Abstract

This study was conducted to identify the types of difficulties experienced by students in solving PLSV problems. Descriptive type of research using test instruments and interview guidelines. The research location at MTs ar Riyadh Jenggawah Jember in class VII a total of 30 students. Subjects with the identification results of post-test results had difficulty with operations, concepts, and understanding the problem as many as 3 people. The indicators in the study include three parts, namely difficulties in operations, difficulties in concepts, and difficulties in understanding the problem. From the results of the data obtained, 41.5% of students had difficulty operating, 65% had difficulty in mathematical concepts, and 50% had difficulty in understanding the problem. Based on the results of the analysis obtained, the subject has difficulty in determining the result of an operation through the process of subtraction, addition, multiplication, and division (difficulty in operations), the subject has difficulty in classifying and using the appropriate theorems and formulas (difficulty in concepts), and the subject has difficulty in visualizing / describing / rewriting the contents of the problem in the form of a mathematical model (difficulty understanding). The factors that cause difficulties experienced by students are not only from within students but also from teaching staff who only stick to conventional methods and rarely use learning media so that in teaching and learning activities students are less active.

Abstract

Mathematics is often perceived as an abstract discipline, detached from everyday life. However, mathematical concepts can actually be found within local cultures, one example being in the costume of Tari Lahbako, a traditional dance from Jember that represents the life of tobacco workers. This study aims to explore elements of ethnomathematics in the Tari Lahbako costume using a descriptive approach with ethnographic methods. Data were collected through direct observation and in-depth interviews at two dance studios: Sanggar Sweeta Collection and Sanggar Ninien Ariesitta. The results indicate that costume elements such as the hair bun, apron, skirt, and other accessories contain geometric shapes such as squares, circles, rhombuses, trapezoids, as well as concepts of reflection, parallel lines, and right angles. In addition, the presence of symmetrical patterns and regularity in the costume reveals an intuitive mathematical understanding by the designers. Therefore, the Tari Lahbako costume not only holds aesthetic and cultural value but also has great potential to be used as a medium for contextual mathematics learning. Through an ethnomathematical approach, students can understand mathematical concepts more concretely, meaningfully, and rooted in local wisdom

Abstract

Mathematics is often perceived as an abstract science detached from daily life, whereas in reality, it grows and develops within the culture of society. The ethnomathematics approach seeks to reveal how mathematical concept, especially geometry, manifest within cultural practices and architectural works. This study aims to explore the application of geometric concepts in the architecture of Saint Joseph Catholic Church Jember as an integration of mathematics, culture, and spirituality. The research employed a qualitative approach with an ethnographic case study design through participatory observation, interviews, and visual documentation. The result show that various elements of the church building, such as the bell tower, triangular roof, arched windows, pillars, stained glass, and floor mosaics, contain geometric concepts such as plane figures, solid figures, symmetry, similarity, and geometric transformations including reflection, rotation, and translation. Each architectural element demonstrates not only mathematical order but also symbolic meanings such as balance, perfection, and eternity that reflect Catholic faith values. The findings affirm that ethnomathematics serves as a bridge between science, art, and cultural values, making mathematics learning more contextual, meaningful, and grounded in real life.
