Dock Optimization Planning Gresik Port In 2026-2030

Gresik public port plays the role of a seaport in economic growth, especially to facilitate trade, sources of foreign exchange earnings, importing consumer and capital goods, exporting goods, providing employment opportunities, and so on. The purpose of this research is to forecast the flow of goods through conventional ocean docks and the archipelago in 2026-2030. For this reason, in solving the above problems, a queuing model is used with a distributed ship arrival time testing the Poisson data distribution pattern and an exponentially distributed ship service time with unlimited queues/sources and many services in accordance with testing using the Kolmogorov-Smirnov Gooness of Fit Test. The economic marginal cost of adding one pier unit is IDR 820,199 million, while the total cost for each optimal pier composition per year is always below IDR 820,199 million, and the addition of one unit of the archipelago pier is unlikely to reduce waiting cost at the port. In addition, the addition of the pier is not needed during the years 2026-2030, because the total minimum cost is always smaller than the cost of adding one unit of the pier. For this reason, applying the results of this study, the state will avoid a waste of IDR 820,199 million during 2026-2030.
