This investigation analyses spotlight components to reduce the necessary amount and explore the potential to enhance the sustainable design. The DFMA and Sustainability design considerations for manufacturing assemblies were used and incorporated in this work. DFMA outcome displays that components were reduced while the LCA showed that weight, carbon footprint, acidification of the air, water eutrophication and overall energy consumption were reduced. This new approach is essential for demonstrating the efficiency of both tools used to reduce the cost of spotlight manufacture and enhance the sustainable aspects of product design.

Housing is one of the eight domains of the concept of age-friendly cities or environments of the World Health Organization (WHO). A healthy community ensures the availability of safe, decent, and affordable housing that supports the health of its occupants. Human spends more than 50 percent of his time inside the house, studies have shown that the built environment can affect human health. The unhealthy house can cause many diseases. Unhealthy houses increase the number of asthma, respiratory and skin allergies and lung diseases. Also accidents and domestic injuries are more in these houses. In addition unhealthy houses affect mental and social well-being such as: depression, isolation, stress and behavioral abnormalities. The “Healthy House” is not just designing healthy and hygienic shelter, but also includes complete physical, mental and social well-being in the house and the environment. Thus, the purpose of this paper is about information on creating a healthy home environment in Malaysia.

The aim of this paper is to investigate the impacts of education levels, genders and age on employees’ internet use in Malaysia during the Movement Control Order (MCO) in Malaysia. An online survey was used to collect primary data from 505 internet users among employees from public and private organizations in Malaysia. Data collected were analysed using SPSS 20.0. The results indicated that gender and education level had a positive impact on employees’ internet usage while age did not have any significant impact on employees’ internet usage. These findings should be useful for policymakers in setting up strategies to promote internet use among employees. Implications of the study are also discussed.

Immiscible polyurethane elastomer (PUE)/silicone rubber/graphene nano-platelets blend composites filled with different PUE/silicone rubber blend ratio were synthesised by using solution casting technique. In this work, two different types of silicone rubber: liquid silicone rubber (LSR) and powdered silicone rubber (PSR) were used as secondary matrix based on double percolation concept to construct an immiscible blend that has a balance electrical conductivity and mechanical properties. The electrical conductivity has increased gradually, but the mechanical properties of the composites shows a remarkable decline when silicone rubber loading increases up to 20 vol% for both blend systems. The well balance of electrical conductivity and performance is achieved at 15 vol.% of silicone rubber loading. Overall, PUE/PSR/GnPs at 15 vol. % of silicone rubber content has higher electrical conductivity and mechanical strength as compared to PUE/LSR/GnPs blend system.

Ba0.9995La0.0005TiO3 ceramics prepared via solid-state reaction route was found to be phase pure at the final sintering temperature of 1300°C for 16 hours. The dielectric constant was varied from 1900 to 2800 from 10 Hz to 100 kHz. Impedance spectroscopy is a powerful technique to study the complexities of ceramic materials such as homogeneity and inhomogeneity of materials that being process during production of most electronic materials. An electronic ceramic component can be visualized as a grain, grain boundary and electrode system. Impedance spectroscopy is being widely used to separate out contribution of the bulk and the grain boundary to the overall equivalent circuit models. Fixed frequency plots of dielectric constant versus temperature for Ba0.9995La0.0005TiO3 ceramics shows typical perovskite response with Curie temperature, Tc about 115 °C and fit with the equivalent circuit which contributed by bulk and grain boundary response.

The role of design and innovation through NPD process can be a good platform for Malaysian SMEs to enhance their competitiveness. However, less study has been conducted to examine how the process has been implemented by SMEs. NPD process requires a proper planning and commitment from the company. Managing the NPD process by utilized design as a source of innovation will improve the quality of the product. But, many of the SMEs not utilize the potential of design and innovation as their sources to gain competitiveness. Therefore, there are gaps on how the process has been conducted by SMEs such as how they implementing, managing and who are the parties should be involved in the process. The objective of this paper is to explore the process of new product development conducted by small and medium manufacturing industries (SMEs) through design and innovation in creating added value to a product, based on an empirical study covering product, furniture, and automotive manufacturing industries in Malaysia. A mixed-method was applied consist of 450 respondents for questionnaire survey and 12 selected participants from different group’s namely industrial designers, marketers, and decision-makers. The results reveal the positive effects of managing design and innovations in the industries are important to improve product value and to enhance company performance through product development processes.

The high silica content in fly ash (FA) and palm oil fuel ash (POFA) can be utilized as the main material of cement substitution. In this study, the geopolymer mortar made by mixing alkali activator Na2SiO3 and NaOH as activator and fly ash and palm oil fuel ash as precursor. Variations in the ratio of FA and POFA with the value of 75:25, 50:50 and 25:75. As well as the ratio of the alkaline solution between sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) of 1.5, 2.0, and 2.5. The objective of this study is to know the effects of NaOH and Na2SiO3 ratio to compressive strength on geopolymer mortar. The result of compressive strength test showed that the maximum compressive strength of mortar of 28 days was obtained by 22.08 MPa using alkali activator ratio of 2.5 with FA75:POFA25 and the minimum compressive strength obtained from comparison of FA25:POFA75 with alkali activator ratio of 1.5 was 3.7 MPa. It was showed that the use of FA75:POFA25 precursor and the greater alkali activator ratio used, the higher the compressive strength obtained. Further research will be developed to explore the potential of oil palm fuel ash based geopolymer concrete.

Evaluation of laboratory experiences of engineering and engineering technology students has led to an increasing in the attention being paid to the development of students’ psychomotor skills. One of the reasons that psychomotor seems to be less important in the past is because of the lack of suitable measuring tools despite it is important in the engineering and engineering technology course. Furthermore, a current assessment which is using report and test to evaluate the experience of student practice in the laboratory only help in assessing students’ knowledge in cognitive skill. Thus, a new study method is needed to focus on evaluating engineering technology students in terms of their understanding of the component called ‘hands-on practical experience’ during their practical skill classes or experiment. The existing technique for evaluating psychomotor abilities that have emerged from attempts to improve selection in recruitment processes may provide a potentially useful tool for such a purpose. The point of this study is to create a new approach to test a change in practical experience to assess unintentional learning related to classic psychomotor skills in engineering technology laboratory classes. The methodology used to build up the instrument is portrayed and the empirical data collected to support its validity is presented. Thus, this research aims to find a way to measure the practical skill involve in a psychomotor change in an engineering laboratory class.
