Study of Total Suspended Solids (TSS) Distribution and Salinity of Coastal Area Using Satellite Imagery for Pond Development in Pond Irrigation Areas (DIT) Sei Teras

Abstract

The Sei Teras Pond Irrigation Area (DIT) is an aquaculture zone on the coast of Central Kalimantan Province. TSS and salinity are water parameters that affect the development of aquaculture. Water quality studies and their distribution are needed to support aquaculture enhancement. This study aims to investigate the distribution of TSS and salinity in the coastal waters of Sei Teras as a source of fish pond water and fish pond development potential for the Sei Teras. This study utilized Sentinel-2 imagery which the visible spectrum was extracted based on water quality parameters using the Liu et al. algorithm. The study results show that the distribution of TSS has values between 163.27 to 326.68 mg/l, and salinity exists in the range of 21.92 to 23.94 ppt. Calibration of the analysis results with in situ measurement data shows different values indicated by the RMSE value. The RMSE values are between 9.12 to 60.57 for TSS and 0.34 to 1.70 for salinity. The difference between result estimation and data in situ is caused by the dissimilarity of sampling time of image and image quality used. TSS and Salinity conditions support the development and improvement of DIT Sei Teras from extensive traditional to semi-intensive.
