Abstract

Barunastra ITS Team merupakan tim riset ITS yang berfokus pada riset roboboat autonomous surface vehicles. Pada bulan Juni tahun 2019 ini akan mengikuti International Roboboat Competition di Florida, Amerika Serikat. Tim barunastra ITS memiliki problem pada berat kapal sehingga untuk menunjang kebutuhan displacement massa kapal diatasi dengan dinaikannya dimensi kapal. Maka dari itu diperlukan pengembangan bahan bahan dan metode untuk pembuatan hull kapal untuk mampu mereduksi berat. Sehingga dilakukan penelitian terkait desain hull, bahan hull, dan proses produksi hull. Dari hasil penelitian yang telah dilakukan maka dapat diperoleh dimensi hull yang mempu menghasilkan buoyancy sebesar 21 kg memiliki dimensi sebagai WL length (LWL): 882 mm, beam max extends : 491 mm, height of the ship: 300 mm, draft amidships : 150 mm, wetted area : 579000 $mm^2$, prismatic coefficient (Cp) : 0,836, block coefficient (Cb): 0,575. Penelitian pada bahan berdasarkan hasil pengujian three point bending pada massa fraksi fiber 40% didapatkan nilai kekuatan bending pada lapisan 2 layer maksimal sebesar 245,828 MPa, pada lapisan 3 layer didapat kekuatan bending maksimal sebesar 249,299 Mpa, dan pada lapisan 4 layer didapat kekuatan bending maksimal sebesar 283,640 Mpa. Pada simulasi yang dilakukan dengan menggunakn software Ansys didapat Equivalent Stress maksimum ketika kapal bergerak maju dengan kecepatan 1m/s dengan nilai sebesar 130,04 Mpa. Sehingga layer optimum adalah 2 lapis. Proses produksi hull kapal dengan menggunakan bahan fiber carbon twill dan epoxy resin dengan metode vacuum bagging memerlukan tahap-tahap pembuatan master model hull, pembuatan mold hull, proses fabrikasi part Hull, penyambungan part hull, uji kebocoran pada hull, proses coating hull.

ITS Barunastra Team is an ITS research team interested in research on roboboat autonomous surface vehicles. In June 2019 this will take part in the International Roboboat Competition in Florida, United States. ITS Barunastra Team has problems with the weight of the ship so that to support the mass transfer needs of the ship is overcome by the dimensions of the ship. Therefore, it is necessary to develop materials and methods for making hull vessels to be able to reduce weight. Related to the research is related to hull design, hull material, and hull production process. From the results of research that has been done, the dimensions of hull can be obtained which can produce buoyancy of 21 kg with dimensions of WL (LWL): 882 mm, elongated max beam: 491 mm, ship height: 300 mm, concept in the middle of the ship: 150 mm, area wet: 579000 $mm^2$, prismatic coefficient (Cp): 0.836, block coefficient (Cb): 0.575. The research on the material based on the results of testing of three bending points at 40% fiber mass fraction obtained the maximum flexural strength of layer 2 layer of 245,828 MPa, the maximum layer strength of 249,299 Mpa, and the maximum flexural strength of 283,640 MPa. In the simulation using software, Ansys gets stress equal to maximum compress, the ship moves forward at a speed of 1 m / s with a value of 130.04 Mpa. The optimal layer is 2 layers. The ship hull production process using twill carbon fiber and epoxy resin by vacuum bagging method requires the manufacture of a master hull model, hull mold making, Hull part fabrication process, hull section junction, hull solution testing, hull coating process.
