Abstract The expansion plan of Mangunsari and Dukuh Sub-districts in Sidomukti District arises from the dynamics of the community. These sub-districts are crucial to expand due to their extensive territories and high population density which hampers the government s efforts to distribute development programs equitably. This study aims to (1) understand community perceptions of the expansion plan (2) determine policy stakeholders views on the plan (3) identify stakeholders rsquo roles in the expansion and (4) analyze the technical feasibility of the expansion plan including proposing alternative government center locations. Qualitative descriptive analysis and triangulation processed primary data while quantitative analysis determined expansion feasibility based on community satisfaction surveys technical viability and centrality index. Findings indicate support from both the community and the government for the sub-district expansion plan. The territorial expansion involves stakeholders from the government community and academia. Feasibility analysis shows both sub-districts fall short in area but exceed minimum population and infrastructure requirements. Researchers propose Dusun Jangkungan and Ngawen in Mangunsari also Dusun Kembangarum and Krajan in Dukuh as central service locations post-expansion.
