Status Trofik Danau Bakuok Di Desa Aur Sati Kecamatan Tambang Kabupaten Kampar Provinsi Riau Berdasarkan Trophic States Index (Tsi)
Several activities in Bakuok Lake contributed the input of organic and anorganic matter that affects the water quality, especially nutrient concentration in waters. A research aims to understand the trophic state of Bakuok Lake based on TSI has been conducted in June-July 2019. There were three stations namely station 1 (plantation area), station 2 (residential area) and station 3 (fish cage area). In each station, there were 2 sampling points, in the surface (0.15 m) and 2 Secchi depth (1.74 m). Sampling were conducted 3 times, once/week. Water quality parameters measured were total phosphate, chlorophyll-a, transparancy, dissolved oxygen, CO2, pH and temperature. The value of water quality is as follows: the total phospate was 0.10-0.22 mg/L, chlorophyll-a 12.00-14.43 μg/L, transparency: 58-87 cm, dissolved oxygen: 6.57-7.54 mg/L, CO2: 9.37-13.86 mg/L, pH: 5, temperature: 29-31oC and TSI (Trophic State Index) value: 62.54-68.00. Based on TSI value, the Bakuok Lake can be categorized as moderate to eutrophic.
