Konsentrasi Bakteri Indikator Pencemaran Perairan Di Teluk Sirih Padang Sumatera Barat
ABSTRACT
This research was conducted in October 2019 in the waters of Sirih Bay
Padang, West Sumatra Province. The objective of this research aims was to
determine the number of bacterial cells as indicator of water pollution (E. coli) in
the waters of Sirih Bay, Padang. The method used in this study was a survey
method. Polluted waters in Sirih Bay as sampling location was divided into 3
stations, namely the PLTU area (St. I), near BPBALP Padang (St. II) and a
residential area (St. III). Isolation of fecal coliform (E. coli) bacteria was carried
out by assumption and affirmation tests which were further identified and carried
out physiological and biochemical properties. The results showed the total number
of coliforms in Sirih Bay waters in the assertion test using BGLB media ranged
from 75-460 MPN/ml. This indicates the existence of pollution of coliform
bacteria in these waters based on the Decree of the State Minister of Environment
No. 51 of 2004 concerning Sea Water Quality Standards, the maximum level of
total coliform bacteria is 1000 MPN/100 ml. The results of this study indicated
that the waters of Sirih Bay are considered to be in poor waters.
