【 摘 要 】

Many countries are currently making efforts to obtain alternative energy to reduce dependence on fossil energy resources. “Uwi” plant is a carbohydrate source that has many types and is tolerant of being planted on the upland, so it has the potential to be used as a food crop and as bioenergy. This research aims to study the potential of varieties of “uwi” (Dioscorea sp.) as raw material for ethanol production. The eight varieties of “uwi” were studied to assess their ethanol potential. The selected raw materials are Dioscorea alata L. (white yam, purple yam, and yellow yam); Dioscorea esculenta (Lour.) Burkill (“uwi gembili” and “uwi gembolo"); Dioscorea bulbifera L. ("uwi gandul"); Dioscorea pentaphylla L. ("uwi katak") and Dioscorea hispida Dennst. (“uwi gadung"). A field experiment with Randomized Block Design was used to obtain homogenous tuber raw material, followed by laboratory methods on the assessment of ethanol production potential through fermentation. The research showed that the variety, D. hispida had the highest ethanol content (4.94 %), followed by D. esculenta (4.16 %) and D. alata (white yam) (3.89 %). The lowest ethanol production was obtained from D. pentaphylla (0.36 %) and D. bulbifera (1.53 %). However, in terms of productivity, D. alata (white-yam) is the most prospective considering its high production, ease of cultivation and tolerance of forest stands.
