This study explores the bargaining position of Acehnese women in public policy forums through their participation in Musrena (Women’s Development Planning Forum) and Musrenbang (General Development Planning Forum) in Banda Aceh, Indonesia. Using a contemporary feminist ethnographic approach, the research documents how the Balee Inong community—a grassroots women’s network—engages with the state planning apparatus to influence gender-responsive budgeting and development agendas. Data were collected through field observations, in-depth interviews, and documentation studies involving key stakeholders at village and city levels. Findings indicate that Musrena serves as an effective platform for amplifying women’s voices in formal planning processes, offering both structural and symbolic space for women's political engagement. The institutionalization of Musrena through local regulations has significantly enhanced women's visibility and agency, particularly in negotiating budget allocations and shaping gender-equitable policies. Furthermore, the study reveals how historical narratives, religious values, and local wisdom interact with state mechanisms to produce a uniquely Acehnese model of participatory development. The research highlights the potential of localized feminist strategies in transforming hierarchical planning systems into more inclusive, bottom-up processes. It contributes to global discourses on gender budgeting, feminist governance, and community-based planning innovations.
