The integration model between Technology Readiness Index, Technology Acceptance Models, and Theory of Reasoned Action expanded with Motivation increases digital literacy, while government support positively influences the variable. The model emphasizes optimism and innovation as key factors in enhancing the construct of Technology Readiness Index model. The results show that there is a strong foundation for the establishment of Technology Acceptance Models and Theory of Reasoned Action expanded with Motivation aimed at supporting digital literacy.
