The increase in cases of human trafficking among Indonesian citizens has encouraged cooperation between the police of ASEAN member countries, especially the Indonesian National Police in dealing with this problem. This research aims to determine the efforts of the INP and the police who are members of the ASEANAPOL (ASEAN Nations Police) organization in carrying out cooperation to reduce and minimize cases of human trafficking in Southeast Asia. The method used in this research is a descriptive method supported by various reference sources through literature studies and interviews with related parties. The results of this research indicate that coordination/communication is the main key to the cooperation carried out by the ASEAN police, whether through international meetings, deployment of INP personnel abroad, or joint training of personnel. Apart from that, this research also shows that there has been a reduction in the number of cases through the coordination system (directly and indirectly). From this coordination, a cooperation model was formed, namely the Joint Coordination System (JCS) to analyze the cooperation between the INP and the police in Southeast Asia in repatriating Indonesian citizens who were victims of human trafficking so they could return to Indonesia. Therefore, having coordination between the parties involved really helps the success and effectiveness of the collaboration carried out
