Salah satu jenis keterampilan matematika adalah Kemampuan Pemecahan Masalah Matematis (KPMM). KPMM merupakan kemampuan matematika dengan mengaitkan cara berpikir dalam memecahkan suatu persoalan dengan menggunakan langkah-langkah pemecahan masalah dengan tepat dan sistematis. Indikator KPMM yang digunakan dalam penelitian ini yaitu mengidentifikasi kecukupan data untuk pemecahan masalah, membua…
A complex centrosymmetric diagonal matrix is a diagonal matrix that shows symmetry about its center with its entries in the form of complex numbers. This final project presents the general form of a complex diagonal centrosymmetric matrix raised to an integer power of n, proven using the method of strong induction and a matrix diagonalization. Next, the general formulas for trace, eigenvalues, …

Mathematical communication skills are one of the most important skills that students have in learning mathematics. Learning that facilitates mathematical communication skills can build students' knowledge and understanding of mathematical concepts. There are three indicators of mathematical communication skills, namely, writing, drawing and expression. Solving mathematical problems requires ind…
This research is motivated by the importance of critical thinking skills as an ability to be mastered in the 21st century. The results of PISA 2022 show that only 9% of Indonesian students have reached levels 5 and 6, which means that at this level of ability students can think critically. One of the causes of students' low critical thinking skills is teachers' lack of knowledge in creating tes…
The development of triangular fuzzy numbers is pentagonal fuzzy number. Various alternatives have been presented by outhors regarding the aritmetic of pentagonal fuzzy numbers. Including arithmetic addition, substraction, scalar multiplication, division and also inverse. Particularly for addition, substraction and scalar multiplication there is no enormous diverse. However, for arithmetic …
This thesis discusses regarding inverse and general inverse for hexagonal fuzzy numbers matrix. In this matter, by changing hexagonal fuzzy numbers ea = (a, b, α1, α2, β1, β2) into parametric form ea(r) = [b2(r), b1(r), b1(r), b2(r)] it defines two center points, which are m1(ea) and m2(ea) for any hexagonal fuzzy ea. Such that the arithmetic forms of multiplication, division and invers…
This research is motivated by the government's decision to implement the Minimum Competency Assessment (AKM) as a replacement for the National Examination (UN) with the aim of preparing students for the 21st century. One of the skills measured in the Minimum Competency Assessment (AKM) is numeracy. The national education report for 2022 shows that the numeracy skills of vocational high school s…
This research was motivated by the low ability of students to solve mathematical problems and the unavailability of formative assessment instruments to measure KPMM due to teachers' lack of ability to develop instruments to train KPMM. So that students' mathematical problem solving abilities can be trained and improved, instruments are needed that can measure students' ability to solve problems…
Problem solving skills are a major part of learning mathematics. The importance of problem solving in the teaching and learning process greatly influences attitudes and approaches to dealing with mathematics problems. Problem solving skills are very important for students because by being able to solve a problem students gain experience, use the knowledge and skills that students already have t…
Kemampuan Pemecahan Masalah Matematis (KPMM) adalah kemampuan yang dimiliki oleh peserta didik dalam menyelesaikan masalah matematis melalui empat indikator: (1) memahami masalah; (2) merencanakan penyelesaian masalah; (3) melaksanakan rencana penyelesaian masalah; dan (4) memeriksa kembali hasil yang diperoleh. Penelitian ini dilatarbelakangi oleh rendahnya KPMM peserta didik kelas X Agrihan 2…

The research applied is Classroom Action Research (PTK) on 38 students of class VII.8 SMPN 8 Pekanbaru as research subjects. The learning tools used consist of AT…
This research is motivated by the importance and low mathematical reasoning skills. Mathematical reasoning skills need to be facilitated by using a supporting learning model, namely the Problem Based Learning model which is applied to a series of learning plans called teaching modules. This study aims to produce a Problem Based Learning-based teaching module on the topic of comparison to facili…
This research aims to develop a Problem-Based Learning (PBL) teaching module to facilitate students' mathematical representation abilities (KRM) in the context of linear equations and inequalities systems. Employing a Research and Development (R&D) approach, the module was created using the 4D model, encompassing the stages of define, design, develop, and disseminate. The define phase identifie…
