Abstract

The emergence of Indonesian Muslim women scholars (ulama perempuan) marks a significant transformation in the contemporary Islamic legal discourse on gender and family law. Historically, fatwas have been predominantly issued by male scholars, often reflecting patriarchal interpretations of Islamic jurisprudence. This study aims to examine how ulama perempuan contribute to the development of progressive fatwas that promote gender justice, human dignity, and women’s rights within the framework of Islamic law. The research employs a qualitative descriptive design using content analysis of fatwas, interviews with members of Kongres Ulama Perempuan Indonesia (KUPI), and field observations of community-based legal education programs. The findings reveal that ulama perempuan reinterpret classical texts through a contextual and maqasid al-shariah approach, emphasizing principles of equality, compassion, and social welfare. Their fatwas address critical issues such as child marriage, domestic violence, reproductive rights, and environmental justice, demonstrating the dynamic interplay between religious authority and social advocacy. The study concludes that the intellectual and moral authority of ulama perempuan strengthens the democratization of Islamic jurisprudence in Indonesia and serves as a model for inclusive, gender-responsive Islamic scholarship globally.

Abstract

The increasing demand for renewable electricity drives the need to improve wind turbine efficiency under complex aerodynamic and structural conditions. Numerical approaches often separate airflow analysis and structural response, thus reducing the accuracy of predicting aeroelastic behavior. This study aims to analyze the effectiveness of multiscale fluid-structure interaction (FSI) modeling in improving wind turbine blade performance through integrated aerodynamic, structural, and material analysis. Using a mixed-method sequential explanatory design, the study tested 2,800 simulation scenarios on 48 blade configurations under varying wind speeds, turbulence intensities, and composite material properties. Quantitative analysis included multivariate statistics and hierarchical regression, while qualitative thematic analysis was drawn from expert interviews and engineering workshops. Results show that a fully coupled multiscale FSI model consistently outperforms conventional approaches in improving aerodynamic efficiency, computational convergence, structural stability, vibration damping, and fatigue life prediction. Composite material optimization enhanced structural robustness under dynamic conditions. This framework provides practical guidance for designers and engineers to optimize renewable energy conversion through advanced multiphysics simulations.

Abstract

Artificial intelligence has transformed e-commerce through algorithmic personalization systems that provide customized recommendations, predictive advertising, and individualized shopping experiences. By analyzing behavioral and transactional data in real time, these systems enhance consumer convenience, purchasing efficiency, and platform engagement. However, increased reliance on data collection and predictive analytics has intensified concerns regarding privacy intrusion, surveillance, and loss of control over personal information. This study aimed to examine the relationship between AI-driven personalization and consumer privacy anxiety in e-commerce environments. Particular attention was given to the effects of algorithmic customization on consumer trust, purchase intention, perceived convenience, emotional discomfort, and privacy-related concerns. A mixed-methods explanatory sequential design was employed involving 450 active e-commerce consumers from five major online shopping platforms. Quantitative data were collected through standardized questionnaires, while qualitative data were obtained through behavioral simulations, reflective response forms, and semi-structured interviews. Structural equation modeling, regression analysis, and correlation testing were used to examine relationships among variables. Results revealed that AI personalization significantly increased consumer engagement, perceived shopping convenience, and purchasing intention. Nevertheless, privacy anxiety and surveillance concerns remained evident despite positive attitudes toward personalization benefits. Perceived algorithmic transparency and greater consumer control over personal data reduced emotional discomfort and strengthened trust in digital platforms. These findings indicate that sustainable AI personalization requires the integration of technological efficiency, ethical transparency, consumer empowerment, and responsible data governance.

Abstract

The rapid expansion of hybrid learning environments has intensified existing equity and access disparities within multicultural classrooms, where students from linguistically, culturally, and socioeconomically diverse backgrounds encounter differential barriers to meaningful educational participation. Pedagogical frameworks designed for homogeneous learner populations remain inadequate in addressing the intersecting dimensions of cultural identity, digital access inequality, and instructional responsiveness that define contemporary multicultural educational contexts. This study aims to examine how hybrid learning environments can be deliberately designed to promote equity, broaden access, and enhance pedagogical responsiveness across multicultural classroom settings in diverse educational institutions. A qualitative multiple case study design was employed across six multicultural secondary schools in three countries, utilizing semi-structured interviews with 54 educators and focus group discussions with 120 students, analyzed through reflexive thematic analysis. Four design principles emerged as foundational to equitable hybrid learning: culturally responsive digital scaffolding, flexible multimodal content delivery, inclusive assessment architecture, and community-anchored technology integration. Institutions implementing all four principles demonstrated measurably higher student engagement and cross-cultural participation rates compared to partial-implementation counterparts. Intentionally designed hybrid learning frameworks that center cultural equity and pedagogical responsiveness can substantially reduce participation barriers and foster inclusive educational experiences across multicultural classroom contexts.
