| Summary: | Chlorophyll-a is one of the most defining parameters of the quality of the water. The dynamics of the Chlorophyll-a concentration distribution depend on the oceanographic conditions, so it can vary according to the environmental and seasonal circumstances. This study aims to investigate the distribution of Chlorophyll-a around Kuala Perlis. This assessment was conducted by using a remote sensing technique which is from the Landsat-8 data satellite imagery to locate the distribution of Chlorophyll-a around the Kuala Perlis coastal area in 2019. ERDAS Imagine and ArcGIS software were used in processing data to see the distribution of Chlorophyll-a. The patterns of distribution of Chlorophyll-a concentration have been influent by the monsoon. From the result in 2019, the distribution of Chlorophyll-a in transition monsoon April shows the highest concentration of Chlorophyll-a with 1 (mg/m3) while the lowest was shows in transition monsoon October with 0.295476(mg/m3). Besides that, the result obtained through correlation clearly shows certain Chlorophyll-a and factors indicate that there is a negative linear relationship because the values R2 are not approximately close to +1. The high relationship appears on Northwest monsoon January – March 2019 when shows a significant correlation R2 =0.4777 for Chlorophyll-a with rainfall average and R2 =0.0005 for Chlorophyll-a with temperature average. It means that the value of Chlorophyll-a and factors influence is not acceptable and no relationship with chlorophyll-a. The result of this study will benefit by providing insight understanding and meaningful information related to Chlorophyll-a. |
