Disposal Sites Determination for the Purpose of Solid Waste Management Optimize by using Geographic Information System (Gis)

Abstract

Solid waste is a waste generated every day. The amount of solid waste generation depends on the total area of housing and services, the area of the places, and activities. The increase in population, housing and services in the area has resulted in the generation of solid waste. The solid waste should be disposed of to prevent the spread of disease and to keep the environment clean. Normally, solid waste will be disposed of in landfill sites. In four districts in Negeri Sembilan that is Jelebu, Jempol, Kuala Pilah and Tampin, the existing landfill in these areas have reached semi-critical status and the capacity is about to reach the maximum level. Therefore, this study was undertaken to proposed the most ideal and effective new solid waste landfill based on the distribution of housing in an area using the Geographic Information System (GIS). GIS serves as a hardware device that stores information and databases of the area and analyzes data to produce the output required by the user. In addition, this study was conducted to investigate and determine the criteria and weighting factors taken into account in determining the location of landfill sites. In addition, this study also conducted to identify the optimization of disposal of solid waste and the type of new landfill proposed. Some analyzes such as Analysis Geoprocessing, Model Builder, OD Cost Matrix, Network Analyst and Service Area has been carried out to obtain an ideal location to serve as a solid waste disposal site. Based on the analysis, the new landfill can cover 242 of housing areas within 25 kilometers from the landfill compared to the existing landfill that only covered 165 of housing areas only. Finally, the siting of the landfill using GIS application is the best system in helping the user to determine the new landfill in such a fastest way.
