![]() Thus, surfactants act as a bridge and increase the effectiveness of pesticide washing using water. During the washing process using water, the hydrophilic part will interact with water while the lipophilic part will interact with lipophilic contaminants including pesticides. The pesticide of chlorpyrifos, was highly lipophilic it will not dissolve easily in water, and requiring surfactants for the washing process. The Oxalis dehradunensis Raizada leaves contain flavonoids and saponins has supported the washing process of pesticide application among farmers. However, several studies have examined the herbal contents of handwashing soap. It is widely used as an antibacterial material. Concerning several studies, hand soap gel use is adapted by technological developments and modified in the form of a hand sanitizer. Therefore, hand washing media, namely hand soap gel, is more intended for anti-microbial properties. ![]() It needs to implement a health and safety program to protect against contamination caused by pesticide spilt and dispersed. The habit of washing hands after spraying can significantly reduce the potential for toxicity caused by pesticide exposure from leaking containers and spills. It concluded the Oxalis dehradunensis Raizada leaves are effective to clean the pesticide residues. The ability of hand soap gel with Oxalis dehradunensis Raizada concentration of 5% and 7% in binding residue compounds of chlorpyrifos pesticides was considered good. The results found that Oxalis dehradunensis Raizada was formulated into hand soap gel could remove chlorpyrifos pesticide residue from hand wash of the farmers. The data were analyzed in quantitative and gas chromatography to find the ability of the extract to remove chlorpyrifos pesticide residues, in the farmer's hand wash water as a qualitative test. The water of the farmer's hand wash was check-in the laboratory for screened phytochemicals. All farmers used a pesticide with chlorpyrifos content and wash their hands by using handsoap gel extract ethanol Oxalis dehradunensis Raizada formula. The extract was gained from the leaves powder was repeatedly extracted by maceration. ![]() ![]() The material used fresh Oxalis dehradunensis Raizada leaves, collected from farmer's fields. It is a pre and post experiment that was tried by 30 farmers from Karo district, Indonesia. The experimental research was conducted to explore the potential of the leaves as an alternative material for pesticide cleaner. This study was aimed to determine the effective formula of Oxalis dehradunensis Raizada leaves extract as hand soap gel preparation to remove pesticide residues. ![]() The Karo's farmers use the plant as a substitute for water and soap called acem acem ( Oxalis dehradunensis Raizada) leaves to clean the direct pesticide exposure at their skin. ![]()
