<![CDATA[The study was motivated by the low level of organizational support and recognition perceived by nurses, which affected their job satisfaction and organizational commitment. This study aims to examine the effect of perceived organizational support on organizational commitment with job satisfaction as a mediating variable among nurses. This research used an explanatory quantitative approach with purposive sampling techniques based on the criteria of nurses with PNS, PPPK, and BLUD status who had worked for more than one year. The subjects consisted of 157 nurses at Dr. Ferdinand Lumban Tobing General Hospital, Sibolga, North Sumatra. Data were collected using the Perceived Organizational Support Scale, Organizational Commitment Questionnaire (OCQ), and Job Satisfaction Survey (JSS). Data analysis was conducted using Structural Equation Modeling (SEM) based on Partial Least Squares (PLS) through SmartPLS 4. The results showed that perceived organizational support had a positive and significant effect on organizational commitment and job satisfaction. Job satisfaction also had a positive and significant effect on organizational commitment and mediated the relationship between perceived organizational support and organizational commitment. The research model explained 72.1% of the variance in organizational commitment. These findings highlight the importance of organizational support, fairness, and recognition in improving nurses’ satisfaction and organizational commitment.Penelitian dilatarbelakangi oleh rendahnya dukungan dan pengakuan organisasi yang dirasakan perawat, sehingga berdampak pada menurunnya kepuasan kerja dan komitmen organisasi.
