Salinity and Sulphate Concentration Mapping and Analysis: Sea Surface at the Madura Island Context

Abstract

Seawater as the main raw material for making salt has the required chemical elements and impurities. One of the elements that are needed such as chloride (Cl) and the impurity is sulfate (SO4). In remote sensing the element of chloride can be analyzed through satellite imagery by first estimating the salinity which is salts in sea water where there is chloride. Whereas sulphate can also be analyzed through satellite imagery using the estimation model of the results of previous studies. From the two data, seawater is mapped in the south and north side of Madura Island to recommend better sea water based on chloride content and sulfate. The results of the mapping obtained that the waters of the island of Madura better side than the waters of the North side. Nevertheless waters of the north side is still quite good so it is still possible serve the manufacture of salt.
