Abstract

There are three dominant kinds of wood industries in Indonesia which consume huge amount of  wood materials as well as generate considerable amount of  woody waste stuffs, i.e. sawmills, plywood, and pulp/paper. For the two latest industries, their wastes to great extent have been reutilized in the remanufacturing process, or burnt under controlled condition to supplement their energy needs in the corresponding factories, thereby greatly alleviating environmental negative impacts.  However, wastes from sawmills (especially sawdust) still often pose a serious environmental threat, since they as of this occasion are merely dumped on sites, discarded to the stream, or merely burnt, hence inflicting dreadful stream as well as air pollutions. One way to remedy those inconveniences is by converting the sawdust into useful product, i.e. briquetted charcoal, as has been experimentally tried. The charcoal was at first prepared by carbonizing the sawdust wastes containing a mixture of the ones altogether from the sawing of seven particular Indonesias wood species, and afterwards was shaped into the briquette employing various concentrations of starch binder at two levels (3.0 and 5.0 %) and also various hydraulic pressures (1.0, 2.5, and 5.0 kg/cm2).  Further, the effect of those variations was examined on the yield and qualities of the resulting briquetted charcoal.The results revealed that the most satisfactory yield and qualities of the briquetted sawdustcharcoal were acquired at 3 % starch binder concentration with 5.0 kg/cm2 hydraulic pressure. As such, the briquette qualities were as follows: density at 0.60 gram/cm3, tensile strength 15.27 kg/cm2, moisture content 2.58 %, volatile matter 23.35 %, ash content 4.10 %, fixed carbon 72.55 %, and calorific value 5,426 cal/gram. Those qualities revealed that the experimented briquetted sawdust charcoal could be conveniently used as biomass-derived fuel.

Abstract

This study was carried out in 2005 at a peat swamp forest company in Jambi. The aim of this study was to find out a technique to increase the utilization of renghas wood in a peat swamp forest by implementing the lowest possible felling technique (LPFT) and  the conventional felling technique (CFT). Data collected in this study were: working time, log volume, waste volume, productivity, efficiency, stump height and felling cost. Two data categories were analyzed with respect to their possible differences by using a t-test.The study showed that the implementation of LPFT produced better results compared to that of CFT which was indicated by: (1) Felling productivity increased to 5.220 m3/hour, (2) Felling cost decreased Rp 341/m3, (3) Felling efficiency increased 3.2%, and (4) The average stump heights were 41.2 cm for LPFT and 67.5 cm for CFT.

Abstract

This study investigated the applicability of liquid medium in direct organogenesis of in-vitro culture of Melia azedarach L. Explants were collected from in-vitro multiplication originating from aseptically germinated seedling and from a 48 - years old mature tree. For adventitious shoot differentiation, 2 mm length of excised explants were cultured on liquid medium of MS (Murashige and Skoogs) basal medium supplemented with 28 combinations of hormone BAP (6-benzylaminopurine) and NAA (á- naphthaleneacetic acid). Differentiated shoots were subsequently cultured for shoot elongation in solid medium using MS basal medium supplemented with hormone BAP individually as well as in combinations with NAA. Finally, rooting culture were done using MS medium supplemented with IBA (3  indolebutyric acid). The results showed that the rate of shoot organogenesis of M. azedarach could be obtained through agitated liquid medium culture technique. The combination of hormone BAP 0.1-1 µM and NAA 0.01-0.1 µM are induced more adventitious shoot at a rate of 5 shoots / 2 mm length size of explants are transferring into rooting medium containing IBA 4.92 µM.

Abstract

This study shows an effort to obtain the best performance of Eucalyptus pellita trees, which was conducted by examining the physical properties of wood of 116 months age Eucalyptus pellita trees. The trees of various families used in this study were all grown in Seedling Seed Orchard (SSO), Pleihari. A total of 10 families with 3 individual trees for each family as replication were randomly selected for the whole SSO.   Selected sample trees were felled, cut and divided into three different parts (bottom, middle and top) of the stem. Each stem part was then cut into wood samples running from pith to bark portion for the examination of its physical properties according to British Standard BS 373-1957. The collected data on those properties were analyzed by using a completely randomized design (CRD). The results showed that there were significant differences in wood density and fiber length among different height, and among wood sections from pith to bark in individual trees as well as among families. Wood density showed high family heritability (0.708) and genetic correlation between wood density and fiber length were significantly different (r = 0.543).

