Analysis of Water Quality and Distribution of Hara in Semau Strait Kupang East Nusa Tenggara

Waters of the Sawu Sea is very dynamic because it is a meeting of the two masses of water from the Indian Ocean and the Banda Sea. The upwelling phenomenon or mass agitation in cold seawater and warm surface water makes this region an area with very high water productivity. The research purpose is to inform the condition of the water quality and nutrient distribution of Semau strait whether it can be used for the cultivation of fish. The paper presents the result of study which is showed. The average temperature at the sea surface is 26.250C-28.790C; the turbidity value range from 0.66 to 4.21 NTU; The brightness from 15.6 m to 20.3 m highest brightness occurred on Station 2 is 20.3: The speed of surface currents is ranged from 0.05 to 0.065 m / sec; levels of phosphate (PO4) ranged from 0.095 to 0.352 mg / l (average 0,137 mg / l); levels of nitrate (NO3) from 0.24 to 1.31 mg / L (mean 0.42 mg / L). The lowest nitrate levels are found in Station 4 is 0.24 mg / L; Nitrite content in the waters of Semau strait ranges between 0,006- 0.108 mg / l and Ammonium of 0.424 mg / l.
