Abstract

Vannamei shrimp is one of Indonesia's leading export commodities that relies heavily on the efficiency of cold chain logistics to maintain product quality during shipping. Purpose: This study aims to analyze the factors causing distribution delays in the vannamei shrimp supply chain at a seafood exporting company in Makassar, South Sulawesi, and evaluate their impact on product quality, return rates, and export prices. Methods: The method used is the System Thinking and System Dynamics approach, by building a dynamic system model using Vensim software. Data were obtained through literature studies, interviews, field observations, and historical distribution data for 2023. Results: The results show that an average distribution delay of 12–18 hours causes an increase in temperature during transportation by 2–3°C, resulting in a decrease in shrimp quality and an increase in return rates of up to 7% of total monthly exports. Through simulations of improvement scenarios, the model shows that optimizing the criteria for export-worthy shrimp and increasing the efficiency of distribution rates can reduce the number of damaged shrimp and increase export volume. Model validation tests with a MAPE value of 5.16% indicate a good match between the simulation results and actual conditions in the field. Implications: This research is expected to be a reference for exporting companies in designing strategies to improve cold chain logistics to increase the competitiveness of Indonesian shrimp products in the international market.

Abstract

In manufacturing systems, the short shelf life of WIP (Work-in-process), categorized as a fast-moving product, can be a source of potential defects. PT XYZ is a cocoa industry located in Bandung. Manual labeling of product information in the wafer production line at PT XYZ failed to meet secure tracking and tracing requirements, resulting in increased defects due to inaccuracies in monitoring and quality control. To solve this problem, the author used the Gemba Kaizen approach as a tool companies use for continuous improvement achieved through small, low-cost steps. Our main idea is to introduce a new approach that utilizes alternative technologies by developing real-time applications to track WIP movement information in production. This barcode technology uses low-cost technology and has proven effective in helping production supervisors speed up decision-making of WIP management and minimize the risk of process failure in production that causes an increase in the number of defects. The results showed that the real-time system can reduce the number of defects from 2.6% to 1.6%. This can optimize overall inventory management and provide valuable insights for manufacturing companies looking to improve their operational efficiency through low-cost technology and real-time monitoring.
