Crude palm oil (CPO) is one of Indonesia’s leading commodities. The palm tree is generally planted in Borneo and Sumatera areas, and the raw palm oil is shipped to Java for the next production. The sample was taken from the CPO discharging data at Port of PT X, Gresik-Indonesia. CPO shipping generally uses a tug and barge, tanker, or SPOB. Still, these conditions are not considered optimal because the ship returns empty (imbalanced cargo) and has a long idle time during the unloading process. Port workers must generally mix and manually clean solid oil at the barge/tanker hold during the discharge process. With a comparative method, this study used an articulated tug and barge system compared with existing transport modes in their investment and profit calculations. The ATB is more efficient by maximizing sea time and reducing the port time. So that the tug that generally waited for the barge to be dismantled could return to the loading port, bringing another completed barge. This application will optimize the productivity of the ship, as the tugboat does not stop operating.
