Population ageing has become a major social welfare issue requiring responsive local government intervention, particularly for neglected elderly people. However, research on the institutional role of local Social Affairs Offices in improving elderly welfare through shelter home programs remains limited, especially in Solok City. This study aims to analyze the role of the Solok City Social Affairs Office in improving elderly social welfare through the Istana Lansia Serambi Madinah Shelter Home Program and to identify obstacles in its implementation. A qualitative approach with a descriptive case study design was employed, involving eight informants selected through purposive sampling. Data were collected through observation, in-depth interviews, and documentation, then analyzed through data reduction, data display, and conclusion drawing. The findings show that the Social Affairs Office performs three main roles: regulator, facilitator, and change agent. These roles are reflected in policy implementation, provision of basic services, temporary accommodation, health assistance, social and spiritual guidance, psychosocial support, and encouragement of elderly social participation. However, program implementation remains constrained by limited budget, inadequate facilities, insufficient professional assistants, and the absence of sustainable empowerment programs. The study concludes that strengthening institutional capacity is essential to improve elderly welfare services in Solok City. These findings contribute to social welfare studies by demonstrating the strategic role of local government institutions in elderly social protection and provide practical implications for improving shelter-based welfare services through stronger budgeting, facility development, professional staffing, and sustainable empowerment programs.
