1. This study attempts to model freight transportation of specific commodity in the regional scale, particularlyto identify the shortest route of Crude Palm Oil (CPO) commodities, which are transported from factories toports using different transportation network and mode. Several activities were performed, includingidentifying the location of palm plantations and factories supporting CPO industries, identifying intermediatepoints in the road and river networks, and determining the access route of CPO transportation from factoryto the road or river networks. In determining the shortest route, various transportation networks and modesare simulated using Geographical Information System analysis by considering travel distance, time, and costas the variables influencing transportation systems. There are 113 of CPO factories identified, then beclassified into three classes by considering their production capacity. It is found that 80 factories areclassified as small (71%), 26 factories are medium (23%), and 7 factories are big (6%). The shortest route isidentified through both road and river networks. The analysis of the shortest routes shows that road networkshave shorter travel distance and time compared to the rivers. Nevertheless, river transportation offers acheaper price compared to road transportation. Therefore, there is a competition between these twotransportation modes, in which about 51% of factories probably use road networks and 49% use rivernetworks. Moreover, it is predicted that about 70% of total CPO in Central Kalimantan is transported toSampit port and only 30% is transported to Kumai port.Keywords: freight transportation, shortest route, Geographical Information System
