Abstract
HYDROCONTEST merupakan perlombaan kapal cepat dan efisien antar mahasiswa di tingkat internasional dalam format race menggunakan kapal yang didesain, diteliti, dan diproduksi sendiri oleh para mahasiswa. Melihat persaingan dan iklim riset dalam perlombaan serta berdasarkan hasil evaluasi dari keikutsertaan tim HYDRONE ITS dalam HYDROCONTEST 2017, dalam Tugas Akhir ini akan didesain sebuah kapal fast displacement yang akan digunakan untuk dua kategori perlombaan: Lightweight Race (waktu tercepat) dan Long-Distance Race (jarak tempuh terjauh) dalam HYDROCONTEST 2018. Proses desain kapal dalam Tugas Akhir ini akan dititikberatkan pada aspek performa kapal khususnya hambatan dan propulsi kapal agar kapal dapat memperoleh peringkat yang baik dalam kedua kategori perlombaan. Dilakukan analisa hambatan dengan software CFD pada beberapa variasi bentuk haluan lambung yaitu conventional bow, vertical bow, dan axe bow serta analisa pengaruh variasi panjang kapal 1.9 m, 2.2 m, dan 2.5 m terhadap hambatan kapal. Hasil analisa menunjukkan model kapal dengan axe bow memiliki hambatan terkecil dan model dengan panjang 2.5 m memiliki hambatan yang lebih kecil dibandingkan dengan panjang 1.9 m dan 2.2 m meskipun selisih hambatan dengan model 2.2 m sangat kecil. Menggunakan data open water test propeller, data hambatan kapal, dan data komponen elektrik, dilakukan optimisasi pitch dan RPM propeller sehingga kapal dapat mencapai kecepatan maksimum 5.25 m/s dan jarak tempuh terjauh sepanjang 24 kali panjang lintasan dalam waktu satu jam.

HYDROCONTEST is an international fast and efficient boat competition between students in the form of race using boats designed, researched, and produced by the students themselves. Considering the advance and the research atmostphere of the competition and based on the evaluation of Hydrone ITS team’s participation in HYDRCONTEST 2017, a design of fast displacement ship is created for two categories of competition: Lightweight Race (fastest time trial) and Long-Distance Race (farthest distance). The design process in this final project is focused on the performance of the ship especially the resistance and propulsion so the ship would achieve good position in both categories of competition. Resistance analysis with CFD software has been done on several types of bow such as conventional bow, vertical bow, and axe bow. Analysis also has been done to find of the effect of ship’s length of 1.9 m, 2.2 m, and 2.5 on the resistance of the ship. Results show that the model with axe bow has the lowest resistance and model with 2.5 m length has lower resistance than of the 1.9 m and 2.2 m model even though the resistance difference with the 2.2 m model is slight. Using the data of propeller’s open water test, ship’s resistance, and electrical components, propeller’s pitch and RPM has been done so the ship will achieve 5.25 m/s of maximum speed and 24 laps of the track course in one hour for maximum distance.
