Pemanfaatan Polisi Tidur pada Palang Pintu Otomatis sebagai Penggerak Mula Generator dan Pemanen Energi Listrik

Abstract

It is known that daily human activities cannot be separated from the need to use motorized vehicles. On the streets, speed bumps are one of the important equipment for traffic infrastructure. Of the many vehicles that pass through speed bumps, unconsciously there is wasted energy which can be converted into electrical energy. In this study, a speed bump power plant will be designed to become a prototype for generating electrical energy that utilizes kinetic energy from the activities of motorists, and is applied to an automatic barrier gate to assist security conditions in an area that is need. The electrical power harvested from the speed bumps will be used as a power source to operate the automatic doorstops and alternative power sources. The results of the operation of the prototype of the speed bump power plant that has been designed, under the condition of a vehicle mass passing 270 KG at a speed of 10 km/hour, obtained rotational speed data of 207 RPM, and generated power reaching 49.7 Watts. From this research it can be concluded that the heavier the mass of the passing vehicle, the greater the harvested electric power.
