Feasibility Study on the Production of Bioethanol from Tapioca Solid Waste to Meet the National Demand of Biofuel

This study aims to assess the potential ethanol produced by employing tapioca solid waste to support energy demand in Indonesia. A bioethanol process was simulated under bioactivity process using Saccharomyces cerevisiae . Reduced sugar and polysaccharide were used as essential substrate. The simulation result indicate that SSF requires (59 to 62) h and overall process takes approximately seven days. Having averagely 564 414.7 t • yr –1 of tapioca solid waste, it is possible to produce 57.793 . 10 3 kL • yr –1 . This number could contribute to the 1.89% and 33.41% of bioethanol demand according to Ministry of Research and Technology and Ministry of Energy and Mineral Resource, respectively.
