Termites (Isoptera) as one of local feed in several places in Indonesia just like Irian jaya, is available, easy to find and having protein in a high level. Termites nest which high about 0,5-2 metres above ground is easy to find at all low area merauke which having land areal about 20.000 ha, otherwise in other distrik, it can easily to find in a forest especialy in a new open land for Agriculture and transmigration. The purpose of this experiment was to study the effects of Glyptotermes montanus Kemner termites suplementation as protein resource in the diet of broiler strain Rokky-301. One hundred eighty DOC Rokky-301 were randomly divided in to five treatment with three replicates of 12 chickens each. The treatment diets were basal diet (R0), basal diet + fresh termites 0,5% (R1), basal diet + fresh termites 1% (R2), basal diet + fresh termites 1,5% (R3), and Comercial diet (R4) as positive control. The chickens were fed the treatment diets over 50 days. The results showed that the chicken fed R3 diet had significantly higher body weight gain than did chicken fed other diets except for chicken fed commercial diet (R4). Feed consumption of chicken fed R0 diet was significantly higher than other treatment diets. However 1,5% fresh termites suplementation (R3) significantly reduced feed consumption. Basal diet (R0) had highest feed conversion compared to other treatment diets. However 1,5% fresh termites suplementation (R3) was significantly improved feed conversion compared to other treatment.

Pine woolly adelgid is a recently found exotic pest attacking seedling up to grown plants of Pinus merkusii plantations forest. Since its discovery, there were not much information about it. The objectives of this research were to study pine woolly adelgids distribution, symptoms and indicators, and its scale of infestations on Pinus merkusii plantation in Java, to determine the presence of any specific P. merkusii sites invaded by pine woolly adelgids, considering the pests were native to boreal and temperate areas. Hypothesis was pine woolly adelgids infestation on P. merkusii in Java is consistent with their native distribution. There were 9 Forest Management Unit (KPH) with infested P. merkusii plantations which were located at altitude between 900 to 1,700 m asl. with temperature ranging 16-22 °C and air humidity 80-90%. This indicated that Pine Woolly Adelgids required low temperature to survive, which was consistent with their original distribution. Host preference with regard to scale of infestation was closely related to temperature, altitude, and number of trees per hectare. The scale of infestation varied among regions, from light to heavy infested/death of trees.

The research done based on the fact that the log from natural forest could not fullfil the need of domestic forest industry. Annual available cut from natural forest in the year 2007 was only 9.1 million m3 while forest industry domestic country in the year 2005 reached 44.5 million m3. Raw material crisis was the most problem facing by domestic forest industry and the solution could be come soon as posible. The establishment of social plantation forest is one of the government program to solved the lack of forest industry raw materials. The species for social plantation forest are available more than enough. Previous research done in the year 2009 shown taht most of HTR log was small diameter, short sortimen, heart wood presentation of juvenile wood was very high. The result of research shown that the basic characteristics of three species of HTR namely: Jabon, sengon and pulai have a good colour (bright), moderate texture, fibre is slim to interlocked, have no decoratif form, bulk density low. The characteristic of 6 species HTR was: variation in colour, good texture until moderate, fibre direct until interlocked, the wood have beautiful decoration, moderate bulk density. Basic of characteristic of wood is very important in affacting the quality of the products. An effort to increase the quality of HTR wood should be done so that the use of HTR product becaming important to suggest the developing of creative industry.

Bamboo is known as fast-growing species that could be derived into various products. However, bamboo is suspectible to the wood destroying organisms. Preservation is one way to improve the service life of bamboo. This study aimed to analyze the effect of differences in anatomical structures of betung bamboo (Dendrocalamus asper Backer) and andong bamboo (Gigantochloa pseudoarundinaceae (Steudel) Widjaja), and the effect of pressure on the flow time and retention of entiblu preservative in the Boucherie method. Bamboo stems with diameters of 10-14 cm were cut in 1; 1,5; 2; and 2,5 m lengths. The bamboo stems with moisture content of around 30% were preserved by 5% of entiblu preservative solution. The data observed were the flow time of the preservative entiblu solution from base of the stem until dripping on the top of the bamboo culm, and the retention of preservative. The anatomical structure of the bamboo trunk before preserving was also observed. The results showed that the average flow times in andong bamboo and betung bamboo were 37.75 minutes and 41.50 minutes, respectively. The average retention of entiblu solution on andong bamboo was 3.49 kg/m³ and on betung bamboo was 3.60 kg/m³. Keywords: andong bamboo, betung bamboo, anatomical structure, boucherie method, entiblu preservative

The survey was conducted to 200 houses in the four places. The result showed that wood biodeterioration occured in most (90%) house buildings. Doors, windows and roof structures were the most frequent attacked by biodeterioration agents. Decay fungi attacked wet wooden house components, mainly lisplank and ceiling, whereas termites attacked mainly doors, windows, poles and walls. The volume of damaged wooden house components in Lembang and Bogor were higher than those in the warmer and drier regions, Serang and North Jakarta. The average economic loss due to wood biodeterioration in a houses was about Rp28 000/year. However the economic loss per region was quite high, about two billion rupiahs per year in Serang and more than eight billion rupiahs in Bogor City.

Subterranean termite, Macrotermes, play important role on plant nutritive cycles through disintegration and decomposition of organic matter processes. In the other hand, subterranean termite can cause wooden damage in the nature and human dormitory as well. Therefore, Macrotermes are potential pest and need to be controlled. Effective pest-control of subterranean termite can be made when their species status and distribution are well known. This research is aimed to identify the status of species and the dispersal of Macrotermes at their natural habitat in order to explore natural bio-resources richness and as an effort towards effective pest-control due to increasing risk of attack. Survey method was used termite samples were collected at four different locations which are defined by global positioning system (GPS). Nest classification is according to Meyer et al. (2003). The nest mapping is based on the elevations of their natural habitat in Gunung Halimun Salak National Park (900-1000 asl), and (600-700 asl), Yanlappa sanctuary (200-300 asl), and Ujung Kulon Nasional Park (0-100 asl). Phylogenetic relationships analysis showed that subterranean termite Macrotermes in the natural forest community are belongs to one big group Macrotermes gilvus Hagen. Based on nest size, the colony of Macrotermes can be classified into three different sizes: large, medium, and small nest. Large and medium nest can be found in large amount in Yanlappa sanctuary (15 and 23 colonies, respectively) and the majority of small nest occurred in Gunung Halimun Salak National Park at 900 asl (78 colonies). Temperature and humidity is the most environmental factor that can influence on termite and other factor is rain fall, soil structure, and plant vegetation.

Enhancement of surface appearance of wood products in wood working industry has been done by application of wood stain. However, the use of wood stains has been recently limited due to emission of a hazardous material. Through this work a new technique of ammonia fuming has been experimented. The purpose of the research work was to investigate the effect of ammonia fuming and wood characteristics on the surface appearance of nangka wood (Artocarpus heteropyllus). The experimental result showed that ammonia in the volume of 2 liter could change significantly the natural color of (16 x 8 x 2) cm size nangka wood after 24 hours of fuming. Increasing in the period of fuming to 48 hours did not provide any difference in color compared to the 24 hours of fuming, however the 48 hours fuming generated deeper changes in color on the surfaces of the wood. Heartwood of nangka was observed to generate more significant changes in color compared to the sapwood. Fresh wood produced a darker color than air-dried wood. The wood treated by ammonia fuming showed an increase in resistance against termite and decayed fungi attacks. Keywords : ammonia fuming, finishing, heartwood and sapwood, preservation
