HUBUNGAN ANTARA KADAR ETANOL, KADAR GULA REDUKSI DAN JUMLAH SEL DALAM PRODUKSI BIOETANOL DARI AIR KELAPA KENTALDENGAN PENAMBAHAN TWEEN80TM

Abstract

This study was conducted to determine the best concentration of Tween80™  in the manufacture of bioethanol from coconut water condensed by Saccharomyces cerevisiae. This study withincreasingthe urea and Tween80™ varying concentrations of this study conducted an experiment with four treatments and measurement in duplicate. Concentration of Tween80 ™ were T10 (0%), T2 (0.1%), T3 (0.2%) and T4 (0.3%). Observations were made every 24 hours; including ethanol content, sugar content and the number of cells. Data were analyzed descriptively by using a tabulation and graphs. The best treatment was a combination of T2 (urea 0.4 g / l and 0.1% Tween80™), which produced the largest ethanol 12%.
