HUBUNGAN ANTARA KADAR GULA REDUKSI, JUMLAH SEL MIKROB DAN ETANOL DALAM PRODUKSI BIOETANOL DARI FERMENTASI AIR KELAPA DENGAN PENAMBAHAN UREA
Abstract: This research was
conducted to determine the best concentration of urea in bioethanol
fermentation from coconut water using Saccharomyces cerevisiae in increasing
ethanol production. This research was done experimentally using four treatments
and two replications. The combination of urea levels were U1 (without urea), U2
(0,2 g/l), U3 (0,4 g/l) and U4 (0,6 g/l). Observations were made every 24 hours
for 3 days include ethanol production, sugar reduction and the number of cells
microbes. Data obtained from the analysis descriptively using tabulation and
graphs. The best treatment was found in U3 (urea 0,4 g/l) with the highest
ethanol’s yield of 11,25%, reduction of residual sugar amount of 168,13 g/l and
the number of cells/mL of 1,0x109 in the three day.
