Kajian Penggunaan Surfaktan dan Sel Bebas Pada Pembuatan Bioetanol Dari Nira Nipah Kental
Abstract: The aim of the
research was to obtain the best combination treatment between early sugar
concentration and Tween80 concentration as surfactant and nutrition for
Saccaromyces cerevisiae to produce ethanol on very high gravity fermentation
from Nypa sap. The exploration research used two factor treatments with two
replications. The treatments consist of early sugar concentration N1 (20%), N2
(25%), N3 (30%) and Tween80 concentration T0 (0%), T1 (0,2%), T2 (0,4%), T3
(0,6%). Observation was conducted every 24 hours i.e sugar concentration,
ethanol concentration, amount of cell, and pH. Data obtained were analyzed by
descriptive method. The best combination treatment was T3N2 (Tween80 0,6% and N
25%) which produced ethanol 17,25%.
