Abstract

Batik industry wastewater is characterized by deep colors, strong odors, high turbidity, and the presence of hazardous substances such as heavy metals (Zn, Cd, Cu, Cr, Pb), phenols, sulfides, and organic compounds. One solution to address this pollution is through phytoremediation using the water fern (Salvinia molesta). This study aims to evaluate the effectiveness of Salvinia molesta in reducing pH levels in batik wastewater. The treatment with a residence time of 9 days proved to be more effective and efficient in lowering pH compared to the 3rd and 6th days. Linear regression analysis was conducted to assess the effect of time variations on pH effectiveness. The analysis results showed a significance value of 0.091 > 0.05, indicating that the variation in time does not have a significant effect on pH effectiveness.
