This final project discusses the generalization of the Sylvester matrix of order (n+1) (n+1) with main diagonal alternating x and x, its upper subdiagonal n, (n 1), . . . , 1 while its lower subdiagonal 1, 2, . . . , n. The proof is carried out by partitioning the matrix into 2 2 block matrices, which are divided into two cases namely when n is odd and when n is even. This matrix partition aims…
This final project discusses a new sixth-order iterative method free from second derivative to solve a nonlinear equation. The method is obtained by Taylor’s expansion, then the second derivative that appears in the formula is appro- ximated using a cubic polynomial with Hermite orthogonal polynomial basis. Analytically using the Taylor’s expansion and geometric series that iterative method…
This final project discusses the analysis of mathematical models in territorial waters with two different treatments. In this model the system of differential equation for the mathematical model uses two regions, namely free and protected territory. The observed model consists of two equilibrium points. Stability analysis is performed using the Routh-Hurwitz Criteria. Finally a simulation …
Life insurance is a protection program for individuals or families from death that can cause financial loss. Insurance companies need to calculate reserves to prepare funds when participants request a claim. This final project discusses the prospective reserve of joint life endowment life insurance for two insurance participants who are x and y years old by using Joe copula model. The solution …
This final project discusses the control of raw material inventory to determine the optimal order quantity per order, in order to be able to minimize the total inventory cost. The method used in this final project is the EOQ multi-item model and min-max stock method based on data on seven types of raw materials for making electrical panels consisting of the amount of inventory of each item, t…
One of the objectives of learning mathematics in the independent curriculum is to equip students with mathematical creative thinking skills. However, the facts indicate that the level of students' creative thinking skills is still low. The reason is because students are not accustomed to facing contextual problems that demand creativity, argumentation and reasoning, and the use of LKPDs that ar…
The purpose of this development research is to produce discovery learning-based LKPD that can facilitate the mathematical critical thinking skills of phase D students by fulfilling valid and practical requirements. The background of the research begins with the importance of students' critical thinking skills. This research method is a development research (R&D) with the 4- D model (define…
This thesis discusses a derivative free three-step iterative method to solve a nonlinear equation using Steffensen's method, after approximating the derivati- ve in the method proposed by Abro and Shaikh [Appl. Math. Comput.,55(2019),516- 536] by a divided difference method. This study shows analytically that the method is of order sixth under a condition and for each iteration it requires …
Mathematical representation skills are one of the skills that students must have in learning mathematics. Learning that facilitates mathematical representation skills can build students' knowledge and understanding of mathematical concepts. Mathematical representation skills are the foundation for how students understand mathematical ideas and use them so that mathematical representations have …
Algebra for interval numbers has been developed by various authors. For the operations of addition, subtraction, and scalar multiplication, there aren't many differences among the numerous algebras for interval numbers. However, other algebraic alternatives are offered by various authors for division/inverse operations and multiplikation. All of the provided algebras, however, are irrelevant to…

The subject of this research consist …
This final project discusses the new iterative method using weight function for solving nonlinear equations. The convergence analysis using Taylor expansion and geometric series shows that the proposed method has a fifth order conver- gence with efficiency index is 1.495348781. Numerical computational results of some examples with several different types of fifth order methods show that in gene…
This final project discusses the hybrid Steffensen method (MSH) as a new ite- ration formula obtained from a convex combination of the Steffensen forward method (MFS) and Steffensen backward method (MBS) for a parameter ω with 0 ≤ ω ≤ 1. Based on the analysis of the convergence, it shows that MSH has a quadratic order of convergence. Then from the results of computational tests through co…
This final project discusses the mathematical modeling of the nurse scheduling problem in one working day period, using the integer linear program method by meeting the existing constraints. The mathematical model in this problem is assisted by the LINGO application. In this study, the number of working days of each nurse with the same total working days was obtained. The mathematical model in …
In life insurance companies, to anticipate the possibility of company losses when the policyholder dies without sufficient funds because the company must pay the sum insured to the heirs. The company needs to prepare reserve costs to ensure that the company has sufficient funds to pay for the needs of the insuran- ce company and insurance participants. The objective is to determine the full pre…
This final project discusses the quadratic programming problem of linear con- straints and solves it using the Kuhn-Tucker condition method. This method starts by changing the inequality constraint into an equation using the additio- nal function of the Lagrange multiplier. The multiplier is used to convert the extreme point of a constraint function into a point. Each Lagrange multiplier must s…
This final project discusses the problem of mixed constraint linear programming and solves them using the Lagrange multiplier method. Linear programming is used to solve problems in everyday life. Problems that are often associated with linear programming are always related to various fields of economics such as problems that often occur in home industry businesses, namely the insta- bility o…
This final project discusses the dynamics of a predator-prey model involving interactions between predator and prey populations. This interaction is influ- enced by the fear effect on prey which causes prey to migrate to safer patches. Predator density decreases when the level of fear effect increases. Migration be- tween patches also has a large impact on predator density. The model is solved …
