AbstrakIndonesia merupakan salah satu negara yang dilalui oleh pertemuan tiga lempeng aktif, yai- tuLempeng Indo-Australia, Lempeng Euro-Asia, danLempengPasifik. Kondisiitumenjadis- alahsatupenyebab seringterjadinyabencanaalam, khususnyagempabumi. Padatanggal 7 Desember 2016 Kota Aceh kembali diguncang gempa bumi dengan kekuatan 6,5 skala richter. Gempa bumi tersebut mengakibat ratusan bangunan mengalami kerusakan. Saat ini teknologi penginderaan jauh sangat berperan dalam melakukan identifikasi kerusakan akibat gempa. Penelitian kali ini akan berfokus pada identifikasi kerusakan bangunan yang diakibatkan oleh gempa bumi dengan menggunakan citra satelit beresolusi tinggi, yaitu citra Pleiades yang diambil tanggal 7 Desember 2016. Metode yang digunakan untuk identifikasi kerusakan bangunan adalah metode Object Based Image Analysist (OBIA). Pada proses klasifikasi, metode OBIA memandang objek tidak hanya berdasarkan nilai piksel saja melainkan berdasarkan bentuk, luasan, dan tekstur disekitarnya. Berdasarkan penelitian ini didapatkan bahwa metode OBIA terbukti dapat mengidentifikasi kerusakan bangunan pasca gempa bumi secara cepat.Kata kunci: OBIA, Citra satelit, Klasifikasi, Kerusakan pasca gempa bumi Abstract277 Jalan Ganesha No.10, Kota Bandung, Jawa Barat 40132 Indonesia e-mail: [email protected] is located in a meeting point of three active tectonic plates, the Indo-Australian Plate, Euro-Asia Plate, and the Pacific Plate. This condition causes frequent occurrence of natural disasters, especially earthquakes. On December 7, 2016 Aceh was hit by an earth- quake with a magnitude of 6.5 richter scale. The earthquake affected damaged hundreds of buldings. Nowadays remote sensing technology can be used to identify damage caused by the earthquake. This research is focused on post-earthquake damage identification using high resolution satellite imagery, the Pleiades image taken on December 7, 2016. The method used to identify the damaged buildings is the Object Based Image Analysist (OBIA) method. In the classification process, the OBIA method distinguish objects not only based on pixel values but also on the basis of the shape, area, and texture around them. This re-search has proven that OBIA method quickly identifies the damage buildings caused by the earthquake.Keywords: OBIA, Satellite Imagery, Classification, Post-Earthquake Damage
