research is to identify, analyze and provide risk control proposals to overcome potential hazards or sources of risk in order to minimize quality degradation that is detrimental to the company. The quality decline referred to in this study is defects in products, one of which is defects in blackspots and blacktails in frozen shrimp products. The research method used is qualitative with a quantitative approach and research data collection methods through field observations, interviews and questionnaires. Sampling was done using purposive sampling techniques. Risk measurement and evaluation analysis uses the Failure Mode and Effect Analysis (FMEA) method to determine the severity, occurrence and detection level, so that the Risk Priority Number (RPN) and Risk Value Score (RSV) values are obtained which can determine the priority of potential hazards or risk sources of blackspot and blacktail defects that must be prioritized for repair. As a result of the risk identification, there are 21 potential hazards or risk sources that cause blackspots and blacktails in products. Through the pareto diagram, it is known that there are 12 potential hazards that have RPN and RSV values that exceed critical RPN and RSV values. Through the fishbone diagram, 2 potential hazards / sources of risk are determined to be blackspot and blacktail defects which are the priority of risk management with an RPN value of 225.46 and an RSV value of 54.66 for the machine risk category on the potential danger of temperature in cold storage that is not optimal so that the minimum standard storage temperature in cold storage is not achieved. In the risk category of man or employee for potential dangers, the quantity of storage in cold storage exceeded the standard limit with an RPN value of 206.59 and an RSV value of 48.61. Risk control is carried out in a mitigated and preventive manner, at each source of risk.
