lake Biru Perambahan Telawi
district in Sawahlunto regenely is
one of the lakes formed by ex-coal mining excavations by PT. AIC Jaya as for
the ex-coal mining lake, it contains high levels of sulfur with a low pH. With
the formation of holes in the area after coal mines that are filled with water
when it rains or from springs for years, of course. plankton grouped into
phytoplankton (vegetable plankton) and zooplankton (animal plankton).
Phytoplankton only consists of algae which are microcopically shaped, all
phytoplankton forever live in water as plankton. The purpose of this study was
to determine the phytoplankton composition and phytoplankton genus based on the
chemical physics factors of water found in the lake Biru Perambahan Telawi district in Sawahlunto regenely.
This research was conducted in April 2018 in lake Biru Perambahan Telawi
district in sawahlunto regenely. This research was conducted by descriptive
survey method. Sampling was carried out at IV stations representing all lake
areas and each station carried out III replications. sample identification was
carried out in the biology laboratory of STKIP PGRI West Sumatera. From the
results of the study found 15 genera consisting of 4 classes, 7 orders, 11 families.
The highest density of phytoplankton found in the genus Zygnema is found at
station IV, which is 37.43 individuals/liter of the lowest density found in the
genus Cylindrocapsa at station I, which is 0.17 individuals/liter. the highest
frequency is at station II as many as 11.02 and the lowest frequency is at
station I as much as 6.31. the diversity index at station I is 1.3510, station
II is 1.8522, station III is 1.3141, and station IV is 0.9494. the highest
similarity index is at station II-IV is 81.8% while the lowest similarity index
is found at station I-III is 55%.
