The low ability to solve students' mathematical problems in the Flat-Side Building material is due to the limited learning tools used in mathematics learning according to students' needs. This research aims to produce mathematics learning tools in the form of a syllabus, lesson plans and worksheet using the Problem Based Learning model in the Flat-Side Space Building material for class VIII SMP…
This final project discusses the solution of fractional linear programming using dynamic programming forward methods. The solution to this problem is to find the optimal solution of the fractional linear programing by changing the fractional objective function to an approximation function using the simplified method, followed by using the simplex method until the optimal solution is obtained. T…
Global climate change can lead to extreme weather events that often lead to losses. One of these extreme weather events is the storm rainfall. Therefore, it is necessary to model rainfall that can describe the characteristics of rainfall data as well as predict the same extreme events in the future. The research involves the modeling of storm rainfall, with data obtained using storm analysis…

The development is carried out demonstrates the relation that forms between the radii of mixtilinear incircles and excircles that can be constructed on the angle bisectors of ABC. Then points are constructed D on side BC so that AD = d divides ∠A equally, in each triangle, three different m…
A new approach is presented in this final project with the purpose of calculating the square roots of a quadratic matrix order 3. In this final project, the Cayley- Hamilton Theorem is applied to the characteristic polynomial of the square roots of a quadratic matrix order 3. In addition, this final project is also aims to determine the explicit formula of each square roots of a quadratic matri…
This final project discusses the dynamics of the predator-prey model with prey refuge and considers the effect of fear. The observed model has four equilibrium points where two points are unstable and other points are stable under certain conditions. Simulation of the model is carried out with spesific parameters to describe the behavior and stability of the equilibrium points. Based on results…

Comparisons of computational tests shows that a new family of optimal fourth-order iterative methods can be used as an alternative in…
This final project discusses a two-step iterative method for solving nonlinear equations. This method is obtained by modifying Newton’s method using a weight function. Analytically, it is shown that using Taylor expansion and geo- metric series, this iteration method has a convergence order of five and requires four function evaluations for each iteration. This fifth order iteration method ha…
This final project discusses the formula determinant and characteristic polyno- mial for the Lucas-Sylvester-Kac matrix of order n n. The solution is obtained by using the application matrix centrosymmetric form, and in this final project also considers two cases, namely when the Lucas-Sylvester-Kac matrix has even order n and when the Lucas-Sylvester-Kac matrix has odd order n. Characte- risti…
Life insurance is a protection effort provided by the insurer against risks to the insured’s life that will arise from an unpredictable event. Insurance companies need to calculate reserves to prepare funds when participants request a claim. Zillmer’s reserves are modified reserves that are calculated using prospective reserves and a zillmer rate of β.This final project aims to determin…
The welfare of workers at retirement age is an important factor in ensuring fulfillment of needs in old age, especially workers who work for a company or a government agency. Workers must have an early plan that can guarantee future welfare when entering retirement age. Given the economic development and technological advances that will trigger an increase in needs, a worker will certainly not …
