Abstract
A study of land suitability evaluation based on physical environment, disaster and social implications for settlement areas has been conducted in Banda Aceh, Indonesia. The study aims to identify the basic physical environment for the settlements. It also identifies and confirms the locations of settlement areas that are prone to disaster. Furthermore, it also analyzes the awareness level, reasons and perception of the residents in those high-risk residential areas. Finally, the research results should be able to recommend the proposed plan to reduce disaster risks. The concept of land suitability evaluation adopts the system by Food and Agriculture Organization (FAO) and was done by processing the spatial data using Geographic Information System (GIS) with spatial analysis. The analysis of physical environment results showed that the whole area of Banda Aceh is suitable for residential purpose. However, based on the disaster analysis, it is found that 54% of the total area of Banda Aceh is not suitable for settlements (risky), and out of them, 29% is a very high-risk area. The unsuitable areas became the basis for the social implications study and planning analysis of the integrated land usage. Social sampling analysis was done randomly with a sample of 414 respondents. The social implications results showed that the entire society is positively aware of the risks and impacts of living in the disaster-prone areas. They have strong reasons and justifications for staying in the areas prone to disaster. The reasons include their tightly knit relationship with current neighbours, possibility of bearing extra cost if they decided to move, the religious belief that disaster will happen wherever you are at any time and thus, the current area poses no problem to them, and the issue of inheritance. The public perception analysis showed that the people has high perception towards the government’s foundation and support. The suitability of residential area based on the physical environment and perception of community becomes the basics for the planning of residential areas in order to reduce the impact of disaster. The protection strategies include the building of protective sea wall, greenbelt and terracing that are suited to the local nature condition. The building of escape buildings and evacuation routes is also recommended in the residential areas. The escape buildings are recommended to be built in mosques and schools, taking into account the religious belief that mosque is the best place to seek shelter when it was previously not damaged in the 2004 tsunami that hit Aceh. In some areas, the relocation of residential areas to safer places should be made a priority in the long term for the purpose of reducing the risk of disaster in the future.
