Development of Speed Measurement System for Pencak Silat Kick Based on Sensor Technology

This work develops the speed measurement system for pencak silat kick based on sensor technology. The system operates digitally, was made cheaply and is easy to carry for outdoor measurement. Measurement system can record sequentially speed data of reaction and action of a kick in milliseconds. Two sensors are applied in the system for detecting the movement of the kick consisting of Force sensor and Ultrasonic PING Sensor. The force sensor is used to detect the response kicker after receiving an instruction. Meanwhile, an Ultrasonic PING sensor is used to detect the kicker's foot after arriving at the target. The speed measurement system based on the experiment gives good result. The accuracy of the speed of action and the speed of reaction showed was 99.29 % and 99.33 %.
