Kualitas Perairan Kanal Sungai Jawi dan Sungai Raya Dalam Kota Pontianak Ditinjau dari Struktur Komunitas Mikroalga Perifitik
Abstract: Sungai Jawi and
Sungai Raya Dalam canals were frequently
benefited by communities for a variety of daily necessities. These activities
led to changes in water conditions and disrupt community structure in it. The purpose of
this study was to determine
the periphytic micro-algae
community structure and
the level of water pollution in Sungai Jawi and Sungai Raya Dalam canals. The samples
were collected in
Sungai Jawi and Sungai Raya Dalam canals. The determination
of stations was based on
environmental setting. Each canal
was divided into
4 stations with
3 points laying
substrate. The results
showed that the
periphytic micro-algae were from
3 divisions and 3 classes, namely
Chrysophyta
(Bacillariophyceae), Chlorophyta (Chlorophyceae), and
Cyanophyta (Cyanophyceae). There
were 26 genera
of periphytic micro-algae
in Sungai Jawi Canal and 25 genera of periphytic micro-algae in Sungai
Raya Dalam Canal. Total abundance of periphytic micro-algae in Sungai
Jawi Canal was 378,15 -
651,86 ind/cm2and in Sungai Raya Dalam was 488,50
- 657,13 ind/cm2.
The highest abundance
was found in
the both canal
from the Bacillariophyceae class,
Navicula genus. Shannon-Winner diversity index on Sungai Jawi and Sungai Raya Dalam canals
was classified as middle category
(2,0393 - 2,5690). Pollution level that occurred
on both canal was still relatively mild.
