Abstract
Propeller coating bukanlah konsep baru, beberapa percobaan telah terjadi sejak awal Perang Dunia II namun tidak ada tindak lanjut yang dibuat pada percobaan.Akibatnya, tidak banyak yang telah dipublikasikan dalam literatur terbuka mengenai lapisan baling-baling.Sedangkan, lapisan baling-baling memberikan perlindungan terhadap erosi kavitasi dan korosi sambil memberikan permukaan baling-baling halus yang memiliki drag hidrodinamik lebih rendah (Dashnaw dkk,1980).Di Indonesia masih sedikit yang menerapkan propeller coating yang ada di galangan. Karena mereka hanya fokus pada lambung. Jika propeller coating ini diterapkan maka tentunya akan mengurangi kavitasi pada propeller.Percobaan dilakukan pada prototype, percobaan dilakukan dengan cara memasang propeller pada poros yang berada pada flow channel di laboratorium. Pada pelaksanaan percobaan ada yang pelru diperhatikan diantaranya :komponen yang ada saat dilakukan percobaan dan variabelnya yaitu putaran potensiometer. Dari hasil percobaan propelleruncoating dan coating yang dilakukan di Flow ChannelLaboratory of Marine Machinery Fluid pada percobaan tersebut tidak ada fenomena kavitasi baik pada putaran tinggi dan rendah karena ada beberapa indikator seperti pressure, temperature dan kecepata aliran yang tidak bisa diatur sebelum percobaan berlangsung.Perbedaan antara uncoating dan coating tidak terlalu signifikan. Secara keseluruhan perbedaan yang diperoleh dalam perobaan berlangsung 3% antara uncoating dan coating. Untuk propelleryang mengalami kavitasi bisa dilakukan coating untuk menguranhi kavitasi meskipun pada akhirnya performanya turun.

The propellers lay in a new concept, several experiments have taken place since World War II but no one has experimented. Summary, not many have used propeller layers. Whereas, the propeller layer provides flexibility to cavitation and corrosion erosion while providing a smooth vane surface with lower hydrodynamic barriers (Dashnaw et al, 1980). In Indonesia there are still few who apply the propeller coating in the shipyard. Because they only focus on the stomach. If the vane layer is processed then the sesame will reduce the cavitation on the propeller. The experiments were carried out on the prototype, the experiment was carried out by mounting the propeller on the axis located on the flow channel in the laboratory. At the same time, the current components are experimental and the variables are potentiometer rotation. From experimental propeller uncoating and coatings conducted at Flow Channel Laboratory of Marine Machinery Fluid in the experiment there is no very high phenomenon and there are several factors such as pressure, temperature and flow rate that can not reach before the experiment takes place. The difference between uncoating and coating is not very significant. The overall value obtained in the trials lasts 3% between uncoating and coating. For cavitation propellers a coating can be used to reduce cavitation even though ultimately its performance decreases.
