This study was conducted to optimize the effect of sodium phosphate (Na?PO?) concentration and solution pH on the formation of magnesium phosphate (Mg?(PO?)?) precipitates using the Response Surface Methodology (RSM) approach. This method is used to analyze the relationship between the two variables and determine the optimal conditions that produce maximum precipitation. In this precipitation process, magnesium ions (Mg²?) and phosphate ions (PO?³-) react in solution to form insoluble magnesium phosphate compounds. The analysis results show that the pH of the solution and the concentration of Na?PO? have a significant influence on the efficiency of precipitate formation. Based on the RSM approach, the optimum conditions for magnesium phosphate precipitation were obtained, namely at a Na?PO? concentration of 15% and a solution pH of 9. Under these conditions, the maximum amount of precipitate formation occurred, indicating that this combination of parameters plays an important role in the stability of the precipitation process. This finding has significant implications in the field of environmental engineering, particularly in wastewater treatment systems containing magnesium and phosphate ions. By understanding the optimum parameters in the precipitation process, the design of wastewater treatment systems can be improved to increase their efficiency and effectiveness in reducing contaminants. In addition, this data can be used as a reference in the development of simulation software that supports design optimization of sewage treatment equipment. This study also provides.
