This study aims to describe the forms of linguistic hybridity and identity negotiation through the mixed use of digital slang codes among seventh grade students at SMP N 3 Gantung. This study employs a qualitative approach with a descriptive method. The research data were obtained through observations, interviews, and audio recordings of students’ interactions in the classroom environment. The data analysis technique used the miles and Huberman model, which includes data reduction, data display, and conclusion drawing. The results of the study show that students actively use a mixture of Indonesian, English, and Belitung Malay codes in their daily communication. The use of mixed languages functions as a communication tool, a marker of modern adolescent identity, a symbol of group solidarity, and a form of negotiation between local and global identities. The factors causing linguistic hybridity are influenced by internal factors, such as adolescence, the need for self-existence, and peer group influence, as well as external factors, including social media and the surrounding environment. Based on these findings, it can be concluded that the development of digital culture does not eliminate students’ local identity, but instead creates hybrid communication practices that integrate local, national, and global elements in daily.
