Angle trisectors are basically for Morley’s Theorem, which is about the exis- tence of equilateral triangles formed from the intersection of trisectors. This angle trisector has been developed by several authors on the convex quadrilate- ral with the result in the form of a comparison of the area of the shape formed from the angle trisector. In addition to area comparisons on angle trisectors…
This research aims to produce LKPD based on the Realistic Mathematics Education Approach (PMR) Circle content to facilitate valid and practical mathematical critical thinking skills of SMP/MTs students. The research method used was research and development (R&D) with a 4-D model (four D models). This research involved 3 validators, in the one to one evaluation trial involving 3 students, in the…
This research is based on the importance of students communicate mathematically ability. The limited ability of students to communicate mathematically in the topic of Circles is due to the learning model used not yet facilitating students' mathematical communication skills. This study aims to produce mathematical learning tools in the form of syllabus, RPP, and LAS using the Reciprocal Teaching…
This research was motivated by the low mathematics learning achievement of class VIII-1 students at SMPN 6 Siak Hulu in the 2023/2024 academic year. The aim of this research is to improve the quality of the learning process and the results of mathematics learning achievement by applying the Problem Based Learning (PBL) model. The subjects of this research consisted of class VIII-1 students at S…
This study is based on the importance of students' mathematical critical thinking ability. Facts show that the level of critical thinking of Indonesian students is still low, especially in the subjects of prism and pyramid. This study aims to produce Student Worksheet (SW) based on Contextual Teaching and Learning for prism and pyramid subjects that is valid and practical to facilitate the math…
Improving the learning process and increasing student mathematics learning outcomes by applying the Problem Based Learning (PBL) model is the main objective of this Classroom Action Research. The research was carried out in two cycles on class VIII Al-Kindy students at SMPIT Al-Andalus Pekanbaru with a total of 26 students. The research instruments used were learning tools (syllabus, RPP and LK…

The subjects of this study were students of class 〖VIII〗…
The development of teaching modules based on Problem Based Learning on the content of data distribution measures for phase E students with valid and practical criteria is the purpose of this research. This research is a development research (R&D) with the 4D model with four stages, namely Define, Design, Development, and Disseminate. The instruments used were validation sheets and learner respo…
The problem with class VIII.2 students at SMPN 17 Pekanbaru is that learning only takes place in one direction. Students are not actively involved in learning, and most importantly students are not able to solve problems using problem solving steps, which causes students' KPMM to be low. Based on the problems described above, an innovative and interesting learning model is needed so that it can…
The mathematical reasoning ability is one of the most important parts of mathematics learning, but the facts show that students’ mathematical reasoning ability is still low, especially in the content of the Pythagorean theorem. One of the attempt to facilitate it is by using students’ worksheet based on Creative Problem Solving (CPS). The aim of this research is to develop valid and practic…
Penelitian ini dilatarbelakangi oleh kemampuan pemecahan masalah matematis (KPMM) peserta didik yang rendah dan keterbatasan perangkat pembelajaran berupa modul ajar sebagai pendukung implementasi kurikulum merdeka. KPMM yang rendah dapat diperbaiki melalui perbaikan pada proses pembelajaran. Salah satu model pembelajaran yang menunjang kreativitas peserta didik dan memfasilitasi KPMM peserta d…
This research was motivated by the low statistical literacy skills of students in class VIII.3 SMP Negeri 42 Pekanbaru which was caused by the teacher-centered learning process. One way that can be used to overcome this is by applying the Problem Based Learning model. This type of research is a classroom action research consisting of two cycles. Each cycle includes planning, implementation, obs…
This research was motivated by the low mathematics learning outcomes of grade VIII MTs Hayatul Islamiyah Pangean students caused by the teacher-centered learning process. One way that can be used to overcome this is by applying the Problem Based Learning model. This type of research is class action research consisting of two cycles. Each cycle includes planning, execution, observation, and refl…
This research aims to produce a valid and practical mathematics module on number pattern materials to facilitate mathematical reasoning abilities. This research uses 4D development model which includes define, design, develop, and disseminate. The subject in this research were junior high school 8th grade students. The forms of data in this research are qualitative and quantitative. Qualitative…
This research was motivated by the low learning outcomes of students in the eleventh grade at IT High School Al-Fityah Pekanbaru. This research was a classroom action research using the Problem Based Learning (PBL) model to improve mathematical learning outcomes and learning processes. It consists of two cycles of action that pass through four stages: planning, implementation, observation, and …
The low ability to solve students' mathematical problems in the Flat-Side Building material is due to the limited learning tools used in mathematics learning according to students' needs. This research aims to produce mathematics learning tools in the form of a syllabus, lesson plans and worksheet using the Problem Based Learning model in the Flat-Side Space Building material for class VIII SMP…
This final project discusses the solution of fractional linear programming using dynamic programming forward methods. The solution to this problem is to find the optimal solution of the fractional linear programing by changing the fractional objective function to an approximation function using the simplified method, followed by using the simplex method until the optimal solution is obtained. T…
Global climate change can lead to extreme weather events that often lead to losses. One of these extreme weather events is the storm rainfall. Therefore, it is necessary to model rainfall that can describe the characteristics of rainfall data as well as predict the same extreme events in the future. The research involves the modeling of storm rainfall, with data obtained using storm analysis…
