Utricularia Aurea (lumut rayap) is an aquatic plant that has the ability to supply oxygen during photosynthesis process and eliminate pollutant material such includes organic material, nitrate and suspended solid. This study was carried out to investigate the potential of Utricularia Aurea in replacing air pump and filter in the aquarium. The effectiveness of Utricularia Aurea were tested with seven parameters such as temperature, dissolved oxygen (DO), pH value, total suspended solid, turbidity, chemical oxygen demand (COD) and nitrate for approximately 18 days. Three samples of aquarium that have the same volume of water were prepared as to compare the effect of using Utricularia Aurea with conventional system. It was found that Utricularia Aurea can produce natural source of oxygen in the aquarium. Results Utricularia Aurea showed that the optimum value produced for DO is 1.40mg / L, pH is 6.41, total suspended solids is 155mg / L, turbidity is 37.05 NTU, COD is 146mg / L and nitrate is 0.139mg / L. Thus it is believe that Utricularia Aurea has the potential in increasing the oxygen level in aquarium than that of the conventional system and also economic as it can be found easily
