BIODEGRADATION OF PALM OIL EFFLUENT BY CONSORTIUM OF BACILLUS SP., PHANEROCHAETE CHRYSOSPORIUM AND TRICHODERMA VIRIDE

Manufacture of crude palm oil (CPO) is one of Indonesia’s industrial agro commodities that support the Indonesian economy. The increase in CPO production will increase the production of waste palm oil (Elaeis guinensis Jacq.). Palm oil mill wastewater has high potential to pollute the waters. This is due to palm oil wastewater containing high levels of COD (Chemical Oxygen Demand), and BOD (Biochemical Oxygen Demand), TSS (total suspended solid), containing solids of crude Palm oil, smelling, dark brown color, contain high levels of oils, fats and proteins as well as the rest of the cooking pressed palm fruit bunches. The purpose of this study was to determine the ability of the consortium of Trichoderma viride, Phanerochaete chrysosporium and Bacillus sp. and effective dose inoculums in degrading oil palm wastewater. This study used an experimental method to completely randomized design (CRD) factorial with two factors and three replications. Factor 1 consortium type are c1 (Bacillus sp.,Trichoderma viride), a consortium of c2 (Bacillus sp.,P hanerochaete chrysosporium) and a consortium c3 (Bacillus sp., Phanerochaete chrysosporium and Trichoderma viride) and factor 2 inoculums dose are; 0% (no inoculation), 2.5% and 5%. The results showed that the consortium of Bacillus sp., Phanerochaete chrysosporium and Trichoderma viride at a dose of inoculum 2.5% most effective in degrading wastewater palm oil, because it produces a reducing sugar levels 64.27%, lower levels of BOD by 44%, reduce levels of COD by 25.86%, reduce levels of ammonia by 60.71% and lower levels of TSS by 46.43% within 9 days.
