Abstract

Pesticides are one of the substances that are widely used to protect plants from pests and plant diseases, and their use must be controlled for the public health. Currently, the pesticide contamination is determined by chromatographic, but this technique is destructive and not easy to implement. Therefore, this research is proposed to overcome these problems. Raman scattering technique as a non-destructive testing technique and easy to implement is used in this research. This technique utilizes Raman scattering resulting from laser excitation in a sample. Pesticide detection was carried out by observing the difference in Raman shift wavelength between samples containing pesticides and samples that did not contain pesticides. The experiments were done on guava peels with coated pesticide delthametrin 25 g/l. By excitation with laser wavelengths 532 nm and 785 nm, the differences in Raman shifts at wavelengths 1,225 nm and 1,480 for samples coated pesticide, and Raman shifts at wavelengths 1,008 nm and 1,480 nm for samples which is treated are obtained, respectively. From this research, it can be concluded that Raman scattering technique can be used as non-destructive and easy technique for detection pesticide contamination.
