Digital Advertising and Customer Purchase Decisions in the Hospitality Industry: Evidence from Hyatt Hotels in Indonesia

/0 Comments/in /by

Digital advertising has become a critical strategic tool for hospitality firms seeking to influence customer behavior and enhance competitiveness in increasingly digitalized markets. This study aims to examine the effects of multiple digital advertising channels—namely e-mail marketing, mobile marketing, social media marketing, search engine marketing, affiliate marketing, and website marketing—on customer purchase decisions at different stages of the decision-making process in the hospitality industry. A quantitative research design was employed using a survey method, with 170 customers who had stayed at Hyatt Hotels in Indonesia within the past 6–12 months selected through purposive sampling. Data were collected using structured questionnaires and analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The results of the measurement model assessment confirm that all constructs demonstrate satisfactory validity and reliability. The findings indicate that digital advertising channels exert differentiated effects across the customer decision journey. E-mail marketing, social media marketing, and search engine marketing significantly influence the information search stage, while mobile marketing and search engine marketing affect the evaluation of alternatives. Notably, affiliate marketing exhibits a significant positive effect across all stages, including the final purchase decision, highlighting its critical role in driving conversion. Conversely, website marketing does not show a significant impact at any stage of the purchase decision process. These findings underscore the importance of aligning digital advertising strategies with specific stages of customer decision-making. The study provides managerial implications for hospitality firms to adopt an integrated, channel-specific digital advertising strategy to enhance customer engagement and improve purchase conversion in competitive hospitality markets.

Nutritional Retention and Sensory Properties of Novel Tropical Vegetable Juice Formulations Prepared via Non-Thermal Processing

/0 Comments/in /by

The development of functional beverages derived from tropical vegetables offers growing potential within the global health-focused food sector. This study formulated and evaluated three non-thermally processed Tropical Vegetable Juice Formulations (TVJF) using Ipomoea aquatica (kangkung) as the primary raw material. The objectives were to compare nutrient retention between juice and raw leaves, assess consumer sensory acceptance across different formulations, and evaluate commercialisation potential. Proximate and mineral analyses were conducted on TVJF-K and compared with raw vegetable samples using standard AOAC methods, while sensory evaluation of three formulations (TVJF-1, TVJF-2, and TVJF-3) employed a 5-point hedonic scale assessing colour, aroma, texture/stability, flavour, and overall acceptance among 30 untrained panelists. Results indicated that the juice retained approximately 80–95% of key minerals, particularly calcium, magnesium, iron, and copper, demonstrating effective preservation through non-thermal cold extraction. Sensory analysis revealed no significant differences (p > 0.05) in colour, aroma, flavour, or overall acceptance among formulations, although texture/stability differed significantly (p = 0.02). All formulations achieved mean scores above 3.0, indicating favourable consumer acceptance. These findings demonstrate that simple non-thermal processing can maintain both nutritional integrity and sensory quality in tropical vegetable juices, highlighting strong potential for industrial application, product diversification, and expansion within the regional functional beverage market.

Building Trust in Agentic AI: TRACE Framework for Policy-Driven Multi-Agent System Design

/0 Comments/in /by

The rapid adoption of multi-agent AI systems— ranging from prescriptive, workflow-driven deployments to fully agentic, autonomous ecosystems—raises urgent challenges for trust, accountability, and regulatory compliance. This paper introduces the TRACE Framework (Trust, Review, Accountability, Critique, Explainability), a governance-first architecture designed to make multi-agent AI systems auditable, policy-aligned, and operationally reliable across varying degrees of agent autonomy. TRACE embeds governance anchors at the agent level, enforces data privacy and policy checks, supplies a dedicated Critic agent for meta-validation, and preserves human-in- the-loop oversight where required. We present a layered architecture that separates Governance & Compliance, Operational Agents, and Oversight & Assurance, and provide a concrete methodology for instrumenting agent behaviour with provenance, explainability outputs, and per-agent metrics. A formal scoring rubric—comprising agent operational metrics, critic checks, and aggregation rules—yields an Overall System Confidence (OSC) that drives automated actions, human escalation, and continuous learning. Finally, we propose a suite of operational KPIs for each layer as Governance and Compliance Indicators (GCI), Agentic Performance Metrics (APM), and Assurance Indicators (AI) that enable financial institutions and other regulated organisations to deploy multi-agent systems that are efficient, auditable, and compliant. TRACE bridges the gap between regulatory expectations and system engineering practice— providing a practical roadmap for trustworthy multi-agent AI deployment in high-stakes domains.

