Penelitian ini didasari dari fenomena pemodelan matematika yang senantiasa menggu- nakan nilai parameter tanpa adanya fitting data. Fenomena yang terjadi pada dunia nyata yang kemudian dimodelkan dalam persamaan matematis ...

This article discusses the development of a family derivative free iterative method with nine parameters for solving nonlinear equations. Analytically it is showed that this iterative method has the order of convergence six. ...

This article discusses a new family of three-step iteration method. Analytically, it is showed using Taylor expansion and geometry series that this iterative method has a convergence eight-order. Numerical comparisons ...

Model Predator-Prey digunakan dalam mendeskripsikan perilaku populasi yang memiliki hubungan mangsa dan pemangsa. Model yang biasa digunakan selalu mengasumsikan bahwa mangsa dan pemangsa dalam kondisi sehat. Pada artikel ...

Predator –prey model is used to analize behaviour of interaction two population which are predator and prey. Basically, this model assume both of predator and prey are healthy. In this article, we develop alternative ...
