The study synthesized geopolymer apron cassava starch/BC/Fe3O4/glycerin with different amounts of Fe3O4, and used quantitative analysis through FTIR to determine optical properties and attenuation constants. It was found that increasing Fe3O4 content could enhance the absorption and mechanical properties of the composite material.
Geopolymer apron cassava starch/BC/Fe3O4/glycerin has been synthesized for various amount of Fe3O4 (0.5%, 1%, and 1.5%) into cassava starch and black carbon (BC) solutions. The quantitative analysis from Fourier transforms infra-red (FTIR) was used to determine the optical properties, dielectric function, energy loss function, attenuation constant, and propagation constant. The higher value of the distance between two optical ((LOTO)) phonon vibration, attenuation constant, propagation constant was strong correlation with higher absorption properties and higher mechanical properties. The effectiveness of radiation shielding also from the density, linear attenuation coefficient (ii), mass attenuation coefficient (us), half value layer (HVL), and mean free path (MFP) from gamma radiation source IBT 103 Cs 137. The attenuation was 0.178 cm(-1), sample density was 0.984 g/cm(3), HVL value was 3.893 cm, and MPF was 5.618 cm. The best characteristic in supporting composite performance as an apron applications are for 1.5% Fe3O4 in the composite. This study shows that the FTIR spectra could be useful for determining the optical properties, phonon vibration, dielectric function, energy loss function, attenuation constant, and propagation constant of composite apron cassava starch/BC/Fe3O4/glycerin.
