<![CDATA[Digital transformation in higher education requires the availability of academic information systems that are not only high quality but also capable of protecting students' digital data and activities. This study aims to analyze the influence of information system quality and cybersecurity perceptions on student continuance usage, both directly and indirectly through trust as a mediating variable. The study used a quantitative approach with a survey design on 216 active students of the Muhammadiyah Polman Institute of Technology and Business who have used the Academic Information System. Respondents were selected using a purposive sampling technique. Data were collected through a five-point Likert-scale questionnaire and analyzed using Partial Least Squares–Structural Equation Modeling with the help of SmartPLS 4. The results showed that information system quality had a positive and significant effect on trust (β=0.339; t=6.325; p<0.001) and continuance usage (β=0.222; t=3.903; p<0.001). Cybersecurity perceptions also had a positive and significant effect on trust (β=0.387; t=6.174; p<0.001) and continuance usage (β=0.275; t=5.528; p<0.001). Trust exerted the strongest influence on continuance usage (β=0.427; t=7.745; p<0.001). Furthermore, trust was shown to partially mediate the effect of information system quality on continuance usage, with an indirect effect of 0.145 and a VAF of 39.4%, and the effect of cybersecurity perceptions on continuance usage, with an indirect effect of 0.165 and a VAF of 37.6%. This study concluded that the continued use of academic information systems is determined by technical quality, cybersecurity assurance, and especially student trust. Universities need to improve system reliability, data protection, security transparency, and service responsiveness to maintain continued system use.]]>
