THE WATER QUALITY ANALYSIS USING NATURAL ADDITIVE ON STAINLESS STEEL PLATE

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.
