Abstract

Abstract. Ammonia in hospital wastewater comes from the process of reshuffling of amino acids by various types of aerobic and anaerobic bacteria (Aminullah et al, 2015). Large amounts of ammonia can be toxic and may interfere with aesthetics as they can produce a pungent odor and eutrophication in the surrounding area (Titiresmi and Sopiah, 2006). Therefore it takes innovation in lowering ammonia levels by using plants as biofilter. The purpose of this research is to see the effectiveness of Jirangau (Acorus calamus) and kangkung air (Ipomoea aquatica) plants in reducing ammonia (NH3) in RSUD wastewater from Bitung City. This research method is quasi-experiment with time series design. The main concern of this type of research is the effect of treatment. The results showed that the ammonia concentration at the beginning of the experiment was 3.18 mg / l. In Jirangau-covered containers, there was a decrease of ammonia content up to 0.025 mg / l (99.21%) on the 15th day and planted with water kangkung 0.042 mg / l (98.67%) on the 15th day. From these results, it is concluded that Jirangau plants are more effective than watercress plants in purifying ammonia levels in wastewater. It is therefore advisable to use aquatic plants in lowering the ammonia content in wastewater. Keywords: ammonia, jirangau, watercress.
