Analisis Kerentanan Pesisir Pulau Rangsang Akibat Perubahan Iklim
Indonesia has a huge potential for disaster related to changes in the Coastal region and small islands. As a step in efforts to mitigate and adapt to disasters in the coastal areas and small islands, the government has set a target of marine conservation areas of 20 million hectares by 2020.
Rangsang Island is one of the small islands in the Meranti Islands Regency, Riau Province, which deals directly with the battle of the Malacca Strait. Excitatory islands are almost entirely deep peatlands. Cause this region is very vulnerable due to changes in vulnerability that occur. The impact of climate change that is strongly felt on the Coast of Pulau Rangsang is abrasion and inundation (tidal flood). In addition, land changes on Rangsang Island will have a global impact. If these peatlands burn, or are degraded, various types of greenhouse gases (mainly CO, NO, and CH) will be emitted into the atmosphere that is ready to change globally.
The purpose of this study was to analyze the Coastal Zone towards the conservation of changes in the north coast of Rangsang Island by using the Coastal Vulnerability Index (CVI) model. This research was conducted in December 2018 on Rangsang Island, Kepulauan Meranti District. The Coastal Damage Index (IKP) used includes six parameters namely geomorphology, elevation, changes in coastline, significant high waves, tides and rising sea level rise.
Based on the class consideration of geomorphological and elevation parameters, around 56.25% of the Coastal Islands of Excitution are included in the very vulnerable category, around 43.75% are included in the vulnerable (high) category. Classes reflecting the coastline show that around 43.75% are in the very vulnerable class, around 6.25% are in the vulnerable class, around 25% are in the medium category, 25% in the Coastal Island of Rangsang are included in the very non-vulnerable category. High significant parameters Significant waves 100% of Coastal Island Rangsang into the category is not very vulnerable. Sea level rise parameters reflect Rangsang Island 43.75% have a vulnerable category and 56.25% are included in the security class. While the tidal parameters indicate that the Coastal Island is 100% included in the medium registration category.
Rangsang Island coast is classified as vulnerable and very vulnerable to coastal elevation and geomorphology. The results showed that 4 villages were classified as medium, 10 were classified as vulnerable and 2 were classified as very vulnerable.
