## Abstract
Ammonia is a waste product in shrimp ponds with toxic effects on shrimp farming. It can be mitigated through the degradation of ammonia by bacteria. This study aimed to isolate and characterize biofilm bacteria from shrimp ponds and to examine their ability to degrade ammonia. Biofilm bacteria were isolated from pond materials, characterized macroscopically and microscopically, and qualitatively tested for ammonia degradation, followed by testing their ammonia degradation capability in lab-scale pond water containing 0.5ppm ammonia. Observations included bacterial growth, ammonia and nitrite concentrations, and pH measurements. The study identified 8 types of biofilm bacteria isolates, all of which showed the ability to degrade ammonia, except for isolate 8. In the ammonia degradation capability test, isolate 5 showed the highest reduction in ammonia concentration at 74%. The highest increase in nitrite concentration was observed in isolates 2, 3 and 5, recording more than 90%. The pH measurements for each treatment showed different values, with some being acidic and some being base.
