Abstract

This study aims to compare the disclosure of Value at Risk (VaR) in market risk prediction among banks in Indonesia. By employing comparative and analytical methods, this research examines the effectiveness of VaR disclosure as a market risk prediction tool. Through the evaluation of VaR models disclosed by Indonesian banks and their comparison to a parametric model using asymmetric GARCH volatility for Variance Covariance Value at Risk, this study identifies the extent to which VaR disclosure can be relied upon to predict market risk. This research contributes to the understanding of risk management practices in the Indonesian banking sector and offers recommendations for improving market risk prediction accuracy through more effective VaR disclosures.

Abstract

Current study explored the connection between e-service quality, social networks, purchase intention, and customer trust, specifically focusing on how artificial intelligence impacts e-service quality within insurance companies. This research employed Theory of Planned Behavior as the basis foundation and conducted through a quantitative approach. Denpasar was used as the research location and targeting 150 local communities as respondents. Empirical data was collected through questionnaires and the analysis was performed using Structural Equation Modeling (SEM) with AMOS version 23 software. The findings indicate significant and positive relationships among all variables, leading to the acceptance of all hypothesis. The findings of this research show that the quality of AI-based services and social networks has a significant impact on the level of consumer trust in insurance products. A high level of trust in the quality of insurance products will in turn increase consumers' willingness to use these insurance products, thereby stimulating consumer loyalty towards insurance companies. The results of data analysis highlight that trust is a crucial key in consumer interest in purchasing a product. Interesting findings from this research also emphasize that gender, especially female consumers, show higher interest in insurance products. This is due to the belief that women have a high awareness of health and financial risks, thus motivating them to use insurance products.

Abstract

This study aimed to anticipate the rupiah loan interest rates at commercial banks in Indonesia by employing the Holt-winters method. This study employs data on rupiah loan interest rates from commercial banks in Indonesia. The data comprises a time series element, with monthly intervals spanning from January 2013 to November 2015, which was obtained from the official website of BPS Indonesia. The study demonstrates that the Holt-winters technique yields the most accurate forecasts, as indicated by a Root Mean Square Error (RMSE) of 0.19720630. The parameters alpha, beta, and gamma, set at 0.6, 0.6, and 0.6 respectively, constitute the optimal configuration for this method. These results indicate that the Holt-winters method is an effective tool for capturing seasonality, trends, and patterns in credit interest rate data, making it a reliable choice for future loan interest rate forecasting. The findings of this study are expected to significantly contribute to strategic decision-making in the banking sector, particularly in risk management and loan interest rate strategy determination.

Abstract

The banking industry in Indonesia is rapidly growing and becoming more competitive. Banks are striving to gain market share by offering innovative products and services and ensuring excellent customer service. XYZ has capitalized on this growth, evidenced by a 11.7% YoY credit growth in various sectors in 2022. Despite overall positive performance, some branch offices face challenges in optimizing productivity. This study aims to analyze factors influencing work productivity at XYZ. Six variables are examined leadership style, organizational culture, work environment, work motivation, job satisfaction, and work productivity. Data from 350 respondents at XYZ Bank K and L region were analyzed using SEM LISREL. The study finds that a significant direct influence was found between transformational leadership style and work environment on work motivation, adhocracy organizational culture and work environment on job satisfaction, and job satisfaction on work productivity at Bank XYZ. There is no significant influence between adhocracy organizational culture on employee work motivation, transformational leadership style on employee job satisfaction, transformational leadership style on work productivity, adhocracy organizational culture on work productivity, work motivation on work productivity, and work environment on work productivity at Bank XYZ . The mediating relationship that was not significant in this research was the relationship between transformational leadership style, adhocracy organizational culture, and work environment on work productivity through work motivation, as well as transformational leadership style on work productivity through job satisfaction. This research shows that there are two significant mediating relationships, namely adhocracy organizational culture influences employee productivity through job satisfaction and the work environment influences work productivity through job satisfaction. The managerial implication is that XYZ Bank should adopt a transformational leadership style, adhocracy organizational culture, and prioritize work environment improvements to enhance work motivation and job satisfaction, ultimately leading to increased work productivity.

Abstract

This study evaluates the hedging effectiveness of Indonesia’s national electrical company, PT PLN (Persero), by comparing Ordinary Least Squares (OLS), Generalized Autoregressive Conditional Heteroskedasticity (GARCH), and Dollar Offset models. Using transaction data from 2018-2023, the analysis shows that the OLS model explains 48.8% of the variance in forward rates, indicating high effectiveness. The GARCH model, while capturing dynamic volatility with an average effectiveness of 4.32%, demonstrates the need for advanced models in volatile conditions. The Dollar Offset method, despite its simplicity, shows a moderate effectiveness of 19.03%. Combining these methods can enhance hedging strategies, providing robust risk management. Future research should expand data sources and periods to further validate findings.

Abstract

Organizations are transitioning to become data-driven across all business aspects, including human resource management. The most crucial data managed is from Employee Engagement Surveys (EES). Organizations require process improvements to analyze EES results more quickly and accurately, even at the subsidiary level. This study implements the design science method to develop an artifact in the form of a Business Intelligence (BI) dashboard. The EES BI dashboard is evaluated using the Technology Acceptance Model (TAM) to assess user acceptance within the organization. The results indicate that the EES BI dashboard is well-received, with users demonstrating a high intention to use it. Thus, it is concluded that design science can be implemented to produce artifacts that assist organizations.
