Hydro-oceanography Profile Condition at Tunda Island Serang District Banten Province, Indonesia

Abstract

Tunda Island has three potential coastal ecosystems, but they would not be sustainable for the organism when the oceanographic condition is under the quality standards. The research aims to study hydrooceanography as the first profile Marine Conservation Area management plans at Tunda island explains in Zonation Plans on Coastal Areas and Small Island Banten Province. In general, the waters profile condition will describe how it can contribute to the primary productivity of other organisms. Collected the sampling method was in July and November 2020, and the sampling method used purposive sampling on 45 stations across the island. The result of the data analysis from each parameter was the depth of water has ranged from 0.5-52.4±1.14 meters, water transparency from 0.5-13.3±0.25 meters, waters temperature was 29.97- 31.16±0.32 °C, DO was 6.63-8.41±0.31 mg/l, pH from 6.83-7.92±0.25, salinity was 31.6-33.8±0.55 ‰, TDS was 13.8-15.8±0.39 mg/l, conductivity was 22.7-24.8±0.36 mS/cm and ORP from 149-186±7.03 mV. Believed the difference in water quality conditions among stations to be due to differences in the typology of water conditions and currents from the Sunda Strait and the flow of particles from mainland Serang. Where northern and western sides are associated with several small islands and lead to the mainland of Serang. Wheres, south and east sides are directly waters related to the Sunda Strait. The hydro-oceanographic can be used as data and information to develop activities like MPAs plans in Tunda Island waters.
