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.

Abstract

Formaldehyde emission and physical-mechanical properties of particleboard bonded with urea formaldehyde (UF) could have negative effects on human health, specially when used in a room with limited ventilation. To reduce formaldehyde emission, an adsorbent can be added into adhesive mixture. This report describes the effect of imposing active charcoal into urea formaldehyde adhesive in terms of formaldehyde emission, physical-mechanical changes and economic aspect of the recycled particleboard. Results showed that the addition of active charcoal in particleboard production significantly changed the product properties. The charcoal addition as much as 3% to the UF adhesive could reduce formaldehyde emission and improve physical-mechanical properties of particleboard, and meet the Indonesian and Japanese Standards. The addition of active charcoal into particleboard is financially feasible.

Abstract

Natural durability is determined through the tests of wood against wood attacking organisms. Natural durability of wood against marine borer was tested by exposing wood into the open sea water for six months. Damage intensity can be measured on the basis of digital image using Image-J software. This paper studies natural durability of nine wood species from Sumatera, Java and Kalimantan against marine borer. Results show that sempur lilin (Dillenia obovata Hoogl.), bambang lanang (Michelia champaca L.var. pubinervia) and kayu babang (Azadirachta excelsa (Jack) Jacobs) were classified into class durability I (very resistant), while cangcaratan (Lithocarpus sundaicus (Blume) Rehd. and avengekalakai (Shorea pervustipulata ssp. albifolia) were classified into class durability II (resistant) against marine borer. Ki pasang (Prunus javanica Miq.) and segelam (Hopea rudiformis) were grouped into class durability III (moderately resistant), while ki biwang (Arthophylum diversifolium Blume) and ki langir (Otophora spectabilis Blume) fall into class durability V (perishable). Damage intensity could be measured accurately using Image-J software. However, this method obtained higher damage percentage since the ex-rope hole was included in the measurement. Accordingly, the image method should be modified by excluding the ex-rope image to achieve high accuracy measurement.

Abstract

Tree length logging method is an alternative way in timber harvesting to improve the efficiency of timber utilization and preservation of forests resources. This paper studies the performance of tree length logging application method in operational scale. Observation was conducted in the forest area of PT Sarimelati Parakanca Timber in East Kotawaringin Regency, Central Kalimantan Province, where Intensive Silvicultural Technique (SILIN) was applied. Data were collected through observation and direct measurements in the field including labor productivity and cost of felling and skidding, logging waste, exploitation factor (FE) and the damage of residual stand. Results show both felling productivities and skidding were improved. The felling capacity was improved into 60.535 m³/hour and skidding was improved into 31.931 m³/hour. The application of tree length logging can also reduce the felling cost into Rp 1,604.36/m³ and skidding cost into Rp 21,142.75/m³. The method also increase the exploitation factors (FE) into 0.93 and minimize the damage on residual stand by 20.70%.

Abstract

Bamboo eschibits changes of its attractive green-colored skin inta ivory yellow. Bamboo colour wall turn into dark grey when immersed in water or kept in damp place. Consequently, an attempt is required to prevent such color changes on the surface of bamben skin. This remarch looks into the effectiveness of copper sulfate and nickel nitrate mixture in water based solution to maintain the green color on the skin surface of hambos (Gigantochloa apus Kurtz). The solution is employed in various proportions (w/w) and concentrations. Color innrpretation on the bamboo-skin surface wat assisted wting the so-called CDX's enfor difference meter device based on three-dimensional CIE (L*a*,*) principle. It turned out that intensity of green color on the skin of bamboo trunk at its top (upper) portion and middle portion was greaterthan that of the butt (lower) portion. Furfber, the use of copper culfate nickel nitrate miscture mlution at 4.0:3.5 proportion and in 7.5% concentration inflicted the greatest intensity of green color (", ", and be in average consecutively 61.8, -14.3, and 18.3) on the bamboo-skin, and concurrently afforded the inat prevention of such green color.
