UJI KINERJA ALAT DESTILASI DENGAN VARIASI TEMPERATUR KOLOM UNTUK PEMURNIAN BIOETANOL BERBASIS NIRA SORGUM MANIS

Abstract

Fermentation of sweet sorghum through engineering-BioProcess batch, in a laboratory-scale has beenexamined in previous research, the concentration of the resulting bioetanol in range 9-11%. Bioetanol fermented juice ofsweet sorghum can be distilled using distillation tool. This research aims to test the performance of the tools ofdistillation. The specific purpose of this research was to determine the optimum temperature of distillation columns,against bietanol volume using the juice of sweet sorghum, determines rendemen bioetanol and determining yieldbioetanol. The research method through 3 (three) stages is the production stage of sorghum sauce obtained from thepressed sweet sorghum staple, the fermentation stage of sweet sorghum juice 16 Brix using batch biochemicalengineering system, and purification stage of bioethanol carried out on the distillation device built in this research . Theresult of the research shows that the temperature of 87OC column can produce 13% bioethanol by 1368 ml forfermentation process of engine batch system, with yield of 5.9% and yield of 9.8%.
