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