KOMUNITAS PHYTOPLANKTON DAN PRODUKTIVITAS PRIMER DANAU SELAIS KAMPUS BINA WIDYA UNTUK RANCANGAN HANDOUT BIOLOGI SMA

Abstract

Abstract: This study aims to determine the phytoplankton community and
primary productivity as the quality of watering, as well as to produce a handout design
as teaching materials in biology learning in class X SMA. This research was conducted
in July-August 2020 in the waters of Danau Selais, Bina Widya Campus, Riau
University and the Laboratory of Biology Education, FKIP, Riau University. This study
used 2 designs, namely using a survey method with the steps as descriptive quantitative
in data collection and handout design. The parameters measured include physical,
chemical and biological parameters. The sampling of phytoplankton communities was 4
points of observation with 3 samples, while the primary productivity was carried out by
the dark-light bottle method. 18 species of phytoplankton in the waters of Danau Selais,
Bina Widya Campus, Riau University and 719 individuals. The abundance of
phytoplankton ranges from 22453.20-985444.60 ind / liter which indicates that the
waters of Selais Lake are categorized as moderate fertility waters with good water
quality. The phytoplankton diversity index value ranged from 2.30 to 3.61 and the
evenness value of phytoplankton was 0.53-0.62 which indicates that the phytoplankton
in Selais Lake was quite even. The primary productivity of Danau Selais at Bina Widya
Campus reaches Eutrophic fertility levels of 1,010.38 mgC / m3 / day. The parameters
of Lake Sealis chemical physical factors include temperature ranging from 28.7-29.1
0C, pH of water ranging from 6.55-6.63, brightness level of 46 cm and total suspended
solid, namely 18-22 mg / L. Based on the potential analysis, the results of the study were
designed to be handouts as teaching materials on ecosystem materials for Biology
learning in class X SMA.
