Exploration of Building Information Modelling (BIM) Application: An Understanding Among Quantity Surveyor in Malaysia

This study begins with a broad literature review to understand the Building Information Modelling (BIM) concept. Quantity Surveyors star as an influential role as qualified, trained, and proficient in dealing with glitches relating to construction expenditure, supervision, and consultation in the construction industry. When the task is getting crucial, an assistant from technology may help faster and smoother the process and task. This study aims to investigate an understanding of the application of BIM among Quantity Surveyor in Malaysia. According to the Board of Quantity Surveyors, Malaysia's official website, 101 registered Quantity Surveying Consultant firms were in 2018. This study targeted 1000 persons from different firms and expected to respond from at least 278 persons due to time constraints. The other criteria of the respondents include years of experience in the industry. Quantity Surveying Consultant firms would be the most suitable people to answer a questionnaire survey for this study. The registered Quantity Surveying Consultant firms are very well proficient in the quantity surveying practice and services. Therefore, by choosing Quantity Surveying Consultant firms to be the respondent may help in getting the most consistent answer and higher accuracy of the exploration of Quantity Surveyors productivity by adopting the Building Information Modelling (BIM) concept in Quantity Surveyor, which will further enhance the awareness of benefits of BIM to the Quantity Surveyor profession itself.

A Case Study: Implementation of Automated Guided Vehicle Replacing Trollies Transportation in Manufacturing Industry to reduce Motion Waste in Lean Manufacturing practicing factory

This research introduces and demonstrates the procedures and method used to eliminate waste of motion to achieve lean manufacturing which is the starting for Industrial Revolution 4.0. This was conducted in a private manufacturing factory that assembles printed circuit board (PCB). The research done provides an advantage by developing an efficient and effective way to carry out the transportation of PCB magazine trolley. The data collected and results obtained proved the benefits of the utilization of automated guided vehicle. In contrast, result attained for time reduction of transportation of PCB magazine trollies was in the range of 3.39% to 8.08%. Moreover, autonomous guided vehicles also verified the capability to eliminate the occurrence of human error and non-added value activities. In conclusion, the research carried showed a successful method towards optimization of the production in the selected PCB assembly manufacturing company.

Crowd Dispersal in Staircase Design for Multi-Storey Building

Staircase evacuation has always been a popular topic as today’s buildings are mostly dependent on the staircase for vertical transportation. This paper discussed the effect of open staircase position and width towards evacuation duration and distance. To simulate a real emergency situation, an experimental study needed to be conducted by using pathfinder software. Results show that increasing escape route width improves evacuation duration but the distance is much influence based on the positioning of the staircase in the building. The different staircase scenario has a significant influence on crowd dispersal. Future study can focus on various speed of the occupant to see how it will influence the crowd dispersal in a multi-storey building.

Design of Reconfigurable Stacked Patch Microstrip Antenna (RSPMA) at 1.8 GHz and 2.3 GHz

This paper presents a Reconfigurable Stacked Patch Microstrip Antenna (RSPMA) uses a combination of aperture coupled technique and stacked patch technology for reducing feigned radiation patterns. This RSPMA consists of three FR-4 substrate layers with 4.7 mm thickness each and 3 mm thick of an air-filled substrate between stacked patches and the ground plane. The top patches are rectangular shaped with a T-shaped hole at the center and the bottom patches are T-shaped, both etched on top of substrate 1 and substrate 2 respectively act as a radiating element. Two H-shape designs of aperture slots of different sizes on the ground plane are positioned at the center of the ground plane with reference to the top patches and bottom patches. A copper strip is used as an ideal RF switch is implemented at the feed line network for the ON and OFF mode. Thus, by adjusting the switch mode, the resonance frequencies can be varied, thus frequency reconfigurable is achieved. The activation of the selected aperture slots will produce waves and radiates the signal to the radiating layers of the patch antenna. Hence, two different frequencies, either at 1.8 GHz or 2.3 GHz were achieved through the RSPMA with the gain of 3.691 dB and 2.291 dB, respectively. The antenna designed was simulated using CST Microwave Studio at an operating frequency of 1 GHz to 2.7 GHz. The RSPMA is said to be potentially beneficial to the wireless communication system.

Exploratory Factor Analysis (EFA) of Website Design Factor for Airlines ETicketing System in Malaysia

The main motivation of this study was to investigate the level of satisfaction towards online purchasing among people those had experience using airlines e-ticketing websites in Malaysia. This paper highlights the detail of exploratory Factor Analysis (EFA) procedure that tested on web design towards airlines e-ticketing website in Malaysia. The result was written based on findings of a survey conducted among Malaysian and non-Malaysian customer. The study was further down tested into website design factor. The samples of this study were 510 respondents from all over Malaysia area. The study obtained samples by using random sampling method. The finding based on the EFA result of the survey.
