Community health centers (Puskesmas), as primary health facilities, play a strategic role in providing quality, affordable, and easily accessible health services to the public. The transformation of primary health services through the integrated primary service (ILP) approach at the Karangan Community Health Center, East Kutai Regency, aims to provide integrated services based on the life cycle, from infants to the elderly, by utilizing competent human resources and supporting information technology. This study uses qualitative methods, including observation and interviews, to describe the implementation of ILP-based health services and the factors that support and inhibit it. Based on the study's results, the implementation of ILP at the Karangan Community Health Center has run smoothly, with integrated services and strong cross-cluster coordination. Internal supporting factors include competent human resources, adequate facilities, and management support; external supporting factors include policy support, support from the Health Office, and support from related cross-sectoral partners. However, a limited number of health workers, differences in staff understanding, and technical constraints in the information system remain internal inhibiting factors.
