Abstract

The utilization of black liquor produced in pulp and paper production has been limited for adbesive. In microbiology, black liquor can be used as a selective mediunt. The purpose of this study was to evaluate the performacne of lignin isolated from black liquor of biopulping process as a selective medium for white-rot fungi. Lignin, from black Liquor of soda and kraft pulping of bamboo petung was isolated by acid addition. Lignin solid was then purified using diccan solution, weighted and qualitatively analyzed using a spectrophotometer. The isolated lignin was added to agar media to test the white-rot fungi selectivity (Phanerochazte crysosporium and Trametes versicolor). The results showed that pretreatment of bamboo for 30 days give more lignin than the 45-days treated bambon. Lignin solid from kraft process was also bigher than lignin from soda process. Enzyme secretion from fungi T. versicolor occurs more rapidly than P. chrysasporium on selective media alkali-lignin.

Abstract

Research on natural medicinal plants has been growing due to the increasing interest to natural medicinal material that is considered safer than synthetic medicines. In North Sumatera, bark of Cotylelobium sp which is locally known as raru, bas been widely utilized by the local community. The skin bark of this species is commonly used as a mixture of "nira" to produce "tuak" (Batak's traditional alcoholic liquor). In addition, local community has been using this species for traditional bealing as well. This research is to study the potency of raru's skin bark in producing anticocidant using DPHH method. The taxicity activity of the material was also examined using Brine Shrimp Lethality Test (BSLT) method. Results show that the yield extract of Cotylelobium melanocylon Pierre was 30.11% and Cotylelobium lanceolatum Craib was 14.50%. Both extracts contains flavonoid, tanin, saponin, triterpenoid and bidroquinon. The extract of Cotylelobium melanocylon Pierre has antioxidant activity against DPPH radical with value of IG as mus as 108.487 ppm and 77.909 ppm for Cotylelobium lanceolatum Craib. Furthermore, the toxicity of Cotylelobium melanoxylon Pierre was 643.550 ppm and Cotylelobium lanceolatum Craib was 767.191 ppm LC

Abstract

In the situation of wood material shortage, it is important to furniture manufacturers to efficiently utilize the wood. Increasing efficiency for improving value added of small medium enterprises of wood furniture industries in Jepara should be carried out from the first stage in wood processing: sawing that will convert logs into sawn timber. A study has been carried out on improving sawing recovery of sawntimber by live-sawing pattern to make loseware lumber for furniture material in Jepara region. This study was done by investigating the current sawing recovery data as determined during one full day's processing at each of the four bandsaw mill facilities and one chainsaw/carving facility. The results indicate that the current recovery rate of sawmilling services companies in Jepara reached 70-80%. These recoveries are relatively high due to the live sawing pattern used and the fact that sawn boards were not edged or resawn into square pieces at the mill. Compared to existing rules and the Government standard for calculating the recovery rate, sawmilling service companies in Jepara have practiced efficient processing in sawing.

Abstract

The role of forests as carbon sink and carbon store is undoubtedly important to reduce the carbon amount in the earth atmosphere thereby preventing greenbouse (GHG) effect that can induer the global warming. Among the varisar types of forest, peat swamp forest serves as the largest carbon store. A research bas been carried out at the fiber wond plantation forest comprising mostly Acacia crassicarpa species that grew on a peat land, at the Pelalawan sector, Rian Province. The research was to obtain allometric equatios that related the growth parameters of A. crassicarpa trees (Le tree diameter (D) and height either a total (tot) or branch free (Hbc)) to their growth products Le.biomess (W) and carbon mass (C). It was found that the best fitted and must representative allometric equations were consecutively IF= 0.398918D Hix (for estimating biomass patency) and C = 0.131D Htol""" (for carbon mass potency) Fartbremore, samples A. Crassicarpa tree from different stand ages (2,3,4, and 5 years old) covering particular free portions (Le main stems, branches, twigs, leaves, and roots) were tested for moisture contents, specific growity/density, ash content, volatile matter and fisced carbon. The allometric equations obtained were used to measure and estimate the biomass and carbon mass potencies of A. crassicarpa tree stands at their age group, iz. 2,3,4 and 5 years old Using those allometric equations, the estimates of biomass (W) of A. Crassicarpa for age 2, 3, 4 and 5 years old are 44.98 tons/ha, 70.35 tons/ha, 134.05 tons/ba, and 234.78 tons/year. The potency of carbon mass are 12.09 tons/ha, 36.23 tons/ha, 76.09 tons/ha and 133.10 tons/ha, for stand age 2,3,4 and 5 respectively.

Abstract

Pulai (Alstonia sp.) belonging to the family Apocynaceae, produces latex which is frequently used as a traditional medicine. Various literatures on medicinal tree species frequently mention about it, but a description of the wood and bark anatomy of pulai up to the species level is hardly found. Anatomical structure of wood and bark of Alstonia scholaris, A. angustiloba and A. pneumatophora were observed on samples produced using a microtome. Dimensions of wood fiber and vessel cells also were measured. Observations showed that the three species of pulai wood can be distinguished from the differences in diameter and frequency of vessel cells, type and arrangement of parenchyma cells, width and composition of the ray cells. The bark of these species can be distinguisbed based on the form of sklereid cells and the presence of dilationed ray cells (widening ray cell).

