The Fréchet distribution is one of the commonly used Extreme Value Distributions (EVDs) in statistical modeling and heavy-tailed data analysis, where it plays an important role in describing product lifetimes as well as climatic and financial phenomena. The estimation of its two parameters, namely the shape parameter and the scale parameter, is traditionally based on the Maximum Likelihood Estimation (MLE) method. However, maximizing the likelihood function for this distribution involves numerical difficulties, which necessitates the use of numerical optimization methods. In this study, we propose the use of the Aquila Optimizer (AO), a recent metaheuristic algorithm inspired by the hunting behavior of eagles, as an efficient numerical tool for maximizing the likelihood function of the Fréchet distribution. The objective function was formulated as the negative log-likelihood function (-LogL), and the Aquila Optimizer was employed to obtain the optimal estimates of the distribution parameters. Several simulation experiments with different sample sizes were conducted to compare the performance of the proposed method with a conventional approach represented by the Nelder–Mead method, using the Mean Squared Error (MSE) criterion. The simulation results demonstrated that the Aquila Optimizer outperformed the Nelder–Mead algorithm in many cases, although the superiority was slight. The results also showed that both algorithms were consistent, as their MSE values decreased with increasing sample size. In addition, a practical application was carried out using real data, and the results of the survival function estimation indicated a good fit.

Healthcare institutions worldwide are undergoing digital transformation to improve efficiency and patient experiences. While many studies focus on clinical applications of information technology (IT), its impact on administrative service quality remains limited, even though administrative services are patients’ primary point of contact. This study examines how IT adoption influences administrative service quality in Indonesian healthcare institutions, focusing on relationships between IT implementation levels and service quality dimensions, as well as mediating and moderating factors. Using a mixed-methods sequential explanatory design, quantitative data were collected from 385 patients and 127 administrative staff across 24 hospitals, supported by 32 in-depth interviews. Service quality was measured using SERVQUAL dimensions: tangibles, reliability, responsiveness, assurance, and empathy. The findings show significant positive relationships between IT adoption and all service quality dimensions, with the strongest effects on reliability and responsiveness. Staff digital competency and system usability partially mediate these relationships, while implementation quality acts as a key moderating factor. Well-implemented systems yield substantially higher service improvements than poorly implemented ones. Most patients prefer digital services when functioning properly, although many report frustration when systems fail or staff lack competency. This study highlights the importance of effective IT implementation to enhance administrative service quality and offers practical insights for healthcare management.

Leadership constitutes a critical determinant of organizational efficiency, yet the relationship between leadership styles and administrative effectiveness remains incompletely understood, particularly across different institutional contexts. This comparative study examines how transformational, transactional, and laissez-faire leadership styles influence administrative efficiency in public and private sector institutions in Indonesia. Using a mixed-methods approach, quantitative data were collected from 428 employees across 28 public institutions and 24 private organizations through validated survey instruments; qualitative data were gathered through 36 semi-structured interviews with organizational leaders and managers. Results reveal significant positive relationships between transformational leadership and administrative efficiency in both sectors (β = 0.54, p < 0.001 for public; β = 0.48, p < 0.001 for private), with transactional leadership showing moderate positive effects (β = 0.32 public; β = 0.38 private) and laissez-faire leadership demonstrating negative relationships (β = −0.28 public; β = −0.24 private). Leadership styles collectively explain 52% of efficiency variance. Mediation analysis reveals that organizational culture (28%), employee engagement (35%), and trust in leadership (22%) partially mediate transformational leadership's effects, together accounting for 62% of total indirect effects. Sector differences emerged qualitatively: transformational leadership leverages public service motivation in public institutions, while transactional leadership's performance accountability resonates more strongly in private organizations. The study contributes theoretical understanding of leadership effectiveness across institutional contexts and provides practical guidance for developing contextually appropriate leadership development programs.

Manufacturing accounts for about 28.9% of global final energy use, making inefficient operations a major source of cost and greenhouse gas emissions. This review synthesizes how artificial intelligence supports energy optimization within Industry 4.0-enabled manufacturing systems. It organizes methods into four families: machine learning for forecasting and anomaly detection, deep learning for nonlinear and temporal modelling, reinforcement learning for adaptive scheduling and real-time control, and metaheuristics for balancing energy, throughput, and quality objectives. Applications span plant-level demand prediction and peak management, shop-floor rescheduling under dynamic pricing, equipment-level optimization through predictive maintenance, and system-wide planning using digital twins and cyber-physical integration. Reported benefits include lower energy costs, reduced downtime, improved productivity, and progress toward decarbonization. However, large-scale deployment is constrained by poor data quality and interoperability across IIoT, MES, ERP, and EMS platforms, high implementation and computational costs, skills gaps, and weak governance and benchmarking standards. Emerging solutions include federated learning and edge AI for privacy-preserving, low-latency analytics, explainable AI to enhance trust and auditability, tighter smart-grid integration, and circular economy-driven optimization. The review concludes with practical priorities for reliable, transparent, and scalable AI-enabled energy management.

