Phytoremediation Effectiveness Azolla sp. and Ipoemea Aquatica Towards Amonia Levels Reduction in Tilapia (Oreochromis niloticus) Water Cultivation

Tilapia is one type of freshwater fish that has a lot demand in the market. Therefore, production tilapia aquaculture increasing. Increased causes decrease water quality due to large number metabolic wastes. Fish farmers usually require amount money overcome decline pond water. For this reason, it necessary apply techniques improve at an affordable cost. Azolla sp and Ipoemea aquatica are plants can absorb environmental contaminants. The research method used was experimental with untreated pool samples (control), treated kale (Treatment 1), sp. 2) combination treatment 3). Ammonia levels were statistically analyzed using SPSS application. results showed tends be effective reducing ammonia rearing spinach had higher value sample pond, which 5.99 compared 3.22 5.95.
