Abstract

Liquid smoke was formed as condensation product during the process of wood pirolysis at temperature around 400°C). Phenolic compounds, aldebrydes, ketones, alcohols, organic acids and ester, could functioned as antimcidants and anti-microbes (anti-bacteria and anti-fungi). This research aimed to study the effectivity of liquid smoke from coconий shell waste as alternative agent to control the attack by seed pests (i.e. fungi) on the plant seed stored in the wareboun, of the Plant Serding Departement, Vocational Education Development Center for Agriculture (VEDCA). The Initial step of the research was the production of liquid smoke from coconut shell, the obtained liquid smoke was then sprayed everly auto corn seeds and soybean seeds at four different concentration: 0%, (control), 0.5%, 1%, and 2% (v/v).

Abstract

Particleboards as one kind of the reconstituted wood products in their manufacture still rely on the Sonventional wood material from natural forest, which in potency becomes limited and scarce. Consequently, use of alternative woods or other ligno-cellulosic fibrous stuffs deserves thorough consideration, with their potency abundant and mostly still unutilized, such at bagasse (sugar-cane fibers) waste from sugar factories. In relevant, a research on particle board manufacture avus conducted using bagasse particles bonded together with urta-formaldehyde (UF) adhesive. This research aimed to look into the effect of UF content (i.e. 6%, 8%, and 10% based on the dry weight of the particles) on the physical-mechanical properties of the resulting particleboard. Results revealed that increasing the UF content brought about a significant decrease in the thickness swelling and water absorption of the board; and increases in MOR, MOE, and crew-withdrawal strength, but inflicted so significant changes on the moisture content, density, and internal band. Particleboard properties that could favor the standards of consecutively Indoncia (SNI), Japan (JIS) and FAO either entirely or partially were density, moisture content, and MOR. The greatber the UF content, the more of those properties satisfying the JIS spesification. Judging from in density, this experimented particleboard was more suitable for ate at room deathing and frumed table-plane. The particielswars that looks the neust prospective for such purposesmere those ning UF at 8% content.

Abstract

Charcoal and wood vinegar exert significant role as carbon sources yielded from the carbonization process, and afford multi benefits in their use for enhancing plant growth and stimulating carbon nutrient absorption. In relevant, this scientific narration presents results of trial tests employing charcoal and wood vinegar on the growth media for sprouts of sengon, jabon and agarwood producing plants, which lasted for 6 months at the planting experiment site. This experiment aimed to scrutinize the growth responses of such plant sprout species; and the examine the contents of carbon, nitrogen, phosphor, potassium in the soil and in plant biomass after being added with charcoal and wood vinegar. Charcoal addition proceeded by mixing it with soil evenly, while wood vinegar addition was done by showering it on to the soil. Nurturing of plants took place by spraying wood vinegar on their stems, branches, twigs and leaves. Results revealed that the additions of charcoal and wood vinegar on the growter media for sengon sprouts increased as much as 127-208% in beight and 109-129% in diameter of the corresponding sengon plants. For jabon plants, the addition of charcoal and wood vinegar brought about in increase 117-142% as much in their beight, and 166-128% in their diameter. Meanwhile, for eaglewood producing plants there appeared still no significant growth effect attributed by such addition, since it seemingly took considerable time for them to adapt themselves. Further, the incorporation of charcoal and wood vinegar brought about an increase of carbon nutrient adsorption in the soil and biomass. Besides carbon (C), adsorption of N, P, and K nutrients also increased.

Abstract

This study deals with the trial on teak wood-log extraction on a steep terrain using skyline system. This system used a small capacity yarder machine (5.5 PK) of generation II's Expo prototype. The wood log was pulled from a tree-felling plot all theway about 50-m distance to the bill slope. As such, the yarder afforded the productivity in average 0.6263 m²/hour, implying that it was still below the targeted range (2.5-5m/bour). The investment cost reached Rp 72,000,000 or correspond to Rp 102,986/bour or Rp 156,351/ ni'. Financial analysis using the actual performance of such tool at the rents price similar to the log-extracting cost brought out negative NPV and IRR values. Such values could have been positive had the rents price been greater, equal to Rp 185,000/m².

