Analisis Residu Pestisida pada Komoditi Jeruk Manis ( Citrus sinensis) dari Kecamatan Sidikalang Kabupaten Dairi dengan Menggunakan Alat Kromatografi Gas

Abstract

Analysis of pesticide residue levels in sweet orange (Citrus Sinensis) was carried out using a gas chromatography with the extraction method. The cut samples were dissolved in acetone, dichloromethane and petroleum ether, refined with ultraturax and left to stand until the filtrate and residue separated. The filtrate will be dried using a rotary evaporator and the result will be dissolved in isooctane and toluene ina ratio (90:10) and put into a test tube. Then determine the yield of the extract injected 1-2 μL in a gas chromatograph equipped with a specific detector for compounds containing elemental phosphorus (FPD) and (AFID). From the results of the analysis, it was found that the levels of pesticide residues in lime fruit with the standard active ingredients diazinon and fention were not detected while the standard active ingredient chlorpyrifos was detected at 0.165 mg/kg. This shows that the levels of pesticide residues in lime fruit do not exceed the maximum residue limit stipulated by the Regulation of the Minister of Agriculture of the Republic of Indonesia Number: 88/Permentan/PP.340/12/2011 concerning the maximum residue limit of pesticides on agricultural produce of lime fruit, namely 0.5 mg/kg and still fit for consumption by the public.
