      Abstract
      Laut Jawa memiliki potensi sumber daya ikan yang besar. Suhu permukaan laut dan konsentrasi klorofil-a merupakan parameter oseanografi yang dapat mempengaruhi persebaran ikan. Penggunaan parameter ini dapat menganalisis sebaran suhu permukaan laut dan kloofil-a dengan memanfaatan teknologi penginderaan jauh. Tujuan penelitian ini untuk menganalisis sebaran klorofil-a dan suhu permukaan laut menggunakan sensor satelit Aqua Modis di Laut Jawa pada Tahun 2020.Penelitian ini berlokasi di perairan Laut Jawa menggunakan data citra Aqua MODIS bulanan selama tahun 2020. Penentuan nilai konsentrasi klorofil-a dan suhu permukaan laut yang sebelumnya telah diolah menggunakan interpolasi Inverse Distance Weighted (IDW). Analisis sebaran SPL rata-rata bulanan di Laut Jawa dari citra satelit Aqua MODIS tahun 2020 berkisar antara 28.5°C – 30.9°C. Penyebaran SPL di Laut Jawa mengikuti pola angin musim yang terjadi di perairan Indonesia dimana SPL cenderung turun pada musim barat dan timur serta naik pada musim peralihan 1 dan peralihan 2. Konsentrasi klorofil-a berkisar antara 0.54-4 mg/m³. Nilai konsentrasi klorofil-a setiap bulannya berfluktuasi mengikuti musim angin yang sedang berlangsung. Kata kunci: IDW, klorofil-a, Laut Jawa, suhu permukaan laut
       
      The Java Sea has great potential for fish resources. Sea surface temperature and chlorophyll-a concentration are oceanographic parameters that can affect the distribution of fish. The use of this parameter can analyze the distribution of sea surface temperature and chlorophyll-a by utilizing remote sensing technology. The purpose of this study was to analyze the distribution of chlorophyll-a and sea surface temperature using the Aqua Modis satellite sensor in the Java Sea in 2020. This study was located in the waters of the Java Sea using monthly Aqua MODIS image data during 2020. Determination of the value of chlorophyll-a concentration and sea surface temperature which had previously been processed using Inverse Distance Weighted (IDW) interpolation. Analysis of the monthly average SST distribution in the Java Sea from Aqua MODIS satellite imagery in 2020 ranges from 28.5°C – 30.9°C. The distribution of SST in the Java Sea follows the pattern of monsoons that occur in Indonesian waters where SST tends to decrease in the west and east seasons and rises in transitional season 1 and transition 2. The concentration of chlorophyll-a ranges from 0.54-4 mg/m³. The value of the concentration of chlorophyll-a fluctuates every month following the ongoing wind season. Keywords: chlorophyll-a, IDW, Java Sea, sea surface temperature
