A Practical Approach To The Optimization Of Vertical Linear Antenna Arrays For Dtv Reception
type: item
description: This study presents a practical optimization approach for a vertical linear Yagi-Uda array to enhance digital television (DTV) reception in rural and suburban areas. A manual parametric sweep in CST Studio Suite was used to optimize element lengths and spacing, targeting the DVB-T2 sub-band of 520–647 MHz. The proposed two-element vertical linear Yagi-Uda array achieved a return loss of −32.5 dB and an average gain improvement of 3.12 dB over a single-element configuration, with a peak gain of 12.9 dBi. Statistical analysis confirmed the improvement was significant (p < 0.05) without introducing adverse effects on bandwidth or impedance matching. Compared with published manual sweep and simulation-based optimization methods, this design achieves competitive performance while requiring no external optimization integration, offering a faster, more straightforward workflow for practical DTV deployment.

A Mobile Serious Game for Nutrition Education in Oman: LaObeseAn AHP-Guided Approach to Childhood Obesity Through Interactive Health and Learning Technologies
type: item
description: LaObese is an interdisciplinary serious game designed to address preschool obesity among Omani children by providing engaging gameplay and culturally relevant nutrition education. The title of the game derives from the Arabic words “La” meaning “no”, and “obesity”, signifying a stance against obesity. Healthy and familiar foods for children were prioritised through the Analytic Hierarchy Process (AHP) in collaboration with Omani nutrition specialists. Omani cuisine and culture serve as a basis for the simulation of healthy meal assembly, physical activity, knowledge assessments, and virtual doctor feedback across four interactive levels. Concise instructions and more motivating rewards improved usability and appeal during a pre-launch pilot test involving 6 six-year-olds and parents. The final evaluation utilised Usefulness, Satisfaction, and Ease of Use (USE) and User Motivation Inventory (UMI) questionnaires to assess children's diet, knowledge, usability, and motivation prior to and following the LaObese game. Participation in LaObese showed a statistically significant improvement in children’s healthy food choices (p < 0.001) and enhanced nutrition knowledge, as evidenced by quiz scores. The USE questionnaire indicated significant utility, ease of use, and enjoyment, while the UMI demonstrated a strong inner urge to play. Interviews with nutritionists affirmed the cultural significance and educational value of the game. As the first Arabic game to incorporate AHP-driven modelling for childhood obesity prevention, this work demonstrates how culturally sensitive, gamified interventions can promote healthier lifestyle behaviours among young children. The findings contribute to research in e-health, educational game design, and culturally informed human-computer interaction.

Performance Design and Evaluation of 4G LTE and 5G NSA Networks for LTE Home
type: item
description: The rapid evolution of cellular telecommunications has enabled high-speed network services, yet coverage in densely populated and geographically challenging areas remains a significant hurdle. This study proposes the implementation of 'LTE Home' using Software-Defined Radio (SDR) to mitigate issues such as weak signals, high interference, and limited sectoral antenna coverage. Performance was evaluated through drive tests in the Siteba area, comparing 4G LTE and 5G Non-standalone (NSA) networks across Radio Frequency (RF) parameters—including RSRP, RSRQ, SINR, and throughput—and Quality of Service (QoS) metrics. Initial measures indicated that while the 4G LTE network maintained relatively stable performance, with 38.81% of RSRP readings classified as 'good', the 5G NSA network underperformed. Specifically, 84.06% of 5G SINR readings were in the 'fair' category, and 68.58% of throughput readings were classified as 'poor'. The implementation of LTE Home technology yielded a substantial enhancement in network quality, particularly at measurement points initially exhibiting weak signals. On the 4G LTE network, RSRP improved from -88.9 dBm to -60 dBm, while RSRQ rose from -14.9 dB to -8 dB. Furthermore, the solution significantly optimised QoS, reducing latency to 16 milliseconds and jitter to 30 milliseconds. These findings demonstrate that SDR-based LTE Home implementation effectively addresses coverage gaps and enhances the consumer network experience in challenging environments.

