Abstract


Pengetahuan morfologi dasar laut berkaitan dengan bidang oseanografi, biologi, geologi kelautan, kerusakan habitat dan sumberdaya laut. Penelitian ini bertujuan untuk mengklasifikasikan morfologi dasar laut perairan Pulau Kemujan, Kepulauan Karimunjawa. Data yang digunakan dalam penelitian ini adalah data batimetri dan citra Sentinel-2A yang diproses menggunakan perangkat lunak Benthic Terrain Modeler yang terintegrasi pada perangkat lunak ArcGIS. Hasil klasifikasi terdiri dari tujuh kelas morfologi dasar laut, yaitu: crest, valley bottom, flat, rough, valley flank, break shelf dan depression. Rough, relif positif dengan sudut curam 0,21° sampai 0,81°, dengan luas 429,36 ha (65,56%) merupakan kelas dengan area paling luas di lokasi penelitian. Kondisi tersebut menunjukan bahwa morfologi dasar perairan Pulau Kemujan cukup landai dan cenderung datar.
