Study of Total Dissolved Solids (TDS) and Total Suspended Solids (TSS) in Estuaries in Banten Bay Indonesia

Abstract

The estuaries of Banten Bay have sandy sediment, and their main activity is fisheries. In order to maintain fishery productivity, good water quality is required. The sandy sediment in this location can affect water conditions at the point of the residue content. This study aims to reveal solids content in the estuaries of Banten Bay. A survey was conducted in four estuaries, namely Karangantu, Wadas, Cengkok, and Pamong. TDS were measured in situ in April and October 2021. TSS was analyzed in May, July, and October 2013, as well as in April and October 2021. Other physical and chemical parameters were analyzed in the laboratory or in situ. The results were compared with the standard for sea aquatic biota. Furthermore, the regression method was used to determine the correlation of TSS and TDS with other parameters. The physical and chemical parameters that affect TDS and TSS were analyzed using Principal Component Analysis (PCA). The results show that TSS correlated with Oxidative Reductive Potential (ORP) and turbidity. PCA showed that TSS correlated with TDS, nitrate, ammonium, ORP, water depth, and water current. Although TSS exceeded the threshold, sufficient dissolved oxygen and higher nutrient still maintained water quality for fisheries in four estuaries.
