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.

“…The values of pellets density obtained in this work are similar to 1.12–1.3 g/cm 3 reported in The Pellets Handbook by Thek & Obernberger (2012) . Comparing wood density average, Rodriguez et al (2016) found that wood pellets density of A. wrightii , E. ebano and H. pallens increased 30%, 25% and 93%, respectively, which confirm that pelletization is a good process to increase the density even to denser species. The bulk density of the input material is an important factor in pelleting as the mills are fed by volume rather than weight ( Filbakk et al, 2011a ).…”

BackgroundThe need for energy sources with low greenhouse gas emissions and sustainable production encourages the search for alternative biomass sources. However, the use of biomass fuels faces the problem of storage, transport and lower energy densities. Low-density values can negatively affect energy density, leading to an increase in transportation and storage costs. Use of pellets as alternative biomass source is a way to reduce the volume of biomass by densification, which improves their energy quality. They are produced by diverse biomass resources and mainly from wood materials. In all cases, it is important to evaluate the fuel characteristics, to determine their suitability on the heating system and handling properties.MethodsThe present study determines and compares data from proximate analysis, calorific values, physical and mechanical properties of wood pellets produced from the common tropical species Acacia wrightii, Ebenopsis ebano and Havardia pallens. Data were obtained from pellets produced from each species chips collected from an experimental plantation and analyzed through ANOVA and Kruskal–Wallis test at 0.05 significance level.ResultsThe results of diameter, length and length/diameter ratio didn’t show statistical differences (p > 0.05) among species. Acacia wrightii showed the highest density (1.2 g/cm3). Values on weight retained and compression test showed statistical differences (p = 0.05) among species. Havardia pallens was more resistant to compression strength than A. wrightii and Ebenopsis ebano. Statistical differences (p < 0.01) were also observed for the volatile matter and calorific value. E. ebano has the lowest volatile matter (72%), highest calorific value (19.6 MJ/kg) as well as the fixed carbon (21%).DiscussionThe pellets of the species studied have a high energy density, which makes them suitable for both commercial and industrial heating applications.A pellet with low compression resistance tends to disintegrate easily, due to moisture adsorption. The percentages obtained for the resistance index were higher than 97.5%, showing that the pellets studied are high-quality biofuels. Proximate analysis values also indicate good combustion parameters. Pellets of Acacia wrightii and Ebenopsis ebano are the more favorable raw material sources for energy purposes because of their high density, calorific value, low ash content and they also met majority of the international quality parameters.

“…Besides that, the tearing strength and folding endurance of paper are indicated by the slenderness ratio [20]. Larger slenderness ratio results are better for paper making where it indicates a better formed and well-bonded paper [19,21]. Present results showed that the slenderness ratio of the four pioneer species is in the range of 36.4-50.2.…”

The purpose of this study is to evaluate the anatomical, physical, and mechanical properties of four pioneer species, i.e., batai (Paraserianthes moluccana), ludai (Sapium baccatum), mahang (Macaranga gigantea), and sesendok (Endospermum malaccense). Correlation of factors influencing density, shrinkage, and mechanical properties were also discussed. Samples were obtained from the Forest Research Institute Malaysia (FRIM) campus. From the result obtained, these four pioneer species characterised by medium-to-large vessel with absent of tyloses and gum deposit, fine ray, thin walled fibre, runkel ratio less than 1.0, low in density, and mechanical properties. Sesendok has significantly higher value in fibre length, fibre diameter, fibre lumen diameter, fibre wall thickness, vessel diameter, density, MOR, MOE, compression parallel to grain, and shear parallel to grain compared to the other three pioneer species which were 2001 µm, 45 µm, 35 µm, 5.1 µm, 300 µm, 514 kg/m 3 , 79.5 N/mm 2 , 9209 N/mm 2 , 38.7 N/mm 2 , and 10.1 N/mm 2 , respectively. Between these four pioneer species, ludai has significantly higher in runkel ratio which was 0.57, whereas mahang shows significantly higher in slenderness ratio and number of vessels/mm 2 which were 50.2 and 5 vessel/mm 2 , respectively. On the other hand, batai has higher tangential, radial and longitudinal shrinkage compared to ludai, mahang, and sesendok which were 3.0%, 2.4%, and 0.8%, respectively. Based on the basic property study, batai, ludai, mahang, and sesendok could be suitable for pulp and paper, plywood, light construction, furniture, interior finishing, and general utility. Fibre length, fibre wall thickness, and vessel diameter correlated significantly with density and mechanical properties. Shrinkage and mechanical properties were significantly influenced by density.
