Penggunaan Metode Homotopi untuk Menyelesaikan Model Aliran Polutan di Tiga Danau yang Saling Terhubung

Abstract

Pollution of lake is a very serious threat to the environment. One way to monitor pollution on lakes is constructing a mathematical model. The model of spreading pollution on interconnected three lakes is solved by using homotopy method. In homotopy method, it is defined as an operator based on differential equation forms in mathematical models. The result of this method is compared to the result of the perturbation homotopy method published by Merdan (2009). The graph of spreading pollution function on interconnected three lakes is based on the forms of pollution sources at the first polluted lake.
