This research aims to synthesize magnetite-chitosan activated carbon adsorbent and ammonia and nitrite applications for ornamental fish. Results magnetite-chitosan activated carbon have been synthesized by mixing a solution of chitosan, FeCl2, FeCl3 and activated carbon as well as with glutaraldehyde to form a crosslinker via precipitation method. Characterization of magnetite-chitosan activated carbon is done by using FT-IR and SEM. Unit experiments conducted with treatment A. 0:25 grams, B. 0.50 grams, C. 0.75 grams, D. 1 gram, respectively be repeated three times. Adsorbent synthesis of research results based on FT-IR analysis showed a group N-H, O-H, C=O, C-N, and Fe-O, while the SEM analysis showed that the morphology of magnetite-chitosan activated carbon in the form of small clots. Results for the application of the adsorbent ammonia and nitrite done using UV-VIS spectrophotometer, the result is 1 gram of magnetite-chitosan activated carbon can reduce ammonia and nitrite as much as 72.22% and 29.79%.
