Pesticides are potential chemicals widely used in the agricultural sector to tackle pests and plant diseases. However, pesticides, for instance, profenofos, can pose a risk of poisoning to farmers. It is necessary to prevent profenofos exposure through early detection using rhodamine 6G. The detection of the reaction between profenofos and rhodamine 6G requires an optimum medium. This study aimed to test the optimum medium to facilitate the reaction of profenofos and rhodamine 6G. Five media variations were utilized, including paper, hand plaster, panty liner, diaper, and hydrogel. The detection was performed by spraying profenofos at various concentrations, ranging from 100 to 400 ppm on respective media. The study adopted a rhodamine 6G and profenofos reaction sensitivity test on those five media. It applied both qualitative and quantitative analyses. The qualitative analysis aimed to observe various concentrations of profenofos based on the changes of colors on respective media, in which (+) marked the medium sensitivity while (-) indicated insensitivity. The quantitative analysis utilized a ultraviolet-visible spectrophotometry to measure the changes of colors based on the reaction of profenofos with rhodamine 6 G. Both qualitative and quantitative tests showed no changes of colors on paper, hand plaster, panty liner, and diaper. In contrast, hydrogel reflected the changes of colors based on the increasing concentrations of profenofos. The research recommends hydrogel as an optimum medium for the early detection of profenofos pesticide exposure.
