The relationship between women and terrorism has undergone a significant shift in perspective. Initially, women were associated with being victims of terrorism, but now they play a role in various activities within terrorism. As a result, the burden of rehabilitating female terrorist inmates is disproportionately placed on correctional institutions. Therefore, National Counterterrorism Agency recognizes the importance of implementing mitigation, prevention, and deradicalization programs to have a more effective impact. This study uses qualitative research methods, including interviews and document analysis, and data validation through triangulation. The aim of this research is to examine the implementation, inhibiting and supporting factors, as well as the cooperation strategy between National Counterterrorism Agency and the Ministry of Defense in countering female terrorism in Indonesia. The results of this research first show the implementation of national defense in combating female terrorism in Indonesia through the implementation of the National Defense Awareness Program and increasing cooperation with local governments, TNI, Polri, and other parties. Second, regulatory obstacles are the inhibiting factor, while the supporting factor is the collaboration and coordination with relevant institutions to facilitate the handling of female terrorism in Indonesia. Third, the cooperation strategy of deradicalization between National Counterterrorism Agency and the Ministry of Defense prepares and anticipates potential terrorist threats that can endanger national security, public safety, state sovereignty, and the integrity of all regions of Indonesia..
