Abstract

Fungi resistance of 5, 8 and 11 year old sap and heart Acacia mangium Willd wood, taken from Parungpanjang (West Java Province) and Serang (Banten Province) were evaluated using modified DIN 52176 standard. The result showed that wood samples from Parungpanjang was classified as moderately resistant to resistant (class III-II), while those from Serang district as non resistant (class IV). Both the sap and heart wood had similar resistance (i.e. class III). The percentage of the weight loss of the heart wood was lower than that of the sap wood. The lowest weight loss was found on 11 year old samples, taken from Parungpanjang district. The highest weight loss was found on 8 year old samples from the same area and on 11 year old samples from Serang. The most virulent fungus was Coriolus versicolor followed by Tyromyces palustris, Polyporus sp. HHB-209, Pycnoporus sanguineus HHB-324, Schizophyllum commune HHB-204, Postia placenta. The less virulent ones were Dacryopinax spathularia, Chaetomium globosum, Pycnoporus sanguineus HHB-8149, and Phlebia brevispora The highest weight loss was recorded on the sap wood of 8 year old samples from Parungpanjang exposed to Lentinus lepideus culture, the lowest was on the heart wood (from the trees of the same age and origin) exposed to D. spathularia culture. The resistance of wood could be affected by the tree-growth site, age, position in the log, species and strain of fungi

Abstract

Rosin is a mixture of abietic and pimaric acids with small amount of neutral materials. By modifying these acids could widen its utilizations. One of modified rosin is maleic rosin. This study is intended to find out the effect of acid concentration on yield and maleic rosin physico-chemical properties. The research target is to determine a proper condition for manufacturing of maleic rosin which could fulfill the standard requirements.The manufacturing of maleic rosin was carried out by elevating the temperature to 160 - 170 °C and maintained it at this temperature for 2-3 hours. Maleic acid that was used in the process consisted of 0 %, 2%. 4%, 6% and 8%. The physico-chemical properties of the maleic rosin produced was analysed. As raw materials. this experiment utilized rosin from North Sumatra (WW quality) and rosin from East Java (WG quality). The phsyco-chemical properties of the products were then analysed. The data were analysed by using factorial random design, and the different value between means was calculated with Tukey procedure by the SAS computer package.The results showed that the increase in maleic acid concentration caused to increase in yield, softening points. acid value. and saponification value of maleic rosin. The ash content value, however, did not exhibit certain tendency when maleic rosin were produced under the experimental condition applied. Rosin from East Java with WW quality produced maleic rosin higher softening point and saponification value than that of from North Sumatra with WG quality. Based on its softening point and dirt content, manufacturing maleic rosin with acid concentration 2 % in this experiment produced maleic rosin which could meet the requirement of second quality for Chinesse maleic rosin.

Abstract

The resistance of 109 Indonesian wood against subterranean termite (Coptotermes curvignathus Holmgren) attack has been assesed. The wood species come from several regions in lndonesia. The woods were each cut to small samples measuring to 2.5-cm by 2.5-cm by 0.5-cm and subsequently exposed to 200 subterranean termite workers for four weeks.The results revealed that 68 out the 109 wood species (i.e.62.3 percent) were classified as themost durable (classes I and II): and the rest, i.e 41 species (37.8 percent), were classified as lower durability (i.e. classes Ill, IV, and V) and therefore in their application need a preservative treatment.

Abstract

Ten year old Acacia mangium wood species from Sukabumi area (West Java) was used as the raw material of exterior type particleboard glued with phenol formaldehyde.Single layered particleboard with density target of 0.5 - 0. 70 g/cm3 with its nominal thickness of 1.50 cm. The dimension of particleboard was 30 cm x 30 cm x 1.50 cm. The treatment of wood particle were three kinds i.e. unsoaked, soaked for 24 hours and 48 hours in cold water. The objective of the study was to determine the effect of treatments on the physical and mechanical properties of particleboard. The result indicated that the modulus of rupture (MOR), air dry internal bond, the thickness swelling after soaked during 2 hours and 24 hours in cold water, 3 hours after soaked in boiling water and 3 hours soaked in boiling water and dried (absolute dry), moisture content and density of mangium particleboard met the Indonesian National Standard for particleboard. The treatment of wood particle soaked in cold water is not recommended.