Performance Analysis of an Off-Grid Solar Power Plant for Meeting Multi-Building Electricity Demands at Polytechnic State of Padang
type: item
description: This study evaluates the operational performance and economic potential of an off-grid solar power plant (SPP) installed at the Polytechnic State of Padang’s AC lecture building. Analysing data from January to May 2025, the research identifies a significant energy surplus, with the system generating between 10.36 kW and 36.84 kW against a maximum weekday demand of 15.54 kW. Technical analysis reveals that peak power reached a maximum of 40,298 W in April, reflecting optimal solar irradiation, while peak production consistently occurred between 09:00 and 10:00. The integrated battery system demonstrated robust performance, with the monthly average State of Charge (SoC) increasing from 57.12% in January to 63.23% in May, indicating progressive energy management optimisation. Charging and discharging efficiencies remained high, peaking at 93.19% in April. Despite a production decline in March due to inconsistent sky conditions, the system maintained a high total energy yield, with February recording the highest output at 2,960.07 kWh. Economic analysis indicates that the surplus energy presents a substantial opportunity for cost reduction. By redistributing excess power to adjacent buildings, the total potential cost savings for the five-month period were calculated at IDR 19,298,045.18. These findings suggest that the current off-grid installation is significantly underutilised and could serve as a primary energy source for a micro-grid network within the campus, enhancing both technical efficiency and financial sustainability.

Bending Strength Analysis of Polymer Composite Reinforced With Dried Leaves Filler
type: item
description: This study investigates the bending strength of polymer composite materials reinforced with crushed dried leaves as a natural filler, offering a sustainable alternative to synthetic fibres. Eight different composite specimens were fabricated using various combinations of cement, polyester resin, river sand, and dried leaves, with compositions guided by previous research. Specimens were tested according to ASTM C580 using a three-point bending setup to evaluate flexural properties. Results revealed that polyester resin-based composites (ROO and RSO) exhibited the highest flexural strength, with ROO reaching 26.84 MPa and demonstrating significant ductility, while RSO showed superior stiffness (modulus of elasticity: 2367.2 MPa). Composites containing dried leaves (especially RDS) showed moderate strength (14.05MPa) but improved strain (0.0724) characteristics, indicating potential for energy-absorbing applications. Failure modes ranged from brittle fractures to ductile deformations, revealing how different material compositions influence mechanical behaviour. The findings affirm the feasibility of incorporating minimally processed dried leaves in polymer composites for structural and semi-structural applications, promoting environmentally friendly material innovation.

Student Perception on Project-Based Learning in E-Sports Using CDIO Framework
type: item
description: This study investigates student perceptions of project-based learning (PBL) in an e-sports co-curricular course delivered using the Conceive–Design–Implement–Operate (CDIO) framework at three Malaysian polytechnics. A total of 44 students participated in the pilot study during the 2024/2025 academic session. Data were collected through a structured questionnaire adapted from Li Chen et al. (2022), which was validated for reliability (Cronbach’s alpha values ranged from 0.778 to 0.906 across different phases). Descriptive analysis was conducted using SPSS to examine students’ experiences in each CDIO phase, as well as their collaboration and communication skills. Findings indicate that students generally had a clear understanding of project objectives, applied creativity in design, engaged actively in implementation, and perceived their projects as successful and improvable. The findings indicate that CDIO-based PBL has the potential to enhance both technical and soft skills in e-sports education but with limited sample size and dependence on self-reported data, restrict the extent of results to be generalized. The study highlights the potential of CDIO to guide the development of structured e-sports curricula in three institution at Politeknik Malaysian while calling for further large-scale and inferential research.

The primary objective is to evaluate and compare the systems based on critical dimensions, interface architectures and design, recognition performance, database efficiency, and overall system reliability, to select the most suitable interface for creating a visitor face recognition system. Both systems were designed to automate the visitor check-in process, eliminate manual logging, and provide administrators with real-time data visualization. VFRA-DT features a dashboard-centric design tailored for administrative control, while VFRA-BI focuses on modularity and responsive design using the Bootstrap framework. The systems were deployed and tested under diverse environmental conditions—such as varying lighting, backgrounds, and distances—to evaluate their accuracy, response time, error rates, and usability. The results indicate that VFRA-BI achieves higher recognition accuracy (92% vs. 89%), faster attendance logging (1.8s vs. 2.1s), more responsive database querying, and reduced system downtime compared to the baseline. VFRA-BI’s use of a machine learning-driven approach and flexible interface enhances its adaptability in dynamic settings. Meanwhile, VFRA-DT remains effective in more controlled environments, offering a user-friendly interface with reliable recognition capabilities. Nonetheless, both systems face limitations in low-light and complex background scenarios, particularly with darker face images. This study provides comparative insights to support the development and implementation of efficient, secure, and scalable face recognition s…

