Mapping and Analysis A Distribution of Sulfate Concentration at the Sea Surface of Madura Strait Using Geographic Information System (GIS) Based on Landsat 8 OLI Data

For concrete planners and salt farmers know the distribution of sulfate in sea water becomes very important as a basis for the manufacture of concrete and as a planning analysis of salt-making. Based on this need to be done mapping the distribution of sulfate concentrations in surface sea water. In addition to the way the analysis in the laboratory, suspected sulfate can be done using an estimation algorithm as a remote sensing technique that results are presented in the form of geographic information systems. With remote sensing techniques will be obtained regional information sulfate at the sea surface since using Landsat 8 satellite recording results.The mapping of sulfate in the straits of Madura Island with Landsat 8 OLI imagery on July 26, 2018, obtained the minimal value was 2078.89 and the maximal value 2429.89.The highest sulfate concentration is in the Ujung-Kamal port area.When using SNI 2847: 2013 / ACI 318M-11 sulfate exposure in the Madura Strait includes a class of S2 with severe severity.
