Abstract : Ammonia (NH₃) is one of the common pollutants present in broiler chicken houses and produced by the breakdown of nitrogen in chicken feces. High ammonia levels are detrimental to the air quality inside the broiler houses and may affect the health and productivity of the animals. In this experiment, the researchers sought to determine the efficiency of a corona plasma reactor in lowering the levels of ammonia inside an open-house broiler chicken house. The experiment was done in a chicken house measuring 10 meters long and 5 meters wide, wherein there are four corona plasma reactors located strategically in certain areas. Ammonia levels were determined at five different points (points A, B, C, D, and E) for 90 minutes. From the findings, the effects of varying voltage and power on plasma current were observed to increase as both parameters increased since the strength of the electric field enhanced gas ionization. The effect of varying frequency was found to result in a reduction in plasma current as the frequency increased. Ammonia testing for concentration was observed to decrease from 2,5 ppm to 0,1 ppm within 90 minutes, indicating a reduction efficiency of 96%. Based on these findings, it can be concluded that corona plasma has the capability of producing reactive species that break down NH₃ into stable molecules.

Keywords : Ammonia; Open House System; Corona Discharge Plasma; Indoor Air Quality; Reduction Concentration.
