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 …
The background of this study is the restrict of mathematics learning device as supporting learning referring to 2013 Curriculum. This researches aims to develop mathematics learning device form of syllabus, RPP and LKPD with problem based learning model on the subject matter of the social arithmetic the 7th grade students of SMP/MTs. Research development by Thiagarajan. Development is done thro…
ABSTRACT This final project discusses Zillmer reserve of endowment insurance for insurance participant who are x years old using the interest rate model of Vasicek and Weibull distribution, where parameters in the model are estimated using maximum likelihood method. Solution of this problem is obtained by determining the single premium, annual premium, and life annuity. Then the reserve f…
ABSTRACT This final project presents a new approach to evaluate the integer positive po- wers from tridiagonal matrices by using Chebyshev polynomials. In addition, this This final project also aims to show how the Chebyshev polynomial can be used to determine the formulation of the transformation matrix and the inverse of the transformation matrix
ABSTRACT This final project proposes a new iteration method to be formed by using Taylor expansion and derivative approximation for solving nonlinear equations with convergence order is four and efficiency index is 1.4142. This method succeeds in finding the expected nearly root with a known initial value, while the comparison method fails to find the nearly root even with the same converg…
This research was motivated by the loss of learning (loss of learning) during the Covid 19 pandemic. The loss of learning was due to the lack of optimal learning processes carried out in class so that students' skills decreased, including reasoning skills and mathematical proof. The need for teacher creativity to plan learning so that the quality of education increases, especially in the transf…
This research is motivated by the low critical thinking skills of students and the minimal availability of merdeka curriculum-based mathematics assessment instruments. This study aims to produce a merdeka curriculum-based assessment instrument to measure the critical thinking skills of phase E students on sequences and series material that is valid, reliable, has a level of difficulty and good …
