Learning mathematics at the junior high school level is often considered difficult and uninteresting because the material rarely relates to everyday life. This study explores the concept of ethnomathematics in traditional apem cakes as a source of contextualised teaching materials in mathematics. A descriptive, qualitative method was employed, utilizing observation, documentation, and interviews with two informants who were knowledgeable about the history and preparation of apem cakes to collect data. The results showed that apem cakes have geometric shapes, such as circles and cones, which can be used to teach geometric concepts, including area, circumference, and volume, as well as calculations and ingredient comparisons. Additionally, the cultural significance of apem cakes can enrich the learning experience and boost student engagement. The study concludes that apem cakes have the potential to serve as a meaningful and contextual learning medium. Practically, teachers can design lesson plans utilising apem cake-based calculation examples to make learning more active and relevant for students. However, this study is limited to two informants and has not yet been tested in the classroom, so the results remain descriptive. Further research is recommended to develop student worksheets based on apem cakes and test their effectiveness with junior high school students.

The implementation of mathematics learning in class X of SMK As-Salam revealed that students have difficulty in understanding mathematical concepts because learning methods are predominantly conventional and lack the connection of material to real life. Therefore, an e-LKPD based on live worksheets with contextual problems was developed. This study focuses on testing the validity, practicality, and effectiveness of the e-LKPD based on Liveworksheets. This study aims to develop a contextual e-LKPD based on live worksheets to increase the learning motivation of mathematics students in class X at SMK As-Salam. The research method used is the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model. The developed e-LKPD was validated by experts and tested for practicality through teacher and student responses. The validation results showed that the e-LKPD fell into the highly valid category with a score of 3.668. The product's effectiveness was tested using a paired sample t-test. Based on the analysis of data from 31 students, the average learning motivation score was 51% before treatment and 66% after treatment. The calculated t-value was -3.655, indicating that the e-LKPD is effective, and the sig. (2-tailed) value was 0.000, which is less than 0.05. Therefore, there was a significant increase in student learning motivation after using the e-LKPD. The conclusion of this study shows that contextualized e-LKPD based on live worksheets is effective in increasing students' motivation to learn exponent material. Therefore, it is expected that this e-LKPD can be used as an alternative to innovative learning media to improve the quality of mathematics learning.

This study aims to describe the profile of mathematical representation ability of seventh grade students in solving data presentation problems at Sultan Agung Islamic Junior High School Sudimoro, Malang Regency. This research used descriptive qualitative method involving seventh grade students in the 2024/2025 academic year. Data were collected through written test instruments that included indicators of verbal, symbol, and image representation abilities. The research subjects consisted of 3 students who represented each category of mathematical ability, namely high, medium and low. The results showed that students' verbal and symbol representation skills were very good, reaching a percentage of 91% and 86% respectively. However, the ability of image representation is still lacking because it only reaches a percentage of 45%. Difficulties in image representation are caused by limited understanding of the importance of visual representation in mathematics. students with high mathematical ability can fulfill all indicators of representation ability, namely verbal representation, symbols and images according to their abilities. Students with medium ability can only fulfill two indicators of representation ability, namely symbol and image representation according to their abilities. Students with low mathematical ability have not been able to fulfill all indicators of mathematical representation ability. This study suggests the need for additional practice and teaching to improve students' image representation skills in presenting and analyzing data effectively.

The objective of this study is to describe students' errors in solving word problems related to the Three-Variable Linear Equation System based on Polya's procedure. The errors identified correspond to various stages of Polya's problem-solving method. This research adopts a descriptive approach with qualitative methods. Data collection involved tests and interviews, with the subjects being 10th-grade students at MA Miftahul Ulum Gondanglegi, East Java, Indonesia. The data analysis technique employed data reduction, presentation, and conclusion drawing. The research findings revealed that there are four main types of errors made by students. The most frequent error, accounting for 42%, was in rechecking the solutions obtained, indicating a tendency among students to be less thorough in reviewing their answers. Conversely, the least frequent error, occurring at 8%, was in understanding the problems, suggesting that students generally have a good grasp of what is known and what is asked in the problem. Several factors contribute to these errors, including students' lack of caution in reading and understanding the problems, inaccuracies in performing calculations, a lack of habit in writing down solutions in a sequential and systematic manner, and insufficient practice in verifying their answers.
