| 951 | 2024 Article | Nanosheet zinc oxide synthesized by solution-immersion method for triboelectric nanogenerator Suriani Abu Bakar Most global problems are being solved by using sustainable energy harvesting technologies to retain the social ecosystem in great condition. The triboelectric nanogenerator (TENG) which is a renewable energy harvesting device, collects the waste mechanical energy from its surroundings and performs the electric signal conversion. TENG have garnered increased attention in recent years by offering prospective use in energy harvesting technology. Particularly, there is a need for flexible energy conversion that serves as a power supply for portable electronic equipment. In this study, ZnO nanosheet thin film prepared on the flexible conductive aluminium foil through a low temperature immersion technique was used to generate electrical energy. The effect of heat treatment on ZnO nanosheet thin film was also investigated on the surface morphology, structural properties and nanogerator performance. The high density of interconnected ZnO nanosheet were observed before and after heat treatment ..... 107 hits |
| 952 | 2024 Article | Fabrication and characterization of a novel mullite-stainless steel composed hollow fibre membrane for oil/water separation Suriani Abu BAkar Low-cost mullite-kaolinite material has recently received more attention as an alternative to conventional ceramic materials such as alumina and silica to prepare ceramic hollow fibre membranes (CHFMs) due to its high alumina contents and silica and thermal/chemical stability. However, weak bending strength is still one of the key bottlenecks that delay their commercial applications. In this work, we successfully fabricate a novel mullite-SS HFM with enhanced bending strength using mullite-kaolinite power with different stainless steel alloy (SS) 316 L contents of 0.0, 2.5, 5.0, 7.5, 10 and 12 % (w/w) as a reinforcement material by phase inversion/sintering techniques. The SS alloy was a potential material to enhance the mechanical strength of mullite HFMs due to its excellent mechanical properties. The effects of the major fabrication parameters of SS contents, mullite contents, and fabrication parameters such as air gap distance and bore fluid flow rates were well studied and evaluat..... 46 hits |
| 953 | 2024 Article | Game-based learning: Current practices and perceptions of secondary school physics teachers in Malaysia Balakrishnan, Balamuralithara A plethora of studies showed the effectiveness of game-based learning (GBL) in enhancing students’ learning and motivation. There has been increasing academic interest in GBL. However, a review of past literature in this context shows that teachers’ attitudes, in general, toward GBL and the actual adoption of GBL in teaching physics by secondary school teachers in Malaysia have not been addressed in-depth or addressed only to a minor extent in past studies. This article sheds new light on secondary school physics teachers’ perceptions of GBL usage, the implementation level of GBL in teaching physics, and teachers’ involvement in educational games design. A total of 211 secondary school physics teachers participated in this study. Quantitative data were collected via survey, and the main findings show that only 29.9 percent of teachers designed educational physics games and adopted the games in teaching physics. The implementation level of GBL in teaching physics at the secondar..... 98 hits |

Sports performance is a complex mixture of biomechanical function, emotional factors, training techniques, tactics, and many other aspects. Objectives. This research aimed to examine the muscle activation of compound archers during shooting. Methods. Twenty-four compound archers, consisting of 10 males and 14 females, who met the inclusion criteria were included in the study. Athletes were divided into three according to their shooting score. A wireless surface EMG system (Trigno EMG sensor, Delsys Inc., USA) measured activity on the middle deltoid, posterior deltoid, middle trapezius, lower trapezius, triceps, and anconeus muscles. The measurement was recorded of nine shots, and the distance between the archers and the target was 18m. Results. There was no statistically significant difference between the elite, intermediate, and junior compound archers. No significant difference was found between the genders u..... 106 hits |
| 955 | 2024 Article | Recycling roads: A teacher’s journey in Malaysian preschools' ecoeducation Iylia Mohamad Recycling is not yet a common practice for everyone, but it is crucial for protecting the environment. According to the National Solid Waste Management Department (NSWMD), only 31.52% of Malaysians participate in recycling, which falls short of expectations. This figure is notably lower than the rates of other developed countries, which typically exceed 60%. These statistics indicate that Malaysia still has significant progress to make in recycling efforts. However, the nation aims to reach a 60% recycling rate by 2025. Although achieving this goal may seem challenging, there is a strong commitment to making it happen. This study focuses on educating young children about the benefits, challenges, and innovations of recycling. The study involved six children from a government preschool as the primary participants. To make learning more engaging, traffic road play was used as a tool to promote recycling. Data was collected through a qualitative approach within an action research framewor..... 202 hits |
| 956 | 2024 Article | Exploring the use of Kahoot! to monitor learning performance among students in higher education Singh, Charanjit Kaur Swaran Gamified educational applications have proven to be practical tools for teachers, particularly in second language (L2) instruction, as they can enhance student interest, motivation, and assessment outcomes in online sessions. Despite these benefits, however, many higher education institutions rely on traditional teaching methods, mainly because of the challenges associated with maintaining student motivation throughout online learning sessions, a critical factor for successful learning outcomes. The aims of this study are to further understand the use of gamification in teaching and learning, particularly with large audiences during online classes, its impact on learning performance, familiarisation, active learning, formative learning, and student attitudes. Utilising a mixed-methods research design, 177 students participated in a survey, while 10 were interviewed for triangulation. Validated by three experts, the instrument demonstrated a reliability coefficient of 0.81. The results ..... 70 hits |
| 957 | 2024 Article | Authentic assessment practices of geography teachersin the online education Hanifah Mahat This study aimed to determine the professional duty of Malaysian geography teachers to integrate authentic assessment into the teaching and learning process. Questionnaires were distributed online to 379 geography teachers at the secondary school level by a simple online snowball distribution method.

| 959 | 2024 Article | Formulation of nanoemulsions from cerbera odollam seeds essential oil and their larvicidal activities against aedes aegypti larvae Azlan Kamari As of September 2024, there are 322,274 and 94,807 cases due to dengue in Indonesia and Malaysia, respectively. Prompt actions must be taken to control mosquito population and mosquito-borne diseases proliferation. Larvicidal control is one of the effective strategies that are promoted by World Health Organization (WHO). Bintaro (Cerbera odollam) are highly available in wetlands, but they are extremely toxic, especially their seed kernels. In this study, the active compounds of C. odollam seed kernels were gradually extracted using Soxhlet extraction with n-hexane, chloroform and ethanol and were further distilled with a rotary evaporator. Nanoemulsions were formulated with Arabic gum and Triton X-100 by using both homogenisations of high-speed and ultrasonic. Gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared (FTIR) spectroscopy and scanning transmission electron microscopy (STEM) were used to characterise oils and nanoemulsions.

| 960 | 2024 Article | Assessing the size of shadow economic activity in Malaysia based on the modified money demand model approach with structural break Gamal, Awadh Ahmed Mohammed This paper aims to address those methodological issues by exclusively applying the newest modification to the Money Demand Model (MDM) in the form of the autoregressive distributed lag (ARDL) approach to estimate the Malaysian shadow economy (SE) from 1985 to 2020. Methodological errors and spurious regression issues hindered earlier studies on the Malaysian SE. Some studies included Malaysia in their analyses alongside other Asian countries with similar levels of development, without accounting for the distinct economic environments of these countries. This study accounts for the influence of economic uncertainty (EU) and structural breaks. The study finds that Malaysia's SE averaged 40.8% of its official gross domestic product (GDP), peaking in 1995–1996, after which it gradually declined and stabilized around 39.4% of GDP. This substantial size highlights the critical need for tailored economic policies to manage SE growth effectively. The findings not only provide a clearer under..... 126 hits |
