ABSTRACT
River is a water ecosystem with quality that can be influenced by various anthropogenic factors. Therefore, these activities cause changes in river water quality (Cha et al, 2009). Proper, fast and relatively inexpensive water quality assessment as a basis for river management is very necessary. This study aims to prove the type and abundance of macrozoobenthos are affected by the physical-chemical condition of the habitat so that it can be used as a bioindicator in assessing river water quality with a case study in the Upstream of Citarum River. The method used in this study consists of two stages, namely determining the status of river quality with Pollution Index and determining the components to see the relationship of water quality parameters to the abundance of macrozoobenthos with Principal Component Analysis (PCA). Based on these studies, the results were that at the location of the study status of the river quality consists of slightly polluted and mild polluted. For slightly polluted status there was Corbicula sp. as the dominant macrozoobenthos parameter with the parameters of Dissolved Oxygen, Organic Carbon and N-O in clay-dominated sediments. Whereas for river areas with mild pollution, Enallagma sp., Tubifex sp., and Chironomous sp. as a bioindicator of mildly polluted water quality and it has a relationship with the parameters of Nitrate, TSS, and P-Total.
