Authors: Adnan A H M , Karim R A , Shah D S M , Tahir M H M , Shak M S Ya
Published: March 2021

Industry 4.0 manufacturing processes are making advanced hardware and the latest software cheaper, and easier to employ for teaching and learning. In the process, the objectives of the Higher Education 4.0 initiative are being realized. Tertiary educators should take heed of these developments so that their undergraduate students could benefit from education technologies that are geared for the current technologically savvy generation. The question that needs to be asked is, are tertiary educators taking advantage of innovative teaching and learning technologies by becoming content developers? And, are they deploying educational materials that align to the principles of Higher Education 4.0 for the advantage of their tertiary students? This empirical paper reports and discusses findings from a survey on content development and materials deployment by Malaysian tertiary educators from different fields across a range of tertiary institutions in Peninsula Malaysia. Results do not look encouraging. Some respondents stated that they do use high-end learning materials in teaching and learning, just not content that they have created on their own. Only a minority are taking advantage of new technological tools to create their proprietary immersive and interactive materials, a finding that might be the case for many developing nations across the globe.

Published: March 2021

Industry 4.0 is a time of serious disruptions whereby monumental changes are happening in the world of work, in the ways we teach and learn, and in the ways that we live our lives. Increased automation coupled with artificial intelligence are making humans obsolete, for instance, in the manufacturing and service industries. Intelligent machines are useful but human beings are losing livelihoods or becoming trapped in the ‘gig economy’. This empirical study collected and examined qualitative data related to Industry 4.0 critical skills outlined by the World Economic Forum from ASEAN student leaders at five tertiary polytechnics in Brunei, Indonesia and Malaysia. ‘Netnography’ data collection instruments were employed namely online interviews and group discussions within a cloud-based instant messaging and VOIP service together with face-to-face focus group discussions, where permissible. Results do not look too promising with a number of the participants still in the dark about what skills they need to acquire for Industry 4.0 and how they must hone those skills before they enter an uncertain world of work in 2020 and beyond. Clearly, ASEAN nations must move fast, un-train and retrain tertiary students in the vital skills needed to survive and succeed in the post-Industry 4.0 era.

Published: March 2021

Deep underground infrastructure is booming technology in developing countries, and these construction techniques are mostly used in developed countries at present. Pile foundation among many types of deep structures, it is significantly researched and built to sustain and transfer loads from superstructures to deep soil, in either case, the load from the superstructure is very high or the soil at shallow depth is too weak. Piles are subjected to axial, horizontal, momentary, and combined loading systems as a single pile or pile group system connected to the reinforced pile cap on top of the pile to share or transfer loads through the wall and tip to the surrounding soil. Along with elastic solid pile-pile cap characteristics of materials, a limited number of numerical and analytical studies are published even merely on a homogeneous soil placement of the pile cap model. However, The soil’s natural deposit at a significant site may not always be found homogeneous on which pile-caps and piles are placed. To fill the gap of an intricated multi-physics soil-structure interaction problems, successive analysis is incurred to be proliferated. The study presented a numerical analysis of the influence of the pile cap on the single laterally loaded pile, while the embedding of the pile cap varied on the layered soil profile. The standard linear static numerical analysis software ABAQUS was used to model 3D pile cap-pile and layered soil with subjected lateral load and relevant boundary conditions. The result of the analysis was plotted varying the embedding of the pile cap on clay overlaid sand and sand overlaid clay interchangeably taking into consideration other influencing parameters (pile capsize and vertical load). The increase in pile cap embedment on clay overlaid sand slightly increases the lateral resistance of the pile cap for the first few increments and small non-linear variation for further embedding from the analysis has resulted. However, the performance of the pile cap for lateral load resistance was significantly increased as the depth of embedding of the pile cap is increased on sand overlaid clay. Besides, the size of the pile cap has a direct proportion for lateral resistance, and the vertical load exerted on a pile cap has not had a significant influence. The study comprehensively emphasized the interaction of piles with simple soil physics problems, but multi-soil physics problems with pile interaction should be analyzed for future study.

