The motifs of traditional woven fabric have not been developed by teachers to discuss the link between mathematics and local wisdom. The purpose of this research is to define and describe the mathematical concept of the motifs woven fabric to the students of primary and junior high schools. For the Kefamenanu community, the motif serves as the identity of the person who wears it. Nevertheless, the woven fabric must be present at cultural occasions, welcoming guests, and death ceremonies. The present study uses a descriptive qualitative method to explain the geometry concept on the motifs of woven fabric. The ethnographic approach is also employed as an empirical and theoretical approach to provide description and analysis about a culture based on intensive field work. The results show the geometry concept of the motifs of woven fabric, such as reflection, rotation, translation, repetition,Â triangle and quadrilateral. The motifs of woven fabric owned by the Kefamenanu community contain particular local wisdom and are potentially used to convey the geometry concept in mathematics for primary and junior high schools.

Pada hakekatnya matematika merupakan ilmu pengetahuan yang digunakan untuk menyelesaikan masalah sehari â€“ hari, sedangkan budaya merupakan pola hidup yang terdapat dalam masyarakat yang diwariskan secara turun â€“ temurun. Keterkaitan antara matematika dan budaya dikenal dengan istilah etnomatematika. Etnomatematika merupakan matematika tumbuh dan berkembang dalam budaya. Dengan menerapkannya etnomatematika sebagai suatu pendekatan pembelajaran akan sangat memungkinkan siswa untuk lebih paham dengan materi yang diajarkan. Oleh karena itu penelitian ini bertujuan untuk menganalisis etnomatematika yang terkandung dalam acara adat thelas keta pada masyarakat Noemuti. Teknik pengumpulan data dalam penelitian ini dilakukan dengan observasi, wawancara dan dokumentasi. Teknik analisis data dilakukan dengan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian ini menunjukan bahwa dalam acara adat thelas keta terdapat beberapa konsep matematika antara lain : konsep garis, konsep bangun datar lingkaran, dan konsep bangun datar belah ketupat, konsep bangun datar persegi panjang. Dengan demikian peneliti merekomendasikan agar guru mengembangkan pembelajaran berbasis budaya dalam hal ini berbasis acara adat thelas keta pada materi konsep garis, konsep bangun datar lingkaran, dan konsep bangun datar belah ketupat dan konsep bangun datar persegi panjang. Tujuannya adalah untuk menjembatani matematika dengan budaya lokal sebagai salah satu sumber pembelajaran yang konkret sehingga siswa terlibat aktif dalam kegiatan belajar mengajar.

The linkage of technology in the world of education today has developed rapidly. One of them is the development of mathematics learning media in the form of educational games. The purpose of this research is to develop an educational learning media game that is integrated into Timor local wisdom so that this media has its uniqueness to help students learn. Research on a fast educational game on mathematics based on an android smartphone was conducted at MTs Nurul Falah, Kefamenanu, NTT. The media was developed using software construct 2. The method used in this research is development research with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The results of the validity test based on material experts, media experts, and teachers indicate that educational games with the theme of local wisdom as android-based mathematics learning media were included in the category of very feasible to use with an average validation of 4.33 and very feasible criteria. At this stage, a limited trial using a questionnaire showed that game education received a positive response to the use of game education media with an average percentage of 98.93%. These results indicate that the process of learning mathematics using this media can motivate and facilitate student learning compared to the learning that has been done. During the pandemic, COVID-19 media can be used as online-based learning media because students can easily download the application then the teacher controls the process.

Penelitian ini bertujuan untuk mengetahui keefektifan Pembelajaran Matematika Realistik (PMR) ditinjau dari kemampuan pemecahan masalah siswa kelas VII SMP. Jenis penelitian yang digunakan adalah penelitian eksperimen semu (quasi eksperiment). Teknik pengumpulan data dengan menggunakan metode observasi dan metode tes. Data hasil penelitian dianalisis menggunakan uji Z kolmogorov-Smirnov dengan bantuan SPSS. Hasil penelitian menunjukan bahwa ada keefektifan pendekatan pembelajaran matematika realistik ditinjau dari kemampuan pemecahan masalah matematika siswa SMP. Berdasarkan tabel output â€œGroup Statisticsâ€ diketahui jumlah data kemampuan pemecahan masalah kelas eksperimen adalah 15 siswa dalam kelas control dan 15 siswa yang dilakukan secara konvensional. Nilai rata-rata kemampuan pemecahan masalah matematika siswa untuk kelompok eksperimen adalah 78,27 dan kelompok kontrol adalah 70,07. Penafsiran tabel output Independent Samples Test berpedoman pada nilai yang terdapat dalam tabel â€œEqual variances assusmedâ€. Berdasarkan tabel output â€œIndependent Samples Testâ€ pada bagian â€œEqual variances assumedâ€ diketahui nilai Sig. (2-tailed) sebesar 0,01 < 0,05, maka sebagaimana dasar pengambilan keputusan dalam uji independent sample t test dapat disimpulkan bahwa Ho ditolak dan Ha diterima. Dengan demikian dapat disimpulkan bahwa pendekatan Pembelajaran Matematika Realistik (PMR) lebih efektif ditinjau dari kemampuan pemecahan masalah matematika siswa SMP
