Correlation of Salinity and Temperature with Landsat Satellite Imagery 8 Case Study: Mayangan Coastal Probolinggo

The coastal area of Mayangan is located at an altitude of ±4 m above sea level. Mayangan District is located north of Probolinggo Regency, which is the object ofthis research case study. Several aspects that affect the Mayangan coastal area are salt content (salinity) and temperature. Salinity is the salt content in the sea, and Sea Surface Temperature (SST) is one of the parameters used to measure water quality. The increase in salinity and temperature above the tolerance range of organisms can increase the rate of metabolisms, such as plants, reproduction,and activity. This research uses the Remote Sensing method with Landsat 8 Satellite Imagery. This image is included in the medium resolution, namely 30m x 30m resolution, using salinity and sea surface temperature (SST) variables. Identification Results of Salinity Distribution in the range of32-35 per milliliter while the distribution of sea surfacetemperature (SST) ranges between 26,10 o C – 30,50 o C. The best mathematical model is in band 3, for salinity with a Logarithmic algorithm model y = -1,382ln(x) + 30,195, while the Power Algorithm against sea surface temperature (SST) model y= 21,804x-0,1. Band 3 correlation with salinity and SST is 0.625387012, which means the positive correlation isquite strong
