Abstract

Anxiety disorders among adolescents have become a growing concern, with increasing cases linked to academic pressure, social expectations, and digital media exposure. Conventional treatments often rely on pharmacological and psychological interventions; however, alternative therapies such as dhikr (Islamic remembrance of God) are gaining attention for their potential psychological benefits. Rooted in Islamic spiritual practices, dhikr therapy is believed to induce a calming effect, promote mindfulness, and enhance emotional regulation. Understanding its effectiveness in alleviating anxiety among adolescents can contribute to integrative mental health approaches. This study aims to evaluate the impact of dhikr therapy on reducing anxiety symptoms in adolescent patients through a structured intervention program. A quasi-experimental research design was employed, involving 60 adolescent patients diagnosed with anxiety disorders. Participants were divided into an intervention group receiving guided dhikr therapy and a control group undergoing standard anxiety management. Anxiety levels were measured using the Generalized Anxiety Disorder Scale (GAD-7) before and after the intervention. Findings indicate a significant reduction in anxiety scores among participants in the dhikr therapy group compared to the control group. The study concludes that dhikr therapy serves as an effective complementary approach in managing adolescent anxiety. Recommendations for integrating dhikr therapy into holistic mental health programs are discussed.

Abstract

Corporate governance plays a pivotal role in ensuring transparency and accountability in financial reporting, particularly in mitigating earnings management practices. Earnings management, which involves the manipulation of financial statements to present a desired image, undermines the reliability of financial information. In Indonesia, where corporate governance practices are still evolving, understanding the relationship between corporate governance and earnings management is critical for improving financial reporting quality. This study aims to examine the impact of corporate governance mechanisms on earnings management practices in public companies listed on the Indonesia Stock Exchange (IDX), providing insights into how governance structures can deter manipulative financial reporting. A quantitative research design was employed, utilizing data from 150 public companies listed on the IDX over a five-year period (2017-2021). Multiple regression analysis was used to analyze the relationship between corporate governance variables (e.g., board independence, audit committee effectiveness) and earnings management, measured using discretionary accruals. The findings reveal that stronger corporate governance mechanisms, particularly board independence and audit committee effectiveness, significantly reduce earnings management practices. Companies with higher governance scores reported lower levels of discretionary accruals, indicating more transparent financial reporting. This study highlights the importance of robust corporate governance in curbing earnings management.

Abstract

The rapid integration of artificial intelligence (AI) into educational settings has outpaced the development of clear ethical guidelines, creating significant challenges related to academic integrity, data privacy, and algorithmic bias. Understanding stakeholder attitudes is crucial for developing effective policies for responsible AI use. This study aimed to empirically investigate and compare the attitudes of high school students and teachers regarding the ethical challenges and responsible use of AI in education. A mixed-methods approach was employed, using a quantitative survey administered to 250 students and 50 teachers to gauge attitudes toward AI ethics. This was supplemented by qualitative data from semi-structured focus groups to explore the reasoning behind these attitudes. The findings revealed a significant divergence in attitudes, with teachers expressing greater concern for academic integrity and data privacy, while students were more focused on AI as a tool for efficiency. Both groups, however, demonstrated a shared desire for clear, explicit ethical guidelines. A notable gap exists between student and teacher perspectives on AI ethics in education. To foster a culture of responsible AI use, educational institutions must implement comprehensive training and develop clear policies that address the distinct concerns of both stakeholder groups.

