Generally, the aim of this research to know the comparison of caffeine drinks through the result of reaction time after consumption coffee, green tea, and energy drink by the same amount of caffeine. The way to gather the data is using purposive sampling, the population that chosen by the researcher is 10 respondents’ college students of Ilmu Keolahragaan batch 2016. For data analysis, using SPSS 21 program for windows and Statistical calculation that used is One-Way ANOVA continues with Post Hoc Tukey.
