“…It can be seen that the highest elastic modulus value is owned by sawdust reinforced composites with a volume fraction of 25% by 5.09 GPa, and the lowest MOE was owned by wood chips reinforced composites with a 50% volume fraction of 0.29 Gpa. The MOE of pure teak wood is 1.08 GPa [10]. The results of data processing can also be seen trends that are owned by the comparison graph between the modulus of elasticity and also the volume fraction of the natural fiber composite of teakpolyester.…”

Kalimantan has abundant natural resources, including wood. The physical properties of wood have varying strength and flexibility and could replace concrete reinforcement steel. In this study, the mechanical properties and sound insulation of one of Kalimantan's natural fiber combined with polyester matrix were investigated. Natural fibers used were teak wood (Tectona Grandis) with sawdust and wood chips. Specimens were made using the hand lay-up method with a wood volume fraction variable of 25%, 35%, and 50%. Afterward, the bending, morphology, and sound insulation tests were carried out. In this study, it can be concluded that the higher wood volume fraction used, the higher the ability of sound insulation. Conversely, it reduces the modulus of elasticity. Besides, the form of sawdust fillers has a better ability than wood chip fillers in terms of sound insulation and the modulus of elasticity.

“…The results of measurements on physical and mechanical properties were shown on Table 1. [16], the MOE and MOR values of the synthetic wood are higher than those of both Teak timbers varieties, however the compressive strength parralel to grain of the synthetic wood is lower than that of both Teak timber varieties. It means that the mechanical properties of synthetic wood is in between of Merbau and Teak timbers.…”

Abstract-Our finding on a technology for producing woodcrafts using nanocomposite reinforced synthetic wood becomes an alternative solution for solving the current problems of Balinese woodcraft industries. The study on applying the current developed synthethic wood technology was conducted in order to analyze the production cost comparing toward the cost using natural wood, to gain the market responses for analyzing the comsumer satisfaction and the market competitive prices and to gain the stakeholders for innitiating a cluster industry. The costumer satisfaction as well as stakeholder acceptibility on the synthetic wood technology could revitalize the Balinese woodcraft industries.

“…In this case, specific gravity was more dominantly affected by growing sites than clone types. Specific gravity of D14 clone was higher than Mega teak aged 11 years (0.50) and almost the same as conventional 14-year old teak which produced a specific gravity of 0.55 (Hidayati et al 2016). Figure 5 shows the variability of green specific gravity in the radial direction of JUN teak trees at the age of five and eight years.…”

Abstract. Putro GS, Marsoem SN, Sulistyo J, Hardiwinoto S. 2020. The growth of three teak (Tectona grandis) clones and its effect on wood properties. Biodiversitas 21: 2814-2820. Various clones of superior teak (Tectona grandis L. f.) trees have recently been introduced in several land conditions. A study was conducted on three different clones of superior teak known as Jati Unggul Nusantara (JUN) growing in Paliyan, Gunungkidul, Yogyakarta, Indonesia. Two different ages of those clones were observed their growth rate and its wood properties. Strip plot design was applied to the treatment of tree age (five and eight-year-old) and clone types (D14, F35, and F21 clones). Tree growth was measured on 300 trees, meanwhile, annual growth rate and wood properties were measured on 18 trees. The result showed that at five-year-old as well as eight-year-old, the D14 clone has the best growth performance with diameter of 14.6 ± 1.80 cm and 20.5 ± 2.54 cm and height of 9.8 ± 1.72 m and 15.2 ± 2.13 m respectively. The growth rate negatively correlated with temperature and had no significant correlation to the precipitation. Different clones and tree age significantly affect the variability of fiber length, green specific gravity, and heartwood proportion. The clone of D14 produced the highest-fiber length, green specific gravity, and heartwood proportion (1.111mm; 0.50 and17.7%) at five-year-old trees and (1.156 mm; 0.54 and 49.0%) at eight-years-old.
