Abstract
Optimasi performance hidrodinamik propeller sebagai penggerak kapal, dapat dioptimasikan dengan tetap memperhatikan batasannya. Parameter yang dapat dioptimasikan antara lain diameter, putaran, jumlah daun, advance coefficient, pitch-diameter ratio, blade area ratio, Reynolds number, dan thickness-cord ratio sedangkan batasan desainnya diantaranya adalah kekuatan material yang cukup, tidak menimbulkan kavitasi dan getaran, tidak menyebabkan erosi. modifikasi desain propeller B-series dilakukan pada parameter minor dan mayor. modifikasi minor, mempunyai keutungan bahwa data uji coba B-Series valid digunakan. Pendekatan Desain dengan mengoptimasikan distribusi ketebalan foil tiap segmen adalah jenis modifikasi minor, dengan cara mencari propeller base yaitu B-series, kemudian dari data foil itu kita optimasikan distribusi ketebalan foilnya tiap segmen, dengan mempertahankan panjang foil dan ketebalan minimal, ketebalan maksimal foil. Optimasi distribusi ketebalan foil tiap segmen, menggunakan bahasa pemrograman RUST, dengan input foil base NACA 66. Sedangkan Panjang foil, ketebalan foil dari data propeller yang terpilih B4-85. Optimasi otomatis distribusi ketebalan foil ini dilakukan dengan algoritma yang telah dibuat pada RUST dan solfer Performance foil menggunakan software XFoil. Dari hasil perbandingan performance foil tiap segmen B4-85 dan NACA 66 Modifikasi, didapatkan hasil; pada r/R 0.2 cl/cd B4-85 sebesar 4.2 dan pada NACA 66 MOD Sebesar 77.3. Pada r/R 0.3 cl/cd B4-85 sebesar 24.2 dan pada NACA 66 MOD Sebesar 26.9. Pada r/R 0.4 cl/cd B4-85 sebesar 0.5 dan pada NACA 66 MOD Sebesar 230. Pada r/R 0.5 cl/cd B4-85 sebesar 2.3 dan pada NACA 66 MOD Sebesar 123. Pada r/R 0.6 cl/cd B4-85 sebesar 1.1 dan pada NACA 66 MOD Sebesar 105. Pada r/R 0.7 cl/cd B4-85 sebesar 0.5 dan pada NACA 66 MOD Sebesar 80. Pada r/R 0.8 cl/cd B4-85 sebesar 1.6 dan pada NACA 66 MOD Sebesar 6.4. Pada r/R 0.9 cl/cd B4-85 sebesar 0.22 dan pada NACA 66 MOD Sebesar 2.59

Optimization of propeller hydrodynamic performance as a ship propulsion optimized while taking into account the limitations. Parameters that can be optimized include diameter, rotation, number of leaves, advance coefficient, pitch-diameter ratio, blade area ratio, Reynolds number, and thickness-cord ratio while the design limitations include sufficient material strength, does not cause cavitation and vibration, does not cause erosion. modification B-series propeller design is carried out on minor and major parameters. modification minor, has the advantage that valid B-Series trial data is used. Design approach by optimizing the thickness distribution of each foil segment is a type of minor modification, by looking for a propeller base ie B-series, then from the foil data we optimize the foil thickness distribution each segment, while maintaining minimum foil length and thickness, maximum foil thickness. Optimization of foil thickness distribution for each segment, using the RUST programming language, with a NACA 66 base foil input. While the length of the foil, the thickness of the foil from the selected propeller data is B4-85. The automatic optimization of the foil thickness distribution is carried out by an algorithm was made on RUST and Solfer Performance foil using software XFoil. From the results of a comparison of the performance foil of each segment B4-85 and NACA 66 Modifications, results obtained; at r/R 0.2 cl/cd B4-85 of 4.2 and at NACA 66 MOD of 77.3. At r/R 0.3 cl/cd B4-85 it is 24.2 and at NACA 66 MOD Of 26.9. At r/R 0.4 cl/cd B4-85 is 0.5 and at NACA 66 MOD of 230. At r/R 0.5 cl/cd B4-85 of 2.3 and at NACA 66 MOD of 123. At r/R 0.6 cl/cd B4-85 of 1.1 and at NACA 66 MOD of 105. At r/R 0.7 cl/cd B4-85 of 0.5 and at NACA 66 MOD of 80. At r/R 0.8 cl/cd B4-85 of 1.6 and at NACA 66 MOD Of 6.4. At r/R 0.9 cl/cd B4-85 is 0.22 and at NACA 66 MOD
