ABSTRACT

Many parameters are used to determine the quality of waters, one of which is Total Suspended Solids (TSS). In addition to direct data measurement and field sampling, TSS concentrations can also be estimated from satellite data by developing models based on the reflectance of the light received by the sensor. This article aims to compare two available empirical and semi-analytic models that can estimate TSS concentrations in Bekasi coastal waters using Landsat 8 and Sentinel 2 satellite data. The empirical model was made in 2018 in Bekasi coastal waters, while the semi-analytic model was created in 2004 in the Mahakam coastal waters. As a validation using field data from the Bekasi coastal waters, taken in 2019. The results showed that the semi-analytic model has a smaller error value than the empirical model, with RMSE 51.4 mg/l and 585777.2 mg/l respectively. The result indicates that the semi-analytic model can better estimate TSS even though it is applied at different times and locations. In contrast, the empirical model shows a very high error even though it is used in the same area when the empirical model was created. For further study, we tried to apply the semi-analytic model to the Sentinel-2 image, and it was found that the semi-analytic model also has good capabilities with a lower RMSE value of 44.1 mg/l. In conclusion, the semi-analytic model is better for extracting TSS information than the empirical model.
