Abstract

Plantation forests is generally harvested at the age of less than 10 years, thus the log is in small diameter, inferior physicalmechanical properties, and susceptible to bio-deterioration. The application of glued-laminated timber (glulam) could overcome theseissues and increase its utilization. This paper reviews the utilization of wood from plantation forest for glulam. Currently, woodfrom plantations forest studied in glulam research were jabon (Anthocephalus cadamba), rubber-wood (Hevea brasiliensis),mahogany (Swietenia sp.), mangium (Acacia mangium), manii (Maesopsis eminii), mindi (Melia azedarach), pine(Pinus merkusii), sengon (Falcataria moluccana), and sungkai (Peronema canescens). Kempas wood (Koompassiamalaccensis) and merbau (Intsia sp.) from natural forests were used as a layer combination of the glulam. The adhesives usedfor manufacturing glulam were tannin-based adhesives from mangium, mahogany, and merbau, as well as synthetic adhesives,namely isocyanate and phenol resorcinol formaldehyde (PRF). The results shows that glulam bonded with tannin-based adhesivehas physical-mechanical properties comparable with those of solid wood and glulam adhered with PRF adhesive. The physicalmechanical properties of glulam glued with isocyanate were similar with its solid wood. However, the shear strength of glulam waslower than solid wood. There was no delamination occurred in both cold and boiling water delamination tests. Thus, it fulfilledJAS 1152- 2007. The polystyrene impregnation applied in sengon and mindi glulams manufacturing resulted in a few effect ofcolor change, comparable shear strength to its solid wood, and increases its resistance to subterranean termites (Coptotermescurvignathus Holmgren) attack.

Abstract

Beside for its high natural durability and resistancy of weather properties, teak (Tectona grandis) wood is also valued for its beautiful grain and colour. Theoretically, wood colour is highly affected by extractive content, particularly in the heartwood. Identification of correlation between wood colour and extractive content was determined through wood colour and extractive measurements on the outer part of heartwood zone. The wood samples were collected from two locations of Perum Perhutani forest plantations, i.e. KPH Randublatung (35 trees, age class III-IV) and KPH Purwakarta (32 trees, age class VI). Samples were cut from bottom part of the trees and then ground into powder measuring of 40-60 mesh. The wood colour properties(CIE-L*a*b, CIE-L*C*h, CIE-X*Y*Z, Munsell Colour Chart and ISO Brightness) were then measured. Solubility of the teak wood extractives were determined by extracting the powder in ethanol-benzene and hot water respectively. Results showed that the range of colour properties were L*= 40-62; a* = 3-11; b* = 19-31; C* = 20-31; h = 70-82; X= 10-25; Y= 8-23; Z=4-13; H=5-8; V =3-8; C =3-6; and W (ISO Brightness) = 4-12. Different sample location resulted in different trends of correlation between colour properties and extractive contents. No significant correlation was found between extractive solubles in hot water and colour parameters. In general, the best correlations were encountered between brightness parameters from CIE-L*a*b* or ISO with ethanolbenzene extractive contents (r=- 0.54 or 0.50, respectively).

Abstract

Timber harvesting is an important process in timber utilization because it determines the quality of log. Two important things in timber harvesting are recovery rate and residual factors. This paper identifies distribution, forms and condition of harvesting waste as well as determines utilization factors and timber residual factor due to timber harvesting. Research was conducted in two areas of forest management in Wasior and Nabire Districts, West Papua Province. Recovery rate of forest concession with Reduced Impact Logging (RIL) techniques tend to be higher than that of conventional techniques. Recovery rate ranged from 86.3–87.8% with an average of 86.9% and residual factor ranged from 12.3–13.8%, with the average of 13.1%. The average utilized wood amounted of 4.578 m3/tree from the potential clear bole of 5.293 m3/tree. The wasted volumes ranged from 0.548 to 0.664 m3/tree with an average of 0.564 m3/tree. In general, most of the logging waste was in the form of wood defects (65.1%), broken (23.3%) and firm timber waste (11.6%) which represented the lowest percentage.

