| Popis: | The significant increase of Teak wood price causes the high price of fishing vessels made from intact Teak wood so that it is necessary to replace the Teak wood as the main material in fishing vessels. The traditional construction of fishing vessels has negative impact such as decreasing quality of the material due to heat treatment of wood, so that laminated wood technology with cold treatment is one solution to maintain and strengthen wood material. Mahogany wood is one of the woods that can be used as an alternative material for fishing vessels according to the Indonesian Classification Bureau, but some people assume that Mahogany is not suitable as an alternative for Teak wood due to differences in the durability of wood in seawater, so the research will be conducted on lamination of Mahogany and Teak as a material to build fishing vessel. This study carried out tensile and bending tests in accordance with ASTM standards for laminated material. Based on the results of test, the laminated material of Mahogany and Teak has an average tensile strength of 96.56 MPa, bending strength of 72.38 MPa and specific gravity of 0.82 gr/cm2. According to the regulations of the Indonesian Classification Bureau the laminate material of Mahogany and Teak meets minimum tensile strength and bending strength, equivalent with Strength Group II-III and can be used for the entire construction section of the fishing vessel. From the economic aspect it is estimated that the cost to build a 3 GT fishing vessel around IDR 44,927,656 (USD 3,160). |
