affecting water quality in Belawan River Pancur Batu subdistrict. This study aims
to determine the water quality based on physical and chemical parameters as a
result of community activities in Belawan River Pancur Belawan Subdistrict of
Deli Serdang Regency. Physical and chemical parameters of water were analyzed
with method Storet. The study was conducted in March and April 2015. The

(Control), station II (dredging sand), and the station III (Recreation and MCK).
The value of physical and chemical parameters of water include temperature from
25.00 to 27.00 ° C, turbidity (TSS) from 22.68 to 28.86 mg / l, TDS 156.6 to
187.2 mg / l, DO 4.80 - 6.00 mg / l, pH 7.20 to 8.10, BOD 1.20 to 2.20 mg / l,
nitrate 0.812 to 1.123 mg / l, phosphate from 0.112 to 0.153 mg / l, the organic
content of the substrate from 0.372 to 0.705 %. Based on the physical and
chemical parameters of water, the station I and II meet the water quality standard
Class II (lightly polluted), whereas the third station meet Class II water quality
