Abstract

The phenomenon of female converts marrying under the guardianship of religious leaders in Batu Ampar District presents a unique issue, as it does not entirely align with national legal procedures, yet enjoys broad acceptance within the local community. While earlier studies have focused on court-appointed guardians (wali hakim) or the role of wali muhakkam in emergencies, limited research has analyzed this phenomenon through the lens of hearing shari'ah. This study seeks to address that gap by exploring the underlying factors, examining the validity of the marriage process according to classical Islamic jurisprudence, and interpreting it through the objectives of Islamic law. Using a qualitative descriptive method, data were collected through interviews and field observations. The findings reveal that the factors prompting the use of religious leaders as marriage guardians include the absence of a Muslim lineage guardian, economic limitations in accessing formal legal procedures, social pressure to maintain family honour, and the high legitimacy of religious leaders within the community. From the perspective of fiqh procedures, the marriage fulfilled all the essential pillars and conditions, such as the presence of acceptance (offer and acceptance), two just witnesses, a guardian (still), and a dowry (mahar). From the viewpoint of maqashid syari’ah, the marriage achieved the protection of religion (hifzh al-din), life (hifzh al-nafs), honor (hifzh al-‘ird), lineage (hifzh al-nasl), and property (hifzh al-mal).

Abstract

Penelitian ini bertujuan untuk menguji pengaruh Leader-Member Exchange (LMX) terhadap kinerja karyawan dengan self-efficacy sebagai variabel intervening pada PDAM Kabupaten Dompu. Menggunakan metode kuantitatif dengan pendekatan kausal, penelitian ini melibatkan sampel sebanyak 30 responden dari total 48 karyawan, yang dipilih melalui simple random sampling. Data primer dikumpulkan melalui kuesioner dan dianalisis menggunakan Structural Equation Modeling (SEM) berbasis PLS. Hasil analisis menunjukkan bahwa LMX berpengaruh positif dan signifikan terhadap self-efficacy, dan self-efficacy juga terbukti berpengaruh positif dan signifikan terhadap kinerja karyawan. Namun, penelitian ini tidak menemukan adanya pengaruh langsung yang signifikan dari LMX terhadap kinerja karyawan. Sebagai temuan utama, self-efficacy terbukti berperan sebagai mediator penuh (full mediation) yang signifikan dalam hubungan antara LMX dan kinerja karyawan. Kesimpulan ini menegaskan bahwa pengaruh LMX terhadap kinerja tidak terjadi secara langsung, melainkan harus melalui peningkatan keyakinan diri karyawan terlebih dahulu. Temuan ini memberikan implikasi penting bagi PDAM Kabupaten Dompu untuk memperkuat pola kepemimpinan yang suportif guna membangun self-efficacy sebagai kunci utama peningkatan kinerja.

Abstract

This research brings to light an urgent dilemma pervading the broadband service supplying sector exemplified by PT. Faznet.Presently, clients have difficulties effectively communicating interruptions owing to manual processes providing scant network performance information. Addressing this communication vacuum, we propose a wireless network monitoring web portal engineered to dynamically present internet conditions in real time (speed, signal quality, status) and enable two-way interactions through disturbance reporting, maintenance advisories, and status updates. The developmental approach applies the Unified Modeling Language (UML), starting with Use Case Diagrams to model user requirements, progressing to Activity Diagrams detailing work processes, Sequence Diagrams sequencing intercomponent operations, and lastly Class Diagrams outlining software structure. It is expected that implementing this system will notably amplify transparency and responsiveness to better serve customers of PT. Faznet. This paper investigates a key challenge in sharing network performance data and service issues with subscribers of an internet provider. The suggested remedy involves designing an online dashboard displaying current network metrics and a feedback mechanism for users and technicians to exchange information on problems, repairs, and network status. System architecture and evolution adheres to modeling best practices to map workflows, message passing, and class relationships with the goal of vastly improving availability of network intelligence to customers while strengthening support reactivity. This aims to boost satisfaction levels among the user base of the featured broadband corporation.