How Job Satisfaction Shapes Affective Commitment: The Moderating Roles of Innovative Climate and Innovative Behavior in a Government Institution

/0 Comments/in /by

Public sector organizations face persistent challenges in strengthening employees’ affective commitment within rigid bureaucratic structures and increasing demands for innovation. Job satisfaction remains a critical issue, and efforts to promote an innovative climate and innovative behavior do not always translate into stronger emotional attachment to the organization. These conditions highlight the importance of understanding how job satisfaction and innovation-related factors interact in shaping affective commitment. This study examines the effect of job satisfaction on affective commitment, with innovative climate and innovative behavior tested as moderating variables. A quantitative explanatory design was employed using a census survey of 115 civil servants and probationary civil servants at the Regional Office XII of the National Civil Service Agency in Pekanbaru, Indonesia. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). Job satisfaction was modeled as a second-order construct reflected by satisfaction with pay, promotion, supervision, coworkers, and the work itself. The results indicate that job satisfaction has a positive and significant direct effect on affective commitment. Innovative climate and innovative behavior also show significant direct effects, but their moderating effects are not supported. Satisfaction with promotion emerges as the most dominant dimension, followed by satisfaction with pay and supervision. Overall, job satisfaction remains the primary antecedent of affective commitment, while innovative climate and innovative behavior act as complementary contributors. These findings highlight the importance of fair career advancement, equitable compensation, and supportive organizational practices.

This study aimed to evaluate the effect of adding a combination of calcidiol and betaglucan to feed on the production performance of laying hens aged 0–21 days, immune organ morphometry, and blood hematology of laying hens aged 12 weeks. The study used 500 Day-Old Chicks (DOC) of the Hy-Line Brown strain, divided into two treatments. The data obtained were analyzed using the Independent T-Test and descriptively for variables related to body weight uniformity and mortality. Treatment T0 = basal feed (control), T1 = basal feed supplemented with calcidiol 5.000 IU/kg and betaglucan 40mg/kg in the feed. The results showed that the addition of a combination of calcidiol and betaglucan had a significant effect (P < 0.01) on increasing feed efficiency in group T1 during the third week, resulting in a 21.51% improvement in feed conversion and bone marrow density at 12 weeks of age. The treatment did not have a significant effect (P > 0.05) on spleen and bursa morphometry, blood hematology, IgG, and IgM levels. Descriptively, the addition of Calcidiol-Betaglucan had a better effect on body weight uniformity, which was 3.84% higher than the control, and total mortality, which was 0.49% lower in T1 than in T0. The conclusion of this study is that the addition of the combination of calcidiol and betaglucan has potential as a functional feed additive to support early growth efficiency and immune system readiness in laying hens.

This study examines technological readiness as a mediator in the relationship between digital transformation and public value, filling an important gap in the literature about causal pathways in developing countries. Combining theories of digital transformation, technological readiness, and public value, the research involved 200 digital service users in Malang City. Bootstrap mediation analysis showed that digital transformation significantly affects public value (β=0.4146, p<0.001), with technological readiness mediating 35.51% of the total effect (ACME=0.1497), while the direct effect remained notable (ADE=0.2650). Results indicate partial mediation, implying that digital transformation adds value through two pathways. The study proposes a dual-pathway model that highlights the importance of investing in both digital infrastructure and user literacy, guiding comprehensive digital policies and broadening understanding of digital transformation in Indonesia’s context, characterized by high technological readiness heterogeneity.

Combined Drying Technologies for Preserving the Quality of Backyard Averroha Carambola L. in Veracruz, Mexico

/0 Comments/in /by

Star fruit (Averrhoa carambola L.) is cultivated in Asian and Latin American countries and has high nutritional value due to its content of bioactive compounds, polyphenols, vitamins A and C, minerals, and antioxidant activity. However, its high water content makes it highly perishable, limiting its preservation and commercialization; therefore, it is necessary to develop technological alternatives that extend its shelf life without affecting its organoleptic and nutritional quality. The objective of this study was to evaluate combined power ultrasound-assisted drying technologies for obtaining star fruit flakes as a preservation alternative, analyzing their effect on physicochemical, functional, and sensory attributes. Fruit from the Postgraduate College, Veracruz Campus, was used, and osmotic dehydration (OD) curves were performed at 50 and 60 °Brix, using ultrasound (US) as a pretreatment to convective drying (CS). Drying kinetics were performed at 50 and 60 °C, and total phenolic compounds, antioxidant activity (DPPH and ABTS), oxalic acid, color (ΔE), moisture, total solids, water activity (aw), and texture in the center and periphery were evaluated, in addition to sensory analysis. The DO treatments assisted with ultrasound reached equilibrium in less time. The 60°Brix-CUS-60 °C treatment showed lower final moisture content, while the 60°Brix-CUS-50 °C treatment reached an aw of approximately 0.47, favoring microbiological stability. The 60 °Brix DO treatment with ultrasound and 60 °C surface drying showed lower moisture content and higher total solids content. The 60 °Brix DO treatment without ultrasound and 50 °C surface drying preserved phenols better, reducing oxalic acid by >50% and showing improvements in antioxidant activity. High sensory acceptability was obtained. It is concluded that the DO-US-SC combination is effective in preserving carambola with adequate quality and acceptance.
