Abstract
The prevention of pollutants from textile wastewater is important to ensure a healthy life and sustainability of local development. This paper aims to determine the concentration of the physico-chemical water quality parameters in textile wastewater taken from a textile factory at Sri Sulong, Batu Pahat, Johor of Malaysia. The samples were directly brought to the laboratory for analysis, and the content of textile wastewater quality was characterized using physico-chemical analyses including temperature, pH, electrical conductivity (EC), turbidity, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), colour, alkalinity, total dissolved solids (TDS), and heavy metals (cadmium, copper, ferum, manganese, lead, and zinc). The results also indicated some of the parameters for final discharge textile wastewater could not be safely discharged because they did not comply with the standards of Standard B such as COD, BOD, colour, TSS, cadmium, and zinc. The results of this studies showed that the concentrations of COD, BOD, colour, TSS, cadmium, and zinc were between the range of 55 - 294 mg/L, 7.1 - 85 mg/L, 17 - 140 mg/L, 69 - 205 mg/L, 0.001 - 0.047 mg/L, and 0.488 - 2.220 mg/L respectively, higher than the values in Standard B. Textile wastewater is classified by pollution severity as strong wastewater. This study provides an understanding and assists in selecting suitable treatment for textile industrial wastewater prior to discharge to comply with the standard permissible of the environmental quality act.

Abstract
Assessing the potential hazard to the groundwater resource and surface runoff from solid waste disposal activities is considered necessary. This study focused on the effect of the leachate produced from the Piyungan landfill to both groundwater resources and surface runoff water quality. Groundwater samples were taken from point W1 (control) and W26, leachate samples were taken from LP1 (before treatment) and LP5 (after treatment), and drain samples were taken from L6 and L14, respectively. Heavy metals in these samples were analyzed using Inductively Coupled Plasma-Mass Spectrometer (ICP-MS). The results showed that leachate and drain samples had higher heavy metals content compared to groundwater samples. Leachate migration might happen in W26 since it located in the lower elevation of the landfill. For the leachate sample, the concentrations of Cr, Mn, Ni, As, and Se exceeded the allowable limit for raw water and leachate effluent. Deposition of heavy metals (Cr, Mn, Ni, As and Se) were also detected in W1 and W26 but still within the permissible limit. Continuous monitoring for heavy metals migration and the addition of leachate treatment processes in the landfill are suggested to avoid the occurrence of risky pollution to the surrounding area.

Published: June 2020

Abstract
Project success factors have become fundamental to project management practice in assuring successful projects. Yet, project failure has become common and a recurrent feature of infrastructure construction projects, not only in developing countries but also in most developed countries including Malaysia resulting in total abandonment of projects, prolonged project delay, cost overrun and client dissatisfaction. Researches on critical success factors impacting project results are important. Nevertheless, these researches are widely done in developed countries such as the USA and the UK under their culture orientation, while neglecting certain aspects, with limited evidence from developing countries such as Malaysia. This paper presents findings from a survey response from Malaysians who are project leaders, project management practitioners and project delivery team on their perception of project success factors. Selected literature review and survey questionnaire were used as data collection method for this study. Respondents’ national and organisational culture dimensions were analysed using Hofstede’s culture models and compared to the national and organisation culture dimensions of both the USA and the UK. The result of the analysis have suggested that that over and above age, and gender, individual perceptions of success factors varies with cultural differences. These findings have important implications for how companies can manage adaptation effectively to be able to achieve advantages in the various cultures where they operate while extending their main sources of advantage across borders, and in some cases even creating cultural diversity itself a supply of advantage.

Abstract
Libya is a developing country that suffers from an acute shortage of appropriate infrastructure and buildings. The reconstruction of Libya, especially in the aftermath of the 2011 uprising and the subsequent conflicts, requires applying effective strategies to minimize waste of, and efficiently manage, available resources. It is suggested that the adoption of Value Engineering (VE) may improve efficiency in decision-making. The aim of this paper is to present the process of using the Delphi Method to develop a research instrument suitable for assessing current VE practices as well as the factors that could influence the adoption of VE in the Libyan construction industry. The development of this research instrument has passed through three major refining phases, namely: (i) Back Translation, (ii) Pilot Study and (iii) Delphi Method. By the end of the Delphi study, 12 factors, derived from the literature, have been rated as relevant to the research instrument and considered as factors that could influence the adoption of VE in the Libyan construction industry. These factors are as follows; 1) awareness, 2) knowledge, 3) adhocracy culture, 4) market orientation, 5) transformational leadership style, 6) organizational learning, 7) product innovativeness, 8) process innovativeness, 9) business innovativeness, 10) information technology, 11) government regulations and 12) readiness to adopt VE. This paper may complement the existing body of knowledge on using the Delphi Method to enhance research instrument.

