Leachate is a liquid that occurs as a result of mixing rainwater runoff with rubbish that has decayed and contains very fine suspended substances and pathogenic microbes. Leachate can cause potential contamination for both surface and groundwater. In this study biodegradation of leachate by microorganisms was carried out to reduce the content of organic and harmful inorganic substances. The purpose of this study was to evaluate the potential biodegradation of bacterial isolates isolated from landfill leachate. The method used in this study is an experimental method with three repetitions. The parameters observed included the levels of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) and ammonia, for 14 days the biodegradation process. Data from the research results were analyzed using Variety Analysis (ANOVA) followed by Duncan's multiple distance test. The results showed that a consortium of Bacillus subtilis, Bacillus licheniformis, Bacillus pumilus, Pseudomonas putida, Nitrobacter and Nitrosomonas (K3) capable of reducing BOD levels by 68%, reducing COD levels by 89%, TSS by 71%, and Ammonia by 92 %, reducing 90 % of chrome and 90 % of lead.
