Abstract

Limbah pengolahan kayu jabon (Antochephalus cadamba Miq.) dan bambu andong (Gigantochloa pseudoarundinacea (Steudel) Widjaja) dimanfaatkan sebagai bahan baku pembuatan papan partikel. Penelitian ini bertujuan mempelajari pengaruh perbandingan berat partikel kayu jabon dan bambu andong terhadap sifat fisis dan mekanis papan partikel. Papan partikel skala laboratorium berukuran 35 cm x 35 cm x 1,2 cm dibuat dengan menggunakan perekat phenol formaldehida cair dengan enam macam komposisi campuran partikel kayu jabon dan bambu andong (100:0, 70:30, 60:40, 50:50, 40:60 dan 30:70). Hasil penelitian menunjukkan bahwa sifat papan partikel campuran kayu jabon dan bambu andong sangat dipengaruhi oleh komposisi material penyusunnya. Penggunaan partikel bambu andong dalam pembuatan papan partikel campuran kayu jabon dan bambu andong dapat menurunkan nilai pengembangan tebal papan partikel kayu jabon sebesar 11,19% sampai 40%. Penggunaan 40% partikel bambu andong dalam pembuatan papan partikel campuran kayu jabon dan bambu andong dapat meningkatkan nilai MOR sebesar 11,49%. Papan partikel campuran kayu jabon dan bambu andong dalam penelitian ini memenuhi Standar Nasional Indonesia dan Standar Jepang untuk papan partikel kecuali untuk nilai MOE.

Abstract

It has been known that lignin can be used as plywood adhesive for exterior purpose. The sources of lignin are black liquor indulin-AT (commercial lignin).A study on lignin formaldehyde  resin making from  black liquor and indulin-AT was done and the results were  used to predict  the effect of lignin  isolate type and L/F  mole ratio on plywood bonding strength. The results show taht the type of lignin isolate and L/F  mole ratio have highly significant  effect on plywood bonding strength. The mole ratio L/F of 1 : 1.50 and 1:1.75 by lignin isolate from  indulin-AT result in plywood bonding strength about 7.5 kg/cm2 and 8.8 kg/cm2,   respectively. The bonding strength of these plywood conforms with the 1983 Japanese standard for exterior purpose.

Abstract

Bungkil biji jarak pagar merupakan limbah dari produksi biodiesel. Beberapa penelitian menyebutkan bahwa bungkil masih mengandung kadar protein yang tinggi sehingga dapat digunakan sebagai alternatif suplemen pakan ternak. Namun dikatakan juga bahwa bungkil biji jarak mengandung racun yang berbahaya seperti saponin, lektin (kursin), inhibitor tripsin clan ester forbol. Penelitian ini dilakukan untuk mengetahui kandungan gizi, mendetoksifikasi racun dalam bungkil dan menguji toksisitas akut bungkil terhadap tikus putih. Analisis fitokimia menunjukkan bahwa detoksifikasi dapat mengurangi senyawaan saponin dan alkaloid contoh. Berdasarkan analisis proksimat, beberapa parameter seperti kadar abu, lemak dan gula pereduksi contoh dipengaruhi oleh detoksifikasi, sedangkan kadar air, protein dan serat kasar tidak dipengaruhi oleh detoksifikasi. Berdasarkan standar proksimat pakan ternak, ampas bungkil biji jarak cocok untuk pakan ruminansia. Uji toksisitas akut menunjukkan bahwa tidak ada kematian dari hewan coba, sehingga diduga LDSO di atas dosis 15 g/kg BB dan ampas bungkil biji jarak dapat digolongkan non toksik.

Abstract

The investigation was aimed at assessing the influence of tree level of maturity and the amount of additive used in the sulphate cooking process on the properties of the corresponding resulting pulp. The trees selected in this regard were Gmelina arborea Roxb., consisting of four levels of maturities, i.e. 6, 8, 10 and 12 years. The additives used in the process were polysulfide (PS) and anthraqinone. The anthraquinone (AQ) was added 0.1 percent, without PS, and in the other cooking PS at 4.0 percent, without AQ. Meanwhile, this modified sulphate process was also conducted with any additive 4.0 percent PS and 0. 1 percent AQ. As a control. the sulphate cooking without both was carried out as well. Other cooking conditions were kept constant, i.e. active alkali 16 percent, sulphidity 25 percent, wood to liquor ratio 1 : 4, maximum temperature 170 °C. and total cooking durations 4 hours.The results revealed that the increase in tree maturity up to 10 years produced pulp with the highest yield. However. the pulp yield decreased when the maturity reached 12 years, which was the case when the pulp was obtained from the 6-years wood material. The use of 0.1 percent AQ additive did not improve the pulp yield but decreased the kappa number. The highest yield was obtained at 4. 0 percent PS additive, followed by the one using the combination of 4. 0 percent PS and 0.1 percent AQ.Melina wood from the corresponding 6 year old trees appeared technically suitable as raw material for pulp, since it strength was fairly high to meet the Indonesian National Standard (SNI) for the one from long-fibered softwood. Besides that. the use of additive improved the strength of pulp.

