Abstract

Sebuah kapal berjalan dengan menggunakan suatu daya dorong yang dalam istilahnya disebut sebagai thrust. Daya dorong tersebut dalam menggerakkan kapal akan sangat dipengaruhi oleh tahanan kapal. Tahanan (resistance) atau disingkat R kapal adalah gaya fluida yang bekerja pada kapal sedemikian rupa melawan gerakan kapal tersebut. Tahanan di sini sebagaian besar di pengaruhi oleh tahanan gesek kapal. Superhydrophobic adalah sifat fisis molekul suatu material untuk menolak atau menghindari air. Seperti air diatas daun talas yang terlihat tidak sedikit pun membasahi daun tersebut. Itulah yang disebut Hydrophobic Efect. Tujuan penulisan skripsi ini menganalisa dan membuktikan apakah jika lambung (hull) kapal dilapisi dengan superhydrophobic akan terjadi pengurangan tahanan. Metode yang digunakan ialah dengan melakukan eksperimental langsung pada lab hydrodinamika ITS. Dari hasil analisa didapatkan tahanan yang di hasilkan dari model setelah dilakukan pelapisan mengunakan hydrophobic dan superhydrophobic berkurang. Pengurangan tahanan setelah di lapisi superhydrophobic rata-rata sebesar 10% dan 22%. Pengurangan tahanan gesek terjadi seiring dengan turunnya tahanan total ==================================================================================================== A ship runs by using an impetus which the term referred to as thrust. The thrust in moving the ship will be strongly influenced by the detention of the ship. Resistance (R) boat is fluid force acting on the vessel in such a way against the movement of the ship. Resistance is a large part influenced by the frictional resistance of the ship. Superhydrophobic is the physical properties of the molecules of a material to reject or avoid water. As above water taro leaves that look the slightest wet the leaves. That is called Hydrophobic-effect. The purpose of this thesis to analyze and prove whether if the hull (hull) vessel is coated with a superhydrophobic will be a reduction of resistance. The method used is to conduct experimental lab hydro-dynamics on ITS. From the analysis results obtained custody which is derived from the model after using hydrophobic and superhydrophobic coating is reduced. Reduction in the coated superhydrophobic custody after an average of 10% and 22%. Reduction of frictional resistance occur along with lower total resistance
