Coastal ecosystems play a crucial role in supporting biodiversity but are increasingly threatened by heavy metal pollution originating from industrial and domestic activities. The mangrove species A. alba possesses the ability to absorb heavy metals through phytoremediation processes, making it a promising bioindicator of environmental contamination. This study aimed to analyze the concentratio…
Industrial and shipping activities in West Dumai pose a risk of heavy metal contamination in coastal waters, potentially leading to bioaccumulation in organisms such as Geloina erosa and Cerithidea obtusa. This study aimed to determine the accumulation of lead (Pb), copper (Cu), and zinc (Zn) in the soft tissues of both species and to compare the concentrations between species and sampling stat…
Coastal areas have high potential for natural resources, but the intensity of their utilization often leads to physical environmental changes. One of the significant impacts is land subsidence and sea level rise, which trigger tidal flooding (known as rob floods). This study aims to determine the rate of sea level rise based on tidal data analysis from 2015 to 2024, and to predict inundation ar…
Global warming is caused by increasing greenhouse gas emissions, particularly CO₂, and can be controlled through carbon sequestration by vegetation, including mangrove trees.
