Abstract

Nowdays, there is growing interested in development of afrika wood utilization. Afrika wood is one fast growing species from plantation forest. The objective of this research was to evaluated of characterization of afrika fiber for pulp and paper production. Anatomical properties of afrika wood were also investigated. Determination of characterization of fiber dimension was conducted based on Tappi (1989). The resulted showed that afrika wood have type of porous namely soliter and radial multiple porous. The parenchyma and ray characters were paratracheal parenchyma confluent and multiseriate types. For fiber characteristic obtained by fiber length, fiber diameter, lumen diameter, and cell wall thickness were 935.33 µm, 28.52 µm, 21.29 µm, and 3.62 µm respectively. The derived value of afrika fibers obtained by runkel ratio, felting power, muhlsteph ratio, coefficient of rigidity, flexibility ratio, and fiber length were 0.43, 35.02, 20.51, 0.12, 0.76, and 935.33 µm respectively. Based on the derived value of afrika fibers, it qualifies as Grade II material for pulp and paper production. Afrika wood can be used as raw material for pulp and paper production.

Abstract

The yakisugi is a japan method on wood finishing that enhances an esthetic, dimension stability and durability. Yakisugi methode traditionally carried out by tying three boards together to form an elongated triangle and then burning until black charcoal is evenly created on the wood surface. Thes method has not been extensively researched or industrialized in Indonesia. Therefore, this study aims to evaluate the quality of yakisugi finishing on pine wood with parameters such as the length of the burning process (20 seconds and 30 seconds on a 70 cm2 area). The results showed that the pine wood burning process produced higher dimensional stability than pine without burning treatment, with ASE values reaching about 56% at a burning time of 30''.  Meanwhile, in the mechanical properties test, the yakisugi method provides lower values of MOE and MOR than the control sample—the change in wood properties to become more brittle after combustion is the main reason for this phenomenon. The combustion characteristics show that the combustion duration does not give a different color change in the test sample after the charcoal cleaning process. However, the thickness of the charcoal produced at 30" showed a higher value of 4.5 mm.
