Abstract

The result of a study on the properties of particle board made from logging waste is reported in this paper. The wood species used in the study as raw material for particle board are meranti (Shorea sp.), ramin (Gonystylus bancanus Kurz.) and combination  of the two species. The result shows that wood species and particle size has a significant effect on the water absorption and thicknessswelling of particle board. Bending strength  (MOR) of particle board is only affected  by wood species, while Modulus  of elasticity, internal bond and shear strength are not affected by wood species and particle size. In general the physical and mechanical properties  of particle  board studied  meet the FAO standard for low density particle board.

Abstract

The paper presents test results of 50 wooden poles from logged-over forest of Lampung, Owing to difficulty in obtaining pole materials for the test, the number of pole samples tested were below the ASTM D-1036 requirement. The data, however, is expected to be useful for comparing field test result with those obtained from small specimen in the laboratory, which has been used as a basis for evaluating timber suitability for pole material. The results show that the location of failure in 41 out of 50 pole tested as simple cantilever occur near pole tip, where the pole diameter were between 1.11 to 1.40 times pole diameter where the load is applied. In the remaining 9 poles, the maximum fiber stress occur around the ground line. The results also show that wood density had no significant effect on pole strength. This is in contrast with that commonly obtained in a laboratory test, in which strength is generally related to wood density. Using pole circumference data obtained in the field, an attempt was made to establish equation which describes pole height - circumference relationship for some selected species. Two forms of equations were tried, namely: Y = AXB and Y = A + BX. The exponential form turned out to be of a better fit. The data on pole taper presented in this paper can hopefully throw some light for future compilation of a table on pole dimension and specification for Indonesian wooden pole species and in a derivation of fiber stresses from strength values of wooden poles.

Abstract

Manufacturing trials of medium density fiberboard from logging wood wate have been conducted on a laboratory scale at the Forest Products Research and Dewlopment Centre, Bogor. Wood sample used in this study were obtained from South Sumatera logs of having a fairly wide range of specific gravity from 0.37 - 0.61. Pulp preparation were carried out by using the conventional cold caustic soda process at concentration of 36 gram per liter; wood to liquor ratio of 1 to 7 and soaking time of 24 hours. In this experiment the role of the pH of the slurry was investigated at seven levels being from pH 3 to pH 8 with one pH interval. Medium density fiberboard are formed by applying cold pressure of 10 kg/cm2 for 5 minute, and hot pressure of 25 kg/cm2 for 3 minute at 180°C. The pulp yield and alkali consumption were tested, according to the Libby experiment pulping by cold caustic soda process. Average pulp yielda were between 89,6 - 91,2 per cent with relatively high lignin content ranges from 17,2 - 24,8 per cent. The alkali comsumptions in the spent liquor throughout the experiment were between 10, 7 and 13, 7 per cent. This experiment reveals that except for density, other properties were significantly in fluenced by the level of pH. Medium density fiberboard produced from slurry of having the pH of 3, 4, 5, 6 and 7 appear to have the density, water absorption, tensile strength modulus of rapture and modulus of elostisity comparable to that of the FAO Standard. In general, the pH 5 produce medium density fiberboard of better physical properties.

Abstract

A  study   of  quality  control application on  sawn-timber  was   conducted  on  several sawmills in  Sumatra, West Kalimantan and East Kalimantan. Sample sawmills are selected based   on  market orientation and the availability of drying facibilities.The objectives of this study are to introduce new methode of quality control for sawn timber, in this target sise determination, and to evaluate the quality control practices in exitng sawmill operationt.The results of the study show that all the sampled sawmills did not have a apecific program of quality control, nor special personnels responsible for quality control.Green board thicness set by surveyed sawmills were higher than what is actually reguired, ranging  between  1  to 23 percent above the calculated target size. This is an indication that there is  a  lot of room improving the efficiency of raw material usqge through the application of target size settling  formula.

Abstract

The green ultimate stress values of 13 Indonesia timbers from East Kalimantan are presented in this paper using the _ASTM D 145 - 70 test method. The result indicates a high coefficient of variation (53%) for work to proportional limit (Gonystylus bancanus), while the lowest recorded is 5,5% for compression perpendicular to the grain (Shorea ovalis). An estimate _of the dry ultimate stress (table 2), green basic stress (table 3) and dry basic stress (table 4) are attempted using regression equations.
