Physical and Chemical Conditions of Bayur Bay Waters On the East and West Season
Abstract: Physical
construction of Bayur bay coastal area as a port was followed by a variety of
environmental issues, both physical degradation of the natural environment,
biology reduction and an increase in social problems, directly affect to water
quality decreasing in the coastal Bayur Bay. This study aims to determine the
concentration distribution of physical and chemical parameters and their
influence to water conditions on the east and west season. The method used is
descriptive method (data taken by in situ and laboratory analysis), determining
the location of sampling points based on purposive sampling method and tide
prediction by NAOtide software. The results of field survey and laboratory
measurements analysed using statistical method. The speed of sea currents on
the east season ranged from 3,48 to 24,9 cm.s-1, while in the West season flow
rate ranged from 1,4 to 57,7 cm.s-1. Rainfall in East Season ranged from 0-45
mm and The intensity of rainfall in West Season ranged from 0-30 mm.
Sea-surface temperatures in the Eastern season range between 26,2- 31.5 °C,
while in the west season SST range from 24,3 to 30,5°C. Dissolve oxygen
concentration in the east season range from 4,3 to 6,1 mg.L-1, while the west
monsoon conditions range from 4,1 to 6,4 mg.L-1. The pH values ranged from 7,4
to 8,1 in the Eastern season and ranged from 7,12 to 8,27 in the West season.
Bayur Bay water quality conditions is not much different from its value range
on the west and east season and influencing each other.
