The potential of sweet sorghum in Indonesia as a raw material for bioethanol production is very large. Sweet sorghum is a plant not a food crop. Sweet sorghum juice is a liquid containing sugar can be produced by extracting or pressing sorghum stems. The sugar content of sweet sorghum juice varies depending on the type, one of which is genotype 4-183 A. The purpose of this research is to optimize the conditions of inoculum and substrate using a batch system. The parameters to be analyzed are the percentage of bioethanol yield, total biomass or yeast cells and total sugar content. This research shows that the process of fermentation-batch of juice sweet sorghum of genotype 4-183A with 9% optimum inoculum concentration and 16% optimum glucose concentration can produce high concentrations of biethanol.
