Spatial study of total suspended solid (TSS) for shrimp catching areas based on changes in watershed land cover and oceanographic factors in Ciletuh Bay 2017 – 2021

Abstract

The TSS in Ciletuh Bay originates from the Ci Leutuh and Ci Marinjung estuaries. This study aimed to analyze the effect of changes in watershed land cover and oceanographic factors (salinity, bathymetry, sea surface currents) on the distribution of TSS and the relationship between TSS and shrimp catch activity. This research uses remote sensing method, Budhiman Algorithm for TSS, Cilamaya Algorithm for salinity, and Maximum Likelihood Classification for watershed land cover. The results show that sea surface currents and changes in watershed land cover (forest, bare land, and shrub) affect the distribution of TSS in Ciletuh Bay. The relationship between TSS with salinity and bathymetry is negatively correlated. The existence of TSS in Ciletuh Bay causes the dominance of muddy waters so that it becomes a habitat for various types of Penaeid shrimp. The types of penaeid shrimp that are mostly caught in Ciletuh Bay are rebon shrimp and endok shrimp.
