Abstract

Additionally, resilience to crises makes Islamic banking one of the leading solutions to overcoming the economic crisis. This research aims to analyse the level of performance of Islamic banking in Indonesia and determine factors, including the impact of the COVID-19 pandemic during the 2011-2022 period, using 11 Islamic commercial banks in Indonesia. The analysis method used is DEA Two Stage, with secondary data from the financial reports of each Islamic commercial bank. The input variables are fixed assets, labour costs, and third-party funds. The output variables are the amount of financing provided and operational income. The research results explain that no Islamic commercial banks in Indonesia achieved optimal efficiency during the research period. Then, the efficiency level of Islamic commercial banks in Indonesia fluctuated yearly during the research period. Furthermore, the COVID-19 pandemic has impacted the efficiency level of Islamic commercial banks in Indonesia. In the potential improvement analysis, know that the most significant source of inefficiency is the output variable: the amount of financing provided. The results of the benchmarking analysis found Islamic commercial banks with the most references, where the year most referred to was 2021-2022.

Abstract

Penelitian ini dilatar belakangi oleh kegagalan siswa dalam menyelesaikan soal teorema Phytagoras pada tahap ketiga, keempat dan adanya kesenjangan antara potensi teknologi inovatif dengan praktik pembelajaran yang masih menggunakan metode konvensional. Penelitian ini bertujuan untuk menghasilkan media pembelajaran interaktif dengan Articulate Storyline yang memenuhi kriteria valid, dan praktis dari penggunaan media yang dihasilkan. Metode penelitian menggunakan PPE. Teknik pengumpulan data dilakukan melalui wawancara tidak terstruktur dan angket. Instrumen terdiri dari lembar validasi serta angket respon siswa. Hasil penelitian menunjukkan bahwa media pembelajaran ini memenuhi standar kelayakan yang telah ditetapkan. Hasil uji koefisien kappa menunjukkan bahwa ada kesepakatan yang kuat dengan signifikansi rendah antara kedua kelompok rater. Kesepakatan rater materi memiliki koefisien kappa sebesar 0,625, kesepakatan rater media memiliki koefisien kappa sebesar 0,750. Nilai-nilai ini menunjukkan bahwa kedua kelompok rater telah sepakat secara signifikan dalam menilai kualitas media pembelajaran, dan hasil kesepakatan ini tidak terjadi secara kebetulan. Hasil angket menunjukkan bahwa siswa memberikan penilaian yang sangat baik terhadap kepraktisan media pembelajaran interaktif berbasis Android tersebut dalam penggunaannya. Hasil penelitian ini mengindikasikan bahwa pengembangan media pembelajaran interaktif dengan Articulate Storyline untuk materi teorema Phytagoras telah berhasil memenuhi standar validitas dari rater dan praktis dari siswa.This research is motivated by the failure of students in solving Phytagoras theorem problems in the third, fourth stages and the gap between the potential of innovative technology and learning practices that still use conventional methods. This research aims to produce interactive learning media with Articulate Storyline that meets the criteria of valid, and practical use of the resulting media. The research method uses PPE. Data collection techniques were conducted through unstructured interviews and questionnaires. The instruments consisted of validation sheets and student response questionnaires. The results showed that this learning media met the predetermined eligibility standards. The kappa coefficient test results show that there is a strong agreement with low significance between the two rater groups. The material rater agreement has a kappa coefficient of 0.625, the media rater agreement has a kappa coefficient of 0.750. These values indicate that both groups of raters have agreed significantly in assessing the quality of the learning media, and the results of this agreement did not occur by chance. The questionnaire results showed that students gave a very good assessment of the practicality of the Android-based interactive learning media in use. The results of this study indicate that the development of interactive learning media with Articulate Storyline for Phytagoras theorem material has been successful.

Abstract

This research aims to determine the effect of the metaphorical thinking approach on students' mathematical critical thinking abilities and determine the percentage of students' mathematical critical thinking abilities who use the metaphorical thinking approach. The method used is the experimental method, namely Pretest-Posttest Control Group Design. The population in the study was all students in class VIII of SMP Negeri 1 Tasikmalaya. The samples in the research were students in class VIII G as the experimental class and class VIII A as the control class. The sample technique uses random assignment. The instrument used is a description test of mathematical critical thinking abilities. Data analysis techniques include descriptive statistics and inferential statistics by analyzing and measuring students' mathematical critical thinking skills using IBM SPSS Statistics 24. Normality test using Shapiro Wilk, homogeneity test using Levene's, mean difference test (right side) using Independent Sample T- Test, and the Mann Whitney test. Based on the results of data analysis, it can be concluded that there is an influence of the metaphorical thinking approach on students' mathematical critical thinking abilities. The mathematical critical thinking ability of students with a metaphorical thinking approach is in the high category 40.625%, medium 40.625%, low 18.75%, and the overall average score is 58% in the medium category.
