Welfare is a measuring point for a society to indicate that it is in a prosperous condition. Even though West Sumatra has businesses in various sectors, in terms of equitable distribution of development, it is still uneven. The success of the development and welfare of an area can be known from the human development index (HDI) and education indicators. The purpose of this study was to identify characteristics based on the mapping results of education and HDI in districts and cities in West Sumatra Province using multidimensional scaling analysis. Based on the results of the mapping, what needs to be considered from the level of education and HDI are the Mentawai Islands Regency, Pasaman Regency, Sijunjung Regency, Solok Regency, Solok Selatan Regency, and Dharmasraya Regency with a significance level of 0,01. The value is 99,79%, so the mapping obtained from the multidimensional scaling analysis is acceptable.

This study aims to reveal the mathematical activities in the construction of Pedati Gede Cirebon and the potential for its integration into mathematics learning through ethnomathematics exploration. This study follows a qualitative research method with a qualitative verification research design to obtain a clear picture of the relationship between the technology used and the mathematical activities. The data collection techniques include observation, interviews, and material review. Based on the data collected and analyzed, it was found that mathematical activities can be seen in several depictions of existing technology, especially in the construction of large wheels. The designer of Pedati Gede Cirebon hopes for a large mechanical advantage for energy efficiency when operating it. This mechanical advantage is closely related to the concept of comparison in junior high school mathematics learning, so it can be used as a context for learning the concept of comparison to make it more meaningful. Several other mathematical concepts in the mathematical activities and construction of Pedati Gede Cirebon are the concept of circles and linear equations. The circle is related to the pillars of the wheel as support, while the concept of linear equations is used in determining certain quantities in several sizes available in the construction of Pedati Gede Cirebon.

Mathematical literacy is a crucial competency for university students, yet research indicates that many students struggle to apply it effectively. This study aims to analyze students' mathematical mindsets in addressing mathematical literacy challenges and their implications for mathematics education in higher education. The research employs a descriptive qualitative design, involving three second-semester students selected through purposive sampling. Data collection methods include observation, in-depth interviews, and analysis of mathematical literacy tests, focusing on indicators such as the ability to formulate mathematical situations, apply mathematical concepts and procedures, and interpret mathematical results. Data analysis was conducted through several stages: data reduction, data presentation, drawing conclusions, identifying students' mindsets in solving mathematical problems, and source triangulation. The findings reveal that students' mathematical thinking is influenced by cognitive development, cognitive style, and problem-solving strategies. While some students successfully solve mathematical literacy problems, they still make errors in several concepts and often exhibit carelessness in reading the questions. This research has significant implications for mathematics education in higher education, including the need to emphasize conceptual understanding, balance procedures, and concepts, and utilize visual representations. The development of teaching materials and mathematical literacy questions should be designed to accommodate diverse student mindsets and be grounded in realistic contexts.
