Motorcycles are the biggest contributor to driving accidents in Indonesia. Some of the accidents that occurred were caused by the negligence of passengers who did not pay attention to the clothes worn when riding a motorcycle. Generally, this happens to women who wear long headscarves or skirts that are too deep so that the hijab or skirt gets into the fingers or chain of the motorcycle until it becomes entangled and causes a single accident or even a series of accidents. According to Ghani (2018) published by detikNews, such an incident occurred in one of the Bayongbong Districts, Garut, where a mother and her child fell from a motorcycle and were run over by an elf car, both of whom died instantly at the scene. The long robe worn by the mother was wrapped in a motorcycle chain. As a result they fell from the motorbike but from the same direction the elf drove and crushed the mother's body. Conditions like this must be handled by proper precautions so that there are no more single or consecutive accidents caused by the entanglement of the hijab or the skirt worn by the passenger. This prevention can be done through an innovation that was created under the name Smart Alert as an effort to prevent the passenger's skirt or hijab from being wrapped around a motorcycle chain or spokes. Smart Alert will display the distance from the detected skirt or hijab. When it detects an object to be entangled, Smart Alert will issue a signal in the form of a blinking LED at a distance of ≤15 cm and <10 cm. If the object is within a distance of ≤10 cm dan <5 cm, the LED will turn on and the buzzer will sound simultaneously. However, when an object is detected within a range of ≤5 cm the system of Smart Alert will count down for 3 seconds. If within that time period the object to be entangled is detected again, the Smart Alert system will automatically disconnect the positive connection between the battery on the motorcycle and the coil so that the engine turns off and the motor stops automatically. Smart Alert as a smart tool that can anticipate the winding of the skirt when riding is placed at the bottom near the motorcycle chain. Smart Alert is expected to take on the role of being one of the technological innovations in the automotive industry that prioritizes passenger safety so that driving accidents can be avoided and minimized.
