Status Trofik Waduk Bandar Kayangan Lembah Sari Kecamatan Rumbai Pesisir Kota Pekanbaru Berdasarkan Index Nygaard

---

Nygard Index can be used to determine the trophic state of waters. Calculation of this index is based on the number of phytoplankton species that are belonged to these following groups, namely Desmidiaceae, Euglenophyceae, Chlorococcales, Centric diatom, Pennate diatom and Myxophyceae. To understand the trophic state of the Bandar Kayangan Lembah Sari Reservoir, a research has been conducted in March - April 2018. There were four sampling stations, namely station 1 (in the inlet, from the Ambang River), station 2 (in the inlet from the Merbau River), station 3 (in the middle of the lake) and station 4 (in the dam). In each station there were three sampling points, in the surface, in the middle of water column, and in the base of the river. Sampling were conducted 3 times, once/week. Water quality parameters measured were phytoplankton, transparency, temperature, pH, nitrate, phosphate, Dissolved oxygen and free carbon dioxide. Results shown that there are 26 species of phytoplankton present, namely Class Desmidiaceae (6 species), Division Euglenophyceae (2 species), Chlorococcales order (10 species), Centric diatom order (6 species), and Class Myxophyceae (2 species). The water quality parameters were as follows: transparency 65.2-74.3 cm, temperature 27.3-29.3 0C, pH 5, nitrate 0.03-0.06 mg/L, phosphate 0.03-0.10 mg/L, Dissolve oxygen 4.10-7.69 mg/L, free carbon dioxide 3.32-7.32 mg/L. Nygaard Index value of the Bandar Kayangan Lembah Sari Reservoir was 1.5 – 2.7, and it can be categorized as mesotrophic to eutrophic.
