Pembuatan dan Uji Karakterisasi Papan Komposit Berbasis Serat Kulit Jagung - Serat Eceng Gondok dan Serbuk Gergaji Kayu Menggunakan Resin Epoxy

Abstract

Composite board has been made with corn husk fiber, water hyacinth fiber and wood sawdust with epoxy resin as an adhesive. The composition of each fiber was varied and physical tests (density, porosity, water absorption and thickness expansion) and mechanical tests (MOE, MOR and compressive strength) were carried out, and microstructure was analyzed using SEM-EDX. The results of testing the physical and mechanical properties with optimum results were density of 1.03 gr/cm3, porosity of 10.48%, water absorption capacity of 10.22%, thickness expansion of 2.91%, MOR 256.05 kgf/cm2, MOE 228 kgf/cm2, and compressive strength of 3.19 MPa and obtained SEM-EDX test results on samples where pores were visible at 1000x magnification and increasingly clear at 10,000x magnification. The results showed that the physical (porosity, absorption and thickness expansion) and mechanical (MOR and compressive strength) tests met the standards of SNI 03-2105-2006, while the MOE test did not meet the standards. For density testing, it complies with SNI 01-4449-2006 standards. The composite board can be used as a substitute for wood for furniture materials.
