Abstract

This study investigates the mediating role of AI capabilities in the relationship between technology features and user engagement among Generation Z, with a cross-cultural focus on Indonesia and Hungary. The aim is to explore how cultural and technological contexts shape marketing innovation and user behavior. The research employs Partial Least Squares Structural Equation Modeling (PLS-SEM) and Multi-Group Analysis (MGA) to analyze survey data from 743 Generation Z respondents (415 in Indonesia and 328 in Hungary). The study examines direct and mediated relationships between technology features, AI capabilities, and user engagement, and tests cross-cultural differences. The results reveal that AI capabilities significantly mediate the effect of technology features on user engagement, with notable differences between the two countries. Indonesian Gen Z emphasizes the direct and mediated effects of technology features, leveraging immersive and interactive platforms, while Hungarian Gen Z prioritizes ethical and sustainability-driven AI solutions as key drivers of engagement.  The study is limited to Generation Z in two countries, and future research could expand the scope to include other generational cohorts and regions. Longitudinal studies and behavioral data could also enhance the understanding of evolving user engagement dynamics. The findings highlight the importance of integrating AI-driven personalization, interactivity, and predictive analytics into marketing strategies to enhance engagement. Businesses targeting Gen Z should tailor their approaches to specific cultural and technological contexts, leveraging immersive technologies in Indonesia and sustainability-focused AI in Hungary. This research underscores the potential of AI and technology features to shape ethical and sustainable consumption patterns among Generation Z, informing corporate social responsibility and digital marketing practices. The study provides a quantitative hierarchy of relationships between technology features, AI capabilities, and user engagement, validated across culturally diverse contexts. It offers actionable insights for businesses and contributes to the theoretical understanding of cross-cultural technology adoption and marketing innovation. Keywords: Generation Z, AI Capabilities, User Engagement, Technology Features, Cross-Cultural Analysis

Abstract

Abstract: This research aims to develop a business resilience model on MSMEs during COVID-19 theoretically and empirically. This research uses the TCM method for literature review analysis and SEM for model testing. The object population of this research is MSMEs in a rural area in Indonesia. The sample of this research is 301 MSME owners who are still surviving during COVID-19. The results reveal no significant direct influence of government support assistance on business resilience. However, government support assistance, knowledge management, and innovation through technopreneur have a significant impact on digital transformation, and then digital transformation on business resilience. The research made new theoretical and empirical contributions of MSMEs to utilize government support in business resilience models and knowledge management and innovation concerning entrepreneurship. Keywords: Business resilience; COVID-19; digital transformation; government assistance; innovation; knowledge management; MSMEs; technopreneur.

Abstract

This study examines Indonesia’s export performance in an agribusiness product at the HS 6-digit level (HS 1511) over 2015-2023 by combining revealed competitiveness indicators and structural gravity estimation. First, we compute the Revealed Comparative Advantage (RCA) index to assess Indonesia’s export specialization relative to world trade. Second, we estimate a Poisson pseudo-maximum likelihood (PPML) gravity model with year fixed effects to identify the roles of destination market size, trade costs, and trade agreement coverage. Bilateral exports are constructed from UN Comtrade, macroeconomic controls are drawn from the World Development Indicators, bilateral distance and dyadic controls are obtained from CEPII, and trade agreement status is coded from DESTA at the dyad–year level using an in-force rule. Results indicate that Indonesia retains a strong revealed comparative advantage (RCA > 1 in all years), although the average RCA declines between early and late sub-periods. Gravity estimates show that destination market size (particularly population) positively predicts exports, while distance reduces expected export values. Importantly, in-force regional trade agreements are associated with significantly higher bilateral exports, approximately 48% larger export values, ceteris paribus, highlighting the relevance of policy-enabled market access alongside traditional gravity fundamentals. These findings emphasize the joint importance of competitiveness, trade-cost reduction, and effective utilization of trade agreements for sustaining and expanding Indonesia’s agribusiness exports. Keywords: comparative advantage, gravity model, Indonesia, PPML, trade agreements

Abstract

This study develops an integrated sustainable supply chain strategy to strengthen the global competitiveness of clove commodities in North Sulawesi. The research employs a qualitative descriptive approach, involving farmers, collectors, exporters, and government institutions, to examine supply chain conditions, identify internal and external strategic factors, and formulate actions to improve long-term competitiveness. Using SWOT, IFAS–EFAS, and TOWS analysis, the study reveals that intrinsic product quality, traditional knowledge, and strong social networks form the core strengths of the upstream actors, while major weaknesses include aging trees, inconsistent post-harvest quality, limited logistics infrastructure, and restricted market access. Externally, the clove sector has strong opportunities in premium global markets, digital supply chain transformation, certification potential, and product diversification; yet it faces significant threats, including international competition, price volatility, climate risks, and non-tariff trade barriers. The formulated strategies emphasize modernization of cultivation and post-harvest practices, digital traceability systems, structured replanting programs, cooperative-based distribution models, certification clusters, and the development of value-added derivative products. The study contributes a strategic roadmap that integrates sustainability, digitalization, and institutional collaboration to enhance supply chain efficiency, stabilize farmer welfare, and elevate the global market position of North Sulawesi cloves. Keywords: Clove supply chain; sustainable supply chain; competitiveness; TOWS strategy; IFAS–EFAS; agricultural value chain; digital traceability.

Abstract

Agricultural food supply chains are increasingly exposed to disruptions caused by climate change, market volatility, logistical bottlenecks, and operational uncertainty, with important implications for food continuity and environmental health. This study examines the roles of supply chain collaboration, supply chain flexibility, and supply chain agility in shaping agrifood supply chain robustness in the laying hen sector of North Sulawesi, Indonesia. A quantitative cross-sectional design was employed, and data were collected from 180 valid respondents involved in the laying hen supply chain between July and October 2025. The data were analyzed using partial least squares structural equation modeling (PLS-SEM) to test both direct and indirect relationships among the latent constructs. The results show that supply chain collaboration and supply chain flexibility have significant positive direct effects on agrifood supply chain robustness. Supply chain agility also has a significant direct effect and emerges as the strongest predictor of robustness. In addition, agility significantly mediates the effects of collaboration and flexibility on robustness, indicating that coordinated relationships and adaptive structures become more effective when translated into rapid operational responses. These findings suggest that resilient agricultural food supply chains depend on the integration of collaboration, flexibility, and agility to maintain supply continuity, reduce disruption impacts, and support safer and more sustainable food systems. The study contributes to the literature on agrifood resilience by linking dynamic supply chain capabilities with broader concerns of environmental health and offers practical implications for agribusiness managers and policymakers in developing regions. Keywords: Agrifood supply chain; Environmental health; Laying hen industry; Supply chain agility; Supply chain resilience
