This study aims to analyze the effect of social communication on sustainable territorial performance at the Iskandar Muda Military Command in Aceh. The research sample consisted of 326 Village Supervisors (Babinsa) who were recruited through an invitation to complete a questionnaire distributed via official TNI communication channels with a survey link on Google Forms. Data were collected using a structured questionnaire designed to gather demographic information of respondents and research variables, including social communication, sustainable territorial performance, territorial responsiveness, and territorial loyalty. The questionnaire consisted of two parts, utilizing a 5-point Likert scale to measure respondents' levels of agreement with the statements. Data analysis was conducted using Structural Equation Modeling (SEM) with a Partial Least Squares (PLS) approach. The results indicated that territorial responsiveness and territorial loyalty do not mediate the relationship between social communication and sustainable territorial performance. However, both variables have a direct positive and significant impact on sustainable territorial performance. Additionally, social communication was found to have no direct effect on sustainable territorial performance, territorial responsiveness, or territorial loyalty. These findings provide important insights into the relationship between social communication and territorial performance, as well as implications for management practices in military settings.
