Abstract

Aims: This study aims to explore the key issues and potential for implementing Green Infrastructure (GI) in the Tallo River area of Makassar, the largest city in Eastern Indonesia. Given its strategic location near the city center and its extensive undeveloped wetlands, the Tallo River region presents a valuable opportunity for sustainable urban development. The research emphasizes the need for integrated planning that addresses natural, economic, and social dimensions, positioning the Tallo River as a multifunctional resource capable of delivering diverse environmental benefits. Methodology and results: Using Geographic Information Systems (GIS) as a decision support and spatial analysis tool, this study evaluates environmental and socio-economic characteristics of the Tallo River area within the Green Infrastructure framework. Spatial data were analyzed to identify and map existing ecological functions, climate adaptation potential, and flood mitigation capacities. Through this process, various GI components and their functions were classified, and priority zones for Green Infrastructure implementation were delineated based on overlapping environmental and social values. Conclusion, significance and impact study: The findings highlight the critical role of GIS in supporting integrated urban planning and environmental management. Conceptualizing the Tallo River area as a multifunctional green space offers a pathway to enhance ecological resilience, address climate risks, and improve urban livability. This study provides actionable insights for policymakers and urban planners, reinforcing the significance of spatial analysis in guiding sustainable development strategies in rapidly urbanizing regions.

Abstract

Aims: This study aims to investigate the effect of binder variations on the compressive strength of eco paving blocks composed of four layered materials-rice husk, quartz sand, gravel, and activated carbon-each with a thickness of 6 cm. Methodology and results: The application is directed toward wastewater treatment using the rain garden method. Laboratory experiments were conducted to obtain reliable performance data. The results show that cement-bonded paving blocks demonstrate superior performance compared to those using fly ash binders. Cement adhesives ensured strong cohesion between layers, with blocks maintaining integrity during demolding without signs of damage or porosity. In contrast, paving blocks with fly ash binders required longer drying times due to the high moisture absorption of quartz sand, and they exhibited brittleness caused by weak adhesion. Extended curing was necessary before fly ash could adequately bond the base materials. Conclusion, significance and impact study: Quantitative findings revealed that paving blocks with cement adhesives achieved an average compressive strength of 836.25 MPa, higher than the 696.25 MPa of fly ash-bonded blocks. These results imply that cement remains the more effective binder for eco paving blocks in rainwater runoff and wastewater treatment, while fly ash requires optimization to improve its bonding performance. Eco-paving provides a nature-based, sustainable, and cost-effective solution for urban wastewater management, achieving both structural durability and effective pollutant removal.
