“…Young plantation trees, such as a great proportion of juvenile wood with relatively small dimensions and uncertain wood properties, are characterised as having an inferior wood quality (Kojima et al 2009;Ozarska 2009). By utilising these trees to manufacture high-value products, these characteristics require technically sophisticated facilities and advanced technologies (Ozarska 1998).…”

A Proposed Method and Its Development for Wood Recovery Assessment in the Furniture Manufacturing Process

A proposed method for assessing wood recovery involves application of a machining station approach with volume and mass measurements. A medium wood furniture company located in Jepara, Indonesia was selected to develop the method. Batch measurements of the inputs and outputs for different types of indoor-furniture products at every station were collected and analysed. For the volume method, three dimensions were measured on each specimen: the length, width, and thickness. For the mass method, the specimens were weighed before and after each processing station using a balance. Based on the mass method, the average total wood recovery rate was 26.2% ± 2.3%. For individual products and per station, the significant difference in the wood recovery rate occurred only at the resawing and edging, and trimming stations. The relationship between the teak quality, product dimensions, and type of finish was significantly different, where A-quality teak, large dimensions, and polyurethane finish resulted in a higher wood recovery rate. Both methods were reliable because of insignificant differences in the wood recovery rates. However, the mass method was more efficient and practical. The proposed protocol using the mass method is a suitable and effective system because the contribution of the variance component of the method was 2.71%.

“…It has been reported that xylem maturation depends on the diameter growth in tropical fast-growing tree species, such as A. mangium, F. moluccana, and others (Honjo et al 2005, Kojima et al 2009a, Makino et al 2012, Nugroho et al 2012. On the other hand, xylem maturation depends on cambial age in some tropical species that are not considered to be fast-growing species, such as Shorea acuminatissima and Tectona grandis (Ishiguri et al 2012b.…”

“…The wood properties of these species have been investigated by many researchers (Wahyudi et al 1999, Honjo et al 2005, Ishiguri et al 2007, 2012a, Kojima et al 2009a, b, Makino et al 2012, Nugroho et al 2012, Darmawan et al 2013).

“…In the case of softwood species grown in the temperate zone, tracheid length and microfibril angle which are closely related to the physical and mechanical properties of wood, become stable after the 15th to the 20th annual ring from the pith, suggesting that xylem maturation in temperate softwood species depends on cambial age (Watanabe et al 1963). Several researchers have investigated the xylem maturation process in tropical hardwood species (Honjo et al 2005, Kojima et al 2009a, Ishiguri et al 2012b, Nugroho et al 2012, Makino et al 2012). Researches have shown that the maturation process in some fast-growing species, such as Acacia mangium, A. auriculiformis, and Falcataria moluccana, depends on the diameter growth (Honjo et al 2005, Kojima et al 2009a, Makino et al 2012, Nugroho et al 2012.…”

The growth characteristics, anatomical characteristics, and wood properties of Dysoxylum mollissimum, a fastgrowing tree species, were investigated. To clarify the effect of radial growth rate on these characteristics and properties, 10-yearold trees planted in Bengkulu, Indonesia were examined and classified into three categories (fast-, medium-, and slow-growing). Xylem maturation type was also evaluated in this species. The mean values of stem diameter, tree height, stem volume, and stresswave velocity in the 50 measured trees were 18.0 cm, 10.6 m, 0.119 m 3 , and 3.48 km s 1 , respectively. Mean values of anatomical characteristics and wood properties in nine selected trees were as follows: vessel diameter, 129 µm; vessel frequency, 3.5 vessels mm 2 ; cell wall thickness of wood fiber, 1.2 µm; percentages of vessels, wood fiber, ray parenchyma, axial parenchyma, and cell wall, 8.8, 72.9, 12.4, 5.9, and 33.5%, respectively; vessel element length, 0.36 mm; wood fiber length, 1.04 mm; basic density, 0.45 g cm 3 ; and compressive strength parallel to the grain in green condition, 29.9 MPa. These obtained values were similar to or smaller than previous results obtained in research on other Dysoxylum spp. For almost all of the anatomical characteristics and wood properties, no significant differences among the categories were found. This suggests that the trees with faster radial growth characteristics do not always produce lower quality wood in this species. Judging from the radial variation of anatomical characteristics, the xylem maturation of this species depends on the diameter growth, and it might occur at around 6 to 8 cm from the pith.

“…En latifoliadas de porosidad difusa, la variación entre árboles, resultante de causas genéticas y medioambientales, es considerada por algunos autores como la mayor fuente de variación en la densidad, en tanto que la variación dentro del árbol relacionada con las diferentes edades formativas del leño lo es para la morfología de las fibras. Así lo expresan Downes et al (1997) en su revisión sobre modelos o patrones de diferentes propiedades del leño en el género Eucalyptus y sus fuentes de variación; y Kojima et al (2009) en su revisión sobre los modelos de maduración de fibras en latifoliadas de rápido crecimiento.…”
