Abstract

This research was on the synthesis of cellulose composites from camphor wood sawdust with LDPE waste (cellulose-LDPE) and Fenton reagent (H₂O₂/Fe²⁺) as the coupling agent. This study was divided into three steps: preparation, variation of LDPE composition and H₂O₂ concentration, and characterization. Preparation was done with cellulose extraction of sawdust and LDPE plastic waste purification. Variation was performed to determine the effect of compositions of LDPE on composites celullose-LDPE and H₂O₂ concentration on Fenton reagent. Characterization was done by testing the physical properties and functional groups using FTIR analysis. The best values of the physical property were obtained from cellulose-LDPE composition ratio of 1:5 on 1.5% H₂O₂. These were MOE (Modulus of Elasticity) of 12.71 MPa, MOR (Modulus of Rupture) of 200.24 MPa and density of 0.7936 g/cm. FTIR analysis showed the higher the composition of LDPE, the higher the wavenumber for OH and the increase of H₂O₂ concentration increased the C-H wavenumber functional groups.
