This study aims to analyze how the local adaptation of Gus Dur's values shapes the humanitarian social movement of Gusdurian Mojokutho 87 Pare through community-based social practices. Existing studies on Gusdurian have primarily emphasized pluralism, movement framing, resource mobilization, and humanitarian activism, while the mechanisms through which Gus Dur's values are localized and transformed into collective identity, solidarity, symbolic action, and movement sustainability at the community level remain underexplored. This study employed a qualitative approach using a single case study design. Data were collected through in-depth interviews, observations, and documentation involving six purposively selected informants consisting of a community coordinator, active volunteers, beneficiaries, community leaders, and institutional partners. The findings show that Gus Dur's values undergo a process of norm localization, whereby community actors reinterpret and adapt them into locally relevant humanitarian practices, including child mentoring, elderly care, interfaith engagement, cultural activities, and disaster response. This process generates collective identity through shared participation and kinship, strengthens solidarity through moral commitment, flexible volunteerism, and collaborative networks, and produces symbolic action through cultural performances, interfaith encounters, and everyday humanitarian practices. Theoretically, this study extends Norm Localization Theory by demonstrating that local adaptation of religious values also generates mechanisms of collective identity, solidarity, symbolic action, and movement sustainability. It also enriches New Social Movement Theory by showing that the production of meaning in faith-based social movements is reproduced not only through cultural symbols but also through sustained humanitarian practices embedded in everyday community life.
