Abstract

4-D (Define, Design, Develop and Disseminate) Method used in this research. This research has made an android based application. The application that has been made is the development of mathematical theories that have been found by previous researchers. The Application that has been made can solve minimize rental cost on flowshop scheduling problem. This study uses simulations to conduct trials on applications that have been made. This Application is expected to make industrial revolution era 4.0’s dreams come true.

Abstract

We studied the Lotka Volterra predator-prey model with linear harvesting of prey and predators. We found that there are 3 equilibrium points, namely the point of extinction of the two species, the point of extinction of predators and the point of coexistence of both species, predator and prey. The stability and existence of the three points depend on the parameter values in the model. We found that the populations of both species were sustainable if the growth rate of the predators was greater than the mortality and yield rates of the predators. Overharvesting led to the extinction of both species. We also perform numerical simulations using the Python programming language to see the system behavior graphically
