This analysis focuses on consumers of The Body Shop within the Special Region of Yogyakarta. Adopting a quantitative research design, this study employed a survey method involving the distribution of questionnaires to 150 respondents, who were recruited through a purposive sampling technique. Respondents were consumers who understood that the research object was an environmentally friendly product, had purchase intentions, and were at least 17 years old. To test the proposed conceptual model, this study utilized Partial Least Squares-Structural Equation Modeling (PLS-SEM), with the analysis performed using SmartPLS software. The data confirms that green perceived value has a robust positive impact on trust, attitude, and purchase intention within the context of environmentally friendly products. Furthermore, both green trust and product attitudes significantly enhance purchase intentions. Mediation tests further confirm that these two variables serve as critical pathways through which green perceived value affects consumer intentions. This study confirms that green value perception is essential for fostering trust and positive attitudes, which are pivotal in translating consumer interest into actual green purchase intent. This study contributes by developing a model that positions attitude toward green products as an alternative mediator, thereby enriching our understanding of the psychological mechanisms influencing the purchase behavior of green products.</p> Hasnah Rimiyati Ilham Kusuma Wardana Copyright (c) 2026 Hasnah Rimiyati, Ilham Kusuma Wardana https://creativecommons.org/licenses/by/4.0 2026-04-30 2026-04-30 5 4 497 518 10.55927/ijar.v5i4.16362 Cultural Assimilation in the Shifting Trends of Muslim Fashion in Southern Europe https://journal.formosapublisher.org/index.php/ijar/article/view/16350 <p>The increasing migration of Muslim communities to Europe has significantly influenced fashion trends in the region. One of the most notable changes is the growing demand for Muslim fashion that aligns with modest fashion values. This phenomenon underscores the process of cultural assimilation within the fashion industry, wherein designers and major brands integrate elements of Muslim fashion into their collections. The adoption of modest fashion by global fashion houses not only reflects shifting consumer preferences but also demonstrates the interplay between cultural identity and commercial strategies. This qualitative study adopts a literature review and data analysis approach to examine the consumption and production of Muslim fashion in Southern Europe. The research aims to analyze the extent to which cultural assimilation influences fashion trends, the motivations of fashion brands in incorporating modest fashion, and the socio-economic implications that emerge from this phenomenon. Furthermore, this study seeks to explore the ethical and sustainability concerns surrounding the mass production of modest fashion and its impact on the labor market. A comprehensive understanding of these dynamics is imperative for stakeholders in the fashion industry to develop products that align with evolving consumer preferences while upholding ethical considerations and sustainability principles. By critically assessing the cultural and economic implications of this trend, this study contributes to a broader discourse on globalization, identity, and inclusivity within the fashion industry.</p> Jillena Oseta G Munthe Shobicatul Aminah David Ronald Tairas Copyright (c) 2026 Jillena Oseta G Munthe, Shobicatul Aminah, David Ronald Tairas https://creativecommons.org/licenses/by/4.0 2026-04-13 2026-04-13 5 4 405 418 10.55927/ijar.v5i4.16350 Flight-Log-Based Performance Analysis of a PID Controller for Pitch Response in a Quadcopter UAV https://journal.formosapublisher.org/index.php/ijar/article/view/16442 <p>This study analyzes the performance of an initial PID controller in the pitch channel of a quadcopter UAV using an empirical flight log exported from UAV Log Viewer. The aim is to evaluate pitch stability and command-following response by comparing desired pitch, current pitch, and North-East position data recorded during a 89.96s valid segment (2649 samples), analyzed through time-history inspection and error metrics. The method applies qualitative-quantitative log analysis with error metrics, time-history inspection, and trajectory interpretation. The results show weak pitch tracking: desired pitch varied from -1.34° to 4.14°, while measured pitch remained narrow at -0.73° to -0.50°; The log yielded MAE was 1.65°, RMSE was 2.04°, IAE = 148.46 degrees, and pitch correlation = 0.03.°. The findings imply that the initial gains are safe for data collection, but inadequate for responsive pitch control and require retuning.</p> Lalu Aan Sasaka Akbar Romie Oktovianus Bura Dwi Mandaris Ahmad Sahid Ani Widuri Copyright (c) 2026 Lalu Aan Sasaka Akbar, Romie Oktovianus Bura, Dwi Mandaris , Ahmad Sahid, Ani Widuri https://creativecommons.org/licenses/by/4.0 2026-04-29 2026-04-29 5 4 487 496 10.55927/ijar.v5i4.16442 Strategic Risk Assessment of Hazardous Energetic Chemicals in Defense Supply Chains: A Coupled Risk Framework for Ammonium Perchlorate (AP), RDX, and HMX https://journal.formosapublisher.org/index.php/ijar/article/view/16438 <p>Energetic materials such as ammonium perchlorate (AP), RDX, and HMX are essential in modern defense systems but pose multidimensional risks across industrial supply chains. This study presents a literature-based assessment integrating hazard profiling with node-based risk characteristics; RDX shows high acute process instability, AP poses environmental risks due to perchlorate mobility in groundwater, and HMX presents strategic coupling risk from production interdependence. A Coupled Risk Triangle Model is proposed, framing energetic chemical governance as a dynamic system linking reactive instability, environmental persistence, and strategic supply concentration. The findings indicate that risks extend beyond occupational safety to environmental regulation and national security resilience. Effective mitigation therefore requires lifecyle-integrated governance, supply diversification, and resilience-oriented industrial strategies.</p> Sulfi Indriani Sri Yanto I Nengah Putra Firdah Dipi Juni Kurniawati Copyright (c) 2026 Sulfi Indriani, Sri Yanto, I Nengah Putra, Firdah Dipi Juni Kurniawati https://creativecommons.org/licenses/by/4.0 2026-04-30 2026-04-30 5 4 473 486 10.55927/ijar.v5i4.16438 English Language Learning Model Training Based on ICT through Web-Based Learning in Subject Teacher Consultation Groups (MGMP) in Rokan Hulu Regency https://journal.formosapublisher.org/index.php/ijar/article/view/16371 <p>This community service project aimed to enhance English teachers’ competencies in integrating Information and Communication Technology (ICT) into teaching through web-based learning.
