Abstract

Changes in water conditions greatly affect the presence and ability of aquatic biota to survive in their habitat. The presence of these biota are largely determined by the physical and chemical conditions of water, so that the community structure of aquatic biota will vary according to the conditions of physical and chemical parameters of water. It allows aquatic biota to serve as bioindicator of water quality changes. The study aims to determine the abundance and diversity of phytoplankton, zooplankton and benthos in Ranu Pani and Ranu Regulo, to know the physical and chemical properties of water and to obtain bioindicator of the phytoplankton, zooplankton and benthos in order to assess water quality in both Ranu. Research using quantitative descriptive method to describe about the diversity index and abundance of phytoplankton, zooplankton and benthos related to water quality in Ranu Pani and Ranu Regulo. Samples were taken at 7:00 until 10:00 am on 5 station observations. Physical and chemical factors measured were temperature, pH, and brightness, DO, BOD, OD, TDS, TSS, Phosphate and Nitrate. The results showed that there are 17 phytoplanktons genera were found in Ranu Pani, while in Ranu Regulo there are 16 genera with the highest abundance of the genus Dictyosphaerium. There are 13 and 10 genera of Zooplankton found in Ranu Pani and Ranu Regulo row, with the highest abundance of genus Arcella. Benthos are found in Ranu Pani consisting of 7 families with the highest abundance of the family Bulimidae and there are 3 families in Ranu Regulo, with the highest abundance of family oenagrionidae. Diversity of phytoplankton and zooplankton in Ranu Pani is lower than Ranu Regulo, while benthos biodiversity in Ranu Pani is higher than Ranu Regulo. Water quality in Ranu Pani is lower than Ranu Regulo and based on Government Regulation No. 82/2001, generally water of Ranu Pani can be categorized as water quality class II and Ranu Regulo can be categorized as water quality class I. Genus Dictyosphaerium (phytoplankton), genus Arcella (zooplankton) and family Bulimidae (benthos) can be used as bioindicator for water quality class II. Family Coenagrionidae can be used as bioindicator for water quality class I.
