Abstract

The process of borrowing and returning books in some school libraries is still carried out manually, resulting in slower service times and a higher risk of data recording errors. Therefore, a library information system is needed to improve transaction efficiency and data management accuracy. This study aims to develop a web-based library information system integrated with a webcam-based barcode scanning feature, eliminating the need for additional scanning devices. The research employs a Research and Development (R&D) approach using the Waterfall model, which includes the stages of requirements analysis, system design, implementation, and testing. System evaluation was conducted using Black Box Testing, transaction time efficiency analysis, data accuracy measurement, assessment of lighting intensity on webcam-based barcode scanning performance, and usability testing using the System Usability Scale (SUS). The results indicate that all system functions operate properly. The system reduces the average transaction time from 72.06 seconds to 24.48 seconds (66% efficiency improvement) and increases data recording accuracy from 60% to 100%. Webcam-based barcode scanning performs optimally under lighting conditions of ≥150 lux. The usability evaluation achieved a SUS score of 85.8 (excellent). However, system performance is still influenced by lighting conditions and camera quality. Future research may focus on enhancing the system by incorporating image processing techniques or alternative identification technologies to further improve scanning accuracy.

Abstract

The increasing demand for energy presents challenges in efficient energy management. This study aims to develop and implement an Internet of Things (IoT)-based energy monitoring system called SENSE Plug, integrated with a Fiber To The Home (FTTH) network at the Universitas Pendidikan Indonesia campus laboratory. The system is designed to monitor real-time electricity consumption, detect voltage anomalies, and manage the electrical usage of connected electronic devices. The research uses an experimental approach by designing and testing the system in the laboratory. Data was collected using the PZEM-004T sensor connected to the NodeMCU ESP8266 microcontroller, with the measurements displayed on an OLED screen and sent to the IoT Cloud for remote monitoring. The system was tested on various electronic devices to measure voltage, current, active power, and power factor. The results indicate that the SENSE Plug system achieved high accuracy, with an average error of 0.44% for voltage and 0.41% for current. The system can also detect voltage anomalies and automatically disconnect the power supply to prevent damage to devices. In conclusion, SENSE Plug contributes to improving energy efficiency and offers a solution applicable to smart labs and other building environments

Abstract

This study focuses on analyzing the performance and optimizing the response time in handling fiber cut disruptions using a proactive website monitoring system to improve network operational efficiency. Fiber optic networks are critical infrastructure in telecommunication services; however, frequent fiber cut incidents can disrupt connectivity and affect service quality. The research employs a quantitative approach with descriptive and comparative analysis to evaluate the effectiveness of proactive monitoring systems. Data from fiber cut incidents in Kalimantan, covering periods before (September–October) and after (November–December) proactive monitoring implementation, were analyzed. Results indicate a significant improvement in operational efficiency, achieving 72.77% efficiency, primarily due to a reduction in response time by 70.83%. However, the resolution time increased by 33.70%, attributed to factors such as team adaptation, complexity of incidents, and external conditions like weather. The Root Cause Analysis (RCA) identified primary disruption causes: multiple cuts, animal interference, government activity, and vandalism. The proactive monitoring system significantly enhanced the detection and response to incidents, demonstrating its potential as a critical tool in network management.

Abstract

Employee attendance is one of the most crucial factors for an institution. There are various ways to address issues within an employee attendance system, and one of them is leveraging geolocation technology. Several studies investigate the controversies surrounding potential fraud and employee privacy threats when using geolocation access for attendance recording. Therefore, the system built in this research will prioritize utilizing geolocation access where location data during check-ins won’t be stored in the system, ensuring employee privacy remains intact. Moreover, this system will be designed to prevent employee fraud in manipulating locations. In its design, the system is constructed using the NEXT.JS framework and MySql as its database. Additionally, the research sample is drawn from two companies using an accidental sampling method as a data source. The result of this research is an attendance information system with web-based geolocation access that supports the attendance monitoring process within an institution. The development model used in this research is the RAD model, followed by using UML to document the system. Based on the final results obtained, a conclusion is drawn that this attendance system operates effectively, as evidenced by the conducted tests.

Abstract

The management of Standard Operating Procedures (SOPs), which were previously in the form of physical and manual documents and scattered across several storage media, caused several operational problems. These problems included difficulty in searching for documents, inconsistencies between the latest versions, delayed notifications, and a high risk of data loss, especially in the logistics industry. In this study, a web-based SOP management system was designed using Laravel and MySQL with the R&D+Waterfall method. Needs analysis was conducted through observation and interviews with five Manager ial respondents. The system is equipped with an approval workflow (waiting-approved-rejected) and RBAC 3-role (superadmin - department admin - viewer). Black Box Testing (12/12 scenarios passed) by Manager ial respondents showed that the system was able to significantly speed up the document search process and centralize the management of all SOPs into a single integrated platform.

Abstract

Diabetes mellitus is a chronic disease characterized by elevated blood glucose levels. Approximately 463 million adults worldwide have diabetes, and nearly half of them remain undiagnosed. Early diagnosis and treatment of diabetes are crucial to prevent serious complications. Continuous glucose monitoring (CGM) offers numerous advantages over traditional fingertip blood glucose measurements. CGM allows patients to track their glucose levels in real time, identify patterns, and adjust their diet and medication appropriately. This research presents a novel optical fiber-based glucose sensor utilizing the macrobending modulation technique. This method offers several advantages, including ease of use, low cost, and strong signal generation. The sensor exploits the refractive index difference between the glucose solution and the optical fiber. Variations in glucose concentration induce changes in the refractive index, which are converted into voltage signals. The sensor exhibits a sensitivity of 337 mV/decade and demonstrates a linear relationship between the voltage signal and glucose concentration within the range of 0-10 mM. The macro bending-modulated optical fiber sensor shows potential as a simple, cost-effective, and efficient CGM tool. Further research is necessary to enhance the sensor's sensitivity and stability and to evaluate its performance in biological samples.
