Abstract

This study investigates the implementation of a peer teaching model assisted by trainer media to support students' practical competency in engine management system learning in vocational education. The study employed a Classroom Action Research (CAR) design integrated with a mixed-methods approach. The research was conducted through two action cycles consisting of planning, action, observation, and reflection. Quantitative data were obtained from students' practical competency assessments and teacher performance observations, while qualitative data were collected through classroom observations, documentation, and reflection records. The quantitative data were analyzed descriptively by comparing competency achievement and teacher performance across the action cycles, while qualitative data were analyzed thematically with the assistance of NVivo. The results showed a substantial descriptive improvement in students' practical competency. The proportion of students achieving the Competent category increased from 51% in Cycle I to 86% in Cycle II, representing an increase of 35 percentage points and exceeding the predetermined success criterion of ?85%. Teacher performance also increased from 69 in Cycle I to 87 in Cycle II, representing an improvement of 18 points and exceeding the predetermined criterion of ?80%. The qualitative findings indicated that the learning process was characterized by increased peer interaction, practical engagement with trainer media, teacher facilitation, and reflective improvement across the action cycles. The findings suggest that the integration of peer teaching, trainer-supported practical learning, and reflective teacher facilitation provides a coherent pedagogical approach for competency-oriented vocational learning. However, because individual-level data were unavailable for inferential analysis and the study did not employ a comparison group, the findings should be interpreted as context-specific evidence of instructional improvement rather than definitive evidence of causal effectiveness

Abstract

Large retail, logistics, and financial enterprises operate geographically dispersed branch networks in which wide area network scalability, availability, and recovery performance directly affect business continuity. This study investigates the scalability limitations of software-defined wide area network architectures for enterprise networks with more than 20,000 branches. It develops a distributed, pod-based Aruba SD-WAN architecture designed for this operating scale. The proposed architecture partitions branches into routing pods of approximately 3,000 sites, with each pod anchored by redundant head-ends distributed across two geographically separated data centers configured in an active-passive arrangement. Each branch employs a dual-gateway edge with four prioritized IPSec tunnels to provide path redundancy and deterministic failover. Analytical models are formulated to relate branch population to pod count, head-end requirements, aggregate tunnel volume, and control-plane peering load. The architecture is evaluated for branch populations ranging from 3,000 to 30,000 sites using control-plane capacity, tunnel scalability, availability, and operational recovery as the principal evaluation measures. The results indicate that hierarchical pod partitioning maintains routing and peering loads within platform capacity limits while supporting progressive branch expansion. Operational measurements show that head-end failover is completed within one minute, while inter-data-center failover is completed within three minutes. The architecture also provides predictable control-plane behavior by limiting the routing domain and distributing tunnel and peering workloads across independent pods. This approach further reduces the concentration of routing dependencies and enables incremental capacity expansion without redesigning the entire enterprise network. These findings demonstrate that distributed pod-based partitioning can provide a scalable and resilient SD-WAN architecture for hyperscale enterprise branch networks, enabling controlled growth while maintaining operational continuity and predictable failover performance

Abstract

The ABC facility is a packaging area at PT XYZ that plans to construct a pipeline to transport wastewater to the wastewater treatment plant (WWTP). Several factors must be considered in the design, including flow characteristics, pipe diameter, pressure head, and pump selection. The proposed pipeline is designed for a flow rate of 0.0015 m³/s using a 1.5-inch diameter pipe, resulting in a flow velocity of 1.32 m/s. Computational Fluid Dynamics (CFD) was employed to analyze flow behavior within the pipeline by integrating theoretical principles and numerical simulation. The simulation was conducted using the student version of SolidWorks to identify flow phenomena and evaluate the hydraulic performance of the proposed system. The results indicate that the flow within the pipeline exhibits turbulent characteristics, with a turbulence intensity of 1.87%. This turbulence intensity confirms the presence of turbulence in the pipeline connecting the ABC facility and the WWTP, indicating transitional flow behavior under the simulated operating conditions. The analysis also determined a pressure head of 42.87 m. Based on the calculated hydraulic requirements, the pump power capacity required to transfer wastewater from the ABC facility to the WWTP is approximately 3.92 kW. Considering the simulated flow conditions, pressure head, required capacity, safety factors, and pump efficiency, the EBARA GSD2 32-200.1 centrifugal pump with a 202 mm impeller diameter was identified as a suitable option. The selected pump can accommodate flow rates ranging from 4 to 37 m³/h and pressure heads of up to 52 m, with compatible motor capacities ranging from 2.5 to 7.5 kW. These results provide a technical basis for pipeline and pump selection to support reliable wastewater transfer from the ABC facility to WWTP

