Abstract
Wilayah Pengelolaan Perikanan Negara Republik Indonesia dibagi menjadi 11 daerah, salah satu yaitu WPPNRI 712 atau Laut Jawa. Salah satu pendayagunaan pada perairan ini yaitu zona perikanan tangkapnya. Penelitian ini bertujuan untuk menganalisis nilai konsentrasi klorofil-a, suhu permukaan laut, dan kedalaman yang optimal untuk puncak penangkapan ikan pelagis kecil di Laut Jawa. Beberapa proses yang dilakukan dalam penelitian ini yaitu mengumpulkan citra, pemotongan citra, ekstrak data klorofil-a dan SST, melakukan interpolasi menggunakan metode Inverse Distance Weighted (IDW), serta melakukan overlay intersect. Potensi tangkapan ikan pelagis kecil paling banyak berada di bulan Maret dan April, hal tersebut terjadi karena konsentrasi klorofil-a di Musim Peralihan I lebih rendah daripada Musim Barat yaitu sebesar 0,79 mg/m³ dan suhu air laut sebesar 30,09˚C yang cenderung stabil dan mendukung pertumbuhan plankton. Bulan Maret dan April konsentrasi klorofil-a sebesar 0,8 mg/m³ dan sst sebesar 30˚C. Ikan pelagis kecil di Laut Jawa banyak ditemukan pada kedalaman 0-200 meter. The State Fisheries Management Area of the Republic of Indonesia is divided into 11 regions, one of which is WPPNRI 712 or the Java Sea. One of the utilization in these waters is the capture fisheries zone. This research aims to analyze the optimal values of chlorophyll-a concentration, sea surface temperature, and depth for the peak of small pelagic fishing in the Java Sea. Some of the processes carried out in this study are collecting images, cropping images, extracting chlorophyll-a and SST data, interpolating using the Inverse Distance Weighted (IDW) method, and overlaying intersects. The potential catch of small pelagic fish is highest in March and April, this occurs because the chlorophyll-a concentration in the First Transitional Season is lower than the West Season, which is 0.79 mg/m³ and sea water temperature is 30.09˚C which tends to be stable and supports plankton growth. In March and April, the chlorophyll-a concentration was 0.8 mg/m³ and sst was 30˚C. Small pelagic fish in the Java Sea are found at a depth of 0-200 meters.
