Abstract
This research is a development of previous research entitled "Designing Regenerative Shock Absorber as a Vibration Energy Harvesting Tool on Vehicles" in the PUPT scheme funded by PNBP UNP 2017. In this study optimization of design oriented to energy generation was carried out while also paying attention to aspects driving comfort that might change due to the installation of a harvesting energy mechanism. One aspect of the change occurred in the type of magnet used, namely a ring type magnet with a type of neodymium material.From the test results obtained by changing the value of the efficiency of the shock absorber after the ERSA mechanism is installed by 2%, this condition also has an impact on the dissimilarity of the attenuation value obtained by 2% for the front-rear (left) and (right) wheels. In terms of generation voltage obtained the maximum generation voltage obtained is 25,600 mV. Based on the data obtained, it needs further development ERSA, especially in the aspect of the electromagnetic mechanism to optimize the generation of electrical energy.

Summary
Perancangan Awal Berdasarkan hasil evaluasi penelitian sebelumnya dimana ditemui beberapa permasalahan antaranya: minimnya ruang gerak (dispalement) magnet, konstruksi magnet yang terlalu besar dan masih rendahnya tegangan yang dihasilkan. Maka pada penelitian ini dilakukan penyempurnaan baik dari segi desain manufaktur dan material yang digunakan. Sebelum masuk ke proses manufaktur, terlebih dahulu dilakukan pengujian panjang stroke (displacement) magnet saat proses pengujian. Ini dilakukan agar konstruksi magnet yang dibuat tidak melebihi stroke maksimal shock absorber. Berikut proses pengujian panjang stroke (displacement) shock absorber. Dari hasil pengujian diperoleh panjang stroke maksimal shock absorber adalah sebesar 15 cm. Proses Manufaktur Setelah konsep desain shock absorber diperoleh maka langkah selanjutnya adalah pemilihan material sesuai dengan kebutuhan dan konstruksi shock absorber. Pada mekanisme harvesting energy kali ini menggunakan menggunakan jenis ring magnet dengan bahan neodymium, berbeda dengan penelitian sebelumnya yang menggunakan ferrite magnet. Perubahan ini dilakukan dengan harapan diperoleh peningkatan voltase bangkitan yang lebih besar dari magnet sebelumnya.
