PENGARUH WAKTU FERMENTASI JERAMI PADI DALAM PEMBUATAN BIOETANOL DENGAN BANTUAN EKSTRAK KASAR ENZIM SELULASE JAMUR KANCING (Agaricus bisporus) MENGGUNAKAN METODE SIMULTANEOUS SACCHARIFICATION AND FERMENTATION (SSF)

Abstract

It has been done production of bioethanol from rice straw assisted by cellulase enzyme from button mushroom extract (Agaricus bisporus) using the Simultaneous Saccharification and Fermentation method based on the variation of fermentation time. The study aims to determine the optimum fermentation time of rice straw through bioethanol content indicators produced. Bioethanol fermented is tested qualitatively using gas chromatography. The bioethanol contents produced were determined using a UV-Vis spectrophotometer. The results showed that bioethanol content on day 1; 3 and 5 days are 0,3182%; 0,3279% and 0,4860% (v/v), respectively. The optimum fermentation time of bioethanol production in this study is 3 days with a content of 0,4860% (v/v).