Abstract
Rapid advancement on digitalisation is changing the way buildings are planned, designed, built and managed nowadays. A collaborative computer-based environment known as Building Information Modelling (BIM) is one of the advancements introduced as a platform to boost up the efficiency of the construction industry. However, poorly designed, constructed and managed building or infrastructure contribute to environmental issues such as CO2 emissions and energy consumption. Thus, attachment of sustainability element in BIM not only increase the efficiency of the project but also can help to plan, design and construct in a more environmentally friendly way. A study on the overall energy use throughout the construction life cycle is needed to identify the most critical stages and to develop energy-reduction strategies via BIM. Thus, this paper provides an intensive review of BIM understanding, its energy analysis practices in the construction phase and existing building environmental assessment tools in BIM. To achieve this, an in-depth review was carried out focusing on the content analysis of a few journal articles related to BIM, energy analysis and sustainability assessment tool. Hence, this paper contributes by discussing the wide variety of building environmental assessment instruments and categorising existing tools to be used in the BIM.

Abstract
Increasing interests in the sustainable development of the Australian building sector has resulted in a surge of green buildings across the country. Nonetheless, limited studies have been done to compare green and non-green building tenants’ leasing motivators. To address this gap, this study aims to examine tenants’ leasing motivators toward tangible and symbolic aspects of office buildings. To this, a questionnaire survey was conducted, and the obtained responses were analysed using the Mann-Whitney U test, followed by an examination on their effect sizes. The results show that green buildings tenants put more emphasis on certain tangible aspects of office buildings such as building sustainability ratings, building quality and energy efficiency. Likewise, green building tenants’ higher emphasis on several symbolic aspects of office buildings, including their attractiveness to future employees, was found. The results inform policymakers and building owners that understanding tenants’ leasing motivators and establish targeted strategy is important to provide adequate office spaces.

Published: June 2020

Abstract
Road traffic accidents are the leading cause of death in most countries, and the eighth leading cause of death worldwide. In Malaysia, this situation is particularly alarming when data obtained from the Road Safety Department shows an increase in the number of road accidents over time. Zooming in to accidents involving employees working in organizations, a major concern emerged since a recent statistic from the Social Security Organization (SOCSO) of Malaysia shows that accidents reported to SOCSO increased from 61,552 cases in 2012 to 69,980 cases in 2017. Although covering both industrial and commuting accidents, SOCSO’s data on the latter for the construction sector recorded a total of 1,913 accidents in 2012 and continues to increase dramatically to 3,386 accidents in 2016, which among the highest within all industry sector. Defined as an accident while travelling back and forth to official business (from or to the workplace), previous data on commuting accidents for one of the nation’s crucial sector are further dampened the existing negative image of safety in construction. Furthermore, this issue has resulted in an increase in mortality, an extensive compensation claims, and losing valuable talent. Thus, following the hard-cold data presented by the paper, an initiative for a full-fledge research undertaking are in the pipeline. This to ensure a holistic solution for the problem in hand and ensuring improvement for safety and health of construction personnel particularly during commuting.

Abstract
Commercial and development-centered airports, or aerotropolis, develop together that results in “economies of speed.” There are two-hundred ninety-six (296) official airports in Indonesia, which is the most in ASEAN. PT Angkasa Pura I and PT Angkasa Pura II each manages thirteen (13) airports; the National ARMY operates fifty-three (53) airports, the Ministry of Transportation Airport Operator Unit manages one-hundred seventy-eight (178) airports, and the Local Government UPT oversees thirty-nine (39) airports. The research aims to find factors that influence regional government revenues and expenditures. The analysis begins with the coefficient of determination, a measure of the total variation in non- independent variables that could be explained by its relationship with the independent variable. Then, multiple linear regression analysis is used to determine the effect of airport performance variables on regional government revenues and expenditures (APBD) variables, using the multiple linear regression formula. The conclusion is that the input variables that have the most influence on regional government revenues and expenditures (APBD) are: (1) number of passenger departures, (2) number of passenger arrivals, (3) unloading baggage, and (4) baggage loading.

