Dinamika Kelimpahan Fitoplankton Di Danau Bunter Desa Pangkalan Baru Kecamatan Siak Hulu Kabupaten Kampar Provinsi Riau
Research on the dynamics of phytoplankton abundance was conducted in July-
August 2019 at Lake Bunter Pangkalan Baru village. A study aims to know the
dynamics of phytoplankton abundance either spatially and temporally. There were
3 stations namely station 1 (inlet area), station 2 (in the middle of the lake) and
station 3 (in the end of the lake). In each stations, there were 2 sampling point, in
the surface and 2 Secchi depth. Sampling was done 4 times, once/week. Water
quality parameters measured were temperature, pH, transparency, dissolved
oxygen, free carbon dioxide, nitrate, phosphate. Result shown that temperature
29-32 oC, transparency 81-90 cm, pH 5, DO 3.42-8.22 mg/L, CO2 3.99-15.98
mg/L, nitrate 0.022-0.089 mg/L, phosphate 0.014-0.049 mg/L. Phytoplankton
abundance at the surface range 317,746-411,070 cell/L, and 2 Secchi depth range
284,416-311,080 cell/L. Temporal dynamics of phytoplankton abundance was
influenced by time while spatial dynamics of phytoplankton abundance based on
stations or depth. The dynamics of phytoplankton abundance, either spatially and
temporally was influenced by water quality such as transparency, nitrate and
phosphate.
