The design of geographic information system determination of slum area to improve villages in supporting green and clean in Surabaya City using Fuzzy-AHP method

Abstract

One of the problems of an urban area is the existence of many pockets of slum area, which certainly raises many problems for the local government and the general public. Slum housing greatly affects the environment and community sanitation, as well as urban planning. To detect slum housing problems, it is necessary to have an integrated computer information system, especially one that can be used for mature planning and able to combine spatial information system and information called the Geographic Information System (GIS). This information system is equipped with Decision Support System to recommend the determination of slum areas using the Fuzzy AHP method. Fuzzy AHP is a method that is an amalgamation of Fuzzy method and AHP method. The fuzzy type used was Fuzzy Triangle Number. The fuzzy value was defined for each alternative on each criterion using the linear membership function down, ascending the triangle as an approximation to obtain the degree of membership. The output of this system is a recommendation ranking of slum locations based on predetermined criteria.
