Rancangan sistem palang pintu otomatis pada jalur bus rapid transit (BRT) berbasis Arduino

Abstract

Transjakarta bus was officially operated in 2004 and until now there are thirteen corridors that operate. The purpose of this bus operation is to solve the congestion problem in DKI Jakarta. Its separate lanes with the public lanes makes Transjakarta buses run normally even though the public lane next to it is jammed. As time passes, new problems arise in this system, such as burned buses to other vehicles which go on the bus lane illegally paths. Due to many illegal passersby from the society, there are also many accidents in the lane. This study aims to design an automatic doorstop system on Transjakarta bus lanes, so that the illegal passersby can be minimized in order to eliminated the accident figure. This system is a miniature with a scale of 1:25 and is positioned on the Transjakarta bus lanes that intersect with other vehicles turning U-turn lane. The miniature is using Arduino Leonardo as a microprocessor and a servo motor as a crossing barrier that moves 90 degrees. Reed switch sensors are used as the bus detectors that are placed in the beginning and end of the path of the system. Based on the research that has been done, we obtained a result that the system is running well and that the reed switch sensors can be applied as a bus detector. The important elements in this system are, when the bus passes through the sensor, its speed has to be adjusted so that the sensor can detect the bus when the bus passes it.
