Abstract

Ujung Pangkah Gresik is a reasonably dynamic area in the growth of turbidity levels in coastal beaches. As an area that has the estuary of the River Bengawan Solo, then Ujung Pangkah each year will experience the sedimentation process, one of which is the result of the movement of the river flow. This study aims to find the best mathematical model as an illustration of the total dynamics of the dissolved solids occurring in the area. The method used is a linear regression analysis of several selected models such as linear model, exponent, logarithm, polynomial degree 2, polynomial degree 3 and power model. The independent variable used in this research is the reflectance value of the Aqua Modis Level 2 from satellite imagery at wavelength 412 nm, 531 nm, and 645 nm.  The results obtained from this study are the ability of Aqua Modis satellite imagery in mapping the total suspended solids, besides that it can also be used to predict changes in the total value of suspended solids by calculating remote sensing algorithms that produce optimal mathematical models, where the model used is the polynomial model degree 3 and the logarithmic model based on choosing a high correlation value of the model that is 0.75 obtained at a wavelength of 645 nanometers
