Abstract
This study explores the development of Kodular-based learning media to enhance the quality of informatics education. The study addresses the need of more engaging learning media and better technology integration in teaching using a Research and Development (R&D) design and a modified 3D model out of the 4D development model, including defining, designing, and developing. The research involved 20 students from SMK Negeri 1 Bangkinang, employing all stages of the development model: need analysis, media development, validation, and trial to students. The defining stage revealed inappropriate teaching method uses, leading students to have less motivation in learning. Consequently, this research developed learning media, focusing on number systems material (decimal, binary, octal, hexadecimal), organized in a visually appealing and concise format. In the designing phase, the Kodular media was developed to be user-friendly, featuring quizzes, exercises, and interactive modules. Validation results showed high feasibility scores, with media experts rate on 88.57% and material experts rate on 95%. During the developing stage, a trial to students yielded a score of 4.81 out of 5, classifying the media as "Very Good". Students praised its clarity, ease of use, and ability to make learning enjoyable. This study highlights the potential of Kodular-based media to increase engagement and support student-centred learning in vocational education.

Abstract
To improve the performance of wireless communications in indoor environment, it is important to optimize the signal quality by reducing the error rate between the received signal strength based on experimental data and estimating data. Due to the complexity of modern building layouts and construction materials, estimating received signal strength values based on these structural elements is challenging. The aim of this paper is to analyze received signal strength of the specific area by using the path loss exponent model of ray tracing techniques. In indoor environments, modeling radio wave propagation involves estimating the received signal strength at various points based on the layout and geometry of the space. This study involved three placement of 1.8 GHz AAU5940 Wall Mounted transmitters at height with 11.12 m and at different distances with 44.81 m, 95.4 m, and 108.2 m of specific receiver building. The Received Signal Strength Indicator (RSSI) readings are typically recorded to analyze and understand the ray tracing technique characteristics in a wireless communication environment. This paper presents analytical result of some practical experiments that helps to build an optimized signal quality for indoor environment using mathematical modelling with the help of MATLAB software.
摘要
为了提升室内环境中无线通信系统的性能，必须通过降低基于实验数据获得的接收信号强度与估计数据之间的误差率来优化信号质量。由于现代建筑结构布局复杂且建筑材料多样，仅依据建筑结构因素对接收信号强度进行估算具有较大的挑战性。本文旨在利用基于射线追踪（Ray Tracing）技术的路径损耗指数模型（Path Loss Exponent Model），分析特定区域内的接收信号强度。在室内环境中，无线电波传播建模需要依据空间布局和几何结构，对不同位置的接收信号强度进行估算。本研究在特定接收建筑物中布设了三台 1.8 GHz AAU5940 壁挂式发射机，安装高度均为 11.12 m，发射机与接收建筑之间的距离分别为 44.81 m、95.4 m 和 108.2 m。通过记录接收信号强度指示值（Received Signal Strength Indicator，RSSI），分析并研究无线通信环境中射线追踪技术的传播特性。本文结合 MATLAB 软件建立数学模型，对多项实际实验结果进行了分析，为优化室内无线通信环境中的信号质量提供了理论依据和技术支持。

Abstract
This study aims to develop a web-based registration system for prospective parking attendants at the UPTD Parking Service in the Transportation Department of Batam City. Currently, the process of managing prospective parking attendant data is done manually, leading to time-consuming registration procedures. The absence of a proper information system makes it difficult for prospective parking attendants to find information about the registration process at the Batam City Transportation Department. This system was developed by using PHP programming and MySQL database. The development follows the SDLC Waterfall model, which consists of five phases: requirements analysis, system design, coding, program testing, and system implementation. The system was modelled by using Unified Modeling Language (UML), including use case diagrams, activity diagrams, class diagrams, and sequence diagrams. System testing was conducted by using black-box testing and tested by users. The results of this study include the requirements analysis, system design with UML modeling, and eight supporting tables for the development of the web-based application. The system has been tested on local host and through black-box testing, and it is deemed successful in assisting the management of prospective parking attendant registration. However, the application is limited to the admin and user pages. There is a need for data classification on the system dashboard to present a more executive-level display in line with the registration form for prospective parking attendants. Additionally, there is a need for improvements in human resources to ensure proper operation and maintenance of the system.

