KOMUNITAS MAKROZOOBENTOS DAN AKUMULASI KROMIUM DI SUNGAI CIMANUK LAMA, JAWA BARAT
ABSTRACT: The residue of human
activities and batik industrial waste water surrounding the river will be able
to increase the accumulation of chromium and to disrupt macrozoobenthic
communities in the river. The aims of this study was to assess the impact of
human activities surrounding the river to the macrozoobenthic communities and
the accumulation of chromium in Cimanuk Lama River, Indramayu District, West
Java. The study has been conducted from AprilMay 2015
based on three times sampling at three different sampling stations. The result
of this study shows that the chromium accumulated in the waters of all station
still meet the standard quality ranging from 0,010-0,016 mg/l, but only
station 1 fulfills the standard quality for chromium accumulated in the river
sediment with the range of all stations was about 11,72-46,63 mg/kg. The
results also show that the community index analysis describes the change of
macrozoobenthic community at all stations caused by environmental pressure,
especially at the station 2 which is indicated by the highest score of Family
Biotic Index. The accumulation of the chromium in the waters and the change of
macrozoobenthic community structure are mostly influenced by the use of the
Cimanuk Lama river long for agricultural and fisheries activities, and also
batik home industry.
