"ABSTRAKModa transportasi di Indonesia terus mengalami perubahan dan perkembangan seiring berjalannya waktu. Sepeda motor di darat telah mengalami perubahan sedemikian rupa sehingga dapat membawa barang dengan jumlah tertentu. Maka dari itu, moda transportasi praktis seperti ini juga harus ada pada transportasi air. Jetski yang kita kenal sebagai sepeda motor air dimodifikasi sedemikian rupa sehingga dapat memuat berbagai kebutuhan logistik dengan jumlah tertentu. Dengan menggunakan lambung pelat datar semi-trimaran dan motor tempel sebagai penggerak, proses produksi akan jauh lebih cepat dan biaya tak terlalu mahal. Penamaan dari transportasi baru ini adalah Boatski.

ABSTRACTMode of transportation in Indonesia has change and develop over time. Motorcycles on land have undergone such changes that they can carry a certain amount of goods. Therefore, such practical transportation modes must also exist in water transport. Jetski that we kno as a motorcycle at the water is modified in such way that it can contain a variety of logistical needs with a certain amount. By using a semi trimaran flat surface hull and outboard engine as a propeller, the production process will be faster and the cost is not too expensive. The naming of this new transportation is Boatski."

"Hydrofoil adalah teknologi untuk menambah efisiensi energi dengan menghasilkan gaya angkat untuk mengurangi hambatan lambung kapal. Namun pada kecepatan rendah hambatan hydrofoil yang dihasilkan lebih besar dibanding tanpa hydrofoil. Pada penelitian kali ini kapal yang digunakan merupakan kapal patroli pelat datar. Hambatan kapal pelat datar lebih besar dibanding kapal streamline pada umumnya, hydrofoil menyebabkan hambatan oleh lambung kapal tidak dominan karena fluida yang melewati lambung merupakan fluida udara. Penelitian ini membahas proses perancangan hydrofoil untuk kapal pelat datar dan pengujian menggunakan metode eksperimen. Eksperimen dilakakukan di air tenang dengan penggerak dari RC boat engine, parameter pengukurannya adalah waktu dan jarak untuk mendapatkan kecepatan pada setiap kondisi. Pada penelitian ini didapatkan perbandingan kecepatan kapal dengan dan tanpa hydrofoil menggunakan power yang sama. Pada kecepatan rendah hydrofioil justru memberikan kerugian dan pada kecepatan tinggi dapat menambah kecepatan.

Hydrofoil is a technology to increase energy efficiency with producing lift force to decrease hull ressistance. But in low speed, ressistance with hydrofoil is higher than without hydrofoil. In this research, flat plate hull patrol boat will be used. The ressistance of flat plate hull in general is higher than streamline hull. Hydrofoil can cause hull ressistance not dominant anymore because the hull ressistance will only caused by air fluid.

This research discuss about process of hydrofoil design for flat plate hull and will be tested with experiment methode. The experiment is hold in steady water with RC boat engine to run the boat, measurement paramater of this research is time and distance to calculate speed in each condition.

Output of this research is speed efficiency between model boat with and without hydrofoil. At low speed, hydrofoil gives disadvantage for speed efficiency, and at high speed, it gives advantage for speed efficiency."
