PEMBUATAN BIOETANOL DARI NIRA NIPAH SECARA SEMI SINAMBUNG (FEDBATCH) DENGAN PENAMBAHAN UREA DAN CORDYCEPS MYCELLIUM
Abstract: The purpose of this study was to obtain best combination
urea and Cordyceps mycellium on the quality of concentration ethanol. The
research was implemented to determine the optimization production of bioethanol by fermentation
method technique Very high gravity fermentation (VHGF) with free cell to see the
effect of the combination treatment in an increase in bioethanol. This research
was conducted an experiment with two factors, the first factor is Urea which
consists of four levels and the second factor isCordyceps mycellium consisting
of three levels each treatment combination obtained twelve experimental units.
Combination of Urea levels are U1 (0 g/l); U2 (0.2 g/l); U3 (0.4 g/l); U4 (0.6
g/l), while the combination of Cordyceps mycelliumlevels C1 (0 g/l); C2 (0.5
g/l); C3 (1 g/l). Observations were made every 24 hours; covering sugar,
ethanol content, the number of cells, and pH. The data were analyzed
descriptively by using a tabular or graphical. The best treatment isa
combination of U2C2 (Urea 0.2 g/l and Cordyceps mycelium0.5 g/l) that resulted
in the largest ethanol 22.5%.
