Aceh is province of Indonesia located in the northern tip of Sumatra. It is rich of natural resources. Aceh was seriously affected and damaged by tsunami resulted from earthquake in India Ocean in December 2004. Mismanagement of natural resources in Aceh by the central government in Jakarta, which did not share equally the revenues from the natural resources, which has helped to create tension between elites in Aceh with the central government. Insulting the local tradition and religion by the central government is another fuel to generate quarrel. Given this bad situation, the Free Aceh Movement (GAM) was then established to challenge the GoI. Problems of human right abuses by Indonesian military during Aceh's DOM status have added more fuel to elicit armed conflict between GAM and the GoI. Conflict in Aceh cannot resolve only with using military forces by the central government. The conflict might be easy to be dealt with if the state can meet the need of all individuals and provide justice to them. Peace can be only be achieved if such a condition fulfilled. Since women play significant role in coloring the future of society in Aceh, they must be involved in the process of transforming conflict into peace. After the peace has been achieved, their participation is needed to maintain the peace in society. Gender discrimination, therefore, must not take place in Aceh anymore. Maintaining peace in Aceh post Helsinki MoU can be afforded by doing peace-building and peace-keeping activities. Successful peace-building in Aceh cannot be gained only from the outsiders' help, but it can be achieved by empowering the whole levels of indigenous population.