Abstract
This study aimed to develop and evaluate Augmented Reality (AR)-based learning media for the Earth and Solar System topics in middle school science education. Using the Research and Development (R&D) approach with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation), the study developed AR media designed to enhance student understanding of complex scientific concepts. The effectiveness of the AR media was assessed through Aiken's V validation, practicality tests from teachers and students, and pre-test and post-test evaluations. The results showed that the AR media significantly improved student engagement, understanding, and academic performance. Aiken's V validation scores for usability, information, and interaction quality were above 0.8, indicating that the media was valid and effective. The practicality test revealed that teachers rated the media highly (93% usability), while students gave slightly lower ratings (81% usability). The N-gain score from pre-test and post-test evaluations showed a 56.2% improvement in students' knowledge, confirming the positive impact of the AR media on learning outcomes. Despite the challenges with usability for some students, the overall feedback supports AR's potential in enhancing science education, especially in rural settings. The study recommends further research to overcome usability challenges and optimize AR's classroom integration.

Abstract
Education is one of the main pillars in developing quality human resources. To ensure equal access to education, the government has launched various scholarship programs. However, the management and distribution of scholarships often face challenges in terms of accurate data collection and spatial distribution analysis. This study aims to map the distribution of scholarship recipients in Jambi Province using a Geographic Information System (GIS) approach with QGIS software. The research uses spatial data in the form of administrative boundaries of Jambi Province and non-spatial data on the number of scholarship recipients per district/city obtained from the JDAC Jambi official website. The data were processed using attribute joining, classification with the Natural Breaks (Jenks) method, and visualization through a choropleth map. The results show that scholarship recipients are unevenly distributed, with higher concentrations in urban and densely populated areas such as Jambi City and Muaro Jambi Regency, while regions like Tebo and Sarolangun have relatively low numbers. This indicates the influence of population density, availability of higher education institutions, and information accessibility on scholarship distribution. The use of QGIS proved effective in presenting spatial data visually and supporting data-driven policymaking. The study recommends that local governments utilize spatial analysis in scholarship distribution planning to enhance equity and program effectiveness.
摘要
教育是培养高素质人力资源的重要支柱之一。为保障教育机会均等，政府实施了多项奖学金计划。然而，在奖学金管理与发放过程中，仍面临数据采集准确性不足以及空间分布分析困难等问题。本研究旨在利用地理信息系统（Geographic Information System，GIS）方法，并结合 QGIS 软件，对印度尼西亚占碑省（Jambi Province）奖学金获得者的空间分布进行制图分析。研究采用空间数据（包括占碑省行政区划边界）以及来自 JDAC Jambi 官方网站的各县（市）奖学金获得者数量等非空间数据。数据处理过程包括属性连接（Attribute Joining）、采用自然断点法（Natural Breaks (Jenks)）进行分类，以及利用分级设色地图（Choropleth Map）进行可视化展示。研究结果表明，占碑省奖学金获得者分布存在明显的不均衡现象，奖学金获得者主要集中于占碑市（Jambi City）和穆阿罗占碑县（Muaro Jambi Regency）等城市及人口密集地区，而 Tebo 县和 Sarolangun 县等地区的获奖人数相对较少。这说明人口密度、高等教育机构分布以及信息获取便利性对奖学金分配具有显著影响。研究进一步表明，QGIS 能够有效实现空间数据的可视化表达，并为基于数据的教育政策制定提供有力支持。研究建议地方政府在制定奖学金分配政策时充分利用空间分析方法，以提高奖学金分配的公平性和项目实施效果。

Abstract
To improve the performance of wireless communications in indoor environment, it is important to optimize the signal quality by reducing the error rate between the received signal strength based on experimental data and estimating data. Due to the complexity of modern building layouts and construction materials, estimating signal strength values based on these structural elements is challenging. The aim of this paper is to analyse received signal strength of the specific area by using the path loss exponent model of ray tracing techniques. In indoor environments, modelling radio wave propagation involves estimating the received signal strength at various points based on the layout and geometry of the space. This study involved three placements of 1.8 GHz AAU5940 Wall Mounted transmitters at height with 11.12 m and at different distances with 44.81 m, 95.4 m, and 108.2 m of specific receiver building. The Received Signal Strength Indicator (RSSI) readings are typically recorded to analyse and understand the ray tracing technique characteristics in a wireless communication environment. This paper presents analytical results of some practical experiments that help to build an optimized signal quality for indoor environment using mathematical modelling with the help of MATLAB software.
摘要
为了提高室内环境中无线通信系统的性能，需要通过降低基于实验测量数据与估算数据之间接收信号强度的误差来优化信号质量。由于现代建筑物布局复杂、建筑材料种类繁多，仅依据这些结构因素估算信号强度具有较大的挑战性。本文旨在利用基于射线追踪（Ray Tracing）技术的路径损耗指数模型（Path Loss Exponent Model），分析特定区域内的接收信号强度。在室内环境中，无线电波传播建模需要依据空间布局和几何结构，对不同位置的接收信号强度进行估算。本研究在特定接收建筑物中布设了三台 1.8 GHz AAU5940 壁挂式发射机，安装高度均为 11.12 m，发射机与接收建筑之间的距离分别为 44.81 m、95.4 m 和 108.2 m。通过记录接收信号强度指示值（Received Signal Strength Indicator，RSSI），分析并研究无线通信环境中射线追踪技术的传播特性。本文结合 MATLAB 软件建立数学模型，对多项实际实验结果进行了分析，为优化室内无线通信环境中的信号质量提供了理论依据和技术支持。

