Keanekaragaman Fitoplankton Di Perairan Rawa Desa Sawah Kecamatan Kampar Utara Kabupaten Kampar Provinsi Riau
Phytoplankton was sensitive to the environmental changes, and therefore it might be used as bioindicator. A research aims to understand the diversity of phytoplankton in the swamp area of the Sawah Village was conducted on July to August 2018. There were 3 stations with 3 sampling points in each station. Samples were taken 3 times, once/week, in 3 different stations, namely S1 (natural area), S2 (residential area), S3 (around the plantation area). Water quality parameters measured were temperature, brightness, dept, pH, dissolved oxygen, CO2, nitrate and phospate. Phytoplankton found were consisted of 32 species that were belonged to 3 classes, namely Chlorophyceae (15 species) and Cyanophyceae (11 species), Bacillariophyceae (6 species). Phytoplankton abundance ranged from 252.67- 1.241.33 cells/L, the species diversity index (H') ranges from 2,7659–3,5726, the dominance index (C) ranges from 0.0745-0.2745 and uniformity index (E) ranges from 0.7602-0.9654 Water quality parameters values were as follows: temperature 25 - 270C, pH 4 - 5, dissolved O2 was 3.7-3.8 mg/L, CO2 was 1.7-2.7 mg/L, nitrate was 0.171 - 0.231 mg/L, and phosphate was 0.144 - 0.219 mg/L.
