Abstract

Due to the long molecular chain and high molecularweight of chitosan, the application is very limited. The radiation process can reduce molecular weight and shorten the molecular chain. This study aims to determine the characterization of irradiated chitosan coated on NPK as a growth stimulant for maize and to know the influence of NPK fertilizer coating with chitosan (R-1) and irradiated chitosan (R-2) on the growth and yield of corn. Chitosan before and after irradiation was characterized, including free radical analysis, changes in functional groups, thermal properties, viscosity, and molecular weight. The results showed that the form of the free radical spectrum of chitosan was peroxide radical. For functional group analysis using FTIR equipment between chitosan without irradiation and chitosan irradiated at a dose of 50 kGy showed no change in the functional group. Thermal analysis with DSC shows exothermic at a temperature of 250⁰C to 350⁰C. To determine the application of NPK fertilizer coated with chitosan (R-1) and irradiated chitosan (R-2) on the growth of corn plants. Growth parameters included the number of plants starting to flower from 50 plants, the weight of corn fruit, and the average weight of corn cobs after 60 days of planting. From the results that have been achieved, the treatment of NPK fertilizer coated with irradiated chitosan increased the weight of the corn cobs. The administration of NPK + chitosan (R1) and NPK + chitosan radiation (R-2) showed that on the 47th day after planting, almost all of the maize trees flowered at 84% and 96%, while only NPK was 54%. Corn fruit has given NPK + chitosan radiation (R-2) aged 60 days can be harvested and only with NPK 84 days old.
