Abstract

The  result  of  a  study   on  the  susceptibility    of  rattan  to  fungal  attack.   Three  rattan  species  i.e.   irit (Calamus  trachy- coleus  Becc.),   manau  (C.  manan  Miq.)  and  semambu   (C. scipionum Lour.)   both peeled  and  unpeeled  were kept  out  door. Fungal  infestation   was than  observed  after  one,  two,   four  and  eight  week  periods.  At  the end of experiment,   each rattan sample  was split  into  two  halves to observe  internal  discoloration.   The result showes  that  irit was most  susceptible   to stain attack   and  infestation   on peeled  cane seems  to  be more  severe  compared   with  unpeeled  ones.  The  average rate of  infes- tation  of  the  rattan  species  studied was  10.59   % (4.65  -   14,92  %) per  week.   The  lowest  and  highest  rate of  infestation were shown  respectively   by  unpeeled  manau and peeled  irit rattan.  It was also revealed  that  93.33  % of  the  test speciments were  internally  stained,   of  which  46.67  % were badly stained.  Semambu  rattan seems  to  beresistant  to fungal  infestation, most  of  which showing  low degree  of  internal stain.

Abstract

Biodiesel adalah senyawa alkil ester yang dapat digunakan sebagai bahan bakar untuk mesin diesel, berasal dari turunan minyak atau lemak nabati/hewani. Minyak kesambi merupakan salah satu sumber bahan baku yang diduga dapat dijadikan biodiesel, karena kandungan asam-asam lemaknya tidak jauh berbeda dengan kandungan dari minyak nabati lainnya yang sudah terbukti bisa dijadikan biodiesel. Proses produksi biodiesel umumnya melalui reaksi esterifikasi, transesterifikasi. Penelitian ini bertujuan untuk mengetahui pengaruh perlakuan proses terhadap kualitas biodiesel yang dihasilkan. Dalam penelitian ini dicoba memvariasikan faktor tahapan proses, jumlah metanol yang digunakan dan waktu esterifikasi. Pada penelitian utama digunakan rancangan percobaan acak lengkap faktorial dengan tiga faktor yaitu tahapan reaksi, jumlah metanol dan waktu esterifikasi. Faktor tahapan reaksi terdiri dari empat taraf yang terdiri dari kombinasi esterifikasi (E), transesterifikasi (T) dan netralisasi (N). Empat taraf untuk tahapan proses yaitu esterifikasi- transesterifikasi (ET), esterifikasi-esterifikasi-trans-esterifikasi (EET), esterifikasi-netralisasi- transesterifikasi (ENT) dan esterifikasi-transesterifikasi-netralisasi (ETN). Faktor jumlah metanol terdiri atas dua taraf yaitu penggunaan nisbah molar metanol-minyak dengan perbandingan 15:1 dan 20:1. Untuk waktu esterifikasi juga terdiri atas dua taraf, 30 menit dan 60 menit. Biodiesel yang diperoleh kemudian dianalisis. Analisis yang dilakukan meliputi analisis bilangan asam, kadar air, rendemen, viskositas dan densitas. Hasil analisis sifat fisikokimia biodiesel menunjukkan kadar air 0,10 - 0,82%. Bilangan asam biodiesel yang diperoleh antara 0,625 - 1,330 mg KOH/g minyak, viskositas kinematik 12,70 - 16,40 cSt, densitas 0,906 - 0,920 g/cm3dan rendemen biodiesel setelah deguming 63,01- 96,93%. Proses ENT merupakan proses terbaik dibandingkan dengan proses lainnya.

Abstract

Fifty two Indonesian wood species were collected from forest areas in Indonesia for durability test. The samples measuring 60 cm (in length) by 5 cm (width) by 5 cm (height) were prepared. The durability's field test was conducted at Cikampek experimental forest using a graveyard method. The samples were vertically but partially buried lengthwise in the soil, leaving behind 10 cm upright still exposed to the air. The spaces (distances) between the buried samples were 15 cm. Assessment on the buried samples (stacks) was carried out once after the succession of each 6-month interval. The assessment involved the degrees of attack by termites and the depth (extent) of decay inflicted by particular fungi. Afterwards, the 52 wood species as each represented by their tested stacks/samples could be categorized into five durability classes. Most of the samples were severely attacked by termites. Forty nine out of 52 wood species (i.e. 94 percent) were attacked by termites. Meanwhile, the remaining 3 wood species (Glochindion philippicum Robins., Blumeodendron kurzii J.J. S.M. and Myristica lognifes Ward.) were attacked by the decaying fungi. Therefore, those three species were categorized as durability class V. In total, there were 33 wood species (63,4 percent) that belonged to durability class V, 17 wood species (32,6 percent) as class IV and 2 wood species (3,8 percent) as class III. Since none can be categorized as durability class I or II. the preservative treatment is necessary for the overall 52 wood species. The species categorized as durability class III were rengas manuk (Gluta wallichii (Hook f Ding Hou) and kempas (Koompasia malaccensis Maing.).

