Halim Perdanakusuma Urban Village is an urban area characterized by high flood vulnerability, while residents' understanding of disaster-related law and behavioral preparedness (human factors) remains limited. This community service program was implemented by an interdisciplinary team from Universitas Dirgantara Marsekal Suryadarma (UNSURYA), integrating the fields of Legal Studies and Aviation Human Factors, with the aim of enhancing disaster law literacy and adapting aviation human factor principles—particularly those emphasizing situational awareness, effective communication, teamwork, procedural discipline, and stress management—into community-based flood disaster management. The program was carried out through five stages: socialization, training, implementation of practical tools, mentoring and evaluation, and sustainability planning, culminating in legal counseling, human factor training, and a flood evacuation simulation conducted on 12 June 2026, attended by 20 core participants comprising residents and RT/RW (neighborhood/community) cadres. Evaluation was conducted using a pretest-posttest instrument, which showed an increase in the mean knowledge score from 5.1 to 9.3. The resulting outputs included the Halim Flood Law and Human Factor Module 2026, a Community-Based Flood Management Standard Operating Procedure (SOP), and a Flood Preparedness Checklist, all of which have been distributed to the Kelurahan (urban village office) and RT/RW units. The integration of disaster law and aviation human factors proved effective in improving residents' knowledge and preparedness.
