Abstract

Iron wood (Eusideroxylon zwageri), bengkirai wood (Shorea laevifolia endert), and red meranti wood (Shorea leprosula) used as a basic material in the manufacture of a ship. The wood used is enters the class of wood that is strong and durable, so it can survive in water. The use of wood as the hull of the ship is often damaged by attacks by marine animals such as barnacles and sea worms. Barnacles attached to the bottom of the ship resulting in reduced ship speed, while the shipworm larvae would make holes in the wood and make it brittle. The goal in this study is to analyze the intensity of damage to Ironwood, bengkirai wood and red meranti wood from attacks by wood-destroying organisms to determine which type of wood is better for use in shipbuilding. The test method was conducted using SNI 01-7207-2006. The wood sample is formed 30 cm x 2.5 cm x 5 cm and the middle is made a hole with a diameter of 1.5 cm. The sample is connected with a cable rope with a distance of 5 cm using a pipe. The sample is tied to the pier pole at low tide. Wood tested included in the category of highly resistant to attack barnacle organisms with an intensity of attack on each Wood <7%. Meranti test wood samples exposed to sea worm attacks with intesitas attack 33.3% - 56.6%, so this type of wood is considered less resistant to attack.Kayu ulin (Eusideroxylon zwageri), kayu bengkirai (Shorea laevifolia endert), dan kayu meranti merah (Shorea leprosula) dimanfaatkan menjadi bahan dasar dalam pembuatan sebuah kapal.
