Indonesia is an archipelago nation since statistic shows that Indonesia consists of more than 13,000 islands, it is natural for inter-insular ships to play a dominant role in connecting one island to another supported by other local ships. In comparison, the inter-insular ships docking and unloading in Surabaya’s port, as well as the Ship’s call and DWT Ship’s call, outweighs the local ships.

On the other hand, in the same period of time, local ships only unloaded 1,204 units of 158,877 tons; 901 units of 157,663 tons; 1,023 units of 126,111 tons, 1,124 units of 403,826 tons; 919 units of 176,550 tons. This research wants to analyze the number of inter-insular ships, based on several internal and external variables: Unit Ship’s Call (X1), DWT Ship’s Call (X2), Inflation (X3), and Unloading Cost (X4).
