Total Suspended Solids (TSS) in the waters reflect the amount of solid particles suspended in the water. High TSS levels can reduce water quality, cause the death of aquatic organisms, and lead to sedimentation. This study aims to measure the TSS concentration during high and low tides, analyze the differences, and assess the water quality status of Muara Ulak Karang. Observations were made …
Seagrass ecosystems are part of the coastal ecosystem, so they are geographically linked to the land area. Therefore, changes in environmental conditions will have an impact on the condition of seagrass ecosystems. Threats to seagrass ecosystems on the east coast of Bintan Island come from human activities on land and in the coastal water environment itself. The aim of this study are to analyz…
The Dumai City region is one of the areas currently designated as a busy industrial area, transportation route, and international port. This situation puts significant pressure on the marine waters of Dumai City due to the waste generated. The main source of marine pollution comes from oil spills, whether from ship operations, offshore drilling or ship accidents. Pollution from oil spills in th…
