UGM Students Unveil Electric Motorcycle with 57% Domestic Content

Januari 11, 2024

The Gasbadra team at UGM has spearheaded research and development in Indonesia, focusing on creating electric motorcycles with an impressive 57.42% domestic component level (TKDN).

Dhamar Gumilang Panggayuh, the Gasbadra’s engineer, proudly shared the team’s achievement during a press discussion at the UGM Faculty of Mathematics and Natural Sciences on Thursday (Jan. 4).

“Our electric motor boasts a TKDN of 57.42%, surpassing the government’s target of 50% TKDN,” he declared.

The evolution of the electric motor has been ongoing since 2022, with the team continuously advancing various components under the guidance of the UGM Computer Science and Electronics Department lecturers. The project also receives support from PLN.

The Gasbadra team, led by Wisnu Aryo Jatmiko, has members Gilang Rizky Yunanto, Ferdian Arvin Nayandra, Alfahri Rifki Fahrezi, Heva Adlli Wijaya, Stefano Aldo Budi Satria, Rayhan Tegar Pamungkas, Muhammad Fakhri Ajrillah, Yuta Ilham Nugroho, Aulia Malik, Dhamar Gumilang Panggayuh, dan Faiz Yuda Anggoro–all are Electronics and Instrumentation students.

They diligently worked on crafting electric motorcycles to combat exhaust emissions from conventional fuel-based vehicles.

The team has delved into multifaceted research encompassing the frame, body, powertrain, and electric vehicle electronics, including the battery pack, power distribution, and BLDC controller.

“In our battery pack, we’ve incorporated a battery management system equipped with over-current, over-voltage, and short-circuit protection features to ensure battery safety,” explained Panggayuh.

Beyond safety, the Gasbadra team has prioritized efficiency and smooth starts for their electric motor. The team’s initiative aligns seamlessly with Sustainable Development Goal 7, which aims to achieve clean and affordable energy.

“In terms of electrical efficiency, our developed motor excels,” remarked Panggayuh.

Yuta Ilham Nugroho, another team member, highlighted that their electric motor’s range is comparable to other models on the market. However, it outshines competitors in producing a more powerful maximum output.

The team’s mid-drive DC brushless electric motor operates at 72V with a maximum current of 40A, delivering an impressive torque of 45Nm at 3000rpm and reaching speeds of 65-70 km/h with a max rpm of 4800.

The Gasbadra team has introduced two driving modes: eco mode and sport mode. In eco mode, the motor can cover an estimated 40 km on a single charge, emphasizing battery life.

On the other hand, sport mode prioritizes swift acceleration for a faster reach to the maximum speed. The estimated coverage in sport mode is up to 30 km.

“The fundamental difference in each mode lies in the acceleration curve. Sport mode reaches the maximum speed faster, while eco mode prioritizes battery life, offering smoother initial acceleration ideal for urban areas with flat terrain,” explained Nugroho.

The team has implemented a more responsive regenerative braking system in eco mode. When the throttle is released, regen brake activation produces reverse current, recharging the battery. The battery specifications include 84V 20Ah, requiring six to seven hours for a full charge.

“This electric motorcycle features a robust scrambler design, exuding a masculine aura tailored for terrain exploration. With a dual-purpose capability for road and off-road use,” he concluded.
