The incapacity of the Indonesian National Police to find out all information about corruption in certain areas and the absence of regulations and laws about the use of informants in handling corruption need to be solved immediately to make sure the handling of corruption cases work effectively. Therefore, this research attempted to analyze the informant management carried out by the Lebak Corruption Unit and the related factors to the informant management conducted. This study applied qualitative research design by interviewing Lebak Corruption Unit officers and their informants. This research found that the informant management system carried out by Lebak Corruption Unit is divided into 4 stages, namely the recruitment, controlling, utilization, and the dis mission of the informant. In recruitment activities, the methods used by Lebak Corruption Unit include (1) persuasive methods; (2) the “paid” method; (3) the reciprocal method; and (4) coercion method. Meanwhile, based on Lawrence’s Legal System Theory, the related factors that influence informant management is the legal structure between the Indonesian National Police and the community, the absence of legal substance related to information management, and the culture of the community that is still ‘afraid’ of the police. These factors can be both reinforcing and weakening informants’ management efforts in certain sections.
