PEMANFAATAN LIMBAH KUL IT KAYU (Acacia mangium) SEBAGAI BAHAN BAKU PAPAN PARTIKEL MENGGUNAKAN PEREKAT DAMAR

Abstract

Acacia Mangium bark waste is an alternative form of raw material that can be used as a raw material in making particle board. Acacia Mangium skin has wood components ranging from 10.5 - 12.1%, while the adhesive used is resin 70% mixed with solar oil 30%. Making particle board with a size of 25 cm x 20 cm x 2 cm with a particle size of 4 mesc with boiling method of raw materials and drying, pressing for 8 hours and conditioning for 20 days. The purpose of this study was to determine the physical and mechanical properties of the particle board, using 3 samples and 3 replications for each test, the data obtained then averaged then the results compared with the characteristics of SNI 03-2105-2006. Based on the results of the research on physical properties, namely density 0.91 gr/cm3, moisture content 11.91%, water absorption 65.12% and development thickness of 16.39% while the mechanical properties are MOE 1.70 104 kgf/cm2 and MOR 27,62 kgf/cm2.
