Benthic Macroinvertebrates Diversity as Bioindicator of Water Quality of Some Rivers in East Kalimantan, Indonesia

الملخص EN

The objectives of this study were to clarify and evaluate the water quality of a number of rivers in East Kalimantan province of Indonesia.

For this purpose, our study successfully utilized the benthic macroinvertebrates diversity as well as physical-chemical parameters of river’s water.

For instance, based on the values of Average Score per Taxon (ASPT) and the National Sanitation Foundation-Water Quality Index (NSF-WQI), Karang Mumus River was categorized as polluted with Chironomus sp.

and Melanoides tuberculata as codominant taxa.

In addition, Jembayan River exhibited doubtful or moderate quality containing M.

tuberculata and A.

parvula as codominant taxa.

However, Pampang River was found to be the cleanest river with Odonata and Baetidae families as codominant taxa.
