FITOPLANKTON SEBAGAI BIOINDIKATOR SAPROBITAS PERAIRAN DI SITU BULAKAN KOTA TANGERANG
ABSTRACT: Industry, homes
activites, and aquaculture around situ or lake could contaminate and affect the
water quality. This study aimed to determine the diversity of phytoplankton and
water pollution level in Situ Bulakan Kota Tangerang based on saprobite index.
The research was conducted on December 2014 until March 2015 at Situ Bulakan
Kota Tangerang. Observations were made based on 4 points sampling with three
repetitions for one day that could represented existing condition. Sampling
sites in this study were at inlet flow, middle, outlet, and alleged utilized
areas such as floating fish net. The result showed 26 species of phytoplankton from four
classes, namely 9 species of Cyanophyceae, 4 species of Bacillariophyceae, 11 species
of Chlorophyceae, and 2 species of Euglenophyceae with moderate diversity index
(H' = 1.77─2.05). Monoraphidium sp. was a species dominated in Situ Bulakan
Kota Tangerang which was found 215 individuals. So it can be said as saprobite
bioindicator. Saprobite index in Situ Bulakan Kota Tangerang showed moderate to
severe contaminated with α-mesosaprobic (0.14).
