Abstract

experimental laminated veneer ( 5 - ply ) were made from 12 wood species veneers glued with urea formaldehyde. Thickness of veneer was 1.5 mm and the range of veneer density was 0.38 - 0.83 g/cm3. Veneers were divided into 3 groups based on their densily i.e. low, medium and high. The laminated veneer properties were tested in accordance with the plywood standards ( JAS and ASTM) the properties tested were density,moisture content, bending strength, tensile strength, compression strength , and moisture resistant. Bonding strengththe results showed that all kinds of wood species combination could be made for laminated veneer glued with urea formaldehyde without any difficullty. The density of laminated veneer was higher than an average veneer density of single. wood species or an average veneer density of mixed wood species. The mechanical properties of laminated veneer increased as the densily of laminated veneer increased and the relationship could be expressed by linear regression equations. As a result, some laminated veneer properties could be estimated from its density without considering its wood species.

Abstract

The objectives of the study was to determine the effect of phoxim on the properties of rubber wood particleboard (Hevea brasiliensis ) phoxim concentration used were 0.05,1, 1.5 and 2 % based on particle dry weight.The result showed, that the addition of phoxim preservative to particleboard reduced the values of modulus of rupture, modulus of elasticity, internal bond strength and shear strength, but increased the thicknees swelling and water absorption of particleboard. However, the phyrical. and mechanical properties of particleboard treated With phoxim preservative up to 2 % met the FAO standard for medium density particleboard and met JIS for type 150 particleboard. Compared with Indonesian standard all particleboards produced met the standard requirements except for internal bond strength.

Abstract

Besides being used as raw material for food industries sago flour has also been know as a staple food in riau province. The utilization of sago for industrial input as well as for staple food will encourage the development of agro based industry wich in turn would lead to the improvement of sago farmer’s income.Based on this study,cost of sago plantation, harvesting and transportation of sago stem to the processing plant was Rp 1.074.500,- per ha absolute margin received by farmer amounted Rp. 119.187,50 per ha per year (rotation period was 8 years)Average processing costs of converting saho stem to sago flour amounted to Rp. 256.685,- per ton (wet sago flour) so that absolute margin received by sago processing plant in average was Rp. 134.315,- per ton, while the selling price at factory in Cirebon was Rp. 425.000,- per ton sago flour.Benefit cost ratid analysi show that net benefit cost ratio 1.33 and gross benefit cost ratio 1.44 and profitability ratio 1.61 show that further development of sago utilization in riau provice is economically feasible.

Abstract

The objective of this study is to find optimal allocation of round wood raw material used by teak sawmill, so as to minimize cost of raw materialThe result of linear programming analysis shows that, in 1991 the optimal cost of raw material at Brumbung teak sawmill was Rp 9,992,759,165. Using this optimal raw material allocation scheme, Brumbung teak sawmill could decrease raw material cost about Rp 390,573,835 in 1991.

Abstract

This paper deals with an experiment investigating the effect of presteaning time on the properties of medium density fibreboard. The boards were made of 15 wood species mixtures with an equal weight proportion of four specific gravity groups i,e 0.31 – 0.45; 0,46 – 0,60; 0,61 – 0,75; and 0.76 – 0.90.Pulp preparations were carried out by using thermo mechanically at 4 kg/cm2 for 10, 15 and 20 minutes and refined for 10 minutes. The sheets were formed by using the laboratory wet felting process. Cold pressing ( room temperature) and hot pressing (170°C) were conducted at 45 kg/cm2 for 5 minutes and 20 kg/cm2 for 40minutes, respectively.The experiment’s result also showed that the tensile strength parallel to surface, modulus of rupture, modulus of elasticity. Density, water absorption, thickness swelling and volume swelling of fiberboard were not significantly affected by the presteaming time, specific gravity and interaction of the both factors. It was also reviewed that an increasing specific gravity tended to lower the intodulus of rupture, tensile strength parallel to surface and modulus of elasticity, and tended to increase thickness swelling, volume swelling and water absorption.In general , the properties of the medium density fibreboard (density, water absorption, modulus of rupture and modulus of elasticity) are comparable to those of the FAO standard requirements, but the tensile strength parallel to surface is tess than that of the FAO standard.

Abstract

The utiliization of wood for cooling tower in Indonesia tends to increase and has become more important. Wood as material for cooling tower has been applied commercially in several developed countries such as New Zealand,USA and Japan. While in indonesia it has just been started in 1981 after the establishment of Kamojang Geothermal Power Station Unit 1. This paper deals with some experience in treating keruing wood (Dipterocarpus spp.) as material for cooling tower by vacuum-pressure impregnation. The result shows that keruing is easy to treat. In other to meet the retention of 24 kg/m3, the concentration of the solution must be at least 6.25 percent and absortion of 384 liters of preservative per cu.m.

Abstract

Jackfruit plant (artocarpus heterophyllus lamk) is know as multipurpose tree. A chemical analysis of jackfruit wood from west java has been conducted to determine the contents of cellulose, lignin, pentosan,ash,silica and solubility in cold water, hot water, one percent sodium hydroxide and alcohol-benzene (1:2).The results showed that cellulose content 56,47 percent, lignin 28,76 percent, pentosan 18,64 percent, ash 0,78 percent, and silica 0,37 percent. Thesolubility in cold water 12.29 percent, hot water 14,41 percent, one percent sodium hydroxide 24,70 percent, and solubility in alcohol-benzene (1:2) 10,78 percent.

Abstract

Moulding products made of two wood species in the form of coves were treated with BFCA preservative by cold soaking. The length of the test pieces were 30 cm. The duration of cold soaking treatment were 2, 4, 6 and 8 days, with preservative concentrations of 5 and 10 percent. The test results, after taking both retention and penetration requirements into consideration for wood uses under roof and in the open air without ground contact, showed that both wood species could be satisfactorily treated under experimental conditions. The treatment schedules proposed for both species are also presented in this paper. The average swelling of those species after treatment comparing to dimension are relatively small, therefore could be avaidable and has no affect on their use.