The digital transformation of public administration represents a critical pathway toward modernizing governance, enhancing service delivery, and improving transparency in Indonesian government agencies. This study examines the current state of digital transformation initiatives across various levels of government in Indonesia, identifying key challenges and opportunities in implementing digital technologies within bureaucratic structures. Through a convergent parallel mixed-methods design combining surveys of 245 government officials from 32 agencies and in-depth interviews with 28 digital transformation leaders, this research reveals that while Indonesian government agencies have made significant progress, substantial barriers remain including limited digital infrastructure in remote regions, resistance to organizational change, insufficient digital literacy among civil servants, and inadequate legal frameworks. The overall mean maturity score was 2.87 (SD = 0.74), placing the average agency in the 'developing' category, with only 6% reaching the 'optimizing' level. The study identifies critical success factors: strong leadership commitment (β = 0.38, p < 0.001), citizen-centric design, comprehensive change management, and effective public-private partnerships. Findings indicate that successful digital transformation requires not merely technological adoption but fundamental organizational restructuring and cultural shifts toward data-driven decision-making and collaborative governance. Policy recommendations address digital infrastructure investment, human capital development, governance reform, and shared platform utilization. This research contributes to theoretical understanding of digital government in developing nations and provides practical guidance for policymakers navigating the complexities of public sector digitalization.

Gerakan Tutup Mulut (GTM), or “Refusal to Eat,” is a common nutritional problem among toddlers and contributes to reduced nutrient intake and an increased risk of malnutrition. Preliminary observations at Posyandu Aster 11 Way Kandis, Bandar Lampung, indicated that mothers had low levels of knowledge regarding the causes of GTM and limited exposure to responsive feeding education. This community service activity aimed to improve mothers’ understanding of the factors contributing to GTM and to introduce pisang barongko as an innovative, nutritious snack option to help prevent GTM. The methods utilized included educational sessions through leaflets, presentations, video demonstrations, and pretest–posttest evaluation using the Wilcoxon test. The activity involved 25 participants and resulted in an improvement in knowledge scores from an average of 66 to 94.8, demonstrating a significant increase of 28.80 (p < 0.05). High participant enthusiasm, effective material delivery, and the availability of educational outputs such as videos and leaflets supported the success of the program. These findings highlight the importance of nutrition education based on local food resources as a practical and sustainable strategy to prevent GTM in children.

Difficulties in learning to read the Qur’an among adults do not always stem from the quality of teaching materials or instructors, but are often caused by the use of learning methods that are not appropriate to adult learners’ characteristics. Adults possess distinct psychological, physiological, and experiential backgrounds that require learning approaches different from those used for children. Monotonous and rigid instructional methods may hinder motivation and limit learning outcomes, particularly in Qur’anic literacy education. This condition is further compounded by physical limitations commonly experienced by adults and the elderly, such as dental and oral health problems, as well as strong regional language accents that affect pronunciation accuracy. In response to these challenges, the Tsaqifa method was developed as an alternative and practical approach specifically designed for adult beginners who have little or no prior ability to read the Qur’an. This method emphasizes simplicity, flexibility, and learner-centered instruction, enabling participants to gradually improve their Qur’anic reading skills in a supportive and non-intimidating learning environment. Through its application, adult learners are encouraged to regain confidence and motivation in studying the Qur’an, thereby contributing to efforts to reduce Qur’anic illiteracy among adult and elderly communities, particularly in rural areas.

The subjects were seventh-grade students at SMPN 9 Pasuruan. Data collection techniques used validation sheets, practicality questionnaires, and learning outcome tests. Data analysis was conducted using descriptive, quantitative, and qualitative methods. The results showed that validation from material experts and media experts achieved an average score of 91.88%, categorized as very valid. Practicality based on teacher and student responses achieved an average score of 91.42%, categorized as very practical. The results of the learning outcome test (posttest) showed an average score of 85, categorized as effective. Thus, the mathematics learning media based on the 24 Game UNO card game is declared valid, practical, and effective for use in the learning process.  

This study aims to analyze the role of Islamic Religious Counselors as street-level bureaucrats in implementing Islamic Community Guidance policies in Batang Regency. The study used a mixed-methods approach with a sequential explanatory design, beginning with the collection and analysis of quantitative data and then deepening with qualitative data. Quantitative data were obtained from 53 respondents using a questionnaire that was tested for validity and reliability. In contrast, qualitative data were collected through in-depth interviews, observations, and documentation with religious counselors, Ministry of Religious Affairs officials, the KUA (Office of Religious Affairs), and the community. Data analysis was conducted descriptively and analytically using Michael Lipsky's street-level bureaucracy theory as an analytical framework. The study's results indicate that the role of Islamic Religious Extension Workers as street-level bureaucrats is positively and strongly associated with the successful implementation of the Islamic Community Guidance policy (r = 0.826; p < 0.01). Qualitative findings revealed that extension workers exercise discretion in the form of community assistance, adjustments to extension methods, strategic flexibility, and responsiveness to socio-religious issues at the local level. This study confirms that the effectiveness of Islamic Community Guidance policies is not determined solely by formal policy design but is highly dependent on the capacity, flexibility, and discretion of Islamic Religious Counselors, the implementing actors at the field level. These findings provide theoretical contributions to the development of street-level bureaucracy studies in the context of religious policy, as well as practical implications for formulating more contextual and responsive policies.

