Development of Leg Power, Force and Reaction Testing Device Based on The Affordable Platform with Android in Badminton

Abstract

The purpose of this study is the development of leg power, reaction time, and force device based on affordable platform with android in badminton. The method used the Research & Development (R&D) approach. 30 samples were involved in testing the prototype device instrument. The materials used were Loadcells TAL220 sensor, Arduino Nano Microcontroler and Bluetooth HC-05. The results showed that the correlation coefficient values for the measurement of the leg power, reaction and force variables each had values r = 0.904, r = 0.891 and r = 0.687, while the reliability were leg power r = 0.832, reaction r = 0.841, and force r = 0.972 using a significance level of 0.05.The conclusion from these data shows that the prototype of this device instrument has a high value of validity and reliability after compared with standard commercial tool so that this prototype is very feasible to be used especially in badminton
