Penentuan Kandungan Nitrogen dari Beberapa Jenis Pupuk Urea Menggunakan Metode Kjeldahl

Abstract

Urea is a source of nutrient nitrogen needed for plant growth so that as one of the main parameter in determining its quality is dependent on its nitrogen content. In the present study was carried out checks on the various types of nitrogen fertilizer product Urea. Urea nitrogen in the fertilizer analysis performed using the Kjeldahl method through the stages of destruction, distillation, and titration. From the results of three kinds of fertilizer products obtained were analyzed on urea nitrogen levels between 45% -46%. The analysis suggests that urea is in accordance with the standards set out the terms of the quality of SNI 02-2801-2010 .
