A System Dynamics Model of Frozen Fish Supply Chain

The system dynamics methodology examines the intricate behaviors of complex systems through time, incorporating inventories, transfers, feedback cycles, lookup functions, and temporal delays. In fisheries systems, the interaction between resources and management entities is intricate, with the dynamics of fisheries significantly influencing the formulation of effective policies. Fisheries hold a vital position in Indonesia's economy, contributing to food security, nutrition, and the welfare of fishermen. Under Law Number 7 of 2016, the fisheries sector covers all activities, from resource management to the marketing of marine products. With its rich fishery resources, Indramayu Regency is a major contributor to West Java's fish production. TPI Karangsong, the hub of fishing activities in Indramayu, is a key player in the frozen fish supply chain, relying heavily on cold storage facilities to ensure product quality. Consequently, the system dynamics approach proves valuable in understanding the frozen fish supply chain by modeling the interactions between different variables and evaluating the impact of policies to improve fish quality. The system dynamics model in this study consists of six sub-models: fish at TPI, cold storage, refrigerated cabinets, total revenue, cash, and cold trucks. The simulation results provide policy recommendations to improve the quality of frozen fish at TPI Karangsong, namely the baseline scenario, cold truck scenario, cold truck scenario, truck and cold storage integration scenario, cold storage and fish catch drop integration scenario.
