Abstract

The research entitled “Application of the Lagrange Interpolation Method in Predicting the Number of HVS Orders in Printing” aims to develop an accurate forecasting model for the number of HVS orders in the printing industry. In this study, the Lagrange interpolation method was chosen because it can provide estimates by considering limited historical data. The analyzed data ranges from January 2021 to November 2022 and is processed to build a forecasting model. The results showed that the interpolation model built was able to capture well the fluctuation pattern of the order quantity. Model evaluation is carried out using Mean Absolute Percentage Error, which reads <=10%, indicating high prediction accuracy. In addition, sensitivity analysis to data variations showed consistent results of the prediction, thus strengthening the validity of the method. These findings suggest that Lagrange interpolation is an effective tool in forecasting HVS demand, providing advantages in inventory management and production planning in printing houses.

Abstract

The phenomenon of street children is one of the complex social issues in Indonesia. Many factors contribute to children living on the streets, such as poverty, family instability, lack of access to education, and exploitation by certain parties. This study aims to analyze the protection and education of street children from an Islamic perspective, as well as the challenges they face in their daily lives. The research employs a qualitative method using interviews and observations of several street children. The findings indicate that these children encounter various obstacles, including social stigma, lack of family attention, and limited access to education and healthcare. From an Islamic perspective, children have the right to receive protection, affection, and proper education. Therefore, collaboration between families, communities, religious institutions, and the government is necessary to provide sustainable solutions for street children.

Abstract

This study analyzes the influence of financial ratios and firm size on bond ratings of banking companies listed on the Indonesia Stock Exchange (IDX) for the 2019-2024 period. The independent variables include liquidity (Current Ratio), leverage (Debt to Equity Ratio), profitability (Return on Assets), and firm size (Size), with bond ratings as the dependent variable. A quantitative method with ordinal logistic regression is employed to examine the relationships among these variables. Secondary data were obtained from banking companies’ financial reports and bond ratings issued by PT Pefindo. The findings indicate that profitability (ROA) has a significant negative effect on bond ratings, suggesting that highly profitable companies do not necessarily receive better ratings. Meanwhile, leverage (DER), liquidity (CR), and firm size do not significantly impact bond ratings. The regression model is validated with a Nagelkerke R2 value of 0.784, indicating that the independent variables explain 78.4% of the variation in bond ratings. These results provide insights for investors and stakeholders that profitability plays a more critical role in determining bond ratings than other financial factors. Therefore, banking companies should optimize their profitability management to enhance bond credibility in financial markets.
