DEVELOPMENT OF SOLAR COOKER USING PARABOLIC REFLECTORS
Full text linkFor cooking we generally make use of gas which is a commercial source. Solar energy is a renewable and non-commercial source which is adequately available for usage. So the idea of making use of solar energy to cook brought the existence of solar cookers. But the main problem with the model with it is, it is not effective during day start and end because rays cannot incident completely over it. So it takes more time to cook. So to overcome this issue, usage of a parabolic reflector is the solution where the incident rays meet at the focus which generate more heat and results in faster cooking that saves time
BLUETOOTH OPERATED SCISSOR JACK: THE FUTURE OF VEHICLE LIFTING EQUIPMENT FOR DEVELOPING COUNTRIES
Full text linkThe tire exchange process can be a daunting task for people with limited abilities. As the physical effort required for the conventional vehicle jack operation can be difficult or impossible for some people. Hence, manufacturers have developed electrical scissor jacks that can be controlled remotely. These jacks eliminate the need for exerting any physical effort so that people with limited abilities can change their own tires. However, commercial electrical jacks are expensive, not always available in developing countries at reasonable prices. Moreover, they are controlled using a wired remote-control device and powered by connecting alligator cables to the vehicles’ battery. This paper presents the procedures needed to convert a manual commercial scissor jack to a smartphone-controlled one using developing country local market components. The jack is controlled via Bluetooth connected device and can be powered by the vehicle's cigarette lighter receptables, alligator cables, or AC power outlet. In addition, emergency buttons are attached to the control unit in case smartphone application suddenly malfunctions during the lifting process. The prototype was successfully tested and was able to lift a vehicle 25 cm in less than two minutes. This is a significant improvement over manual jacks, which can take up to four minutes to lift the same distance. The proposed smartphone-controlled scissor jack is a valuable tool for people with limited abilities, as it makes the tire exchange process much easier and faster. The low cost and local availability of the components make it a viable option for developing countries
EFFECT OF VARIOUS FIBRE LOADINGS OF PINEAPPLE LEAF FIBRE ON POLYLACTIC ACID COMPOSITES FILAMENT
Full text linkRecently, natural fibres have been widely utilized because they are firmer and have higher strength comparable to synthetic fibres. Every fibre has various properties, and polymer composites reinforced with natural fibre are known to have superior mechanical properties. In this study, the pineapple leaf fibre/polylactic acid (PALF/PLA) composites filaments are developed with several processes, including grinding, sieving, chemical treatment, and hot compression on the composites with various fibre loadings of 1, 3, and 5%, continued with the crushing and the extrusion processes. Then, mechanical testing for specific flexural and tensile testing was conducted on the PALF/PLA filament composites. The findings showed that the PALF/PLA composites with a 5% fibre loading exhibited the highest mechanical properties in both flexural and tensile properties. In conclusion, 5% fibre loading of PALF/PLA composites filaments can be used as an alternative material to replace pure PL
DEVELOPMENT AND EVALUATION OF ASBESTOS-FREE BRAKE PADS PRODUCED FROM COSTUS AFER WASTE AND LOCAL GUM ARABIC
Full text linkThis study dealt with the development and evaluation of a new asbestos-free non-carcinogenic brake pads with Costus afer waste (CAW) particle as the base material. Three sets of brake pads with different sieve sizes (90, 100 and 200 µm) were developed, through compression molding from a 55% CAW particles, 22% local gum Arabic as binder, 5% of rubber seed husk and 5% of walnut shell as fillers, 10% iron filling as frictional addictive, 1% of carbon black as friction modifier, 1% of cobalt nepthanate as catalyst and 1% of Methyl ethyl ketone as accelerator. Physico-mechanical test were carried out on the CAW-based brake pad with a Brinell hardness test value of 103HB and density of 1.3 g/cm3 which is far better than the commercial available brake pad upon comparison. These properties were found to increase with a decrease in particle sizes while the water absorption, oil absorption, wear rate, and flame resistance increased with increasing particle sizes due to enhanced porosity. The developed CAW-based brake pad especially with the grain size of 90µm, shows a better wear performance as compared to the control commercial brake pad. The overall results of the evaluation were further compared with similar asbestos-free brake pad in literature. The study can conclude therefore that the CAW-based brake pad stands as a better replacement for the existing commercial asbestos-based brake pads

