Effect of differences in cocopeat, hydroton, and husk charcoal as an eggplant planting medium (Solanum melongena) on the absorption of ammonia (NH 3 ), nitrite (NO 2 ) and nitrate (NO 3 ) dumbo catfish (Clarias sp.) water cultivation in aquaponic system

Abstract Dumbo catfish known as freshwater commodity which its culturing has been done throughout every region in Indonesia. Compared to other freshwater commodity, dumbo catfish has a fairly higher nutrient content, higher economical value, faster growth and easier maintenance. There are various ways to culture dumbo catfish, one of them is by using aquaponic system, which described as a combination of hydroponic and aquaculture in closed water recirculation system. Aquaponic system uses various type of planting media for filtering water, so that ammonia and nitrite are reduced then modified as nitrate, where nitrate absorbed by plants. This study uses 3 different media: cocopeat, hydroton, and husk charcoal. This study aims to investigate whether three previous media can absorb ammonia, nitrite, and nitrate in dumbo catfish culturing using aquaponic system, also figuring out the most effective one. This study uses RAL method with 4 treatments: control (P0), cocopeat (P1), hydroton (P2), husk charcoal (P3) repeated 5 times. The main parameter are ammonia, nitrite, and nitrate, then analyzed using ANOVA. The result showed 3 different media absorbed ammonia, nitrite, and nitrate significantly, with husk charcoal as the most effective media with ammonia, nitrite, nitrate level 0,59 mg/L, 0,37 mg/L, and 4,99 mg/L respectively.
