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

Production of biodiesel catalytically requires catalyst and stirring. Good stirring system will produce a homogeneous mixture between triglycerides and methanol. Good stirring can be generated with the use of static mixers. This paper studies the static mixing reactor with continuous system in production of biodiesel catalytically and optimizing the length of static mixer in order to obtain methyl ester level based on standard. The experiments were conducted with transesterification method using palm olein (RBDPO) and methanol with molar ratio 1:6, KOH catalyst of 0.5% and the reaction temperature of 65°C. Biodiesel production process used transient condition. Biodiesel production process with catalyst used two models of static mixer. The treatment was the length of the static mixer. The variations of the static mixer length were conducted by passing fluid one time through static mixer reactor after the temperature has been reached (A0 = 2 static mixer), passed two times through the static mixer reactor (A1 = 4 static mixers), passed three times through the static mixer reactor (A2 = 6 static mixers), and passed four times through the static mixer reactor (A3 = 8 static mixers). Results show that for each treatment had produced methyl ester content above the standard of 96.5% w/w. The determination of the best treatment was obtained based on the best value for parameters of methyl ester and total glycerol resulted was on the condition of 4 times passed in the static mixer reactor (A3 = 8 static mixers) which produced methyl ester content of 97.92% w/w, total glycerol of 0.85%, acid number of 0.31 mg KOH/g, saponification number of 202 mg KOH/g, the biodiesel yield of 98.26%, and reaction time 29 minute.

Abstract

The resistance of twenty bamboo species from different regions of Indonesia were tested against drywood termites (Cryptotermes cynocephalus Light.). Each bamboo species was cut into dimension of 5 cm × 2.5 cm × 1 cm. The test was conducted according to SNI 7207-2014. Parameters mass loss percentage of bamboo, survival rate of the termites, and degree of attack (subjectively) were observed as the basic to classify the resistance of bamboo against drywood termites. According to the mass loss percentage, the bamboo species were assigned into five groups: two bamboo species as resistance class I, six bamboo species as class II, five bamboo species as class III, four bamboo species as class IV, and three bamboo species as class V. Based on the survival rate of the termites, the natural resistance of bamboo could be assigned into five groups: two bamboo species as resistance class I, one species as class II, ten bamboo species as class III, five bamboo species as class IV, and two bamboo species as class V. The classification according to the degree of attack showed that two bamboo species experienced severely attack (38 - 40.5% / score 90), while the rest eighteen bamboo species had medium attack (18.4 - 34.9% / score 70).

Abstract

White-rot fungus, Basidiomycetes is an unique group of microbes among the major decomposers of plant polymers or biomass. Their existences are under pressure due to Indonesian tropical forests degradation caused by forest fires, excessive exploitation, land conversion and biopiracy. Based on natural process of white rot fungi, it could be utilized for bioresources, i.e improvement of food quality and leading of new functionality (the food industry), delignification (pulp & paper), production of ethanol (biofuel), biosensors and bioremediation. This paper studies isolate, selection and evaluation of the potential extracellular enzymes laccase (Lac) and manganese peroxidase (MnP) from fungi grown in Indonesian tropical forest. A total of 178 samples of fungi fruit were collected from Indonesian tropical forest, including West Java, East Java and East Kalimantan Provinces, then they were isolated and selected on RBBR agar media for futher analysis. The results showed that there were significant differences of 26 pure isolates, in term of its capacity to decolorize RBBR, and only six pure isolates (JB-7.1.1, BST-F16, Gr-W3.2A-C, TRK-1, TRK-2, and TRK-3) were able to oxidize RBBR more than 1 cm per day. Futhermore, two isolates were selected as their enzymes production was higher than another, those were -1-1 JB-7.1.1 (Lac = 526 ± 142 UL and MnP = 114 ± 13 UL ), and TRK-2 (Lac = 463 ± 95 UL and MnP = 98 -1-1 ± 8 UL ). Statistically, the activity of Lac produced by JB-7.1.1 was higher and not significantly different with the positive control, Cerrena sp. F0607. JB-7.1.1 and TRK-2 isolates were the potential fungi for producing Lac, which they could be applied easily for textile dyes decolorization as bioremediation.