Abstract

Kerangas forests typifies as tropical-rain vegetation trees, characterized by among others their low nutrients contents and sparse biodiversities, thereby denying their tree uses. The kerangas forests grow widespread in Kalimantan (e.g. South Kalimantan). Among the species that can grow and with stand such extreme condition is merapat (Combretocarpus rotundatus) trees. Their leaves contains particular chemical compounds that indicatively afford physiological bioactivities e.g. antioxidants. Consequentys this could expectedly emulate the added values for merapat tree uses. In relevant, scrutiny on phytochemical compounds and testing of such antioxidant efficacy were conducted on the samples of dry merapat tree-leaves taken from the kerangas forest in South Kalimantan. Initially, the dry leaves were extracted with methanol solvent, which yielded the methanol extract (i.e. sample 1), further fractionated by the column chromatography using chloroform eluant. The obtained chloroform-eluted fractions (sample 2) were fractionated again by the misced ethyl acetate-chloroform solvents (in equal proportion), which yielded the so-called sample 3. Phytochemical scrutiny revealed that the methanol extracts contained particular compounds such as flavonoids, phenol derivatives, bydroquinone, tannin, and triterpenoids, wich among them afforded the anticocidant efficacy. The methanol extract (sample 1) exchibited the very strongest antioxidant action by inflicting such reduction reaction on the free radicals released by the DPPH (2,2-diphenyl-1-picrylhydrazyl), while such action exerted by the chloroform-eluted fractions' sample 2 and the ethyl-acetate-chloroform-eluted fractions' sample 3 was very little. The inhibition of free-radical formation from DPPH as much as 50% (IC50) occurred at 21.82 ppm of the methanol-extract concentration. Meanwhile, vitamin C and BHT as the control antioxidants performed more efficiently at much less than 21.82 ppm (i.e. 6.74 and 6.28 ppm, respectively). However, such IC50 value strongly suggests that the merapat leaves' methanol extract afforded the potential bioactivity as antioxidant.

Abstract

Preserving wood is one way to enhance its natural durability. The degree of wood protection achieved depends on the preservative impregnated in the wood and measured by its retention and penetration. Preservative retention is calculated based on the gravimetric system, while penetration is observed based on the colour differences after spot test. Preservative penetration pattern is observed visually and percentage is calculated conventionally. Digital image interpretation using Image-J software is one way to measure the preservative penetration. This paper studies the treatability of six wood species from West Java and Riau. Preservative penetration was interpreted both conventionally and digitally. Result shows hamirung, jaha and mahang putih wood species are classified into easy to preserve (class I), while bung bulang, pasang taritih and bira-bira wood species are classified asmediumto preserve (class II). Digital image identification provides easier, faster and more accurate in interpreting preservative penetration than the conventional method.

Abstract

Agarwood signifies as one of the non-timber forest products (NIFPs) comodities in Indonesia. The form of agarwood varies, such as lumps, chips, flour, until oil. Agarwood in incense shape will give off smells, if burnt. This experiment aimed to identify chemical components in four grades of agarwood from the best to the lowest i.e. kacangan B, teri B, kamedangan A dan kamedangan B. Identification was performed by extracting the agarwood with acetone solvent, and then the acetone extract was fractionated using gradient column chromatography method with n-bexane-ethyl acetate as eluent. Identification of compounds proceeded using gas chromatography-mass spectrophotometer Results of identification revealed that there were sesquiterpene compounds in the four grades of agarwood (i.e. kacangan B, teri B, kamedangan A and kamedangan B), but kinds of compounds were different from one grade to other. Chromone compounds only existed in 2 grades of agarwood covering kacangan B ubich bad 2 compounds (6-bidroxy-2-methyl-5-nitrochromone), and 3-metaxxymethyl-2,5,5,8a-tetramethyl-6,7,8,8a-tetrabydro-5H-chromone), and kamedangan A with only one compound (2,2-dimethyl-6,7-dimetawcychromone). The presence of sesquiterpene and chromone with particular portion and characteristic in each of those four agarwood grades indicatively bears their role explaining their grades from the best until the lowest.
