This research aims to conduct the zoning designated policy to find the appropriate number of oil palm collector (called ramp ), which is the main player to collect and distribute the fresh fruit bunch in upstream of oil palm supply chain. The set covering problem is applied together with the consideration on the distance between ramps. In this paper, the distance on 3 kilometres is implemented on set covering model and it is solved by the premium solver platform in Microsoft Excel. As a result, it showed that the number of appropriate ramps is at 110 ramps, instead of 452 ramps found in present.
