Abstract

The availability of interactive learning media determines the success of educational processes, especially in implementing the Merdeka Curriculum. This study was motivated by low learning interest (mean 53.9%) and IPAS learning outcomes (mean 68.5; below the KKTP of 75) among fourth-grade students at SD Negeri 1 Nglebo, Trenggalek, attributable to limited instructional media. This study developed the Android-based interactive learning application "KaLoT" (Keragaman Budaya memuat Kearifan Lokal Trenggalek), integrating national cultural diversity with Trenggalek local wisdom. The Research and Development (R&D) methodology with the ADDIE model was employed, involving 14 students (SD Negeri 2 Suruh) for small-group trials and 23 students (SD Negeri 1 Nglebo) for large-group trials. Data were collected via expert validation sheets, teacher response questionnaires, classroom observation sheets, learning interest questionnaires, and HOTS-based pre-test/post-test assessments, analyzed using quantitative descriptive analysis and N-Gain. Results demonstrated: (1) very high validity at 93.85%; (2) very high practicality averaging 93.46%; and (3) effective improvement of learning outcomes with N-Gain of 0.71 (small group), 0.75 (Class IVA), and 0.66 (Class IVB), with learning interest rising from 53.5–55.8% to 91.0–93.2%. The study concludes that "KaLoT" is valid, practical, and effective for IPAS learning in Grade IV elementary school.

Abstract

The rapid expansion of big data, Internet of Things (IoT) systems, and artificial intelligence (AI) has transformed the conditions under which privacy and personal data protection operate. In the algorithmic age, privacy is increasingly challenged not only as an individual right but also as a structural condition of socio-technical systems. This article examines whether privacy is merely adapting to technological change or undergoing a deeper paradigmatic transformation. Focusing on Türkiye’s Personal Data Protection Law (KVKK No. 6698) in comparison with the European Union’s General Data Protection Regulation (GDPR), the study investigates the changing legal and operational foundations of personal data protection, particularly the declining centrality of explicit consent and the growing role of broader governance mechanisms. Methodologically, the article adopts a qualitative multi-method design combining comparative legal analysis, doctrinal examination, and a socio-technical case study of six smart city applications in Türkiye. The findings reveal a gap between formal regulatory alignment and substantively effective protection, especially in smart city systems characterized by ambient data collection, system interoperability, and limited user contestability. The study concludes that privacy is being restructured from an individual consent-based model toward a more systemic governance condition. Accordingly, sustainable privacy protection requires integrated legal, technical, and societal governance mechanisms.

Abstract

This journal research was conducted with the primary objective of developing a system capable of visualizing the route and distance from SMK Raden Umar Said Kudus to various boarding houses located within Kudus Regency. The increasing number of students enrolling in the school, including those from outside the region, has created a growing need for accessible information regarding temporary accommodation near the school. Therefore, the proposed system is designed to assist students in identifying suitable boarding houses by providing geographic visualization of their locations and distances from the school. To achieve this objective, the system utilizes the Leaflet library as the main mapping tool to visualize geographic information in an interactive web based environment. Leaflet enables the display of maps, routes, and distance calculations in a user friendly format, making it easier for users to understand spatial relationships between the school and nearby boarding houses. The system itself is developed using PHP as the primary programming language. In addition, JavaScript is integrated with the Leaflet library to handle map interactions and geographic data visualization. The Waterfall development model was chosen as the system development methodology due to its clear and sequential. Through this approach, the research aims to produce a functional Geographic Information System that helps students efficiently locate temporary housing during their study period at SMK Raden Umar Said Kudus while also providing useful information for boarding house owners.

