As the demand for green technology is rising rapidly worldwide, it is important that Malaysian researchers take advantage of Malaysia’s windy climates and areas to initiate more power generation projects using wind. The main objectives of this study are to build a functional wind turbine and to compare the performance of two types of design for wind turbine under different speeds and behaviours of the wind. A three-blade horizontal axis wind turbine (HAWT) and a Darrieus-type vertical axis wind turbine (VAWT) have been designed with CATIA software and constructed using a 3D-printing method. Both wind turbines have undergone series of tests before the voltage and current output from the wind turbines are collected. The result of the test is used to compare the performance of both wind turbines that will imply which design has the best efficiency and performance for Malaysia’s tropical climate. While HAWT can generate higher voltage (up to 8.99 V at one point), it decreases back to 0 V when the wind angle changes. VAWT, however, can generate lower voltage (1.4 V) but changes in the wind angle does not affect its voltage output at all. The analysis has proven that VAWT is significantly more efficient to be built and utilized for Malaysia’s tropical and windy climates. This is also an initiative project to gauge the possibility of building wind turbines, which could be built on the extensive and windy areas surrounding Malaysian airports.

Lean tools and applications have been adopted globally by many companies and industries such as automotive, aerospace, healthcare, pharmaceutical, shipbuilding, public services, project management and several others. The most basic of lean tools can be distinguished by the following: Value Stream Mapping (VSM), 5S and Kaizen, and many have agreed that these are the best selections in the initial approach of lean system and these techniques are part of the Y Management System (YMS) initiatives. This research is intended to make VSM as the primary working culture, which has been proven suitable to the servicing companies that conduct Maintenance, Repair and Overhaul (MRO) activities. With full cooperation from Company X Sdn. Bhd., researchers were able to review and later harmonize the implementation flow of VSM with the intentions to increase their personnel’s production rate significantly. The rudder repair project involving the maintenance of Royal Military Airforce’s Skyhawk aircraft has been given the opportunity to be experimented with VSM. After the analysis of all 53 personnel involved, it can be concluded that the lean implementation has considerably improved their individual performances, organizational behaviours, future work mapping and personal/team workstations.

Following a recently-submitted review on a few human factor identification models (interpretations of Professor Edwards’ SHELL Model, Boeing’s Maintenance Error Decision Aid (MEDA), Professor Reason’s Swiss Cheese Model, and Dupont’s Dirty Dozen), researchers have unanimously agreed on choosing the Dirty Dozen model for this quantitative study before its official implementation in hangars and workshops at Universiti Kuala Lumpur – Malaysian Institute of Aviation Technology (UniKL MIAT). This study measures the levels of awareness and effectiveness of UniKL MIAT’s current human factor safety practices. A specifically-tailored, comprehensive, Dirty Dozen checklist is produced and distributed as survey questionnaire to 120 UniKL MIAT’s students. Data from all 48 questions related to all 12 domains of Dirty Dozen are analyzed. The results shows that out of all 12 domains, six (Lack of communication, Lack of teamwork, Norm, Pressure, Lack of attention, Stress) are marked with “Agreed” and the other half (Complacency, Lack of knowledge, Lack of resources, Distraction, Lack of authority, Exhaustion) are marked as “Not Sure” in terms of awareness and effectiveness of their current human factor’s safety practices. These results will be reviewed by the top management of the university to take preventive actions and improvements for future human factor safety implementations. As Dirty Dozen is known to be the simplest technique to measure human error, it is significantly appropriate to be applied as this experiment’s variable, especially for students who are still studying and have no industrial working experiences.

The purpose of this study is to determine the factors that influenced competitive pricing for airlines in Malaysia. A particular route, Kuala Lumpur to Singapore has been selected as the case study whilst observing a comparison of competitive pricing between full service and low cost carriers. This research was derived in response of World’s Busiest International Air Routes report from OAG Aviation Worldwide that shows more than 30,000 flights frequency on average in both directions for international route Kuala Lumpur to Singapore on an annual basis. This study will try to explore the influence in competitive pricing between forecast on demand and product quality. A framework model has been proposed to determine the factors on competitive airlines pricing in Malaysia. The outcome of this study is to assist airlines to develop an effective approach for competitive pricing for passengers to choose their desired air carrier for short haul flight sectors.

: The purpose of this study is to examine how problem-based learning (PBL) is adapted in an online teaching medium using Microsoft Teams and then utilized in Aviation English classrooms at a Malaysian aviation-based technical institution with the purpose of testing for any discernible effect. Using Microsoft Teams, lecturers guided ﬁnal-year Aircraft Maintenance undergraduates into self-directed study and peer instruction for ﬁve consecutive weeks. A study was performed to determine the inﬂuence of online PBL instruction on learners’ exam results. The paired sign test was used to analyze the non-normal data in SPSS—the mixed results showed that additional studies should be carried out for additional areas of study/curricula when pursuing PBL-Institute prestige in order to enhance the online PBL implementation processes and choose the most appropriate online PBL framework for each area of study.

This paper is aimed to determine the strengths and weaknesses of Kuala Lumpur International Airport (KUL) against its competitors in Southeast Asia countries. Due to the geographical and market relevance issues, several airport hubs around KUL are chosen for comparison: Changi International Airport (SIN), Suvarnabhumi International Airport (BKK) and Soekarno-Hatta International Airport (CGK). Strengths, weaknesses, opportunities and threats (SWOT) analysis is used to evaluate the comparative situation between the airports in relation to changing industry and market environment. The study discovers some competitive edges for KUL. Nonetheless, the airport still has to be improved to face future challenges and it is under imminent threat of new aircraft technology.
