Abstract

Dengue is one of the infectious diseases transmitted to humans by the bite of Aedes aegypti or Aedes albopictus mosquitoes. Dengue virus infections include dengue fever, dengue hemorrhagic fever and Dengue Shock Syndrome (DSS). The dengue virus has four types of serotypes: DEN_1, DEN_2, DEN_3, DEN_4. In the model, will be studied the dynamics of the spread of dengue hemorrhagic disease type SEIR. From the model then fixed point will be determined, then analyzed the stability of each fixed point by considering the basic reproduction number (R_0 ). The results showed that for fixed point without disease the condition would be stable when R_0<1, while the fixed point of endemic would be stable for condition whenR_0>1.

Abstract

This research discusses the numerical solution of the infiltration problem of the periodic flat channel and is solved using the Dual Reciprocity Boundary Element Method (DRBEM) numerical method with polynomial radial basis functions. DRBEM is a development of the Boundary Element Method, used for PDP solutions in the fields of mathematical physics and engineering. DRBEM has an important role in obtaining a solution to the Helmholtz equation by describing the reciprocal relation between the fundamental solution of the Laplace equation and the solution to be sought. Furthermore, the term containing the double integral in the calculation is approximated by the radial basis function, in order to obtain an equation containing only the boundary integral. The objective of the obtained numerical solution is then compared with the analytical solution obtained by Batu, in order to obtain an accurate solution of the polynomial radial base function for solving the infiltration problem. The mathematical models used in the infiltration problem are the Richards equations, Kirchoff transformation and the dimensionless variables for obtaining the modified Helmholtz equation. The results of the calculation of the numerical solution have shown that the DRBEM with the radial polynomial base function for the number of boundary elements resulting from the discretization and the number of interior collocation points at (N = 200, L = 400) and (N = 225, L = 400) obtained the approximate value ( error) from the six points in the region, indicating that the greater the value of N, the smaller the error. So that for FBR, and the one with the smallest error is , it means that it is close to the FBR used by Batu, is .. Thus, it is concluded that the more discrete line segments result in the region boundary, the numerical solution will approximate the analytical solution. Keywords: Infiltration, modified Helmholtz equation, FBR, DRBEM.

Abstract

Smoking is the activity of burning tobacco then sucking the smoke and releasing it back through the mouth. This study examines the spread of smoking behavior based on economic factors and psychological factors. This model divides the population into 4 subpopulations, namely potential smoker , Beginner smoker , Smoker subpopulation and recovery subpopulation The stability of the smoking-free equilibrium point is obtained by linearizing the equation to obtain the Jacobian matrix and then the eigenvalues will be obtained. The basic reproduction number which is the threshold for the spread of smoking behavior where smoking behavior will disappear if Ro < 1 and will be endemic when Ro > 1.

Abstract

Assignment problem is one part of linear programming that can be found in real life. The Assignment problem includes m workers who have n tasks assuming n=m. The division of work is seriously handled by the company so that each employee gets an equal amount of work hours that are determined. This study aims to optimize employee assignments based on minimum operational costs and minimum job completion times using the Hungarian method. Optimization is a mathematical approach that deals with maximum and minimum problems. From the results of the study, after using the Hungarian method, the work completion time on the Kefamenanu Supermarket Metro was 9: 34: 20 (in hours, minutes, seconds). The total operational costs of work incurred by the company if calculated using the Hungarian method with MATLAB software, the results are Rp. 11,141. Furthermore, the order of minimization of employee assignments is obtained as follows: II, VII, I, IV, VI, V and III.