This study aims to analyze the influence of digitalization on the lifestyles of students at Universitas Nasional Pasim. The research employs a quantitative approach through field survey methods, targeting a population of 123 students from the Faculty of Economics, Class of 2025. A minimum sample size of 56 respondents was determined using the Slovin formula.

This study explores the integration of community driven learning practices in the adoption of educational technology and its impact on sustainability. With the rapid advancement of digital tools and platforms, higher education institutions have increasingly adopted online and hybrid learning models to enhance teaching and learning. However, despite the potential benefits, aligning institutional goals with community needs remains a significant challenge. This research utilizes a mixed methods approach, combining stakeholder surveys, policy analysis, and comparative case studies to evaluate the effectiveness of both top down and community aligned adoption models. The findings reveal that community driven models, which involve local stakeholders in the decision making process, lead to higher engagement, better adoption rates, and greater long term sustainability compared to top down approaches. Stakeholders, including educators, students, and administrators, reported that participatory decision making fostered a sense of ownership and ensured the relevance of adopted technologies. The study also identifies key sustainability factors, including participatory decision making, long term community engagement, and contextual relevance, which are crucial for ensuring that educational technologies remain effective and beneficial over time. However, challenges such as resistance to change, lack of resources, and unequal access to technology were found to hinder the successful implementation of sustainable models. The research concludes with practical recommendations for educational institutions and policymakers to adopt community aligned models and ensure equitable access to technology. Future research directions are suggested to further explore the balance between institutional innovation and community driven learning, with a focus on long term outcomes and the adaptability of these models across different educational contexts.

Background: Suboptimal breast milk production during the postpartum period remains a major barrier to successful exclusive breastfeeding. Various non-pharmacological interventions have been developed to address this issue, including oxytocin massage, which is believed to stimulate the release of the oxytocin hormone and facilitate milk ejection. However, findings regarding its effectiveness remain varied, highlighting the need for a comprehensive synthesis of scientific evidence. Objective: This study aims to review and synthesize evidence on the effectiveness of oxytocin massage in increasing breast milk production among postpartum mothers. Methods: A literature review with a narrative review approach was conducted using articles from Google Scholar, PubMed, and Garuda databases published between 2021 and 2025. Keywords included oxytocin massage, breast milk production, and postpartum mothers. Inclusion criteria were original research articles involving postpartum mothers receiving oxytocin massage interventions with full-text access. Article selection followed the PRISMA flow, resulting in 12 eligible studies analyzed narratively. Results: Most studies reported that oxytocin massage improves breast milk production and milk flow, indicated by increased milk volume, improved let-down reflex, higher breastfeeding frequency, and adequate infant intake. The effect is associated with parasympathetic stimulation that promotes oxytocin release and maternal relaxation. Conclusion: Oxytocin massage is a safe and practical complementary intervention to support breast milk production, although further studies with stronger experimental designs are needed.

Therefore, further research is recommended to broaden the scope, incorporate public service quality variables, and use a longitudinal design to examine the long-term impact of archive digitisation on the performance of bureaucratic reform and digital governance more comprehensively. These findings also provide practical contributions for local governments in designing integrated, sustainable electronic archive management policies that support effective, transparent, and responsive public services to meet the needs of modern society in the future, as well as strengthening data-driven governance.  

Background: In the competitive healthcare landscape, where human resources are pivotal to organizational success, affective commitment defined as emotional attachment to the workplace is essential for nurse retention and service quality. Satya Negara Hospital in North Jakarta exemplifies the challenges faced by Indonesian healthcare institutions, with a notably high nurse turnover intention of 30% in 2024, signaling low affective commitment and underscoring the urgency to identify its drivers. While person-job fit and career development are established antecedents of commitment, their combined influence within Indonesia’s nursing context, along with the potential moderating role of meritocracy, remains underexplored.. Methods:  Using a quantitative, cross sectional design, data were collected via a validated questionnaire from all 108 nurses at the hospital and analyzed using multiple regression.. Results: The results revealed that person-job fit, career development, and meritocracy collectively explain 96.6% of the variance in affective commitment. Furthermore, when meritocracy was tested as a moderating variable, the explanatory power of the model increased significantly, with the adjusted R² value rising from 96.6% to 98.5%. This indicates that the presence of a meritocratic system substantially amplifies the positive effects of both person-job fit and career development on commitment.. Conclusion: The study concludes that a synergistic combination of job fit, growth opportunities, and a merit-based system is fundamental to fostering nurses’ emotional attachment. These findings contribute to organizational and psychological theory integration and offer practical human resource strategies for enhancing nurse commitment and reducing turnover in healthcare settings.