Abstract

This study explores the optimization of reserve prices in real-time first price auctions within digital advertising using decision tree and random forest algorithms. The dataset used includes 567,291 entries covering various variables such as impressions, bids, prices, and revenue, providing a comprehensive view of auction dynamics over a full year. The decision tree model achieved a Mean Squared Error (MSE) of 0.1347 and an R² score of 0.731, indicating a reasonable level of accuracy in predicting reserve prices. In contrast, the random forest model significantly outperformed the decision tree model with an MSE of 0.0789 and an R² score of 0.842, demonstrating superior predictive power and robustness. The analysis revealed that the application of these machine learning models significantly enhances the accuracy and reliability of reserve price predictions, helping publishers to optimize their revenue. The findings show that by setting optimal reserve prices based on the models' predictions, publishers can minimize the risk of underselling ad inventory and maximize revenue, as evidenced by a 15% increase in revenue observed in a case study after implementing the random forest model. The study also provides insights into bidder behavior, particularly bid shading strategies, highlighting how bidders adjust their bids in response to different reserve price settings. Higher reserve prices tend to reduce bid shading, resulting in more competitive and balanced auctions. The practical implications for digital marketing include enhanced strategic decision-making for publishers and a more transparent and predictable bidding environment for advertisers. Despite the promising results, the study acknowledges limitations such as reliance on historical data from a single ad exchange platform and the assumptions inherent in the models. Future research should expand the dataset to include multiple platforms and explore more advanced machine learning techniques to further improve reserve price optimization. Overall, this research underscores the potential of leveraging data science and machine learning to transform digital advertising strategies, driving higher revenue and efficiency in the industry.

Abstract

This study investigated the role of trust (TR) in mediating the impact of electronic word of mouth (EW) and security (SE) on cryptocurrency purchase decisions (PD). A cross-sectional survey design was employed, and data were collected through 330 distributed questionnaires, of which 320 valid responses were retained after validation steps that included confirming prior cryptocurrency usage. The sample consisted of active cryptocurrency users in Indonesia, aiming to explore the relationships between EW, SE, attitudes (AT), perceived behavioral control (PB), TR, and PD. Structural equation modeling was used to analyze the data and test the hypothesized relationships. The findings highlighted that TR significantly mediated the effects of both EW and SE on PD, underscoring TR as a crucial factor in the cryptocurrency market. Additionally, the study revealed that PB played a significant role, particularly in mediating the relationship between SE and PD, suggesting that consumers' confidence in managing transactions greatly influences their purchasing behavior. The results contribute to the literature by validating an integrated model that combines key factors influencing cryptocurrency PD and extending the Theory of Planned Behavior by incorporating EW and SE as antecedents. The study provides practical implications for cryptocurrency platforms and marketers, emphasizing the need for robust security measures, positive EW management, and user-friendly interfaces to foster TR and enhance consumer engagement in the cryptocurrency market.

Abstract

This study explored the adoption of metaverse platforms in Indonesian corporations through a moderated model integrating Self-Determination Theory and the Technology Acceptance Framework. Data were collected from 355 respondents through a structured questionnaire, of which 344 were deemed valid after a validation step confirming prior use of metaverse platforms. The research focused on understanding the factors influencing Usage Intention (UI) by examining the roles of Customization Capability (CUS), Immersive Experience Features (IMF), Social Influence (SOC), and Technology Reliability (TR) on Perceived Usefulness (PU). The results indicated that CUS, IMF, and TR significantly enhanced PU, which was a strong predictor of UI, underscoring the critical mediating role of perceived usefulness in driving adoption. The findings revealed that customization and reliability were pivotal in enhancing perceived utility, while the impact of immersive features, though positive, was less pronounced. SOC had a modest effect on UI, suggesting that direct functional benefits of the platform were prioritized by users over peer validation. The study contributed to the literature by providing an integrated model that highlights the importance of both individual and contextual factors in technology adoption within corporate environments. Practical implications suggest that corporations should focus on developing customizable, reliable, and functionally beneficial metaverse platforms to foster sustained adoption.
