Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengolah susu segar yang kurang berkualitas menjadi permen susu. Pengolahan ini dimaksudkan untuk meningkatkan nilai jual dan masa simpan susu yang tidak diterima oleh tempat penampungan. Peserta kegiatan adalah kelompok peternak sapi perah “Sri Rejeki” di Dusun Blendongan, Desa Sidoluhur, Kabupaten Malang. Kegiatan dilakukan melalui pendampingan pengolahan susu segar menjadi adonan permen dan pengemasan permen hingga siap jual. Permen yang dihasilkan mempunyai rasa yang enak tetapi kurang rapi dalam pengemasan. Para peserta kegiatan sangat antusias dan mudah memahami cara pembuatan permen susu. Pengembangan produk permen susu terkendala kurangnya peralatan, belum ada merek, belum memahami manajemen keuangan, dan manajemen pemasaran, Karena itu, kegiatan ini akan ditindaklanjuti dengan pelatihan dan pendampingan.

Abstract

This study investigates the impact of the Two Stay Two Stray (TSTS) cooperative learning model on enhancing student achievement and engagement in mathematics education at SMPN 5 Welak, Manggarai Barat, Nusa Tenggara Timur. The research employs a Classroom Action Research (CAR) design, comprising two cycles of implementation. Cycle 1 revealed that 62.69% of students met the minimum competency level, while Cycle 2 demonstrated a significant improvement, with 82.76% achieving the target. Observational data indicated increased student participation and enthusiasm during group discussions, suggesting enhanced engagement. The peer exchange component of the TSTS model facilitated knowledge transfer and reinforced mathematical communication skills. However, challenges persisted for some students in independent problem-solving tasks, indicating the need for additional scaffolding. The findings underscore the effectiveness of the TSTS model in fostering collaborative learning environments that promote academic achievement and active participation. This research contributes to the body of knowledge on cooperative learning strategies in mathematics education and offers insights for educators seeking to implement interactive teaching methods. Future studies could explore the long-term effects of TSTS on student learning outcomes and its applicability across diverse educational settings

Abstract

This study aims to explore the geometric concepts contained in Papuan cultural heritage and integrate them into mathematics learning. The main focus of this study is on three Papuan cultural heritages, namely the Honai traditional house, the Papuan Crown, and the Tifa. These three cultural artifacts not only have deep cultural value but also contain geometric principles that are relevant to mathematics learning. The method used in this study is qualitative research with an ethnographic approach, which involves direct observation and documentation. The data obtained is then analyzed using GeoGebra software to visualize and analyze the geometric shapes in the cultural heritage. The results of the study show that each Papuan cultural heritage contains geometric principles that can be used as examples in mathematics learning, as well as contributing to the development of ethnomathematics learning. The Honai Traditional House, with its circular base, tubular body, and conical roof, reflects the application of stable and efficient geometry. The Papuan crown, with a semicircular base and decorations that contain the principles of rotation, reflection, and dilation, demonstrates the application of symmetrical and harmonious geometry. The Tifa, which is cylindrical or tubular in shape with geometric elements in the form of circles at the top and decorations in the form of isosceles triangles, equilateral triangles, and kites, also reflects the application of significant geometric principles. This study recommends further development related to the application of GeoGebra in ethnomathematics learning and the development of ethnomathematics-based e-LKPD that highlights the cultural heritage of Papua. Thus, it is hoped that mathematics learning can become more contextual and relevant to local culture, as well as provide a more interactive and meaningful learning experience for students. Keywords: Ethnomathematics, GeoGebra, Geometry, Papuan Cultural Heritage.
