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

Abstract

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.

Estimation of Sea Surface Salinity Concentration from Landsat 8 OLI Data in The Strait of Madura, Indonesia

“…Because SSS algorithms are site-specific and time-dependent, This existing algorithm which is mainly developed and tested in water areas outside Indonesian waters may be affected by the characteristics from the location and pollutant aspects that are possibly different. Therefore, this study aims to validate the existing algorithm's performance and develop a new suitable one for the geographical conditions of the waters in Indonesia, especially in Madura Strait (Muhsi et al, 2017(Muhsi et al, , 2018(Muhsi et al, , 2020. contributed 17% of total production of 19201.9 tons-per-August 2017.…”
