Abstract

Zooplankton in the food chain acts as the primary consumer which connects phytoplankton as producers with organisms that have higher nutritional levels, for example nekton and benthos. This research aimed to identify zooplankton diversity and abundance in Lake Sunter. This research used a purposive sampling method to take the samples, to determine station points based on the environmental conditions of the lake. The results obtained were the identification of species from the genus Candacia, Nauplius, Eudiaptomus, Tintinnopsis, Polyarthra, Brachionus, Trichocerca, Philodina, dan Polydora. The diversity index of station 1 was categorized as medium (1.32), station 2 was in the low category (0.64), and station 3 was in the medium category (1.47). The abundance value at station 1 was 26,000 Ind/L, station 2 had an abundance value of 9,302 Ind/L, and station 3 had an abundance value of 32,500 Ind/L. In conclusion, the results of research at Lake Sunter found 9 genera of zooplankton. The diversity index of Lake Sunter was in the low to medium category, which indicates that the area has high ecological pressure and the species diversity index is low. The zooplankton abundance index value was categorized as high because each station had an abundance value above 500 Ind/ L.

Abstract

Plankton are organisms that are found living floating in the water, that move passively so they are easily carried by currents. Plankton includes two large groups, namely phytoplankton which is similar to plants and zooplankton which similar to animals. One of important benefits of plankton is an indicator of biological conditions. This research aims to determine the types of plankton and their abundance at Situ Gintung, South Tangerang City. Sampling was conducted at three points area. The samples obtained were then observed and counted under a microscope and identified using web determination. Data were analyzed using plankton diversity and abundance formulas. The research results found phytoplankton species, such as Nitzschia sp., Navicula sp., Coscinodiscus sp., Synedra sp., Staurastrum sp., Scenedesmus sp., Coelastrum sp., Oscillatoria sp., Spirulina sp., Peridinium sp., and Phacus sp. The zooplankton obtained were Nauplius sp., Eudiaptomus sp., Polyarthra sp., Brachionus sp., Trichocerca sp., and Lecane sp. The average value of the phytoplankton diversity index is 0.543 and zooplankton is 1.043. The average phytoplankton abundance index obtained is 18,808,334 ind/L and zooplankton is 32,766 ind/L. Based on the results obtained, it was concluded that there were 11 types of phytoplankton and 6 types of zooplankton. The phytoplankton diversity index is in the low category and zooplankton is in the medium category, while the phytoplankton and zooplankton abundance index are in the medium to high category, but phytoplankton abundance is more dominant than zooplankton.
