Abstract

Aren timbers are suspectible to wood detercrating agents especially when used in contact with ground and/or exposed to the weather. Therefore, proper treatment is neccessary to protect them from insects and decaying organisms. The success of aren timber treatment depends on wood structure, treatment processes, and other factors.Treatment schedules of different processes were established through a series of experiment. For example, longer pressure period and higher preservative concentration are more suitable for products used in contact with ground than those used outdoor or without contact with the ground. In Anonymous (1987), the target CCA retention ranges from 3.3 to 10.6 kg/m3, and CCB from 6.4 to 11.4 kg/m3, and BFCA from 6.0 to 8.6 kg/m3, depend on preservatives and end products.The experimental results indicate that the retention of preservatives exceeds the minimum values of specification. Recomended treatment schedules for each process are presented.

Abstract

Two units of sawmill in Lampung (Sumatera) and three units in West-Java have been visited for the purpose of this study. Determination of target size on each sawmill was firstly done by collecting data from thickness measurements of 100 board samples. The data was then calculated using the most common formulas used for determining the lumber target size.The result of the study revealed that actual size produced by two sawmills surveyed were higher than target size, ranging from 1.08 to 1.58 mm. The actual size from three other sawmills were lower than target size, ranging from 0.26 to 2.18 mm. The sawmill A has apparently the best sawing capability. This was indicated by the smallest thickness range either within or between board i.e. 0.89 mm and 0. 79 mm. Meanwhile, its total sawing variation was smallest i.e. 0.49 mm.The result of this study was an indication that there is a need for improving the efficiency of sawing process through the application of target size determination.

Abstract

Wood preservative penetration and retention on five wood species using hot and cold bath process was studied. Wood samples measuring 5 cm x 5 cm x 60 cm were immersed in BFCA preservative solution under temperature of 70° C for nil (control), one, two and three hours then cooled for a day.The result indicates that red meranti (Shorea platycados V.Sl .) is more permeable compared with other species (bangkirai, bungur, damar laut and kapur). In red meranti, one hour immersion in hot preservative yields penetration which conforms with the SKI C-bo-008 Standard for wood building, whereas in other 4 species, the treatment does not seem to be more superior. compared with cold immersion method.

Abstract

Females of ambrosia beetle Xyleborus sp., one of the most destructive wood boring insects on lone logs (Pinus merkusii), were reared on rubberwood sawdust base media. The media were frepared in test tubes and one famale pertube was then introduced. These cultures were maintained in a dark room at 28°C and 70 % RH for 40 days. Observations were made for number of branches and length of galleries system through the tube walls, and number of progenies produced by the beetles after the media were dissected.It was shown that of the 22 culture tubes, 18 tubes were developed. Most of the beetles extensively tunneled to and fro criss-cross within the media. Mean branch number and gallery length were 16. 7 junction and 46.4 cm tracks ranging 0 - 33 and 0 - 52 respectively. The average of progeny number was 47.9 per tube with one male for about 14. 7 females. It seemed that both number of branches and length of galleries system indicatively correspond to the level of the beetle fecundity.

Abstract

An investigation on hauling productivities and hauling costs of three types of log hauling trucks was carried out at three logging companies in West Kalimantan in 1988. Three types of logging trucks, i.e. Nissan with semi trailer, Berliet with semi trailer and Nissan truck, were observed. The productivities of trucks were gathered through time study while the hauling costs were calculated based on secondary data. The purpose of the investigation is to find hauling productivities, operating costs of trucks and hauling costs.The results of the investigation are as follows :The average hauling productivities of Nissan with semi trailer, Berliet with semi trailer and Nissan trucks are 484,99m3 km/hour, 492,02 m3 km/hour and 292,07 m3 km/hour, respectively .The average hauling costs of Nissan with semi trailer, Berliet with semi trailer and Nissan Trucks are Rp. 63,08/m3 km, Rp. 64,66/m3 km and Rp. 84,39/m3 km, respectively.The differences in both the hauling productivities and hauling costs either between Nissan logging truck with semi trailer and Nissan loging truck or between Berliet logging truck with semi-trailer and Nissan logging truck were highlysignificant because of the differences in logging truck capacities, transport distances and driver skills. But the hauling productivities and hauling costs between Berliet logging truck with semi-trailer and Nissan logging truck with semi trailer did not differ significantly because the logging truck capacities, transport distance and driver skill in PT. Kawedar are comparatiuely simmilar to those in PT. Erna Juliawati.Hauling costs by using smallar trucks are more expensive than those by using larger trucks

Abstract

The media used in the experiment were sawdust of eight wood species mixed with 1% calcium carbonate (CaC03), 1% gypsum, 0.5% fertilizers i.e. urea, ammonium sulphate (ZA), KCL, NPK and trisuperphosphate (TSP) and distilled water, respectively. The substrate was cooled after autoclave sterilization before being inoculated with pure culture of oyster mushroom. The mature mushrooms were harvested daily after the growth of fruiting body.The media started producing mushroom two months after inoculation (28 - 45 days). The highest yield was obtained from rubberwood sawdust mixed with ZA (362.43 g) and the lowest yield was on teak sawdust containing urea (90.14 g) per 500 grams media. Media from rubberwood, weru, jeungjing and pulai sawdust were suitable for mushroom culture. Fertilizer supplement seems to improve mushroom yield. ZA, urea were more effective than KCL fertilizer for mushroom production.The average Biological Efficiency (BE) of entire treatments was 84.32% (35.25-140.23%). The relatively high BE was obtained from weru, rubber and jeungjing and the lowest BE was on teak sawdust media.
