The results of the study showed that the project was financially feasible based on all the parameters evaluated. The development project, which is funded through the 2025 Pangkalpinang City Regional Expenditure Budget (APBD), is an innovative approach in sustainable infrastructure development by utilizing recycled plastic waste materials.
