Kualitas Papan Zephyr Pelepah Sawit dan Papan Komposit Komersial Sebagai Bahan Bangunan
Abstract. Zephyr board can be made from oil palm petiole, the waste from oil palm plantation. The objective of this study was to compare the quality of palm petiole zephyr board (PPZB) and the quality of several types of commercial biocomposite boards (plywood, block board, and particle board) available in market based on their physicalmechanical properties. PPZB that was compared was the zephyr board made from 3 layers of zephyr strands arranged crossly with urea formaldehyde adhesive. The target density was 0.8 g cm⁻³, and the board size was 300 mm x 300 mm x 10 mm at a pressing temperature of 120 ⁰C, and a pressure of 25 kg cm⁻² for 10 minutes. The commercial composite boards were taken randomly from a hardware store. The results of the study showed that
3-layer PPZB, plywood, block board and particle board each had the density of 0.79 g cm⁻³, 0.81 g.cm⁻³, 0.40 g.cm⁻³ and 0.67 g.cm⁻³, respectively. The respective average value of MOE of each board was 617.6(x10² kg.cm⁻²), 728.47(x10² kg.cm⁻²), 398.74 (x10² kg.cm⁻²) and 199.22(x10² kg.cm⁻²), and that of MOR of each board was 405 kg cm⁻², 541 kg cm⁻², 207 kg cm⁻², and 119 kg cm⁻², while the screw holding strength of each was 88.49 kg, 92 kg, 53.6 kg and 61.4 kg, respectively.
