Status Kesuburan Berdasarkan Indeks Nygaard Di Danau Parit Kecamatan Tambang Kabupaten Kampar Provinsi Riau

---

ABSTRACT
The Nygard index can be used to determine the trophic state of waters. Nygaard
Index calculation is based on the number of phytoplankton species include in the
following groups, that is Chlorococcales, Euglenophyceae, Centric Diatoms,
Myxophyceae and Desmidiaceae. This study aims to determine the trophic state of
Parit Lake based on the Nygaard Index. This research was conducted in December
2020. There were 3 station, namely at the inlet, in the middle of the lake and at the
end of the lake. At each station 2 sampling points were determined at surface and
2 secchi depth.Sampling was carried out three times, once/week. Water quality
parameters measured were transparency, temperature, pH, nitrate, phosphate,
dissolved oxygen, and free carbon dioxide. Result shown there were 28 types of
phytplankton of Centric Diatom classes (7 types), Chroococcales (8 types),
Euglenophyceae (4 types), Cyanophyceae (2 types) and Desmidiaceae (5 types).
Phytoplankton abundance ranges from 24,768-41,472 Cel/ L. Water quality
parameters were as follows: transparency 47.5-62 cm, temperature 31°C-33°C, pH
5.08-5.33, nitrate 0.04-0.0437 mg / L, phosphate 0.033-0.049 mg / L, dissolved
oxygen 4, 4-5.71 mg / L, and free carbon dioxide from 8.48 to 10.65 mg / L.
Nygaard Index value in Parit Lake during the study ranged from 2.0-2.6,or trophic
state of Parit Lake can be categorized as mesotrophic to eutrophic.
Keywords: Eutrophic, Mesotrophic, Oxbow lake, Phytoplankton.
