dc.description.abstract	Free ammonia is the ammonia that is not perfect react with carbon dioxide during the process of manufacture of urea in the synthesis unit. Free ammonia is not bonded directly to urea but attached to the grain. Free ammonia would be toxic to plants at certain concentrations. Therefore the content of free ammonia in the urea granules have a reference quality Indonesian National Standard (SNI-2801-1992) and Organitation International Standards (ISO), ie, 150 ppm. From the results of my research at PT. Iskandar Muda fertilizer obtained the average levels of free ammonia that is 100.905 ppm are still in line with benchmark quality standards.	en_US
