【 摘 要 】

Indonesia has forest plantation resources in rural areas far from the national electricity grid that have potential as feedstock for biomass based electricity generation. Although some fast growing tree plantations have been established for bioenergy, their sustainability has not been evaluated to date. This research aimed to evaluate the growth of several tree species, cultivated by rural communities in Jawa Island, for their sustainability as a source for bio-electricity. For each tree species the biomass was calculated from diameter and height measurements and an estimate made for potential electricity generation based on density of available biomass and calorific content. Species evaluated included Acacia mangium, A. auriculiformis, A. crasicarpa, Anthocephalus cadamba, Calliandra calothirsus, Eucalyptus camaldulensis, Falcataria moluccana, Gmelina arborea, Leucaena leucochephala and Sesbania grandiflora. Among these species Falcataria moluccana and Anthocephalus cadamba showed the best potential for bioenergy production, with up to 133.7 and 67.1 ton/ha biomass respectively, from which 160412 and 80481 Kwh of electricity respectively could be generated. Plantations of these species could potentially meet the estimated demand for biomass feedstock to produce bioenergy in many rural villages, suggesting that community plantations could sustainably provide much needed electricity.
