At crumb rubber plant, leum storage emits high concentration of  ammonia that strength odor and dangerous to healthy workers. This research occurred to remove ammonia from leum storage using biofilter coloum 23L packed with mixed of top-soil, peat-rubber leaves and sludge. The result shows that this biofilters can remove ammonia  from inlet concentration at 4 - 20 ppm to  outlet concentration less than 4,7 ppm (average of 1,1ppm below regulation limit of 2 ppm). The biofilter packed with top soil performs  to ammonia removal efficiency average of 89% and ammonia-removal capacity at 0,36 g-N/kg-dry-material/d. The biofilter packed with mixed of top soil and rubber leaves performs  to ammonia removal efficiency average of 85% and ammonia-removal capacity at 0,60 g-N/kg-dry-material/d. The biofilter packed with mixed of top soil and sludge performs  to ammonia removal efficiency of 99% and ammonia-removal capacity at 0,36 g-N/kg-dry-material/d. The biofilter packed with mixed of top soil and sludge indicated the most stable on ammonia removal capacity and the lowest oulet ammonia at an average of 0.1 ppm.</p&gt;}, number={1}, journal={Jurnal Ilmu Pertanian Indonesia}, author={Yani, Mohamad and Purwoko. and Ismayana, Andes and NurcahyaniPuji Rahmawati and Pahlevi, Derin}, year={2012}, month={May}, pages={58-64} }
