A s much as 32% of the total national fishery production or 2.2 million tons has come from catches in the Java Sea, even though the area of these waters only covers 7% of the total area of national waters. Fisheries productivity is related to the net primary productivity value resulting from the activity of phytoplankton or chlorophyll-a. Net primary productivity (NPP) is influenced by the presence of nutrients, light, chlorophyll-a, Photosynthetically Available Radiation (PAR) and sea surface temperature (SST). The purpose of this research is to analyze the distribution value of net primary productivity in the Java Sea by utilizing Aqua-MODIS satellite imagery using the Vertically Generalized Production Model (VGPM) method with a range of 2017-2021. The results showed that the waters of the Java Sea have quite high fertility and are classified as Eutrophic because the general monthly average from 2017-2021 has an NPP value of >750 mgC/m2/day. The value of primary productivity follows the seasonal pattern, will be high in the east moonson season and decrease in the west monsoon season.
