(2016-03-31) Mulyadi; Pamukas, Niken Ayu
The study on the effect of resirculation system using various filter materials and aquaponic toward water quality has been carried out. Several filter materials used were carried out into four kinds. namely aquarium using aerators (control). aquarium using silt, gravels and palm fiber (resirculation), aquarium using mustard greens (aquaponic system), aquarium using spons (resirculation). The results of the study showed that different filter materials were significantly affecting nitrate and nitrite concentration in the catfish culture media. It was invented that treatment of resirculation system combining with aquaponic system could increased water quality parameters such as CO2 (7.99 - 11.98 mg/L), NH3 (0.02 - 0.07 mg/L), NO2 (2.43 - 0.02 mg/L), NO3 (4.32 - 0.04mg/L) respectively, but the other water quality parameters were not differ significantly. The best results were achieved at the same treatment namely absolute growth (4.01 grams), daily growth rates (1.96 %) and survival rates (91.11 %) respectively.
