Second Order Runge-Kutta Method in Solving Renewable Natural Resources Model Case Study: Fishes and Water Resources Management

This research presents a study of dynamical system which models natural resources. Using fishes and water resources as the case study. In this work model equation was used to determine density We also introduced second stage Runge Kutta method, obtain result for harvesting terms from 10% 50% producing population life in pond after each harvesting.
 work, solution dynamic that can using Runge-Kutta method reported. To actualize result, model, first order ordinary differential famous is used. Harvesting iteration demonstrate validity result. The applied fish pond, renewable resource, with great success.
 line objectives stated at beginning results has shown by applying be obtained success.
