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. Dissolved oxygen and pH are the parameters that most influence the presence of most of the identified zooplankton orders.

The purpose of this research is to determine the condition of waters in the Citarik River with the periphyton community as a bio indicator. This research was conducted from March-April 2019. The research method used was a survey method at 4 station points, five times sampling with a span of 7 days. The smallest periphyton abundance is in station IV which is 22 ind/cm2 and the most is in station I which is 18278 ind/cm2. Comparison of species deficit values at each station is different, this is influenced by different physical and chemical parameters. The dominance index value in the waters of the Citarik River ranges from 0.1 to 0.8 and the diversity index value ranges from 0.2 to 0.9. The results showed the Citarik River was in a mildly polluted condition.

Majakerta estuary and its surrounding waters have a high potential fishery resource which is commonly utilized by the community around the area. Fluctuation of physical and chemical parameters of the waters and fishery activities around the estuary can influence the existence of  zooplankton. This study was conducted from December 2014 to May 2015. Samples of the zooplankton were collected monthly at four stations (consisted of sea, river and estuary areas). Based on the study, zooplankton in the  Majakerta estuary and its surrounding waters consisted of six classes; i.e. Protozoa (11 genera), Crustaceae (4 genera, 1 nauplius stadia), and Rotifera (4 genera). A higher abundance was found at the sea (29025 ind./m3), while a lower  abundance was at the river and estuary (7147 ind./m3 dan 7582 ind./m3).  Based on the zooplankton diversity index, it can be inferred that the value was relatively low. There were two habitat groups, namely Station Group 1 (Station 1 and  2; river and estuary) and Station Group 2 (Station  3 and 4; sea) with influencing parameters such as  transparency, pH, and salinity.  Keywords: estuary, Majakerta, zooplankton, community structure

The parameters observed were physical and chemical parameters of waters, plankton abundance, diversity index, dominance index, species deficit, and Morisita index. The results showed that plankton was identified as many as 33 phytoplankton genera and six zooplankton genera, the spatial distribution of plankton in the Cikeruh River was different at each station, at station 1 consisted of 14 phytoplankton genera, station 2 27 phytoplankton genera, station 3  24 phytoplankton genera, station 4 25 phytoplankton genera, and at station 5 was  found 22 phytoplankton  genera. The abundance of plankton obtained ranges from 1823-5972 ind/L. Phytoplankton diversity index obtained from ranges 0.71-0.84, while the zooplankton ranges 0.17-0.32 with  phytoplankton dominance index 0.16-0.35 and zooplankton 0.68-0.83. Phytoplankton morisita index obtained from ranges 1.37-2.17, while the zooplankton ranges 1.03-2.31. Physical-chemical parameters observed as follows: Temperature 18.58ºC – 27.77ºC, light transparency 16,68 cm -31.92 cm, current 0.17 m/s -0.35 m/s, DO 3.35-8.05 mg/L, CO2 8.36 -37.05 mg/L, pH 7.53 – 8.66, BOD5 10.83 - 25.42 mg/L, Nitrate 0.18-0.26 mg/L,  phosphate 0.18-0.26.

Macrozoobenthos used as a bioindicator of the waters, this happens because of the nature of the benthos which has mpergerakan low so it got a lot of influence from the environment. This study aims to determine the condition of the river Kundur with a view the community structure of macrozoobenthos which include: species composition, abundance, diversity, uniformity and dominance as well as the physical and chemical parameters of water as a paremeter supporters. Based on the results of observations, macrozoobenthos were found during the study in the river Kundur consists of 3 phylum, 4 classes, 17 family with 11 species. The composition of the class of macrozoobenthos in the whole of the observation station consists of a Gastropod (37%), Insecta (23%), Malacostraca (20%), Polychaeta (10%) dan Malacostraca (20%). The value of an abundance ranged from 325,7 - 3309,6 ind/m3. With the value of the total abundance at Station I which is equal to 3690,1 ind/m3, Station II 3723,1 ind/m3, Station III 3692,3 ind/m3 can be categorized diversity are light polluted with the value of the index of uniformity (E) that describes the spread of the individual tends to be uniform or relatively the same. While the condition of the physical-chemical parameters and the substrate bottom of the river Kundur in general has a range of relatively homogeneous, spread evenly throughout the observation stations and still be able to support life macrozoobenthos. To the results of measurements of the parameters of physico-chemical water and substrate in the river kundur in general has a range of relatively homogeneous in the whole observation stations and still be able to support the life of the macrozoobenthos.

Zooplankton has an important role in waters, especially in the food chain, these organisms are consumers I which play a major role in bridging energy transfer from major producers (phytoplankton) to living things at higher trophic levels (fish and shrimp). This study aims to analyze the relationship between zooplankton abundance with phytoplankton and physicochemical parameters in the waters of Kastela, Ternate. The research was conducted from March to April 2017 in the waters of Kastela Ternate City North Maluku Province at 5 stations and 4 periods of sampling. Zooplankton samples were taken by filtering methods. The results showed that there were 20 zooplankton genera from 5 (five) classes namely Ciliate (4 genera), Crustaceae (8 genera), Hydrozoa (3 genera), Rotifera (3 genera), and Urocohordata (2 genera). Zooplankton abundance ranges from 1032 to 10942 cells.l-1, the highest at station 3 periods II (10942 cells.l-1), and the lowest at station 4 period I (1032 cells l-1). The range of values of the zooplankton biological indices is diversity index (0.5005 - 1.8662), uniformity index (0.6521 - 0.9601), and dominance index (0.1661 - 0, 6800). There was a low correlation between zooplankton abundance and phytoplankton abundance and physical-chemical parameters of water in Kastela waters, with determination coefficient is 0.236 and regression equation Y = 35079.107 + 0.030 phytoplankton - 791,251 temperature + 75,417 salinity - 1658,557 pH Keywords: mangroves, macrozoobenthics, organic matter
