The vulnerability of housing on the north coast of Banda Aceh to disasters from the sea

Abstract

Abstract Alue Naga is an example of a coastal village in the northern city of Banda Aceh which was severely damaged during the earthquake and tsunami in 2004, but until now there has been no maximum environmental improvement and mitigation for this coastal settlement. The ideal initial mitigation study to be carried out for coastal settlements is to analyze the physical vulnerability of housing as a physical structure characteristic that determines the potential damage to disasters. This study uses a qualitative descriptive method with data collection through observation, a global positioning system, interviews and questionnaires. Data were analyzed using geographic information system techniques to determine the spatial condition of the area. Assessment of the potential vulnerability of housing in each cluster of Alue Naga settlements is obtained by scoring and weighting methods for variables that contribute to the level of disaster vulnerability, namely the type of building construction, the shape of the ground floor of the building, and the orientation of the building to the coast. The results showed that the potential vulnerability in each cluster was different for each variable being reviewed, there were clusters that were vulnerable, more vulnerable, and very vulnerable to the threat of disasters from the sea. It takes serious action from stakeholders to further improve protection and mitigation against disasters from the sea in the northern coastal settlements of Banda Aceh City with structural mitigation and non-structural mitigation.
