KELIMPAHAN DAN KEANEKARAGAMAN PLANKTON DI AREA WADUK JANGARI, BOBOJONG, CIANJUR
ABSTRACT: One of the high
diversity of biota is the diversity of aquatic biota that very widespread in
Indonesia. Aquatic ecosystems is one of the aquatic resources that have
versatile potential. One indicator to determine the level of waters fertility
is the amount of plankton abundance of both phytoplankton and zooplankton.
Research conducted by field survey methods that plankton sampling at three
locations: edge and middle of reservoir and Floating Net Cage (KJA). Plankton
identification conducted at the Laboratory of Biological Science Pakuan
University. The analyzed parameters included biological parameters (primary
parameters) were index of abundance, diversity, dominance and eveness of species
of plankton, and chemical physics parameters (parameter support) is the
brightness, the temperature of Dissolved Oxygen (DO), Biochemical Oxygen Demand
(BOD), and CO2.The results of the three study sites, there are different types
of plankton are found in each study site were classified in four classes. The range
of biological index found was the diversity index (H ') = 2.806 - 6.668,
dominance index (C) = 0.71 - 1.98 and eveness index (E) = 0.67 - 1.4. Physical
parameter range were Chemical waters were pH of 7 - 7.5, Brightness of 40-90
cm, water temperature of 28 -29 °C, CO2 of 15.2 - 2.2 ppm, DO of 7.3 - 9.74 ppm,
BOD of 2,55 – 4,4 ppm.
