Abstract

During the past time the utilization of palm oil tree only limited to producing fruit to produce oil with all their derivatives, as well as the utilization of  husk and midrib. Stem, as the biggest mass palm oil tree has not been used commercially due to its lack of quality. One effort in improving quality of palm oil wood is compregnation. Compregnation interpreted as an effort of putting the chemicals into wood structure using prresure. Chemicals that can penetrate into wood structure in this case is melamine formaldehyde resin. The result of research showed that compregnation palm oil wood by melamine formaldehyde increased the specific of gravity of wood from 0,32  before compregnation to 0,48, 0,58 and 0,65 for 50%, 75% and 100% concentrate. Moisture content decreased from 12,05% before compregnation to 10,67 at 100% concentrate. MOR increased  from 64,58 kg/cm2 before compregnation to 131,54 kg/cm2, 188,94 kg/cm2 and 361,14 kg/cm2 each for 50%, 75% and 100% concentrate.

Abstract

Indonesia is a tropical country that has various types of wood. However, the supply of wood time to time is decreasing, while in construction the demand for wood is increasing. This increase has resulted in massive exploitation of the forest, so that the availability of large diameter timber from natural forests is increasingly limited. The use of wood that has a shorter cutting age (10-15 years) and has a small diameter is not efficient as a structural or construction component. The technology used is a structural form that does not come from whole wood but rather a laminated component that is made through a bonding process. This study aims to determine the shear strength of solid testing, solid coating testing, lamination testing, and coating lamination testing. The wood used in this study is acacia crassicarpa wood and the adhesive used is epoxy adhesive. The adhesive weight used was 50 MDGL (Multilayer Double Glue Line). From the test for testing the solid shear strength is 4,01 MPa, the shear strength of the laminate is 2,10 MPa, the shear strength of the solid coating is 3,37 MPa, the shear strength of the coating laminate is 2,83 MPa.Key words: Laminate beam, acacia crassicarpa wood, shear strength, epoxy adhesi.

Abstract

In this paper, to strengthen the connection between wood joints is conducted by the use of combination of bolt and epoxy adhesives. There where three variations of connection observed in this study e.g; U1, U2, U3. U1 was using a bolt connecting device. U2 was using a bolt connectors which is reinforced with epoxy adhesive on the bolt hole. U3 was using a bolt connectors which is reinforced with 40 MDGL epoxy adhesives in the joint slice plane. The result of this study indicates that the bolt connection yielding mode is theoretically as same as the yielding mode that occurs in the result of laboratory testing, named mode IIIs. The lateral resistance of bolt joints form laboratory tests result is 108% greater compared to the lateral resistance of bolt joints theoretically. The addition of epoxy adhesive to the bolt hole does not provide the real reinforcement of the joint extension of Ulin Woods with bolt connecting tools. The addition of epoxy adhesives with the amount of 40 MDGL in the joint slice plane, provides 16.6% reinforcement on the joint extension of Ulin Woods with bolt joint tools.Keywords: reinforcement joints, bolt joints, epoxy adhesive joints, lateral resistance