Abstract

The digital revolution has profoundly reshaped the landscape of religious authority and practice in the Muslim world, challenging traditional clerical hierarchies. In Indonesia, the authority of the ulama, long central to the dissemination of Islamic knowledge, now coexists with a vibrant and often unregulated digital sphere. This study aimed to investigate how digital media is reconfiguring traditional Islamic authority and influencing the religious practices of Indonesian Muslims. The primary objective was to analyze the strategies employed by both traditional ulama and new digital religious figures in this evolving media ecosystem. A qualitative methodology was employed, combining digital ethnography of popular religious social media platforms with in-depth, semi-structured interviews with established ulama and emergent "cyber-preachers." The results reveal a significant fragmentation and democratization of religious authority. New media figures are leveraging platforms like YouTube and Instagram to bypass traditional institutions, offering direct religious guidance to a mass audience. In response, many traditional ulama are adapting by creating their own digital presence, yet often struggle to match the popular appeal of these new influencers. This study concludes that digital media is fostering a more contested, personalized, and networked religious landscape in Indonesia. This reconfiguration is not replacing the traditional ulama but is forcing them into a new, competitive role, fundamentally altering how religious authority is constructed, consumed, and maintained in the digital age.

Abstract

Contemporary architecture in many Islamic countries faces the dual challenge of preserving cultural identity while addressing energy efficiency and thermal comfort in harsh climatic conditions. This research explores the integration of modular construction with the timeless principles of Islamic architecture and the use of indigenous, climate-responsive materials as a sustainable solution. A prototype of a modular residential unit was designed, incorporating key Islamic architectural elements such as a central courtyard, mashrabiya (ornate lattice screens), and strategic orientation. The design utilized locally sourced materials with high thermal mass, such as rammed earth and reclaimed timber. The thermal performance was rigorously evaluated using computational fluid dynamics (CFD) and dynamic thermal simulations with EnergyPlus software. The simulation results were benchmarked against a conventional modern residential unit of equivalent size. The integration of passive design strategies resulted in a 25% reduction in annual cooling loads. Indoor operative temperatures remained within the comfort zone for 60% longer than the baseline case, substantially minimizing reliance on mechanical air conditioning. The mashrabiya and courtyard proved effective in facilitating natural ventilation and reducing solar heat gain. This study validates that merging modular construction with climate-responsive local materials and Islamic architectural wisdom offers a viable path toward sustainable and culturally resonant architecture.

Abstract

The increasing presence of persistent pharmaceutical contaminants in water bodies poses a significant threat to environmental and human health, necessitating effective remediation technologies. This study aimed to develop and evaluate zinc oxide/copper oxide (ZnO/CuO) composite thin films as an efficient photocatalyst for degrading pharmaceutical waste under visible light. The ZnO/CuO thin films were synthesized via a sol-gel spin-coating method, and their photocatalytic activity was assessed using diclofenac as a model pollutant. The results demonstrated that the ZnO/CuO heterostructure exhibited enhanced visible light absorption and superior photocatalytic performance compared to pure ZnO. The composite films achieved over 90% degradation of diclofenac within 120 minutes, with the process following pseudo-first-order kinetics. The enhanced efficiency is attributed to effective charge separation at the ZnO/CuO interface. This research confirms that ZnO/CuO thin films are promising, reusable photocatalysts for the sustainable treatment of pharmaceutical-contaminated water.

Abstract

Cervical cancer remains a leading cause of mortality among women worldwide, primarily due to challenges in early and accurate detection. Conventional screening methods like Pap smears are subject to human error and have moderate sensitivity. This study aimed to develop and validate a novel, non-invasive diagnostic platform combining Raman spectroscopy with artificial intelligence (AI) for the rapid and highly accurate detection of early-stage cervical cancer biomarkers. The objective was to create a system that could overcome the limitations of current screening techniques. We collected cervical cell samples from clinically diagnosed healthy, pre-cancerous (CIN I-III), and cancerous patients. Raman spectroscopy was used to acquire high-resolution biochemical fingerprints from these samples. A custom-developed convolutional neural network (CNN) was then trained on the spectral data to learn and identify subtle biomarker-associated patterns indicative of neoplastic transformation. The AI-augmented system achieved a diagnostic accuracy of 96.5%, with a sensitivity of 98% and a specificity of 95% in differentiating high-grade lesions and cancerous samples from healthy ones. The model successfully identified key spectral shifts related to nucleic acid and protein conformational changes, correlating them with disease progression.