Abstract

Establishment of seed orchard is aimed at producing good quality seeds which is an important activity for breeding program. Seed orchard is also a base population, thus its genetic diversity is depending on its design and composition (provenance, family and individual tree). Selection of an individual tree in seed orchard is needed for the enhancement of  retaining good-character trees. However, selection of individual tree can change the genetic diversity of seed orchard, and the degrees to which the genetic diversity will change depend on the used selection methods. In order to investigate the effects of selection methods, 4 simulations of selection methods based on height, diameter and stem performance of individual trees were used. The differences among the 4 methods were the ranking of individual trees those selected, and families and provenances those have been represented. Seedling seed orchard of Acacia mangium in Wonogiri, Central Java was used as materials.Analysis of genetic diversity was carried out using AFLP markers. Nine primer combinations were used to produce 1025 AFLP banding patterns. Among those banding patterns, only 109 were polymorphic markers. No significant effect of individual tree selection was revealed in this study. Even though the selection was done intensively, only 7.1% of genetic diversity was reduced. In other words, the selection activity did not reduce the genetic diversity of seed orchard significantly. The result is important for developing future tree improvement of A. mangium, including development of hybrid between A. mangium and A. auriculiformis.

Abstract

Gaharu wood stand has an important source of profits to the forest community in South and Southeast Asia tropical forest countries, but Aquilaria species have reduced in number and turn out to be endangered due to overexploitation.   Today,   the planting stocks of   Aquilaria species are not sufficient to sustain the yield of gaharu wood and promote forest conservation.  The objective of this study was to determine   the effect of   five arbuscular mycorrhizal (AM) fungi: Entrophospora sp., Gigaspora decipiens, Glomus clarum, Glomus sp. ZEA, and Glomus sp. ACA, on the early growth of  Aquilaria malaccensis and A. crasna under greenhouse conditions. The seedlings of  Aquilaria spp. were inoculated with Entrophospora sp., Gi. decipiens, Glomus clarum, Glomus sp. ZEA, Glomus sp. ACA and uninoculated (control) under greenhouse conditions. Then, percentage AM colonization, plant growth, survival rate and nitrogen (N) and phosphorus (P) content and mycorrhizal dependence (MD) were measured. The percentage AM colonization of A. malaccensis and A. crasna ranged from 83 to 97% and from 63 to 78%, respectively. Colonization by five AM fungi increased plant height, diameter, and shoot and root dry weights. N and P content of  the seedlings were also increased by AM colonization. Survival rates were higher in the AM-colonized seedlings at 180 days after transplantation than those in the control seedlings. The MD of Aquilaria species was higher than 55 %. The results suggested that AM fungi can be inoculated`to Aquilaria species under nursery conditions to obtain vigorous seedlings, and the field experiment is underway to clarify the role of AM fungi under field conditions.

Abstract

Coconut palm (Cocos nucifera L.) is known as multi-purposes tree as almost all part of the tree can be utilised. Coconut timber utilization is limited on hard or denser part, while lighter coconut timber remains unused. Theoretically, mechanical densification could improve physical properties of light coconut timber, which may be useful for diversifying its uses. This study examined some anatomical changes in coconut wood that occurred during mechanical densification. Coconut wood samples measuring 40 mm thick, 40 mm wide and 50 cm long were steamed at 1260C for 30 minutes prior to being compressed by 23.75 kg/cm2   pressure. Anatomical measures were undertaken using light microscope and scanning electron microscope on both non-compressed and compressed samples. Results showed that the treatment significantly reduced void volume and increased vascular bundles frequency, decreased vessel and parenchyma cell diameter. The wood density also increased by more than 50%.
