Abstract

Education is the heart of the world. Exploration activities demonstrate students' mathematical problem-solving skills. Research purposes; The first, Identification learning outcomes by describing high, medium, and low Self-Regulated Learning (SRL) problem-solving abilities through the Missouri Mathematics Project (MMP). The second is to find out if the MMP model has a role in achieving classical mastery in its ability to solve mathematical problems the average value is it purpose achieved ≥ 80 in 75% of all samples. Mixed method, concurrent embedded design. A total of 75 students of the 8th grade of the SMP Pesantren Attaqwa Bogor in 2022-2023. Data from Problem-solving skills tests, SRL questionnaires, and interviews. Include 6 subjects; two high SRL students, two medium SRL students, and two low SRL students are picked from the 75 SRL-enrolled students. The teacher of the topic to be questioned in this study choose which students to interview. The research results show that: First, Students with high SRL are able to master the 4 components of Polya problem solving; medium SRL students are still able to understand the problem, make a settlement plan, carry out the settlement plan but are less able to re-examine the work; low SRL students are able to understand the problem but are less able to make a settlement plan, carry out the completion plan and re-check the work. Secondly, the KPM of statistical material students in the MMP model exceeded the mastery learning average score of ≥ 80 in 75% of class VIII students.

Abstract

  The decrease in students' mathematical abilities is caused by students' low interest or motivation in mathematics and the use of teaching approaches that are not suitable for students' learning styles, which is decreasing their interest in learning and struggling to understand mathematical materials. This quantitative study with experimental method aims to find out how influential RME (Realistic Mathematics Education) through role play method is on students' mathematical representation ability. A total of 66 students were positioned as research subjects. Data on students' mathematical representation ability was collected using a test of 5 description questions and analyzed using descriptive statistics in the form of averages and analytical statistics in the form of t-test (Independent Sample Test). The results showed a statistically significant difference between the mathematical representation ability of students who applied RME and students who only applied conventional learning. And if there is a difference then there is an effect of the treatment given to the experimental class. Following up on the findings in this study, RME with role-playing method has a positive effect on students' mathematical representation skills and can be applied in learning mathematics considering that it can encourage students to be actively involved and create a new circumstance in learning.

In order to apply the mathematical ideas discovered as a method for teaching mathematics in schools, the study's objective was to investigate the mathematical ideas present in the "Siwaluh Jabu" roof design. Through observation, interviews, documentation, and an ethnographic approach, this study also used a literature review and a descriptive qualitative methodology. The Miles and Huberman method, which entails data reduction, data presentation, and conclusion drawing, is used in the data analysis process. The study's findings revealed the concepts of a flat shape, spatial geometry, and congruence. The results of this study can be used as learning aids and approaches to learning mathematics.

Abstract

The purpose of this study is to describe how students' mathematical literacy is in solving ethnomathematics-based questions in terms of student self-efficacy. Three grade VIII students of SMP Negeri 1 Surakarta were selected as samples based on the results of the self-efficacy questionnaire and assigned according to the self-efficacy category. Data collection techniques were carried out using self-efficacy questionnaires, mathematical literacy tests, and interviews. The results of the research that has been done show that students with high self-efficacy categories can fulfill the six indicators of mathematical literacy. Students in the self-efficacy category are being able to solve the questions given, but have not been able to fulfill the indicators of using arithmetic operations and mathematical symbols. Students in the low self-efficacy category were only able to fulfill the communication and mathematization indicators on the three mathematical literacy questions.

Abstract

The Sipirok woven fabric industry is one of the industrial characteristics of South Tapanuli Regency in North Sumatra. In general, the challenges encountered in the industry are related to production optimization. There have been numerous research on production optimization that use mathematical methods such as the simplex method. However, the simplex technique has limits, as it only has one objective function. As a result, the Fuzzy Multi-Objective Linear Program method is employed in this study. Because Fuzzy Multi-Objective linear program includes two objective functions, maximizing profits and reducing/minimizing processing time, it can be used to tackle optimization issues in the Sipirok woven fabric company. This sort of research employs primary data, specifically interviews and direct observation at the research site, the Sipirok Woven Fabric Industry. This study's calculations were supplemented by the simplex method, which was then followed by the two-phase simplex method to generate the ultimate outcome of woven fabric manufacture. The woven fabric industry now produces 472 units of Samuel's woven fabric, with a maximum profit of Rp. 37,920,000 and a minimum processing time of 7,110 hours, where the variable value λ is 0.10 to represent the maximum degree of each objective function.

Abstract

Mathematics is a basic science that is always related to other sciences. Many people think of mathematics as a science requiring more effort. Ethnomathematics, as a scientific study, can bridge the gap between mathematics, culture, and life. Through ethnomathematics, it becomes easier for students to learn mathematics. This paper involves a mathematical exploration of eceng gondok crafts. Eceng gondok is one of the main ingredients for handicrafts in great demand by people at home and abroad. The primary objective of this research is to explore the mathematical elements in eceng gondok crafts. Teachers and students can use the results of this study as a learning medium to facilitate understanding in learning some mathematical material. This research follows qualitative descriptive research with an ethnographic focus. This study used observation and interviews with one of the eceng gondok craft industry owners in collecting data. Data analysis from this research was conducted inductively through four activities: collecting, reducing, categorizing, and drawing conclusions. The results found that this eceng gondok craft contained many mathematical elements, including geometric concepts, calculus concepts, and a system of linear equations in three variables.
