Abstract

Tujuan penelitian ini adalah penerapan pengawetan bambu baru ditebang dengan bahan pengawet senyawa boron. Delapan belas batang bambu dengan panjang dan diameter yang bervariasi dipungut dari Ciapus di Bogor. Batang bambu yang baru ditebang dimasukkan ke dalam larutun bahan pengawet senyawa boron secara terpisah masing-masing selama satu, tiga dan lima hari.Hasil penelitian menunjukkan bahwa retensi bahan pengawet dapat ditingkatkan dengan cara meningkatkan waktu pengawetan dan konsentrasi larutan yang digunakan. Hubungan antara waktu pengawetan dan konsentrasi yang digunakan menunjukkan perbedaan yang nyata. Retensi maksimum sebesar 7,64 kg/m3 dicapai dalam waktu lima hari dengan konsentrasi larutan 10%.

Abstract

Jati (Teaona grandis L.f.) cepat tumbuh yang dikembangkan melalui kultur jaringan yang bertujuan untuk meningkatkan pasokan kayu dari hutan tanaman. Informasi mengenai kualitas kayu jati cepat tumbuh belum banyak diketahui. Salah satu parameter kualitas kayu jati dapat dilihat dari kelas awetnya. Penelitian ini bertujuan membandingkan kelas awet antara jati cepat tumbuh dengan jati konvensional pada berbagai umur pohon. Contoh uji ukuran 5,0 cm x 2,5 cm x 2.0 cm diuji terhadap rayap kayu kering (Cryptotermes cynocephalus Light.), contoh uji ukuran 2.0 cm x 0.5 cm x 0.5 cm diuji terhadap rayap tanah (Coptotermes curvignathus Holmgreen.) dan contoh uji 7,5 cm x 5 cm x 1,5 cm diuji terhadap bubuk kayu kering (Heterobostrychus aequalis Waterh.) Hasil penelitian menunjukkan bahwa jati cepat tumbuh umur 5 dan 7 tahun serta jati konvensional umur 5, 7 dan 15 tahun mempunyai kelas awet rendah (kelas V-III) terhadap rayap kayu kering dan rayap tanah dan mendapat serangan ringan terhadap bubuk kayu kering. Namun demikian jati konvensional umur 35 tahun memiliki kelas awet tinggi (kelas I) terhadap rayap kayu kering dan rayap tanah dan mempunyai ketahanan yang tinggi terhadap serangan bubuk kayu kering.

Abstract

The experiment was carried out to study the role of lignin as dry wood termite Cryptotermes cynocephalus Light food. The C. cynocephalus termite was given lignin and cellulose food, separately or both in the test petridish.These research conclude that :1. C. cynocephalus termite besides eating cellulose as main food also eating lignin.2. The survival of C. cynocphalus termite was not influenced by the kind of food i.e. cellulose or lignin.3. The feeding activity of C. cynocephalus termite was highly influenced by the kind of food. The highly feeding activity of C. cynoceph alus was cellulose.4. C. cynocephalus termite prefers the cellulose than lignin,

Abstract

Many factors determine the susceptibility of wood to marine borer attack. It is thought that one of them is the specific gravity.A study on the relationship between wood specific gravity and the intensity of marine borer attack was conducted in the seashore of Rambut Island (in Java Sea) in 1988. Samples were made of woods of industrial plantation forest species with the size of 30 cm long, 5 cm wide and 2,5 cm high. The samples were randomly arranged like a raft and put inside the sea. They were observed after three months.The results reveal that specific gravity asertain the intensity of marine borer infestation, except Tectona grandis, Tectona grandis 12 the most resistant to marine borer attack although its specific gravity is lower than Eucalyptus urophylla, Altingia excelsa, Acacia mangium and Pometia pinnata.

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

Sixty  two  Indonesian  wood species  were exposed  to  marine  borers for  determining  their resistances. The study was conducted at Rambut Island seashore using wood samples measuring 2,5 cm by 5 cm by 30 cm.  The samples were randomly arranged using nylon rope immersed in the shore and then observed after six  months.   Results revealed that most of the samples  were completely attacked by Martesia striata Linne of the Pholadidae family, Teredo bartchi Clapp.,  Dicyathifer manni Wright and Bankia cieba Clench.,  of the Teredinidaefamily.  Nine out of 62 wood species i.e.   14.5% were resistant to marine borers. Eusideroxylon zwageri T.  et B.,  was classified as very resistant (no attack), while Diospyros celebica Bakh.,  Mimusops elingi  L.,  Parinari corymbosa Miq.,  Tectona grandis lf,  Trestania maengayi Duthii.,Trestania  whiteana Griff,  Vitex cofassus Reinw.,  and Vitex pubescens Vahl. were categorized as resistant (light attack). These nine wood species are suitable for marine constructions.

Abstract

Marine  borers are wood destroying  organisms  living in the sea, brackish  and estuarine  water. Environmental   conditions  such as salinity, pollution  and temperature  of  the sea water influence  the activities  and precence  of  marine  borers.One hundred pieces of wood from  five  species had been exposed  to marine borers in four  different  salinities for  nine months. The test sites chosen were around  Gulf  of Jakarta  i.e.  about 3 km off  shore, and at three  locations  along  a canal of  brackish fishpond,  respectively  in the estuary,  1  km  and 2 km from the shore.The result shows that at the sea site where the salinity  is relatively stable around 29 ‰ – 30‰ ,  all of the wood tested are badly attacked  by Mollusc  belonging  to the species of Martesia  striata  Linne.,  Dicyathifer  manni  Wright.,  and  Bankia  campanellata  Moll/Roch.    Along  the canal where the salinity is between 5‰-30‰, damage is only small.  The result also shows no sign of attack on all samples exposed  along the canals, although  the salinity is not significantly  different  from that of  the estuary.
