Status Trofik Danau Buatan Bandar Kayangan Lembah Sari Kecamatan Rumbai Pesisir Kota Pekanbaru Provinsi Riau Berdasarkan Kelimpahan Fitoplankton

Trophic Status indicates the level of water fertility and it can be calculated based on nutrient, transparency and other biological activities that present in the water. This study has been conducted in December - January 2019 and aims to determine the trophic status of the reservoir based on the type and phytoplankton abundance. There were 4 stations, namely: in the Ambang River (station 1), and Merbau River (station 2), station 3 in zone transition and station 4 in zone lacustrine. Sampling were carried out 3 times, once/ week. The quality of water parameters measured is temperature were transparency, depth, acidity (pH), dissolved oxygen, free carbon dioxide (CO2), nitrate (NO3), phosphate (PO4). The type of phytoplankton found 4 were classes namely Bacillariophyceae (2 species), Chlorophyceae (9 species), Cyanophyceae (4 species) and Dynophyceae (1 species). Phytoplankton abundance ranged 5,147cells/ Liter – 6,454 cells/Liter. Water quality parameters were as follows: transparency 57 – 60.2 cm, temperature 31-32oC, pH 5, dissolved oxygen 5.38 – 8.31 mg/L, free carbon dioxide 0.208 – 0.293 mg/L, nitrate 0.075 – 0.096 mg/L. Based on phytoplankton abundance , the waters of the Bandar Kayangan reservoir can be categorized oligotrophic.
