Several studies revealed strategic role of women non-governmental organizations (women’s NGOs) in Indonesia, from the New Order (Orde Baru) to the reform era (era reformasi). However, there are not studies have assessed capacity of women’s NGOs in post-reformasi Indonesia, especially to supporting women’s political participation. The existing framework such as gender mainstreaming (Pengarusutamaan Gender, PUG) that was introduced in 2000 does not sufficient to assess capacity of Indonesian women’s NGOs. Therefore, this study fills the gap by utilizing a bottom-up approach and feminist research methodology to hearing voices and collecting thoughts of various women’s NGOs activists in Jakarta, West Java, Yogyakarta, West Sumatra, North Sumatra, and East Nusa Tenggara. Data were collected by means of 21 Focus Group Discussions from 2020 to 2021. This paper develops a genuine and locally-based framework called MSSG (Masyarakat Sipil Setara Gender) or the Gender Equal Civil Society, as framework for mapping the capacity of women’s NGOs, and their actions in promoting gender equality to supporting women's political participation. The MSSG consists of two dimensions: gender mainstreaming and women's empowerment, each of which consists of five elements namely (i) representation (descriptive & substantive), (ii) autonomy, (iii) consolidation, (iv) local context & intersectionality, and (v) social bases. Locating into the classical study of women's representation by Norris and Lovenduski (1995, 1997) which introduces the “supply and demand” model based on the western democracy experience. The MSSG contributes to the supply-side, based on the experiences and voices of women's NGOs of the Global South.
