PENGARUH HUBUNGAN UNSUR HARA NITRAT DAN FOSFAT TERHADAP KERAGAMAN FITOPLANKTON DI PERAIRAN TAMBAK KECAMATAN GLAGAH KABUPATEN LAMONGAN
ABSTRACT: The study
investigate the abundance of phytoplankton in Glagah District. The objective was
of the research to explore the relation of the nitrate and phosphate nutrients
to the abundance of phytoplankton in the area. The study conducted on July to
Agust 2014. The "brucin”methodwas utilized to analyzed the nitrate and
"the stano cloride”todetermine the methodphosphate.The phytoplankton
sampling applied the purposive sampling method to choose five observation
stations. The results showed that there were 25 genera from 4 classes of phytoplankton
which consists of Chrysophyceae (9 genera), Bacillariopyceae (7 genera), Dinophyceae
(5 genera) and Chlorophyceae (4 genera). The nitrate content value was about 0.176-0.598
mg/L, mean while the phosphate content value was about 0.016-0.028 mg/L. The determination
index was generated from the pearson product moment correlation was about 38.3%
(psig< 0.05) showed that there was the sufficient correlation between nitrate
nutrient and the abundance of phytoplankton, and 2% (psig>0,05) showed that
there was the very weak correlation between phosphate nutrient and the
abundance of phytoplankton.
