Abstract

This research was conducted to determine the water quality of Situ Ciburuy based on the structure of the macrozoobenthos community as a bioindicator. The research was conducted using a survey method and purposive sampling method. Observational data were analyzed descriptively. The results showed that the level of water quality in the Situ Ciburuy based on macrozoobenthic bioindicators was lightly polluted. This is indicated by the low to moderate diversity of macrozoobenthos, which ranges from 1,3 to 2,1. Macrozoobenthos uniformity in situ Ciburuy which is found at each station is categorized as moderate population in unstable conditions because the uniformity index ranges from 0.51 to 0.66 which indicates low uniformity of macrozoobenthos in situ Ciburuy. Based on the FBI value, Situ Ciburuy has slightly bad to very good water criteria, station 1 has an FBI value of 6,1 with slightly bad water criteria, the value of FBI station 2 is 4.8 with good water criteria, the value of FBI station 3 is 4.0, station 4 is 3.8 and station 5 is 3.9 with very good water criteria.
