Tujuan dari penelitian ini adalah untuk mengeksplorasi konsep matematika pada Masjid Cut Meutia dan menjadi media alternatif dalam pembelajaran matematika. Penelitian ini dilakukan di Masjid Cut Meutia yang berlokasi di Kecamatan Menteng, Jakarta Pusat. Subjek dari penelitian ini adalah pengurus Masjid Cut Meutia yang paham mengenai sejarah Masjid Cut Meutia. Pendekatan etnografi dengan tujuh langkah digunakan untuk mengakomodir kebutuhan dalam penelitian etnomatematika ini. Pengumpulan data dilaksanakan melalui pengamatan, wawancara, dan dokumentasi. Identifikasi konsep matematika pada Masjid Cut Mutia dilakukan melalui pengamatan dan pengambilan gambar pada struktur bangunannya. Teknik analisis data dilakukan dengan reduksi data, penyajian data, dan analisis data serta pemaparan. Keabsahan data diperoleh dengan menggunakan jenis triangulasi metode. Penelusuran informasi terkait nilai-nilai sejarah pada Masjid Cut dilakukan melalui wawancara dan pencarian dalam literatur. Hasil penelitian ini menunjukkan bahwa terdapat unsur geometri yaitu persegi, persegi panjang, lingkaran, belah ketupat, jajargenjang, segitiga siku-siku, trapesium, balok, limas segiempat, tabung, dan setengah bola. Temuan penelitian digunakan sebagai produk etnomatematika sehingga menjadi media alternatif dalam pembelajaran matematika. Selain itu, dapat digunakan sebagai contoh bagaimana konsep matematika diterapkan pada kehidupan sehari-hari dan diharapkan dapat bermanfaat bagi pembelajaran kontekstual.
This study aims to examine the effect of NPF, FDR, CAR and GCG on the profitability of Islamic commercial banks. The data used is secondary data in the form of annual financial reports from 10 Islamic Commercial Banks in Indonesia registered with the Financial Services Authority for the 2017-2020 period. The independent variables used are NPF, FDR, CAR, and GCG which are proxied by the board of directors, independent board of commissioners, and sharia supervisory board. While the dependent variable used is return on assets (ROA). Testing this hypothesis uses a path diagram that is processed with WarpPLS version 8.0. The results of this study indicate that the NPF, FDR, CAR and the sharia supervisory board have significant effect on the profitability of Islamic commercial banks, while the independent board of directors and commissioners have no significant effect on the profitability of Islamic commercial banks.
Understanding the physics concept will be easier if the material can be presented in various forms. Quick Response Code (QR-Code) can provide additional material in the form of videos, PPTs, or websites to facilitate the learning of physics concepts. The methods used in this study is research development (Research and Development), Dick and Carey model with the following steps: identify instructional goals, conduct instructional analysis, identify entry behaviors and learner characteristics, write performance objectives, develop criterion-referenced test items, develop instructional strategy, develop and select instructional materials, develop and conduct formative evaluation, revise instruction, develop and conduct summative evaluation. This study produced textbooks equipped with QR-Code for 12th-grade physics in the odd semester to display physics the materials enriched with various forms of media making it easier for students to understand the concepts learned.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
