https://scientificacademic.com/index.php/tsj <p style="user-select: auto;">The Tropical Scientific Journal (TSJ) is a peer-reviewed open-access journal. It publishes two issues every year as March-August and September-February. TSJ follows a quick online first policy and updates the running issue regularly. It publishes the articles immediately on the acceptance and serves as a forum for the publication and dissemination of original research works. TSJ also published special issues based on requests. The scope of the journal is not only limited to science and technology issues but also related to creativity and innovation in scientific research works.</p> en-US Tropical Scientific Journal 2710-5997 https://scientificacademic.com/index.php/tsj/article/view/47 <p><strong>Objective:</strong><br>This study aims to develop and validate a structural model that examines trustworthiness as a mediating variable between user perceptions specifically Perceived Ease of Use (PEOU) and Perceived Usefulness (PU) and the intention to adopt AI technologies in ADNOC’s supply chain management.</p> <p><strong>Research Method:</strong></p> <p>A conceptual model was formulated based on the Technology Acceptance Model (TAM) and relevant literature. Primary data were collected through a structured questionnaire survey administered to 328 employees of the ADNOC supply chain department. The model was tested using Partial Least Squares Structural Equation Modeling (PLS-SEM) via SmartPLS software.</p> <p><strong>Findings:</strong><br>The results confirmed that all constructs exhibited strong internal consistency, convergent validity, and discriminant validity. Structural model analysis showed that PEOU and PU significantly influence Trust, which in turn strongly predicts Behavioral Intention to Use (BIU). The model demonstrated moderate to strong explanatory power and substantial predictive relevance, highlighting trust as a critical mediator in AI adoption.</p> <p><strong>Originality:</strong><br>This study extends the traditional TAM by incorporating trustworthiness as a mediator, offering a novel perspective on AI adoption in high-stakes, public sector environments. The validated model provides both theoretical contributions and practical insights for guiding successful AI implementation in complex organizational settings like ADNOC.</p> Mai Ali Mohammed Ali Alshamsi Norasmiha Mohd Nor Copyright (c) 2025 Tropical Scientific Journal https://creativecommons.org/licenses/by-nc-sa/4.0 2025-08-02 2025-08-02 4 2 84 105
