Abstract
The estuary of the Bengawan Solo River, which is in Ujung Pangkah District, has undergone many changes every year. This is influenced by several factors, one of which is the process of settling (sedimentation) from the transport of material carried by river water along the watershed (DAS). Based on this background, efforts are needed to monitor the distribution of Total Suspended Solid (TSS) in the Bengawan Solo Gresik river estuary. The purpose of this study is to determine the distribution of Total Suspended Solid (TSS) for 5 years to find the right formula to model the impact of change, so that related problems can be overcome in the future. The method developed below is remote sensing technology with Landsat 8 satellite imagery data, extracting digital number values that are converted into reflectance values to then find the optimal mathematical model algorithm with parameters from Total Suspended Solid (TSS). From the research that has been done, the following results are obtained: reflectance band 4 (red) has the best relationship value with TSS In Situ with an R square value of 0.0450. The suitable algorithm model for estimating TSS concentration is the Linear model with the equation Y = 1311.3x + 447.93. Based on the ANOVA test, Fcount = 3.621349 is greater than Ftable = 2.310225, so H0 is rejected and H1 is accepted, meaning that the average TSS in situ and image TSS from 2019 to 2023 have differences. The output of the Thematic Map of TSS Distribution in the Estuary of the Bengawan Solo Gresik River is as follows, in 2019 the highest TSS level was at the 3rd point of 664.06 mg/l and the lowest level was at the 17th point of 624.43 mg/l, in 2020 the highest TSS level was at the 19th point of 655.04 mg/l and the lowest level was at the 6th point of 604.11 mg/l, in 2021 the highest TSS level was at point 1 of 703.82 mg/l and the lowest level was at point 14 of 626.61 mg/l, in 2022 the highest level was at point 2 of 642.03 mg/l and the lowest level was at point 17 of 592.36 mg/l. In 2023 the highest level was at point 3 of 645.94 mg/l and the lowest level was at point 14 of 581.41 mg/l, based on in situ data the highest level was found at point 9 of 358 mg/l and the lowest level was at point 13 of 770 mg/l. From this study it can be concluded that Landsat 8 satellite imagery can provide an overview of the distribution of Total Suspended Solid (TSS) in river estuaries, especially for shallow waters such as Ujung Pangkah Gresik, so that in the future it can be used as an alternative in making decisions in coastal management. Keywords : Total Suspended Solid (TSS), Landsat 8, Thematic Mapping
