HOMOGENITAS TARGET DALAM MATRIK PADA ANALISIS RESIDU PESTISIDA KARBAMAT DALAM TOMAT
Abstract: Optimum condition of
carbamate are carbofurane and carbaryl recidues pesticide analysis by height
performance liquid crhomatography (HPLC) has been done. The optimum condition
are isocratic mobile please on acetonitrile/H20 :45/55 (v/v) and wave lenght of
ultra violet (UV) detector has optimum absorbance at 275 nm. Performance of
HPLC verification has minimum detection are 60 pbb for carbofurane and 40 ppb
for carbaryl. Linierity and work range are 0.06 to 0.15 ppb for carbofurane
with r2 value of 0.9702 and 0.04 to 0.15 ppb for carbaryl with r2 value of
0.09874. Precision of HPLC was showed by relative standard deviation (RSD), for
carbofurane are 0.30 % of retention time (Rt) and 7.2 % of area. Whereas for
carbaryl, the RSD are 0.20 % for Rt and 4.63 % for area. Homogeneity of targets
in tomato matric as well as carbaofurane and carbaryl are homogen by analysis
of varians (ONOVA) method which. is showed by F-value < F-critis. Homogeneity anlysis by National
Acreditation of Comeetee (KAN) method also homogen with criteria I.
