Pemanfaatan Serbuk Kayu untuk Produicsi Etanol dengan Perlakuan Pendahuluan Delignifikasi Menggunakan Jamur Phanerochaete Chrysosporium
Abstract: Currently, Indonesia
is in the middle ofpetroleum crisis. One ofthe alternative fuels which can be
used as a petroleum substitute is ethanol. Ethanol can be produced from timber
waste (sawdust). Indonesia in 2003 had timber waste potency of about 3-4 millions
m3. However, ethanol production from sawdust has problems due to its lignin
content. Therefore, research on bio-delignification treatment of sawdust prior
to ethanol making process is required. In the present study ethanol was
produced by simultaneous saccharification and fermentation (SSF) using crude
cellulose from Trichoderma viride and Saccharomyces cerevisiae. The raw
materials for ethanol production are sengon (Paraserianthes falcataria (L.)
Nielsen syn.), meranti (Shorea sp.) and teak (Tectona grandis LIIVN.f.) sawdust
after pretreatment with white rot fungi Phanerochaete chrysosporium for 10, 20
and 30 days incubation time. The yield of ethanol was between 1.65-44.83 g/1.
The best combination treatment is sengon sawdust with 30 day incubation time.
