Abstract

ABSTRAK Sepeda motor listrik merupakan mode transportasi yang saat ini sedang berkembang dikalangkan masyarakat. Terdapat komponen-komponen utama pada sepeda motor listrik untuk memberikan kenyamanan bagi pengendara, salah satunya adalah sistem suspensi. Dalam pemilihan sistem suspensi untuk kendaraan listrik E-Niaga perlu adanya perhitungan untuk mengetahui kemampuan pegas menahan beban yang diterima. Suspensi depa yang digunakan pada kendaraan E-Niaga memiliki nilai konstanta pegas 11,76 kg/mm dan kemampatan maksimal pegas saat terkompresi adalah 110 mm. Metode pengujian yang dilakukan suspensi ini adalah metode pendekatan one shot model dan variabel bebas pada penelitian ini adalah perbedaan medan jalan dan variasi kecepatan pengujian. Pengambilan data dilakukan dengan menggunakan sensor Arduino jarak ultrasonik tipe HCSR04 yang telah terprogram dan terpasang pada komponen suspensi depan kendaraan. Hasil dari pengujian yang dilakukan berupa data numerik yang kemudian diolah ke bentuk grafik menggunakan Microsoft Excel sehingga menunjukkan nilai defleksi yang alami suspensi. Defleksi yang dialami suspensi depan E-Niaga masih dalam batas ideal karena tidak mencapai Panjang kemampatan maksimal pegas yaitu 110 mm, dan defleksi terbesar dialami suspensi pada jalan berlubang dengan kecepatan 30 km/jam yaitu sebesar 87 mm, sehingga dapat di tarik kesimpulan suspensi yang digunakan E-Niaga masih aman karena nilai defleksi masih berada di bawah nilai kemampatan maksimal pegas. Kata Kunci: Suspensi teleskopik, Defleksi, Sensor jarak, Arduino, HCSR04. ABSTRACT Electric motorcycles are a mode of transportation that is currently developing in the community. There are main components on an electric motorcycle to provide comfort for the rider, one of which is the suspension system. In the selection of a suspension system for E-Commerce electric vehicles, it is necessary to have a calculation to find out the ability of the spring to withstand the received load. The depa suspension used in E-Niaga vehicles has a spring constant value of 11.76 kg/mm and the maximum compression of the spring when compressed is 110 mm. The test method carried out by this suspension is a one-shot model approach method and the free variables in this study are differences in road terrain and variations in test speeds. Data retrieval is carried out using an Ultrasonic distance Arduino sensor type HCSR04 that has been programmed and attached to the front suspension component of the vehicle. The results of the tests carried out are in the form of numerical data which is then processed into a graphic form using Microsoft Excel so as to show the natural deflection value of the suspension. The deflection experienced by the E-Niaga front suspension is still within the ideal limit because it does not reach the maximum spring compression length of 110 mm, and the largest deflection is experienced by the suspension on a hollow road with a speed of 30 km / h which is 87 mm, so it can be concluded that the suspension used by E-Niaga is still safe because the deflection value is still below the maximum spring compression value.
