FERMENTASI BIOETANOL DARI NIRA NIPAH KENTAL SECARA SEMI SINAMBUNG DENGAN PENAMBAHAN ERGOSTEROL
Abstract: The aim of the
research was to obtain the best combination treatment between ergosterol
concentration and sugar concentration 250 g/l; Tween80 0,2%. Tween80 and
ergosterol as surfactant and nutrition for Saccaromyces cerevisiae to produce
ethanol on very high gravity fed batch fermentation from Nypa sap. The
exploration research used four treatments with duplicate measurements. Treatments
consist of E0 (ergosterol 0 mg/l), E1 (ergosterol 18 mg/l), E2 (ergosterol 24
mg/l) and E3 (ergosterol 30 mg/l). Observation was conducted every 24 hours to
sugar concentration, ethanol concentration, amount of cell, and pH. The best
combination treatment was E1 (Tween80 0.2%; sugar 250 g/l and ergosterol 18
mg/l) which produced ethanol 17,57%.
