Biomass waste co-firing application in coal fired power plants is one of the few promising strategy for increasing the utilization of renewable energy. In this research, the biomass supply chain systematic for power generation was studied with the aim of obtaining optimal transportation process of waste biomass to the power plant sites limited only in Java. The main analysis carried out in this research is divided into two stages, namely (1) clustering of power plants based on the distribution of waste biomass sources and (2) transportation optimization using mixed integer linear programming method with the total distance of biomass transportation as the objective function. The clustering process of this research resulted in five power plant clusters, namely (1) Paiton Cluster, (2) Wareti Cluster: Tanjung Awar-awar – Rembang – Tanjung Jati B, (3) Pacitan Cluster, (4) Padriciyu Cluster: Adipala – Karangkandri – Cirebon – Indramayu, and (5) Tuloyabu Cluster: Pelabuhan Ratu – Lontar – Suralaya – Labuan. For 5 percent biomass energy co-firing, the minimum total transport distances per day for: (1) Paiton Cluster is 97.022 km with 1.435 trucks, (2) Wareti Cluster is 82.624 km and 1.191 trucks, (3) Pacitan Cluster is 11.349 km and 108 trucks, (4) Padriciyu Cluster 136.223 km and 1.224 trucks, and (5) Tuloyabu Cluster was not fulfilled due to lack of waste biomass supply. Given the shortage of waste biomass supplies and the number of trucks operating excessively, further consideration should be done to determine the appropriate co-firing ratio percentage.
