Abstract

This study aims to model the factors influencing the Sukuk Ratings at Sharia Commercial Banks in Indonesia by examining key financial variables, including Return on Assets, Return on Equity, Firm Size, Stock Profit, and Debt-to-Equity Ratio. Sukuk ratings provide crucial information for potential investors to assess the risk and return of purchasing specific sukuks. A decline in Sukuk ratings, as observed in this research, could reduce investor interest and increase the risk of default. Sukuk levels, issued by authorized rating agencies, are essential for enabling investors to estimate the risks associated with their investments. Using a quantitative approach with panel data from the PEFINDO website covering three Sharia Commercial Banks from 2021 to 2023, this research applies the Common Effect Model for regression analysis. The findings indicate that variables ROA, ROE, Firm Size, and Stock Profit significantly influence Sukuk Ratings, while DER does not. The coefficient of determination (R²) is 0.77895, indicating that these independent variables explain 77.895% of the variance in sukuk ratings. This model provides valuable insights for investors and regulators in understanding the factors affecting sukuk ratings, thereby aiding better decision-making, enhancing investor confidence, and supporting the growth of the Islamic capital market.

Abstract

Indonesia is a country with a Muslim majority. Based on data from Kemendagri, Indonesia's Muslim population is 237.53 million people with a percentage of 86.9% as of December 31, 2021. Indonesia as a country with a Muslim majority means that it must consume and use halal-certified products. The halal industry is currently growing rapidly. Not only in the food industry but also in other industries. The beauty industry has become a trend among teenagers. Based on BPS data, the cosmetics-skincare industry grew by 5.59% even during a pandemic where almost all industries experienced a decline. With a Muslim-majority country, the beauty industry is required to provide and create halal-certified skincare products. This study was conducted to determine the awareness of Gen-Z in buying halal-certified skincare cosmetics in online shopping. By using the Solvin formula to determine the number of samples. The study was conducted on 396 students in Jambi City. The results obtained show that almost 90% of Gen-Z buying cosmetics-skincare in online shopping see halal certification and use cosmetic local product Indonesia.

Abstract

Stocks are certificates that show proof of ownership of a company, and shareholders have claim rights to the company's profits and assets. To measure the company's performance in stocks, several ratios can be used. This study aims to determine the effect of net profit margin (NPM), current ratio (CR), and total asset turnover (TATO) on the profitability (ROA) of Retail Trading companies on the IDX. In this study using descriptive quantitative methods and the analysis used is panel data regression analysis. Panel data regression analysis is used to determine the effect of financial ratios on company profits. The population in the research is 93 companies in the retail trade sub-sector. By using purposive sampling obtained a sampling of 14 companies with a total of 42 samples. The results of this study indicate that the variable current ratio (CR) has a positive effect on return on assets (ROA), while net profit margin (NPM), total asset turnover (TATO) has a negative effect on return on assets (ROA). The model has an effect of 78%, the rest is influenced by other factors outside the research.

Abstract

Artikel ini membahas implementasi algoritma Sherman-Morrison untuk menyelesaikan sistem persamaan linier, di mana A merupakan matriks nonsingular berukuran n×n sehingga sistem memiliki solusi tunggal. Penelitian ini dilatarbelakangi oleh kebutuhan pendekatan penyelesaian yang adaptif dan efisien bagi sistem linier yang mengalami perubahan lokal secara berulang. Algoritma Sherman-Morrison merupakan bentuk khusus dari rumus Sherman–Morrison–Woodbury yang berlaku untuk modifikasi rank-satu, sehingga memungkinkan pembaruan invers matriks tanpa perhitungan ulang secara menyeluruh. Kajian dilakukan melalui pembuktian teoritis rumus tersebut dan implementasi komputasional menggunakan MATLAB R2013a. Implementasi disusun sebagai fungsi khusus yang dikembangkan secara modular untuk mengeksekusi langkah-langkah algoritma. Pengujian dilakukan terhadap empat jenis matriks: acak penuh, simetris positif definit, jarang (sparse), dan hampir singular. Evaluasi mencakup akurasi solusi, error residual, serta waktu eksekusi, kemudian dibandingkan dengan metode standar (A\b). Hasil implementasi menunjukkan bahwa algoritma memberikan solusi yang akurat dan efisien pada sistem dengan skala kecil serta matriks sparse, namun cenderung tidak stabil bila diterapkan pada matriks yang hampir singular. Dengan demikian, algoritma ini layak digunakan untuk kasus pembaruan rank-satu dengan kondisi yang baik, serta relevan untuk penerapan dalam konteks pembelajaran dan komputasi numerik.

Abstract

ABSTRACTThe limited technological literacy and teachers’ ability to integrate digital learning media remain major challenges in implementing the Merdeka Curriculum. Addressing this issue, this study introduced the development of E-COMATS (Ethnomathematics Comic Augmented Reality for Teaching and Learning) grounded in local cultural contexts, specifically Rumah Adat Kajang Leko. The objective was to train junior high school teachers to design interactive ethnomathematics-based media using Augmented Reality (AR) in order to foster deep learning and enhance digital competence. The program was conducted as community service in an onsite workshop at SMAN 8 Muaro Jambi, engaging lecturers, students, and partner teachers. A hands-on approach was applied, starting from the introduction of ethnomathematics concepts, E-COMATS design, AR feature integration, to the production of ready-to-use media. Findings revealed that more than 85% of teachers successfully produced AR-supported E-COMATS independently, while questionnaire results showed an increase in technological literacy with an average score of 4.35 out of 5. Participants perceived the developed media as relevant, innovative, and applicable in classroom practices. These results indicate that ethnomathematics-based E-COMATS training supported by AR is effective in improving teachers’ digital literacy and strengthening the integration of local culture into mathematics learning.Keywords: Augmented Reality, E-COMATS, Ethnomathematics, Junior High School Teachers, Technological Literacy ABSTRAKRendahnya literasi teknologi dan kemampuan guru dalam mengintegrasikan media pembelajaran digital masih menjadi tantangan utama dalam penerapan Kurikulum Merdeka.

Abstract

The deductive structure is fundamental in mathematics, but students often struggle to derive logical consequences when constructing proofs or engaging in the bridging process. This study analyzed students’ ability to deduce logical relationships between properties in geometric thinking on quadratic functions. The participants were students (N=139) from the mathematics education program. The properties of quadratic functions and their interrelationships contained in the premises represented students’ responses to the instrument. The responses were dichotomously coded based on the criteria of the carried-out deduction process and then evaluated using Rasch analysis. The findings revealed that, in general, the distribution of students’ ability levels was below most levels of the carried-out deduction process. Although a group of students had already reached the high-ability category, the overall distribution was still dominated by low-ability levels. Many students continued to face serious challenges in reaching the final stage of the deduction process—advanced premise integration and deductive synthesis—since most of them established relationships among properties merely from the given information. There were indications that learning experiences during higher education contributed positively to the improvement of students’ ability at the deduction level. The study recommends four steps to habituate students to the process of deduction.
