This research aims to determine the refraction index charge in liquid by means of Paul Gluck and compare the refraction index to standard values by means of experimental design experimental series, based on the principle of Paul Gluck. "N =" ("D", "x 2," ⁄"")/("D", "-2" ⁄"x-d") and compared with standard values found that liquid refraction index value of 5 kinds: water syrup, alcohol, ethyl alcohol and Methyl salicylate klisoerin. There is 1 refraction index.3325, 1.4302, 1.3187, 1.3472 and 1.4387, respectively, this is a staggering percentage of 0.04, 0.72, 0.79, and 1.06, respectively, which is 2.13 per cent maximum tolerance of 3
