Abstract

Natuna is one of the regencies in the Riau Archipelago Province, the area of Natuna Regency is 224,684.59 km2 with a land area of 2,000.85 km2 and an ocean area of 222,683.74 km2. According to the Ministry of Maritime Affairs and Fisheries, Natuna occupies the first position for the purpose of exporting fishery products from the SKPT location (Integrated Marine and Fishery Centers in Small Islands and Border Areas), namely marine fisheries resources reaching more than 1 million tons per year. The extent of Natuna waters and the large potential of existing capture fisheries resources cause the Natuna waters to be included in the Fisheries Management Area (WPP 711) which is prone to illegal fishing activities. It has been proven recently that in the waters of North Natuna there are coast guard ships from foreign countries escorting fishing vessels belonging to their countries that are carrying out illegal, unreported, and unregulated fishing activities. The purpose of this research is to design a patrol ship to carry out security missions around the Natuna waters. The method used in this design is the Parent Design Approach method. This method is known in designing ships, namely by taking a comparison ship that has the same characteristics as the ship to be designed. The main dimensions of the ship obtained in this final project are Lwl = 50.2 m, B = 9.32 m, H = 4.45 m, T = 3.5 m, Vs (max) = 25 Knots, Crew = 40 Indonesian navy. Armaments used on this ship are Oto-Melara 76/62SR 76 mm, Oerlikon Millennium 35 mm, RWS Machine Gun, and SS1-V1 Kal hand rifle. 5.56 mm.

Abstract

Generally, the planning of the material arrangement of the aluminum hull plate is always carried out at an early stage to obtain a material formation that has good economic value. One of the strategies used to obtain economic value in shipbuilding is the use of various grades of plate material. The grade of aluminum material that is often used on ships is the 5xxx series. Where this series has many grades that can be used as ship hull material options. The price difference for each grade of aluminum material for ships is a very influential variable on the economic value of shipbuilding. However, before being applied to shipbuilding, it is necessary to test the feasibility of aluminum plate connections with variations in plate grade. The aim is to provide clear information regarding the technical feasibility of selecting material grades. Therefore, in this study, a simulation will be carried out to test the strength of the plate connection with variations in the grade of aluminum material using the experimental method. The plate joint test is carried out using only the Tensile test in the laboratory with reference to the ASTM rules. The grades of aluminum plate materials used are 5052 and 5083. Connection formations are between 5052-5052, 5083-5083, and 5052-5083. From the test results, the largest average yield stress value is 202.34 N/mm2 at the variation 5083-5083, the maximum average ultimate stress value is 261.70 N/mm2 at the variation 5083-5083. For the variation of the 5052-5083 plate connection, it still has a yield stress value that is greater than the basic yield stress of the material, namely 142.97 N/mm2. Where the percentage value of the achievement level of yield strength is 113.6% of the basic yield stress value of the material based on BKI rules. However, in achieving the ultimate stress value, it is still lower than the ultimate basic stress of the BKI rules standard material, which is 193.88 N/mm2. Where the percentage value of the level of ultimate strength achievement is 70.5% of the ultimate basic stress value of the BKI rules standard material.
