Dynamical Analysis Discrete of Euler Scheme for Harvested Predator-Prey Model with Ratio-Dependent Response Function and Prey Refuge
A Hadi, Abdul Hadi, Siti Nurul Afiyah, Vivi Aida Fitria
In this research, Euler method is applied to discretize a harvested predator prey model with ratio-dependent response function and prey refuge. The existence and stability of fixed points has been analyzed. Stability of each fixed point shown that the fixed points are stable for small size of time step....

Applying Spherical Triangle Concept in Simulator to Determine Distance and Direction of Ship
Damoyanto Purba, Novita Hindri Harini, Agus Dina Mirianto, Zainullah Zuhri
Since Electronic Chart Display and Information System (ECDIS) is a very important navigator for the safety of seafaring, a cadet of Seafaring Polytechnic should learn it at class. Cadet should master how to use it properly to improve effectiveness and efficiency in seafaring. But, ECDIS only in the ship...

A Numerical Study of Diffusion-Convection Equations
Imam Solekhudin
In this paper, problems involving time-dependent diffusion-convection equation are studied. To study these problems, a numerical method is employed to solve the equation numerically. The method used in this research is a Laplace Transform Dual Reciprocity Method (LTDRM). Using this method, the time-dependent...

The Fuzzy Optimal Solution of Fuzzy Transport Problems Using A New Fuzzy Least Cost Method
Farikhin Farikhin, Muhammad Sam'an, Bayu Surarso, Bambang Irwanto
The fuzzy transport algorithms is used by researchers for finding optimal solution of Fuzzy Transport Problem (FTP), one of them is the Least Cost Method or LCM. The concept of LCM is to choose the least cost from the FTP table to be used as the base cell. If there is the same lowest cost, it is freely...
