Abstract
Air limbah memiliki kandungan pencemar yang beragam salah satunya adalah nitrat. Senyawa nitrat adalah bentuk senyawa nitrogen yang merupakan senyawa yang stabil. Senyawa ini dapat berasal dari buangan industri bahan peledak, pupuk dan cat. Secara alamiah kadar nitrat relatif rendah, tetapi kadar ini dapat menjadi tinggi sekali pada air tanah di daerah-daerah yang diberi pupuk yang mengandung nitrat. Pada penelitian ini digunakan limbah artificial, denitrifier, dan beberapa reagen yang digunakan untuk analisa parameter utama yaitu Dissolved Oxygen (DO), pH, Nitrat (NO3-N), dan Karbonat. Variabel yang digunakan adalah variasi konsentrasi nitrat, variasi proses, dan pemberian katalis. Variasi konsentrasi nitrat yang digunakan adalah 20 mg/L, 40 mg/L, 40 mg/L, 60 mg/L, 80 mg/L, dan 100 mg/L. Variasi proses yang digunakan yaitu proses autotrof dan heterotrof. Katalis yang digunakan adalah selenium. Reaktor yang digunakan adalah reaktor denitrifikasi. Mikroorganisme yang digunakan adalah Thiobacillus denitrificans. Data penelitian diambil setiap hari untuk parameter Analisis Dissolved Oxygen (DO), pH, Nitrat (NO3-N). Berdasarkan uji statistik diperoleh pengaruh proses secara autotrof tanpa katalis sebesar 47,27%. Pengaruh proses secara heterotrof tanpa katalis sebesar 9,66%. Pengaruh proses secara autotrof dengan katalis sebesar 15,99%. Pengaruh proses secara heterotrof dengan katalis sebesar 0,89%.

Wastewater has a variety of pollutants, one of it is nitrate. A nitrate is a form of nitrogen compound which is a stable compound. This compound come from industrial explosives, fertilizers, and paints. Naturally, the level of nitrate is relatively low, but this level can be very high in groundwater in areas that are given fertilizer containing nitrates. In this research, artificial, denitrifier and several reagents were used to analyze the main parameters, namely Dissolved Oxygen (DO), pH, Nitrate (NO3-N), and Carbonate. The variables in this research are variations in nitrate concentration, process variation, and catalyst administration. Variations in nitrate concentration used were 20 mg / L, 40 mg / L, 40 mg / L, 60 mg / L, 80 mg / L, and 100 mg / L. The process variations used are the autotroph and heterotroph processes. The catalyst used is selenium. The reactor used is a denitrification reactor. The microorganism used is Thiobacillus denitrificans. The research data was taken every day for the parameters of Dissolved Oxygen (DO), pH, Nitrate (NO3-N) Analysis. Based on the statistical test, the effect of autotrophic processes without catalyst is 47.27%. The effect of heterotrophic processes without catalyst at 9.66%. The effect of the autotrophic process with the catalyst is 15.99%. The effect of the heterotrophic process with the catalyst with a catalyst is 0.89%.
