Abstract

This paper studies the physical and mechanical characteristics of the glued-laminated (glulam) beams made from small diameter of three fast growing species i.e. teak (Tectona grandis L.f), mangium (Acacia mangium Willd.) and trembesi/monkeypod (Samanea saman Merr.) using water based polymer isocyanate (WBPI) as a binder. Six plies of wood combination species were laminated into final dimension of 6 cm × 12 cm × 300 cm. Each laminate was graded using Machine Stress Grading (Pantek, plank sorter) to determine its Modulus of Elasticity (MOE). Cross-section of two type of glulam beam was 6 cm × 12 cm, arranged of various widths and based on values of laminate MOE. Results show that the average and range value of the glulam density were 0.658 g/cm³ and 0.557-0.821 g/cm³, with the moisture content of 14.6% (13-16.8%). The average of the glulam modulus of elasticity and modulus of rupture were 75.51 (37.016-120.446) kg/cm² and 494 (145-750) kg/cm² respectively. The glulam made from teak has better MOE and MOR performances compared to those of mangium and trembesi. In general, the results showed that almost all of glulam beams tested meet requirement of JAS (Japanese Agricultural Standard) 2007 for structural glulam in moisture content, MOE, MOR, and shear strength. The glulam qualities can be classified into E65-E95-F225-F270, except for several species combination beams. Based on the strength classified and the ratio of S/W, the glulam can be used as a construction material except glulam teak-trembesi (preserved or unpreserved) and the unpreserved trembesi-trembesi. The three types of glulam can be utilized for the lightweight construction.

Abstract

Combination of bamboo and wood composite beam is one possible laminated product to be developed. Generally, the composite product of solid wood meet the strength requirement for construction. However, composite beam combination of bamboo and wood has not been studied intensively. This paper observes the properties of composite combination of three bamboo species: andong, petung and ori with jabon wood species using isocyanate glue and merbau extracts. In order to improve composite’s durability, bamboo and jabon wood were preserved using 7% of boric acid and borax. Result shows composite beam combination of bamboo and jabon wood bonded with isocyanate is found to be the best composition in term of physical and mechanical properties. The density of the composite beam is 0.64 g/cm³ in 9.70% moisture content. Modulus of Elasticity (MOE) 78,168 kg/cm², Modulus of Rupture (MOR) 384 kg/cm² and compression parallel to the glue line is 378 kg/cm².

Abstract

This study aims to determine the resistance of 20 wood species against subterranean termites (Coptotermes curvignathus Holmgren) and dry wood termites (Cryptotermes cynocephalus Light). The test method of subterranean and dry wood termites refers to the SNI 01-7207-2006. Parameters observed for determining resistance class to subterranean and dry wood termites are the percentage of wood weight loss and the survival percentage of termites. Besides that, a subjective observation an severity of subterranean and dry wood termites attacks were also conducted. Results show that the resistance of 20 wood species against subterranean termites are as follow: class II (3 wood species), class III (2 wood species), class IV (13 wood species) and class V (2 wood species). The resistance to dry wood termites of the 20 wood studied species can be grouped as follow: class I (4 wood species), class II (5 wood species), class III (8 wood species) and classIV (3 wood species).

Abstract

Galam wood (Melaleuca leucadendra L.) is traditionally used for building materials, charcoal and fire wood. Currently, the tree bark remains unused, wasted or burned. The tree bark is potentially developed for particleboard manufacture. This paper studies the properties of particleboard made of galam tree bark. Galam bark pieces with dimension of 2 × 4 × 6 cm were bonded with Urea Formaldehyde (UF) in three different amounts: 11%, 13% and 15% of the total weight. The mixture was hydraulically pressed in 15 kg/cm² and temperatures of 110-120°C for 15 minutes prior to air dry. The physical and mechanical properties were tested according to the Indonesian National Standard 03-2105-2006. Results show that moisture content of the boards vary between 9.5 - 12.30% and the thickness swelling ranges between 2 - 11.35%. Boards density are about 0.68 - 0.77 g/cm³, Modulus of Elasticity (MOE) of 204.98 - 11210.91 kg/cm² and Modulus of Rupture ranges between 40.49 - 104.23 kg/cm². The screw withdrawal strengths are 44 - 84 kg and internal bond varies from 0.27 - 0.65 kg/cm². Based on the physical and mechanical properties, the particleboard made of galam tree bark mixed with 15% of UF meet the Indonesian National Standards 03-2105-2006.

Abstract

The previous research of bagasse utilization from the sugar plant's waste for making boards using Urea Formaldehide (UF) as an adhesive up to 10%, resulted particle's boards with inferior physical and mechanical characteristics which could not fulfill the Indonesian standard. This paper investigates an improvement effort by increasing portion of adhesive to 12% and 14%. Results indicated that the boards had better quality than the previous research. All aspects of the improved particle's boards could fulfill standard of Indonesia, Japan and FAO, except thickness swelling and MOE values which are below the standard. There have been a clear tendency that a higher level of adhesive exerted a better quality, although particle boards characteristic were not affected by adesive level,except modulus of elasticity.

Abstract

In Indonesia, logging in natural forests is generally undertaken by cutting the main trunk along the clear boles and skidding the trunk to the landing point. This paper examines skidding performance of an alternative method, i.e. tree length logging which conducted by cutting off the stem above the first branch up to minimum diameter of 20 cm, which is manifested by the productivity and skidding cost. The method was practiced in four areas of Licency Natural Forest Concessionary managed by intensive sylvicultural system. Results show that the log skidding productivity ranged from 21.127 – 23.893 m³/hour with average of 22.217m³/hour depending on skidding distance. Meanwhile, skidding cost of tree length method ranged from Rp 24,852.36 - Rp 29,318.49/m³ with average of Rp 28,628.10/m³ with skidding distance ranged from 100 m to 225 m.

Abstract

Activated carbon has been used widely for various applications. Hydro-char which is hydrothermally carbonized from biomass could be used as an alternative precursor for activated carbon manufacture, which is commonly obtained from pyrolized-char. This paper observes crystalline structure of Acacia mangium’s pyrolized-char and hydro-char using XRD (X-raydiffraction). The mangium wood was carbonized in 200°C and 300°C and depth analysis was conducted based on activated carbon product. Result shows carbon maturity index and aromaticity from both precursors (conventional and alternative) tends to increase after being activated; interlayer spacing (d002) is getting closer; meanwhile, crystallinity is greater; and the number, height as well as width of aromatic layers are increasing. Hydro-char exhibited crystallinity degree, maturity and aromaticity lower than those of the pyrolized-char obtained at 300°C carbonization, with the greater volatile content. Both types of char perform carbon structure with amorphous texture. The greatest iodine adsorption is achieved by hydro-char which was carbonized at 300°C. In general, XRD analysis on low temperature carbonization of pyrolized-char and hydro-char could predict the porosity of activated carbon.
