Judul: Analisis Kestabilan Model Virus Komputer dengan Infeksi Tunda dan Pemulihan Tunda.
Abstrak: In this paper, a dynamical model is composed of computer virus model that considers time delay of infection and recovery processes. Stability analysis is performed to both models, i.e. the models with and without time delay. The model without time delay has two fixed points, which one of them is stable and the other is unstable. On the other hand, the model with time delay has fixed points which one of them is spiral stable. If the value of time delay is sufficiently large, then it will imply the stability changes from spiral stable to spiral unstable and subsequently the appearance of limit-cycle and Hopf bifurcation.
