Abstract:
The water quality consists of several parameter to determine the WQI which
are Salinity, pH, Dissolved oxygen, Temperature and Total dissolved solid.
The usage of antifouling paint in the maritime industry to prevent the growth of
marine organisms and corrosion has raised concerns. The application of
antifouling paint results in the release of antifouling paint particles (APPs) into
the water, negatively impacting water quality. This issue may be relevant to
Sungai Manjung in Perak, where various maritime activities such as port
operations and vessel maintenance take place. The objective of this study was
to determine the water quality index and examine the trend of natural
antifouling methods. The significance of water quality management is
emphasized, and the water quality index (WQI) model is proposed as a tool for
evaluating water quality data. Environmentally friendly alternatives for
antifouling coatings are recommended. While the importance of using
antifouling paint to prevent corrosion is recognized, it is crucial to acknowledge
its adverse effects on water quality due to the spread of APPs. The CCME
WQI calculation and DOE Malaysia standard are employed to assess water
quality. This study aims to provide the most up-to-date water quality index for
Sungai Manjung and examine the trend of natural antifouling methods with
various additive applications. The findings reveal that Sungai Manjung's water
quality is poor according to the CCME WQI.
