DISTRIBUSI NITRAT, OKSIGEN TERLARUT, DAN SUHU DI PERAIRAN SOCAH-KAMAL KABUPATEN BANGKALAN

Abstract

The conditions and the dynamics of ocean waters is influenced by several parameters, including the parameters of physics, chemistry, biology, and others. Among the important parameters are nitrates, dissolved oxygen, and temperature. Those parameters are important because it affects the quality and condition of the waters, particularly in Socah waters, District of Kamal, Bangkalan. The purpose of this study was to determine the characteristics and distribution of nitrate, dissolved oxygen, and temperature in the Socah waters, Kamal, Bangkalan. The study was conducted in October 2014 with 10 sampling points. Nitrate was analyzed using spectrophotometry with a wavelength of 410 nm performed at the Laboratory of Marine Science Trunojoyo University of Madura. An analysis showed that nitrate concentrations ranging from 0002-0022 mg/l, dissolved oxygen ranges from 6.01 to 9.04 mg/l, and the surface temperature ranges 29.0-32,7˚C. The analysis shows good condition and suitable for marine life appropriate quality standards set by the Ministry of Environment (KMNLH). Keywords:
