Abstract

Population movement is a form of spatial interaction between regions. This phenomenon arises as
a logical consequence of the heterogeneity of regional development that occurs. Pandeglang
Regency as an underdeveloped area should not be left behind because of the many leaks of spatial
interactions that are more directed outside this district. Investigating the daily mobilization of the
population internally is important in determining which sub-districts play a role as a destination for
economic activity. The basic data used include the survey origin destination of Banten Province in
2019 and data on Potential Villages (Podes) 2019 in the Pandeglang Regency. The method used is
the Scalogram method to determine the Sub-District Development Index (SDI) and the gravity
method to analyze spatial interactions. The Hierarchical classification was carried out on the SDI
variable, the number of daily movements (density), and the distance between districts. This is done
to see the intensity of the daily movement of the population according to density, distance, and
SDI hierarchy class. The spatial interaction magnitude is estimated based on the population
estimation parameters and SDI through the natural logarithmic transformation (ln) of the gravity
method formula. The results show that the highest average population movement occurs in the
high-density hierarchy leading to the sub-districts of the SDI 1 hierarchy. The sub-districts of
Cadasari, Munjul, Patia, Saketi, and Sukaresmi as sub-districts from which spatial interaction
originate will produce positive intensity values when compared to other sub-districts. Cadasari
Sub-District will provide a positive spatial interaction value when it becomes the goal of the daily
movement of the population.
