Abstract
Two different process configurations, simultaneous saccharification and fermentation (SSF) and separate hydrolysis and fermentation (SHF), were compared for ethanol production from solid waste of tapioca (onggok). Optimization modeling using Response Surface Methodology (RSM) for glucoamylase and ammonium sulfate concentration in both of SSF and SHF were carried out to obtain optimal concentration of ethanol production. The optimum condition was achieved using 0.025 % v/v of glucoamylase and 0.096% w/ v of ammonium sulfate for SHF. In contrast, the optimum condition for SSF was 0.020 % v/ v of glucoamylase and 0.155% w/v of ammonium sulfate. The model predicted SHF processing to be super ior. The superiority of SHF over SSF was confirmed experimentally, the result showed ethanol yield of SHF was 17.817 g/L and ethanol yield of SSF was 9.52 g/L. A high similarity was observed between the predicted and experimental results, demonstrating the accuracy of the model
