Konsentrasi Klorofil-A Di Danau Teluk Petai Desa Buluh Nipis Kecamatan Siak Hulu Kabupaten Kampar Provinsi Riau
Abstract
The research of chlorophyll-a concentration conducted in June-July 2020 at Lake
Teluk Petai Buluh Nipis village. A study aims to understand the concentration and
throphic state Teluk Petai lake based on chlorophyll-a. There were 3 stations
namely station 1 (inlet area), station 2 (in the middle of the lake) and station 3 (in
the end of the lake). In each stations vertically there were 2 sampling point, in the
surface and 2 Secchi depth. Samplings were carried out three times with ten days
interval. Result shown that temperature is 30-31oC, transparency 61.66-70 cm, pH
5, DO 4.17-5.23 mg/L, CO2 7.98-10.65 mg/L, nitrate 0.038-0.054 mg/L,
phosphate 0.051-0.062 mg/L. Result shown that the chlorophyll-a concentration
ranged from 7.63-14.37μg/L. Chlorophyll-a concentration influence the water
quality such as transparency, nitrate and phosphate concentration. Based on the
chlorophyll-a concentration, the waters at Lake Teluk Petai can be categorized as
mesothrophic.
Keywords: Mesotrophic, Trophic State, Water Quality, Depth.
