Potential of Biomass as Bioenergy Feedstock in Indonesia

抄録

As tropical country, Indonesia is rich with potential biomass that can be utilized as bioenergy feedstock. Crude palm oil (CPO) is currently the main feedstock used to commercially produce biodiesel in Indonesia. In addition to CPO, various agricultural crops can be utilized as bioenergy feedstocks, such as coconut, jatropha, sugarcane, sago, etc. In order to determine the type of plant potential after oil palm as bioenergy feedstock in Indonesia, an analytical hierarchy process (AHP) was conducted based on seven criteria including 1) food crop with surplus production, 2) plant productivity, 3) yield of biofuel, 4) multipurpose energy plant, 5) plant development readiness, 6) government policy, and 7) uncompetitive land use for food crop/easiness to grow in marginal land. Results of AHP analysis showed that palm oil was the most potential plant for biodiesel feedstock (0.237) followed by coconut (0.179), reutealis (0.147), calophyllum (0.120), pongamia (0.119), jatropha (0.100), and rubber (0.095). It was also shown that sugarcane (0.222) was the most potential feedstock to produce ethanol, followed by sorghum (0.174), sago (0.167), sugar palm (0.152), maize (0.143), and cassava (0.141).
