Cikeruh River is one of the tributaries of the Citarum River which has received a variety of inputs, which can affect the river water quality and cause pollution. Macrozoobenthos is an organism that can determine the pollution of waters. This research aims to determine the spatial distribution of macrozoobenthos communities in the Cikeruh River as the indicator of pollution. This research was conducted in July 2019 - August 2019 using the field survey method. The data collection technique used is purposive sampling, setting 5 stations based on environmental factors and land use around the river flow. The parameters observed were the physical-chemical parameters of the waters, physical-chemical parameters of the substrate and macrozoobenthos as biological parameters as indicators of pollution, as well as calculating the abundance of macrozoobenthos, diversity index, uniformity index, species deficit and morisita index. The results of the macrozoobenthos spatial distribution along the Cikeruh River flow differed at each location of observation. At station 1 found several intolerant species Heptagenia sp., Tipula sp., Leptophelbia sp., Polycentrophus sp. and Enallagma sp., station 2 found several facultative species Melanoides tuberculata, Lymnaea sp., Tarebia granifera, Sulcospira testudinaria, and Corbicula fluminea,, station 3 found several facultative species Melanoides tuberculata, Lymnaea sp., Tarebia granifera, Sulcospira testudinaria, Pomacea canalicuta and Corbicula fluminea, station 4 found several facultative species Melanoides tuberculata, Tarebia granifera, Sulcospira testudinaria and Corbicula fluminea, and station 5 found intolerant species Chironomus sp., Tubifex sp., and Lumbriculus sp. The abundance of macrozoobenthos is around 590 ind/m2 - 7420 ind/m2. Diversity index ranges from 0.46-1.85. The uniformity index ranges from 0.16 to 0.64. Species deficits at each station are different. Cikeruh River morisita index ranging from 0.14 to 0.80 which is in the uniform category.
