Yellow and red watermelon has a high water, potassium and sodium content that can increase diuresis. However, research differences in yellow watermelon diuresis and red watermelon in adults have not been studied. The purpose of this study was to know the difference of the yellow watermelon diuresis with red watermelon.
This research is an experimental research with crossover design. The material used 187 g watermelon juiced with 250 ml average juice. This study used a redesign with yellow watermelon juice treatment (250 ml), and red watermelon juice (250 ml). The sample fasted for 10 hours before treatment, then total urine volume was measured at 1, 2, 2.5 hours.
The urine volume data was tested for normality with Shapiro Wilk showing abnormal data distribution, followed by Wilcoxon test. The average urine volume after 2.5 hours of red watermelon delivery was 81.83 +34.75 ml and after administration of the yellow watermelon was 105.20 + 50.04 ml.
Wilcoxon test results obtained p <0.002 which means there are significant differences. The conclusion of this study is the total volume of urine yellow watermelon is greater than the red watermelon in adults. Keywords: watermelon, urine, potassium, sodium.
