Abstract

Nowadays, the potency of conventional fibrous materials (ie, woods) for the manufacture of medium-density fiberboard (MDF) becomes depleted and scarce. Use of alternative fibers which are abundantly available and still largely unutilized, i.e. nypha midribs and coconut coirs, bas been attemped for MDF (medium-density fiberboard), using urea-formaldebryde (UF) adhesive However, such study showed that MDV from each of the two fiber sources could not satisfy the JIS and ISO standards. In relevant, improvement trial on MDF properties was accomplished using both kinds of fibers. Intially, those fiber stuffs had their basic properties examined, i.e. specific gravity, chemical composition, and fiber dimensions and their derived values. The MDF's fibrous pulping employed a bat semi-chemical soda process under atmospheric pressure at two alkali concentrations (8% and 12%). The resulting pulps were then added with additives, i.. 5% alum, 5% tannin formaldebryde (TF) adbesive either incorporated with activated charcoal (5%) or not; and then shaped into MDF mat using wet process, Physical-strength properties and formaldebryde emission of the resulted MDF wery examined. Assessing those properties, nypa-midrib fibers were more prospective for MDF than coconut-coir fibers, Activated- charcoal addition lowered MDF's formaldehyde emistion and improved dimensional stability, but decreased its strengths. In properties, MDF, from nypa fibers 100% were significantly the closest in satisfying the standard (JIS and LSO). Yet, coconut-enir fibers could still be prospective for MDF by missing them (pulp form) with wypa-fiber pulp at the propertion (w/w): 25%+75% and 50%+50%. The MDF with TF adhesive afforded better properties than the previous experiment (UF), n. greater strengths, lowered emotion and satisfying more of the 115 and ISO standard.

Abstract

Rattan is spiny climbing palms, which is mostly utilized for furniture. This paper determines the chemical composition of 12 rattan species from Papua and its resistance against powderpost beetle (Dinoderus minutus Fabr.) and subterranean termite (Coptotermes curvignathus Holmgren). Chemical composition tested includes cellulose, lignin and starch contents. Cellulose content was determined by Norman and Jenkins method, while lignin content was determined based on the Indonesian National Standards (SNI 14-0492-1989 and SII-70-1979). Rattan resistance against powder post beetles and subterranean termites according to Indonesian Standard SNI 01-7207-2006. Results show that the highest cellulose content was found in somi-1 rattan (Calamus pachypus WJ Baker & al) of 52.82%, while the lowest cellulose content was found in longipina rattan (Calamus zebrianus Becc) which constitutes 42.29% cellulose content. The highest lignin content was recorded in endow rattan (Calamus zebrianus Becc) which was 33.37%, and the lowest was recorded in itoko rattan (Calamus vitiensis Warburg) which was about 21.00%. Two rattans studied were classified into class I against powder post beetle, and three of them were classified as class II. Four rattan species falls into class III and one species classified as class IV, and the other two species were classified as class V against powder post beetle. Based on the test against subterranean termites, three rattan species were classified as class I, five species as class II, two species as class III, one species as class IV, and one species as class V. Rattan species which was classified into III, IV, and V classes need to be preserved to enhance its service life.

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

Indonesia's tropical natural forest woods are conventionally still raw materials for MDF, which in potency becomes depleted and scarce. Consequently, use of alternative fibrous materials deserves thorough consideration, with their potencies abundant and mostly still unutilized, such as Nypa frutican midrib and coconut coir. In relevant, an experiment was conducted to utilize both kinds of fiber for MDE Those fiber stuffs were each passed through the preparation, and examination of their basic properties (i.e. specific gravity, chemical composition, and fiber dimensions and their derived values). The fibrous pulping for MDF employed a bat semi-chemical soda process under atmospheric pressure, followed with the refining action to achieve pulp freeness at 600-700 mil CSF. The refined pulp were then added with additives (i.z. 4% alum, 3% UF-adbesive, 5% activated charcoal), and then shaped into MDF mat using wet process, followed with beat treatment, bot pressing, conditioning, and ultimately the testing of MDF properties. Scrutiny on MDF physico-strength properties revealed that nypa-midrib fibers were more prospective for MDF than coconut-coir fibers. Activated-charcoal addition lowered the MDF formaldehyde-emission, but decreased its strengths. In properties, MDFs from nyta fibers significantly outperformed those from coconut-cnir fibers in complying with the standard (JIS). Yet, connut-nir fs could still in prospective for MDF by mixing them (pulp form) with nypa-fiber pulp at the proportion (w/w): 25%+75 and 50%+50%
