Total suspended solid distribution as impact tin mining at surrounded Pangkalpinang seawater Bangka Island

Abstract

Abstract Bangka Belitung Archipelago is well known as tin mining production in Indonesia. The mining activity was performed on land and offshore area which affect the shoreline and total suspended solid distribution especially at Pangkalpinang sea water. The aim of this study is to evaluate total suspended solid (TSS) distribution and compare with oceanography parameters (current and wave). The concentration of TSS was analysed in the laboratory by gravimetric total suspended solids. This study was conducted in June- July 2022 by using survey method and IDW Interpolation. The result showed that total suspended solid have various value, ranging from 56.3 mg/l – 93.3 mg/l. Based on PP No.22 in 2021, several stations on Pangkalpinang sea waters have passed the sea water quality standard. Prolonged exposure of sedimentation will lead to shoreline changes.
