Abstract

The goals of this research was to identify Phosphate and Nitrate contents and also macrozoobenthos density in Belawan River. Activities done by the community such as industries, PLTU, PDAM and aquaculture are found in Belawan River area. This action produce waste straightly discharged into water river, emerging several bad effect on water quality such as Phosphate, Nitrate, and Macrozoobenthos density. Retrieval of data with Purposive Random Samplin with five analysis the location. The method used in this research was included in the measurement of density (K), KR (relative density), and FR (frequency of attendance) of Macrozoobenthos. Identification of Macrozoobenthos results obtained in the Belawan river was amounted as nine genera. The lowest Macrozoobenthos density was at the Station 5 (Scylla), Station 4 (Hirudo), Station 2 (Microbachiumand Melanoides) and Station 1 (Melanoides) with a density of 3.703, and the highest was instation 4 (Polymesodaerosa) with a density of 629.62. Based on phosphate concentrations, it is included as hypertrophic (0.14-0.18 mg/l,). Based on nitrate concentration, it is included as eutrophicand mesotrophic waters (1.18-7.57 mg/l)
