Abstract

The brackish water ecosystem is a transitional zone between freshwater and seawater, rich in biodiversity and possessing vital ecological functions. This study was conducted at Charlita Beach, North Gunungsitoli, using field observation methods with a qualitative approach. The results revealed the presence of Rhizophora mucronata mangroves, characteristic fauna such as silverside fish, mangrove crabs, and sea snails, as well as abiotic conditions including calm salty water and muddy substrates. Local tourism activities provide positive economic impacts but require proper management to avoid damaging the ecosystem. This study emphasizes the importance of protecting and sustainably managing brackish water ecosystems.

Abstract

Water quality is a crucial factor affecting ecosystem sustainability and the socio-economic impacts of aquatic resources. This study reviewed academic literature to assess the state of water quality in Indonesia, identify the main causes of pollution such as domestic, industrial and agricultural effluents, and evaluate the effectiveness of existing management. The findings show that a number of water bodies, including the Citarum River and Lake Limboto, have suffered significant quality degradation due to eutrophication and heavy metal pollution. Weak regulations, lack of community involvement, and limited institutions exacerbate this condition. Therefore, collaborative and innovative approaches involving government, communities and the private sector are needed to achieve adaptive and sustainable water management.
