The Citarum River is the longest river in West Java Province which is used for various human activities to produce a load of waste input into water bodies which cause changes in the physical and chemical parameters of the waters that will affect the life of aquatic organisms that live in it, one of which is zooplankton. Zooplankton can be used as a water bioindicator because it has a high level of sensitivity to pollution, especially in freshwater. The purpose of this research is to determine the physical-chemical quality of the water in the Citarum River and its influence on the structure of the zooplankton community in this environment. The research was carried out from August 2020 until October 2020 with a purposive sampling method. Sampling was carried out at 5 stations with 6 repetitions every 1 week. The parameters observed were physical and chemical parameters of the waters, an abundance of zooplankton, diversity index, and dominance index. The results showed that the composition of zooplankton in the Upstream Citarum River was 15 genus consisting of 2 phyla. The abundance of zooplankton obtained ranged from 21 - 51 individuals/L. The Simpson diversity index (D) obtained a range between 0.59 - 0.73 for the high category. The dominance index obtained ranges from 0.27 to 0.41 for the low category.

A study on inventory and diversity of phytoplankton in the floating-net-cages area of Lake Maninjau has been carried out from five different sites (Muko-muko, Koto Kaciak, Kubu Baru, Tanjung Sani, Sigiran). Sampling was conducted in the surface water and incubation zone (Secchi depth) from each site, start from November 2017 to January 2018. This study aims to identify phytoplankton species and diversity, also habitat quality due to floating-net-cages activities in Lake Maninjau. A standard method was followed in this study to identify phytoplankton species and calculated the biological index. Other factors recorded including the characteristic of aquatic habitat, temperature, TDS, TSS, and pH. From the observation, we found 17 species of phytoplankton consist of 4 Classes. Phytoplankton diversity index (H') ranged from 2.42 to 2.62 with the highest diversity index found in Muko-Muko and Sigiran (2.42 and 2.62) while the lowest in Koto Kaciak and Tanjung Sani (1.63 and 2.18). Phytoplankton Evenness index (E) ranged from 0.41 to 0.67 with the highest value found in surface water and incubation zone in Muko-Muko and Sigiran (0.64 and 0.67, respectively) while the lowest found in Koto Kaciak (0.41 and 0.60, respectively). Phytoplankton dominance index (D) ranged from 0.87 to 0.92 with the highest dominance index found in surface water and incubation zone in Sigiran, Muko-Muko, Koto Kaciak, and Kubu Baru (0.90) and Sigiran (0.92) while the lowest found in Tanjung Sani (0.89 and 0.87). From this study, we can conclude that feed residue from floating-net-cage activity causes impairment in water quality and can be detected from the physical-chemical factors of Lake Maninjau.
