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

In Indonesia, Gyrinops is one important genera of agarwood producing trees, which is relatively slow growth. Stimulant addition is one possible way to enhance agarwood tree growth by improving the physiology activity. This paper studies the effect of charcoal and liquid smoke addition into the Gyrinops sp. seedling growth. Wood charcoal at various portion of 10%, 20% and 30%, and liquid smoke of 1%, 2%, 3% and 4% were added separately into seedling media. The charcoal and liquid smoke were made from mixed wood waste of sengon (Falcataria moluccana) and rubber wood (Hevea brasiliensis). Results showed that in general wood charcoal and liquid smoke addition improves Gyrinops seedling growth. The addition of 4% liquid smoke addition enhanced Gyrinops’s seedling growth as indicated by seedling height and diameter increments. In conclusion, wood charcoal and liquid smoke are two potential organic materials for seedling growth improvement.

Abstract

Currently, Ganoderma lucidum, Pleurotus ostreatus, and P. sajor-caju are prospective fungi for decomposition of pulp and paper industry’s waste. This paper studies the possible utilization of rotting fungi spent compost for decomposition of mangium sludge. Initially, the fungi were cultivated for three months on medium prepared from sengon (Falcataria moluccana) wood sawdust. The rotting fungi spent compost was then used for degrader activator by inoculating them into the Acacia mangium sludge, then, incubated for six months. Results revealed that after three month incubation the values of the Biological Conversion Efficiency (BCE) of sengon reached 13.41% (G. lucidum), 47.11% (P. ostreatus), and 38.06% (P. sajor-caju). Fungal inoculation into the sludge improved the C/N ratio as much as 71.59%. The usage of higher concentration of G. lucidum inoculums increased the C/N ratio value. After six months incubation, some sludge contents reduced by 48.76% (N), 35.42% (P) and 25% (K), except for Ca and Mg, which increased by 112.9% and 6.67%, respectively. Mineral content of the untreated sludge decreased by about 66.12% (Ca), 68.75% (P) and 4.17% (Mg), except for K and Ca which were increased by 2.08% and 64.52%, respectively. Cation exchange capacity (CEC) value of the sludge after incubation increased by about 3.85% (control) and 56.8% (treated).

Abstract

The research aimed to look into the growth responses of sengon, jabon, and agarwood seedlings; and to examine the carbon (C), nitrogen (N), phosphor (P), and potash (K) contents in soil as well as in the biomass portions of those three plant species (i.e. their leaves, stems, and roots) after being added with charcoal and wood vinegar. It also intended to explore the potency of carbon store in such plant-biomass portions. The charcoal addition was conducted by mixing it with soil evenly and homogenously, while wood-vinegar incorporation proceeded by spraying it onto the soil. For taking care of the plants, the wood vinegar was sprayed periodically to their stems, twigs, and leaves. Results revealed that the growth of sengon seedlings achieved the greatest in height (156.33 cm) and in diameter (20.08 mm), attributed to the addition of wood vinegar (2%) and charcoal (10%). For jabon seedlings, the greatest growth in height (89.17 cm) and in diameter (19.22 mm) occurred due to addition of wood vinegar (4%) and charcoal (20%). For agarwood seedlings, the greatest growth height (72.20 cm) and in diameter (18.29 mm). Besides, the addition of charcoal and wood vinegar could not also bring about the increase in consecutively nutrient contents (e.g. C, N, P. and K), biomass weight, and carbon store, which varied in the leaves, stems, and roots, in accordance to the percentages/ dosages of those two agents as added.

Abstract

Currently, bioethanol is one of biofuels which is potentially developed for new and renewable alternative energy. Bioethanol could be fermented from agriculture and forest wastes, with pre-treatment and hydrolysis process before the fermentation. Those process could be carried out by an addition of microbe (yeast). In order to gain greater ethanol content, yeast mixing formulation is crucial to obtain optimum ethanol content. This paper studies the formula of yeast mixing for optimum ethanol production of sengon wood waste. Formulation was conducted by mixing Aspergillus oryzae, Saccharomyces cerevisae, Rhyzopus oryzae and other substances with various treatments. Commercial yeast of 3 – 9% Sacharomyces cerevisae was used as a comparable control. Results showed that 7% yeast mixing was effective to produce 1.569% ethanol content from lignocellulose fermentation. The ethanol content is relatively greater than those of commercial yeast which constitutes of about 0.652% ethanol content.

Abstract

Dryobalanops aromatica Gaertn is a woody plant that produce oil and crystal which has high economical value. Currently oil and crystals becomes an export commodity for cosmetics and pharmaceuticals purposes. In the community, oil utilization is still limited for simple medication in various minor ailments. Utilization in domestic area is still very limited, thust it is necessary to conduct research that lead to increase additional value of the oil. Utilization as fragrance materials/perfume is expected to increase the added value. Result showed, the preferred perfume formula is that with formulation of Dryobalanops oil (25%), ethanol (75%) and green tea additives as odorant, PG and patchoulioil (0.8%). The characteristics of formula have a soft fragrance level, with sharpness level at rather sharp fragrance. Dryobalanops aromatica oil has borneol as marker compounds. And the other chemical compound, such as Caryophyllene; 3-Cyclohexene-1-methanol, .alpha., .alpha., 4-trimethyl-, (S)- (CAS) p-Menth-1-en-8-ol, (S)-(-)-; 1,4, 7-Cycloundecatriene, 1,5,9,9-tetramethyl-, Z,Z,Z- dan 3-Cyclohexen-1-ol, 4-methyl-1-(1-methylethyl)- (CAS) 4-Terpineol.
