Abstract

Mathematical model has many benefits in life, especially the development of science and application to other fields. The mathematical model seeks to represent real-life problems formulated mathematically to get the right solution. This research is the application of mathematical models in the field of biology that examines the interaction of the two populations that host populations and parasitoid populations. This study differs from previous studies that examine the interaction of two more species that prey and predators where predators kill prey quickly. In this study the parasitoid population slowly killing the host population by living aboard and take food from the host population it occupies. In this study of differential equations are used to construct a mathematical model was particularly focused on the stability of the local mathematical model of interaction of two differential equations that host and parasitoid populations. Stability discussed in this study are stable equilibrium points are obtained from the characteristic equation systems of differential equations host and parasitoid interactions. Type the stability of the equilibrium point is determined on the eigenvalues of the Jacobian matrix. Analysis of stability is obtained by determining the eigenvalues of the Jacobian matrix around equilibrium points. Having obtained the stable equilibrium points are then given in the form of charts and portraits simulation phase to determine the behavior of the system in the future.

Abstract

Mathematics is a subject that has the concept of interrelation between one material with another. Understanding the interrelated material required the existence of a basic ability that is the ability to connect mathematics. The obstacle experienced by students is that when given a problem and the solution is related to the previous material, students are unable to remember the material that is the key to solving the problem. The inability of students is due to lack of memory of previous material and students pay less attention when the teacher is explaining in class. Personality differences make students have different mathematical connection abilities. The purpose of this study is to describe the ability of students' mathematical connections in terms of sanguinis, koleris, melancholy, and plegmatic personality types. This type of research is a qualitative descriptive study in the form of case study research. Methods of data collection used personality type questionnaires, math connection test questions, and interviews. The results showed that the sanguinis and plegmatic personality types were able to meet all the connection indicators. Koleris personality type is able to fulfill 4 indicators. Melancholy personality types produce different connection capabilities, namely the ability of connections that meet 4 indicators and 1 indicator. This research can provide benefits for students to improve their mathematical connections and understand their personality types. Students who understand their personality types can minimize negative traits that inhibit mathematical connections.
