Kali Otik is one of the tributaries in Lamongan which is often referred to as Kali Otik or Kali Kitchen which is indicated to be polluted. Efforts are being made to overcome the water problem by conducting bioremediation. Bioremediation is meant by using a consortium of microbes in the hope that the waste in the waters can decrease and water quality will increase. The general objective of this study was to evaluate the potential of the microbial consortium to decrease levels of LAS and other organic pollutant parameters (BOD, temperature, pH) and increase DO. The method used in this study is qualitative with a real experimental model. By making a consortium by utilizing the microbes found in organic EM4. The object being studied is that there are two points with each point being sampled on the surface and depth. The results obtained from this study showed that the microbial consortium can reduce LAS levels and improve water quality. LAS levels on water surface can be decreased 0,28%and 0,4% on the depth. DO levels on water surface can be increased 4,1%and 3,8% on the depth. BOD levels on water surface can be decreased 0,89%and 1% on the depth.
