Abstract

In general, the North Wewewa Wewewa Woven Fabric of Bokuna Village is passed down from the ancestors and followed until now this Woven Fabric has beautiful motifs made based on daily life and also from nature. Ethnomathematics is a bridge between culture and mathematics, ethmomathematics is adapted by cultural groups to see that the culture contains mathematical aspects. This research aims to find out the concept of geometry in Woven Fabrics. The data collected is in the form of documentation, interviews, and observation results. The type of research used in qualitative descriptive is to describe the mathematical elements contained in woven fabrics. Data collection uses observation and interviews. Data analysis is carried out qualitatively with the stages of data reduction, data presentation, and conclusion drawing. The results of the analysis show that Woven Fabrics are sacred crafts that are inherited from ancestors or from generation to generation. In the study, the researcher found several one-dimensional and two-dimensional buildings. The geometric shapes found by the researcher are: rectangular shape on the entire shape of the woven fabric, an equilateral triangle shape on the mamuli motif, an isosceles triangle shape on the flower motif, a bele ketupat shape on the star motif, a rectangular shape on the entire woven fabric, a square shape on the butterfly motif

Abstract

This study aims to find out the difficulties of students in solving PLSV problems using the demonstration method for grade VII students of SMP Negeri 5 Lamboya. This study uses a qualitative approach with a descriptive method. 14 students as subjects to be researched to the extent to which the students can work on one-variable lienar equation problems. The data collection methods used are tests, interviews, and documentation. Data analysis is carried out qualitatively with the stages of data reduction, data presentation, and conclusion drawing. The results of the study showed that there was still a lack of ability of students to solve PLSV questions that answered the questions correctly and incorrectly. The results of the analysis for problems number 1, 2 and 3 were at the stage of difficulty in interpreting mathematical language (59.66%), the stage of difficulty in using data (64.33%), the stage of difficulty in mastering concepts correctly (66.66%), the stage of difficulty in using calculation operations (66.66%), and the stage of difficulty in drawing conclusions (83.33%). The cause of incompetence is that students do not read the questions carefully so that they make mistakes in writing down what is known and what is asked, so that they are less able to solve problems, in a hurry so that others are incomplete.

Abstract

This study aims to improve the learning outcomes of fourth-grade students at SDK Wanno Badu. This type of research is Classroom Action Research (CAR). The subjects of this study are fourth-grade students at SDK Wanno Badu, totaling 17 students, comprising 9 female students and 8 male students. Data were collected through (1) learning outcome tests, observation, and documentation. Data analysis was carried out using descriptive quantitative and qualitative methods. The results of the observation of teacher activities in managing learning for each cycle, taking into account the average achievement, continued to show an increase from cycle I to cycle II. The teacher activity observation score in cycle I was 80.35, which falls into the good category. In cycle II, there was an increase to 98.21, which is in the very good category. The very good achievement in cycle II indicates that the activities in managing learning to improve student learning outcomes using the STAD-type cooperative learning model were highly effective. The observation results on the students also showed an improvement, namely in cycle I the average score reached 76.78 with a good criterion, and in cycle II it increased to 93.74 with an excellent category. From this research, it was found that in cycle I the average percentage score was 71.76% and the classical completeness was 58.82%, and in cycle II the average percentage score was 84.11% and the classical completeness was 88.23%.

Abstract

The purpose of this study is to determine the mathematical elements contained in woven fabrics at the Ori Angu Waingapu Art Studio. This type of research is descriptive qualitative. The subjects in the study were two cloth traders at the Ori Angu Waingapu Art Studio and the object of the research was Ethnomathematics in Woven Fabrics at the Ori Angu Art Studio. The instruments used in this study were observation sheets, interview sheets, field notes and documentation. The research data analyzed were qualitative research data carried out through three simultaneous activity flows, namely data reduction, data presentation, and conclusion drawing. The results of the study were to find mathematical elements in algebraic form, namely the number of images contained in woven fabrics and more using the formula for the area of a rectangle (P) times the width (L) to calculate a collection of images arranged regularly on woven fabrics. So this discovery got two things, namely using algebraic formulas and rectangular area formulas.

Abstract

The objective of this research is to analyze the two-dimensional geometric shapes found in the roof structures of traditional houses in Weeyelo Village, Kabukarudi, Lamboya District, West Sumba Regency, as part of the fulfillment of course requirements in accordance with the title agreed upon with the supervising lecturer. This study was conducted through interviews with several traditional leaders and by means of documentation to obtain authentic data.The traditional Sumbanese house represents a cultural heritage that functions as both a dwelling place for the adherents of the Marapu belief system and as a sacred space (mbara) for worshiping God through the spirits of the ancestors. Thus, the traditional house also serves as a “church” or place of worship for the Marapu community. According to traditional leaders, the traditional house holds a central role in Sumbanese culture and must be preserved as a way to honor the legacy of the ancestors. The traditional hou eis regarded as the “house of God” that unites people in a spiritual space, where they perform rituals and prayers (mbara) in accordance with their faith and belief.From a mathematical perspective, the traditional Sumbanese house contains various geometric elements, such as two-dimensional and three-dimensional shapes, similarity, and congruence. In addition, the houses are decorated with carved ornaments, which are creative cultural expressions passed down through generations and preserved as part of local identity.

Abstract

This study aims to explore and identify mathematical elements found in the historical stone graves located in Bukaregha Village, Loura District, Southwest Sumba Regency. These stone graves are cultural heritage artifacts of the Sumbanese people, possessing significant historical, philosophical, and geometric values. This research uses a descriptive qualitative method with an ethnomathematical approach, focusing on the relationship between local culture and mathematical concepts. Data were collected through field observations, interviews with traditional leaders, and documentation of the stone grave structures. The findings reveal that the structure of the stone graves contains various mathematical elements, such as geometric shapes (squares, rectangles, blocks, and cubes) as well as concepts of length and volume measurement. These results indicate that the Sumbanese community has intuitively applied mathematical principles within their cultural practices and traditional architectural designs. This study is expected to serve as a reference for the development of ethnomathematics-based learning, particularly in integrating mathematics with local wisdom to enhance relevance and meaningful learning for students.
