ELARBI, a physical condition detection device that can make electric-powered manual bicycles, an innovation of UNESA team
Unesa.ac.id, SURABAYA - To minimize unwanted things such as fainting and accidents while cycling, a team of lecturers from the Faculty of Engineering (FT), Surabaya State University (UNESA) created an innovation called ELARBI. This tool is specifically designed to detect the physical condition of cyclists.
This innovation originated from Wahyu Dwi Kurniawan, S.Pd., M.Pd., and his fellow lecturers who saw many people following the trend of cycling, especially during the pandemic. These people tend to force themselves to cycle with heavy and long tracks.
As a result, many are too exhausted, faint and some have accidents. “In fact, cycling is for health,” said the chief initiator of ELARBI.
The tool, said Wahyu, has a special sensor that is worn on the hand. Its function is to detect the heart rate and oxygen saturation of cyclists. When someone exercises their oxygen saturation must decrease and their heart rate will increase.
The device will give a warning if a person's oxygen saturation is below 95 or if the heart rate increases by more than 80% before cycling.
“So if ELARBI has detected someone is tired, a warning will appear in the form of a sound and the words forbidden to ride will appear on a small screen on the bicycle steering wheel,” he explained.
Not only that, it is also equipped with electrical components that cyclists can use when they feel tired or when going uphill. In other words, it can turn an ordinary bicycle into an electric bicycle. The use of electric propulsion has six options to choose from. Starting from the full pedaling option to the full electric push option.
He revealed that so far electric bicycle users only rely on full electric power for their use, so this electric bicycle innovation makes users also required to exercise with the right intensity.
“This tool is equipped with a battery. Charging takes about 2 hours which can be used for a distance of 38 km at the maximum option. It can also increase according to the cyclist's options,” he added.
ELARBI, which can be installed on various types of bicycles, also involves other lecturers such as Prof. Dr. I Gusti Putu Asto Buditjahjanto, S.T., M.T., Agung Prijo Budijono, S.T., M.T., Awang Firmansyah, S.Or., M.Kes., and Susi Tri Umaroh, S.Pd., M.Pd. In its development, the lecturer team collaborated with CV Cahaya Berkah Gusti in the Kedaireka program scheme. [UNESA HUMAS]
