Abstract

To find out the characteristics of sea water quality in tidal and low conditions with parameters including DO, Salinity, pH, Temperature, Turbidity, Brightness. The study was conducted from February to April 2019. The collection of water quality parameters in pangempang waters using tools contained in the laboratory at 5 station points. Results from the parameters DO, Salinity, pH, Temperature and Brightness at the research site, while for Brightness in the Laboratory of Water Quality Faculty of Fisheries and Marine Sciences. The average result of the measurement at the tide conditions on the DO parameter is obtained 5.76 mg / l, the Salinity parameter obtained 21.8 o/oo, the pH parameter obtained 6.4, the temperature parameter obtained 32.2 oC, the turbidity parameter obtained 0.27 NTU parameter Brightness obtained 2.6 meters, while the average result of the measurement at receding conditions at the DO parameter obtained 6.56 mg / l, salinity parameter obtained 23.2 o/oo parameter pH obtained 7, Temperature parameter obtained 31.8oC turbidity parameter obtained 1.6 NTU parameter Brightness obtained 1.33 Meters.

Abstract

Indonesia has strategic shipping lanes and abundant natural resources, one of them is petroleum. These conditions is an advantage for Indonesia, but also it give challenges for the around ecosystem. In March 2018 there was oil spill accident in Balikpapan Bay. This incident brought bad impact for ecosystem around and people too. Based on these the research set out to monitoring the direction of distribution oil spill, the method can use remote sensing technology to search it with Sentinel 1A imagery. The image analysis used thresholding digital number. The results obtained the direction oil spill is spread out to east direction in area about ±82.579 km2 (01 April 2018). While on 13 April 2018 the oil spill there was still covering area about ±​​26,896 km2.
