influenced pollution. The contamination may disrupt the ecological balance of aquatic
organisms. Therefore, the aims of this research studies to determine the water quality of
Pelawi River in Pelawi Village based on physics, chemical and biology parameters. The
research was conducted in April to June 2014 in the waters of Pelawi River in Langkat
Regency of North Sumatera. Physics and chemical parameters were analyzed by the
Storet method based on water quality standard required by Government Act
No.82/2001, while biological parameters (macrozoobenthos) were analyzed by
Abudance and Biomass Comparison (ABC) curve. The location of sampling sites was
done by Purposive Random Sampling method in three core areas are station 1
(agriculture activity), station 2 (domestic activity) and station 3 (industry activity). The
results shows based on physical, chemical and Biology parameters of water, the water
quality of Pelawi River were classified slightly polluted until moderatelly polluted