Abstract

This experiment is intended to improve the quality of the several types of benzoin by using an aceton solvent. The benzoin consisted of four samples with decreasing order of  quality: "mata kasar",   "mata halus", "jurur" and "abu". All of  these  samples  were obtained from Tarutung North Sumatera. A general linear models procedure in the SAS computer package was employed to analyze the effect of the acetone solvent extraction and benzoin quality on physico chemical properties of benzoin.Results showed that the acetone solvent extraction. type of benzoin and the interaction of both gave a highly significant effect on moisture contens. Softening points, number of saponifications, solubility in ethanol. ash contents.  benzoin acid, calculated as cinnamic acids; except the effect of interaction  on softening  points. Furthermore,  the LSD analysis between means indicated that there were significant  differences  on physico  - chemical properties  among the type of benzoin, exclude the means value of solubility in alcohol between "mata kasar" and "mata halus".  and between "jurur" and "abu". There was also no significant difference on an ash content means value between "mata kasar" and "mata halus".  This aceton solvent extraction increased tire quality of "mata kasar" and "mata halus" benzoin to meet the first and tire second quality requirement of the Indonesian National Standard.  respectively. However,  the softening point of jurur benzoin did not meet second quality requirement of this standard. Overall,  the aceton solvent extraction can improve the quality of benzoin as indicated by an increase  in benzoin value, calculated as cinnamic acids, and a decrease in dirt content value.

Abstract

A study on volume and classification of logging waste has been carried out in several forest companies in Aceh, North Sumatra, and East Kalimantan.  Average wood waste volume at the logged over areas having diameter range from  10 to 39  cm with one meter in length or more were measured using the Brereton method.The results of this investigation reveal that:I. Logging waste volume in Aceh range from 26,46  to 29,08  m3/ha  with an average of 27,85  m3/ha.  In North Sumatra the value ranges from 22,94  to 38,66  m3/ha  with an average of 28,90  m3/ha.  It  was formed  that in East Kalimantan  the logging waste ranges from22,00  to 81,94 m3/ha with an average of 52,38 m3/ha.2. The average wood waste at felling site was higher in the forest companies in East Kalimantan.3. Logging waste consists predominantly of those classified as 10 to 39 cm in diameter with 4 m length or more.4. The average volume of logging waste classifiedas 10 to 19 cm in diameter with 4 m length of more in Aceh, North Sumatra and East Kalimantan are consecutively 17,5 m3/ha,16,9 m3/ha and 24,9 m3/ha.

Abstract

Measuring the volume of logs which have been rafted on the rivers is very difficult. The difficulty is mostly in measuring the average top and bottom diameters of logs because the largest portion of logs are inside the water.In this paper, the results of measurements carried out both on the ground and in the river are described. Lately, log measurement in the river is necessary because:a. Volume of logs sent to industries would be measured in the river.b. Many logs of the illegal cutting found are rafted in the river.The observation reveals that :1. Volumes of logs measured on the ground and in the river are significantly different.2. From the sample of 60 logs of Dryobalanops spp. it is found that the total volume measured on the ground is 273,18 m3, while the total volume measured in the river is 262, 76 m3. The total difference is 10,42 m3 or 0,04 m3 per_m3 in average.3. the correction factor (FK) then is 0,04 m3 per m3 or 3,81 %. It means that the volume of log measured in the river is smaller than the volume Measured on the ground. Therefore, the volume measured in the river should be multiplied with the correction factor of 1.04 to obtain the real volume as measured on the ground.

Abstract

One  of  the  products   that  can  be produced   from  secondary  process  of plywood  is fancy  plywood.  The product   is usually  constructed by  overlaying  plywood   with  fancy   veneer  or  other   material  with  nice  decorative  appearance.   This process  will add extra  value to  the final product   intern of selling price as compared  with  ordinary plywood.  In this study fancy. plywood   is constructed   by  overlaying plywood  with  fancy  veneer of  jati,   mahoni  and  rengas.Added  value of fancy plywood  (from plywood)in  three ply mills in North Sumatra  amounted   to Rp.1,032,749,600 in one  year resulted  from 5141 cu.m of  plywood. The  value  is accounted   for  production  factors  with   the  following proportion: 17.73 % from depreciation   factor, 21.94 % from  labour  cost,  and  60.33  % from  profit, taxes,  and  others. The employment created  by  each factory is 48  workers  which  are  equal to 13,920  man days  per year.
