Analisis dinamik model predator-prey tipe Gause dengan wabah penyakit pada prey

This article studies the dynamics of a Gause-type predator-prey model with infectious disease in prey. The constructed is deterministic which assumes prey divided into two compartments i.e. susceptible and infected prey, both them are hunted by predator bilinearly. It investigated that there exist five biological equilibrium points such as all population extinction point, co-existence point. We find point always unstable while others conditionally locally asymptotically stable. Numerical simulations, well phase portraits, given to support analytical results.
