Abstract

Ethnomathematics is a science used to study how mathematics originates from a culture. This study aims to explore ethnomathematics in Sumbawa buffalo racing accessories and equipment. This type of research is qualitative with an ethnographic approach. Data sources were obtained from observations, interviews with cultural figures, buffalo racing owners, and sandro or shamans. Data analysis used an ethnographic approach consisting of the following stages: (1) determining informants who have in-depth knowledge, (2) conducting interviews to gather information, (3) making ethnographic notes in the form of written documentation, (4) asking descriptive questions to gain a general overview, (5) analyzing the results of ethnographic interviews to find themes, (6) conducting domain analysis to identify cultural data, (7) asking structural questions to determine the relationships between elements in one domain, (8) conducting taxonomic analysis to group data, (9) writing ethnography based on the researcher's findings, and (10) validation. The results of the study show that: 1) the meanings contained in the accessories and equipment of Sumbawa buffalo racing are courage, peace, fertility, and strength. 2) the mathematical concepts or principles in the accessories and equipment of Sumbawa buffalo racing are two-dimensional geometry (rhombus, circle, trapezoid, and triangle), three-dimensional geometry (cylinder and cone), analytical geometry (hyperbola and hyperboloid) and transformation and regularity geometry (repeating patterns, parallel lines, perpendicular lines, midpoints, and right angles).

Abstract

Based on the initial study, the mathematical problem-solving ability and mathematical disposition of eighth-grade students of SMPN 1 Mataram in the 2024/2025 academic year are classified as low. This study aims to determine the effect of mathematical disposition on mathematical problem-solving ability. The method used is quantitative with a comparative causal type (ex-post facto). The study population was 436 students, and a sample of 78 students was selected through a purposive sampling technique. The instruments used were a mathematical disposition questionnaire and a mathematical problem-solving ability test. The results of the descriptive analysis showed i) most students had high mathematical disposition (39 students); ii) most students had very high mathematical problem-solving ability (29 students); iii) most had high mathematical disposition with very high problem-solving ability (16 students). Based on a simple linear regression analysis, the equation   , was obtained. This means that every 1 increase in mathematical disposition value will cause the mathematical problem-solving ability value to increase by 0.304. Hypothesis testing shows a significant influence between mathematical disposition and mathematical problem-solving ability. The coefficient of determination  value is 0.289, indicating that mathematical disposition contributes 28.9%.

Abstract

This research aims to produce mathematics learning media in the form of Student Worksheets (LKPD) based on the Problem Based Learning (PBL) Model in statistical material oriented towards numeracy skills. The development of worksheets was carried out based on the development model by Plomp. One of the qualities of the media developed includes practical aspects. The practicality of the worksheets learning media was assessed by students by filling out a response questionnaire on the use of worksheets. The developed worksheets meets practical criteria if the average score of students' responses to mathematics learning media is in the minimum good classification (X>28). The response questionnaire for using worksheets was filled in by students in grades 8.4 and 8.5 of MTsN 1 Mataram, totaling 51 students. The research results show that the worksheets meets practical criteria. Based on the results of student responses, students' use of worksheets shows an average score of 32.48 which has a good classification. Thus, the worksheets developed is easy and useful to use in mathematics learning.
