Abstract

This paper is  dealing with  the  influence  of drying  methods  to feeding  activity  and survival of Cryptotermes  cynoce- phalus   dry­wood  termite.  The  result  shows   that   drying   methods  have  an  effect on  feeding activity  and  survival of C.  cynocephalus.   Besides  the  drying   methods,  wood  species  has also  an  effect   on  such  both  factor. The  oven method is  more  advantageorus than  desicator  method   which  is  more  selective  and more practice.

Abstract

 Oyster  mushroom   (Pleurotus  ostreatus)  was cultivated   on  logs of  five  wood  species,  i.e.  hamerang  (Ficus  grossularoides  Burn.f.),   jeungjing  (Albizia  falcataria (L.)  Eosb.),   jirak  (Symplocos  fasciculata  Zoll.),  kihuut   (Vernonia arborea Ham.)   and  manii (Maesopsis eminii  Engl.).The logs were kept  in a house, at Gunung Bunder Forest  Complex, Bogor (first experiment)    and  under  soka  trees  in Bogor (second  experiment).The  logs start producing   fungus  two  months  after  inoculation. After  eight month  observation, the highest yield per log was obtained  from  manii 1139.90   g (in a house) and  1171.62 g (under soka trees; and the lowest yield was on jirak (0.99 g).                                                                               Total  yield  during  the experiment   per  m  of  log,  under  soka  trees was higher than that  cultivated  in a house Manii and  hamerang  logs probably belong  to  media  for  oyster   mushroom   than  other  species

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

Two regrowth wood species, i.e. tusam (Pinus merkusii Jungh. et de Vr.) and mangium (Acacia mangium Wild.) were used in this study. Specimens measuring 25 mm x 25 mm x 50 mm and 5 mm x 25 mm x 25 mm were prepared for testing against dry-wood termite (Cryptotermes) and subteranean termite (Coptotermes) respectively. All specimens were air-dried  to approxi mately 16-18%  moisture content. One group of the specimens was further  oven - dried to reach moisture  content of  6-8%.  Furfurylation  was carried out by soaking  wood specimens for 24 hours  in a 98% fuifuryl  alcohol  solution  containing  0.35%  (v/v) of  ZnCl2  as catalyst. Furfurylated specimens were then cured at  l000C  for 48 hours.  Control and treated specimens were exposed to dry-wood and subteranean termites for 12 and 4 weeks respectively.Treated specimens revealed a weight gains of  10 to 40 % depending on size of specimens and  wood species. Speciesmens usd for testing drywood termites gained less weight than those of  subteranean termites. Tusam  specimens  markedly  showed  a  higher  weight  gain  than mangium.  Furfurylation using method 1 resulted in comparable weight gain to that of method 2. Control specimens of tusam an mangium are both encountered susceptible to dry-wood and subteranean  termite  attacts.  Tusam  had  less initial durability  against  Coptotermes  than mangium, but the wood species had a similar durability against Cryptotermess.  The modified wood with furfuryl alcohol abviously possessed an improved durability  upon the two termites. Tusam specimens gained more durability improvement than mangium.

Abstract

The resistance of 109 Indonesian wood against subterranean termite (Coptotermes curvignathus Holmgren) attack has been assesed. The wood species come from several regions in lndonesia. The woods were each cut to small samples measuring to 2.5-cm by 2.5-cm by 0.5-cm and subsequently exposed to 200 subterranean termite workers for four weeks.The results revealed that 68 out the 109 wood species (i.e.62.3 percent) were classified as themost durable (classes I and II): and the rest, i.e 41 species (37.8 percent), were classified as lower durability (i.e. classes Ill, IV, and V) and therefore in their application need a preservative treatment.

Abstract

Beside temperature  and humidity,  soil type is an important factor  that effects  termite population  size.  From  three types of soil selected for the study  (association  of dark grey alluvial and greyish  brown,  grey regosol and association  of  low peat  glei and grey alluvial),  three  termite species, namely Microtermes insperatus Kemner, M. incertoides Holmgren and Macrotermes  gilvus (Hagen) were observed.  These three species of termite inhabited  the low peat  glei and grey alluvial soil.  In  the association  of  dark  grey alluvial  and greyish  brown  soil, only  M.  gilvus  was observed.  This same species of  termite  was also spotted  the grey regosol soil.The number of termite individuals found in the three  types  of soil  were obviously  different. The greatest  number  were observed  in the association  of low peat  glei and grey alluvial soil.

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

This paper deals with reseach results on bamboo preservation using boucherie method. Two bamboo species,  namely andong (Gigantocloa verticillta Munro) and tali  (Gigantochloa apus Kurtz) were treated freshly using Borax (Na2B4O7. IOH2O)  solution with strenght solution of 5% as preservative. One of butt of the 8 length bamboo was immersed 10 cm in borax solution for 2. 4. 6, 8.  and  10  days and  the penetration of preservative were observed. The results showed  that  the  penetration  of  preservative  in  andong  bamboo for 2. 5, 6,  8,  and 10 consecutively  were 131,40 cm, 304,92 cm, 308.42 cm, 469,88  and 315,28 cm, while  in tali, bamboo  were 68,30 cm,  116.83   cm, 141,88 cm  and 128,17 cm,  respectively.  Maximum pnetration of preservative was achived in 8 days immersion for andong and 6 days tali.
