Abstract

Berada pada posisi yang strategis, perairan Indonesia dikenal dengan lalu lintas laut yang cukup padat dimana hal ini membawa keuntungan sekaligus ancaman. Tingginya lalu lintas laut di beberapa perairan Indonesia membuka peluang besar terhadap terjadinya pencemaran laut berupa tumpahan minyak. Tumpahan minyak tersebut bisa berupa tragedi tumpahan minyak yang bersumber dari oil platforms maupun tumpahan minyak dari sisa operasi rutin kapal. Tulisan ilmiah ini membahas penggunaan satelit penginderaan jauh (inderaja) sensor aktif dan data pendukung dari inderaja sensor pasif untuk melakukan deteksi tumpahan minyak khususnya di selatan Selat Makassar. Kondisi Selat Makassar yang sangat dinamis membawa tantangan tersendiri dalam proses pendeteksian tumpahan minyak. Pendeteksian minyak dilakukan pada citra radar Sentinel-1. Pada citra Sentinel-1, ditemukan banyak objek yang menyerupai tumpahan minyak (disebut sebagai look-alike) akibat dimanika laut di Selat Makassar. Variabel oceanografi dari satelit MODIS digunakan untuk mendukung analisis terkait keberadaan dan sumber look-alike. Hasil penelitian ini menunjukkan sinergitas data inderaja sensor aktif dan pasif dalam mendeteksi dan menganalisis tumpahan minyak. Citra radar sebagai data utama terbukti efektif mendeteksi tumpahan minyak terutama di wilayah tropis. Sementara itu juga terdapat urgensi data pendukung lain seperti kecepatan angin, suhu permukaan laut dan konsentrasi klorofil-A untuk membedakan objek tumpahan minyak dan look-alike pada citra radar.
