Abstract

Currently, the production of consumable- rise relies on rice fields especially technical irrigated rice fields. In increasing rice production, the use of insecticides become the main option to control the pest attacks.This condition generates the environmental pollution of insecticide residues on the field- soil. The most widely used- pesticides by the lowland rice farmers are insecticides or poisons to control plant pests.The active ingredients contained in insecticides are methomyl, fipronil, buprofezin, and chlorantanipol and others. Each active ingredients have the percentages of 19.20%, 16.87%, 13.56%, 13.32%, and <10%, respectively. This study aims to detect insecticide residues in the soil generated by the insecticides uses.This research was conducted at the Musi Rawas rice field center which uses insecticides as the pest control. This research was conducted in March 2018 using survey method by taking soil samples on rice fields. Residual analysis was analyzed using Gas Chromatography (GC) in the Environmental Laboratory of the Indonesian Center for Biodiversity and Biotechnology Bogor (ICBB). Laboratory test results detected 0.04 ppm of methomyl as the highest residual content in the sample.Therefore, the result has exceeded the quality standard which is 0.02 ppm. Moreover, the soil needs the further remediation to reduce contaminated- pesticides.
