Abstract

One  hundred   fifty   pieces  of  wood  consisting  of  15 species  were randomly   arranged in form  of  a raft and  floated at Rambut and Puntung  Java Islands seashore. The size of the wood  specimens  is 2,5 cm x 5 cm x 30 cm.                      The  samples  were  tested  against  two  principal  family of  marine  borers,   i.e.   teredinids  and pholads  and  evaluated after three  months. The  results  reveal that  most  of  the  tested  woods  were severely  attacked  by  teredinids,  except   Heritiera  littoralis, Heritiera javanica, Diospyros celebica, and  Eucalyptus platyphylla, but  these  species  were severely  attacked by pholads.  The infestation has two distinct  types,  characterited by its structure  and pattern  of  wood  boring

Abstract

The Mollusca  wood  borers,  normally  found  in Indonesian  sea waters, are divided  into  two  types,  i.e. Pholadidae  and Teredinidae.   Both  types  have different  characteristic  nature  of  infestation to  wood. This paper  deals with  a study on the borer  infestation   to  seven  tropical  commercial   wood  species.The  study   was  conducted at  Rambut Island  seashore  (on Java Sea)  using wood  samples  measuring  2.5 cm  by 5.0 cm by  80.0 cm.  The samples  were  randomly arranged at a raft  and  observed  after  8,  7 and  12 months.The  result  reveal  that  after 12  months most   of  the  samples  were  completely    attacked   by  the  Pholadidae  and Teredinidae.  However moderate  borer infestation was shown by  Eusideroxylon   zwageri, which  means that  this species  is relatively   resistant  to  marine  borers  infestation. Meanwhile,  the  infestation   rates  of  Pholadidae  and  Teredinidae   are significantly   different, and  they  have different characteristic

Abstract

Contoh respresentative dua ratus jenis kayu yang berasal dari beberapa daerah di Indonesia diteliti sifat keawetannya terhadap serangan penggerak di laut. Masing-masing jenis kayu dibuat contoh uji berukuran 30x5x2,5 cm, dirakit dengan tali plastik dan dipasang di perairan Pulau Rambut serta diamati setelah 6 bulan. Dari hasil penelitian tersebut dibuat lima klasifikasi keawetan berdasarkan intensitas serangan pada masing-masing contoh uji. Hasil penelitian menunjukkan bahwa hampir semua contoh uji mendapat serangan berat oleh Pholadidae dan Teredinidae. Lima jenis (2,5%) tahan terhadap penggerek di laut, dimasukkan ke dalam katagori kelas awet I, dan 10 jenis (5%) dimasukkan ke dalam kelas awet II. Sementara itu, sisanya 26 jenis (13%) termasuk kelas awet III, 50 jenis (25%) termasuk kelas IV, dan 109 jenis (54,5%) termasuk kelas V.

Abstract

Penelitian sifat fisis dan mekanis kayu jati (Tectona grandis L.f.) jenis lokal dan super dari daerah Binjai, Maros, Parung, Panajam, Kutai, Lampung, Bengkulu dan Palembang bertujuan untuk melihat perbedaan karakteristik sifat fisis dan mekanis kayunya. Hasil penelitian menunjukkan bahwa rata-rata berat jenis (BJ) kayu jati super lebih tinggi daripada kayu jati lokal, sedangkan BJ tertinggi pada kayu jati super adalah dari Binjai dan terendah dari Maros. Jenis jati lokal dan super berpengaruh nyata terhadap berat jenis basah kayu tersebut, sedangkan lokasi penanaman jati tidak memberikan pengaruh yang nyata terhadap berat jenis. Kayu yang terkuat adalah jati lokal dari Palembang, diikuti berturut-turut kayu jati super dari Lampung, jati lokal dari Kutai, jati super dari Bengkulu, jati super dari Kutai, jati lokal dari Binjai, jati super dari Parung, jati super dari Binjai, jati supr dari Palembang, jati lokal dari Lampung, jati lokal dari Sulawesi dan yang terendah jati super dari Sulawesi. Perbedaan BJ tersebut berpengaruh nyata pada kekakuan dan keteguhan tekan sejajar serat, sedangkan lokasi tanaman berpengaruh nyata terhadap kekakuan dan kekuatan patahnya. Kayu jati yang diteliti tergolong kelas kuat III-IV.

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

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.
