Produktivitas Primer Danau Tanjung Balam Desa Buluh Cina Kecamatan Siak Hulu Kabupaten Kampar Provinsi Riau Dengan Metode Oksigen
Tanjung Balam lake is an oxbow lake located around the Kampar River and receive water from that river. A research aims to understand the primary productivity based on oxygen method and the thropic state based on carbon concentration (gC/m3/day) was conducted in June-July 2019. There were three sampling stations, Station 1 (inlet), Station 2 (in the middle lake) and Station 3 (outlet). In each station there was 2 sampling points, in the surfase (15 cm) and in the water column (90 cm). Water quality parameters measurd were transparency, temperature, pH, dissolved oxygen, free CO2, nitrate, phospate concentration and phytoplankton abundance. Results shown that the primary productivity was 488.8 -681.9 gC/m3/day, transparency was 49-54 cm, temperature was 28-300C, pH was 5, dissolved oxygen was 4.03-6.56 mg/L, free CO2 was 7.92-14.59 mg/L, nitrate was 0.015-0.029 mg/L, phospate was 0.082-0.107 mg/L and phytoplankton abundance was 845,502-1,037,218 cells/L. Based on primary productivity concentration, this lake can be categorize as mesothropic.