An ErgoStroke Home Healthcare Management System with Gesture-Based Communication and Vital Sign Tracking for Stroke Patients
type: item
description: Providing optimal care for homebound stroke patients remains a significant challenge due to limited mobility and substantial communication barriers. This project presents the enhanced ErgoStroke system, an ergonomic, wearable healthcare solution designed to facilitate patient-caregiver communication and real-time health monitoring. The system utilises customised finger gloves integrated with biomedical sensors to track vital signs, including oxygen saturation, heart rate, and body temperature. A primary innovation of this redesign is the implementation of a dual-mode feedback mechanism: a speaker module provides auditory confirmation of recognised gestures, while an LCD screen ensures visual request identification in quiet environments. Data management is facilitated through an ESP32-based web dashboard developed with Bootstrap, enabling caregivers to visualise real-time data and review historical health trends. Usability testing conducted with a stroke patient demonstrated high system accuracy, ease of use, and a marked improvement in caregiver response times. However, technical evaluations identified hardware instabilities related to portable jumper cables and ESP32 port conflicts. To ensure consistent performance and commercial viability, the study recommends the development of a dedicated Printed Circuit Board (PCB). Ultimately, ErgoStroke offers a comprehensive and reliable solution that empowers patients, reduces caregiver burden, and enhances the quality of long-term home-based healthcare.

Critical Design Thinking As A Supervisory Framework For Final Year Project Development In Biometric System
type: item
description: This paper examines the application of the Critical Design Thinking (CDT) framework as a supervisory model for the development of Final Year Projects (FYPs) in technical higher education. Traditional supervision methods, which often emphasize system deliverables and code functionality, tend to overlook the cultivation of reflective thinking and adaptive problem-solving skills crucial for 21st-century engineering graduates. Addressing this issue, the study aims to demonstrate how CDT can foster deeper learning outcomes, enhance student engagement, and promote innovation through structured, reflective, and iterative processes. This study employed a qualitative case study approach at a Malaysian polytechnic, focusing on the supervision of a student developing a facial recognition-based attendance system. The project progressed through the five phases of CDT —empathizing, defining, ideating, prototyping, and testing—under close guidance from the supervisor, who served as a facilitator and co-learner. Data was collected through supervision logs, design journals, performance metrics, and reflective memos. Findings reveal that the system achieved up to 93% accuracy under optimal lighting and proximity conditions. Beyond technical success, the CDT approach contributed to notable gains in student coding proficiency, analytical reasoning, and contextual awareness. The iterative and collaborative nature of the CDT process facilitated timely adjustments to address environmental challenges, such as lighting variability and user interface considerations. The novelty of this study lies in repositioning FYP supervision as a dynamic, co-constructive practice rather than a linear delivery of technical tasks. This provides empirical validation of CDT as a scalable, pedagogically sound framework capable of aligning technical education with both industry expectations and broader societal needs. These insights offer significant implications for curriculum designers, academic supervisors,…

Enhancing Business Pitching Skills through Teaching Innovation: Leveraging Microsoft Team Speaker Coach
type: item
description: In today’s fast-evolving agribusiness landscape, the ability to deliver a persuasive business pitch is no longer optional; it is essential. Agropreneurs must be able to communicate innovative solutions clearly and confidently, particularly when seeking funding or entering competitive markets. Yet, agricultural education often lacks sufficient tools for real-time feedback and iterative improvement. To address this pedagogical gap, this study employed a within-subjects pre-post experimental design to evaluate the effect of Microsoft Teams Speaker Coach, an AI-powered communication feedback tool, on students’ pitching performance. A total of 33 Diploma in Agropreneurship students from the Faculty of Plantation and Agrotechnology, UiTM Sabah Branch, participated in this study. Descriptive analysis showed a significant improvement in performance; the mean pitching score improved from 27.97 (pre-test) to 30.76 (post-test) with a statistically significant difference confirmed by a paired samples t-test (t = 6.11, p = < .001.), indicating that the integration of AI-powered feedback produced a meaningful enhancement in students’ ability to pitch agricultural business ideas effectively. Beyond offering empirical evidence for AI’s role in education, this study aligns with Sustainable Development Goal 4 (Quality Education) by embedding innovation, digital literacy, and learner-centered strategies into skill-based curriculum design. Nonetheless, the study recognises a key limitation: research on AI coaching tools for pitching remains scarce, with limited scientific validation and evidence to confirm their sustained impact. This highlights the urgent need for future studies to expand the empirical base and rigorously test AI-assisted pedagogies to ensure that their adoption in education is both evidence-based and transformative.

