The rise of motor robber that have lately made the concern of Linus Nara Pradhana students from SMAN 16 Surabaya to create something that could be useful for the safety of motorists from the threat of robber, the anti-robber helmet, this helmet is equipped with a tool capable of turning off the engine from a motorcycle we if our motor is taken by the thieves, so automatic offender will not be able to bring our motorcycle fuzzy.
This discovery creates a security device based on a remote control system with electromagnetic waves that are not affected by obstruction, so the system is suitable for use on motorcycles that will be carried away or hidden thieves. From the results of this discovery then he became one of the winners in the national competition Inventor award held by the Indonesian science institutions in Jakarta in 2015. In addition, this discovery is the most get the attention of visitors in the exhibition event in the series of the competition
In this invention he creates a series of transceivers and receivers, where the transceiver is placed inside the helmet shell in order to keep the helmet safe from water and not harm the wearer. While the receiver is placed inside the motorcycle. If one of the transceiver switches is in press (eg switch1) then the data informs the microcontroller IC to proceed to the transceiver circuit. The signal that has been sent is received by the RF circuit (Radio Frequency) on the receiver circuit, then it will be in though by the microcontroller IC to activate the relay (eg relay 1). The relay is connected to the electrical part (eg ECU) so that the motor is off, if the motor contact is forced the alarm will sound. So also for other scalars. With this discovery is expected that this hem in mass production and can be used for the general public, so free from motorbike robbery in the street
