This study examines the role of Posyandu Lansia (Elderly Integrated Service Post), a community health program, in supporting elderly well-being in Kelurahan Kricak, Yogyakarta. As older adults face loneliness and the risk of non-communicable diseases, Posyandu Lansia offers a space for social interaction, strengthening social bonds and resilience. Through a qualitative case study involving elderly participants and  Posyandu cadres, selected based on participation levels, the research explores how regular Posyandu activities impact participants' physical, social, and emotional health. Findings show that Posyandu activities mitigate loneliness, offering a reunion-like setting for shared memories and community connection. Elderly participants highly value these gatherings for fostering close, familial ties with cadres, who support them with enthusiasm and care. The program is seen as beneficial in preventing non-communicable diseases, such as hypertension, by enhancing social and emotional support, underscoring its importance for elderly health and community cohesion.
