Jenis Dan Kelimpahan Fitoplankton Di Waduk Pt Perkebunan Nusantara V Sei Pagar Kecamatan Perhentian Raja Kabupaten Kampar Provinsi Riau
Phytoplankton is a primary producer organism in aquatic ecosystem and it
supplies oxygen to the waters through photosynthesis process. A research aim to
determine types and abundance of phytoplankton in the PTPN V Sei Pagar
Reservoir has been carried out on July-August 2019. Sampling taken at three
stations, namely station 1 (inlet area), station 2 (central area) and station 3 (outlet
area), once/week.The water quality parameters measured were temperature,
transparency, depth, pH, DO, free CO2, nitrate (NO3
-) and phosphate (PO4
3-).
Result shown there were 48 species phytoplankton that consist of 10 classes,
namely Chlorophyceae (14 species), Cyanophyceae (3 species), Euglenophyceae
(6 spesoies), Zygnematophyceae (5 species), Trebouxiophyceae (3 species),
Dynophyceae (1 species), Cryptophyceae (1 species), Crysophyceae (1 species),
Xantophyceae (1 species) and Bacillariophyceae (13 species). The abundance of
phytoplankton in PTPN V Sei Pagar Reservoir ranges from 6,660-33,264 cells/L.
The water quality parameters were as follows: transparency 47-54 cm,
temperatures 27-29 0C, pH 6, DO 4.77-6.92 mg/L, free CO2 6.65-13.98 mg/L,
phosphate 0.018-0.038 mg/L, nitrate 0.905-1.23 mg/L. Based on the abundance of
phytoplankton, PTPN V Sei Pagar Reservoir can be categorized as oligotrophicmesotrophic.
