Abstract:
The water quality consists of Salinity, Dissolve Oxygen, Total Dissolve Solid, pH
and Temperature. The improvement of water quality is important for the
community and the authorities especially regarding the marine environment
inhabited by marine life. This matter is not only to protect or preserve the marine
ecosystem but also to guarantee human food sources such as fish, shrimp,
shellfish, and others. Antifouling paint particles' (APPs) impacts on processes for
repairing, cleaning, and painting hulls are still mainly studied. APPs are usually
carried out in boat sheds, shipyards, and marinas, and can transport and deposit
in sedimentary layers after their environmental input. Depending on several
variables, such as the usage of coating paint, the removal technique, and the
deposition time, APPs offer pollution with very high compositional variation. The
aim of this study was to identify the Water Quality Index and to analyze the trend
of natural antifouling. implementing Canadian Council of Ministers of the
Environment (CCME) calculation to collect the data for water quality meanwhile
implementing linear regression to analyze the statistical analysis of trend. This
study intends to provide the latest water quality index of Sungai Manjung and the
trend of natural antifouling for different additive applications. The result found that
the water quality index for Sungai Manjung is good according to the CCME WQI.
