Purpose: This study aims to analyze the implementation of the principle of equality through the 30% women’s quota policy in parliament and to examine its contribution to the realization of good governance in Indonesia, particularly in terms of the quality of representation and the substantive contribution of female legislators.

Research Methodology: This study uses a qualitative descriptive-analytical approach. Data were collected through in-depth interviews with stakeholders, participatory observation of legislative processes, and documentation studies of official policies and election reports. Data were analyzed thematically.

Results: The findings show that the quota policy has increased women’s participation at the nomination stage. However, a gap remains between administrative fulfillment and actual representation. Challenges include patriarchal culture, limited party support, high campaign costs, and non-strategic candidate placement. Despite this, female legislators contribute to gender-related policy issues.

Conclusions: The quota policy supports equality and inclusive governance but requires stronger institutional support and consistent implementation.

Limitations: This study is limited by its qualitative scope and reliance on selected stakeholders, which may not fully represent all regions or political contexts in Indonesia.

Contributions: This study contributes to public policy and governance by providing insights into improving gender quota effectiveness.
