Kecamatan Lembang in West Bandung Regency is prone to earthquakes due to the active Lembang Fault, capable of generating magnitudes of up to 6.5–7. Relawan Penanggulangan Bencana Lembang (RPBL), established in 2017 as a collaboration of five disaster-focused communities, works on disaster response and mitigation education, including partnering with Relawan Penanggulangan Bencana Lembang (RPBL). To maintain its relevance, a community must engage in capacity building, which involves identifying, mobilizing, and managing resources to address challenges and strengthen social, organizational, and material aspects. In disaster mitigation, this can be achieved through structural and non-structural approaches, such as disaster documentary films to raise awareness. Using a qualitative case study approach, this research gathered data through interviews and literature to explore how documentary filmmaking enhances community capacity and supports sustainable development. The findings show that documentaries effectively convey earthquake history, risks, and mitigation strategies in an accessible way, fostering broader collaboration and inspiring similar initiatives. Despite resource limitations, the project succeeded through partnerships with students and multimedia professionals, offering a scalable model for enhancing disaster resilience in vulnerable areas.
