Abstract

Sampah dan polusi udara yang berasal dari kendaraan bermotor telah menjadi sebuah masalah besar di berbagai kota besar. Limbah dapat diproses menjadi energi listrik dengan teknologi fisika plasma dan untuk mengurangi ketergantungan pada sewa lahan yang mahal pada lingkungan perkotaan maka kapal dapat dimanfaatkan sebagai struktur bangunan terapung di atas laut. Menggunakan metode deskriptif analitik dan desain kebutuhan kapal terapung didapat kalkulasi yang diestimasikan dari energi listrik yang dapat dihasilkan dari 11.686,56 ton sampah/hari adalah 581,306 MW, yang mana dapat mencukupi 15,5%  dari listrik di wilayah DKI dimana total kapasitas terpasangnya adalah 3748,40 MW.

Abstract

Efficient propeller performance contributes to better overall ship performance and speed. A well-designed propeller can optimize thrust generation, leading to improved maneuverability, responsiveness, and acceleration. It enables ships to maintain higher speeds while using less power, enhancing their competitiveness in the maritime industry. In this study, the Kaplan series propeller was analyzed by using Computational Fluid Dynamics (CFD). By modifying the angle of attack on the Kaplan propeller with 3, 4, and 5 blades, the distribution of the surface pressure, generated thrust, and torque value were easily identified and analyzed. The result shows that the change in the angle of attack influenced the pressure distribution on the back and face side of the propeller. The angle of attack is increased, and the pressure surface distribution also tends to increase. It has also affected the efficiency of the propeller performance which is expressed by the values of thrust propeller and torque. The more efficient the propeller performance, the less power it requires to produce the desired thrust.

Abstract

For variations in ship speed given data such as length perpendicular (LPP) 28 meters, propeller rotation (N) 290 rpm and shaft horse power (SHP) of 452.5 Hp by setting speed values varying from 4 knots to 9 knots, the average propeller efficiency for the B4-40 type is 60% while the average trust or thrust of the ship is 5873.5 kg and the average trust coefficient is 0.28. Likewise for the B4-55 type, the average propeller efficiency is around 58.6%, then the average thrust for the ship is 5736.3 kg and the thrust coefficient for the ship is 6.6.
