Spatial Autocorrelation on Public Facility Availability Index with Neighborhoods Weight Difference

Abstract. The level of regional development is marked by high availability of public facilities, such as education, health, economic, social facilities and their accessibility. A higher of index of public facility availability means a region can support human activities well, including the economic sector. Spatial patterns of public facility availability in Cianjur Regency were analized by global and local spatial autocorrelation based on the Moran’s index and the local indicator spatial association (LISA) index, respectively. A spatial weighted matrix (wij) for Moran’I and LISA calculated based on nearest neighbor, neighbor boundary length and neighbor distance. The result showed that differences in the spatial weighted matrix of Moran’s index does not affect the spatial pattern but they do affect the Moran’s I values for nearest neighbor, neighbor boundary length and neighbor distance, at 0.30; 0.22 and 0.33, respectively. Differences in the spatial weighted matrix of LISA index showed that 97% of districts have the same scatter plot and only 3% of districts have different scatter plot. The spatial pattern type of public facility evailability in Cianjur Regency is cluster where the nothern Cianjur cluster is in HH category and the central-southern Cianjur cluster is in the LL category.
