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.

Abstract

Private Higher Education Institutions (PHEIs) play a significant role in advancing educational opportunities and national competitiveness, yet they face critical challenges in governance, resource efficiency, and stakeholder satisfaction. This study proposes a comprehensive governance framework integrating Total Quality Management (TQM), Enterprise Architecture (EA), and value creation strategies to address these challenges. Using Structural Equation Modeling (SEM) and qualitative insights from pilot implementations at Indonesian PHEIs, the framework identifies key interdependencies among service quality, institutional strategies, and operational outcomes. The results demonstrate that aligning academic and non-academic systems with strategic objectives enhances governance effectiveness, stakeholder engagement, and institutional performance. This research provides practical recommendations for policymakers and practitioners, highlighting the importance of technology adoption, continuous feedback, and capacity building for sustainable governance transformation

Abstract

This study aimed to address Indonesia's critical environmental issue of waste management by designing optimal user services for an eGovernment waste management application. The research is exploratory in nature, employing a combination of qualitative and quantitative methods to develop an integrated digital solution. Our methodology includes data analysis from World Bank reports, insights from the Ocean Conservancy, and the examination of government policies and advanced technological applications. The results demonstrated the urgent need for efficient waste management systems, as Indonesia is the second-largest contributor to oceanic plastic waste. We propose a framework for an e-Government application that leverages Internet of Things (IoT), big data, and digital platforms to monitor, manage, and optimize waste management processes, enhancing transparency and effectiveness. Our findings suggested that the application's user-centric design significantly improves community engagement and participation in sustainable waste practices. The implications of this research point towards a scalable and sustainable model for waste management that can be adopted by other regions facing similar challenges. We recommend further development of the application with a focus on user feedback and iterative design to ensure adaptability to diverse waste management contexts. The contribution of this study lies in its potential to revolutionize waste management practices through digital transformation, providing a blueprint for environmental sustainability initiatives within e-Government frameworks. Keywords: waste management, digital transformation, E-Government Applications, sustainability, user services

Abstract

Tourism sector has been identified contribute to the economy of Lampung Province. The study aims to assess the direct and indirect linkage towards economic sectors, analyze the sensitivity of tourism sector distribution, to assess the multiplier effect of dispersion in the tourism sector, and calculate the final demand of tourism sector in the economy of Lampung Province. The results revealed that the score of the forward linkages from the tourism sector in Lampung is relatively small compared to the backward linkage. Both directly and indirectly, the tourism sector is a 'down stream' sector of Lampung economy, which the output is directly consumed by final consumers. Therefore if tourism sector is developed, it can pull output that is in the upstream sector. Keywords: development, forward and backward linkages, local economy, multiplier effect, tourism economy.
