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

Generasi muda di zaman sekarang memiliki peran strategis dalam upaya meningkatkan kualitas dalam bidang pertanian. Desa Sungai Duren merupakan salah satu Desa tertua di provinsi Jambi Desa ini di bagi menjadi 3 dusun yaitu dusun tuo, dusun baru, dan pasir raya. Melihat dari data penduduk menyatakan bahwa petani Desa Sungai Duren didominasi oleh petani dengan usia rentang 45-60 tahun. Potensi yang dapat dikembangkan didesa menjadi salah satu faktor pendukung dari program inovasi desa yang mengambil tema sanggar tani muda dengan judul “Pemberdayaan Pemuda Menunjang Produktivitas Tanaman Hortikultura Berbasis Hidroponik”. Sehingga tim kami memiliki solusi terhap pemberdayaan pemuda di Desa Sungai Duren, Kecamatan Jambi Luar Kota, akan berfokus pada peningkatan produktivitas tanaman hortikultura melalui metode hidroponik. Hidroponik adalah teknik bercocok tanam tanpa menggunakan tanah, melainkan menggunakan larutan air yang mengandung nutrisi sebagai media tanam. Maka dari itu program ini bertujuan untuk melibatkan generasi muda dalam pertanian modern, meningkatkan keterampilan, dan mendorong inovasi dalam budidaya tanaman.

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.
