Schools availability as public facilities is the government duty and responsibility. Recently, the government implemented a policy of school zoning system to increase society access to education. This policy requires children to choose school closest to their home. However, facts denoted that many problems occur with this system. School zoning techniques with buffer system become an obstacle due to the emergence of ‘blankspot area’. This study aims to provide an alternative solution of blankspot area problem in the school zoning system. This study applies network analysis using the p-median model (location-allocation analysis) and service area analysis. The network analysis used impendace modification as a standard for zoning based. ArcGIS is used as a spatial analysis tool to provide better illustration of this network analysis. The results indicated that the service area analysis was more effective in solving zoning technique problems compared to the p-median model analysis because it provided a higher percentage of demand coverage when using the same impedance constraints. However, the p-median analysis technique is able to provide a more realitic picture of the allocation for each demand (without impendance). This research emphasizes the importance of adding schools in order to optimize the school services.
