      Abstract
      Habitat bentik merupakan lingkungan hidup di dasar perairan yang meliputi berbagai macam substrat seperti pasir, lamun, pecahan karang, batu, dan terumbu karang. Serta ekosistem mangrove yang berupa kelompok tumbuhan yang terdiri dari beberapa jenis pohon mangrove yang tumbuh pada area yang dipengaruhi oleh pasang surut air laut. Penelitian ini bertujuan untuk mengklasifikasikan habitat bentik perairan dangkal dan sebaran mangrove menggunakan drone di Barat Pulau Menjangan, Taman Nasional Bali Barat. Metode yang digunakan yaitu klasifikasi berbasis objek atau object-based image analysis (OBIA) dengan algoritma support vector machine. Diperoleh 452 frame foto udara dengan resolusi spasial 2,5 cm/pixel untuk memetakan 5 kelas habitat bentik dengan didapatkan kelas pasir dengan memiliki luasan 7.32 ha, kelas batu memiliki luasan 5.73 ha, kelas pecahan karang memiliki luasan 2.59 ha, kelas lamun memiliki luasan 9.77 ha, kelas terumbu karang memiliki luasan 4.24 ha, dan sebaran vegetasi mangrove memiliki luasan 3.12 ha. Nilai akurasi yang didapatkan pada klasifikasi habitat bentik sebesar 84.34% dan pada klasifikasi darat sebesar 82.98%.
       
      Benthic habitat refers to a living environment at the bottom of the waters that includes various types of substrates such as sand, seagrass, coral, rubbles, stone, and coral reefs as well as the mangrove ecosystem which consists of a group of mangrove plants made up of several mangrove tree species that grow in areas affected by tidal currents. This study aims to classify the bottom water benthic habitat and mangrove distribution using drones in West Menjangan Island, Bali Barat National Park. Object-based image analysis (OBIA) is the method used to this study with a support vector machine algorithm. 452 aerial photo frames with a spatial resolution of 2.5 cm/pixel were obtained to map 5 classes of benthic habitat, with the sand class having an area of 7.32 ha, the stone class having an area of 5.73 ha, the coral rubbles class having an area of 2.59 ha, the mud class having an area of 9.77 ha, the coral reef class having an area of 4.24 ha, and the mangrove vegetation distribution having an area of 3.12 ha. The accuracy value obtained in the benthic habitat classification is 84.34% and at the land classification is 82.98%.
