This study evaluates the synergistic integration of phytoremediation using Pistia stratiotes (Kayu Apu) and microbial bioaugmentation with Effective Microorganisms 4 (EM4) for treating landfill leachate. A batch system was employed with EM4 concentrations of 0%, 10%, 20%, and 30% and residence times of 3, 6, and 9 days. The results indicate that the highest pollutant removal efficiency was achieved with 30% EM4 and a 9-day residence time, resulting in 41.5% BOD reduction, 37.3% COD reduction, and 38% TSS reduction. Additionally, DO levels increased significantly by 488.24%, indicating improved aerobic conditions, which are essential for microbial activity. These findings demonstrate the potential of integrating Pistia stratiotes and EM4 as a sustainable, eco-friendly approach to treating landfill leachate. Further research is recommended to optimize operational parameters, scale up the system, and ensure compliance with regulatory discharge standards.
