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.

Abstract

The purpose of this study is to identify the types of motifs on woven fabrics originating from the Southwest Sumba region at the Cultural House. This research was conducted through observation and documentation of traditional Sumba woven fabrics available at the Cultural House. Documentation was carried out to obtain several real photos of Sumba woven fabrics at the Cultural House using qualitative research with an exploratory-descriptive approach. Data collection techniques included interviews, observation, and documentation, while data analysis techniques included data reduction, data presentation, and drawing conclusions. The elements contained are geometric patterns. Many motifs are composed of geometric patterns such as straight lines, parallel lines, diamond shapes, and triangles. Sumba woven fabrics are known for motifs rich in philosophical meaning and also containing mathematical elements. These concepts are mainly related to the geometry of flat planes. In Sumba woven cloth, there are patterns called the main pattern and the border pattern. The main pattern is the primary motif that becomes the focus and attention of the weaving being created. The main pattern usually has a larger, more complex design and contains more twists than the other patterns. In addition, there is also the border pattern, which is a motif that frames, surrounds, or sets boundaries for the main pattern. The size and complexity of the border pattern are usually smaller and simpler compared to the main pattern. The border pattern typically consists of lines, dots, or simple geometric shapes.

Abstract

The purpose of this study was to determine the philosophical meaning and mathematical elements contained in the design of the Ede traditional house. This type of research is aqualitative research with an ethnographic approach, namely an empirical and theoretical approach that aims to obtain an in-depth description and analysis of culture based on intensive fieldwork. The subjects of this study were the historians of the Ede traditional house, namely Mrdominggus bulu, and Mr. oktavianus ngongo. Data collection techniques used are observation guidelines and interview guidelines. The mathematical element in the design of the Ede (Uma katoda) traditional house in Umbu Koba village contains geometric elements such as points, lines, and planes. In the Ede traditional house there are also various geometries, namely plane geometry and space geometry. The geometry of the plane includes triangles, trapezoids, and rectangles. While the geometry of space such as blocks and cubes. In the design of the Ede (Uma katoda) traditional house in the form of a stage, it contains the meaning and principle of balance in it. There are three levels such as the first level as a place for animals, the second level as a shelter for humans and the third level as a place to store food. The high meaning of minarets in the Ede traditional house of Umbu Koba village does not indicate social status but is directed at the Creator or a sign of human greatness and position to establish a relationship with God.

Abstract

The purpose of this research is to explore the meaning of the Sumbanese traditional house, not just as a dwelling, but as a cosmological symbol connecting the human world with the ancestors. The pillars are crucial elements that support the structure and serve as the center of ritual orientation. Therefore, the symbolic, structural function, and philosophical value of the pillars (parona) in the traditional house in Manola Village, South Wewewa District, Southwest Sumba Regency are examined. The research method used was qualitative with a descriptive ethnographic approach. Data were collected through field observations, architectural documentation, and in-depth interviews with traditional leaders (rato) and local craftsmen in Manola Village. The analysis focused on identifying the four main pillars (kambaniru) that play distinct roles in the spatial structure of Wewewa culture. The research results show that the exploration of the pillars of the traditional houses of Manola Village reveals a strict division of functions between masculine and feminine aspects, as well as sacred and profane. Structurally, the use of selected local wood materials demonstrates local wisdom in earthquake disaster mitigation. Symbolically, the pillars represent the vertical relationship with the creator (Maroppo-Marapu) and the horizontal relationship between clans. This study concludes that preserving the architectural details of the pillars in Manola Village is crucial in an effort to maintain Sumba's cultural identity amidst the flow of building modernization.
