ABSTRACTBark waste of Acacia mangium could to produce the tannin formaldehyde adhesive that useful as material to the wood working industrial. These material are produced from timber estate of Acacia mangium that widely planted in Sumatera and Kalimantan, and also in the other place, because this species is the fast growing species and relatively easy to grow at the marginal site. Acacia mangium bark was predicted 10% of the logs. The study was aimed to determine the quantity of tannin formaldehyde from Acacia mangium bark that could be developed for the adhesive. The study showed that potency

Increasing the value of bark can be known through the characteristics of the bark such as physical properties, the grade of fiber quality and the chemical composition of the bark. The purpose of this study is to find out the characteristics of the bark of the acacia plant species (i.e. Acacia auriculiformis and Acacia mangium) of Industrial Plantation Forest. The characteristics of the bark observed includes physical properties, quality grade of fiber and chemical composition. The results of this study showed that the bark density, thickness and water content of A. auriculiformis were 1.18g/cm

This study aimed to investigate the ash content and concentrations of inorganic elements present in the stem of Acacia mangium. The tree samples (24 years) were collected from five different provenances (Sidei, West of Morehead, Daintree, Ellerbeck, and El Arish). Meanwhile, the disc samples were obtained from the trunk of each tree on the lower parts. The samples were collected from four radial positions (bark, sapwood, outer heartwood, inner heartwood), and the ash and insoluble acid contents were determined. Furthermore, the concentration of 5 elements (Ca, Mg, Fe, Mn, K, and Na) was measur

This study aimed to investigate and compare the qualitative and quantitative anatomical characteristics of Acacia mangium and Acacia hybrid in plantation forests in Vietnam. The qualitative and quantitative anatomical characteristics were evaluated according to the International Association of Wood Anatomists list of microscopic features for hardwood identification. In terms of qualitative features, A. mangium had a rough, hard, and fissured bark surface with a golden brown to dark brown color, whereas A. hybrid had a smooth and slightly scaly bark surface with greenish brown to greyish brown

Corrosion is a decrease in the quality of a metal material caused by a reaction with the environment. Corrosion cannot be eliminated, but corrosion can be slowed down in several ways by adding corrosion inhibitors and synergistic effects. Acacia bark extract (Acacia mangium Willd) with the addition of 0.02 M KI has the potential as a corrosion inhibitor for steel because it contains secondary metabolites, so it can provide a synergistic effect and increase the value of inhibition efficiency on steel. This research aimed to analyze the effect of a mixture of acacia bark extracts (Acacia mangium

Bark, especially from Acacia mangium is a by-product from wood processing industries that commonly found in Indonesiaand in big amount will cause environmental problems. One of the alternatives to utilize bark is for animal feed. The aims of this experiment are to improve the nutritive value of bark by alkali treatments (urea and sodium hydroxide) and to determine the level of substitution of elephant grass by bark. The experiment consisted of 3 in vitro studies and 1 in sacco study. In vitro studies consisted of 1) the use of urea or NaOH by wetting and incubation-method, 2) the use of differ

Abstract The purpose of this research was to create bio-based non-isocyanate polyurethane (Bio-NIPU) resins derived from the tannin of Acacia mangium Willd. bark for the impregnation of ramie fibres (Boehmeria nivea L.) and to investigate the properties of impregnated fibres. Tannin was extracted from the bark of A. mangium using hot water. Tannin-bio-NIPU resin was created using dimethyl carbonate and hexamine. Based on the findings, it is possible to conclude that tannin extract from the bark of Acacia mangium can be used effectively as a renewable alternative to toxic polyols in the develop

The purpose of this study was to develop practical and reliable small-angle x-ray scattering and x-ray diffraction methods to study the nanostructure of the wood cell wall and to use these methods to systematically study the nanostructure of Acacia mangium wood grown in Sabah, Malaysia. Methods to determine the microfibril angle (MFA) distribution, the crystallinity of wood, and the average size of cellulose crystallites were developed and these parameters were determined as a function of the tree age and the distance from pith towards the bark. The mean MFA in Acacia mangium increases rapidly

Yield prediction models were developed for plantations of Acacia mangium and Acacia auriculiformis raised under the Kerala Forestry Project in Southern Kerala, India based on the data gathered from temporary sample plots laid out in plantations in the region. The data consisted of girth at breast-height and total height of trees, collected from sample plots of size 20 m x 20 m. Yield prediction models were constructed using Schumaher functions. Height-diameter equations and site index curves were also developed along with the yield prediction models. The fitted equations had high coefficient o
