Abstract
Seiring dengan perkembangan sepeda motor dalam masyarakat, spesifikasi kendaraan roda dua masih terbatas pada suspensi standar yang menggunakan sistem pasif. Dimana sistem suspensi ini belum mampu secara optimal mengatasi getaran yang timbul akibat berbagai kondisi jalan. Ketidakmampuan mengisolasi getaran mengakibatkan ketidaknyamanan bagi pengendara. Pada proyek akhir ini, dilakukan perancangan simulasi sistem suspensi semi aktif yang dapat menghasilkan respon keseluruhan dari model kendaraan roda dua yang sesuai dengan standar kenyamanan ISO 2631 dengan menggunakan kendali PID. Metode autotuning digunakan untuk menentukan nilai parameter pengendali PID. Hasil autotuning menghasilkan nilai Kp = 36836, Ki = 212093, dan Kd = 17587. Perancangan simulasi dilakukan dengan variasi kecepatan yang berbeda yaitu 15 km/jam, 30 km/jam, dan 45 km/jam. Terdapat tiga jenis lintasan pengganggu jalan yang digunakan, yaitu step, impulse, dan sinusoidal. Perancangan ini bertujuan untuk mendapatkan hasil respon percepatan dan simpangan yang dialami bodi kendaraan dari sistem suspensi semi aktif yang dibantu oleh gaya aktuator, dan membandingkannya dengan sistem suspensi pasif. Dari hasil simulasi yang dilakukan, sistem suspensi semi aktif yang dirancang dapat menghasilkan respon percepatan pada bodi kendaraan yang sesuai dengan ISO 2631. Seluruh parameter dari sistem suspensi semi aktif yang dirancang menghasilkan rentang nilai displacement 0.0005 – 0.006 m, nilai settling time selama 0.5 – 2s ,serta nilai a_{rms} sebesar 0.050 – 0.28 {m/s}^2,dimana nilai ini sudah sesuai dengan standar kenyamanan yang sudah ditetapkan ISO 2631 yaitu a_{rms}< 0.315 {m/s}^2.

Along with the development of motorbikes in society, the specifications of two-wheeled vehicles are still limited to standard suspensions that use passive systems. Where this suspension system has not been able to optimally overcome vibrations arising from various road conditions. The inability to isolate vibrations results in discomfort for the rider. In this final project, a semi-active suspension system simulation design is carried out that can produce an overall response from a two-wheeled vehicle model that complies with ISO 2631 comfort standards using PID control. The autotuning method is used to determine the value of the PID controller parameters. The autotuning results produce values of Kp = 36836, Ki = 212093, and Kd = 17587. The simulation design is carried out with different speed variations of 15 km/h, 30 km/h, and 45 km/h. There are three types of road disturbance trajectories used, namely step, impulse, and sinusoidal. This design aims to get the results of the acceleration and deviation response experienced by the vehicle body of the semi-active suspension system assisted by the actuator force, and compare it with the passive suspension system. From the simulation results, the designed semi-active suspension system can produce an acceleration response on the vehicle body in accordance with ISO 2631. All parameters of the designed semi-active suspension system produce a displacement value range of 0.0005 - 0.006 m, a settling time value of 0.5 - 2s, and a_{rms} value of 0.050 - 0.28 {m/s}^2., where this value is in accordance with the comfort standards set by ISO 2631, namely a_{rms} < 0.315 {m/s}^2.