Abstract

Growing demand for broadband-dependent services, including cloud computing, telemedicine, ultra-high-definition streaming, enterprise remote work, and Internet of Things connectivity, has increased pressure on cable operators to expand network capacity, reduce latency, and maintain scalable infrastructure. This study examines the architectural requirements, multi-vendor interoperability challenges, and phased deployment strategies associated with the evolution of Data Over Cable Service Interface Specification (DOCSIS) 4.0 over existing Hybrid Fiber-Coaxial infrastructure. The analysis focuses on Extended Spectrum DOCSIS and Full Duplex DOCSIS architectures and uses a leading U.S. Tier-1 cable operator as an operational reference for large-scale deployment considerations. Industry validation results, deployment practices, interoperability requirements, and the emerging 3 GHz DOCSIS roadmap are synthesized to establish a structured framework for national-scale implementation in heterogeneous multi-vendor environments. The findings indicate that interoperability among Cable Modem Termination Systems, Remote PHY Devices, and Customer Premises Equipment from multiple vendors can be supported through systematic interoperability testing, coordinated firmware lifecycle governance, and standardized Proactive Network Maintenance data management. The analysis also indicates that phased deployment can limit service disruption and operational risk while enabling progressive migration toward multi-gigabit broadband services. The proposed framework integrates network architecture planning, vendor interoperability management, operational readiness, and deployment sequencing into a coordinated implementation approach. This approach provides cable operators with a practical basis for managing technological transition from existing Hybrid Fiber-Coaxial networks toward higher-capacity DOCSIS 4.0 architectures while accommodating heterogeneous equipment, evolving spectrum requirements, and long-term network scalability. The framework also supports structured decision-making for aligning technical modernization with operational continuity during large-scale broadband network transformation

Abstract

The advancement of information and communication technology has profoundly altered numerous facets of society, particularly in education. Institutions of higher education have significantly profited from these improvements, especially in improving services and facilities for students, prospective students, and the public. The public requires broad understanding involving campus conditions and circumstances to enhance their advertising and recognition activities for broader acknowledgment.  Therefore, suitable digital media are required to deliver comprehensive and informative campus information. The utilization of virtual reality (VR) technology for virtual campus tours is an increasingly popular innovation, enabling visitors to explore the campus and feel its ambiance without physical presence. Nonetheless, numerous organizations have difficulties in developing genuinely interactive and immersive virtual tour experiences. This research is to investigate the application of A-Frame in developing a web-based campus tour to improve user engagement and immersion. The employed research methodology is research and development (RD) utilizing a Waterfall development model that are include: requirements analysis, system design, implementation and development, and evaluation and improvement. Sampling for functional testing is involved 100 secondary school’s students in Jawa Barat. The findings indicate that employing A-Frame for developing a campus online tour can yield a gratifying, interactive, and immersive experience. Furthermore, functional and security assessments demonstrate that the system operates effectively and is secure for use. System assessment and enhancements are conducted in response to user feedback to guarantee the system's relevance and alignment with user requirements. This research offers a viable method for enhancing the engagement and immersion of campus tours, serving as a reference for other educational institutions in the adoption of VR technology

