Background and Objectives: The Bakaran Batik industry is engaged in domestic textiles in Juwana district, Indonesia. The wastewater produced by the burnt batik is discharged into the environment without going through any prior treatment. Therefore, an effective and easy-to-implement processing technology is needed by the community. Phytoremediation technology is an effort to treat waste that is proven to be effective and easy to implement. This study aims to determine the effectiveness of the Pistia stratiotes in reducing Lead (Pb) levels in batik wastewater.
Methodology: The method used in this research is the type of experimental research. The research method is True Experimental with Post-test Only Control Group Design. The statistical test used is One Way Anova and linear regression test to determine the rate of degradation.
Results: showed that the Pistia stratiotes was effective in reducing lead levels of Lead (Pb) from an initial concentration of 0.042 ppm to 0.022 on a day for 48 hours, the speed of degradation was based on the linear equation - 0.0108x + 0.048, R² = 0.8526 in the treatment with Pistia stratiotes 50 grams, whereas in the 75 grams and 90 grams the Lead (Pb) concentration was not detected. Conclusions: Phytoremediation with the biological agent Pistia stratiotes is quite effective in degrading Lead (Pb) -containing batik waste.
