Abstract

This study examines the effects of Return on Equity (ROE), Debt to Equity Ratio (DER), and Earnings per Share (EPS) on the stock prices of companies in the IDX Energy sector during the 2020–2024 period. The research is motivated by the high volatility in the energy sector due to the COVID-19 pandemic, post-pandemic recovery, and global commodity price fluctuations, which may influence investor responses to firm fundamentals.Using a quantitative approach, this study analyzes secondary data from 15 companies selected through purposive sampling, resulting in 75 firm-year observations. The data were analyzed using panel data regression.The results show that ROE and DER have positive but statistically insignificant effects on stock prices, while EPS has a positive and statistically significant effect. Simultaneously, all variables significantly affect stock prices, with the model explaining 56.45% of the variation.These findings indicate that EPS is the most relevant financial indicator in explaining stock price movements of IDX Energy companies during the study period.

Abstract

This study aims to examine the influence of Non-Performing Loan (NPL), Loan to Deposit Ratio (LDR), and Capital Adequacy Ratio (CAR) on profitability measured using Return on Assets (ROA) in state-owned banks listed on the Indonesia Stock Exchange for the 2018–2024 period. The research approach used is quantitative with multiple linear regression analysis methods. The research data is sourced from the annual reports of four state-owned banks, namely PT Bank Rakyat Indonesia Tbk, PT Bank Negara Indonesia Tbk, PT Bank Mandiri Tbk, and PT Bank Tabungan Negara Tbk. The analysis process is carried out through a partial test (t-test), simultaneous test (F-test), and calculation of the determination coefficient (R²). The results of the study revealed that partially, NPL had a significant negative influence on ROA with a regression coefficient value of -0.772 and a significance level of 0.000 < 0.05. The LDR variable did not show a significant effect on ROA with a significance of 0.092 > 0.05, nor did CAR which also had no significant effect with a significance of 0.648 > 0.05. However, simultaneously these three variables were shown to have a significant effect on ROA with F calculated at 19.744 greater than F in table 2.99 and Adjusted R² value of 0.676. This means that 67.6% of ROA variations can be explained by NPLs, LDRs, and CARS, while the remaining 32.4% are influenced by other factors outside of this research model.

Abstract

This study investigates the effectiveness of digital-based insurance learning in enhancing risk literacy among Indonesian society. Risk literacy is a critical component of financial literacy that enables individuals to understand uncertainty, evaluate potential risks, and make informed financial decisions. However, the level of public understanding of risk and insurance remains relatively low, highlighting the need for innovative and accessible educational approaches.This research adopts a quantitative approach using a quasi-experimental design with pre-test and post-test measurements. Data were collected from 120 participants who engaged in digital learning modules consisting of interactive videos, simulations, and case-based exercises related to insurance and risk management. Statistical analysis, including paired sample t-tests and regression analysis, was employed to assess the effectiveness of the intervention.The results indicate a significant improvement in participants’ risk literacy, as reflected by higher post-test scores compared to pre-test results. Furthermore, digital learning engagement was found to have a positive and significant influence on learning outcomes. These findings demonstrate that digital-based insurance learning is an effective and scalable strategy for improving public understanding of risk and insurance concepts.This study contributes to the development of an integrated framework combining digital learning, insurance education, and risk literacy. Practically, the findings provide insights for policymakers and educators in designing technology-driven educational programs to enhance financial literacy and risk awareness in Indonesia.

Abstract

The study examines the effectiveness of digital insurance education in improving risk literacy in Indonesia. Risk literacy is an essential part of financial literacy because it enables individuals to understand uncertainty, assess potential losses, and make informed financial decisions. Public understanding of risk and insurance, however, remains relatively low, which calls for more innovative educational strategies. A quantitative approach was applied through a quasi-experimental design using pre-test and post-test measures. Data were collected from 120 participants who completed digital learning modules consisting of interactive videos, simulations, and case-based materials on risk and insurance. Paired-sample t-tests and regression analysis were used to assess the effect of the intervention. The findings indicate a significant increase in participants’ risk literacy, as reflected in higher post-test scores than pre-test scores. Engagement in digital learning also showed a positive and significant effect on learning outcomes. The results suggest that digital learning can serve as an effective and scalable method for improving public understanding of risk and insurance. The study also provides a basis for an integrated framework linking digital learning, insurance education, and risk literacy. From a practical perspective, the findings may guide policymakers and educators in designing accessible and technology-driven educational programs to improve financial literacy and risk awareness in Indonesia.

