Abstract: Technical training instructors play an important role in shaping students with value of employability and high workability. Human capital development of vocational instructors produce quality students who fulfil industrial requirements and in line with the national agenda towards highly skilled workers. Based on the Malaysia’s Development Plan of Occupational Skill, the issues and challenges that have been identified in producing skilled workers development is a matter of less competent trainers in interpersonal and technical skills. The objective of this study was to identify and analyze the development of technical instructor for giving consultancy services to the industry. Development of technical training instructors have been formulated through Community Employment Support Services to build collaboration between the community, technical institutes and industry using three main concept or tools: Employment Support, 5S Kaizen and Curriculum Development Based on Ability Structure. The role of employers in providing training and education to employees is vital in establishing career development of employees. Employers who contributed to their employees' training funds through Human Resources Development Council would provide opportunities to increase the skills of workers. The biggest impact on high skills is customer satisfaction and increase in organizational productivity.

Abstract: Although the advancement of technology can provide a better and safer working environment to people, sometimes, overconfidence in technology can lead to unavoidable accidents and human errors in the workplace. This study aims to determine the effects of familiarity with office equipment on human errors and accidents in the workplace. A total of 150 surveys were collected and analysed with correlations analysis usingSPSS software version 19.0. The results show that although familiarity can reduce the occurrence of human errors, it cannot reduce the occurrence of accidents in the workplace. While it is now understood that improving one's familiarity with office equipment can potentially reduce their mistakes at work, companies should still be observant of other factors that can potentially reduce accidents in the workplace. This study sheds light on potential possibilities to improve the occupational safety, health and environment of organizations.

Abstract: This paper provides a critical analysis on the impact of world-class manufacturing practices on company performances in the manufacturing sector based on a survey conducted on various manufacturing companies in Malaysia. The result gathered was used to developatheoretical framework that will be used to investigate whether the quality, cost, delivery and flexibility may affect the performance of bottom line in these manufacturing companies.The theoretical framework is also formed based on a comprehensive review of existing manufacturing management literature to propose the “World Class Manufacturing (WCM) Framework" to achieve manufacturing excellence.It is a combination of these three approaches which offers complementary outputs, which form the basis for pursuing superior performance in manufacturing.This paper presents the WCM Framework and addresses the possible synergy of concurrent application of TQM, JIT and TPM. A discussion of the various practices used in the Framework provides not only guidance on how to implement the Framework, but also an instrument to measure the status of its implementation. It is expected that the concurrent application of TQM, JIT and TPM, via their accompanying practices, may bring about significant improvements in quality, cost, delivery and flexibility.

Abstract: With the ever competitive global market swamped with more choices of high-tech gadgets from smartphones to head-mounted display eyewear like “Google Glass”, Information and Communication Technology (ICT) is one of the key factors to engineering and technological advancement and the bridge to the future. In view of such significant importance, the government of Malaysia has been embarking on national policies to prioritise the education and the programmes on ICT to train and produce highly skilled ICT workers to achieve the nation’s ambition to become a developed country. Despite the government efforts, studies have shown that Malaysia is still currently facing shortage of skilled ICT workers. In view of this shortage of skilled ICT worker problem, a systematic engineering problem solving theory known as TRIZ is applied to generate ideas and potential solutions to solve this problem in this research.

Abstract: The shortage of material and environmental legislations have encouraged car manufacturers to recycle used material in end of life vehicles (ELVs), reverse logistics are essential to the concerns of the automotive supply chain. In this research, a profit model multi-echelon reverse logistics network including collection center, shredder center and recycling center is developed to recycle automotive parts. The work was continued by illustrating empirical application in wiring harness manufacturer that would like to recycle wire harnesses and extract copper. With regards to the complexity of the reverse logistics network, traditional method cannot be implemented for solving them. Thus, an evolutionary algorithm based genetic algorithm (GA) is applied as a solution methodology to solve mixed integer linear programming model and find the optimum solution. The results emphasize the efficiency of the modeling and solving method so that in the case study the company gained more than 27 thousand dollars through the establishment of reverse logistics for recycling copper.

Abstract: Malaysian industries, in general consider energy management a burden and non-profitable. Energy management initiatives are also viewed as a Cost-Centre. An Excel spreadsheet was therefore tailor-designed, which meets the requirements of the plant for energy optimization and management. The spreadsheet is grouped to reflect four parts, namely: plan, do, check and commit. This Plan-Do-Check-Commit cycle is based on the plan-do-check-act (PDCA) cycle. This spreadsheet has been developed with the objective of developing a tool that would be comprehensive, simple and flexible, open to be modified and tailored for the industries. The results indicated that there are opportunities for a more effective and structured approach to energy management in industry. An initial reduction of 5% in energy consumption has been recorded and it is the company’s responsibility to ensure that their energy management becomes part of their corporate culture.

Abstract: Dioscorea hispida is a poisonous plant normally found in forest where scientific studies have shown that its tuber contains toxic poison and can be consumed after its poison is removed. Traditionally the tubers were placed in flowing river water for several days. In the harvesting aspect, an innovative hand tool were conceptually designed to replace the traditional hoe or “cangkul”. Using IMADA digital force gauge to measure the force required for pulling out the tuber and reverse engineering methods, an innovative hand tool were designed and developed. The results from experiments showed that the force required for harvesting the Dioscorea hispida tuber is found significant with its weight versus regression squared (R2) of 0.86. The information of optimum force required from field experiment is used to model the simulation and practicality in Computer Aided Design (CAD) environment system. The finite element on stress distribution on selected material of hand tool was simulated by uploading the material characteristic on simulation program embedded in Solidworks software. The end result of the simulation is based on visualization of analysis in Solidworks while producing the hand tool for designing and fabrication from material which is lighter and stronger.

Abstract: This paper reports on the design cost and scaling model of a small scale superconducting wind turbine generator, where the levelized cost of energy (COE) was calculated. The proposed design of the wind turbine is based on the vertical axis wind turbine (VAWT) type that drives the superconducting generator. VAWT was chosen due to its ability to operate under low wind speed. Wind turbine using superconducting generator was proposed since it is able to enhance magnetic flux within the stator of the generator and consequently improve the performance of the generator. Once the design has been accomplished, all the cost of parts and components must be accounted and contributes to the overall cost of generating electrical energy from the superconducting wind turbine generator. The cost elements include the initial capital cost (ICC), balance of station (BOS), operation and maintenance (O&M), levelized replacement cost (LRC) and annual energy production (AEP). The calculated levelized COE shows that the cost of generating electricity using superconducting wind turbine generator is lower than generating electricity from conventional sources.
