ABSTRACT: <br /> <br /> <br /> <br /> <br /> Organophosphate (OP) compounds are extensively used throughout the world in various activities especially for agricultural control of wide range of insect species. This pesticide can be dangerous for areas or organism non-targets as a result of runoff from site of application. These facts highlight the potential problems in conserving biodiversity in agricultural areas where pesticides are used. Therefore, in this research samples collected from two different sources, organic farming soil and inorganic farming soil, to measure the residue of organophosphate insecticides, Total Plate Count of bacteria and also identification of isolated soil dominant bacteria from those sources. The differences between these soils are the insecticides application. In organic soil natural insecticide is used while in non-organic soil organophosphate insecticides are used. Bio-indicator are used to monitor the health of an environment or ecosystem. Total amount of soil bacterial colony is used as bio-indicator to see the effect of insecticides in farmland. The strains were identified by the biochemical methods and the residue is measured by Shaker method (Komisi Pestisida 1997). This research obtained that total bacteria in residual insecticide contaminated agriculture soil has less tendency in amount compared with organic agriculture soil. However, the difference is not significant. Besides, bacteria that can degrade organophosphate compound were founded on that agriculture area.
