| dc.description.abstract | An analysis of calcium and magnesium levels in dolomite fertilizer using
HCL hydrolysis has been carried out. The aim of this research was to determine the
good quality of dolomite fertilizer by knowing its calcium and magnesium levels. The
method used is atomic absorption spectrophotometry (SSA) using in SNI 02-2804-2005
reference with a minimum calcium content of 30% and a minimum of 18% magnesium.
Meanwhile, sample No. 55 contains 32.35% calcium and 15.39% magnesium.
Therefore, it can be said that the dolomite fertilizer in sample No. 55 was obtained in
the laboratory as a fertilizer that was not good according to SNI 02-2804-2005. | en_US |
