摘要：Bioethanol is one of the alternative fuels that are considered more environmentally friendly. Bioethanol can be obtained from material that contains cellulose, such as rice straw. This study aimed to determine the optimum fermentation time to product bioethanol from rice straw hydrolysis and measured of bioethanol product from rice straw by acid hydrolysis and Saccharomyces cerevisiae fermentation. The results showed that rice straw hydrolysis by sulfuric acid catalyst produced higher reducing sugar: 21.7 g/100 g rice straw. The optimum fermentation time was 5 days which produced of 8.96% bioethanol.
