| Summary: | Currently, Indonesia is in the middle ofpetroleum crisis. One of the alternativefuels which can be used as a
petroleum substitute is ethanol. Ethanol can be producedfrom 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 (fectona grandis LINNf) sawdust after pretreatment with white rot fungi Phanerochaete
chrysosporiumfor J 0, 20 and 30 days incubation time. The yield of ethanol was between J.65-44.83 gll. The
best combination treatment is sengon sawdust with 30 day incubation time. |
