Abstract :
Chlorpyrifos pesticide is group of a organofosfat pesticide that used to exterminate some types of pest on the plant, excessive spraying and exposure of pesticide on a plant shall renounce residual pesticide on a plant. One of them that sprayed with chlorpyrifos pesticide is onion spring, The purpose of this research is to know how many chlorpyrifos pesticide residual levels on onion spring. The method to determinate pesticide residual levels chlorpyrifos is using UV-VIS spectrofotometry, and obtained 694 nm wavelength, with 15 minute operating time. The fresh onion spring extracted with aceton. The result of extraction is used to quantitative test. The average result level chlorpyrifos on onion spring is 0,1855 ± 0,008694 mg/kg with CV% is 4,6244%.
