The use of bamboo slats laminate as a renewable construction material for East Java traditional fishing boat

Today marine fisheries in Indonesia are still mostly carried out using traditional fishing boats. Traditional fishing boats are vessels built from solid teak wood with a capacity of up to 20 GT with manually operated fishing gear. It is estimated that overall the number of traditional fishing vessels reaches 518,746 units operated by almost five million fishermen. In an effort to at least maintain and subsequently increase the number of traditional fishing vessels, the availability of solid wood as a basic material is required. However, nowadays fishermen face the problem of solid wood scarcity as a material for reparations and the construction of new boats. In order to solve this problem, research has been carried out on the use of bamboo slats laminate as a substitute for solid wood. The output of this study shows that the laminated material of the bamboo slats has mechanical properties that meet the classification requirements for ship construction. This material has been applied to traditional 2 GT capacity fishing boats operated in Blitar Beach, East Java. This study shows that lamination of bamboo slats can simplify the process of forming traditional fishing boat scantling elements, speed up production time by 33.33%, and reduce construction costs by 35.05%; smaller size of structural components makes the weight of the structure lighter. So that for the same draft, it will increase payload by 189.35% compared to boats made from solid teak wood. If the payload is considered the same, then this traditional boat made from bamboo laminate can reduce its engine power by 25.7%. Ultimately, the development of laminated bamboo boats is believed to have potential in supporting the business continuity for traditional fishermen at lower levels.
