This research aimed for 1) analyzing the factors which contributed the ability to solve mathematical problems and (2) identifying the domination of the aforementioned factors. This research was conducted to grade 8 in all state junior high schools in the city of Singaraja, academic year of 2017/2018 with 377 participating students which were taken with stratified cluster random sampling technique. This research method was an quantitative ex-post facto research. The data of this research were taken using story math problem about SPLDV, Pythagoras, Lingkaran and were analyzed with factor analysis. The research has found that the factors which contributed the ability to solve mathematical problem are identify problem (identify), define goal (define), explore possible strategies (explore), act on strategies (act) and look back (look). These five factors could be categorized into two components, namely: analytical ability component which consists of identify problem and define goal , and systematical ability component which consists of explore possible strategies, act on strategies and look back. Furthermore, it was also found that the factors which dominated the ability to solve mathematical problem was executing the act on strategies and followed by explore possible strategies, identify problem, define goal, and look back.

Pembelajaran daring pada masa Pandemic Covid-19 menyebabkan menurunnya kemampuan pemahaman konsep matematika siswa. Pembelajaran yang monoton, kurang bervariatif, sekedar memberikan tugas dan kurang memanfaatkan teknologi menjadi beberapa penyebabnya. Salah satu cara yang dapat digunakan sebagai solusinya adalah menyiapkan media dan mengaitkan materi dengan budaya sehari-hari siswa. Tujuan penelitian ini, mendeskripsikan karakteristik dan kualitas media pembelajaran berbasis Android pada materi bangun ruang sisi datar berorientasi etnomatematika sebagai upaya meningkatkan pemahaman konsep matematika. Jenis penelitian ini adalah penelitian pengembangan dengan prosedur pengembangan Plomp. Hasilnya adalah media yang dikembangkan berkualitas valid, praktis, dan efektif. Dengan karakteristik media pembelajaran (1) Siswa melakukan pemahaman terhadap konsep melalui permasalahan awal dengan etnomatematika budaya Bali. (2) Media pembelajaran memuat permasalahan yang dekat dengan kehidupan siswa. (3) Media pembelajaran memuat nilai-nilai budaya Bali yaitu tipat, kerajinan anyaman bambu, dan bangunan rumah adat Bali (4) Media pembelajaran mudah dan mandiri digunakan siswa, dan (5) Media pembelajaran bersifat interaktif.
