Abstract

The condition of the Porong River has experienced a decline in water quality caused by detergent pollution containing surfactants. Accumulation of surfactants that have not been well-degraded can have negative impacts on the aquatic ecosystem. The aim of this research is to analyze the water quality parameters and surfactant concentrations in the Porong River, as well as to determine their correlation. The method used in this study is the descriptive survey method. Data collection was carried out at 3 stations using purposive sampling method. Data were collected in three replicates. Based on the data obtained from the water quality parameter measurements, the temperature ranges from 27.8 to 29°C, TDS levels range from 249.9 to 652.1 mg/L, TSS levels range from 4.1 to 37.9 mg/L, pH values range from 6.7 to 6.8, DO concentrations range from 5 to 5.6 mg/L, nitrate concentrations range from 1.09 to 1.23 mg/L. The results of surfactant measurements in the water range from 3.6 to 7.8mg/L. The relationship between water quality parameters indicates a positive correlation or interdependence among them. Furthermore, high surfactant content in the water leads to a decline in water quality, thereby adversely affecting aquatic ecosystems.
