      Abstract
      Penyediaan informasi zona potensial penangkapan ikan diperlukan oleh nelayan untuk meningkatkan efisiensi penangkapan ikan. Penentuan zona potensial penangkapan ikan dapat diprediksi dari data hasil olahan parameter klorofil-a, SPL dan posisi kapal ikan. Tujuan penelitian ini adalah untuk memetakan sebaran kapal penangkapan ikan hasil deteksi sensor Visible Infrared Imaging Radiometer Suite (VIIRS) serta hubungannya dengan sebaran klorofil-a dan suhu permukaan laut (SPL) di Perairan Selat Madura, Jawa Timur. Data yang digunakan adalah data deteksi kapal ikan dari sensor VIIRS. Data klorofil-a dan SPL berasal dari satelit Aqua yang dipindai oleh dari sensor Moderate Resolution Imaging Spectroradiometer (MODIS). Jumlah deteksi kapal rata-rata per hari tertinggi terjadi pada bulan Agustus (musim timur) sebanyak 50 unit sedangkan deteksi terendah sebanyak 8 unit pada bulan Desember (musim barat). Deteksi kapal tertinggi ditemukan pada tanggal 24 Agustus sebanyak 177 kapal. Deteksi pada fase bulan gelap tertinggi terjadi di bulan Maret sebanyak 139 kapal sedangkan deteksi kapal pada fase bulan terang tertinggi terjadi di bulan Oktober sebanyak 7 kapal. Hasil overlay antara posisi geografis kapal ikan dan parameter oseanografi menunjukkan kapal ikan banyak terdeteksi pada kisaran konsentrasi klorofil-a 0.3 mg/m3 sampai 0.5 mg/m3 dengan jumlah deteksi kapal berturut-turut yaitu 3191, 2599, dan 1215 unit kapal dan nilai SPL 29oC sampai 31oC dengan jumlah deteksi kapal berturut-turut sebanyak 3083, 2908, dan 2166 unit kapal.
       
      Fishermen need information on potential fishing zones to improve fishing efficiency. Determination of potential fishing zones can be predicted from the parameters of chlorophyll-a, Sea Surface Semperature (SST) and the geographical position of fishing vessels. This study aimed to map the distribution of fishing vessels detected through the Visible Infrared Imaging Radiometer Suite (VIIRS) imageries and its relationship with the distribution of chlorophyll-a and SST in the waters of Madura strait. The data was fishing vessel detection data from the VIIRS sensor. The chlorophyll-a and SST data were downloaded from the Aqua satellite from the sensor Moderate Resolution Imaging Spectroradiometer (MODIS). The highest number of ship detections per day occurred in August (east season) with 50 units, while the lowest detection was eight units in December (west season). The highest detection of vessels was founded on August 24, as many as 177 vessels. The detection of the highest dark moon phase occurred in March as many as 139 vessels, while the detection of ships in the highest bright moon phase occurred in October as many as seven vessels. The results of the overlaid technique between the position of fishing vessels and oceanographic parameters showed fishing vessels most detected in the range of chlorophyll-a concentrations of 0.3 mg/m3 to 0.5 mg/m3, with the number of vessel detections being 3191, 2599, and 1215 vessels, respectively, and SPL values of 29oC to 31oC with the number of vessel detections as many as 3083, 2908, and 2166 units of ships
