<![CDATA[Introduction. The increasing number of visitors to the Jakarta Cikini Public Library requires professional and adaptive services, while the diverse educational backgrounds of service librarians raise questions about the implementation of competencies. This study analyzes service librarians’ competencies and the challenges they face based on the ALA Core Competencies. Research Methods. A qualitative approach was employed with four purposively selected informants representing different educational backgrounds. Data were collected through in-depth interviews, passive participant observation, and documentation. Data Analysis. Data were analyzed using the Miles and Huberman interactive model, including data reduction, data display, and conclusion drawing and verification, with thematic coding based on the nine dimensions of the ALA Core Competences to identify and categorize empirical findings. Results. Service librarians’ competencies develop through work experience and organizational culture, with a strong emphasis on professional values and ethics. The role of librarians has shifted into bridging information systems and user needs, supported by technology and collaborative work. Conclusion. Service librarians have demonstrated competencies aligned with several ALA standards despite varied educational backgrounds. However, the implementation is not yet optimal due to structural, operational, and communication constraints. The study highlights that diverse educational backgrounds create collaborative synergy that strengthens library services.]]>
