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.

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.

Rattan in Indonesia is traditionally utilized for furniture, binding materials, household appliances, and handicraft items. Small diameter rattans are commonly used by craftsmen, while large diameter rattans are not optimally utilized. Large diameter rattan, however, has potential to be developed into rattan laminated board (RLB) by gluing rattan strips using appropriate adhesive. Nevertheless, the information of the suitable natural adhesive for RLB production is still limited. Laboratory scale of RLBs with the dimensions of 60 cm x 7.5 cm x 1.5 cm were manufactured using batang rattan strips

Abstract Fixation is a stage in dyeing fabric or batik fabric with natural dyes to obtain the desired color and bind the color so that it does not fade quickly due to sweat, washing, sunray, and rubbing. Three fixators used as color binders were alum (Al2[SO4]3), lime (CaCO3), and tunjung (FeSO4). Each material showed a different color on each extract. This activity aimed to observe the color performance of bark extracts from three wetland species applied to batik fabric with 1 or 2 combinations of fixators. The results showed the color performance of batik fabric depended on the bark of tree

In May 2010, canker and wood stain symptoms in trunks and stems of 125 Acacia mangium were observed during a survey conducted in the Uverito plantations, Monagas State, Venezuela. Cankers were 20 to 65 cm long and were brownish on the margins and dark brown in the center. Many of the cankers had swollen margins and in some cases a black exudate could be seen leaking from the most severe cankers. Small pieces (4 to 5 mm) of necrotic tissues from the cankers were surface sterilized for 1 min in 1.5% NaOCl, washed twice with sterile distilled water, and plated onto potato dextrose agar amended wi

Acacia mangium is a widely grown tree species across the forests in Brunei Darussalam, posing a threat to the existence of some native species in Brunei Darussalam. These species produce large quantities of lignocellulosic biomass from the tree parts comprising the phyllodes, trunk, bark, twigs, pods, and branches. This study examined the thermochemical characteristics and pyrolytic conversion behavior of these tree parts to assess the possibility of valorization to yield bioenergy. Proximate, ultimate, heating value, and Fourier Transform Infrared Spectroscopy (FTIR) analyses were performed t

The term microfibril angle (MFA) in wood refers to the angle between the spiralling cellulose fibrils and the long axis of the tracheid cell wall. Diffraction patterns arising from crystal planes of various sample forms of wood trees had attracted scientific research in determining the crystallographic measurements. As such the tropical hard wood in Sabah, Acacia mangium was chosen for experimental data. Age-contributing factors were measured; the angle of reflection (θ), relative intensity, full width at half maximum (FWHM), the nearest between two neighbouring atoms in the crystalline struct

Abstract The transportation process of the bull can induce stress, affecting decreasing body weight and causing a loss for farmers. This study focuses on body loss affected by transportation from Magetan to Bogor and recovery after transportation. This research used 10 cross-breed bulls from Magetan East Java and transported them to Bogor West Java for 16 hours. The bull weighed on Magetan before being transported and Bogor after a 10-hour recovery. The first experiment compares transported bulls and non-transported Bulls.

In the present study, we compared the physical and mechanical properties of polyploid Acacia (3x and 4x) clones with those of diploid (2x) clones grown in Vietnam. We randomly selected 29 trees aged 3.8 years from different taxa for investigation. BV10 and BV16 clones represented the diploid controls; X101 and X102 were the triploid clones; and AA-4x, AM-4x, and AH-4x represented neo-tetraploid families of Acacia auriculiformis, Acacia mangium, and their hybrid clones.
