The advancement of information technology has encouraged organizations to transform their data management practices, including those within the electrical power sector. PT PLN (Persero) UP3 Lubuk Pakam previously utilized Google Sheets to store and manage electrical energy loss data. However, this approach posed data security risks, as the files could be accessed and modified by unauthorized individuals. To overcome these limitations, this study developed a web-based information system specifically designed for the Electricity Energy Transaction Division (TEL) to replace Google Sheets as a platform for managing energy loss data. The proposed web application integrates a Role-Based Access Control (RBAC) mechanism, ensuring that only administrators are authorized to input, edit, or delete data, while other users can only view validated records. Furthermore, the system incorporates interactive data visualization through real-time charts, facilitating effective monitoring and analysis of electrical energy losses. The implementation of this system is expected to enhance data security, accuracy, and management efficiency within the TEL Division of PT PLN UP3 Lubuk Pakam.  

Right now, the utilization of data and correspondence innovation fundamentally affects different business areas, including producing. One arising idea is e-business, otherwise called electronic business. This idea underlines data exchanging and paperless exchanges through different innovations like Electronic Trade of Data (EDI), email, electronic notice sheets, electronic assets move, and other organization based propels. An e-business data framework is a gadget, innovation, or system that uses equipment, programming, organizations, and human insight to interface, do exchanges, and complete different hierarchical exercises without being restricted by time or area. The utilization of e-business data frameworks is a significant instrument that associations use to further develop business activities at the nearby and worldwide level. Indonesia is one of the trailblazers in web-based business and internet business. Nonetheless, the potential presented by e-business haven't completely taken advantage of by business affiliations.

Educational institutions are under pressure to create organized and responsible quality assurance systems because raising the standard of education has become a global imperative. The Internal Quality Assurance System (SPMI) and the External Quality Assurance System (SPME) are integrated in Indonesia to achieve this. However, accountability must be transparent, real-time, and not just administrative due to the quick digital revolution. In order to enhance educational accountability in the digital age, this study attempts to examine and model the integration of internet-based internal and external quality assurance systems. Nine pertinent papers from 2018 to 2025 were chosen and examined using a systematic Literature Review (LR) process and a qualitative methodology. The findings show that institutional performance and accountability are greatly improved by the successful implementation of SPMI, which is driven by the PPEPP cycle (Planning, Implementation, Evaluation, Control, and Improvement). Additionally, the integration of digital-based systems (e-SPMI) acts as a link between SPME and SPMI, guaranteeing data correctness, efficiency, and transparency for accrediting needs. The results highlight the need for an integrated, web-based quality assurance system that facilitates evidence-based decision-making in order to attain educational accountability in the digital age. In order to automate data collection and reporting procedures, the study advises educational institutions to implement an online quality management information system

CPU scheduling is a core function in modern operating systems that significantly impacts system performance and efficiency. Among various scheduling algorithms, Priority Scheduling is widely used and exists in two main variants: non-preemptive and preemptive. The non-preemptive mode allows a process to run to completion, while the preemptive mode can interrupt a running process for a higher-priority one. Understanding the behavioral differences between these modes is crucial but often challenging through manual calculations. To address this, an interactive web-based application was developed to simulate and visualize both preemptive and non-preemptive Priority Scheduling algorithms. The research method involved designing the system logic based on the core principles of each scheduling variant, followed by implementation using standard web technologies: HTML, Tailwind CSS, and JavaScript. The application allows users to input custom process data or load predefined case studies, select the scheduling mode, and instantly receive a comprehensive analysis. The results include a dynamically generated Gantt chart, a detailed performance metrics table (including turnaround time and waiting time), and a step-by-step execution log. Through a comparative analysis of a specific case study, the application is proven to be an effective educational tool. It accurately simulates both modes and visually demonstrates the impact of preemption on execution order, resource utilization, and key performance metrics, thereby simplifying the learning process for students and educators.

Moreover, by integrating digital solutions into governance, the system can contribute to strengthening the quality of education management and supporting better decision-making processes. Ultimately, the design of this information system demonstrates the potential of technology to transform public sector services and foster accountability in education governance.

Healthcare workforce management has become increasingly critical in determining organizational economic performance and long-term sustainability. This systematic review examines the relationship between human resource strategies in healthcare settings and their impact on economic outcomes, with particular attention to the effectiveness of workforce planning, recruitment optimization, employee retention, and performance management systems. The objective of this review is to synthesize current evidence on healthcare workforce management practices and their influence on economic performance indicators across various healthcare organizations. A systematic literature review was conducted using multiple academic databases, including PubMed, Scopus, and Web of Science. Studies published between 2019 and 2024 that focused on healthcare workforce management and its association with economic performance were selected based on predefined inclusion and exclusion criteria. A total of 45 peer-reviewed articles met the eligibility requirements and were included in the final analysis. The findings reveal that strategic human resource management practices significantly correlate with improved economic outcomes in healthcare organizations. Institutions implementing comprehensive workforce management approaches demonstrated a 15–25% improvement in cost-effectiveness, resource utilization, and operational efficiency. Moreover, effective healthcare workforce management was shown to directly enhance organizational performance by reducing staff turnover costs, improving employee productivity, and strengthening service delivery quality. This review concludes that integrated and evidence-based human resource strategies are essential for healthcare systems aiming to achieve sustainable economic growth and resilience in the face of evolving healthcare challenges.

This study proposes the integration of a Hybrid Recommendation method (combining Content-Based and Collaborative Filtering) with Random Forest Regression (RFR) to improve the accuracy of stay duration prediction in web-based boarding house booking systems. The main issue in online boarding booking systems is the inaccuracy of predicting user stay duration, affecting room allocation efficiency and customer satisfaction. The dataset was sourced from the hotel sector due to its attribute similarities and data validity. The research process includes data preprocessing (missing value imputation, normalization, and one-hot encoding), temporal and contextual feature engineering, hybrid recommendation system construction with CBF and CF score weighting, and RFR model training optimized through Grid Search and 10-fold cross-validation. Evaluation was conducted using MAE, RMSE, R² metrics, as well as recommendation metrics such as Precision@5, Recall@5, and Mean Reciprocal Rank (MRR). Results show that this integrated model achieved an R² of 0.7239 and an MAE of 1.0537 days, as well as a Precision@5 of 0.9636. This integration proves effective in improving prediction accuracy and recommendation relevance and contributes to the development of AI-based intelligent systems in the accommodation domain.
