Abstract

Indonesian students' performance still tends to be low in solving mathematical problems. In order to explore this issue, further studies are needed to determine the ability of students to solve mathematical problems in various mathematical materials. Therefore, this study aims to describe students' mathematical problem solving ability on geometric sequence material. Descriptive qualitative method was used to describe three research subjects (students of SMAN 6 Bombana) who each represented high, medium, and low ability levels. Tests and interviews were given to collect data which were then analyzed to find out how students' work and errors in solving mathematical problems. The results showed that based on Polya's problem solving indicators, subjects with high and medium ability could solve the problem well, although subjects with medium ability needed two attempts (changing the solution plan) to get the correct answer. Meanwhile, subjects in the low category could not solve the mathematical problems presented in three attempts. In addition, two student errors were found in the solution process, namely: 1) incorrectly using the concept; and 2) incorrectly determining the ratio of the sequence. This study also found a positive participation of adversity quotient as a good mentality for students in solving mathematical problems.

Abstract

Penelitian ini mengkaji unsur etnomatematika dalam ragam hias Mekongga motif tabere pada rumah adat Tolaki Mekongga yang merupakan warisan budaya masyarakat di Kabupaten Kolaka, Sulawesi Tenggara. Fokus penelitian adalah mengidentifikasi dan menganalisis konsep transformasi geometri yang terkandung dalam motif tradisional tersebut. Melalui pendekatan kualitatif dengan metode etnografi, peneliti melakukan observasi langsung, wawancara, dan dokumentasi visual terhadap replika rumah adat yang menampilkan motif tabere. Analisis data dilakukan dengan mengidentifikasi pola matematis, khususnya transformasi geometri yang meliputi refleksi, translasi, rotasi, dan dilatasi. Hasil penelitian menunjukkan bahwa motif tabere memiliki struktur matematis kompleks yang mengikuti kaidah transformasi geometri. Refleksi simetris ditemukan pada susunan motif vertikal, translasi pada pengulangan pola horizontal, rotasi pada elemen dekoratif pusat, dan dilatasi pada perbedaan ukuran motif. Temuan ini membuktikan adanya keterkaitan antara budaya Mekongga dengan konsep matematika formal, yang dapat dimanfaatkan sebagai konteks pembelajaran matematika berbasis budaya lokal. Implementasi hasil penelitian ini dalam pembelajaran matematika di sekolah berpotensi meningkatkan pemahaman siswa tentang konsep transformasi geometri sekaligus memperkuat identitas budaya lokal. Penelitian ini berkontribusi pada pengembangan etnomatematika sebagai bidang kajian yang menghubungkan matematika dengan konteks sosial-budaya masyarakat Indonesia.

Abstract

This study explores the mathematical concepts embedded in the cultural practices and local wisdom of the Mekongga people in Kolaka and East Kolaka Regencies, Southeast Sulawesi, Indonesia. Guided by an ethnomathematical perspective, the research aims to identify and describe how mathematical reasoning manifests through traditional architecture, art, rituals, and social systems. A qualitative approach with an ethnographic design was employed, involving purposive interviews with cultural informants such as the Deputy King of Mekongga, traditional artists, and Tolea (customary leaders). Data were collected through observation, interviews, documentation, and literature review, then analyzed using the Miles and Huberman interactive model consisting of data reduction, display, and conclusion drawing. The findings reveal that Mekongga culture embodies diverse mathematical ideas: set theory in cultural classification and royal genealogies; geometry and proportion in traditional houses; transformational geometry in woven fabrics and decorative motifs; plane geometry and ratio in the kalo sara symbol; social arithmetic in mahar (dowry) traditions; and alternative numeral systems in historical records. These results confirm that mathematical thought is inherently present within local wisdom and daily life. Theoretically, this study strengthens D’Ambrosio’s framework of ethnomathematics by demonstrating how indigenous practices represent mathematical reasoning. Pedagogically, it highlights the potential of Mekongga cultural elements as contextual and meaningful learning resources, bridging abstract mathematical concepts with cultural understanding in mathematics education.

Abstract

Program Pengenalan Lapangan Persekolahan (PLP) merupakan wadah bagi mahasiswa untuk mengaplikasikan kompetensi keguruan secara langsung di lingkungan sekolah. Kegiatan pengabdian ini bertujuan untuk mendeskripsikan implementasi program PLP dalam mendukung kualitas pembelajaran di SMAN 1 Tanggetada. Permasalahan utama yang dihadapi mitra meliputi padatnya jadwal mengajar guru pamong serta keterbatasan infrastruktur pendukung pembelajaran, khususnya akses internet dan pasokan listrik yang belum optimal. Kegiatan dilaksanakan melalui pendekatan partisipatif dan pendampingan langsung selama 36 hari dengan melibatkan tujuh mahasiswa Universitas Sembilanbelas November Kolaka dari berbagai program studi kependidikan. Data kegiatan diperoleh melalui observasi partisipatif, dokumentasi lapangan, dan wawancara dengan kepala sekolah serta guru pamong. Hasil kegiatan menunjukkan bahwa kehadiran mahasiswa PLP memberikan dukungan terhadap proses pembelajaran melalui penerapan metode pembelajaran aktif, pendampingan kegiatan akademik, serta bantuan dalam pelaksanaan tugas administrasi pembelajaran. Berdasarkan hasil observasi dan wawancara, siswa menunjukkan antusiasme dan keterlibatan yang lebih baik selama proses pembelajaran, sementara guru pamong dan pihak sekolah merasakan manfaat berupa dukungan dalam pengelolaan kegiatan pembelajaran. Keterbatasan akses internet disiasati melalui optimalisasi metode pembelajaran interaktif secara luring. Kegiatan ini memberikan kontribusi positif terhadap ekosistem pembelajaran di sekolah serta mendukung upaya pencapaian Tujuan Pembangunan Berkelanjutan (SDGs) bidang pendidikan. Implementation of the PLP Program in Supporting the Improvement of Learning Quality at SMAN 1 Tanggetada Abstract The School Field Introduction Program (Pengenalan Lapangan Persekolahan/PLP) serves as a platform for university students to apply their teaching competencies directly in school settings. This community service activity aimed to describe the implementation of the PLP program in supporting learning quality at SMAN 1 Tanggetada. The partner school's main challenges included the heavy teaching workload of mentor teachers and limitations in educational infrastructure, particularly internet access and electricity supply, which constrained the implementation of technology-based learning. The program was conducted through a participatory approach and direct mentoring over a period of 36 days, involving seven students from Universitas Sembilanbelas November Kolaka representing various teacher education programs. Data were collected through participatory observation, field documentation, and interviews with the school principal and mentor teachers. The findings indicate that the presence of PLP students contributed to the learning process through the implementation of active learning strategies, academic assistance, and support for instructional administration. Based on observations and interview results, students demonstrated improved engagement and participation during classroom activities, while teachers and school administrators perceived benefits in managing learning activities. Limited internet access was addressed through the optimization of face-to-face interactive learning methods. Overall, the program contributed positively to the school's learning ecosystem and supported the achievement of Sustainable Development Goals (SDGs) in the field of education.
