• Dynamic System Modeling of PM₂.₅ Emissions and Concentrations in DKI Jakarta Based on BAU, Moderate, and Aggressive Scenarios (2026) · Equivalent Jurnal Ilmiah Sosial Teknik · doi

  The long-term effectiveness of different intervention levels on PM₂.₅ concentrations has not been sufficiently evaluated using an integrated and dynamic approach. There is a need for a system dynamics model to project PM₂.₅ emissions and concentration trends in DKI Jakarta under different scenarios.

  Future studies should investigate the relationship between PM₂.₅ concentrations and other environmental factors, such as meteorological conditions. The research should be extended to other regions to understand the generalizability of the findings. Future studies should explore the development of strategies for mitigating the impacts of land use changes on environmental and human health.
