KARAKTERISTIK BIOINDIKATOR CISADANE : KAJIAN PEMANFAATAN MAKROBENTIK UNTUK MENILAI KUALITAS SUNGAI CISADANE

Abstract

The biomonitoring conducted to evaluate the condition of water bodies in aquatic ecosystems by utilizing bioindicators as a starting measuring. Bio-indicator that is often used is macroinvertebrates that live settle in the riverbed which can indicate environmental quality characteristics of water bodies where they live. Cisadane river quality monitoring by utilizing bio-indicators of macroinvertebrates was carried out in 2003 to 2007. 2010 and 2013 at some point representing the upstream segment (C01-Muara Jaya), middle (C05-Karya Bhakti; C06-Jasmin) and downstream (C22-Kali Baru ). The approach used diversity index (Diversity Indices) and the biological index (Biotic Indices).Based on the charakteristics of macroinvertebrate, state of Cisadane river water quality from upstream to downstream macroinvertebrate are in moderate to poor condition. This status is obtained by combining the results of the calculation H ‘, per cent (\%) EPT and ASPT. As well as supporting data as the results of the analysis of chemical parameters DO, BOD, COD, NO3 and TSS. Cisadane upstream areas are characterized by the Order Ephemeroptera, Familia Lepthophlebidae, Paraleptoplebia Genus, Species P. submarginata and P. cinca. Cisadane central area which dominant domestic waste is characterized by the Order Ephemeroptera, Familia Baetidae, Baetis genus, species B. Niger and the Order Trichoptera, Familia Hydropsychidae, Hydropsyche Genus, Species H. siltalai and H. anguistipennis. While the downstream region Cisadane characterized by Class Oligochaeta, Familia Haplotaxidae and worms Tubifisidae.
