Pengembangan Model Evaluasi Sistem Penyimpanan Limbah B3 Berbasis Risiko dan Kepatuhan Regulasi

Abstract

Hazardous and toxic waste (B3 waste) storage facilities in many industrial operations are often organized as a decentralized network of storage points spread across different operational areas. Such configurations frequently complicate inspection, monitoring, and regulatory oversight. This study aims to develop a generalizable evaluation model for hazardous waste storage systems that integrates risk assessment, operational performance indicators, transportation-related greenhouse gas (GHG) estimation, and regulatory compliance assessment within a single analytical framework. The model was developed through a conceptual–analytical approach that synthesizes a semi-quantitative likelihood–consequence risk matrix, a compliance matrix referring to national hazardous-waste regulations, an activity-based GHG estimation method, and a Multi-Criteria Decision Analysis (MCDA) scheme equipped with a regulatory compliance gate. An illustrative application of the model indicates that dispersed storage systems tend to fall into medium-to-high risk categories and show inconsistent compliance performance, whereas consolidating storage into fewer, centralized points is associated with lower risk categories, more uniform compliance, and reduced transportation-related emissions. The proposed model offers a structured, cross-sector tool for evaluating and redesigning hazardous waste storage systems to strengthen environmental performance and regulatory compliance.
