The Synthesis of Hydrogel from Canthium Parvifolium Roxb.’s Pection for Nitrogen Fertilizer Releasing

Abstract

In this research investigation, the researchers synthesized hydrogel of pection (Pc) extracted from Canthium parvifolium Roxb and Polyvinylpyrolidone (PVP) in the ratio of 1:0.2, 1:0.4, 1:0.6, 1:08, and 1:1 using glutaraldehyde (GA) as a cross linker. The test of the free absorption capacity of hydrogel found that hydrogel absorbed water more when the absorption time was increased to the eighth hour. The study of nitrogen absorption using the Kjeldahl technique of hydrogel prepared at the ratio of PC:PVP in the ratios of 1:0.8 and 1:1 found the amount of nitrogen to be 61.59 and 53.35 percent. The test of mixing hydrogel in soil for fourteen days found the amount of nitrogen to be 22.57 and 4.11 percent. When hydrogel was mixed in tea bags and put in soil for fourteen days, it was found that the amount of nitrogen was 5.13 and 4.12 percent, respectively.
