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

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.

This study took plankton and water samples carried out in 5 (five) pond plots at several locations in the UIR Agro Tourism pond. Various types of fish are maintained in these ponds. A sampling of water is done once a week starting at 08.00 until 12.30 WIB. The method of sampling is carried out by determining seven points/places in each pool. Based on the results of the study found that there are 34 species of phytoplankton consisting of 3 classes, namely Chlorophyceae (15 species), Cyanophyceae (8 species) and Bacillariophyceae (11 species). The highest abundance of phytoplankton is in pond II, which is 3027 cells / l. and the lowest phytoplankton abundance is at a station I which is 953 cells / l. Zooplankton found 2 classes of zooplankton consisting of 4 species namely Crustacea class consisting of 3 species, and Sarcodina class 1 species. The highest zooplankton abundance in an IV, while the lowest abundance in an I. From multiple regression analysis of phytoplankton obtained Fcount 2.898 <Ftable 2.90 and for zooplankton obtained Fcount 2,074 <Ftable of 2.90, which means no influence some water quality parameters (temperature, brightness, pH, dissolved oxygen, phosphate and nitrate) to plankton abundance at a 95% confidence level. The relationship between plankton and water quality is not very real and not significant. The results of observations of water quality indicate that in general the results of physical-chemical water measurements indicate that the pond waters are still classified as good and can still support the life of organisms in it, especially plankton.

Gastropods plays an important role in the food chain on seagrass ecosystem and its existence are depend on the physical-chemical factors in the seagrass ecosystem. This study aims to determine the density and diversity of gastropods associated in seagrass habitat in Nusi and Gersen coastal waters. The measurement results of some physical-chemical waters variables, are still quite good for the life of gastropods. Species composition of gastropod in Nusi at higher than at the Gersen, but instead of individual density in Gersen more higher than Nusi. Diversity index of gastropods at Nusi station is higher (3,757) than Gersen (3.053), on the contrary the eveness and dominance index are higher at Gersen station than Nusi station. Community similarity index by species is low between the two stations, which indicates that the species of gastropods at both stations is quite different. The influence of human activity and higher utilizatin of gastropods in Nusi has lowered the density of gastropods in seagrass habitat, so it needs awareness efforts on the importance of gastropods and the seagrass habitat for coastal ecosystem.
