Abstract

An explosive development in oil palm plantations in the country has produced a consequence in the generation of  plantation wastes. The  disposal of these wastes  has created  an  enormous environmental problem that some practical solution to their economic utilization has to  be sought.  A series of experiments have been accomplished to observe the possibility of converting the oil palm stem into valuable woodworking products. The  first stage of  this effort was determining basic characteristics of oil palm wood.  Results in general showed that the wood has a great characteristic variation across and along the stem, which may develop problems in its utilization. Characteristics of this wood also vary according to species variety.  Quality degradations of oil palm wood were mostly happened during drying process; hence, modifications to upgrade quality should be undertaken before or within the drying process.

Abstract

Development of  meranti (S.leprosula) plantation forest is limited/ constrained by many factors, e.g.   seed supply and seedling growth environment. The research deals  with the observation of  the current condition on A.  mangium  stand and did not  employ any treatments.  Meranti seedling was obtained from vegetative cutting (Komatsu-Forda), at one year (old) post planted meranti under A. mangium stands  and spacing of 4 x 2 m, approximately two hectares of permanent  sample plot (PSP) were made. Ineach hectare  of young meranti plants with spacing 10  x 3 m  (330 seedling/ha),  9 (nine) observation plots  with size 10 x 10 m (6 seedlings/plot)  were prepared,  and placed in the middle of PSP. Totally, there were 108 seedlings available for the measurement of particular parameter, i.e. light intensity, height growth, and survival rate. Light intensity  was  measured by going around of 10 x 10 m plot.Result of measurement in each observation plot (10 x 10 m size) rescaled that light intensity ranged about  6,55  - 35,2% or being equal with 4908 - 26568 flux hour. Meanwhile, the best height growth response and survivalrate were at 10 %   light intensity or over.

Abstract

Dendracalamusasper is  one of  the most widely use and widely distributed bamboo  species in Indonesia. A genetic conservation plot has been established to maintain genetic diversity of the species. A total of  115 samples  were collected from 12 sites throughout Java. Genetic diversity was revealed using 31   RAPD  primers  producing  64 polymorphic  bands.  A total  of  81  different  multi-locus genotypes (genets) were identified between 115 samples. TI1e total number of multi-locus genotypes in all populations ranged from 3 to 9 (mean 6.5),  indicating that all populations consisted of multiple genotypes. Mean genetic diversity was 0.04, (ranging from the lowest 0.009 in Kuningan population to the highest 0.144  in Purwokerto population). The Simpsons diversity index indicated  that the most population composed of  unique genotype. Geographical differences did not correlate with genetic cluster.

Abstract

This study was conducted to identify chemical composition of merkus pine resin, rosin and turpentine oil. Initially, pine resin was separated into neutral and acidic fractions with an aqueous 4% sodium hydroxide solution. After methylation, the fraction containing turpentine oil and rosin were analyzed by gas chromatography (GC), and gas chromatograph mass spectrometry (GC-MS), respectively. The neutral fraction of pine resin and turpentine oil mainly consisted of a-pinene, D-3-carene and b-pinene. Based on mass spectral comparison, the major constituents of the acidic fraction and rosin were identified as sandaracopimaric acid, isopimaric acid, palustric acid, dehydroabietic acid, abietic acid, neoabietic acid, and merkusic acid. The major component of the acidic fractions was palustric acid, while that of rosin was abietic acid. Using TC (tough column) 1 and TC 5 columns, levopimaric acid could not be separated from rosin or acidic fraction of pine resin of Indonesian Pinus merkusii.

Abstract

Tropical peat-swamp forests are one of  the largest near-surface reserves of terrestrial organic carbon,  but rnany peat-swamp forest tree species decreased due over-exploitation, forest fire and conversion of natural forests into agricultural lands. Among those species are slow-growing Calophyllum  hoseiand Ploiarium  alternifolium, two species are good for construction of boats, furniture, house building and considerable attention from pharmacological viewpoint for human healthly. This study was aimed at understanding the effects of arbuscular mycorrhizal (AM) fungi on early growth of  C. hosei and P.alternifoliumunder greenhouse condition. Seedlings of C. hosei and P.alternifoliumwere inoculated with AM fungi: Glomus clarum and Glomus aggregatum ,or uninoculated under greenhouse condition during 6 months. AM colonization,   plant growth,  survival rate and  nutrient  content  (P, Zn  and B) were measured. The percentage of C. hoseiand P.alternifolium ranged from 27-32% and 18-19%,  respectively. Both inoculated seedling species had greater plant  height, diameter, leaf number, shoot and root dry weight than control  seedlings.   Nutrient  content  of  inoculated  plants  were increased with AM colonization- Survival rates of  inoculated plants were higher (100%)  than those of  control plants (67%). The results suggested that inoculation of AM fungi could improve the early growth of C. hoseiand P.alternifolium grown in tropical peat-swamp forest therefore  this finding has greater potential impact if this innovative technology applied in field scales which are socially acceptable, commercially profitable and environmentally friendly.

Abstract

Fellingis an early step in timber utilization process. Efficiencyand effectivity of felling technique, tool type and feller posture will affect the whole timber utilization efficiency. This study was carried out at two timber estates in East Kalimantan and intended to see the effect of two felling techniques and feller postures on felling productivity, fellingcost, as well as timber utilization efficiency.Primary  data collected in this research  included :  felling time, volume  of  felled timber, productivity, felling efficiency, stump height and felling cost. The data was analyzed using split-plot design with factorial pattern.The result showed that the implementation of lowest possible felling technique (LPFI) increased log production from 14.4  to 17.7%. The lowest stump height left was of  the one using LPFf  with particular bowed posture in PT. Sumalindo Lestari Jaya I (SLJ I) (4.82 cm).

Abstract

This  study was conducted to provide basic information  on the treatment of some wood species using a copper bichromated boron (CCB).  The specimens  were treated with CCB for 2 hours  in a 150 psi of full cell process.  The treated and untreated wood samples were tested against marine borers for 4, 8 and 12  months.  The results indicated that full cell process with CCB were able  to prevent marine borers  attack. Untreated  wood  specimens were susceptible to marine borers attack, except Iara (Metrosiderospetiolata Kds.) and kandole  (Diploknema oligomera HJ.L.).  The attacking borers  are Martesia striata Linn of the Pholadidae   family, Teredo bartschi Clapp.,  Dicyathifer manni Wright and Bankia  cieba Clench.  of the Teredinidae family. However, crustaceans   were found clinging to the wood specimens when they were taken from the sea. These crustaceans belongs to Sphaeromatidae family.
