Abstract
Rendahnya effisiensi dari pemanfaatan energi hasil pembakaran pada kendaraan mendorong dilakukannya penelitian yang berfokus pada energy harvesting. Pada penelitian kali ini dirancang Regenerative Shock Absorber (RSA) baru yang bernama Hydro-Magneto-Electric Regenerative Shock Absorber ( HMERSA) dengan dual input-single output, dimana aliran fluida dari dua HMERSA akan digabungkan untuk menggerakkan satu motor hidrolik yang terkopel dengan generator. Sistem HMERSA dual input-single output tersebut akan diaplikasikan pada bagian belakang kendaraan, dimana kendaraan dimodelkan dengan sistem setengah kendaraan. Input yang digunakan dalam tugas akhir ini adalah input sinusoidal dan step. Pengaruh keterlambatan dari salah satu HMERSA akan dianalisis dengan menvariasikan beda fase dari input sinusoidal yang diberikan. Dari penelitian ini diperoleh gaya redam dan energi bangkitan terbesar terjadi ketika kedua silinder hidrolik bergetar dengan beda fase 0º . Saat kedua silinder bergerak dengan beda fase 90º daya yang dihasilkan lebih kecil namun stabil dan kontinu. Pada model setengah kendaraan dengan eksitasi sinusoidal yang sama pada roda kiri dan kanan,

Low efficiency of vehicle fuel utilization encourage the development of research in the field of energy harvesting. This research focused on designing a new type of Regenerative shock Absorber (RSA) called Hydro-Magnet-Electric Regenerative Shock Absorber (HMERSA) with dual input-single output,where the fluid flows from two HMERSA will be combined to move one hydraulics motor which coupled with generator. HMERSA Dual input-single output system will be applied on rear part of vehicle, where the vehicle was modelled as half car system. The input used in this research are sinusoidal and step input. The delay effect of one cylinder will be analyzed by varying the phase difference between two cylinder in the sinusoidal input. The simulation result indicated that highest damping force occurred when two hydraulics cylinder moving with 0 º phase difference. In 90º phase difference the power produced was smaller but stable and continuous. In half car model with identical excitation between left and right wheel, the power produced was increasing along with the rise of vehicle speed, highest power produced was 171 wat at 80 km/h velocity. In 90º phase difference between right and left wheel input highest power produced was 120 W at 80 km/h velocity
