Abstract

This paper examines the impact of regulations and policies on the development of e-business in Indonesia. As e-business becomes increasingly integral to the economy, understanding the regulatory environment is crucial for stakeholders, including policymakers, business owners, and consumers. The study explores the current regulatory framework governing e-business in Indonesia, identifying key policies that influence its growth and development. Through qualitative analysis of government regulations, industry reports, and expert interviews, the paper highlights both the supportive and restrictive aspects of these regulations. Findings indicate that while certain policies, such as tax incentives and infrastructure investments, have fostered e-business growth, others, including stringent data protection laws and complex compliance requirements, pose challenges. The research underscores the need for a balanced regulatory approach that promotes innovation while ensuring consumer protection and fair competition. Recommendations are provided for policymakers to enhance the regulatory landscape, suggesting measures such as streamlined compliance processes, enhanced digital literacy programs, and increased collaboration between government and industry stakeholders. Ultimately, this paper aims to contribute to the discourse on how regulations can be optimized to support the sustainable growth of e-business in Indonesia, aligning with broader economic goals and technological advancements.

Abstract

This study aimed to deepen the understanding of the decision-making process supporting the acceptance of Cryptocurrency mobile apps by integrating relevant factors into the Traditional Technology Acceptance Model (TAM). The impact of Antecedent System Characteristics (Relevance, Terminology, and Screen Design), Perceived Risk, and Trial ability on the existing TAM-3 constructs was investigated. A survey questionnaire was distributed among mobile cryptocurrency app users, resulting in 41 responses. The proposed framework was evaluated using the SEM-PLS method, including confirmatory factor analysis (CFA), and its construct validity was confirmed. Invariance tests were conducted on both the measurement and structural models. While most findings supported the suggested model, exceptions were found regarding Terminology and Perceived Risk of Cryptocurrency Mobile Application Adoption. The extended TAM factors, unlike the traditional TAM, accounted for 45% of the variance in the actual usage of cryptocurrency mobile apps. The revised model demonstrated improved predictive and explanatory power, particularly in explaining Perceived Ease of Use, which the traditional model could not. The study highlights the occurrence of inconsistencies between the original TAM model constructs and the added constructs when expanding the Technology Diffusion theory. Nonetheless, the model in this study enhances predictive capabilities and provides a comprehensive explanation of users' acceptance of mobile cryptocurrency applications.Keywords: TAM-3, Cryptocurrency, technology diffusion theory, integrating relevant factors, decision making process

Abstract

Purpose: This study aims to examine the influence of Customer Review and E-Service Quality, on purchase decisions mediated by the level of customer trust of the Shopee Application Methodology/Approach: The testing method used in this study was a quantitative method. This study used a questionnaire to collect data. The questionnaire was distributed by random sampling through Google Forms. Hypothesis testing was performed using a Structural Equation Model (SEM). Results/Findings: The results showed that online customer reviews had no effect on shopee purchase decisions, e-service quality had an effect on shopee purchase decisions, trust had an effect on shopee purchase decisions, trust weakened the influence of customer reviews on purchase decisions and trust weakened the influence of customer reviews on decisions purchase.Conclusions: Online customer review tidak berpengaruh terhadap keputusan pembelian di Shopee, sedangkan e-service quality dan trust memiliki pengaruh signifikan terhadap keputusan pembelian. Selain itu, trust memperlemah pengaruh customer review terhadap keputusan pembelian, sehingga Shopee perlu meningkatkan kualitas pelayanan inti untuk menjaga kepercayaan pelanggan.Limitations: This research is only limited to the variables of online customer reviews, e-service quality trust, and purchase decisions. There are many other factors that are very likely to be raised and explored for future research.nContribution: This research is expected to improve the purchase decisions and serve as a reference for further research.

Abstract

This study applies Monte Carlo simulation to analyze and compare the Value at Risk (VaR) of two Indonesian airline stocks—PT Garuda Indonesia (full-service carrier) and PT AirAsia Indonesia (low-cost carrier)—using daily return data from January to December 2023. The research examines risk-return characteristics at individual stock and portfolio levels across different confidence intervals (99%, 95%, and 90%). Results reveal that PT Garuda Indonesia exhibits higher expected returns (0.5168%) but also higher volatility (3.5980%) compared to PT AirAsia Indonesia (0.2412% return, 2.4868% volatility), reflecting their different business models. Remarkably, an equal-weight portfolio demonstrates extraordinary diversification benefits, with positive VaR values across all confidence levels, indicating robust downside protection even in adverse market conditions. At 99% confidence, the monetary VaR for a Rp100,000,000 investment shows potential maximum losses of Rp7,984,331 for Garuda and Rp5,460,951 for AirAsia, while the portfolio generates a minimum gain of Rp1,886,373. This study highlights the effectiveness of Monte Carlo VaR in capturing complex risk dynamics, demonstrates significant intra-sector diversification benefits challenging conventional diversification wisdom, and provides insights into how different airline business models translate into distinctive risk-return profiles. These findings have important implications for investment decision-making and risk management in specialized industry contexts, particularly in emerging markets.
