PENGARUH JENIS PEREKAT DENGAN LAMA WAKTU PENGEMPAAN TERHADAP MUTU FISIK PAPAN LAMINA BERBAHAN POHON KAYU MANIS (Cinnamomum burmanii)

This study aimed to investigate the effect of adhesive type and pressing duration on the physical properties of laminated boards made from cinnamon wood (Cinnamomum burmanii), in an effort to enhance the utilization of non-timber forest residues into value-added products. The research was conducted over three months at the Forestry Faculty Workshop, Lambung Mangkurat University, using a factorial completely randomized design with two factors: adhesive type (Presto WRG and PVAc Rajawali) and pressing time (1×24 hours and 2×24 hours). The physical parameters tested included density, moisture content, thickness swelling, thickness shrinkage, and delamination. Results showed that PVAc Rajawali with 2×24 hours pressing yielded the highest density, whereas Presto WRG offered superior delamination resistance. Adhesive type and pressing time had no significant effect on moisture content, swelling, or shrinkage, which were largely influenced by the natural characteristics of cinnamon wood. Therefore, the appropriate combination of adhesive and pressing technique can enhance the feasibility of cinnamon wood as an efficient and sustainable material for laminated board production
