Effectiveness biochar/CuFe2O4as a media filter for water quality in the aquaponic system of gourami with bell pepper

Abstract

In the aquaponic system, fishpond water contains ammonia derived from the rest of the feed, fish feces and fish metabolism. Ammonia at high concentrations can be deadly poisonous fish, reduced dissolve oxygen content and pH, increase biological oxygen demand and chemical oxygen demand. This study aims to determine the ability of biochar/CuFe2O4 as a media filter in the aquaponic system to reduce the concentration of inorganic ammonia such as ammonia (NH3), nitrate (NO3) and nitrite (NO2) in gourami pond water with bell pepper plants. It also measured the growth of Gourami and bell pepper growth. The results showed that the aquaponic system equipped with media filter biochar/CuFe2O4 was able to reduce the ammonia content by 91%, increase the growth of Gourami and bell pepper plants compared to the unfiltered aquaponic system which was only able to reduce ammonia by 35%.
