Spatial interaction of land use or commonly associated with externalities of land use is one factor which drives the land use change. A recent study indicates that the significance of land use externalities create sprawl-leapfrogged urban spatial pattern in the fringe of Jakarta Metropolitan. This inefficient development activity gives more pressure to the conservation area and the productive agricultural sites in the southern fringe. Therefore a proper land use policy to protect those important sites should be formulated. The proper formulation however, needs precise information about the extent or the maximum distance in which land use externalities are still affecting the land use change. The development of spatial statistics especially the semivariogram analysis enables the formulation of this distance, which is the aim of this study. Based on the range of the estimated semivariogram function, this study indicates that in the fringe of Jakarta Metropolitan, the furthest distance for interaction between developments is 29.2 km, while the interaction between open space or agricultural uses are still in effect at mostly 29 km. Those results will be useful to predict the future land use change in the area, based on the recent land use pattern within the distances. © 2015, Public Administration and Public Services Academy of Economic Studies.
