Abstract

The socioeconomic feasibility of Waste-to-Energy (WtE) facilities is analyzed through a case study in South Jakarta, emphasizing its potential as a sustainable urban waste management solution. This study evaluates the comparative costs and benefits of implementing an Intermediate Waste Treatment Facility (ITF) in three prospective locations: Sukapura (North Jakarta), Pesanggrahan, and Petukangan Selatan (South Jakarta). Results highlight Sukapura’s strategic advantage due to its industrial zoning, resulting in lower residential density, reduced social resistance, and minimized environmental costs. By contrast, higher costs are associated with South Jakarta sites due to greater population densities, leading to amplified pollution impacts. Key findings reveal that WtE facilities generate significant environmental and economic benefits, including reduced greenhouse gas emissions, improved air and water quality, job creation, and regional budget efficiencies. The integration of circular economy principles, such as waste reduction and resource efficiency, further underscores the importance of sustainable waste management strategies. However, successful WtE implementation requires careful alignment with land-use planning and community engagement to address socio-environmental challenges effectively. This study offers valuable insights for policymakers and urban planners, proposing that strategic site selection and adaptive approaches are critical for achieving long-term sustainability in waste management.

Abstract

This study evaluates the economic feasibility of developing Intermediate Waste Treatment Facilities (ITFs) utilizing Waste-to-Energy technology in Jakarta's South Service Area. A comparative analysis was conducted using two scenarios: conventional landfill management versus ITFs implementation at two potential locations—Pesanggrahan (South Jakarta) and Sukapura (North Jakarta). The research employed secondary data analysis over one month in August 2021, utilizing financial indicators including Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit Cost Ratio (BCR). Environmental and social externalities were integrated into the economic assessment. Results demonstrate that conventional landfill approaches yield negative present value of IDR 5.24 billion, indicating financial unsustainability. Conversely, WtE technology scenarios show positive economic viability: Pesanggrahan achieves NPV of IDR 441 million (IRR 12.12%, BCR 1.08), while Sukapura demonstrates superior performance with NPV of IDR 1.25 billion (IRR 16.15%, BCR 1.23). The findings establish clear economic justification for transitioning from disposal-based to resource recovery systems, with industrial zone locations offering strategic advantages for ITF development in Jakarta's waste management modernization strategy.

Abstract

instruments that price externalities. This study examines how the carbon tax under Indonesia's Harmonization of Tax Regulations Law, the Carbon Economic Value framework, and the tax architecture of public–private partnerships jointly shape the viability and environmental outcomes of natural-resource-management infrastructure. Secondary data from the outline business cases of two dam-outflow (run-of-dam) mini-hydro projects in North Sulawesi—Lolak (1.50 MW) and Kuwil (2.50 MW)—covering economic-benefit, value-for-money and risk-allocation analyses were reinterpreted through a fiscal lens. Three findings emerged, although the two cases are near-replicates rather than independent observations. First, the statutory minimum carbon-tax rate of IDR 30,000/tCO₂e, a legal floor not yet in force, anchors the carbon shadow price; economic value remained strongly positive at that floor, and the sensitivity results rather than the point estimates are the operative findings. Second, treating taxes as eliminated transfer payments contributes to the wedge between financial and economic feasibility, though unmonetized externalities account for most of it. Third, while risk transfer drives most of the value-for-money gap, tax revenue from the project company is the decisive offset—a fiscal–environmental co-benefit that attaches to private ownership rather than to the partnership scheme as such.
