Abstract

The research with the title usage of zeolite and chitosan composites as slow release fertilizer had been done. In this research, fertilizer was made by mixing zeolite with NaNO3 as a source of macro nutrients (nitrogen) and chitosan as a crosslinks which will later be used to provide slow release function in fertilizers. The slow release fertilizer was made by impregnating zeolite on NaNO3 and chitosan solution. Initial characterization of slow release fertilizer functional groups was identified using FTIR instruments. The results of the characterization of slow-release fertilizer functional group are known to have shifted the zeolite characteristic peaks namely Si-O and Al-O groups which indicate the presence of Nitrogen got into the fertilizer. Nitrogen release rates were identified by UV-VIS spectrophotometer. The slowest Nitrogen release rate is zeolite-chitosan fertilizer with the ratio of zeolite and chitosan is 1:1 (%w/w), while the fastest Nitrogen release produced by zeolite fertilizer.
