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.

Abstract

This study aims to analyze the structure and meaning of the main poles in traditional houses of the community in Kampung Karekamangeda, Sumba Barat Daya Regency, East Nusa Tenggara Province. The analysis focuses on the selection of pole materials, types and positions of the main poles and supporting posts, as well as their symbolic and functional significance in the context of Sumbanese traditional architecture. Based on literature review and field observations, Sumbanese traditional houses are generally supported by four primary poles symbolizing the family entities (father-mother-son-daughter) along with several other supporting posts that sustain the wall and roof. The use of selected hard wood and the stilt house structure are also characteristic features. The analysis indicates that the main poles not only bear the structural load of the towering roof (the “tower” form) but also serve as cosmological and social status symbols among the Sumba community. Further, the study found that the selection of material, layout and maintenance of the main poles are influenced by living customary beliefs, such as the kinship system and the Marapu belief system.

Abstract

This study aims to explore the mathematical elements embedded in traditional woven mats (tikaradat) from Loura District, Southwest Sumba Regency. These mats, known as nopo or pandan mats, represent an important part of Sumbanese cultural heritage with deep social and aesthetic significance. Using an ethnomathematical approach, this research identifies mathematical concepts present in the form, pattern, and production process of traditional mats. Data were obtained through literature review, observation of local crafts, and hypothetical analysis based on geometric characteristics of mat weaving. The findings reveal the presence of geometry, repetition patterns, symmetry, proportion, and geometric transformations within the structure and motifs of traditional mats. These results indicate that Sumbanese traditional mats can serve as contextual mathematics learning media linking cultural knowledge with formal mathematical concepts

Abstract

This study aims to identify and describe the ethnomathematical elements found in the bedug, a traditional musical instrument used by the community in Loura Subdistrict, Southwest Sumba Regency. The bedug not only functions as a musical instrument, but also has historical, philosophical, and visual value that reflects the cultural practices of the local community. This study uses a qualitative approach with a descriptive ethnographic research type. Data were collected through direct observation, interviews with traditional leaders and local communities, and documentation of the shape and structure of the bedug. The results show that the bedug contains various mathematical concepts, particularly the concept of spatial geometry, such as circles and cylinders, which are evident in the shape of the base and body of the bedug. These findings indicate that the Sumba community has intuitively applied mathematical principles in cultural practices and the creation of traditional artefacts. This study contributes to the development of ethnomathematics-based mathematics learning by integrating local wisdom, thereby making learning more contextual, relevant, and meaningful for students.

Abstract

This study was motivated by the importance of utilising local culture as a context for mathematics learning through an ethnomathematics approach. One cultural artefact that is still used by the people of East Nusa Tenggara is the padalu, or traditional water jar. This study aims to identify and analyse the mathematical elements contained in the padalu as a potential source of contextual mathematics learning. The research method used was descriptive qualitative with data collection techniques in the form of direct observation of the shape of the padalu, measurement of its parts, and visual documentation. Data analysis was carried out by linking the results of observations and measurements with relevant mathematical concepts. The results showed that the padalu represents a combination of a cylindrical shape and a hemisphere. It contains geometric and measurement concepts, such as radius, diameter, height, surface area, volume, symmetry, and size comparison. These findings indicate that padalu has strong potential to be used as a medium for contextual and meaningful local culture-based mathematics learning. Thus, the integration of padalu in mathematics learning can help students understand abstract concepts through real experiences that are close to their daily lives.

Abstract

This study aims to analyse the role of teachers in shaping the discipline and manners of fourth-grade students at Kandelu Kutura State Primary School, as well as to identify the characteristics of students and the factors that hinder their development. The study uses a qualitative approach with observation, interviews, and documentation methods. The research subjects consisted of 20 fourth-grade students and one homeroom teacher. The research was conducted at Kandelu Kutura State Elementary School, West Wewewa District, on 6–8 August 2025. Data were collected through observation of learning activities, in-depth interviews with teachers, and supporting documentation, then analysed using qualitative descriptive analysis. The results showed that the role of teachers in shaping discipline and manners was carried out through setting an example, habit formation, enforcement of rules, and giving advice. However, the students' discipline and manners have not developed optimally, as evidenced by tardiness, late submission of assignments, lack of neatness in dress, and low use of polite language and mutual respect. The main inhibiting factors include students' habits outside of school, lack of parental supervision, and consistency in enforcing rules
