Abstract

This study develops a comprehensive five-dimensional Regional Resilience Index (Indeks Ketahanan Wilayah/IKW) for Bogor Regency, Indonesia, integrating governance capacity and social capital dimensions alongside traditional human development, food security, and disaster risk indicators. Stakeholder-derived weights through the Analytic Hierarchy Process (n=25 experts) yielded the following priority ranking: Human Development (0.28), Disaster Risk (0.24), Food Security (0.22), Governance Capacity (0.15), and Social Capital (0.11), with consistency ratio CR=0.073. Spatial analysis across 40 subdistricts revealed significant heterogeneity (CV=18.7%), with k-means clustering identifying three distinct resilience typologies: High (8 subdistricts, IKW>65), Moderate (24 subdistricts, IKW 51-65), and Low (8 subdistricts, IKW<51). Comprehensive validation achieved: Cronbach's alpha 0.78, MAPE 1.12%, cross-validation RMSE 2.87, Monte Carlo 90% confidence interval of +/-3.2 points, and significant outcome correlation with post-flood recovery times (r=-0.67, p<0.01). Baseline IKW 2025: 58.42 (Moderate). Multi-scenario projections to 2030: baseline 63.15, optimistic 68.24 (High category transition), pessimistic 55.78. The framework provides actionable guidance for evidence-based regional development planning.

Abstract

This study develops and implements the Green Economy Index (GEI) as an instrument for measuring green economy transition in Bogor Regency. Using a composite index methodology adopted from OECD and UNDP best practices, the GEI integrates 15 indicators across three pillars: economic (6 indicators), social (4 indicators), and environmental (5 indicators). Data were collected from official government publications (BPS, KLHK) for the period 2020-2024. The index was constructed using min-max normalization and geometric mean aggregation. Model validation through backtesting showed a Mean Absolute Percentage Error (MAPE) of 5.10%, classified as "Highly Accurate." Results indicate that Bogor Regency's GEI reached 50.16 in 2024 ("Moderate" category), with the Social Pillar performing best (62.49), followed by Environmental (50.46) and Economic (40.03). Scenario projections suggest the GEI could reach 61.76 by 2030 under moderate assumptions (CAGR 3.53%). This study provides an evidence-based framework for green economy policy formulation at the regional level.
