being analyzed with Kremtografi Lapis Tipis (KLT). The result of theanalysis
showed that all of the sample is negative. On the other hand, there is no
Rhodamin B on it. The indicated sample has the same Rf with Rhodamin B. It will
change it color into red as its response toward H2SO4 and HCl. The sample also
being compared with wantex. The result showed that the Rf samples had A3, A4,
A5, B4, B5,C1, C2, C3, C4 dan C5. Based on the result,the assumption of the
