Abstract: Adequate information is required to monitor water pollution along the coastal water of Pulau Langkawi, Kedah since anthropogenic activities as a result of tourist arrival and rapid development. Ironically, Movement Control Order (MCO) issued by government of Malaysia has hampered the monitoring activities of water quality at Pulau Langkawi since 2020. One of important beach at Pulau Langkawi is Pantai Kok. However, the information of the surface water quality over the coastal water of Pantai Kok, Langkawi, Kedah is found to be scarce. Consequently, KWQ Maps is developed for monitoring purposes of this area. KWK Map is design using the integration of water quality data and spatial interpolation method. Water quality data included the reading of surface water dissolved oxygen (DO), pH, temperature and salinity. Spline interpolation technique has been developed successfully. The developed map of has high accuracy with low error. The developed map can be used by communities such as local people that lived at Pantai Kok, concern government bodies such as Langkawi Development Authority (LADA), Department of Environment (DOE Malaysia) and Department of Fisheries (DOF Malaysia) to monitor this area effectively. This invention is found to be useful as it supports Sustainable Development Goal 14 (SDG 14: Life below water) which is to conserve and sustainably use the oceans, seas and marine resources for sustainable development.
