Abstract

ABSTRACTIn order to increase plywood production in Indonesia, utilization the timbers coming from forest community is very important. Some species that widely planted at the forest community in DI Yogyakarta are akacia (Acacia auriculiformis) and sungkai (Peronema canescens). This research was aimed to know the combination some veneers formed of acacia timber and sungkai timber with the urea formaldehide resurfaced adhesive to producing the high quality plywood. The combination treatments were veneers from acacia timber (S1), veneer from sungkai timber (S2), veneer-core from acacia timber and veneer – face – back from sungkai timber (S3), and veneer-core from sungkai timber and veneer – face – back from akasia timber (S4). The experiment used complete randomized design with the further test using Tukey procedure in processing data. The research result showed that the treatment of veneer-core from acacia timber, and veneer-face-back from sungkai timber with the 60 #/MSGGL resurfaced adhesive have the better physical and mechanical property than the other treatments. Despitefully, sungkai timber has more decorative wood and a high commercial value.Keywords: Acacia, plywood, sungkai, veneer

Abstract

ABSTRACTMahang (Macaranga hypoleuca) is one of some lesser know species that widely grow at the secondary forest, especially in Central Kalimantan. This research was aimed to determine the properties of mahang timber quality and the relationship between axial and radial position concerning its properties. Research method using the factorial complete random design (CRD) 3 x 2. The first factor is the axial wood position (a) consist of the bottom (a1), the middle (a2), and the top (a3). The second factor is radial position (b) consist of axial (b1), and radial (b2). Data analysis using honestly significant difference (HSD). The wood’s water content test using ISO 3130 – 1975 (E) standart, the wood density test using ISO 3131 – 1975 (E) standart, and the wood shrinkage test using ISO/DIS 4469. The cell proportion test using grid mask method of Image Pro Plus V 4.5 program, whereas its dimension test using Image Pro Plus V 4.5 program. The wood extractive content test using ASTM D.2016-65, (ASTM D.1107-56), and (ASTM D.1110-56) procedures. Research result showed that wet vapor is 44.43%, dry vapor is 13.46%, specific gravity is 0.36, and the shrinkage TR ratio is 1.76. About fiber dimension: the fiber length is 1.6 mm, fiber diameter is 18.5µ, lumen diameter is 15.2 µ and thick of cell wall is 3.3 µ. The proportion of wood cell: spokes cell is 10.5%, parenkim is 11.3%, vessel cell is 16.5% and fiber is 62.1%. There is a relationship between several adhessiveness characteristics and wood quality toward the influences of the mahang wood’s actial and radial positions.Keywords: axial, Macaranga hypoleuca, radial, wood quality
