PEMBUATAN BIOETANOL MELALUI FERMENTASI NIRA TEBU (Saccharum officinarum) MENGGUNAKAN Saccharomyces cerevisiae DENGAN PENAMBAHAN VITAMIN B KOMPLEKS SEBAGAI NUTRISI FERMENTASI
Abstrak: Bioethanol is
alternative energy produced from the fermentation of carbohydrates like sugar
cane juice. The fermentation process is influenced by several factors like
nutrition of fermentation. This research to determine the addition weigh (g) of
vitamin B complex gr and time of fermentation as theoptimumconditions of
fermentaced toproduceethanol with high concentrations. Sugar cane juice as raw
material fermented using Saccharomyces cereviceaea with variation additional of
vitamin B complex are 0%; 0.1%; 0.2%; and 0.3% (w/v) sugar cane juice fermented
during time of fermentation with the variation are 6 day, 7 day and 8 day.
Purification of bioethanol by process of distillation.Alcohol content analysis
using gas chromatography. The results showed optimumconditions of fermentaced
are addition of Vitamin B complex is 0.1% (w/v) and time of fermentation is 7
days to produced ethanol 30.177%.
