Test contaminans of heavy metal Lead (Pb) have been done to the caisin plant in crowded location (Pratin, Karang Reja, Purbalingga) and quiet location (Gombong, Belik, Pemalang). Analysis done with dry destruction method used Atomic Absorption Spektrofotometry (AAS) instrument at wave length 283,3 nm.
From result analysis of caisin plant gets contaminant Lead (Pb) in crowded location 4,88 ppm and quiet location 4,79 ppm. The level is over the number which has been determined by BPOM that is 2 ppm. The result of validation method analysis performed on the test that the linearity obtained for (r) 0,9952, with value Standar Deviation (SD) and Relative Standart Deviation (RSD) in presision test are 2,93x10-4 and 2,74%. And to test limit of detection (LCD) and limit of quantitation (LOQ) with value 0,33 ppm and 1,11 ppm.
