Abstract

Andesite mining activities cause land degradation that requires revegetation efforts for ecosystem restoration. This study aims to evaluate the ecological feasibility of bamboo as an alternative revegetation species for post-mining sites compared to conventional pioneer plants through a systematic literature review. Analysis was conducted on 45 relevant scientific publications from indexed academic databases, focusing on adaptability, soil improvement, erosion control, and contribution to biodiversity. Results show that bamboo has significant advantages in root systems (fine root biomass 1.1-4.5 kg m⁻³), erosion control effectiveness, and carbon sequestration potential (6-13 Mg ha⁻¹ year⁻¹). Bamboo also demonstrates high adaptability to marginal land conditions and provides sustainable economic value through selective harvesting without damaging the root system. Compared to conventional pioneer plants, bamboo provides more stable long-term contributions to post-mining ecosystem restoration. This study recommends the use of bamboo as a primary component in andesite post-mining land revegetation programs in Indonesia.

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.
