Introduction
Mathematics plays a significant role in everyday life, with nearly all aspects around us being closely related to mathematics, including in the context of cultural society. The connection between mathematics and daily life as well as cultural traditions is very strong (Rewatus et al., 2020). Cultural elements can be introduced in the mathematics learning process at school by linking local knowledge from a specific region to the subject matter being taught (Ayni & Fitraini, 2023). However, in reality, learning that utilizes students’ surrounding environment as a component of instructional materials is still rarely found (Luthfi & Rakhmawati, 2022). One form of mathematics learning that relates to culture is ethnomathematics. Ethnomathematics is an approach in mathematics education that is closely tied to cultural contexts (Mahlina & Suryaningsih, 2022).
In 1977, D'Ambrosio, a mathematician from Brazil, introduced the concept of ethnomathematics. Etymologically, ethnomathematics is derived from three Greek root words: "ethno," referring to natural or sociocultural groups; "mathema," meaning to explain and to learn; and "thic," which refers to ways, arts, and techniques (Mas Rura et al., 2022). Ethnomathematics involves the integration of mathematical concepts and applications from culture into the domain of formal mathematics (Yustinaningrum, 2024). It represents an approach, style, and technique used to explain, understand, and interact with the natural and cultural environment across diverse cultural systems. Research on ethnomathematics in the context of mathematics education can encompass all areas. Ethnomathematics broadly applies mathematical concepts to various activities, such as classification, calculation, measurement, construction of buildings or tools, games, location determination, and more (Astuti et al., 2021). By applying ethnomathematics, mathematics learning is expected to become more enjoyable and innovative, emphasizing contextual understanding derived from students’ own experiences. In addition to increasing student engagement, ethnomathematics also serves as a bridge between education and culture, thereby enriching the cultural values possessed by students (Ethnomathematics, 2020).
Instructional materials are essential elements in supporting and achieving learning objectives in the classroom. These materials play a significant role in the mathematics teaching process, helping students discover the concepts being taught both individually and in groups. Therefore, teachers greatly rely on instructional materials to conduct learning activities effectively (Hisni et al., 2022). One such instructional material that can facilitate the integration of ethnomathematics and the discovery of concepts in the subject matter is the student worksheet (LKPD).
Student Worksheets (LKPD) are learning materials printed in the form of sheets that contain summaries, content, instructions, and assignments completed by students in accordance with the basic competencies (KD) that need to be achieved (Maghfiroh & Suryani, 2023). In general, LKPD includes practicum instructions, experiments that can be done at home, discussion materials, as well as exercises and other guidelines that encourage students to be active in the learning process (Noprinda & Soleh, 2019). Moreover, LKPD also supports teachers in achieving learning objectives in the classroom. Although LKPD is used in the learning process, the teacher's role remains essential and irreplaceable. Teachers act as facilitators and are responsible for monitoring student activities throughout the learning process (Maretha & Suparman, 2022).
Three-dimensional shapes with flat surfaces fall under the categories of geometry and measurement, which are part of the more abstract branches of mathematics (Oktarina, Luhfiana & Refianti, 2019). To facilitate understanding of this concept, mathematics learning methods must provide space for critical thinking and establish a bridge between teachers and students. One necessary approach is to use teaching materials that connect mathematical concepts to students’ cultural backgrounds, making the material more relevant to their daily lives. Additionally, the teaching materials should encourage students to develop concepts independently by discovering them on their own. As a result, learning becomes more meaningful because students experience the process of concept discovery through their own learning experiences, guided by the teacher.
Based on the issues related to ethnomathematics and instructional media previously described, the researcher is interested in exploring the use of ethnomathematics in learning media and assessing students’ responses to it. In addition, the researcher aims to examine the extent to which the development of instructional media can be expanded and implemented within the educational setting at the school level.
Methodology
This study employs the Systematic Literature Review (SLR) method. According to Putra & Afrilia (2020), SLR involves discovering, studying, evaluating, and interpreting previous research. This method allows researchers to review and identify journals at each stage according to the predetermined procedures. Figure 1 below illustrates the SLR research process.

12	Title: Development of Ethnomathematics-Based LKPD on Plane Geometry Material Using Batik Tanjung Bersinar, a Cultural Heritage of Tabalong
Authors: Marfera, Elsa Fajriah; Noor Noorbaiti; Rahmita
Year: 2022	Jurmadikta (Jurnal Mahasiswa Pendidikan Matematika) Volume 2 Nomor 3, Halaman 94-102, November 2022
	The review results of the journal indicate that the ethnomathematics-based LKPD can enhance student engagement in learning and enrich their educational experience through the application of local culture. Overall, the impact of this research makes a significant contribution to the development of culturally-based approaches in mathematics education and can serve as an inspiration for other educators and researchers to creatively and effectively integrate cultural aspects into mathematics learning.	

Based on the review of the 12 articles that met the inclusion and exclusion criteria as detailed in the table above, it can be concluded that the use of ethnomathematics-based learning can enhance students' understanding of mathematics. Ethnomathematics is defined as specific methods used by particular cultural groups or communities in mathematical activities (Sisi ep mbr., 2018). These mathematical activities involve the process of abstracting real-life experiences into mathematical concepts, or vice versa (Yani, Friansah & Yanto, 2023). Such activities include classification, calculation, measurement, designing buildings or tools, creating patterns, estimation, determining locations, games, explanation, and more (Delviana et al., 2019).
Ethnomathematics can serve as an alternative approach for teachers to facilitate students' understanding of mathematics (Fitriana, Putra & Murtinasari, 2024). By utilizing ethnomathematics, students are expected to further develop their metacognitive skills, critical thinking, and problem-solving abilities, particularly in topics such as three-dimensional shapes with flat surfaces (Aulia Ct, 2024). Based on this, the use of student worksheets (LKPD) can support students' mastery in understanding the material (Norhaliza, Nurmeidina & Djamilah, 2022).

Conclusion 
Ethnomathematics-based LKPD can enhance students’ understanding of three-dimensional shapes with flat surfaces. By incorporating ethnomathematical concepts drawn from local culture or cultural heritage sites, the LKPD becomes more contextual and meaningful for students. The developed ethnomathematics-based LKPD demonstrated good validity and practicality based on expert evaluations. It was also found to be effective in improving students’ learning outcomes. Ethnomathematics can serve as an alternative approach for teachers in the learning process to facilitate students’ comprehension of mathematical concepts.