Abstract
The rise of digital communication platforms based on the internet has heightened the demand for service quality that aligns with user expectations. Discord, a Voice over Internet Protocol and Instant messaging application, is widely embraced by various communities; however, complaints regarding system stability, service responsiveness, and user support continue to arise. This study aims to evaluate user satisfaction with the Discord application using the Electronic Service Quality (E-SERVQUAL) method. Employing a descriptive quantitative approach, data was collected through an online questionnaire from 128 active Discord users in Indonesia, selected via purposive sampling. The research instrument was crafted based on the six dimensions of E-SERVQUAL: Efficiency, Reliability, Fulfillment, Privacy, Responsiveness, and Contact, comparing users’ expectations with their perceptions. The findings reveal that all dimensions of E-SERVQUAL exhibit negative gap values. The Total Electronic Service Quality score of -0.44 indicates that the overall service quality of Discord falls short of user expectations, with the Responsiveness dimension showing the most significant gap. The study concludes that enhancing service quality, particularly in Responsiveness and user support, is vital for improving user satisfaction.
摘要
随着基于互联网的数字通信平台迅速发展，用户对符合其期望的服务质量提出了更高要求。Discord 作为一款集互联网语音通信（Voice over Internet Protocol，VoIP）和即时消息（Instant Messaging）于一体的应用程序，已被众多用户群体广泛采用。然而，关于系统稳定性、服务响应速度以及用户支持等方面的投诉仍然较为普遍。本研究旨在采用电子服务质量（Electronic Service Quality，E-SERVQUAL）方法，对 Discord 应用程序的用户满意度进行评估。研究采用描述性定量研究方法，通过在线问卷收集了印度尼西亚 128 名活跃 Discord 用户的数据，并采用目的抽样（Purposive Sampling）进行样本选择。研究工具依据 E-SERVQUAL 的六个维度构建，包括效率（Efficiency）、可靠性（Reliability）、履约性（Fulfillment）、隐私（Privacy）、响应性（Responsiveness）和联系（Contact），通过比较用户期望与实际感知来评价服务质量。研究结果表明，E-SERVQUAL 六个维度均呈现负向差距（Gap）值。其中，总电子服务质量（Total Electronic Service Quality）得分为 -0.44，说明 Discord 整体服务质量尚未达到用户期望，而响应性（Responsiveness）维度的差距最为明显。研究认为，提高服务质量，尤其是提升响应速度和完善用户支持服务，对于增强用户满意度具有重要意义。

Abstract
This study examined the development and evaluation of KAVRA as a UX-based digital fashion learning platform that integrates creative self-expression and brand identity communication. The research addressed the limitations of existing fashion design tools, which often present high technical barriers and lack support for identity expression and communicative interaction. A design thinking methodology was employed, involving iterative stages of empathize, define, ideate, prototype, and test, with participants consisting of undergraduate fashion design students and industry practitioners. The findings showed that KAVRA achieved high usability performance across key dimensions, including navigation ease (88%), visual accessibility (85%), time efficiency (90%), information clarity (82%), intuitive design (82%), and overall user satisfaction (82%). These results indicated that the platform effectively supports digital fashion learning by reducing cognitive load and enabling efficient task completion. Beyond functional usability, the platform also facilitated user interaction and engagement through intuitive visual design and communicative interface structures. Importantly, the study demonstrated that UX functions as a strategic communication interface that enables users to express creative identity and construct personal brand meaning through digital fashion design activities. Features such as 3D visualization, design customization, and collaborative interaction support reflective design processes and social engagement. The study concludes that UX-based platforms can serve not only as instructional media but also as communicative environments that integrate learning, interaction, and identity construction. These findings provide theoretical and practical implications for the development of future digital learning systems in creative domains.