Abstract

Large Language Models (LLMs) have emerged as promising tools for reducing the cognitive burden associated with interpreting operational data in modern distributed systems. However, their probabilistic behavior creates challenges when LLM-generated decisions are directly connected to operational tools, particularly in cloud-native environments characterized by microservices, continuous deployment, and rapidly increasing volumes of observability data. This article develops and examines a two-phase architecture that separates intelligent routing from deterministic execution. The routing phase uses multi-agent coordination to interpret incident context, identify relevant workflows, and select appropriate operational actions, while the execution phase invokes authorized tools through schema validation, constraint enforcement, and controlled interfaces. The architecture is designed to bound LLM decision-making without eliminating its ability to handle complex and variable incident scenarios. Evaluation of the proposed design across incident management, network infrastructure optimization, and cybersecurity automation indicates that the separation improves operational control by restricting probabilistic reasoning from directly exercising operational authority. The constraint-driven execution layer also supports reproducible tool invocation, offline evaluation, localized failure diagnosis, and auditable decision paths. Across the examined application domains, the architecture demonstrates how LLM-based reasoning can be integrated with deterministic operational mechanisms while preserving human oversight and system reliability. The findings indicate that separating probabilistic cognition from operational execution provides a practical architectural mechanism for reducing hallucination-related risks and improving the controllability of LLM-enabled automation. The proposed approach, therefore, establishes a foundation for operational intelligence systems that can move beyond reactive manual processes toward more autonomous and proactive incident management while maintaining traceability, constraint compliance, and human governance as operational complexity continues to increase

Abstract

This research aims to design, build, and test a 72 Volt 20 Ah lithium-ion battery pack for the Pesut EV.1 Mahakam Team electric go-kart. The battery pack is designed with a 20S4P configuration using lithium-ion cells, equipped with a Daly 72 Volt 100 Ampere Battery Management System (BMS), and modeled in CAD software. Testing was carried out through three charging and discharging trials to analyze the voltage, current, and temperature parameters during the process. To enable real-time monitoring, visualization, and data logging during go-kart operation, an IoT-based telemetry system was integrated using a microcontroller and dedicated sensors communicating via the MQTT protocol. In addition, thermal simulations were carried out using FEA software. The test results demonstrated stable and consistent battery performance. During the charging process, the voltage gradually increased from 68 V to 84 V with a stable charging current in the range of 5.90 A – 12.37 A, yielding an average absorbed capacity of 21.15 Ah and input energy of 1,612.11 Wh, while the temperature remained between 25.00 °C and 28.50 °C. Meanwhile, during the discharging process, the voltage gradually decreased from 84 V to approximately 68 V, with the discharge current reaching up to 68.7 A and a maximum temperature of 43 °C. However, dynamic discharge capacity calculation using a 30-second logging interval resulted in overestimation errors due to transient current fluctuations, indicating the need for higher sampling frequencies in future evaluations. Simulation results also demonstrated an even temperature distribution and no overheating during operation. The results indicate that the developed battery pack performed reliably under the tested charging and discharging conditions for Pesut EV.1 Electric Go-Kart usage and racing applications.

Abstract

The Trusmi small-scale batik industry is one of Indonesia’s prominent cultural heritage clusters, yet it faces challenges related to limited customer reach, intense competition from mass-produced batik, and inadequate financial management. This study aims to redesign its business model to strengthen competitiveness while preserving cultural authenticity. The Business Model Canvas (BMC) framework was employed to identify existing weaknesses and formulate strategic improvements. Data were collected through in-depth interviews with 15 batik artisans, direct observations of production and marketing activities, and benchmarking against successful batik enterprises. The analysis comprised three stages: problem identification, solution formulation, and BMC redesign. The findings identified critical weaknesses in customer segmentation, sales channels, customer relationships, resource management, and cost structure. To address these issues, the study proposes expanding customer segments through digital marketing, developing innovative and environmentally friendly designs, strengthening partnerships with government institutions and tourism stakeholders, implementing cooperative-based procurement systems, and improving financial management practices. The redesigned BMC integrates diversified revenue streams, hybrid production techniques, and customer loyalty programs to enhance business sustainability and market responsiveness. The proposed business model is expected to improve market penetration, operational efficiency, financial performance, and customer loyalty while maintaining the cultural and artistic heritage of Trusmi batik. This study contributes to the literature on creative industries and small and medium-sized enterprise development by presenting a practical, culturally grounded framework for business model innovation. The framework may also serve as a reference for other traditional craft industries seeking to balance cultural preservation, digital transformation, and sustainable economic growth in increasingly competitive markets

