Energy is needed by people but sooner or later the world's oil reserves will be depleted. Generally energy needs are dominated by fossil fuels such as petroleum, natural gas and coal. It is time for Indonesia to reduce dependence on fossil fuels by developing alternative fuels that are renewable and environmentally friendly (renewable). There are three types of alternative energy that can be researched and developed in the world today such as biodiesel, bioethanol and biogas. One potential alternative to be developed was the use of bioethanol. Bioethanol is an alternative fuel that is processed from plants (biomass) by fermentation. In this study, the raw material used to make bioethanol is jackfruit seeds. During this time only used as a jackfruit seeds that only a small proportion of waste utilized as livestock feed and even largely discarded. In fact, if further processed jackfruit seeds can provide added value. This research aims to make bioethanol with various concentrations of yeast and fermentation time. The main process is hydrolysis fermentation using yeast Saccharomyces Cereviciae; and purification by distillation. The variables used were changes in the concentration of yeast 3, 6, 9%; and fermentation time 2, 3, 4 days. From the analysis of the research results obtained bioethanol yield per amount of raw materials best start was 10.9 ml/kg with a density of 0.959 g/ml and the calorific value sebasar 196.899 kkal/kg, ie at 9% concentration variation yeast and fermentation time 3 days. 130425007
