      Abstract
      Bali merupakan salah wilayah yang dinyatakan rawan bencana karena memiliki posisi geografis yang diapit oleh dua sumber gempa berupa zona subduksi dan back-arc thrust yang menjadi potensi timbulnya tsunami di wilayah Bali. Penelitian ini bertujuan untuk mengidentifikasi dan memetakan tingkat kerawanan pantai terhadap tsunami di Kabupaten Buleleng, Provinsi Bali. Peta kerawanan pantai dibuat dengan metode tumpang susun (overlay) beberapa parameter penentu kerawanan menggunakan Sistem Informasi Geografis (SIG). Parameter yang digunakan yaitu elevasi daratan, kemiringan lahan, penggunaan lahan, jarak dari pantai, dan jarak dari sungai. Tingkat kerawanan pantai terhadap tsunami di Kabupaten Buleleng terbagi menjadi lima kelas kerawanan, yaitu sangat aman (R1) dengan luas sebesar 35.466,9 ha, aman (R2) dengan luas sebesar 70.485,0 ha, agak rawan (R3) dengan luas sebesar 17.645,0 ha, rawan (R4) dengan luas sebesar 6.903,3 ha, dan sangat rawan (R5) dengan luas sebesar 438,9 ha
       
      Bali is one of the areas that prone to disasters because it has geographical position that is flanked by two earthquake sources in the form of subduction zone and back-arc thrust which is potential for a tsunami to occur in the Bali region. This research aims to identify and map the level of coastal vulnerability to the tsunami in Buleleng Regency, Bali Province. The map was carried out using the method of Geographic Information System (GIS). The parameters used in analyzing the level of tsunami vulnerability were land elevation, land slope, land use, distance from the beach, and distance from the river. The level of coastal vulnerability to tsunamis in Buleleng Regency was grouped into five classes of vulnerability, namely very safe (R1) with an area of 35,466.9 ha, safe (R2) with an area of 70,485.0 ha, moderately vulnerable (R3) with an area of 17,645, 0 ha, vulnerable (R4) with an area of 6,903.3 ha, and very vulnerable (R5) with an area of 438.9 ha.