Fatty acid methyl ester (FAME) or biodiesel is alternative source for diesel fuel due to its renewability and environmentally friendly nature. In this study, mixed oxides catalysts of Cr-Ti were synthesized by using sol-gel method and used in transesterification of cooking palm oil (CPO) in a batch process to produce FAME. The effects of metal ratio and aging time were studied. The metal ratio Cr:Ti of 1:1, 1:2, 2:1, 0:1 and 1:0 and aging time between 1 day and 5 days contributed effects on the FAME density obtained from the reaction. The catalyst characteristics in term of surface area, pore size, pore volume and thermal stability were also affected by the various metal ratio and aging time during catalyst synthesis. The results show that Cr-Ti catalyst prepared at 2:1 metal ratio and 5 days aging time exhibit FAME density of 854 kg/m3, which is within the value range of biodiesel fuel property. The catalyst has surface area of 45.88 m2/g, pore size of 190.52 Â and pore volume of 0.1984 cm3/g sufficient to promote efficient heterogenous catalytic activity and has good thermal stability. Thus, Cr-Ti mixed oxides has potential as heterogeneous catalyst to produce FAME from the transesterification of CPO.

Published: March 2021

This study explains the added value of the North Sumatra Langkat limestone and its derivative products. Limestone is classified as high calcium, characterized by its high calcium oxide (CaO) content of 38.39% -55.84%, its physical characteristics show dark gray color, dominant calcite, smooth, hard and fossilized texture. So far, the use is in the form of chunks, especially as a raw material for building which gives a low value to the limestone. The 3 limestone samples SK5, SK7 and SK8 were calcined to obtain quicklime and hydrated lime products with different temperatures of 900°C-1100°C. Limestone SK7 and SK8 CaO content increased 59.7% and 66.08% respectively and were light white compared to SK5 55.8% and colored brownish gray. To produce hydrated lime, it is done by adding / soaking with water (H2O) to the quicklime to produce a heat rate of hydration (slaked). SK8 limestone shows an optimum temperature increase of 74.6°C for 75 seconds compared to SK7 and SK5 limestone 50.2°C and 48°C respectively at 900°C combustion temperature. The heat transper occurs on the outer side of the limestone, then spreads to the limestone body. The difference in hydrated heat in the limestone is due to the presence of mineral impurities and non-uniform grain size so that the heat obtained is not perfectly distributed. The impurities such as SiO2, Fe2O3, Al2O3 and MgO contribute to the product quicklime and reactivity of these samples. Besides the quicklime and hydrated lime products, the added value of Batumilmil limestone is derived by making ground calcium carbonate (GCC). The GCC product is fine mesh size of 60 mesh - 400 mesh ultrafine, with high calcium quality and bright / bright color. The increase in added value added from limestone products contributes to the selling value and various applications in the industrial sector.

This study aimed to examine the effects of unilateral versus bilateral resistance training and bilateral deficit on unilateral and bilateral strength adaptation among trained men. Thirty recreationally active, resistance trained men were recruited and were divided into three groups; i) unilateral (n=10), ii) bilateral (n=10) and iii) control (n=10). Chest press and biceps curl strength tests were conducted unilaterally and bilaterally before and after six weeks of training intervention. Unilateral bicep curl and chest press training was given to the unilateral group while the bilateral group was asked to undergo bilateral bicep curl and chest press training. 1RM bicep curl and chest press tests were measured unilateral and bilateral strength and bilateral deficit before and after the intervention. The intervention period were six weeks. Mixed design (ANOVA) was used to compare strength during pre- and post-test in groups while MANOVA was used to compare the changes in percentage during pre and post-test between groups. Results showed a significant difference in the test of unilateral strength within groups. Both unilateral and bilateral training groups managed to improve both unilateral and bilateral strength significantly in both exercises but there was a decrease in unilateral and bilateral strength within control group. On the other hand, all the three groups showed no bilateral deficit for bicep curl and chest press test. The findings also revealed that there was a significant difference in the percentage changes between groups. The unilateral group showed a greater change in percentage the in unilateral strength compared to the control group but no significant difference with the bilateral group. While, the bilateral group showed a greater percentage change in bilateral strength compared with the unilateral and control group. In conclusion, this study showed that both of these unilateral and bilateral exercises can increase muscle strength in trained men. However, the unilateral and bilateral strength adaptation is specific to the training performed especially for multi-joint and complex exercise.

Published: March 2021

Front strut bar is an automotive part commonly used for McPherson suspension system to minimize load on the strut tower by tying both left and right strut with a single bar. By distributing the force acting on a single strut to both strut tower, the strut bar minimizes the chassis flex which improves ride and handling especially during cornering. Therefore, strut bar should be stiffer but lighter at the same time to reduce vehicle weight towards fuel efficiency and lower carbon emission. This research attempts to design a lightweight carbon fiber reinforced polymer strut bar to replace conventional steel strut bar with equivalent stiffness. For validation, a steel strut bar model is analyzed by conducting experimental modal analysis to determine their natural frequencies and the corresponding mode shapes. These results were compared to simulation results. Later, the dynamic behavior of CFRP and the equivalent mode shapes were analyzed and correlated with static loading test results. Combination of different ply orientation and stack sequence results in the design of an optimized carbon fiber strut bar achieved 48% reduction in weight, up to 40% higher natural frequency while improving or preserving the static and dynamic performances compared to the steel strut bar.

