Abstract

This study extends the Unified Theory of Acceptance and Use of Technology (UTAUT) to explain why citizens frequently abandon digital public services despite substantial government investment in e‑government platforms. It focuses on Riau Province, Indonesia, and positions User Satisfaction as a central mediator linking four UTAUT antecedents—Performance Expectancy, Effort Expectancy, Social Influence, and Facilitating Conditions—to actual usage behavior. Adopting a deductive quantitative design, the research uses a stratified random survey of 240 e‑government users and analyzes the data with PLS‑SEM, supported by rigorous tests of reliability, validity, common‑method bias, and predictive relevance. The model explains 80.1% of the variance in User Satisfaction and 80.2% in User Behavior, indicating strong explanatory and predictive power. Results show that Performance Expectancy, Social Influence, and Facilitating Conditions significantly increase satisfaction, while Performance Expectancy, Facilitating Conditions, and User Satisfaction itself are key direct predictors of continued use. User Satisfaction also mediates the effects of performance expectancy, social influence, and facilitating conditions on behavior. Although Effort Expectancy is not statistically significant at the 5% level, it exhibits the largest effect size on satisfaction, underscoring the structural importance of ease of use. Theoretically, the study validates an under‑explored affective pathway in mandatory settings; practically, it offers a roadmap for shifting from technology‑centric to citizen‑centric digital governance.

Abstract

CCTV facial images often suffer from poor quality due to low resolution, motion blur, and poor illumination, complicating forensic investigation and identification. This situation necessitates more modern image restoration methods. This study proposes a Generative Adversarial Network (GAN)-based pipeline that combines two architectures, Real- ESRGAN for resolution enhancement and GFPGAN for more natural facial feature recovery. Experimental results show significant improvements in perceptual quality with a decrease in NIQE values from 12.56 to 7.81 and BRISQUE from 70.81 to 44.23, with an 82% image recovery success rate. Additional evaluations using texture entropy and gradient histograms demonstrate consistency in facial structure and edge sharpness. This study contributes by demonstrating an integrated two- stage GAN approach as an effective solution for face recovery in low-quality CCTV images, while highlighting the need for standardized forensic protocols and facial identity validation in real-world applications. Thus, this pipeline can serve as a pre-processing stage to improve image readability and has the potential to be used as a tool for forensic investigations.

Abstract

The convergence of the Internet of Things (IoT) and Society 5.0 has successfully led to a human-centered and data-driven life ecosystem. IoT has become the backbone for infrastructure implemented in various domains, ranging from smart homes and smart farming to smart industrial environments. Nevertheless, as IoT devices become more connected and integrated into the ecosystem, the attack surface expands and network security becomes more challenging. The massive convergence and connectivity of IoT devices have a high potential for attacks on network infrastructure, such as Denial of Service (DoS), port scanning, exfiltration, brute force, and man-in-the-middle attacks. This study aims to detect anomalies in IoT network traffic by applying the Isolation Forest (IF) algorithm. The dataset was obtained from an IoT gateway connected to smart home devices and includes features such as data packet size, connection duration, source and destination capacity, attack protocols used, and the connection status of each device. The experimental results of this study indicate that the IF method can identify smart home device attacks with a competitive level of accuracy. The results of the anomaly analysis are then presented through a confusion matrix, classification report, and analytical visualizations such as 2D PCA, t-SNE, heatmap, and temporal distribution of anomalies. This study declares that the IF method contributes effectively to the analysis of Intrusion Detection Systems (IDS) in IoT environments such as smart homes that are heterogeneous and dynamic

Abstract

The diversity of non-verbal communication styles among persons with disabilities in Indonesia highlights the urgent need for technological solutions that support accessibility in both workplace settings and social contexts. This study proposes a novel approach to improving neural network performance through the use of simple architectures for recognizing Indonesian Sign Language (SIBI) letters M and N, by applying keypoint detection while accounting for hand size variations (17–22 cm). Four models were evaluated: YOLOv5 based on image detection, as well as VGG-16, Attention, and Multi-Layer Perceptron (MLP) developed using keypoint detection. The evaluation was conducted in real-time, taking into account accessories such as rings, watches, and gloves, as well as varying lighting intensities to simulate real-world user environments. The novelty lies in the integration of keypoint detection into lightweight architectures, which significantly improves accuracy and resilience against visual disturbances (noise). The MLP model achieved the best performance, with an accuracy of 94% for M and 93% for N, outperforming more complex approaches such as YOLOv5, which showed a significant drop in accuracy under disturbed conditions. The integration of VGG-16 with Attention resulted in underfitting, emphasizing that complexity does not always correlate with effectiveness. These findings underscore the potential of lightweight models to enhance technological accessibility for the disabled community across various social and professional domains.

Abstract

This study examines profit-sharing practices at Koperasi Insan Madani Syariah in Rantau Karya Village and evaluates their conformity with Sharia economic law. Motivated by the need for equitable Islamic economic arrangements as alternatives to interest-based mechanisms, the research aims to identify how profit-sharing is operationalized and to assess its legal-normative alignment. Employing a qualitative phenomenological approach, data were collected through in-depth interviews, participant observation, and document analysis involving cooperative managers, members, and community leaders. Findings indicate that the cooperative implements profit-sharing primarily through mudharabah mutlaqah and syirkah al-inan arrangements, distributing residual income proportionally based on members’ capital contributions and transactional participation; transparency and annual deliberations reinforce member trust, while gaps remain in members’ technical understanding of nisbah calculations. The study contributes theoretically by explicating how distributive justice principles under Sharia manifest in micro-cooperative settings and offers practical insights for improving governance, member education, and accountability in Sharia microfinance institutions. The results provide an empirical reference for practitioners and policymakers seeking to strengthen Sharia-compliant profit-sharing mechanisms at the grassroots level.
