Analisis Kelayakan Tempat Penyimpanan Sementara Bahan Berbahaya dan Beracun di Perusahaan Foundry dengan Metode Cost Benefit Analysis
Every individual or entity that produces hazardous and toxic waste (B3 waste) is required to manage their own B3 waste. A foundry company produces B3 waste that must be managed according to the applicable regulations. However, based on observation results, there have been findings that do not comply with the Minister of Environment and Forestry of the Republic of Indonesia Regulation Number 6 of 2021 regarding Procedures and Requirements for the Management of Hazardous and Toxic Waste. The current overload condition in the temporary storage facility (TPS) for B3 waste also has the potential to have negative impacts on safety, occupational health, and the environment. This study aims to determine a feasible alternative redesign based on the value of benefits obtained and the costs incurred to improve the current condition of the temporary storage facility for B3 waste. This research uses the Cost-Benefit Analysis method with the calculation criteria being the Net Present Value (NPV) and the Cost-Benefit Ratio (CBR). The feasibility analysis results indicate that the addition of a temporary storage facility for B3 waste produces greater benefits with a calculated Net Present Value (NPV) of Rp 293,669,625.68, where the NPV value is greater than 0, and a Benefit-Cost Ratio (BCR) of 3.65, where the BCR CBR value is greater than or equal to 1. Based on the feasibility analysis results, it can be concluded that the alternative of adding a temporary storage facility for B3 waste is feasible to be implemented because it provides more benefits compared to other alternatives.
