    Abstract

    Waste pulp industrie was contained of many of COD and BOD and it was contained of lignin from ow IDItcm become main reason. That waste pulp rused has some process that it's separated by 2 step, it's chemical and biology, tbas us for pushing operational cost (or that waste ruse. Lignin degradation in this biology operation used actif mud that 1ISUIIly to reduce COD and BOD about 30-h. The research of COD and BOD reduction usecJto reduce lignin with Tremetcs Vcnicola sp help for obtained the level reduction in higher value and also to reduce operational cost of waste ruse. The purpose in this research is (or to know how the ability ofTremetes Versicolor sp to reduse the lignin and 10 m.tuc COD and BOD disposal from waste pulp industrie. The benefit that wish to appear from this research is to call GIl wast. industrie with low COD and BOD disposal and hope to bring another alternative to reduce COD and BOD disposal in .. pulp industrie. The mechanism from this, research is the waste pulp industrie that has lignin rused by used Tremetes Versicolor mushroom, and then it was incubUted (aeration) since 6-14 dayswith to variat the mushroom quantity about 10=30 paD pc 250 mlliquid waste. Incubation operational worked in pH acid level is. .From the research output was obtained the biggest reduce for COD and BOD disposal from wlb"te pulp industric i 7PIe for COD and 71% for BOD, used mushroom about 30 gram and incubate time since 14 days .