Abstract

Real-time enterprise platforms continuously deliver information to users and services, creating a need for access-control decisions that remain valid throughout event delivery rather than only at the time of an initial request. This article proposes a Zero Trust access architecture for real-time, event-driven enterprise platforms, in which subscription authorization is treated as a distinct access-control decision with a lifecycle that includes authorization, cached delivery, revalidation, and invalidation. The proposed architecture integrates identity and authorization services, API gateways, policy decision and enforcement points, role- and attribute-based access control, workload identity for background services, and centralized auditing. A defined threat model specifies the security conditions the architecture addresses, including unauthorized subscriptions, privilege changes during active delivery, stale authorization states, and misuse of service identities. The approach combines a layered reference architecture, a worked subscription lifecycle, explicit policy and enforcement logic, and a microbenchmark comparing per-event policy evaluation with precomputed entitlements on a single-host test environment. The benchmark indicates that moving routine authorization decisions outside the event-delivery path reduces per-event authorization cost by more than two orders of magnitude. However, the result is based on a single, unreplicated run per strategy and therefore provides an architectural indication rather than stable performance evidence or production-scale validation. Clinical monitoring is used as the primary application context, with financial risk processing, insurance claims routing, and specialty pharmacy fulfillment as supporting examples. The proposed architecture provides a structured basis for implementing continuous authorization in real-time enterprise platforms while preserving explicit security controls, supporting authorization-state changes throughout active subscriptions, and limiting authorization overhead within event-delivery paths

Abstract

The emergence of hybrid and multi-cloud computing has highlighted a persistent structural challenge in enterprise architecture: endpoint management and cloud operations remain largely separated, resulting in operational friction, security vulnerabilities, and inconsistencies in governance and control. This article examines hyper-converged cloud-endpoint integration as a potential architectural approach to addressing technological diversity and improving enterprise management across distributed digital environments. Hyper-convergence is conceptualized as an extension of hyper-converged infrastructure (HCI) principles beyond the data center, encompassing endpoint devices and cloud environments. The discussion adopts a conceptual and architectural approach to examine the convergence of technologies, security mechanisms, automation practices, and governance processes. Key enabling components include Unified Endpoint Management (UEM), Infrastructure as Code (IaC), Policy-as-Code, event-driven synchronization, Zero Trust Network Access (ZTNA), and artificial intelligence for predictive maintenance and self-healing endpoint operations. The analysis identifies the potential of these components to support centralized policy enforcement, consistent configuration management, automated remediation, and coordinated operational visibility across heterogeneous infrastructures. It also highlights the importance of phased implementation, interoperability, organizational readiness, and clearly defined governance responsibilities in translating architectural principles into operational practice. Security and compliance are treated as foundational requirements rather than optional additions, particularly in environments subject to evolving regulatory obligations and demands for distributed access. The article concludes that hyper-converged cloud-endpoint integration offers a promising architectural direction for enterprises seeking to strengthen operational resilience, improve security consistency, and enhance regulatory compliance. However, its effectiveness depends on appropriate security controls, interoperable technologies, continuous monitoring, and systematic implementation. The proposed approach, therefore, provides a conceptual foundation for further architectural development and empirical evaluation of integrated enterprise environments across diverse organizational and technological contexts.
