This study examines the siting of a new police facility in Dlanggu within Indonesia's land-use and spatial-planning framework (RTRW 2012-2032) and related statutory constraints, focusing on access, utilities, environmental conditions, and social acceptance. We apply a GIS-enabled multi-criteria decision analysis (MCDA) that standardizes more than twenty indicators - accessibility and road hierarchy, land status and value, spatial-plan conformity and protected rice fields (LSD), parcel area, soils and hazards, utilities, population, and environment - on a 1-5 scale; consensus weights are obtained through a Modified Delphi with domain experts, scores are aggregated using a weighted-sum model, field observations verify context, and sensitivity checks vary high-salience weights by ± 10-15%. Five candidate sites are assessed - Subdistrict Office complex (Alt-1), Segunung opposite the fertilizer plant (Alt-2), Segunung soccer field (Alt-3), Segunung near the cemetery (Alt-4), and the former Dlanggu Community Health Center in Pohkecik (Alt-5) - and the weighted matrix ranks Alt-5 first (355), followed by Alt-3 (326) and Alt-1 (297), while Alt-2 and Alt-4 tie at 276 and are ordered with the pre-specified tie-break rule; Alt-5 leads because of strong performance on high-weight legal-spatial and environmental criteria together with advantages in accessibility and water availability. Framed as an academic assessment, the study provides transparent and reproducible evidence identifying Alt-5 as the most suitable option under the tested criteria and statutory constraints, with the findings intended to inform evidence-based decision-making rather than prescribe implementation. © Published under licence by IOP Publishing Ltd.
