Abstract

Secara garis besar, morfologi pesisir timur laut Bali dikategorikan sebagai “Mountainous Coast" yaitu pesisir yang terbentuk dari aktivitas gunung api Tersier-Resen dari gunung Agung (3.142 mdpl). Sungai-sungai yang bermuara umumnya bersifat sub radial karena pengaruh gelombang dan arus laut lebih dominan dari arus sungai, maka beberapa sungai mengalir sejajar dengan garis pantai (spit) sebelum bermuara ke laut. Pengaruh endapan sungai dan gunung api menyebabkan pesisir timur laut Bali memiliki sedimen pasir hitam, kerakal dan bongkah yang terbentuk oleh proses-proses vulkanik. Adapun tujuan penelitian ini adalah untuk mengetahui zona wilayah pesisir yang rentan terhadap perubahan iklim di timur laut Bali. Metode penelitian yang digunakan yaitu dengan Indeks Kerentanan Pesisir (IKP) dimana data-data yang digunakan terdiri dari data geospasial dan data oseanografi yang diolah menjadi angka-angka secara kuantitatif. Hasil analisa data penelitian menunjukkan, pesisir timur laut Bali dikategorikan sebagai wilayah dengan kerentanan pesisir sedang – sangat tinggi, dimana dari 20 titik pengamatan dengan panjang garis pantai ± 60 km memperlihatkan hasil IKP untuk Profil 3 dan 9 memiliki kerentanan sangat tinggi ( > 4), sedangkan untuk Profil 1, 2, 4, 5, 6, 7, 8, 11, 12, 13, 14, 16, 17, 18, 19, dan 20 memiliki kerentanan tinggi (3 – 4), dan Profil 10, 15 memiliki kerentanan sedang (2 – 3).Kata kunci: kerentanan pesisir, perubahan iklim, timur laut BaliABSTRACTIn general, morphology of the northeastern coast of Bali is categorized as "Mountainous Coast" which is a coastal that was formed by volcanic activity Tersier-Resen from Mount Agung (3.142 mdpl).The rivers that empties to the sea generally in a sub radial form due to the influence of waves and ocean currents are more dominant than the rivers, hence several rivers flowi parallelly toward the coastline (spit) before emptying into the sea. Effect of stream sediment and volcanic cause the northeastern coastal Bali contains black sand sediment, gravel and boulders were formed by volcanic processes. The purpose of this study was to determine the coastal zone areas in the Northeastern Bali that are vulnerable to climate change. The method used was a Coastal Vulnerability Index (CVI) where the data used consisted of geospatial and oceanographic data that were processed into quantitative figures. Results of analyses shows that the northeastern coastal Bali categorized as coastal regions with moderate to very high vulnerability. Among the 20 observation points along ± 60 kms coastline,the CVI in Profile 3 and 9 show a very high vulnerability (> 4), while CVI at Profile 1, 2, 4, 5, 6, 7, 8, 11, 12, 13, 14, 16, 17, 18, 19 and 20 show high vulnerability (3 – 4), and CVI at Profile 10, 15 show moderate vulnerabilities (2 – 3).Keywords: Coastal Vulnerability, Climate Change, Northeastern Bal

Abstract

According to the Hazard Vulnerability Index from BNPB, Indonesia’s National Disaster Management Authority, West Pasaman Regency is one of the area with high vulnerability index located in West Sumatra Province, where all of its coastal areas are adjacent with The Indian Ocean. Coastal erosion and extreme waves have been reported to be the most prominent hazards, beside anthropogenic factors, along West Pasaman coastal area. This research was conducted to estimate the loss of shoreline in the area, and how far it has been shifted over the years. Thus, to achieve the objective, the dynamic of shorelines from different time scales was analyzed using quantitative data (satellite images, Netherland Map of Indonesia, and Indonesia topography map), and the statistical output of DSAS (Digital Shoreline Analysis System). The results were validated by a field survey in 2011 and interviewed local people in 2015. We found the highest erosion, about 8.44 m/y, has been occurring in Sasak Ranah Pasisie District, which separate 14 Km from where the highest accretion, about 23.7 m/y, in Kinali District took place.