Technology Acceptance and Its Impact on Student Dependency in Assignment Completion at Politeknik Kota Bharu
type: item
description: This study aims to assess the impact of perceived ease of use, perceived usefulness, and use of artificial intelligence (AI) tools on students’ reliance in completing academic assignments among diploma students at Malaysian Polytechnics. Based on the Technology Acceptance Model (TAM) by Davis (1989), this study examines the extent to which students accept and use AI tools such as ChatGPT, Grammarly, and QuillBot in the context of daily learning. This study uses a quantitative approach with an online questionnaire distributed to polytechnic students, and the data is analyzed using descriptive statistics and regression analysis to identify the relationship between variables. The findings show that perceptions of ease of use and usefulness of AI have a significant relationship with the level of students’ use and reliance. Over-reliance is detected when students use AI not only as a learning aid, but also as a shortcut in completing assignments, thus affecting critical thinking and academic autonomy. This study concludes that although AI benefits students in terms of understanding and productivity, the level of reliance needs to be monitored ethically and systematically. Therefore, the study recommends that higher education institutions develop clear AI usage policies, increase ethical awareness among students, and include AI literacy in the curriculum as an effort to balance effective technology use and self-directed learning.

type: item
description: Sugar cane bagasse, a discarded plant fibre remaining subsequent to the extraction of sugar cane juice, holds significant value as an abundant source of insoluble dietary fibres. These fibres offer a wide range of applications in various industries, including both the food and non-food sectors. Despite its potential, the comprehensive analysis of the physicochemical properties of sugar cane bagasse fibre for its role in cookie production is currently lacking or disregarded in evaluation processes. This study focused on utilizing sugar cane bagasse, a by-product of sugar extraction, for enhancing cookies. The bagasse was processed into powder after steam treatment, and cookies were made with different levels of bagasse powder (2%, 4%, and 6%). The study assessed the cookies' moisture content, crude fibre, and textural properties. The findings revealed that the cookies with bagasse (F1 6%) had higher moisture content (3.67±0.1274%), and the crude fibre content (2.02±0.871%) increased with the bagasse level. While there were no significant differences in hardness, cohesiveness, and springiness between the samples, cookies with bagasse had lower hardness (14047.33±21048.66) and springiness (0.366±0.152) but higher cohesiveness (0.0733±0.01155) than control cookies. The study highlights the potential of using sugar cane bagasse fibre in cookies, contributing to waste reduction in the food industry.

Physicochemical Properties And Formulation Screening Of Rabbit Soy Patty Using Plackett-Burman Design Method
type: item
description: Rabbit meat is a highly nutritious and lean protein source, containing essential amino acids crucial for tissue development. Soy dreg, a high-protein agricultural by-product, can potentially enhance the nutritional profile of rabbit meat products. Despite these benefits, rabbit meat remains an unpopular choice among Malaysian consumers. This study aimed to screen the formulation of rabbit soy patty using the Plackett-Burman design (PBD), analyse protein content and texture, and determine the best formulation through response optimization techniques. Minitab software version 20.2 was used to create 12 formulations based on PBD, and the resulting patties were evaluated for physicochemical properties. Texture analysis revealed that shortening significantly affected hardness with p-value 0.046 leading to a softer texture. Protein content analysis showed that ice, isolated soy protein (ISP), soy dreg, and rabbit meat had the most significant effect with p-values of 0.004, 0.005, 0.016, and 0.023, respectively. PBD successfully identified four key parameters (ice, ISP, soy dreg, and rabbit meat) that significantly influence protein content and texture. This study demonstrates the feasibility and potential advantages of incorporating soy dreg into rabbit meat patties to increase protein content and improve texture. Future research should focus on optimizing soy dreg inclusion levels, exploring ingredient interactions, and investigating new processing methods to further enhance the nutritional profile and sensory attributes of rabbit soy patties. Effective dissemination and collaboration with industry partners are crucial to promote the adoption of this sustainable approach to food production and address global food security challenges.

