Abstract


Energy availability is an absolute requirement in national development efforts at present or in the future, because it can guarantee energy needs which are the main challenges for the Indonesian state. The existence of limited energy sources, while the need continues to increase requires alternative sources of fossil energy. Bioethanol is one of the bioenergy which is an alternative to replace the use of fossil fuels. This study aims to obtain bioethanol from bagasse (bagasse). The method used is hydrolysis with sulfuric acid. The research step begins with pretreatment of bagasse raw materials, grinded to a size of 100 mesh. Furthermore, the hydrolysis with sulfuric acid at a temperature of 150 oC for 1 hour, to form a slurry. The fermentation process uses a mass variation of yeast Saccharomyces cereviceae with a variation of 6.75; 8.75; 11.25; 13.75 and 16.25 g, for 4 days with pH 5, room temperature and anaerobically. Purification is done by distillation method . The best yield in the study with a mass variation of yeast saccaromyces cerevisiae with a pH of 5 and a fermentation time of 4 days was 57.6 mL. The bioethanol content obtained was 98.93 percent.