Abstract

Disturbed soil and vegetation caused by logging operation is difficult to be avoided, even in good logging operation.Past studies related to this problem.  shows that forest  concessions in Sumatera and Kalimantan used Indonesia Selective Cutting System (TPTI) as a basic activity in logging operation. However, because of the weakness of goverment control activity, most of the companies were looking for  financial benefit only and neglect the sustainability of the forest.The aim of this study is to assess the number of commercial trees (diameter 20 m and up) damaged during logging operation.The study was carried out in two forest  concessions:  PT. Batasan/A and PT. Tanjungpura Bhakti/B in West Kalimantan,The results shows that :1.   The average percentage  of commercial trees damaged of diameter 20.  cm and up during  logging operation   are 4. 6  %  in A concession and 5. 6 % in B concession.2.   The average number of trees in concession A are 8. 9 trees/ha while in concession B is 7. 8 trees/ha.

Abstract

The  development  of  domestic   market  of  plywood  relies  heavily  on  the effective   demand  for plywood  or buying  power   in  real sense.                                                                                                               This  research is aimed  at studying   the pattern   of  relation  ship  between   the  consumption  of plywod  by household in Central  Java  and  East  Java  and  some  factors  influencing  it.The  average volume  of plywood  annually  consumed   by household   is of 0.0152  m3 per year per  family   (with  average of  3. 6 persons/family).   The  variables  that  influence  the effective  demand  of plywood are family  income,  price  of plywood and  the  number   of  family   member.    The  elasticity   of  the  demand   of  the  three  factors  is  of  0.3365  implying   that  the consumption of plywood  is inelastic  to the change of  the three factors.

Abstract

Tree felling  operations in  Indonesia are commonly  done by  standing or bending  workers,  using chain saws.  These techniques cause  high  stump residues  (about  8.94%)  and  increase  workers' energy  consumption by 12% for standing and 55% for bending  workers' positions.From ergonomics point of  view, above techniques cause  body position to be less natural,  produce longer static muscular work,  reduce  work hours, create early fatique  and physiological effect  like work stress.This  paper described  the  effect of  improved felling method on work  stress of  chain saw  operators  and  construction wood production.  An investigation was carried out in two private forest companies in Central Kalimantan  in 1988. The results are as the following:The  improved  felling  method decreases  work  stress  of  chain  saw  operators;  showed   by the reduction  of pulse  rate to the amount  of 13-15 beats/minute.                                                                          The  improved  method  of felling  trees with  buttress  heights  of  < 50 cm and 50-150    cm cause the increase in construction  wood products  about  0.354  m3 and 0.542 m3  per  tree felled,  respectively.

Abstract

Penelitian ini bertujuan mengetahui pengaruh umur, posisi batang dan tingkat kekeringan terhadap sifat fisik dan kualitas pengeringan bambu andong. Sifat fisik yang diuji dalam penelitian adalah kadar air segar, kerapatan dan penyusutan pada arah tebal dan lebar bilah batang pada 3 tingkat kekeringan bambu.. Metoda pengeringan yang digunakan adalah metode pengeringan alami dan metode pengeringan oven. Hasil penelitian menunjukkan bahwa bambu andong utuh umur 3 tahun yang dikeringkan kualitasnya kurang baik dibandingkan dengan bambu yang berumur 5 tahun. Penyusutan dimensi pada bambu berumur 3 tahun, baik pada arah tebal maupun lebar bilah batang sangat tinggi, sehingga batang bambu yang dikeringkan menjadi keriput/kolap. Ini disebabkan pada bambu berumur 3 tahun, kadar air segar lebih tinggi, porsi berkas pembuluh lebih rendah dan porsi parenkim lebih tinggi dibandingkan bambu umur 5 tahun.
