Abstract The goal of this research is to know about main criteria that is considered by the graduate of Mathematics Study Program, Faculty of Mathematics and Science, State University of Padang in choosing a job in Badan Usaha Milik Negara (BUMN) using Analytical Hierarchy Process (AHP) method. The data is collected from opinion of respondents which is the September 2012 period graduates in pairwise comparison questionnaire form using Saaty’s scale (1-9). The main result of this research is the graduate is more consider about their carrier in the future (31,2%) in the BUMN Persero that they choose, then followed bysalary, image and placement. Then the other one shows that Pertamina (34,5%) is the first priority as a job choice, followed by Perusahaan Listrik Negara, Telkom, Garuda Indonesia, Bank Tabungan Negara, Pos Indonesia, Asuransi Jasa Raharja, and the last one is Pembangunan Perumahan. Keywords Analytical Hierarchy Process, priority, job choice

Abstract- Effect of season is one of the factors that need to be noted in the predation. In this study, used the four seasons, summer, winter, spring, and autumn, where the amount of predation different every season. The study began by establishing a mathematical model of predation to the effect of the season. In this model, the population is divided into two, prey populations and predator populations. With useful analysis model using perturbation theory note that the effect of the season had a significant effect on the growth patterns of prey and predator populations, where at any given time pattern of prey and predator population Growth Is changing. Keyword :Predator-Prey, Seasonal effect, Mathematical models, Perturbation theory.

Model Matematika Populasi Plankton dan Konsentrasi Nitrogen Elvi Silvia; Yarman Yarman; Muhammad Subhan

Abstract – Phytoplankton and zooplankton have a major impact on the marine ecosystem because plankton is the main food chain in the ecosystem. However, this plankton’s concentration changes is influenced by nitrogen concentrations. This study began by making mathematical model based on the variables , parameters and assumptions that have been determined. Next step are finding and analyze an equilibrium point. Mathematical model in plankton populations and nitrogen concentration in the form of non-liner differential equation system. This dinamical system have two equilibrium points ie the points where nitrogen without plankton and the point where nitrogen and plankton. The stability of the system can be viewed from two condition, first when the system has one point where nitrogen without planktonthen this point will be stable. Second, when the system have two equilibrium points then only point where nitrogen and plankton will be stable. This result show that population of phytoplankton, zooplankton and nitrogen concentration will not disappear in the long term. Keywords – Nitrogen, plankton, mathematical model

Penyelesaian Sistem Persamaan Linear (SPL) Dengan Dekomposisi QR Shelvia Mandasari; Muhammad Subhan; Meira Parma Dewi

Abstract – QR decomposition is a numerical method to solves a System Linear Equations with n equations and n variables. This decomposition obtained by Gram Schimdt process and inner product space. From that method make an algorithm, that has been made a computer program to solve that System Linear Equations with n equations and n variables. The solution that obtained by this decomposition more accurate with small errors because this method only use two process so this decomposition more effective than that other numerical method. Keywords -- Inner Product Space, Gram Schmidt Process, QR Decomposition

Mathematical problems in determining the roots of nonlinear equations can be solved analytically and numerically. However, very complex nonlinear equations are difficult to solve analytically, so numerical methods are used. Trapezoid Second Order Iteration Method is a method that emerge because of the shortcomings of the Newton Raphson Method and The Secant Method. The purpose of this study is to examine the process of forming the formula for the Trapezoid Second Order Iteration Method, develop an algorithm and find its convergence. This type of research is basic research. The result of numerical simulation tests on several function whose approach point are at two peaks show that The Trapezoidal Second Order Iteration Method is faster than Newton Raphson Method.
