Abstract

The abundance of phytoplankton and zooplankton have correlation with mangrove conditions in coastal area. The mangrove degradation give negative impact for abundance and diversity phytoplankton and zooplankton. The research aimed to analysis and construct prediction model of abundance and biodiversity of phytoplankton and zooplankton in mangrove ecosystem. The research used the transect method (to determine mangrove density), filtering method (to analyze abundance of phytoplankton and zoopankton) and statistical method (to develop estimation modeling of plankton abundance). The results showed that (1) the mangrove density between 250 trees/Ha - 1250 trees/Ha (2) the phytoplankton abundance were 10.675 Indv/L (in mangrove rarely) - 24.290 indv/ L (in mangrove high density), (3) the zooplankton abundance were 261 Indv/L (in mangrove rarely) -  2.204 indv/L (in mangrove high density) (4) The modelling analysis showed that (1) the phytoplankton abundance (y) = 0.0303 x2 - 22.059 x + 13004 and (2) the zooplankton abundance (y) = 0.0057x2 – 5.39 x + 1458.2, with x = mangrove densityKeywords: phytoplankton and zooplankton, mangrove density, abundance, estuary and lagoon

Abstract

Planktons  have ability to live in aquatic ecosystem, including rivers ecosystem, estuary ecosystem, lake ecosystem and ocean ecosystem. The plankton abundance is estimated by correlation with water quality both of salinity, pH, temperature and others. This research aimed to analysis plankton abundance and to analysis correlation between plankton abundance and water quality. This research was conducted in Donan River using random sampling in 10 stations. The plankton are collected  using plankton net no 25 and Lackey Drop Mikrotranset Counting (plankton analysis) and APHA (2005) to analysis water quality. The results showed that the plankton abundance ranged between 524 – 6,406 ind L-1 and best correlation with water salinity had index 0.975. Keywords: plankton abundance, water quality, Donan river, water salinity, correlation