Abstract

Implementation reduced impact logging (RIL) technique in peatlands may contribute optimum and sustainable yield. A study was carried out at concession area of Kalimantan Subur Permai Company, West Kalimantan. The area war a natural peat swamp forest set aside for the land-clearing in preparation for the establishment of industrial plantation forest, in which consisted of miced barkwood trees. This study examined possibility of increasing productivy, decreasing logging cast, subsidence, and water fluctuation using RIL. technique. Results revealed that the use of RIL in felling, skidding, loading, un-loading, and banling at peat swamp forest could: 1. Increase productivity for each activity of consecutively 0,946 m²/hour, 2,449 m² / Бомт, 1,96 m²/bour, 1,871 m²/hour, and 2,158 ml/bour, 2. Decreased production cost of Rp 992,1/m², Rp 3.088,6/, Rp 127,9/m², Rp 99,7/m², and Rp 158,6/m² consecutively; 3. Inceased timber efficiency utilization (TUE) about 6% equal to Rp 74,400,000/year, 4. Subridence proceeded at 0.375 om/year rate, which corresponded to 1.875 cm in five years. This figure was still lower than that stipulated in the Indonesia's Government Decree (PP) Na. 150-2000. 4. The averages of water level at logging site and canal were 61.75 cm and 52.25 cm, respectively.

Abstract

This study aimed to examine the resistance of composite boards made of sago frond using polyurethane (PU) and phenol formaldehyde (PF) adhesives against rotting fungi and termite. Dimension and targeted density of composite board were 30 cm × 30 cm × 1 cm and 0.5 g cm⁻³, respectively. Composite boards were prepared by cold press machine for composite boards using PU resin as a binder and hot press machine for boards using PF resin under the following conditions: 25 kg cm⁻² for 24 hours in cold pressing process and 10 minutes in hot pressing process with 140°C of temperature. Solid content of liquid adhesives was 50% with resin content as variations in this study i.e. 10%, 12% and 14%. The boards were tested against JIS K 1571 2004. The results show the composite boards treated with PU and PF adhesives were not resistant to rotting fungi and termites.

Abstract

Mata kucing dammar has long become remarkable export commodity, most of which unfortunately is still in naturalform (chunk-shapped exudates) obtained from the tapping of its host trees (Shorea javanica). Accordingly, such dammarstill contains large amount of impurities thereby lowering its qualities or trade values. Consequently, this necessitates athorough purification attempt to enhance the dammar's added-value. The dammar purification prevalently uses organicsolvent. However, the market demand for the solvent-free dammar products currently tends to increase commensurate withthe advancement in dammar usage for drugs/ medicine and food industries. In relevant, purification of mata-kucingdammar was experimented using manual heating system, rather than organic solvent. Result revealed physico-chemicalproperties of the heat-purified dammar were not significantly different from those of natural dammar (without purificationtreatment) as well as of the solvent-purified dammar. Even, with respect to ash content (impurities) and toluene insolubility,the heat-purified dammar seemed to be better than the natural dammar. GC-MS analysis revealed there were five majorchemical compounds with relatively large contents in heat-purified dammar. Such phenomena were similar to those in thenatural dammar, with the contents of those compounds in the heat-purified dammar slightly higher.

Abstract

Skidding, maintenance and canal establisment activities in peat swamp forest require comprehensive planning actionssince the forest has a critical land and difficult to reclamate when it is damaged seriously. It is required to determine anoptimum felling area, considering technical, economical and ecological aspects. A study was carried out in June 2013 atconcession area of Bina Silva Nusa (PT BSN) Company. This study aimed to find out the optimum felling area and theskidding productivity, as well as canal maintenance and establishment. Data were taken descriptively and purposively,which comprised of felling-plot areas (Y) and the costs (X) for skidding, maintenance, and canal establishment. Further,the obtained X-Y data couples were analyzed for possible quadratic regression models. This study resulted model of theoptimum felling area : 1. Y = 55.7 - 6.8 X + 0.21 X ; or Ln Y = 55.7 - 6.8 Ln X + 0.21 Ln X , whichR = 0.1532** or R = 0.391 (R = 0.254), with the optimum felling area (Y ) of 22.21 ha and the minimumcost (X ) as much as Rp 612.644.033; 2. The average increase of skidding productivity andestablishment/maintenance of the secondary canal, collector canal and tertiery canal were 1.37 m /hour (9.5%), 1.298m/hour (5.3%), 1.706 m/hour (2.33%), and 1.4 m/hour (1.3%).

Abstract

Fungal resistance of five wood species from Ciamis: langkaled (Litsea roxburghii Hassk.), cangkring (Erythrina fusca Lour.), kayu putih (Melaleuca cajuputi Powell), ki tanab (Zanthoxylum rhetsa D.C.), and burun leueur (Sterculia cordata Blume), was observed using Kolle-Halls method. Wood samples of inner and outer parts of the log were prepared from three trees of every species. Wood samples were tested against eleven strain of decaying fungi. The results show that langkaled and ki tanab woods are classified as resistant (class III), while cangkring, kayu putih and burun leueur woods fall into not-resistant (class IV). In general, the weight loss of samples taken from outer part is greater than those taken from the inner part of the log. It indicates that wood samples taken from outer part (not resistant, class IV) is less resistance than the inner part (moderately resistant, class III). There were also resistant variations between trees. In those five wood species, for example, the first tree (P-I) belong to class III, however the second and third tree (P-II and P-III) falls in to class IV. The highest weight loss was recorded in a wood sample of P-I of cangkring, which was exposed into Pycnoporus sanguineus HHBI-324. The wood fungi decaying capability from the highest to the lowest are P. sanguineus HHBI-324, P. sanguineus HHBI-348, Polyporus sp. HHBI-209, Trametes sp., Polyporus sp. HHBI-371, Schizophyllum commune, Chaetomium globosum, P. sanguineus HHBI-345, P. sanguineus HHBI-8149, Xylaria spinosis, and Dacryporus spathularia.
