Abstract

Suatu percobaan  impregnasi tiga jenis  kayu daun lebar Indonesia dengan bahan pelumas sudah dilaksanakan.  Tujuannya adalah untuk menghasilkan kayu yang memiliki sifat mendekati kayu pok  (Guajacum spp.):   berat jenis  tinggi dan kandungan resin/pelumas tinggi,  cocok untuk penyangga poros baling-baling kapal laut.Tiga jenis  kayu yang diuji yaitu Elateriospermum tapos Bl., Dialium platysepalum  Backer, dan Xanthophyllum stipitatum Benn.  Pemilihan jenis  didasarkan pada hipotesis  bahwa jenis kayu ini mudah diimpregnasi karena mempunyai parenkim pita berjarak rapat.lmpregnasi  dilakukan dengan 4 jenis minyak yaitu: minyak jarak,  minyak kemiri,  minyak laka dan  asam  oleat.   Konsentrasi  minyak yang  digunakan  adalah  3%  dalam  alkohol  lalu diimpregnasikan ke dalam kayu dengan bagan berikut:  vakum awal 500 mmHg selama 15 menit, tekanan hidraulik 10 atm selama 60 menit, dan vakum akhir 500 mmHg seiama 15 menit. Absorpsi  larutan dapat mencapai  62,7% berat kayu pada Elateriospermum, 20,7%   pada Dialium dan 18, 7%  pada kayu Xanthophyllum.   Hal ini menunjukkan bahwa ketiga kayu yang dicoba termasuk sedang-sukar diimpregnasi. Karena iiu disarankan untuk dilakukan percobaan lebih lanjut  dengan  menggunakan  kadar pelumas  yang  lebih tinggi dan jangka waktu tekan yang lebih lama.  Mungkin diperlukan pemanasan pada waktu proses untuk menurunkan kekentalan pelumas yang digunakan.

Abstract

Data collected consist of the diameters and lengths of wood used in railroad construction in swamp forests of ten forest companies in Sumatera, and six in Kalimantan. Railroads in the swamp forests are different in construction compared to those in the teak forests, generally requiring four layers of sleepers.  This, of course, is due to the extremely low bearing capacity of the soil little is known about the problems of this type of railroad construction, primarily with regard to the quantity of wood required.The steps of collecting data were as follow:Selecting suitable forest companies in Sumatera and in Kalimantan to be surveyed.In each forest area 20 samples of 50 m rail track sections were drawn systematically.Diameters and lengths of logs within the sections were measured according to layers.The average amount of wood used in swamp forests railroad in Sumatera and Kalimantan are respectively 142 m3/km and 188 m3/km. The volume of wood used in every km of railroad between regions are significantly different, and those among forest companies very significantly.Wood used in every km of railroad construction and for layer of sleepers vary. The average of wood used for railroad construction of the 1st and 2nd layer in Sumatera are respectively 55 m3  /km and 87 m3/km.  Those in Kalimantan consist of four layers of sleepers, i.e.:   Ist, 2nd,  3rd and 4th layer from the  top-down,  averaging 32 m3lkm, 64 m3/km, 74 m3/km and 18 m3/km of wood used per layer respectively.

Abstract

Macadamia hildebrandii  van Steen,  commonly   known  as makadamia,  belongs to the family  Proteaceae.   Until recently,   this  wood  has not  been  widely  used and only grown sporadically  in several places in Indonesia  mainly  used for non commercial  purposes.   The  wood  material  used  in the.  experiment was obtained  from  Sipangan Bolon,   North  Sumatra  for both  pulping   trials and  chemical  analyses.The  chemical  constituents   of  the  wood  are typically  of  those  tropical  wood  containing  46.6%  cellulose, 24.6% of lignin, and  relatively  low  14.4% pentosan. The average specific gravity  was 0.61 and the fibre length of  1.76 mm. The pulping  experiment was  conducted   in laboratory  digester employing 20% active alkali, 170°C  maximum temperature wich was maintained  for 120 minutes.  The cooking  sulfidity   was made at 2 levels i.e. 25%  and 30%.The makadamia pulp  yield  ranged from  32.4 to 34. 7% with  low Permangante  number  2.15   to 2. 64. The pulp  strength was fair and comparable  to those of the commercial  types.  By adding of anthraquinone   catalyst  at 0,1percent  by weight of the  wood  material  to cooking,   a  significant  improvement   in pulp  strength   was commenced. This is particular noticed when using 25% sulfidity  during the pulping.
