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). Each of with were made in 3 replications, re-drying process was then done to let the west reache its optimum moisture content. Concentration 3 replications were made.

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

The science advancement in this century is such that in the future it will enter the nano technology. More specifically in the forest products field, the nano technology that can be developed is among others nano carbon derived from lignocelulosic stuffs. In relevant, this research aims to provide information and technology on the charcoal processing from lignocellulosic stuffs into nano carbon. The lignocellulosic stuffs used in this research consisted of teak wood and bamboo, further carbonized into charcoal at 400-500°C using drum kiln. The resulting charcoal was examined of its physical and chemical properties, crystalinity degree and dielectric characteristics, and then purified by re-carbonizing it at 800°C for 60 minutes. Prior to the purification, the charcoal sustained the doping (intercalation) process with Zn, Ni and Cu metals each respectively. After the purification, the charcoal was ground to very tiny particels using HEM (high energy machine) device for 48 bours. In this way, the charcoal with high crystalinity was yielded, and further sintered using spark plasma at 1,300 C into the nano carbon. The qualities and structure of all the resulting carbon (carbonized charcoal, re-carbonized charcoal, intercalated charcoal and sintered nano carbon) were evaluated using nano scale device (Py-GCMS, SEM-EDX and XRD), and examined as well of their dielectric characteristics. In turns out that the best quality charcoal was obtained from teak wood charcoal carbonized at 800°C, intercalated with Ni atoms at the ratio 1:5. The resulting charcoal afforded high crystalinity (78.98%), low electric resistance (0.17 2), and high conductivity 175.52 2'm Qualities of the corresponding nano carbon (after sintering) were such that its crystalinity spectaculary reached 81.87%, resistance (R) 0.01 & with very bigh conductivity 1067.262'm'. The nano carbon that resulted seems favorably prospective for bio-censor, bio-battery, and bio-electrode. Accordingly futher related research deserves carrying out.
