KELAYAKAN LOKASI BUDIDAYA IKAN DI DANAU TONDANO DITINJAU DARI PARAMETER FISIKA KIMIA AIR
ABSTRACT: The purpose of this
study was to determine the current condition of the water quality of Lake
Tondano in terms of physical and chemical parameters in a fish farming
locations on Lake Tondano waters. Determination of sampling points at each
station is placed vertically at three predetermined points from the guard house
toward the front of the net, the distance between one point to the next point
was ± 10 m; whereas for the analysis of water quality parameters was done in
Clinical Pathology of Fish Diseases Laboratory, Faculty of Fisheries and Marine
Science, Sam Ratulangi Manado and Manado Industrial Research and Standards
Laboratory. Determination points were done by purposive sampling which refers
to the physiographic location wherever possible in order to represent or
describe these waters. The research was carried out for 6 weeks and was done in
2 stages, morning and afternoon. For direct measurement (in situ) was performed
once a week which included parameters DO, pH, temperature, and brightness,
while the laboratory tests were conducted for 2 weeks which included parameters
Nitrite, Nitrate, Iron, Chlorine, Manganese, Chloride, Sulfate, Aluminum,
ammonia and Phosphate. The results show that the locations of the four
parameters of chlorine (CL2) with range (0.1 to 0.28) and the parameters of
Ammonia with the range (0.0125 to 0.15) over the limit indicated on water
quality standards. The parameters of temperature, DO, pH, brightness, nitrate,
nitrite, sulfate, manganese, chloride, aluminum, iron and phosphate were still
in the water quality standard PP No.82 of 2001.
