Penentuan Kadar Nitrogen pada Pupuk Urea di Pt. Pupuk Iskandar Muda

Abstract

In order to know the content of nitrogen in urea fertilizer teh contant oh H2O must be determined (% H2O) wellas the percentape of biuret (% Biuret). Og biuret content the determination of nitrogen content is conducted using the calculation % N = ( 100 - % H2O - % Biuret) x 0.4665 + (% Biuret x 0.4077 ). From result of analysis. the calculation, the content of H2O is 0.233 %, biuret content 0.4966 % and the nitrogen content is 46 %.these results show that the nitrogen content obtained from urea fertilizer is in accordance to the nitrogen content with Standard National Indonesia ( SNI)-02-2801, 1992.
