Settlement development based on land suitability

Abstract

The needs of settlements land are higher due to the increasing population, but the lands-availability in urban areas is getting narrower. Land use continues to grow as the initial process for the expansion of the city, its movement will out from the city centre to the periphery. Therefore, it is necessary to study the suitability land and develop the principles of the location planning of housing development. The research method using analytical hierarchy process (AHP) to calculate the weights, Geographical Information System (GIS) was used to create land suitability map, and overlay analysis result used to describe the principle of settlement location based on land suitability. The results show that 1) most suitable land for housing development is 637,75 hectare, low suitable land is 952,75 hectares and unsuitable areas of 781.5 hectares 2)The principles of settlement location based on land suitability are a)Clean water, available piped water network with adequate water quality terms smells, taste and colour, b)Flood prone, integrated drainage system development, optimization of reservoir performance and lake as water absorption, c)Accessibility, have road infrastructure and easy access to public transportation, d) Availability of land, not located in protected areas or technical irrigation, e) Availability of basic public service.
