Abstract
ABSTRAK Penyisihan ammonium (NH4+) pada limbah cair dapat dilakukan dengan proses pengolahan biologis dengan pertumbuhan terlekat menggunakan Aerobic Batch Reactor (FBR). FBR yang diinokulasi oleh sedimen rawa pening diumpankan dengan limbah artifisial yang mengandung konsentrasi ammonium yaitu 50 mg NH4+-N/L. FBR dioperasikan secara batch selama 7 hari dan pH berkisar 7,5-8,5. Variasi metode Pengeringan dalam pembuatan bioaktivator dan variasi sumber karbon, sehingga didapat hasil penurunan laju oksidasi ammonium (LOA). FBR dioperasikan secara batch selama 14 untuk mengetahui pengaruh fluktuasi salinitas terhadap penyisihan ammonium. Kemampuan oksidasi ammonium pada sumber karbon CaCO3 lebih baik dibandingkan NaHCO3. Hal ini didapat dari nilai LOA pada reaktor CaCO3 yaitu 5,75, 5,85, 5,81 % mg NH4+-N/L lebih besar dibandingkan pada NaHCO3 yaitu 5,74, 5,74, 5,75 mg NH4+-N/L pada reaktor A,B,C. Kata kunci: nitrifikasi, pengeringan, bioaktivator, bakteri pengoksidasi ammonium, bakteri pengoksidasi nitrit, Aerobic Batch Reactor. ABSTRACT Ammonium removal (NH4 +) in liquid waste can be carried out by biological treatment with adherent growth using Aerobic Batch Reactor (FBR). FBR inoculated by dizzy swamp sediments is fed with artificial waste containing ammonium concentration of 50 mg NH4 + -N / L. FBR is operated batch for 7 days and pH ranged from 7.5 to 8.5. Variation of drying method in making bioactivators and variations in carbon sources, so that the results of a decrease in ammonium oxidation rate (LOA) were obtained. FBR was operated in batches for 14 to determine the effect of salinity fluctuations on ammonium removal. Ammonium in the carbon source of CaCO3 is better than NaHCO3. This is obtained from the value of LOA in the CaCO3 reactor which is 5.75, 5.85, 5.81% mg NH4 + -N / L greater than in NaHCO3 which is 5.74, 5.74, 5.75 mg NH4+ -N / L in reactor A, B, C. Keywords: nitrification, drying, bioactivator, Ammonoium Oxidizing Bacteria, Nitrit Oxidizing Bacteria, Aerobic Batch Reactor