Abstract
Effective employment supervision is critical for ensuring compliance with labour regulations and protecting worker rights. However, traditional paper-based approaches face significant challenges in the context of Indonesia's decentralized governance and limited supervisory resources. This study investigates the implementation of the Employment Information System, an online employment information system developed by the Manpower and Transmigration Office of Jambi Province, to optimize employment supervision. Using a mixed-methods approach combining analysis of system documentation and interviews with key stakeholders, this research assesses the system's functional capabilities, user access levels, data management workflows, and alignment with information systems success models. The findings reveal that Employment Information System integrates essential features including company registration, P2K3 (Occupational Safety and Health Committee) data management, complaint handling, and report generation across three distinct user levels. However, challenges persist in achieving optimal utilization, including limited digital infrastructure, insufficient training, and varying user responsiveness. This study contributes to the literature on digital transformation in labour governance within developing country contexts and offers practical recommendations for enhancing system adoption through targeted capacity building, feature integration, and policy reinforcement.
摘要
有效的劳动监察对于确保遵守劳动法规和保障劳动者权益具有重要意义。然而，在印度尼西亚实行地方分权治理以及劳动监察资源有限的背景下，传统的纸质管理方式面临诸多挑战。本研究旨在探讨由占碑省人力与移民局（Manpower and Transmigration Office of Jambi Province）开发的就业信息系统（Employment Information System）在优化劳动监察中的应用效果。研究采用混合研究方法，通过系统文档分析与关键利益相关者访谈相结合，对系统的功能特性、用户权限层级、数据管理流程以及其与信息系统成功模型的一致性进行了综合评估。研究结果表明，就业信息系统集成了企业注册、P2K3（职业安全与健康委员会，Occupational Safety and Health Committee）数据管理、投诉处理以及报表生成等核心功能，并支持三个不同层级的用户权限管理。然而，系统在推广应用过程中仍面临数字基础设施不足、用户培训有限以及用户响应程度不一致等问题，影响了系统效能的充分发挥。本研究丰富了发展中国家劳动治理数字化转型领域的相关研究，并提出通过加强能力建设、完善系统功能集成以及强化政策支持等措施，以进一步提升就业信息系统的推广应用效果。

Abstract
Computer repair service businesses that still rely on manual, chronologically ordered queues commonly experience a structural inefficiency: short, simple jobs are delayed behind longer and more complex repairs, which inflates average customer waiting time and removes any real-time visibility into repair status. This problem mirrors a well-documented limitation of First Come First Served (FCFS) scheduling in computing systems, where job ordering by arrival time rather than job characteristics produces suboptimal queue performance. This study addressed that gap by designing and implementing a web-based Service and Repair Management Information System that embeds the Shortest Job First (SJF) algorithm, strengthened with an aging mechanism to prevent the starvation of long-duration jobs. The system was developed using the Waterfall model, built on the Laravel 10 framework with a MySQL database, and structured around four role-based modules: Admin, Technician, Director, and Customer. The scheduling logic applied the priority formula Priority = Duration − (Waiting Time × 0.5), which dynamically lowers a job's priority value the longer it waits, gradually moving long-duration jobs toward the front of the queue without abandoning the core SJF principle of minimizing average waiting time. Black Box Testing confirmed that all ten primary system functions, including the SJF queue calculation, the aging mechanism, real-time status updates, and the public tracking portal, operated correctly and met the defined functional requirements. The findings indicate that the integration of an algorithmic scheduling mechanism into a web-based service management platform is both technically feasible and operationally effective for small computer repair businesses, extending the application of SJF scheduling beyond its traditional CPU-scheduling domain into commercial service queue management.
摘要
仍然采用人工按先后顺序排队方式的计算机维修服务企业普遍面临一种结构性效率问题：耗时较短、操作简单的维修任务往往需要等待较长且复杂的维修任务完成后才能处理，从而增加了客户的平均等待时间，并且无法实现维修进度的实时可视化。这一问题与计算机系统中广为人知的先来先服务（First Come First Served，FCFS）调度算法存在相似局限性，即按照任务到达时间而非任务特性进行排序，导致队列调度效率较低。针对这一问题，本研究设计并开发了一套基于 Web 的服务与维修管理信息系统，在系统中集成最短作业优先（Shortest Job First，SJF）算法，并引入老化机制（Aging Mechanism），以避免执行时间较长任务出现“饥饿”（Starvation）现象。系统采用瀑布模型（Waterfall）进行开发，基于 Laravel 10 框架和 MySQL 数据库构建，并设计了管理员（Admin）、技术人员（Technician）、主管（Director）和客户（Customer）四类角色模块。系统调度逻辑采用优先级计算公式：Priority = Duration − (Waiting Time × 0.5)，即随着等待时间增加，任务优先级值逐渐降低，使耗时较长的任务能够逐步提前进入队列，而不会违背 SJF 最小化平均等待时间的核心原则。黑盒测试（Black Box Testing）结果表明，系统的十项核心功能均运行正常，包括 SJF 队列计算、老化机制、维修状态实时更新以及公众查询门户等功能，均满足既定功能需求。研究结果表明，将算法化调度机制集成到基于 Web 的服务管理平台不仅具有良好的技术可行性，而且能够有效提升小型计算机维修企业的运营效率，同时将 SJF 调度算法的应用从传统 CPU 调度领域扩展到商业服务队列管理领域。
