Abstract

One hundred  fifty  pieces   of  wood  from  five species  were exposed   to marine  borers in three   different locations  for periods   up  to  three  months   at  different   periods.   The  tests  were  conducted   around  Jak9rta  Gulf  i.e  about   3  km  off shore from Mauk  from  January  -   June  1986, Rambut Island from  July - November 1986, and Puntung, Java lsland from  November 1986   -   February 1987. The  result shows  that  most  of  the  wood  tested  were  badly  attacked   by Molluscs  belonging  to the specise Martesia striata  Linne.,   Teredo  bartschi  Clap.,   Dichyathifer  manni  Wright.,  and Bankia campanellata Molli Roch.  Diospyros  celebica Bahh, wood  seems  to  be resistant  to  marine  borers.   The  intensity   of  borer attack  on the woods  in the three locations  are not significantly different.

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.

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.

Abstract

The community of subterranean  termite in any site is influenced  by the soil condition.  In three places studied  six species of  termites  were found  namely  Macrotermes  gilvus   (Hagen),   Microtermes insperatus Kemner, M. incertoides Holmgren,  Odontotermes  grandiceps   Holmgren, Capritermes  buitenzorgi  Holmgren  and Coptotermes  havilandi  Holmgren.In the yard of National  Oceanological Institute  Jakarta  C. havilandi  was responsible for  the damage of the building.  In the yard  of Forest Product  Research and Development   Centre in Bogar four  species of termite  were observed,  while at Cibodas Botanical  Garden only  one species was found   namely  C. buitenzorgi.  The latter termite  did not seem to cause to the building.

Abstract

The  result  of  a  study  on  the  effect  of soil moisture  content and  temperature  on subterranean  termite  distribution is presented   in this paper.The study  shows   that   soil  moisture   content   and   temperature  has significant   effect   on  subterranean  termite distribution. Four  subterronean   termites   namely  Microtermes  incertoides,  M.  insperatus,  Macrotermes  gilvus and Coptotermes  curvignathus  were  identified   at  the  first  location   (soil  moisture  content  = 21. 71 %,  soil  temperature   = 25. 7oc).   Whereas  at  the  second   location   (soil  moisture content =  8.36%,   soil  temperature  =  27.5°C)   two  species  only were  identified   namely  M. incertoides and  M.  insperatus.
