Death is the end of life in a biological organism. All living things will eventually die. Humans are also living beings, so humans also experience death. Babies are humans, so babies will also experience death. Infant mortality is influenced by two factors, namely factors before and after birth, which before birth is the consumption of pregnant vitamins, births assisted by medical personnel, wh…
The final project presents a new approach to evaluate the cubic roots of a quadratic matrix order 2 by using the Cayley-Hamilton’s theorem. In addition, this final project also aims to show how the Cayley-Hamilton’s theorem can be used to determine the explicit formula of each cubic roots of quadratic matrix. In its application several examples are given to determine the cubic roots of …
This final project discusses the interactions among three population consisting of prey 1, prey 2, and predator population. The model described involves the prey 1 population influenced by Allee effect. Prey 1 and prey 2 population have a mutuality according to Holling functional response, while the predator population has alternative food sources. In the model observed, there are eight eq…

This model aims to determine optimal policy of inventory problem by meeting the specified constrains. The mathematical model for this problem is designed using the LINGO 18.0 application. The solution of the assignm…
This final project discusses the inventory management of resources with discount of raw materials. In this discussion, it is used the economic order quantity model with discount to determine how much to order, so as to minimize the total inventory costs. The result of this problem is the total inventory cost which is smaller than the previous policy. Keywords: Inventory, inventory manageme…
This nal project discusses the multiplication of a Pell numbers and a Pell-Lucas numbers generating a power numbers. The power numbers is the repeated product of a numbers, with a positive, zero, or negative integer power. Power numbers are obtained if they satiss the condition n > m > 0, and n ≡ m(mod 4) or n ≡ m+2(mod 4) and satiss the solution of (N,M) for N ≤ 14 and M ≤ 7. K…
This nal project discusses the properties of BI -algebra and properties of ideals in BI -algebra. By using the binary operations and implication algebra are obtained by conditions that show the properties of BI -algebra and Ideals in BI -algebra. This nal project is a review of article from Saeid et al. [Analele Stiintice ale Universitatii Ovidius Constanta, 2017, 177-194]. Keywords: BI…
This research is motivated by the low ability to solve mathematical problems and the limited learning tools based on the 2013 Curriculum, especially those that apply the Problem Based Learning (PBL) model. Based on these conditions, it is necessary to develop learning tools in the form of syllabus, lesson plans, and LKPD to assist teachers in learning. The purpose of the research is to pro…
This nal project discusses the solution of solid transportation problem of triangular fuzzy numbers. Triangular fuzzy numbers are converted into rm numbers and paramaters. Furthermore, to nd the optimal solution, an approach for solving the solid transportation problem is used. Based on the comparison of two forms, it is concluded that the parameter form can be used as an alternative in…

The implementation of the 2013 curriculum well is very much determined in developing learning tools. This research produces learning tools in the form of syllabus, lesson plans, and student worksheets with Problem Based Learning models on Social Arithmetic material. This research is a research and development (R&D) using a 4D model. The instrument in this study was a validity instrument in the …
Mathematical reasoning abilities (MRA) are needed and becomes the base of problem-solving skills because mathematical reasoning and mathematics lessons are two related things. Solving mathematical problems requires reasoning and reasoning skills can be honed from learning mathematics The low ability of mathematical reasoning is seen in the geometry material so innovation is needed to improve th…
The learning tool (Silabus, Study Implementation Plan (RPP) and Student Activity Sheet (LAS) mathematics apply the Problem Based Learning model to facilitate the study KPMM students on material quadratic equations to use.However, valid and practical grade IX junior high school/MTs students are not required to participate in the study. The purpose of this research. This type of research is …
Abstract : This research is classroom action research that aims to improve learning process and to increase mathematics achievment with applied the learning model of Problem Based Learning.

The final project discusses a modification of gradient projection method to solve linear programming and sensitivity analysis. This method is an iterative method in which the search for the optimal solution is based on tracing the points in the feasible region. In addition to determining the optimal solution, this method is also used to perform sensitivity analysis on changes in the coeffic…
The purpose of this research is to produce mathematics learning media using geogebra software to facilitate students' interest in learning in valid and practical class VII SMP/MTs quadrilateral material. In addition, as an aid to find out the truth of the principle, as a form of object mathematical skills (procedures). The development model of this research is a 4D model, namely define, design,…
In curriculum 2013 it has been suggested that one of the aims of mathematical learning: learners is expected to have problem-solving ability. Teacher is expected to increase the activation of learners in the learning process especially the development of the ability to solve mathematical problems. In this regard, the aims of this study is to produce a product of learning tools (silabus, RPP…