Abstract

This study aims to design and implement a Web-Based Warehouse Information System with Barcodes at CV. Bulu Utama Tobacco. The background of this study stems from the problems faced by the company, namely the manual recording of stock items. This method often causes problems such as the risk of recording errors (human error), delays in reporting, and difficulties in real-time tracking of goods. The literature review refers to previous studies on web-based inventory information systems, barcode systems, and warehouse management. The results of the study show that the implementation of a barcode-based system has been proven to improve accuracy, efficiency, and transparency in inventory management, although previous studies were limited to manual web-based recording without barcode integration. The research method used was a qualitative approach with a case study at CV. Bulu Utama Tobacco. Data collection techniques were carried out through observation, interviews, and documentation. The system was developed using the UML modeling method (Use Case, Activity Diagram, and Flowchart) and implemented with web technology (PHP/Python, MySQL, and Barcode Scanner). Testing was conducted using Black Box Testing to ensure the functionality of the system.The results showed that the system was able to automatically record incoming and outgoing goods through barcodes, generate real-time stock reports, and reduce manual recording errors. The discussion confirmed that this information system not only improved operational efficiency but also provided strategic benefits in supporting management decision-making.

Abstract

In today's age of technology, web applications have become essential parts of the environment. Due to easy accessibility of the internet, the user can engage in actions without considering the possible impact, leading individuals and organizations to commit such actions freely. As a result, there has been an upsurge in cyber-attacks against web applications that are prone to attacks. Mitigation is achieved using static code analysis with SonarQube in order to detect vulnerabilities within the web application code. In this case, the aim is to contribute to developers through the recommendation on how to develop their web applications while considering security aspects. SSDLC is utilized to manage the web application used during the simulation of the cyber-attacks and mitigation of the impacts thereof. Results are reported as comparisons made before and after mitigation. Before implementation of mitigation measures, the web application was vulnerable to all simulated cyber-attacks. After implementation of mitigation measures, it became clear from analyses that the attack had no way of exploiting the secured vulnerabilities.

Abstract

Radiotherapy queues are often managed by referral date and manual clinician judgment, although limited linear accelerator capacity requires prioritization that is clinically transparent, operationally auditable, and fair. This study evaluates RadOnco-Priority, a machine learning-enabled decision support framework for radiotherapy queue prioritization, using a de-identified real-world retrospective dataset of 240 radiotherapy referral records rather than simulated or synthetic patient records. The system combines a literature-informed rule-based urgency score with supervised machine learning models to identify patients requiring accelerated booking. Accelerated booking need was defined a priori as an operational triage label reflecting clinician-documented priority, urgent symptoms, time-sensitive tumor-site and treatment-intent combinations, accumulated referral delay, and planning complexity. Logistic regression, random forest, and gradient boosting were trained to predict accelerated booking need, while a capacity-aware scheduling simulation evaluated waiting-time redistribution. To address potential circularity, additional ablation analyses were performed with the aggregate urgency score removed from the predictors. In the held-out test set, logistic regression achieved the highest discrimination in the full-feature model (AUC 0.91), with sensitivity-oriented classification favoring reduced false negatives. Performance remained acceptable after removing the aggregate urgency score, indicating that the model did not rely solely on the pre-specified scoring logic. The scheduling simulation reduced median waiting time in the high-priority group and decreased the proportion of high-priority patients waiting more than 28 days. These findings support RadOnco-Priority as an interpretable, human-governed information-system framework for radiotherapy queue management. Prospective multicenter validation, fairness monitoring, and local ethics approval remain required before routine implementation.

Abstract

The Screening Assist Information System v3.1 is a web-based application designed to support the substance abuse screening process at the National Narcotics Agency (BNN) of Sidoarjo Regency. This system uses the ASSIST (Alcohol, Smoking and Substance Involvement Screening Test) method from the WHO as an early detection tool for substance use risks. The system was developed using a Research and Development (R&D) approach with the Waterfall model in the System Development Life Cycle (SDLC). This information system was created using the PHP programming language and Mysql database. With its time efficiency, scoring accuracy, and data security, this system is an effective digital solution in supporting efforts to prevent and combat drug abuse in the Sidoarjo Regency. The system evaluation was conducted using the Blackbox Testing method, which showed that all features functioned properly, and the User Acceptance Testing (UAT) method was used to measure user satisfaction with a result of 87.6% . This percentage reflects the expectation that students provided honest answers, so that the data obtained was close to the actual level of validity. Overall, the evaluation results indicate that the developed information system can serve as an effective, adaptive digital solution that supports professional and structured efforts to prevent and address drug abuse.
