Most waste cooking oil (WCO) in Semarang is still disposed of in landfills since there is an inadequate facility to collect those wastes. There are only three collection centers of WCO identified in Semarang. The alternative to sell WCO is also not the best option as the amount of WCO generated from households is less than the culinary enterprise. Thus, having a collection channel that can thoroughly cover all the supply points of WCO from the household in Semarang is a necessity. This research will design a collection channel to provide facilities so the waste can be appropriately managed. The analysis determines the number, location and capacity of each collection center, standard operating procedure of WCO collection, and the picking route. The number, location, and breadth of the collection center are determined using Maximal Covering Location Problem. The finding shows that to facilitate all the potential supply of WCO in scenario 1 with a range of 2 km mileage need 95 collection center. In contrast, in scenario 2, a distance of 1 km requires a collection center of 146 points. Previously, this study began by identifying community behavior towards waste cooking oil by surveying 347 households.
