Water pollution level of the Upstream Citarum river based on macrozoobenthic family biotic index

Abstract

Citarum River was known as the dirtiest river in the world in 2009, it was caused by the increase in population growth around the Citarum River, which damaging the river and the surrounding environment. This research was conducted at 4 stations, namely 1.Situ Cisanti; 2.Wangisagara; 3.Majalaya; and 4.Sapan, by using purposive sampling method and descriptive quantitative analysis method to determine the level of water pollution in the Upstream Citarum River based on the family biotic index of macrozoobenthos. The results showed that the level of water pollution in the Upstream Citarum River was light to severe. The FBI value of the Upstream Citarum River ranges from 3,95-5,85. Station 1 and station 2 have slightly bad water criteria with each FBI value is 5,85 and 5,77, station 3 has an FBI value of 3,95 with very good water criteria, and station 4 has an FBI value of 5,63 with sufficient water criteria.
