The background of this research is due to the low Algebraic Thinking Ability (KBA) of students. This study aims to produce valid and practical mathematics learning tools to facilitate students' KBA on the material of the Two-Variable Linear Equation System in class VIII SMP / MTs Pekanbaru. This learning device development research uses ADDIE model development research (Analysis, Design, Devel…
This research was motivated by the low mathematical problem solving ability of students, especially in rows and series material. Efforts that can be made to facilitate mathematical problem solving skills are to design learning activities to make students accustomed to solving contextual problems given by applying problem-solving steps. One learning model that can help students in building mathe…
This thesis discusses the development of the outer and inner Cross’ Theorem on a crossed quadrilateral, by which it is expanded once and twice by constructing a square towards the outer and towards the inner on each side of the crossed quadrilateral theorem. The proof process is done using the sine and cosine rules. The result obtained for the outer and inner are the absolute differences …
ABSTRACT This nal project discusses an iterative method that uses geometric construction to solve a nonlinear equation. The method is obtained by consructing the curve of a third degree monic polynomial function that approximates the curve of the nonlinear equation. The convergence analysis shows that the iterative method has third-order of convergence. Some numerical examples are given t…
ABSTRACT This final project discusses the 2×2 singular matrix with zero second row entries or a matrix with all nonzero entries are formed as the product of two idempotent matrices or two nilpotent matrices. To solve this can used the division algorithm and algebraic methods to obtain a special matrix that can be formed into the product of two idempotent matrices or two nilpotent matrices…
Mathematical Reasoning Ability (MRA) is an important ability for studentsin mathematical learning. However, students' MRA is still in the low category due to the lack of test instruments that teachers can use as a reference for training students' MRA. This study aims to develop a MRA test instrument on sequences and series material that are valid, reliable, and has a good level of difficulty an…
Improving the learning process and increasing students' mathematical problem solving abilities (KPMM) by applying the problem based learning (PBL) model are the main objectives of this research. The research applied is PTK with two cycles which are carried out in the even semester of the 2022/2023 school year. Class VII-E students of SMP Negeri 23 Pekanbaru were the subject of this study with a…
Mathematical literacy skills are very essential for students. Not only understanding math, but students must also be able to interpret math in real life. However, in reality, students' mathematical literacy skills are still relatively low. Many learners have not been able to find solutions to contextual problems and there are limited Learner Worksheets (LKPD) used by learners in facilitatin…
This development research aims to produce learning tools including syllabus, learning implementation plans (RPP) and student worksheets (LKPD) that are valid and practical based on the Problem Based Learning (PBL) model to facilitate the mathematical problem solving abilities (KPMM) of class VII students SMP/MTs on comparative material. This development research uses a 4-D model (Define, De…
The cause of the low KPMM students is that students only memorize the formulas that the teacher gives without understanding the systematics concepts in the implementation of learning. Another thing, because students have not been able to do questions that are different from the example questions the teacher gives. KPMM can be developed throght the implementation of learning, namely by giving st…
ABSTRACT This final project discusses the annual premium on endowment last survivor life insurance using Rayleigh distribution. The insurance participants are limited only for two persons who are x and y years old. The premium payment stops if the last person of its member dies or term of payment ends. The chance of life and chance of death of insurance participant are determined using Ray…
Strategic location of facilities and effective and efficient distribution of commodities are aspects of successful management in a company. This thesis discusses the selection of locations for several facilities by considering the route of commodity distribution to consumers served by a certain facility. This problem is solved using the Weiszfeld’s iteration method to get the local optima…
This research is motivated by the difficulties experienced by teachers in developing learning tools that are in accordance with the 2013 curriculum. A learning tool is needed so that it can increase student understanding and familiarize students with solving problems in everyday life. This study aims to produce a syllabus, lesson plans, and LAS with a problembased learning (PBM) model on th…
This research is motivated by the low ability of students' mathematical connections in quadrilaterals and triangles. This is influenced by teaching materials in schools, namely LKPD which does not yet facilitate mathematical connection abilities. Another factor is that students are not used to working on mathematical connection ability questions so that students have difficulty in associating b…
MAAF, UNTUK ABSTRAK TIDAK TERSEDIA NB: PERPUSTAKAAN UNRI CONTENT DIGITAL
The COVID-19 pandemic hit the world in early 2020 and caused many deaths in various countries, one of which was Turkey. In March 2020, the first case of COVID-19 was confirmed by the Turkish Ministry of Health. In May 2021, the rise of cases continued to occur until it reached 5.2 million cases with a death toll of 47,271 people. In this research, a model for Turkey’s COVID-19 positive ca…
ABSTRACT This final project discusses the premium reserve of term life insurance for single insurance participant who are x years old using prospective method and the calculating reserve is based on semi-Markov assumptions. The solution to the problem is to obtain by determining the annuity continuous, single premium, and annual premium then to obtain the premium reserve formula base on th…
This thesis discusses the general inverses and inverses of triangular fuzzy matrices. Suppose ~u = (u; ; ) any triangular fuzzy number that is converted into a fuzzy interval form to determine the middle value, or m(~u), of the fuzzy number. The middle value is used to construct multiplication, division, and inverse fuzzy numbers. Furthermore, the constructed arithmetic is used to determ…
The purpose of this research is to develop mathematics learning device that are Lesson Plan (LP) and Students Worksheet (SW) on subject quadrilateral through the implementation of Discovery Learning for grade VII SMP/MTs with minimum valid criteria. This research method used ADDIE model that consist of analysis, design, development, implementation and evaluation, but the reserch only done …
