<![CDATA[The development of online gaming platforms has encouraged the emergence of virtual communities that facilitate intensive social interaction. One of the most widely used platforms is Roblox, which functions not only as a gaming medium but also as a space for communication and interpersonal relationship building. This study aims to examine the influence of virtual interaction on the Roblox platform toward self-confidence in interpersonal communication among members of the TGRC community. The study is grounded in Computer-Mediated Communication (CMC), Social Penetration Theory, and Social Cognitive Theory to explain the process of virtual communication and the development of self-confidence. This research employed a quantitative explanatory approach by distributing Likert-scale questionnaires to 136 TGRC community members selected through purposive sampling. Data were analyzed using IBM SPSS Statistics Version 26, including validity and reliability tests, classical assumption tests, simple linear regression analysis, F-test, t-test, and coefficient of determination. The findings indicate that virtual interaction on the Roblox platform has a positive and significant effect on self-confidence in interpersonal communication. Higher levels of virtual interaction are associated with greater self-confidence in communicating with others. These findings suggest that virtual interaction can serve as an effective medium for enhancing individuals' interpersonal communication skills within online communities.]]>
