Abstract

Research with the title of the use of silica chitosan with glutaraldehyde crosslinking agents as a matrix in the making of slow release urea fertilizer has been done. The purpose of this research was to determine the physical and chemical properties of slow release fertilizer coated with chitosan-silica matrix and also glutaraldehyde with a concentration of 1%, 1.5% and also 2% (v/v). Physical properties are known by SEM where it has been seen that the matrix has covered the fertilizer, for the chemical properties of slow release fertilizer can be analyzed from functional groups by FTIR to see the interaction between fertilizer, matrix and glutaraldehyde crosslinking agents. Slow release fertilizer has also been tested for nitrogen release levels. From the test, the composition of slow release urea fertilizer with chitosan-silica matrix and glutaraldehyde 1% (v / v) is more stable than the matrix with glutaraldehyde 1.5% and 2% (v / v).