Abstract

The experiment has been conducted on utilizing different types of charcoal as growth-stimulating agents by adding each of them to the growing media (i.e. soil stuff) of red pepper plant; and subsequently evaluating their effects on its growth characteristics/ responses. There were three types of agents used and added to the media, i.e. rice-husk charcoal, bamboo charcoal, and sawdust-mixed charcoal. respectively. For comparative purposes, were also measured the growth responses of the red pepper plant whereby its growing media were added with compost as well as the Bokasi rice-husk charcoal compost, besides the ones in the medium without the addition of any growth agents (as control). This experiment revealed some remarkable results. as follows:•              Additions of 5 % bamboo charcoal or l 0 % rice-husk charcoal could increase the height growth of the red pepper plant, in comparison with the one grown on the control medium:• Additions of 10 % rice-husk charcoal could increase the stem diameter of the plant by 11 % compared to the one on the control medium;•              Likewise, additions of 5 % and 10 % sawdust-mixed charcoal could each increase the stem diameter by consecutively l1 % and 10 %, in comparison with the control;•              Additions of 10 % bamboo charcoal brought about the best effect with respect to the increase in the number as well as the weight in red-pepper fruits in their first harvest (i.e. 3-month age), compared to the control:•              Additions of 10 % rice- husk charcoal, 5 % bamboo charcoal, and 10 % sawdust-mixed charcoal each brought about also the best effect with respect to the increase in the dry weight of the plant, i.e.consecutively 2.0, 2.0, and 1.8 times as such as that of the control;•                              Average amount of C02 absorbed by the red- pepper plants for 3 months was 0.10-0.88 gram per plant. The highest C02 absorption was achieved by the corresponding plants with addition of 10 % sawdust-mixed charcoal (i.e. 1.88 gram C02 per plant), followed in decreasing order by the ones added with 10% rice-husk charcoal and 10 % bamboo charcoal (i.e. 1.67 gram C02per plant and 1.34 gram C02 per plant, respectively).

Abstract

this investigation deals with manufacturing of compost and charcoal compost. The raw materials in this manufacture were foliage litters and bark of tusam (Pinus mcrkusii Jungh et de Vries) trees growing in West Java. Particular bio-activators, called as Orgadec and EM;. were used to stimulate the decomposition of those materials. This investigation lasts for about three months. The results revealed that the quality of several of the resulting charcoal composts comply with the related standards, with respect to among others : P = 1.12 - 1.24 percent; K = 1.47-1. 62 percent; Mg= 0.67-1.05 percent; moisture content 55.81-56.21 percent: pH 6.8-7.2; and C/N ratio 18,89-20./0. When compared to other compost, the charcoal compost revealed better qualities, since charcoal was added to it lo improve the properties of soil, i.e. increasing the pH and storing more water.

Abstract

Since 1998. Indonesia has been importing wood items in shapes and species from other countries. This situation should not happen if we were able to use local wood species optimally. Wood anatomy of Hibiscus macrophyllus and Artocarpus horridus have been described for identification purposes and evaluation of the appropriate uses.Several particular important features for identification have been observed, as follows : (a) axialparenchyma diffuse in aggregates in Hibiscus macrophyllus. and axial parenchyma aliform in Artocarpus horridus, (b) Ray and fibers storied in Hibiscus macrophyllus and helical thickenings in ground tissue fibers in Artocarpus horridus. (c) mineral inclusions present in Hibiscus macrophyllus in the form of prismatic crystals and druses.The effect of height (upper. middle, and bottom trunks) and distance from the pith (core of the trunk) was significant on fiber dimensions of Hibiscus macrophyllus and Artocarpus horridus. However, such interaction did not bring about significant effect on the fiber wall thickness. About fiber length, it decreased with height levels from the bottom toward the top portion of trunk. Meanwhile, the fiber length increased from the pith toward the portion adjacent to the bark.The relationships between distance from the pith (X) and fiber length (Y) of Hibiscus macrophyllus can be described in three regression equations, as follows: Y = 749 + 1896X + 998X2, R1= 0.4505 (top portion), Y = 664 + 2419X - 1410X2, R2 0.4729 (middle portion), and Y= 1431 + 430X 270X - R1 - 0.0249 (bottom portion). likewise, the corresponding three regression equations for Artocarpus horridus are Y 1177 + 1537X - 927X2 R2- 0.2538 (top portion), Y - 1037 + 1207X - 314X2,R2 0.5519 (middle portion), and Y = 1480 + 969X 674X2, R2= 0.0625 (bottom portion).The fibers of Hibiscus macrophyllus and Artocarpus horridus have a medium quality. These species are therefore suggested for pulp and paper. Hibiscus macrophyllus is suggested too for light construction and mebel.