The influence of annealing temperatures exercise upon the microstructure, texture and earing of cold-rolled sheets was analysed by means of ODF texture analysis, EBSD technology and cup drawing test. The results show that the contents of the deformed microstructure, the recrystallized structure and the substructure change sharply annealing at 300°C, but they tend to be stable at 350°C. The starting temperature of recrystallization of 8011 cold-rolled plates is about 300°C. When cold rolled sheets were annealed at low temperatures, there were quantities of grain boundaries whose angle was small. When the annealing temperatures were higher, the small and medium angle grain boundaries of the cold rolled sheets decreased gradually. The general trend was that the small angle grain boundaries first increased and then decreased as the case of annealing temperature rise. The proportion of the small angle grain boundaries reached to the minimum value of 20.2% at 350°C. When annealing temperature is 350 °C, the lowest earing rate is 2.11%.

Epoxy resin adhesive have many advantages that other adhesives do not have, and are widely used in various fields. At the same time, it is also a thermosetting resin with high crosslinking density. Its cured product is brittle, low impact strength, and easy to crack. These shortcomings limit the further application of epoxy resin. This article takes the plugging agent of UDMH as the starting point. Epoxy resin adhesive toughened and modified with two kinds of inorganic fillers, nano-titania and micro-alumina, were prepared and study the compatibility of modified epoxy resin adhesive with UDMH. It is found that under certain conditions, the silane coupling agent KH570 can undergo a grafting reaction with the hydroxyl groups on the surface of nano-TiO2 to improve its lipophilic and hydrophobic properties, and the effect is better than KH560, KH550; Through FT-IR, SEM, TG and other characterization methods, it is found that when the content of coupling agent is 15%, the effect of surface modification is the best. In the preparation of two kinds of inorganic filler modified epoxy adhesives, it is found that when the content of nano-TiO2 is 3%, the toughening effect is the best, and the impact strength can reach 36.78 KJ/m2; When the content of micro alumina is 60%, the toughening effect is best, and the impact strength can reach 28.43 KJ/m2. In general, the toughening effect of using nano-TiO2 is significantly better than that of alumina. In the study of the compatibility of the two kinds of filler modified epoxy resin adhesives with UDMH, it is found that when nano-titanium oxide is used as the filler, the compatibility of epoxy adhesive and UDMH is improved. However, when micro-alumina is used as the filler, the compatibility of epoxy resin adhesive and UDMH becomes worse.

HZ belt conveyor is a rubber conveyor belt with an end (or no end) installed on the driving roller and driven roller at both ends of the conveyor. Several parallel rollers and pallets are installed between the two rollers to support the weight of the material and the conveyor belt. The selection of the entire hardware of the balance control system of the belt conveyor is very important. In addition, the quality of the designed program (including the control algorithm and control accuracy) will directly affect the control performance index of the control system, and even affect the stability of the system. Therefore, in addition to hardware, program design is an important part of all links. The system designed in this paper is mainly designed by Siemens PLC300 special software STEP7.

During the rotation, aero-engine impeller blades are subjected to the alternating load of high frequency, low stress and small strain, so it is effortless for the impeller blades to enter the stage of very-high-cycle fatigue (VHCF). The research on the VHCF performance of 2A60 aluminum alloy is of great engineering significance to verify the reliability of the impeller in service. In this paper, the VHCF performance of 2A60 aluminum alloy is studied by fatigue life curve and fracture morphology. The results show that the fatigue properties of 2A60 aluminum alloy under different cooling conditions are different, and the VHCF properties under ethanol cooling conditions are better than those under water cooling conditions. However, under either water-cooled or ethanol-cooled conditions, the fatigue fracture mode of 2A60 aluminum alloy is single, showing a surface crack initiation mode, and the S-N curve shows a continuous downward trend without the intermediate platform. The VHCF crack originated from the stress concentration on the sample surface and the cleavage fracture occurred in the grains near the crack source in the early stage of crack initiation. The VHCF process of the sample is also the relaxation process of its residual stress.
