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.
