Abstract :
Pesticides are often used in agriculture to control plant pests. One of the
pesticides that is often used is chlorpyrifos. However, the use of pesticides has
the risk of triggering theemergence of pesticide residues in agricultural products,
which if consumed can be bad for health. This research aims to determine the
presence or absence of chlorpyrifos pesticide residues and to find out the levels
in purple eggplant (Solanum melongena L.) studied. Analyzes were performed
using the HPLC method with the C18 column stationary phase, the mobile phase
of acetonitrile : aquabidest (50:50) with isocratic elution, flow velocity of 0,70 mL
/ min and detection wavelength at 291,0 nm. The results showed that purple
eggplant (Solanum melongena L.) tested positive containing chlorpyrifos at
retention time of 3,236-3,252 minutes with a relative time of 0,996 to standard
chlorpyrifos at a retention time of 3,258 minutes. Chlorpyrifos residue levels
obtained in purple eggplant (Solanum melongena L.) of 148,44±8,71 mg/kg with a
KV value of 5,47%. The maximum limit of chlorpyrifos residues in eggplant is
0,2 mg/kg.
