Tingkat Pencemaran Perairan Berdasarkan Parameter Bahan Organik Dan Jumlah Bakteri Escherichia Coli Di Muara Sungai Mesjid Kota Dumai
ABSTRACT
This research was conducted in March 2020 at Mesjid River Estuary of Dumai
City, Riau Province. The aim of this research was to determine the pollution
levels in the Mesjid River Estuary based on organic matter parameters and E. coli
bacteria. DO analysis refers to SNI 06.6989.14-2004, BOD5 refers to SNI 06-
2503-2009, BOT refers to SNI 06-6989.22-2004 and E. coli bacteria refers toSNI
2897: 2008. The results of DO measurements ranged from 5.30 mg/l - 5.56 mg/l,
BOD5 ranged from 16.5 mg/l - 21.8 mg/l, BOT ranged from 15 mg/l - 162 mg/l,
and E. coli bacteria ranges from 11.1 MPN/100ml - 1,100 MPN/100ml. Based on
the results of the account of the Pollution Index, the Mesjid River Estuary waters
of Dumai City, Riau Province, are categorized as light to moderate pollution.
