STUDI PARAMETER FISIKA KIMIA AIR PADA AREAL BUDIDAYA IKAN DI DANAU TONDANO, DESA PALELOAN, KABUPATEN MINAHASA
ABSTRACT: The purpose of this
research was to analyze the physical and chemical parameters of waters
(temperature, turbidity, pH, dissolved oxygen, nitrate, phosphate, ammonia and
BOD) around net cage culture area at Peleloan Village, Minahasa Regency and to
determine the suitable culture site supporting optimal growth of fish. water
quality was measured at three sites. Temperature, turbidity, and pH were
measured in situ while dissolved oxygen, nitrate, phosphate, ammonia and BOD
were analised in laboratorium. Research results showed water temperature at all
observation sites ranged from 25.5-28.2 0C, turbidity 2.02-3.15 m, pH 6.8 –
8.2, DO 7.41-7.77 mg/L, nitrate 0.3-0.5 mg/L, phosphate 0.00-0.4 mg/L, ammonia
0.13-0.77 mg/L. Based on water quality standard criteria stated in PP No. 82,
2001, temperature, turbidity, pH, DO and nitrate at fish culture area were
suitable for floating and stick net cage cultures but ammonia at all sites of
observation, phosphate at site I at 0.5 m from the bottom and BOD at site III
at 0.5 m from the bottom were exceeding the standard criteria.