Abstract

Bamboo is potential as an alternative material to substitute wood. This paper examines the effects of using different resin contents and strand dimensions on the properties of its oriented strand board (bamboo OSB). Tali bamboo (Gigantochloa apus (J.A. & J.H. Schultes) Kurz) was used as raw material in manufacturing the bamboo OSB. Laboratory scale oriented bamboo strand boards were fabricated using each bamboo strand length (7.5, 10, and 15 cm) and glued with liquid phenol formaldehyde adhesive at various resin contents (6, 7 and 8%) of the bamboo strands dry 3 weight. Results show that the average density of fabricated bamboo OSB was 0.75 g/cm . Physical and mechanical properties of bamboo OSB were significantly affected by resin content, except the modulus of elasticity (MOE). Higher resin content gave better physical and mechanical properties of the boards. MOE of bamboo OSB was also significantly affected by the strand length. The longer strand dimension produces boards with higher MOE values. All oriented bamboo strand boards studied meet the Indonesian and Japanese Standard requirements of type 24 particleboard and also meet the British Standard requirements of both Type OSB/2 and Type OSB/3.

Abstract

In general, pine resin yield is affected by various factors i.e. pine tree species, growing environment and tapping method. This paper studies pine resin tapping yield by drilling method using H₂SO₄ stimulant. Tapping point is designed in the depth of 4, 6 and 8 cm and sloping 25°. Three stimulant concentrations (0, 15%, 30%) were brushed in the tapping point and the treatments were repeated 10 times. Experimental design based on 3 × 3 factorials in completely randomized design. The first factor is the depth of drilling holes, the second factor is the concentration of H₂SO₄ stimulant used and repetition of 10 times. Pine resin yields were analyzed using analysis of variance and further test was conducted by honestly significant difference test. Results show that tapping pine by drilling and stimulant addition produced pine resin between 15.5 to 109.3 g / tree / collection (56.3 g / tree / collection on average) or between 2.6 to 18.2 g / tree / day (9.4 g / tree / day on average). Pine resin yield is significantly influenced by drilling hole depth and H₂SO₄ stimulant concentrations. The deeper the drilling hole, the more pine resin yield, and the higher the concentration of H₂SO₄ stimulant the higher pine resin yield. Pine resin yield of 8 cm tapping depth is 65.96% higher than 4 cm tapping depth, and 30% H₂SO₄ improved the yield by about 56.45%. The largest pine resin yield is achieved from tapping point of 8 cm depth and 30% H₂SO₄ that yiled about 90.7 g / tree / collection in average.

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

Alstonia scholaris R.Br belongs to family Apocynaceae, is one of medicinal forest plant as traditional medicine to treat fever, malaria, cough with phlegm, diarrhea, diabetes, cholesterol-lowering, intestinal worms, acute rheumatism, ulcers, and hypertension. One of the causes of heart disease, atherosclerosis, and cancer is oxidative stress. The stress can be cured or reduced by taking antioxidant. Flavonoid, a phenol compound class, is one of the secondary plant metabolites that function as antioxidant. This paper determines total levels of phenol, flavonoid, and antioxidant activity of Alstonia *stem bark extract (Alstonia scholaris R. Br). Quantitative determination of total phenolics with the folin-ciocalteu method expressed as mg of gallic acid equivalent (GAE) per gram of extract, total flavonoids content by AlCl₃ method expressed as Quercetin equivalent (QE), and in vitro antioxidant activities with DPPH (2,2-diphenyl-1-picrylhydrazyl) method expressed in terms of IC₅₀ (inhibition concentration). Results show that extraction of three replicates in maceration with 96% ethanol yielded 4.19% filtrate. The total phenolic content was 51.50 mg GAE /g extract, while the total flavonoid content was 0.35 mg QE /g extract. IC₅₀ value of antioxidant activity assay of stem bark extract was 211.54 µg/mL.
