Abstract

Potensi kayu berdiameter kecil (<10cm) dari hutan tanaman cukup besar namun belum dimanfaatkan secara optimal. Sesungguhnya kayu tersebut dapat digunakan sebagai bahan baku pembuatan papan isolasi. Pada penelitian ini menggunakan kayu mangium (Acacia mangium) berdiameter kecil untuk dijadikan pulp, kemudian digunakan dalam pembuatan papan isolasi. Selanjutnya guna meningkatkan fungsi dari papan tersebut, tidak hanya sebagai insulation juga sebagai penyerap gas/uap, maka sebelum dibentuk lembaran papan, pulp mangium dicampur terlebih dahulu dengan arang serat (hasil pengarangan serat kayu mangium dan karet) pada beberapa komposisi yaitu 100:0, 90:10, 80:20 and 70:30 (w/w). Pulp mangium dibuat dengan proses soda panas terbuka. Kualitas papan isolasi yang dibuat telah memenuhi standar Jepang kecuali untuk pengembangan tebalnya. Berdasarkan nilai scoring, kerapatan, dan sifat fisik-mekanik papan isolasi serta dibandingkan dengan standar Jepang maka papan isolasi yang optimal diperoleh pada kontrol dan komposisi pulp dan arang 90:10. Sifat-sifat tersebut mengindikasikan bahwa kayu mangium berdiamater kecil dapat dibuat papan isolasi dengan kualitas yang baik.

Abstract

Porang (Amorphophallus muelleri Blume) adalah salah satu jenis hasil hutan bukan kayu (HHBK) yang memiliki berbagai keunggulan dibandingkan dengan tanaman pangan lainnya. Dari aspek budidaya dan kandungan tepungnya, tepung porang menjadi salah satu sumber pangan alternatif. Saat ini, peningkatan kadar glucomannan menjadi tantangan dalam pengolahan pasca panen porang. Peningkatan kadar glukomanan akan meningkatkan pemanfaatan tepung porang dan membuka pasar tepung porang. Penelitian ini bertujuan untuk mendapatkan teknik pemurnian glukomanan yang optimal. Penelitian dilakukan dengan teknik perendaman dengan etanol (30%, 40%, dan 50%) dan natrium bisulfit (2%, 3%, dan 4%). Hasil penelitian menunjukkan bahwa teknik perendaman dengan etanol berpengaruh nyata terhadap peningkatan kadar glukomanan. Pencucian dengan etanol 50% dan NaHSO3 2% dapat meningkatkan glukomanan dari 32,65% menjadi 83,96%. Proses perendaman dengan etanol meningkatkan kadar glukomanan tetapi tidak mempengaruhi kandungan zat besi (Fe) dan kalsium (Ca) tepung porang.

Abstract

Rattan for the furniture  raw materials is easily attacked by stain fungi and moulds during air  drying, leaving discolored  surfaces.  The soft portion is also susceptible to attack of powder post beetles. To prevent this problem, the newly cut rattan should be  treated with preservative to ensure  a reasonable service life. The treatment   method affects the extent of penetration and absorption of  preservation  into the rattan. The rasult of study  on the preservation  of rattan by pressure process is presented  in this paper. A  pressure   period for 5, 15, and 25  minutas  was sufficient  to obtain required retention of preservative for the rattan tabu-tabu, batang and tohiti.

Abstract

This  article  describes   the  experiment  of  sugar and  alcohol  contents from 3  wood  species,  i.e. jelutung (Dyera costulata, Hook. F), keruing (Dipterocarpus  appendiculatus, Sheff) and  durian  (Durio excelsus, Bakb) by using hydrolysis and  fermentation process. Treatment condition for  hydrolysis  were at 3 levels of sulfuric acid concentration which were 1%, 2%, and 3%  respectively. The fermentation methods agent for producing alcohol  from  sugar of wood  hydrolysis  was the yeast  of  bread containing  Saccharomyces cereviceae.The  result  of this experiment indicated  that  the yield  of sugar ranges from  9.71 % -   11.89% with average of 1,06%. This average yield  of  sugar falls in  the  range of  the  sugar yield  obtained from other researches which have  range from 11-18%.                                                                                                                                                                                                    The  average alcohol  yield  obtained  from  sugar fermentation  was 2.62%. This yield  was lower compared  with other experiment   producing   alcohol  from  wood  abroad, i.e. 8 -   15%. The  result  showed  that  the yield  of sugar is not affected by  the  wood  species  and  low  concentration  of  sulfuric acid  treatment.

Abstract

Physical deformation such as checks or cracks is commonly encountered in the process of drying wood statues.  In the senses of economic and quality improvement, such a case has long been a serious handicap to the Balinese crofters.  A number of trials have been made through modification of drying schedules, but these gave  little protection agents check/crack development, particularly for the medium  to  large size  statues. The  use of polyethylene glycol  (PEG-1000) has significantly  reduced  the  rate  of physical deformation, however, it raised another problem  in finishing and could promote a surface  discoloration. This study  examined another approach of cracking prevention by application of coating treatments to the end grain of wood structure.Fresh  logs of  two  wood species,  i.e., sengon  (Paraserianthes  falcataria  {L.)  Nielsen.)  and  mindi  (Melia azedarach  L.)  were crosscut to 50 cm long specimens,  and then shaped into a simple cat-form statues sizing of approximately  21 cm  wide and 46 cm long. End coatings were applied separately using 4 different materials, i.e., resorcinol formaldehyde, polyvinyl acetate, wood filler and cement.  All treatments were accomplished approximately 30 minutes prior to oven drying, Physical deformation of wood statues was de/ermined  by measuring the width,  length and gap-size of cracks using a digital caliper. The related physical characteristics, such as moisture content and specific: gravity of each species were also determined.Sengon  had a lower  specific: gravity, but a  greater  green  moisture  content  and  dry-ability  than  mindi. Wood physical deformation of both treated and untreated sengon was obviously greater than mindi.   The effectiveness of end coating treatments in reducing  wood cracks  varied according  to  wood species  and the coating materials.     Wood statues  of sengon  experienced more rigorous cracks than those of mindi.   The  use of wood adhesives as coating materials gave a helter cracking protection than the wood filling agents. Although polyvinyl acetate could not greatly minimize the physical deformation  of belalu,  it revealed  to be the most effective coating material for cracking prevention.

Abstract

Wood samples  of  15 species  measuring  5 x  5 x  30 cm  were treated  with 5 percent  of BFCA preservative by hot and cold  soaking.  Hot  soaking  period  was respectiuely 1  hour,  3 houn  and 5 hours, with  temperature  range  of 65ᵒC ­-  70ᵒ C, followed by  cold  soaking  for  24 hours. The  test  result  of  experiment, after taking  both  retention and penetration requirements into  consideration  for wood uses  under  roof,  and  in the  open  air both  without   ground  contact,  showed  that  nine Wood  species  could  be satisfactorily  treated  under   the  experimental  conditions.   However, it is important  to  note  that  one  of  the  nine species,  i.e.  benuang   (Octomeles   sumatrana)  fulfilled  the  requirements   for  wood   usage  under   the roof  only  without ground   contact.  The preservation schedule proposed  for  nine wood species is also presented in this paper.
