    Journal of Advanced Research in Applied Mechanics, 2025
    This paper explores the opportunities of applying RFID (radio-frequency identification) technology in smart agriculture. With the projected increase in global population and the resulting higher demand for food production, the agricultural industry is under pressure to find more efficient and sustainable ways to meet these needs. Radio-frequency identification (RFID) technology has been recently adopted in the agriculture industry as a means of improving efficiency and productivity towards achieving smart agriculture. RFID technology is revolutionizing smart agriculture, offering automation, real-time monitoring and data-driven decision-making. Integrating RFID tags with plants and soil samples optimizes resource utilization, crop health management, traceability and quality assurance. RFID in smart agriculture offers opportunities for resource optimization, crop health management, traceability and automation. Leveraging RFID technology, farmers can elevate productivity, reduce costs, improve sustainability and meet global demands. Adopting RFID in agriculture revolutionizes traditional practices, enabling efficient and sustainable farming. RFID-enabled traceability enhances food safety, quality assurance and transparency in the food supply chain. The objective of this paper is to explore the potential of RFID technology in smart agriculture and highlight the significance of effective RFID antenna design for optimizing food production, addressing global challenges and fostering a more efficient, sustainable and resilient agricultural sector.

    The technique for creating Ground Stroke Density (GSD) maps utilizing data from Peninsular Malaysia in 2023 is presented in this study. The GSD maps aim to identify high-activity areas and analyze lightning distribution patterns. This was achieved by combining a detailed base map of Peninsular Malaysia with lightning stroke data from Vaisala GLD360 with advanced Geographic Information System (GIS) software. This study has demonstrated the effectiveness of the GSD mapping technique for categorising lightning distribution and locating hotspots during the monsoon season. The total number of lightning strokes in the Year 2023 is 4,405,668 counts, with negative strokes of 3,799,211 counts (86%) and positive strokes of 606,457 counts (14%). The Inter-Monsoon season has the highest average of lightning strokes, occurring in April to May and October to November with the highest peak observed in April until May 2023, consisting of 1,307,170 (29.7% with a total of negative lightning strokes) were recorded based on historical data and the second highest was observed in October to November 2023 with consist of 950,577 (21.6% with a total of negative strokes). The hot spot area identified in the Western region consisted of Putrajaya with 165 strokes/km2/over 1 year (27.4%), Kuala Lumpur with 120 strokes/km2/over 1 year (27.8%), and Selangor with 65 strokes/km2/over 1 year (10.7%). These findings are significant for utility and protection engineers, as they may greatly increase the reliability of electrical networks by lowering the frequency of power outages brought on by lightning strikes.

  • A Compact UHF RFID Tag Antenna for Soil Monitoring
    Muhammad Zamani Ismail, Nabilah Ripin, Mohamad Kamal A. Rahim, Nur Azliza Ahmad
    2023 IEEE International Symposium on Antennas and Propagation Isap 2023, 2023
    UHF RFID technology is currently being chosen to replace the existing soil monitoring system for smart agriculture. However, when attached to backing objects, the current RFID tag typically has a large footprint and a short read distance. Therefore, this paper introduces a compact tag antenna design comprising a slotted radiating patch connected to a ground plane via an inductive stub. The tag antenna is mounted on loamy soil for soil monitoring purposes. The proposed tag has a small size of only 48.2×48.2 mm, a power transmission coefficient of 0.99, and a longer theoretical read range of 9m.

  • In Search of Magnetic Properties of Samarium Cobalt (Sm2Co17) within a Low-Temperature Sintering Process

    Samarium cobalt is known as super high density magnetic material with large magnetic anisotropy energy. Samarium–cobalt exhibits manipulative magnetic properties as a rare-earth material which has different properties in a low sintering temperature. It is therefore of paramount importance to investigate samarium cobalt (Sm2Co17) magnetic properties in the low temperature sintering condition. Sm2Co17, which is utilized in this research, is synthesized via the sol–gel process at sintering temperatures of 400, 500, and 600 °C. Subsequently, the crystallites indicate the formation of a single-phase Sm2Co17 on all the samples in all temperature variations. Moreover, the peaks in the X-ray diffraction analysis of crystallite sizes calculated using the Scherrer equation are 17.730, 15.197, and 13.296 nm at 400, 500, and 600 °C. Through scanning electron microscopy, the particles are found to be relatively large and agglomerated, with average sizes of 143.65, 168.78, and 237.26 nm. The functional groups are also analyzed via Fourier-transform infrared spectroscopy, which results in the appearance of several bonds in the samples, for example, alkyl halides, alkanes, and esters with aromatic functional groups on the fingerprint area and alkynes, alkyl halides, and alcohol functional groups at a wavelength of above 1500 cm. The test results of the magnetic properties using vibrating-sample magnetometer (VSM) revealed high coercivity and retentivity in the samples sintered at 400 °C. However, the highest saturation occurs in the samples sintered at 600 ℃. At a low sintering temperature (below 1000 °C), samarium cobalt shows as the soft magnetic material.

    International Journal of Emerging Technologies in Learning, 2021
    Current students must prepare themselves with the necessary skills for employment in the engineering industry. In addition, students should prepare themselves to work globally. Along with the needs, Shibaura Institute of Technology introduces a program named global Project-Based Learning (gPBL). Malaysian students from different educational backgrounds joined this pro-gram to experience new skills. The program was participated by 34 students from Malaysia and Japan. Current engineering education is focusing on a course that can foster students’ creativity and critical thinking. Therefore, this study explores students’ experiences in gPBL and what student skills developed throughout the program. Students reported their experiences through the self-reflective journal. Then, thematic analysis was used to analyze the students’ self-reflective journals. The results show gPBL promotes thinking and problem-solving skills, encourages students to work with peers in other fields, and encourages students to adapt to a new culture.

    Manganese zinc ferrite is a soft ferrite material that has been used in many applications including catalyst. Therefore, studies on the mechanical and magnetic properties are very important in order to enhance the performance of the catalyst. This study will compare the mechanical and magnetic properties of manganese zinc ferrite (Mn0.8Zn0.2Fe2O4) synthesized by conventional ball milling and self combustion methods. Microhardness Vickers and Impedance Analyzer were used to investigate. Morphology and structure of Mn0.8Zn0.2Fe2O4 were characterized by using X-Ray Diffraction, Field Emission Scanning Electron Microscope (FESEM) and Energy Dispersive X-Ray (EDX). The catalyst characterization was performed using a Temperature Program Reduction (TPR). It has been shown that Mn0.8Zn0.2Fe2O4 synthesized by self combustion method has better mechanical properties (75.83 HVN) and magnetic properties with a superior initial permeability (2.5 × 103) and Relative Loss Factor (0.03) compared to conventional ball milling method. © 2011 Asian Network for Scientific Information
