Abstract

Commercial wood putty products available in the market nowadays are mostly chemical solvent-based, such as epoxy and latex. These products give desirable physical, mechanical and chemical performances, however their volatile organic compounds are detrimental to the environment and harmful to the health. This paper explores the use of teak fine powder mixed with shellac and putty powder as an alternative formulation of organic wood putty. These alternative formulas were tested on tusam and rubber wood by assessing their physical, mechanical and chemical performances in comparison with the most commercial putty products, i.e. epoxy (DK1) and piroxylin (DK2). Samples of two wood species were treated by spreading them with various wood putty solutions. Weight and dimensional changes due to treatment were determined in wet and dry sample conditions. Results show that weight and dimensional gains due to spreading treatment varies according to wood species, grain orientation and putty solution. Tusam samples possessed greater weight and dimensional gains than those of rubber wood samples. All organic putty formula was able to protect wood from water intrution, but less effective than the commercial putty DK1 and DK2. The organic wood putty had lower scratch resistance and less resistant against chemical liquids than the commercial ones.

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

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.
