Abstract

Analisatoday.com is a leading news portal focusing on political, economic and social issues. This portal aims to provide media solutions for public leaders and political figures in publicizing their activities and activities more effectively and professionally. By promoting the principles of transparency and information disclosure, Analisatoday.com plays an important role in delivering information about the work programs, visits, meetings, and activities of leaders to the public. In the process of news publication, the use of technology has grown, including in terms of data collection and information management. However, the news data collection system at Analisatoday.com is still not optimal. Currently, the data collection process is still mixed with news uploading activities, and is less efficient and not well organized. In addition, the lack of user understanding of the existing system is also an obstacle. To overcome these problems, the author designed a web-based journalist news data collection application using the Scrum method. This system is designed to be simpler, more efficient, and accurate in supporting the work process of journalists. Through this application, journalists can collect, verify, and manage news data in an integrated manner. With website-based technology and the utilization of PHP and MySQL as tools, this system is expected to improve  performance  and  effectiveness  in  managing  news  data  in Analisatoday.com.

Abstract

Musculoskeletal disorders (MSDs) are a major occupational health problem worldwide. Batik workers are considered a high-risk group due to exposure to static work postures, repetitive movements, and long working hours. Purpose: This study aimed to identify the factors contributing to musculoskeletal complaints among batik workers in the Keraton district. Methods: A descriptive mixed-methods design was employed. Qualitative data were collected through in-depth interviews with three batik workers and analyzed using content analysis with the assistance of OpenCode software. Quantitative data were obtained through work posture observation using the Rapid Entire Body Assessment (REBA) method to assess ergonomic risk levels. Results: Interviews revealed complaints of pain in the shoulders, arms, knees, calves, thighs, ankles, neck, right elbow, waist, and back. Identified risk factors included age, duration of work, physical activity, overtime, and insufficient rest. REBA analysis showed scores of 7–9, indicating high risk requiring immediate intervention. Integration of qualitative and quantitative findings reinforced that batik activities impose repetitive strain on the musculoskeletal system.. Conclusion: Batik workers face a high risk of musculoskeletal disorders without adequate occupational health protection. Ergonomics-based interventions, occupational health education, and improvements in the work environment should be implemented promptly.

Abstract

This study successfully implemented the K-Means Clustering algorithm to map students’ library visit interest patterns at the STMIK Methodist Binjai Library. The clustering results were empirically validated using a Silhouette Coefficient score of 0.8304, with the optimal number of clusters determined as k = 3 through the Elbow Method. The clustering process identified three strategic profiles: a Low-Interest Cluster consisting of 117 students with an average of 1.50 visits, a Moderate-Interest Cluster comprising 19 students with an average of 9.32 visits, and a High-Interest Cluster including 8 students with an average of 21.00 visits. The data analysis revealed significant disparities in visit interest across academic programs, where students from the Informatics Engineering program demonstrated higher levels of engagement compared to those from the Information Systems program, which was predominantly characterized by low visit frequency. These findings provide a scientific foundation for library management to formulate segmented service optimization policies, including retention programs for active users and personalized literacy stimulation strategies to enhance student engagement in academic programs with lower visit intensity

Abstract

Background: Duration of stay in the Intensive Care Unit (ICU) after lower gastrointestinal surgery is an important prognostic parameter that influences patient outcomes and the burden on hospital resources. Its determinants are multifactorial and complex, requiring identification through a systematic literature review. Objective: To identify and synthesize factors associated with the length of intensive care stay in patients after lower gastrointestinal surgery. Method: A systematic review using a narrative design was conducted. A literature search was conducted in the Google Scholar, Semantic Scholar, and PubMed NCBI databases (2015-2024). Articles were selected based on inclusion-exclusion criteria, assessed for quality, and data were extracted for thematic analysis. Results: From the 20 selected articles, the determining factors were grouped into four domains: (1) Patient Factors (comorbidity, frailty, malnutrition, psychocognitive disorders); (2) Procedure Factors (emergency surgery, anastomotic complications, long anesthesia duration, open surgical techniques); (3) Complications (nosocomial infections, delirium, renal and multiorgan dysfunction); and (4) Management & System Factors (ERAS protocols, goal-directed fluid therapy, early enteral nutrition, high-volume institutional experience). Conclusion: The length of intensive care stay after lower gastrointestinal surgery is determined by the dynamic interaction of patient factors, procedures, complications, and quality of management. Effective strategies to shorten it require a holistic approach that includes preoperative optimization, complication prevention, implementation of evidence-based protocols, and multidisciplinary collaboration.

