Abstract

The quality of the cement board depends on the compatibility between cement and particles fromlignocellulosic biomass. The purpose of this study was to determine the compatibility between cementand particles from four tropical wood namely mangium (Acacia mangium Willd), teak (Tectona grandisLinn. F.), gelam (Melaleuca leucadendron (L.), dadap (Erythrina variegata L.), and sago stem (Metroxylonsago Rottb.), and to determine the physical and mechanical properties of the mangium cement boardproduced by adding magnesium chloride (MgCl2) as an accelerator. This research was conducted intwo steps. The first step consisted of measuring the hydration temperature of a mixture of cement with particles from the four wood species and sago stems by adding magnesium chloride (MgCl2),with variations of 0%, 2.5%, 5%, and 7.5% based on the cement weight. Two types of mixturesfrom the first step were then used in the second step, namely the manufacture of cement board. The cement board was made using a weight ratio of mangium particles:cement:water of 1:2.7:1.35. Theboard is made with a target density of 1.2 g/cm3. Physical and mechanical testing refers to the ISO8335-1987 standard. The results of the hydration temperature showed that all of the mixtures wereclassified into “low inhibition”, except for mixture between cement and mangium particles without a catalyst which was included in the classification of “moderate inhibition”. While the results of cement board tests indicate that the cement boards made from mangium wood particles with 5%MgCl2addition had better properties compared to mangium cement boards without catalysts.

Abstract

Laboratory-scale manufactured hardboard made of Saccharum Sponaneoun Grasses (SSG), Empty Oil-palm Bunches (EOPB), and andong bamboo is potentially developed. However, initial experiment shows the hardboard did not meet Japanese Industrial Standard (JIS) and International Standard Organization (ISO) for hardboard. This paper observes modification of the hardboard to satisfy the standards. Modification includes adding alkali concentration during pulp cooking and changing the additives composition. Result shows modification can enhance the hardboard quality to satisfy JIS and ISO requirements. Fiber mixture of SSG pulp and andong/betung bamboo pulp was cooked in 10.5% alkali concentration; and 12% alkali concentration for EOPB pulp. Additives composition used were tannin-resorcinol formaldehyde/TRF adhesive, alum, and activated charcoal; without wax emulsion. The mixture of SSG pulp (50%) + EOPB pulp (50%) was the most prospective for hardboard, followed by SSG pulp (100%) solely; SSG pulp (50%) + andong bamboo pulp (50%); and SSG pulp (50%) + betung bamboo pulp (50%) as the lowest prospects. The least prospective fibrous material (betung bamboo) are expectedly be improved by using more TRF adhesive, nano-size activated charcoal and cross-linking agents.

Abstract

The science advancement in this century is such that in the future it will enter the nano technology. More specifically in the forest products field, the nano technology that can be developed is among others nano carbon derived from lignocelulosic stuffs. In relevant, this research aims to provide information and technology on the charcoal processing from lignocellulosic stuffs into nano carbon. The lignocellulosic stuffs used in this research consisted of teak wood and bamboo, further carbonized into charcoal at 400-500°C using drum kiln. The resulting charcoal was examined of its physical and chemical properties, crystalinity degree and dielectric characteristics, and then purified by re-carbonizing it at 800°C for 60 minutes. Prior to the purification, the charcoal sustained the doping (intercalation) process with Zn, Ni and Cu metals each respectively. After the purification, the charcoal was ground to very tiny particels using HEM (high energy machine) device for 48 bours. In this way, the charcoal with high crystalinity was yielded, and further sintered using spark plasma at 1,300 C into the nano carbon. The qualities and structure of all the resulting carbon (carbonized charcoal, re-carbonized charcoal, intercalated charcoal and sintered nano carbon) were evaluated using nano scale device (Py-GCMS, SEM-EDX and XRD), and examined as well of their dielectric characteristics. In turns out that the best quality charcoal was obtained from teak wood charcoal carbonized at 800°C, intercalated with Ni atoms at the ratio 1:5. The resulting charcoal afforded high crystalinity (78.98%), low electric resistance (0.17 2), and high conductivity 175.52 2'm Qualities of the corresponding nano carbon (after sintering) were such that its crystalinity spectaculary reached 81.87%, resistance (R) 0.01 & with very bigh conductivity 1067.262'm'. The nano carbon that resulted seems favorably prospective for bio-censor, bio-battery, and bio-electrode. Accordingly futher related research deserves carrying out.

Abstract

This paper presents to the resin content and the chemical composition in agarwood with several quality using gas chromatography mass spectrometry. The agarwood qualities as tested were those super and kemedangan classes originated from Bangka, Papua and Assosiation of Indosnesia's Agarwood Exportry Enterprise (Asgarin). Results revealed the resin yield of super quality agarwood was higher than that of kemedangan-quality counterpart. Agarwood with high resin content was regarded a high (super) quality, and its chemical composition was predominantly chromone and gamma gurjunene. On the contrary, agarwood with low quality (kemedangan) chemicallyy comprised 2.5 furandione, 3-dodecenyl and agarospirol. Further super-quality agarwood chemically contained more sesquiterpene than kemedangan-quality. Sesquiterpene and chromone compound were indicatively responsible the fragrant arome revealed by agarwood. The quality of agarwood in the same quality class but originated from different regions revealed the resin content as well as chemical composition which was different fromeach other.

Abstract

Polyphenol chemical components extracted from merbau (Intsia spp.) wood exhibit a strong affinity for resorcinol and formaldehyde in alkaline conditions, forming a copolymer that could serve as an adhesive. This paper studies the use of resorcinol adhesives from merbau wood extracts containing poly phenolics which copolymerize with formaldehyde bonding wood laminates. Results show that copolymer of merbau extracts with formaldehyde could produce resin with molecular weight 49,658. The resin can be used as adhesive for laminated board manufacturing of a 3 ply-1 strip flooring parquet constructed with 7 wood species, i.e: sungkai, karet, kempas, merbau, mangium, mahoni and sengon. Bonding quality and physical-mechanical properties of the products laminated meet the same product that glued using imported adhesive and included exterior quality with E₀ or F**** types of low emission formaldehyde.

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

The research aimed to look into the growth responses of sengon, jabon, and agarwood seedlings; and to examine the carbon (C), nitrogen (N), phosphor (P), and potash (K) contents in soil as well as in the biomass portions of those three plant species (i.e. their leaves, stems, and roots) after being added with charcoal and wood vinegar. It also intended to explore the potency of carbon store in such plant-biomass portions. The charcoal addition was conducted by mixing it with soil evenly and homogenously, while wood-vinegar incorporation proceeded by spraying it onto the soil. For taking care of the plants, the wood vinegar was sprayed periodically to their stems, twigs, and leaves. Results revealed that the growth of sengon seedlings achieved the greatest in height (156.33 cm) and in diameter (20.08 mm), attributed to the addition of wood vinegar (2%) and charcoal (10%). For jabon seedlings, the greatest growth in height (89.17 cm) and in diameter (19.22 mm) occurred due to addition of wood vinegar (4%) and charcoal (20%). For agarwood seedlings, the greatest growth height (72.20 cm) and in diameter (18.29 mm). Besides, the addition of charcoal and wood vinegar could not also bring about the increase in consecutively nutrient contents (e.g. C, N, P. and K), biomass weight, and carbon store, which varied in the leaves, stems, and roots, in accordance to the percentages/ dosages of those two agents as added.
