      Abstract
      Sumber limbah cair laboratorium yang berasal dari berbagai bahan kimia berpotensi menyebabkan pencemaran air. Penelitian ini bertujuan untuk menguji efektivitas fitoremediasi menggunakan eceng gondok (Eichhornia crassipes) dan kiambang (Pistia stratiotes) dalam menurunkan kadar amonia, nitrit, dan nitrat pada limbah cair laboratorium. Variasi massa tanaman (50, 100, 150, 200, dan 250 g) diaplikasikan pada 10 liter air limbah selama 14 hari. Hasil penelitian menunjukkan bahwa eceng gondok dengan massa 100 g paling efektif dalam menurunkan kadar amonia (50,39%), nitrit (90,70%), dan nitrat (85,51%). Kiambang, meskipun efektif dalam menurunkan nitrit dan nitrat pada massa tertentu, menunjukkan efektivitas rendah dalam menurunkan amonia. Oleh karena itu, eceng gondok dengan massa 100 g direkomendasikan sebagai pilihan terbaik untuk aplikasi fitoremediasi dalam mengurangi kadar polutan pada air limbah laboratorium.
       
      The sources of laboratory liquid waste, originating from various chemicals, have the potential to cause water pollution. This research aims to examine the effectiveness of phytoremediation using water hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes) in reducing ammonia, nitrite, and nitrate levels in laboratory wastewater. Varying plant masses (50 g, 100 g, 150 g, 200 g, and 250 g) were applied to 10 liters of wastewater for 14 days. The results showed that water hyacinth with a mass of 100 g was the most effective in reducing ammonia levels (50.39%), nitrite (90.70%), and nitrate (85.51%). Water lettuce, although effective in reducing nitrite and nitrate at certain masses, showed a low effectiveness in reducing ammonia. Therefore, water hyacinth with a mass of 100 g is recommended as the best choice for phytoremediation applications in reducing pollutant levels in laboratory wastewater.