Full text link(Work-Life Balance to Increase the Job Satisfaction of Academic Members at Universiti Teknikal Malaysia Melaka: A Review)ABSTRAK Keseimbangan di antara kerja dan kehidupan adalah penting bagi seseorang pekerja, khususnya dalam kalangan ahli akademik. Pada masa sekarang cabaran dalam menyeimbangi di antara kerja dan kehidupan adalah mencabar. Jika seseorang itu memberikan lebihan perhatian pada suatu sisi samada kerja mahu pun keluarga, satu sisi lagi pasti akan terabai. Apabila permintaan kepada kerja atau urusan peribadi diperlukan ia secara langsung mewujudkan situasi yang tidak seimbang seterusnya membentuk konflik kerja dan keluarga. Konflik keseimbangan antara kerja dan kehidupan akan memberikan kesan negatif kepada pihak lain samada organisasi mahupun kepada keluarga. Kegagalan menguruskan keseimbangan di antara kerja dan kehidupan dengan baik akan memberikan kesan yang negatif antaranya ketidakhadiran kerja, kurang komitmen di tempat kerja, kualiti kerja rendah, produktiviti rendah, kurang kreativiti dan inovasi, tekanan, konflik di dalam keluarga, dan penceraian Oleh itu kajian ini akan menganalisis soroton kajian lepas berkaitan dengan definisi keseimbangan kerja kehidupan dan juga elemen-elemen keseimbangan kerja kehidupan dalam kalangan ahli akademik UTeM. Dapatan kajian daripada soroton kajian lepas ini akan dapat membantu penyusunan idea yang lebih sistematik dan signifikan ke arah kajian yang akan datang. Kata Kunci: keseimbangan kerja kehidupan, kepuasan kerja, ahli akademik ABSTRACT Work and life balance is important for an employee, especially among academics. Nowadays the challenge of balancing work and life is challenging. If a person gives too much attention to one side, whether it's work or family, another side will definitely be neglected. When demands for work or personal affairs are needed, it directly creates an unbalanced situation and further forms a conflict between work and family. The conflict of balance between work and life will have a negative impact on the other party, whether it is the organization or the family. Failure to manage the balance between work and life well will have negative effects including absenteeism, lack of commitment at work, low work quality, low productivity, lack of creativity and innovation, stress, conflict in the family, and divorce. Therefore, this study will analyze the highlights of previous studies related to the definition of work-life balance and also the elements of work-life balance among UTeM academics. The research findings from the highlights of this past study will be able to help organize more systematic and significant ideas towards future studies.

Full text linkABSTRACT The borderless and dynamic globalization environment has forced universities to operate in a more complex and competitive higher education landscape. Hence, it is important for universities to function as learning organizations to ensure their survival, be resilient and achieve sustainable growth especially in the era of Industry 4.0. This study, which used the case study method involving Malaysian public universities, intended to investigate the implementation of learning organization practices as main drivers. Data were collected by conducting interviews involving eight respondents from each university and were analysed qualitatively. The study sample comprised three categories of human resource personnel, namely executives, management staff and academic staff. Findings show that the universities had managed their three subsystems, namely leadership, work system and structure, as well as resilient performance and staff development, at different levels. Among the three subsystems, work system and structure were identified to be at the highest level, followed by leadership and finally, resilient performance and staff development. The seven learning organization practices which were information flow, organizational climate, individual/group development, individual/group practices, vision and mission staff achievement and feedback found to be main drivers among the human resources personnel. Conversely, five practices that were yet to become common learning organization practices were executive practices, work systems and organizations, training and education, management practices, as well as reward and recognition. Universities that function as learning organizations assume learning to be a catalyst for the development of resilient human resources. Therefore, the university is able to survive and sustain its dynamics in a competitive environment in a higher education system, especially in the era of Industry 4.0. This paper may have some direct implications towards the industrial 4.0 (IR4.0) movements in Human Resources in Malaysia which able to provide new insight into the exploration of the idea through the practice of learning organization.
