Abstract

The purpose of this research is to create a microcontroller-based start reaction time measuring instrument using Research and Development (R&D) approach. This measuring instrument works when the START button is pushed, LCD becomes active, buzzer rings, and the LED indicator turns on. When athletes hear the sound from the buzzer, they release their feet from start block which causes push button on the right and left side of the start block sends voltage to ATMega micro controller and causes timer to stop and LED showing timer stops turn on. From this process, athlete reaction time can be seen on LCD. To restart the initial process, RESET push button can be pressed. The sample in this research was divided into two groups. The first group consisted of 30 students from sport science major, batch 2012 and the second group consisted of five sprinters from PPLP Atletik Jabar, using simple random sampling technique. The analysis showed that this measuring instrument had high validity score, which is 0.771 and a high reliability score, which is 0.834. The analysis also showed that the relationship between sprinter’s start reaction time and 30-meter distance was not significant.
