The 2nd International Seminar on Science and Technology 109 August 2nd 2016, Postgraduate Program Institut Teknologi Sepuluh Nopember, Surabaya, Indonesia The extent of the area under the curve of GZ on a roll are: angle of 0° - 30° should not be less than or equal to Advantages of HDPE material in manufacturing boats a. - HDPE is highly durable against aging and corrosion material (minimum last 50 years), the durability of b. HDPE boats are longer than other boats made of other materials. - Durability rift good meaning it has little damage. c. - HDPE is flexible and durable, resistant to the worst weather conditions. - It is easier to assemble than the HDPE material 2. compared to steel, wood, aluminum or other composite materials. - Polyethylene has the advantage of anti-corrosion. 3. - Non-toxic and easy to clean. - Vessel HDPE does not need paint or any treatments. - Resistant to ultra violets, stable, fire-resistant and low 4. TABLE 1. 0.055 m.rad. The extent of the area under the curve of GZ on a roll angle of 0° - 40° should not be less than or equal to 0.090 m.rad. The extent of the area under the curve of GZ at an angle of roll 30° - 40° should not be less than or equal to 0.030 m.rad. IS Code 2008 The maximum GZ value that occurs at an angle of 30 ° - 180 ° can not be less than or equal to 0.2 meters. Section A.749 (18), Chapter 3.1.2.3 Angle at maximum GZ value should not be less than or equal to 25° Section A.749, Chapter 3.1.2.4 PROPERTIES MATERIAL OF HDPE PLASTIC maintenance cost - 100% recyclable. GM initial value at an angle of 0° can not be less than or equal to 0.35 meters. Calculation of the stability of fishing vessels can be calculated using the equation according to the approach of "Huseyin and Abdi (1999)" as follows: II. METHOD A. Design fishing vessel of pompong plastic HDPE Research conducted centrally located in Bengkalis area of Riau, with the capacity needed to fulfill the local fisherman's needs. Then, planning is done followed by the design and depiction of ships pompong made of HDPE. The depiction of the model pompong HDPE using maxsurf and Auto CAD software. B. Stability of the ship The stability of the ship is a vessel's ability to return to its original position due to waves or other external forces. Generally, vessels must meet the standards of the safety of shipping (safety of life at sea) and passengers comfort on the stability of the ship. Stability criteria used is the International Maritime Organization (IMO). The criteria of the International Maritime Organization (IMO, 1977) was used for the fishing boats as follows: 1.
