Valorization of Ketapang Leaves (Terminalia Catappa) as Immoblizing Agent for Hydrocarbon-Degrading Bacteria Dried Storage

Abstract One of the mitigations in dealing with problem waste oil is by using bioremediation techniques. Bioremediation techniques use biological agents that are safe for environment and more cost-effective. The method commonly developed immobilization bacteria plant fibers. fiber used ketapang leaf ( Terminalia catappa ) because it has physico-chemical properties can be bioremediation. This study aims to analyze ability T. as a living medium degrading effect storage live media waste. Five bacterial isolates this were Bacillus aquimaris, B. megaterium, pumilus, H. trueperi , R. bacterium . oil-degrading was made from powder. Tests carried out on days 0, 7, 28. results showed leaves could degrade (bio carrier) amount 19.9%-55.8%.
