Abstract

The wedding process in Sidareja village, Sidareja District, Cilacap Regency is carried out using a unique and rich traditional ceremony with a meaning that is still thick with Javanese customs. However, this culture is still not widely used to strengthen learning, especially in mathematics learning, so by using ethnomathematical studies, it is hoped that it can clarify the study of the traditional culture of marriage in Sidareja village to be used in learning at school. The purpose of this study is to explore mathematical objects contained in wedding customs in Sidareja Village, Cilacap Regency, Central Java Province. The method used in this study is a descriptive qualitative method. The data collection technique in this study uses documentation, interviews, and observations. This research was carried out by exploring the sources of activities around traditional wedding ceremonies in Sidareja starting from: Preparation, Premarital Ceremony to Panggih Ceremony. The mathematical aspects that are explored include how Preparation (determining the wedding day) is included in the measurement material starting from counting in the concept of division, addition, and numbering. In addition, it was also presented a study of learning about flat figures, namely with the form of flat shapes such as rectangles, parallelograms, triangles, in terms of many, and rhombus found in majang tarub, sindur cloth, chitak, paes, keris-kerisan, kuluk, and suweng which are used in traditional wedding ceremonies in Sidareja village, Cilacap Regency, Central Java Province

Abstract

Purpose—Mathematics learning often remains abstract and disconnected from students’ cultural experiences, which limits creativity and engagement. This study addresses that gap by integrating ethnomathematical content into digital comic media to strengthen students’ self-efficacy and divergent thinking skills.Methodology—A quasi-experimental design using a pretest–posttest control group was employed. The population consisted of seventh-grade junior high school students, and the sample included two classes (N = 52) selected through cluster random sampling. Each class comprised 26 students, with one designated as the experimental group and the other as the control group. The experimental group received instruction using ethnomathematics-based e-comics, while the control group used PowerPoint. Instruments included a self-efficacy questionnaire and a divergent thinking test. Data were analyzed using descriptive statistics and a one-way MANCOVA.Findings—The MANCOVA results showed a significant effect of ethnomathematical e-comic media on both self-efficacy and divergent thinking (Wilks’ Lambda = 0.152, F (2,47) = 131.381, p < 0.05, η² = 0.848). Self-efficacy indicators such as persistence and task commitment improved significantly, while divergent thinking indicators, fluency and flexibility, also increased markedly between pretest and posttest.Contribution—Theoretically, this study contributes to mathematics education by integrating ethnomathematics and digital learning media to support creativity-related skills. Practically, it provides teachers with innovative tools to make geometry learning more engaging and culturally relevant for students in the digital era.
