Analisis Tekno-Ekonomi Produksi Gula Reduksi dari Biomassa Ampas Tebu Melalui Hidrolisis Air Subkritis

Abstract

that time and temperature have a significant effect on the yield of reducing sugar. The highest reduced sugar concentration from subcritical water hydrolysis using an oven was 27.4 g/L at 170°C operating conditions for 60 minutes with a total cost of Rp 351,744 and energy requirement of 480 W.h. In hydrolysis using an autoclave, it was obtained at 14.7 g/L at 125°C for 40 minutes with a total cost of IDR 923,079 and energy requirements of 1,936.67. Hydrolysis using an oven is more recommended than autoclaving because it is economical and has lower energy consumption.