Performance And Durability Enhanced Composite Nanomaterial Membrane For Fuel Cell Applications
type: item
description: The proton exchange membrane (PEM) based on polybenzimidazole (PBI) is developing into a promising alternative to Nafion for high-temperature proton exchange membrane fuel cells (HT-PEMFC). While Nafion membranes are effective at atmospheric pressure and low temperatures, their performance deteriorates significantly at temperatures above 80 °C, making them unsuitable for the operation of HT-PEMFCs. PBI membranes, on the other hand, have excellent thermal stability and durability, making them well-suited for high-temperature conditions. However, their relatively low proton conductivity (between 10-15 mS/cm) poses a challenge for efficient HT-PEMFC performance. This study aims to synthesise and investigate the effects of incorporating the ionic liquid 1-butyl-3-methylimidazolium chloride ([BMIM][Cl]) on the physicochemical properties, ionic characteristics, and overall performance of polybenzimidazole/graphene oxide (PBI-GO) composite membranes in HT PEMFCs. The PBI composite membranes were prepared with a fixed weight percentage of 2 wt% graphene oxide (GO) and different concentrations of [BMIM][Cl] (from 1 to 3 wt%) by the solution casting method. The results showed that the composite membrane with 2 wt% [BMIM][Cl] (PBI-GO-[BMIM][Cl] (2 wt%)) exhibited optimal ion morphology distribution and lower acid leaching (about 54% loss after 5 hours). In addition, the PBI-GO-[BMIM][Cl] (2 wt%) membrane showed a significantly improved maximum power density of 128.45 mW cm-² at 160 °C compared to the PBI-GO-[BMIM][Cl] (2 wt%) composite membrane, which showed a maximum power density of only 106.70 mW cm-² at 25 °C. The improved performance of the PBI-GO-[BMIM][Cl] (2 wt%) membrane indicates its potential as a cost-effective and highly efficient material for HT-PEMFC applications. The use of this membrane in fuel cell technology could lead to significant cost savings in maintenance and energy consumption, while contributing to a reduction in carbon monoxide and carbon dioxide em…

The Experimental Speed Control of DC Shunt Motor Using Field Control Method via MATLAB Simulink
type: item
description: DC Shunt motor speed control using a field control method is a method that researchers have studied. The study of the characteristics of the motor, primarily in controlling the motor speed, is performed by this research with a constant input voltage. The research was done to indicate that both techniques, which are laboratory experiments and the MATLAB/Simulink model, can be executed. The outcome is to produce the desired speed of the DC Shunt Motor model via MATLAB/Simulink, as well as the result from the laboratory experiment. The external resistor is used in this experiment as a rheostat, where the resistance is varied. Variation of external resistance appears to reflect on the control of the speed of the DC motor. Simulation and laboratory experiment results indicate that the speed using the simulation model via MATLAB/Simulink is quite similar to the speed using the laboratory experiment result, and based on that, it shows the DC Shunt motor speed can be controlled using a field control method.

Developing Carbon Monoxide Gas Detectors In Vehicle Cabins
type: item
description: A vehicle will produce carbon monoxide (CO) gas when an incomplete combustion occurs. CO is odourless and colourless. The MQ-9 sensor is installed on the vehicle to detect the presence of CO in the vehicle cabin. The detection of CO in the vehicle cabin involves the MQ-9 Sensor, Arduino Mega 2560, and Raspberry Pi. When the MQ-9 Sensor detects CO in the vehicle's cabin, it will send a voltage to the Arduino Mega 2560, and the Liquid Crystal Display (LCD) will display the existence of CO. It will also display the activity of the MQ-9 Sensor. This system will generate an alarm signal and activate the Power Window Motor to pull the vehicle window open 2 inches to increase the Oxygen content in the vehicle. The alarm will sound again when the MQ-9 sensor no longer detects the presence of CO in the vehicle cabin, and the Power Window Motor will raise the window again. At the same time, Raspberry Pi will send information about the presence of CO to the vehicle owner's mobile phone. Indirectly, this approach will help prevent deaths from CO poisoning in vehicles.
