KERAGAMAN LIMNOFITOPLANKTON DI DANAU LAIT KECAMATAN TAYAN HILIR KABUPATEN SANGGAU
ABSTRACT: The Lait lake is a
lake that serves as a source of water, a place for fishing, a transportation
route and a recreational spot that will affect the existing limnophytoplankton.
This research aims to determine the composition, abundance and diversity of
limnophytoplankton, as well as the physical-chemical conditions of the
limnophytoplankton habitat in the Lait Lake. The study was conducted from
August to December 2014. The sampling location was divided into six stations.
The results of the research found 51 genera of limnophytoplankton that were
included in five divisions (Chrysophyta, Chlorophyta, Cyanophyta, Euglenophyta
and Phyrrophyta) and 6 classes (Bacillariophyceae, Chrysophyceae,
Chlorophyceae, Cyanophyceae, Euglenophyceae, and Dinophyceae). The diversity
index value (H’) of the limnophytoplankton in the Lake was included in the
category of medium (1.2498-2.1353), and the dominance index (D) was low
(0.1866-0.4601) and the evenness index (E) was medium (0.3804-0.6161). The
physical-chemical condition of the body of water of the Lait Lake was still
capable of supporting the life of the existing limnophytoplankton.