Abstract

This study evaluates the structural determinants of Indonesia's manufacturing exports to Regional Comprehensive Economic Partnership (RCEP) member countries from 2007 to 2024. By utilizing a machine learning approach through the Random Forest algorithm within the Knowledge Discovery in Databases framework, this research transcends the rigid linearity assumptions of traditional econometric models. The computational model demonstrates superior predictive precision, with the model’s accuracy reaching a score of 0.983. A specialized variable importance analysis reveals that economic similarity is the primary catalyst for export flows, thereby strongly confirming the Linder hypothesis regarding intra-industry trade. Furthermore, fundamental gravity model variables, namely economic distance, population size, and gross domestic product, remain highly significant in dictating bilateral trade volumes. Interestingly, the empirical results indicate that the implementation of the RCEP pact and the global pandemic shock possess negligible immediate impacts on the export volume. This anomaly suggests a substantial time lag effect, as domestic industrial supply chains require a considerably long adaptation period to optimally capitalize on tariff eliminations. Consequently, this paper recommends strategic policy interventions for fiscal and customs authorities. The government must synergize logistical infrastructure improvements with targeted industrial incentives, particularly the super tax deduction for research and development and the Import Facility for Export Purposes. These synchronized efforts are essential to reduce economic distance friction, enhance structural competitiveness, and transform Indonesia's participation in the RCEP agreement into tangible manufacturing trade creation.

Abstract

This study examines the influence of digital capabilities and business synergy on digital transformation in higher education institutions facing rapid technological change. Universities are increasingly expected to adapt by strengthening their ability to use digital technologies while maintaining effective coordination across organizational units. Digital capabilities reflect the skills, knowledge, and readiness of institutions in utilizing technology, while business synergy refers to the alignment and collaboration among internal functions to support common goals. A total of ninety respondents from several universities were selected through purposive sampling, ensuring their relevance to digital practices and institutional development. The data were processed using Smart Partial Least Squares (Smart PLS) to evaluate the structural model and test the relationships between variables. The findings show that digital capabilities have a positive and significant effect on digital transformation. Business synergy also demonstrates a significant influence, indicating that coordinated efforts across departments support smoother implementation of digital initiatives. These results indicate that university performance in the digital era depends on the ability to strengthen technological competence and maintain strong internal collaboration. Institutions that are able to integrate both aspects tend to achieve more effective and sustainable transformation outcomes.

Abstract

This study aims to analyze the impact of online shopping experience quality on customer satisfaction among e-commerce users. Data was obtained from 200 respondents through a five-point Likert scale questionnaire and interviews to enrich the explanation of the quantitative results. The instrument was developed through focus group discussions and validated by academics and e-commerce practitioners. The analysis was conducted using SPSS, including validity, reliability tests, and both simple and multiple linear regression. The results indicate that the quality of the online shopping experience significantly affects customer satisfaction, with a coefficient of determination of 0.63. Delivery speed and accuracy emerged as the most dominant factors (β = 0.56; p < 0.001), followed by customer service quality (β = 0.49; p < 0.01), website ease of use (β = 0.42; p < 0.01), and transaction security and payment methods (β = 0.32; p < 0.05). A total of 73% of respondents were satisfied to highly satisfied, with an average score of 4.2 on a 1-5 scale. The findings suggest that logistics performance, customer service responsiveness, interface design, and payment security are the primary factors contributing to customer satisfaction on e-commerce platforms.
