Abstract

Urban development and land conversion in residential areas of Makassar have increased pressure on surface water quality through domestic wastewater discharge, runoff, and reduced infiltration areas. The degradation of riparian vegetation and green open spaces (RTH) may reduce the ecological functions of urban waters, including filtering pollutants and maintaining environmental balance. Therefore, this study aimed to analyze the role of RTH vegetation in maintaining surface water quality in urban settlements using a quantitative descriptive approach. Surface water samples were collected from two rivers and one pond, while the analyzed parameters included pH, DO, BOD, COD, TSS, ammonia, fecal coliform, and total coliform based on Class II water quality standards and Pollution Index (PI) calculations. The results showed that BOD and COD exceeded the quality standards, while other parameters remained within acceptable limits. Pollution Index values ranged from 2.82 to 3.02, indicating lightly polluted conditions. Vegetation in the study area was dominated by Nypa fruticans, Sonneratia caseolaris, Rhizophora mucronata, Samanea saman, and Swietenia mahagoni, which contributed to reducing runoff and maintaining water stability. However, the vegetation had not effectively reduced organic pollution from domestic activities and land-use change. These findings indicate that green open spaces act as ecological buffers and support sustainable water quality management in Makassar by promoting vegetation conservation and improving domestic waste management.

Abstract

This study aimed to analyze the role of green open space (GOS) vegetation on air quality in densely populated residential areas of Makassar City. Rapid urban development, increased vehicle activity, and the reduction of urban green spaces have contributed to the decline in environmental quality, particularly ambient air quality, in urban settlements. The research was conducted in the Tamalanrea District at six observation points representing commercial areas, main roads, warehouse areas, and residential settlements. A quantitative descriptive method was applied through direct field measurements of ambient air quality parameters, including Sulfur Dioxide (SO₂), Nitrogen Dioxide (NO₂), Carbon Monoxide (CO), Total Suspended Particulate (TSP), and Lead (Pb), combined with vegetation observations to identify vegetation density and dominant plant species at each observation point. The results showed that ambient air quality at all observation points remained below the national ambient air quality standards. Higher concentrations of SO₂, NO₂, and TSP were found in areas with high vehicle activity, such as commercial zones, residential gateways, and warehouse areas. In contrast, residential areas with denser vegetation cover tended to show lower concentrations of air pollutants. Vegetation in the study area was dominated by species such as Samanea saman, Swietenia mahagoni, Tabebuia sp., Terminalia mantaly, and Syzygium oleina. The findings indicate that vegetation density and land-use characteristics influence ambient air quality conditions in urban residential areas. Therefore, the development and preservation of green open spaces are essential to support environmental sustainability and improve urban air quality.