Abstract

Factory location selection represents a strategic decision that significantly impacts the long-term operational success of manufacturing companies. This research aims to optimize the factory location selection decision-making process by applying the Analytical Hierarchy Process method, considering three fundamental criteria: operational costs, logistics accessibility, and labor availability. A quantitative approach was employed involving five expert respondents consisting of industrial practitioners and academics to conduct pairwise comparison assessments of four alternative industrial estate locations in West Java. The analysis results indicate that operational costs have the highest priority weight of 0.540, followed by logistics accessibility with a weight of 0.297, and labor availability with a weight of 0.163. Cikampek Industrial Estate emerged as the optimal location with a global priority weight of 0.300, excelling in operational cost efficiency despite having limitations in logistics accessibility. Consistency testing shows Consistency Ratio values ranging from 0.035 to 0.046, confirming the validity of respondent assessments. This research provides practical contributions in the form of a structured decision model that can assist manufacturing company management in making strategic production facility location decisions more objectively and measurably.

Abstract

Land degradation poses a significant threat to environmental sustainability and agricultural productivity, particularly in regions experiencing rapid land-use change and increasing anthropogenic pressure. Mapping land vulnerability to degradation is essential for supporting effective land management and spatial planning policies. This study aims to assess and map land vulnerability to degradation using a Geographic Information System (GIS) approach. The analysis integrates multiple biophysical and environmental factors, including slope, soil type, land use/land cover, rainfall intensity, and vegetation index. A weighted overlay method was applied, with factor weights determined using expert judgment and relevant literature to generate a land degradation vulnerability index. The results classify the study area into low, moderate, and high vulnerability zones. Areas with steep slopes, sparse vegetation cover, and intensive land use exhibit the highest vulnerability to degradation. The vulnerability map highlights spatial patterns that can support targeted land management interventions and conservation planning. This study demonstrates that GIS-based spatial analysis provides an effective and reliable framework for identifying land degradation risks and offers valuable insights for policymakers in promoting sustainable land management and mitigating land degradation impacts.

Abstract

This study implements Passivity-Based Control (PBC) on the Teensy 4.1 embedded platform for Flywheel Energy Storage System (FESS) equipped with wireless power flow monitoring. The objective of the study is to overcome the limitations of conventional controllers in handling nonlinear dynamics of FESS and integrate remote monitoring capabilities to support smart grid infrastructure. The research method uses an experimental approach by designing an Interconnection and Damping Assignment PBC (IDA-PBC) controller optimized for embedded computing limitations, implemented on Teensy 4.1 with a 10 kHz control loop. The system is integrated with an ESP32 wireless module for real-time data transmission to a remote dashboard. The results show that IDA-PBC is superior to Field-Oriented Control with an increase in rise time of 24.5%, settling time of 34.0%, overshoot of 74.4%, and disturbance rejection of 46.2%. Energy efficiency increases by 3.8% absolute (89.9% vs 86.1%) with lower total harmonic distortion. The implementation on Teensy 4.1 proved viable with 45.2% CPU utilization, while wireless monitoring achieved 18.5 ms latency and 0.12% packet loss. The contributions of this research include empirical validation of IDA-PBC on a real-world implementation, benchmarking of embedded platforms for nonlinear control, and demonstration of cyber-physical integration on FESS that supports the development of a more efficient and reliable smart grid.

Abstract

The rapid development of information system technology has influenced the business world, including trade, so that the dropshipping system has become popular; however, William Bookstore still conducts direct transactions on site without stock recording, so customers have to come to the store and book availability information is inaccurate. To overcome this problem, this study designed a web-based Book Dropshipping Information System using the Waterfall method—including needs analysis, ERD and UML design, implementation with PHP and MySQL, and testing—so that customers can search and buy books without coming directly, and the store can monitor stock easily. As a result, the system built is able to facilitate purchase transactions, record stock, and purchase history automatically, provide real-time monitoring, increase order transparency, and become an effective solution in supporting shopping convenience and store record management.
