Water is one of the essential elements for human life, as it plays a crucial role in various aspects of life. Therefore, the fulfillment of the need for adequate clean water is one of the basic rights of the community that must be guaranteed. This study aims to analyze the characteristics of Polyethersulfone (PES) based membrane with the addition of Silver Nitrate (AgNO₃) as an alternative material in water treatment applications. The modification was done through molding method with 25 kV DC electric field and AgNO₃ concentration variation of 1%, 1.5%, and 2%. Characterization was carried out through tensile testing (ASTM D638) Type IV: 2008 Standard Test Method for Tensile Properties of Plastics, Scanning Electron Microscope (SEM), and Clean Water Permeability (CWP). The results showed that the addition of AgNO₃ had an impact on mechanical strength and water permeability. Membranes with 1% AgNO₃ concentration showed the highest tensile strength and water flux, at 5.0009 MPa and 6.117 L-m-²-h-¹-bar-¹, respectively. Meanwhile, an increase in AgNO₃ concentration caused particle agglomeration, pore irregularity, and a decrease in porosity and mechanical strength. SEM observations revealed differences in microstructure between the concentration variations, where the membrane with 2% AgNO₃ showed a rough texture and uneven pore distribution. These results suggest that the use of AgNO₃ in optimum levels can increase the effectiveness of membranes in water treatment applications.
