Abstract

This study was designed to determine the ability of six commercial exterior finishes (2 clear coats and 4 opaque coats) in protecting wood from dimensional changes. Two wood species, jabon (Anthocephalus cadamba Miq.) and mangium (Acacia mangium Willd.) were used in this study. Samples were seasoned to air-dry condition (moisture content of 15-17%) and then divided into groups on the basis of treatments and grain orientation (radial and tangential). Application of each exterior finish was undertaken according to procedures suggested by the finish manufacturer. The effectiveness of treatments to dimensionally stabilize wood was determined by measurements of wood swelling within 72-hours immersion and calculation of anti-swelling efficiency (ASE). Results of observations made to this stage showed that the effect of finishing on wood dimensional stability varied according to wood species, grain orientation and type offinish coat. Finishing had a greater dimensional stabilizing effect on jabon than mangium. Reduction of swelling due to finishing was greater in tangential compared to radial boards. The use of clear coats significantly gave less protection on wood stability than that of opaque coats. Anti-swelling efficiency of all treatments markedly decreased with increasing period of immersion.

Abstract

Garcinia cowa termasuk famili Guttiferae, yang dikenal di Indonesia dengan nama asam kandis. Secara tradisional kulit batang Garcinia cowa telah digunakan sebagai antipiretik dan antimikroba, sementara buah dan daunnya untuk memperlancar peredaran darah, ekspektoran, pencahar, serta akarnya untuk menurunkan demam. Keragaman manfaat tumbuhan Garcinia sebagai obat tradisional tersebut terkait dengan kandungan kimianya. Dalam rangka investigasi berkelanjutan untuk mencari senyawa metabolit sekunder dari tumbuhan genus Garcinia asal Indonesia, suatu senyawa steroid, stigmasterol telah berhasil diisolasi dari bagian akar Garcinia cowa. Isolasi dilakukan dengan cara ekstraksi dan berbagai metode kromatografi. Penentuan struktur senyawa stigmasterol l berdasarkan data spektroskopi NMR dan dengan membandingkan data senyawa yang diperoleh dengan literatur. Berdasarkan analisa spektroskopi disimpulkan senyawa hasil isolasi adalah stigmasterol. Senyawa ini baru dilaporkan dari spesies ini.

Abstract

An investigation on productivity and log­skidding cost using buffalo (Bubalus bubalis) was carried out at the area of lnhutani V in Jambi in 1999. The objective is to get reliable information about such productivity and cost. Connected with this purpose, some related data as collected were i.e. volume of skidded log, skidding distance, skidding­working time, buffalo working time, feeding cost, operator cost, and equipment.Volumes of log which was skidded using buffalo ranged between 0.094 and 0.904 m3/tripwith an avverage of 0.484 m3/trip. Skidding distance using buffalo varied from 10 to 2­12 m with an average of 82 m. The working time varied from 11 to 83 minutes with an average of 30 minutes. The log skidding productivity ranged between 0.035 and 1.211 m3­hm/hour with an average of 0.338 m3­hmlhour. Log skidding costs using buffalo ranged between Rp 681 and Rp23.589 m3­hm with an average of Rp 4.375/m3­hm. It is suggested that volume of skidded log in each round trip and skidding distance be not more than 1 m3 and 250 m, respectively.

Abstract

This paper   describes  the  treatment  of  1.5  mm   x  20  cm x  20 cm rubberwood  veneer  with BFCA compound of   5 %,  10%.   15 %, 20 %  and  control,  and  3  variations of  extender  in urea  formaldehyde   glue  ,    compositionic    10%, 20% and 30%.The  results  reveal   that  the   concentration of  BFCA  influences    the  bonding   strength  of  rubberwood plywood using Indonesian standard. On the  other  hand  the  effect of percentage   of  extender in  tne compostion  of  urea  formal dehyde   glue  is  not  significant on the bonding strength using Indonesian and Japanese standard. But  the interaction. of concentration of BFCA and percentage  of  extender influences  the bonding strength of plywood.

Abstract

Wood samples  of three species measuring .3 cm x  3 cm x 3 cm (150 samples for each species) were treated with cold soaking treatment using borax and boric acid preservatives for 1,3,5,  7, and 9 days at the concentrations of 2,3, and 5 percent.The test result of experiment, after taking both retention and penetration  requirements into consideration for wood used under roof without ground contact showed that only  two species,  damar kunyit and pulai, could be satisfactorily treated with Boric Acid under the experimental  conditions,   while other species,  benuang,  couldn't  meet the standard.  Borax preservative  showed  a good result only on one species.  i.e.  pulai.For under roof usage without ground contact, pulai can be consecutively soaked for 9 and 7 days in boric acid solution of 3 and 5 percent, while in borax, for 5 and 3 days soaking  time are 3 and 5 percent. Damar kunyit used under roof without ground contact could be soaked for 7 days in boric acid solution of 5 percent.

Abstract

Getah jelutung diperoleh dari pohon jelutung (Dyera lowii) dan merupakan komoditas ekspor. Penelitian yang dilakukan di Palangkaraya, Kalimantan Tengah bertujuan untuk mengetahui pengaruh lingkaran pohon dan lebar torehan terhadap getah jelutung yang dihasilkan. Jumlah pohon yang diamati dalam penelitian ini sehanvakt 60 batang dengan parameter yang diamati adalah lingkaran pohon (X1), lebar torehan (X2) serta getah yang dihasilkan (Y). Data dianalisis dengan menggunakan regresi linear ganda.Hasil penelitian menunjukkan bahwa baik lingkaran pohon jelutung maupun lebar torehan memberikan pengaruh yang nyata secara positif terhadap hasil getah. menurut persamaan regresi berganda (dalam bentuk transformasi ln ) yaitu Ln Y = 4.45 + 0.0102 X1 + 0.00628 X2. Hal ini berarti hasil getah dapat diduga dari lingkaran pohon dan lebar torehan.

Abstract

Eight  wood  species from  forest  experimental   garden in West Java were observed  for identification purposes.  All  wood species  could  be  identified one  from  the  others,  due  to  their  distinguished   conspicuous   characters. Kecapi  (Sandoricum kucape   Merr.)  on  the  other  hand,   showed   characters  that  matched   only   the  previous   description   of  the  genus.  Such characters,  were apparently not  sufficed to describe  the species.
