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

This study   is intended   to recognize  the  behaviour  and  infestation   rate  of  marine  borers. Forty  samples  of pine  wood,  measuring  120  cm  x  5 cm x 5 cm,. vertically  floated  at Ram but Island seashore.  These samples  are divided   in  to  three  section:    top,  midle  and  bottom.    The observation   were carried out  after  1,  2,  3 and  6 months    by  splitting   the  sample.The results  showed  that  the  infestation   started  from  the bottom   upwards.  The length  and diameter  of the burrow  is controlled    to  a  certain  extent    by  the  intensity   of  the  borer population    in  the  wood.   When crowded,   the  borer  may grow  only  a few  cm.   After six  months   of  experiment,    the  infestation   rate of  samples  showed   the following   regression equation;  i.e,  top section  Y 1=   0, 134 (X)2,375,   milde section   Y2= 2,569  (X)1,113   and bottom  section  Y 3=  3,334  (X)0,142.

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.

Abstract

Dua puluh lima jenis kayu Dipterocarpaceae diuji sifat keawetannya terhadap serangan penggerek kayu di laut. Masing-masing jenis kayu dibuat contoh uji berukuran 2,5 cm x 5 cm x 30 cm, direnteng dengan tali plastik, kemudian dipasang di perairan pulau Rambut dan diamati setelah 6 bulan. Tujuan penelitian ini adalah untuk mendapatkan informasi tentang keawetan 25 jenis kayu Dipterocarpaceae terhadap penggerek kayu di laut. Hasil penelitian menunjukkan bahwa setelah 6 bulan, sebagian besar contoh uji mendapat serangan berat oleh famili Pholadidae dan Teredinidae. Lima dari 25 jenis kayu atau 20% tahan terhadap penggerek di laut. Giam durian (Cotylelobium flavum Pierre) dan balau laut (Shorea falcifera Dyer) termasuk dalam katagori sangat tahan, sedangkan giam tembaga (Cotylelobium melanoxylon Pierre), balau laut batu (Shorea elliptica Burck.), dan resak ayer (Vatica teysmanniana Burck.) termasuk dalam katagori tahan terhadap penggerek di laut. Kelima jenis kayu tersebut cocok untuk bangunan kelautan.
