Abstract

This study examines wood properties as the indicator of waru gunung wood quality based on age and axialdirectionand their implication on drying quality. Wood samples used in this study collected from three ages, i.e. 8, 12, and16years.Thesamples were arranged in axial direction of the tree stem,namely, bottom, middle, and top portions. The basicproperties of the wood observed i.e. fiber length, specific gravity (SG), and wood shrinkages for each axial portions wereobserved in radial direction from near pith, central and near bark. Fiber length measurements were undergoneusingprocedure practiced at the Centerfor Research and Development on Forestry Engineering and Forest ProductsProcessingBogor. Specific gravity and shrinkage were determined in accordance with the modified ASTM D143-94, meanwhiledrying properties and qualitieswere observed using the modified Terazawa method.Results revealed that thefiber length and SG of waru gunung were affected by tree ages, andposition of the tree stemin both axialand radial directions. Considering basic propertiesand dryingqualities of the series wood aging, itturned out that wood with tree age of 16 years could comply with the requirementsforfurniture material.

Abstract

Agarwood signifies as one of the non-timber forest products (NIFPs) comodities in Indonesia. The form of agarwood varies, such as lumps, chips, flour, until oil. Agarwood in incense shape will give off smells, if burnt. This experiment aimed to identify chemical components in four grades of agarwood from the best to the lowest i.e. kacangan B, teri B, kamedangan A dan kamedangan B. Identification was performed by extracting the agarwood with acetone solvent, and then the acetone extract was fractionated using gradient column chromatography method with n-bexane-ethyl acetate as eluent. Identification of compounds proceeded using gas chromatography-mass spectrophotometer Results of identification revealed that there were sesquiterpene compounds in the four grades of agarwood (i.e. kacangan B, teri B, kamedangan A and kamedangan B), but kinds of compounds were different from one grade to other. Chromone compounds only existed in 2 grades of agarwood covering kacangan B ubich bad 2 compounds (6-bidroxy-2-methyl-5-nitrochromone), and 3-metaxxymethyl-2,5,5,8a-tetramethyl-6,7,8,8a-tetrabydro-5H-chromone), and kamedangan A with only one compound (2,2-dimethyl-6,7-dimetawcychromone). The presence of sesquiterpene and chromone with particular portion and characteristic in each of those four agarwood grades indicatively bears their role explaining their grades from the best until the lowest.

Abstract

Stump wastes of the felled tree Acacia crassicarpa are not yet used although they are available in large quantity. Converting the stump into actived charcoal maybe one of the most possible uses of the treestump. This experiment investigates the properties of actived charcoal made from Acacia crassicarpa treestump. The treestump was carbonized into charesal, then activated by immersing in H,PO, solution with concentration of 5% and 10% for 90 minutes. The treated charcoal was then beated in retort at various temperatures of 650C, 750°C and 850C. The result showed that good quality of activated charcoal was obtained by using 10% H,PO, at temperature 750 C. The yield of the activated charcoal at this condition was 57%, water content 0,49%, volatile matter 7,37%, ash content 4,22%, fixed carbon 88,41%, adsorptive capacity of indine 1115,5 mg/g, adsorptive capacity of benzene 25,52%, adsorptive capacity of cloroform 41,29% and adsorptive capacity of formaldebyde 45,91%. These characteristics met the SNI requirements and the charenal can be used for water purification. It can increase pH of water from 5,63 to 6,9 and reduce metals Fe and Zn respectively from 0,600 and 0,037 mg/L. into 0,424 and 0,024 mg/1. The structure of charcoal is more reguler after activation.

Abstract

Illipe nut in Indonesia still serves as one of the essential export commodities from the group of non-wood forest products. These nuts unfortunately are traded only in form of the dried fruits. Attempts are necessary to enhance the added value of illipe nuts. Among them is through the processing of the fruit into fat. One manner to extract the fat portion from the illipe- nut fruits is using organic solvent. In relevant, research was conducted on the extraction of illipe-nut fat from its fruit of 4 specier Shorea spp which was originated from the experiment station in Bogor, West Java. Fat extraction was conducted using bexane as the sohvent. The resulting fat was then examined for it physical-chemical properties and sustained the GC- MS (Gas Chromathography-Mass Spectrometry) analysis. The result revealed that the illipe-nut fat from 4 tree species varied in fat yield and its physical-chemical properties (Le. moisture content, acid number, free fatic acid and ind number). The GC-MS analysis indicated that illipe-nut fat contained various saturated fatty acid as well as unsaturated and other chemical compounds, such as phenol, aldebryde, bydrocarbon (aliphatic and cyclic) and hexane (presumably from the organic solvent). Oleic acid is dominant chemical component of S. stenoptera and S. parvifolia, metbyl oleate in S. pinanga and methylene-(4-trimethylsilanyl-phenyl)-amine in S. mecisopteryx.

Abstract

The objective of this research is to study the effectiveness of semi mechanical control of Acacia nilotica (L) Willd. Ex. Del using tirfor in Baluran National Park in 2009. The results showed that the 75 trees were trunked using tirfor but 15 tree maually. The average productivity of each was 3,59 trees per hour and 0,5 trees per boar. The averages operational cost were Rp 5,277/ trees and Rp 16,666/trees. The soil bas been displaced with an average rate of 1%/ m per trees and 6,252 / mi per trees for semi mechanic and manual. Respectively the volume of 1,5587 m has been produced from 75.A. nilotica lry using tirfor and 0,3 m from manually. All of wood produced bas not been utilized yet.
