Furthermore, this descriptive qualitative research used non randomsampling as its technique. The sample is taken from pentol seller, mie ayam seller and baksoseller. The samples are 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 onit. The indicated sample has the same Rf with Rhodamin B. It will change it color into red as itsresponse toward H2SO4 and HCl. The sample also being compared with wantex. The resultshowed that the Rf samples had A3, A4, A5, B4, B5,C1, C2, C3, C4 dan C5. Based on the result,the assumption of the samples is that the samples have wantex material on it
