Based on previous research, an Android-based AR learning media with an ethnomathematical context has been developed. The media was specially developed for vocational students and prospective mathematics teachers in teaching and learning geometry. However, there has been no research on the development of android-based AR learning media using the ethnomathematical context of Yogyakarta, Indonesia, especially for junior high school students. This research is expected to make a new contribution in the field of AR-based learning technology with ethnomathematics for junior high school students. This is development research carried out using the ADDIE model which consists of five categories: analysis, design, development, implementation, and evaluation. The research was conducted in one of the Islamic junior high schools in Yogyakarta. There were 4 expert validators, 4 mathematics teachers, and 18 students involved in this study. The results of the validity test showed that the multimedia developed was regarded as very valid with a material expert score of 0.83 and a media expert score of 0.80. The results of the practicality test revealed that the multimedia was in the practical category with a practicality percentage of 89% based on teacher assessment and 84% based on student assessment. The data analysis which was carried out using one sample t-test obtained a value of t = 9.92 which was higher than the value of t-table = 1.74. Thus, it can be concluded that the multimedia developed in this current research is effective in improving students’ creative thinking skills.

Masa darurat penyebaran COVID-19 menyebabkan adanya kebijakan baru dalam pelaksanaan proses pembelajaran. Proses pembelajaran yang seharusnya dilakukan dengan tatap muka secara langsung harus dirubah menjadi pembelajaran yang dilaksanakan secara daring atau jarak jauh. Pembelajaran daring atau jarak jauh yang terlaksana masih menemui berbagai macam kendala sehingga diperlukan solusi untuk mengurangi kendala yang terjadi. Melihat fenomena demikian maka KKN Tematika Universitas Alma Ata tahun 2021 berusaha memberikan solusi diantaranya dengan mengadakan kegiatan pendampingan bagi siswa saat belajar di rumah. Pelaksanaan kegiatan pendampingan belajar bagi siswa menggunakan metode pendampingan secara langsung atau secara tatap muka dalam kelompok kecil yang berjumlah 5-10 siswa. Bentuk kegiatan yang dilaksanakan berupa pendampingan dalam mengerjakan tugas-tugas sekolah, latihan-latihan soal, serta menjelaskan materi pelajaran di sekolah yang belum dikuasai atau belum dipahami oleh siswa. Setelah proses bimbingan belajar selesai dilaksanakan, maka selanjutnya dilakukan evaluasi kegiatan. Teknik yang digunakan dalam evaluasi kegiatan pendampingan belajar ini adalah alat ukur non tes, yaitu angket. Hasil angket evaluasi pelaksanaan kegiatan menunjukkan bahwa siswa sangat terbantu dan memberikan respon positif terhadap program kegiatan pendampingan belajar di rumah.
