Photosynthesis is produced from phytoplankton organisms which have chlorophyll pigment. One of the water parameters is chlorophyll. The concentration of chlorophyll can describe the high primary productivity of a waters because it is related to the abundance of phytoplankton. Phytoplankton act as primary producers 3, 4 . One way to observe the concentration and distribution of chlorophyll is to use remote sensing technology. Remote sensing technology allows the coverage of the observation area to be wider, making it easier to map the distribution of chlorophyll in a waters.. Materials and Methods: This study used level-3 chlorophyll image data with the Standard Mapped Image (SMI) type from the Visible and Infrared Imaging Radiometer Suite-Suomi National Polar-Orbiting Partnership (VIIRS-SNPP) sensor which can be accessed on the website https://oceancolor.gsfc.nasa.gov/l3/. The resampling implementation in this study used the Nearest Neighbor Method. Results: Overall, the chlorophyll concentration in West Kalimantan Province was in the range of 0.45-20 mg/m3. The change of seasons and hydrological conditions of the waters, namely the influence of the river was the cause of the high concentration of chlorophyll in the area. Conclusion: The concentration of chlorophyll in the coastal areas of Kalimantan shows the highest concentration value. Where the high concentration is more dominantly influenced by the input from the river which participates in carrying the nutrients needed by organisms.

The coastal area will become a very important area and its condition will be greatly influenced by activities on land 1 , such as mining, agriculture, deforestation, and others 2 . Coastal areas are intertidal, subtidal, and are in the exposure area with a depth of 200 m directly with the mainland. The condition of this area is always inundated by sea water. Furthermore, West Kalimantan is one of the provinces in the Indonesia which has waters which are often exposed to environmental impacts due to human activities. Photosynthesis is produced from phytoplankton organisms which have chlorophyll pigment. One of the water parameters is chlorophyll. The concentration of chlorophyll can describe the high primary productivity of a waters because it is related to the abundance of phytoplankton. Phytoplankton act as primary producers 3, 4 . In addition, chlorophyll concentration is also one of the most frequently used parameters as an indicator of water fertility 3, 6 . The main focus on changes in chlorophyll over a long period of time is the hydrological and biological characteristics of an aquatic environment, which means that waters are different from one another 7 . In addition, non-seasonal maximum chlorophyll values can also be found in coastal areas which are the result of the association of upwelling in these waters, the availability of nutrients from river run-off and geostrophic circulation 8 . And in coastal areas, the distribution of chlorophyll is very important to understand environmental conditions 9 . One way to observe the concentration and distribution of chlorophyll is to use remote sensing technology. Remote sensing technology allows the coverage of the observation area to be wider, making it easier to map the distribution of chlorophyll in a waters 10 .