Abstract

Ear mushroom is one of edible wood rotting fungi that has been already consumed by community. Mushroom's media was made of sengon (Falcataria mollucana (1) Nielsen) sawdust with addition of 12 or 16% rice bran, 3.2% lime, 0.4% gypsum, urea or trisodiumphosphate 0.4% and water, then being composted for 1, 3, 5 and 7 days. Media samples were grouped into A and B, where sterilized media A were inoculated with brown ear mushrooms (Auricularia auriculae-judae HHBI-312, HHBI-326) and black ear mushrooms (Auricularia polytricha HHBI-318, HHBI-331), and those of media B were inoculated by black ear mushrooms (Auricularia polytricha HHBI-331). Biological Conversion Efficiency (BE) was calculated based on the ratio of the mushroom yield in fresh condition to the dry weight. Results indicated that the high yield of ear mushroom was obtained on composting media for 3 and 5 days periods. The average yield of Auricularia auriculae-judae HHBI-312, HHBI-326 on media A were 58.88 grams dan 60.51 grams (EB 10.96% and 10.92%), and for Auricularia polytricha HHBI-318, HHBI-331) were 67.5 grams and 101 grams (EB 12.38% dan 18.56%), respectively. Urea addition on the media tend to increase the BE value of A auricula-judae. Houvrer, it found that the yield and BE value of A. polytricha on media consist of urea were higher than that on media consist of trisodiumphosphate. The productivity of A. polytricha HHBI-331 on B-media added with 16% ricebran (102.06 g. BE 18.73%) revealed bigber than that which added with 12% ricebran (79.94 g. BE 17.59%). Therefore, A. auricula-judae HHBI-312 and A. polytricha HHBI-331 selected for further mushroom production.

Abstract

Wood machining is one of important utilization properties, especially for lesser known wood species. This paper determines the machining properties and possible utilization of punak (Tetramerista glabra Miq.), meranti bunga (Shorea teysmanniana Dryer ex Brandis), mempisang (Alphonsea spp.), suntai (Palaquium burckii H.J.L.), and pasak linggo (Aglaia argentea Blume) originated from Riau Province. The tests were conducted based on the modified testing standard of ASTM D-1666-64. Twenty samples of each species were machining tested for the work of planing, shaping, boring, turning, and sanding. Visual observation was performed using loupe 10x magnification. Research revealed that planing, shaping, boring, turning and sanding properties were significantly influenced by wood species. Punak and pasak linggo had good and very good machining properties. Mempisang had a wide range machining properties from poor to very good, while meranti bunga had poor to good machining properties. Lastly, suntai had a moderate to good machining properties. Regression analysis showed that higher specific gravity resulted in better machining properties. Wood with good to very good categories could be suggested as raw materials for various products. Mempisang and meranti bunga should be carefully handled, particularly in boring and turning processes.

Abstract

Dragon's blood is essentially a red-colored resin secreted by the fruits of rattan species. The dragon's blood originated from Indonesia which becomes widespread in international market is indigenous from Daemonorops spp. The dragon's blood has been popularly used as traditional medicines. To confirm such dragon's blood efficacy, an assesment was already conducted regarding the phytochemical screening, antioxidant activity, and anticoagulant activity indicatively afforded by the dragon's blood resin produced by three rattan species, ie. Daemonorops longipes Mart, Daemonorops draco BL, and Daemonorops melanochaetes BL. Phytochemical screening aimed to identify the kinds of chemical compounds inside the dragon's blood resin; antiæcidant tests used DPPH (2,2-diphenyl-1-picrylhydrazyl); and anticoagulation tests proceed in-vitro using rabbit blood. Results revealed that the dragon's blood from those three species, exctracted using polar (methanol) and semi-polar (ethyl acetate) solvents, contained chemical compounds which are already renowed for medicinal efficacy and potent antinccidant, e.g. flavonoids, triterpenoids, and tannin. The greatest antioccidant potency was imparted by dragon's blood from Daemonorops longipes Mart, as indicated by its lowest IC value (71.89U+3,89 mgl.). The ethyl acetate dragon's blood extract, rather than promoting anticoagulat action on the rabbit-blood, in fact induced the blood coagulation, whereby the extract from Daemonorops longipes Mart performed the most effectively (shortest in coagulation time).

Abstract

Jati Utama Nusantara (JUN) is one type of growing regime of fast grown teak (Tectona grandis Linn. F) derivedfrom Jati Plus Perhutani (JPP). JUN trees have fewer branches and a more cylindrical-shaped trunk, as well asexhibit rapid growth compared to the teak cultivated from seed (conventional); accordingly, they can beharvested in a shorter time. Despite its fast growth, some studies showed that the wood had not met the SNI01-0608 standard as raw material for furniture. The research aimed to improve several physical and mechanicalproperties of young JUN wood through thermal compression treatment. The test sample for 5-year-old JUNwood was prepared with a size of 2.5 cm (thickness/radial) by 10 cm (width/tangential) by 30 cm(length/longitudinal), then compressed using a 25 kg/cm2-pressure for 40 minutes in three temperaturetreatments of 170°C, 180°C, and 190°C. Testing of wood mechanical and physical properties referred to ASTMD143. The wood crystallinity was observed using an X-Ray Diffractometer (XRD), and the wood surface wasobserved visually. Wood cell structure as supporting data was observed using a stereo-capable microscope(Zeiss). The results revealed that the thermal compression could improve the physical and mechanicalproperties of the densified JUN samples compared to the nonthermally compressed samples. Based on datasimulation, the wood samples' best physical and mechanical properties occurred at approximately 185°C's heatpress.
