<![CDATA[Personnel retention is a strategic issue in human resource management within the Indonesian National Police, particularly for the Banten Regional Mobile Brigade Unit (Satbrimobda Banten), which is characterized by high-risk duties. This study aims to analyze the influence of career development and perceived organizational support on job satisfaction, as well as their impact on personnel retention within Satbrimobda Banten. A quantitative approach utilizing a survey method was employed. The study population consisted of all Satbrimobda Banten personnel, with the sample selected via proportionate stratified random sampling. Data were collected using a five-point Likert scale questionnaire and analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS) with SmartPLS software. The results indicate that all hypotheses were supported. Career development and perceived organizational support were found to have a positive and significant influence on job satisfaction. Furthermore, career development, perceived organizational support, and job satisfaction positively and significantly influenced personnel retention. Job satisfaction was shown to significantly mediate the effects of career development and perceived organizational support on personnel retention. Perceived organizational support emerged as the most dominant variable influencing both job satisfaction and personnel retention. These findings reinforce Organizational Support Theory and Social Exchange Theory, highlighting the importance of strengthening organizational support, ensuring transparency in career development, and enhancing job satisfaction to bolster personnel retention.]]>
