Chitosan co-polyacrylamide hydrogel crosslinked has been prepared by glutaraldehyde to obtain the unique material as soil remediation for agriculture applications which play a role in water storage to increase plant fertility. In this study, we examine the compositions effect of hydrogel material, the optimum concentration of glutaraldehyde as crosslinker, and hydrogel properties. Based on the results, the hydrogel successfully synthesized through chemical crosslinking methods that the 0.53 g, 1.06 g, and 1.59 g of glutaraldehyde to (0.9:5.1), (1.2:4.8) and (1.5:4.5) grams of chitosan and acrylamide were used to increase the degree of swelling properties KKPAG105 396.17% (0.9:5.1) and KKPAG205 262.51% (1.2:4.8), respectively. Subsequently, Fourier-transform infrared spectroscopy (FTIR) was characterized to identify functional groups of hydrogel material shows that the existing functional groups of OH overlapping with NH at 3446.72 cm-1 from chitosan, C=O at 1633.49 cm-1 from glutaraldehyde, and C=N 1433.11 cm1 from polyacrylamide. In addition, morphologically has been identified by Scanning Electron Microscope (SEM) that the chitosan co-polyacrylamide hydrogel crosslinked by glutaraldehyde which is pores formed for passing water absorption. Based on this study, we can be able to utilize in regeneration of soil mining area.