Published: June 2020

Abstract
Fibre reinforced polymer composites (FRPs) are being increasingly used in aerospace and automotive applications due to their high specific mechanical properties. The construction industry has also started taking advantage of the potential of FRPs for both structural and non-structural purposes. The result of this remarkable absorption of FRPs within the worldwide production market, has led to an immense increase of decommissioned thermoset-matrix components. Nowadays, the majority of the decommissioned FRP components are recovered energy-wise through incineration or simply discarded in landfills around the globe. Within the framework of this paper, we present a solution for the extension of the service life of decommissioned FRP components. Decommissioned electrical insulation FRP pipes were granulated and incorporated as fillers within both cementitious and polymer matrix composites. The effect of FRP granulates on the mechanical performance of cementitious and polymer matrix composites is examined to determine the maximum granulate-filler fraction that can be recycled without compromising the mechanical performance and manufacturing process.
Effect of The Dissolution Method With N, N-Dimethylformamide As A Solvent On The Electrical Properties Of Acrylonitrile Butadiene Styrene And Carbon Nanotube Composites
Authors: Pettit Estell Bryce M. , Gerhardt Rosario A. 
Published: June 2020

Abstract
The objective of this study is to create electrically conducting composite polymers using the dissolution method. Composites are made from Acrylonitrile Butadiene Styrene (ABS) as the matrix and Carbon Nanotubes (CNTs) as the filler. Composites were made using the dissolution method with N, N-Dimethylformamide (DMF). All the components were mixed then dried in a fume hood until they were formed into pellets in a compression molder. Compressed samples were optically and electrically tested. Results show that composites that were only dried in the fume hood have a bubbled structure and reach percolation around 1-5 phr. The bubbles were determined to be coming from water that got into the samples while they were drying in the fume hood. Composites were placed in a furnace at 100°C for 1 hour to take the water out of them. Results showed that furnace dried samples have a smooth surface and are more resistive than the bubbled composites. The bubbled samples were most likely less resistive than samples with a smooth surface because during the bubble formation the CNTs are being pushed closer together causing percolation to happen sooner.

Published: June 2020

Abstract
Al 7075 alloys are widely used in many mechanical parts because of their low density, light weight, and corrosion resistance. However, when mechanical parts are used in extreme environments such as high speed, high temperature, and high pressure, wear occurs more than allowable. To solve this problem, research and development of surface thin film deposition technology are increasing. Therefore, in this study, the wear characteristics were studied by depositing Ti films with excellent mechanical properties on Al 7075 according to the surface roughness by the deposition time. Results showed that 60’ sputtered specimens after polishing with alumina had the best wear resistance. In addition, the surface roughness of the base material and the deposition time of the thin film affected the wear resistance.

3:xEu
3+ were synthesized by the combustion method. The atomic concentration percentage of En doping was varied (x = 0%, 1%, 3%, 5% and 7at%). Structural and morphological properties were analyzed by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM) techniques, respectively. The XRD patterns of the pure (x = 0%) and Eu-doped (x=1at%) show the single Al2O3 corundum phase. For the highest Eu-doped concentrations of x = 3%, x = 5% and x = 7at%, the Al2O3:xEu samples, present a mixture of phases of corundum (Al2O3) and EuAlO3 (perovskite). SEM images show irregular grains with average sizes in the range of 0.1 - 78.8 μm. Photoluminescence (PL) analysis show that all Eu-doped Al2O3 samples exhibits intense red-emission. PL spectra show two main peaks at 615 nm (5D0°7F2) and 700 nm (5D0°7F4). The x = 3at% Eu-doped sample presents the highest intensity under 256 nm excitation. CIE coordinates were calculated from the PL spectra, values around x= 0.6 and y= 0.3 (red emission) were obtained from all samples. Due to its strong luminescence those Al2O3:xEu phosphors could be good candidates for components in solid state lighting.
