Citarum river is categorized as heavily polluted river. The result of water quality monitoring from the West Java Regional Environmental Management Agency (BPLHD) in 2015 showed that the upstream section of the Citarum River was categorized as heavily polluted. This study aims to determine the effectiveness of absorption of heavy metals and bacteriology with various absorbent composition of quartz sand/andisol soil/zeolite/activated carbon in the Citarum River, West Java. The method used was the refining silica process and making a variety of compositions of quartz sand, andisol soil, zeolite and activated carbon. The results showed that the variation of the absorbent quartz sand/andisol soil/Zeolite/activated carbon had met the parameters of Permenkes 32 of 2017 in handling metals and E. Coli, while other parameters had not. The quartz sand/andisol soil/zeolite/activated carbon with a composition of 20/20/20/40 is the best composition in handling Pb and Cu metals. The optimum composition of the Quartz Sand/Andisol Soil/Zeolite/Activated Carbon adsorbents when total coliform descent at the location before the dam, Walahar Dam, Citarum 1 River and Citarum 2 RIver, respectively are 25/25/25/25, 20/40/20/20, 0/100/0/0, and 20/20/40/20. The optimum composition before the Dam and Walahar Dam adjustment occurred in the composition F, G, H, I and J while for the locations of the Citarum 1 River and Citarum 2 River, the optimum composition was in the treatment composition D, E, F, G, H, I and J. The complete results can be seen in table 7 as follows. The results of statistical analysis showed that variations in the composition of the adsorbent did not affect the decrease in Total Coliform. The results of statistical analysis showed that variations in the composition of the adsorbent affected the decrease in Cu and Pb metals, as well as E. Coli.
