Melalui penanaman prinsip keadilan dalam setiap proses pembelajaran daring, kerangka yang ditawarkan bertujuan mengarahkan literasi digital pada hasil yang transformatif, sekaligus melestarikan warisan budaya serta melindungi keberlangsungan lebih dari 700 bahasa lokal
Ethnomathematics in Oko Mama Woven Craft of the Amanuban Community: A Geometric Study
No full textMathematics is often perceived as a challenging subject by students, necessitating innovative instructional approaches that enhance conceptual understanding and contextual relevance. The ethnomathematics approach presents a valuable strategy by linking mathematical ideas to cultural practices, thus fostering more meaningful learning. This study focuses on exploring mathematical concepts embedded in the oko mama plaiting craft tradition of the Amanuban community in South Central Timor. Through a qualitative design with an ethnographic method, the research involved direct engagement with three local artisans selected purposively based on their expertise. Data collection was conducted through semi-structured interviews, field observations, and documentation, followed by triangulation to ensure data validity. The analysis uncovered a variety of geometric concepts found in the artisans’ practices. These include two-dimensional shapes such as squares, rectangles, parallelograms, rhombuses, triangles, trapezoids, and both regular and irregular hexagons and three-dimensional forms such as cubes, rectangular prisms, triangular prisms, and hexagonal prisms. Mathematical ideas involving perimeter, area, and volume also emerged through the measurement and structuring techniques used in plaiting. The study demonstrates that local cultural practices serve not only as expressions of heritage but also as rich sources of mathematical thinking. Findings highlight the potential of the oko mama craft to serve as a contextual learning resource for geometry education. This research contributes to the existing body of knowledge by offering a more comprehensive ethnomathematical analysis compared to earlier studies that focused narrowly on basic geometric forms and calculations
Effect of Example-Based Learning Model on Micro Level Cognitive Load and Knowledge Transfer
No full textStudents often face difficulties in solving math problems due to high cognitive load. This load can interfere with optimal information processing, particularly at the micro-level, such as in problem-solving steps. Although many studies have examined cognitive load, most focus on macro-level, with limited exploration of micro-level cognitive processing. To address this, an effective learning approach is needed to optimize students’ working memory capacity and promote knowledge transfer. This study aims to investigate the effect of an example-based learning model on cognitive load and knowledge transfer in mathematics learning. A quasi-experimental method was conducted involving 78 eighth-grade students from a school in Serang City, divided into two groups: an experimental group applying the example-based learning model and a control group using a problem-solving model. Data were collected using a mental effort rating scale and essay questions to measure cognitive load at each problem-solving step, along with retention and near-transfer tests. Analysis using Two-Way ANOVA showed that the example-based learning model significantly reduced cognitive load throughout the problem-solving stages. It also produced better outcomes in retention and near-transfer tests, indicating more effective knowledge transfer. These findings suggest that example-based learning can be a valuable instructional strategy to improve mathematical problem-solving, particularly for students with limited background knowledge. The novelty of this study rests on the simultaneous examination of retention and transfer, focusing on students\u27 micro-level cognitive processing during example-based learning. Structured examples were shown to reduce cognitive burden while fostering transferable problem-solving strategies

Correlation Analysis of Slaughter Weight and Body Dimensions on Bali Cattle Carcass Production Based on Sexes
No full textCarcass production in Bali cattle is an important indicator in the livestock industry, influenced by genetic and environmental factors, particularly live weight and body dimensions. However, studies comparing the contribution of slaughter weight and body dimensions to carcass production based on the sex of Bali cattle remain limited. This study aims to analyze the relationship between slaughter weight and body dimensions with carcass production in male and female Bali cattle in order to provide precise information for slaughter animal selection. The research was conducted using a survey method and direct measurements of slaughter weight, body dimensions (body length, withers height, and chest girth), and carcass production in 30 Bali cattle (15 males and 15 females) slaughtered at the Kendari City Slaughterhouse. Samples were randomly selected from the population of slaughter-ready cattle. The results showed that slaughter weight had a very strong correlation with carcass production in both male (r = 0.99) and female (r = 0.91) Bali cattle. Among all the measured body dimensions, chest girth showed the most significant influence on carcass production. In conclusion, slaughter weight is the main predictor of carcass production, and chest girth can be used as an additional indicator in selecting Bali cattle, regardless of sex. The contribution of this study is to provide deeper insight into the size-related factors affecting carcass productivity by sex, which can be utilized in breeding programs and livestock slaughter management
