The analysis primarily emphasizes Hierarchy 1, highlighting the role of these areas as key service hubs. Centrality Index Method The Centrality Method determines the most efficient locations for service centers in urban areas by analyzing the number and types of facilities in each area. This method identifies the level of centrality by comparing existing facilities, allowing for the establishment of a regional hierarchy within the Northern Medan Region. The area with the highest centrality ranking is assumed to be the optimal location for a service center. After calculating the weight and centrality index values, urban villages are grouped into five hierarchical classes based on their The analysis reveals that Belawan I Village in Medan Belawan Sub-district ranks highest with a centrality index of 351, making it the top candidate for a service center. Rengas Pulau Village in Medan Marelan Sub-district follows with a centrality index of 286. supported by its dense population and comprehensive facilities. A service center is defined as a hub offering various facilities and conveniences, making it a focal point for activity. The analysis confirms that Medan Marelan and Medan Belawan Subdistricts are crucial growth centers in the Northern Medan Region, with their respective villages.

Volume 9. Number 2, pp 109 Ae 128, 2024 CONCLUSION The scalogram analysis identified four urban villages as potential urban service centers: Besar. Martubung. Pekan Labuhan (Medan Labuhan Sub-distric. , and Belawan I (Medan Belawan Sub-distric. , all ranking in Hierarchy 1. Among these. Sub-District Rengas Pulau (Medan Marela. and Sub-District Belawan I (Medan Belawa. emerged as top candidates for urban service centers due to their extensive facilities and higher population densities, with centrality index values of 286. 56 and 351. 63, respectively. Rank size rule analysis further highlighted seven urban villages from three subdistrictsAiMabar. Tanjung Mulia. Tanjung Mulia Hilir (Medan Del. Besar (Medan Labuha. , and Rengas Pulau. Tanah Enam Hundred, and Terjun (Medan Marela. Aias having the largest populations and thus occupying Hierarchy 1. However, inconsistencies were noted between the analysis and the Medan City Spatial Plan (RTRW) for 2022-2042. While the RTRW designates Pekan Labuhan as a city service center, the analysis suggests that Besar. Rengas Pulau, and Belawan I are more suitable based on current data. Additionally, several villages, including Mabar Hilir. Tanjung Mulia. Titi Papan (Medan Del. , and others in Medan Labuhan. Marelan, and Belawan, were found unsuitable according to the analysis. In summary, the analysis reveals discrepancies between the existing spatial plan and actual potential, suggesting the need for a revision of the RTRW to better align with the identified service centers.
