摘要：The bioremediation technique for a contaminated liquid waste of heavy metals using indigen ous bacteria is a convenient alternative to steps continues to be developed. The research aims to find out the effectiveness of an indigenous bacterial consortium in bioremediation of contaminated liquid waste by cadmium by ex-situ. Experiments were arranged in RAL made in ex-situ where a liquid waste industry was given five treatments, namely control and four indigen ous bacterial consortia (A, D, E, and J) obtained from the isolation of bacteria originating from cadmium-contaminated of waste in Pasuruan district . Furthermore conducted observations of BOD5, COD, d.o. and Cd for seven days to find out the effectiveness of bioremediation. The results showed the four indigenous bacteria consortia have the bioremediation ability to reduce levels of cadmium, BOD5, COD, and increasing levels of DO. Indigen ous bacterial consortia D has the best ability of liquid industrial waste bioremediation by ex-situ. Indigen ous bacteria l consortia J has the best of capacity reduction levels of cadmium, then the other of indigen ous bacteria l consortia.
