Development of Empirical Model of Total Suspended Solid (TSS) by using Landsat 8 on the Coast of Bekasi Regency

Abstract

Abstract The Coastal area is transitional areas between terrestrial and marine ecosystems which are still affected by changes on land and in the sea. Various activities carried out on the coast make this area vulnerable to environmental changes that originate from natural phenomena and human activities. The north coast of Bekasi is prone to water quality degradation due to its proximity to Jakarta Bay and the mouth of the Citarum River to the Java Sea. The decline in the quality of Bekasi coastal waters can be measured by several parameters such as salinity, turbidity, brightness, chlorophyll concentration and Total Suspended Solid (TSS), the presence of organic or inorganic material. Landsat 8 can estimate the concentration and distribution of TSS spatially and temporally. This study aims to develop an empirical model for estimating TSS concentrations in the coastal area of Bekasi Regency by using Landsat 8 data. This method used a combination regression from five channels. The results showed there are four empirical models with a value of R2 of 0.5. The calculation of the accuracy value using RMSE is still high, which is around 100, but the construction of this model is better than the previous algorithm. Another alternative is to use multiple linear regression to see the relationship between the interaction variables of each band and the TSS concentration.
