Configuring suitable landfill with GIS-network analyst case study municipal of Batam - Indonesia

Abstract

This study meant to apply Network Analysis in GIS to develop scenario generation model and assess alternative landfill sites in Batam City based on the economical aspects. And the best route to achieve the closest landfill. Results of this study might help the government of Batam City to consider about the landfill projects in the city. Landfill alternative selection started by unionizing the layer landuse (excluding Environment Sensitive Area), road buffer, residential, airport, and slope lower than 20%. Road topology and transit point were done afterwards (for 265 points), in order to avoid layer overlapping in the form of shapefile. Road layer (shapefile) converted to network dataset to add parameter and road specification. The analysis were done to show the size of the covered area in every 5, 15, and 30 assumed minutes. The result was alternative number three, because even it did not has the wide area covered, it has more transit point and more waste generate. In order to support this result, then OD (Original Destinations) are added and 10 furthest transit point were defined. ArcInfo Network Analysis assessed the landfill alternatives. The result was alternative number three, because it has more transit point and more waste generate even it did not the closest route and fastest time-span. Site 3 showed the more area covered then other alternative sites.
