Nowadays, the expansions of train networks in Malaysia are dynamically developed. In the future, the railway networks are predicted to give the important role in the development of a sustainable transportation system in this country. Still, Malaysian is facing the challenge to improve the railway networks’ reliability especially that relates with the accessibility to the train stations. Electrified Train Services (ETS) is the first high speed intercity train system in Malaysia. Until the end of 2014, Ipoh is the last stop for Electrified Train Services (ETS) for train that bound for Kuala Lumpur –Ipoh. Due to the increment numbers of the ETS users, the problem of access and egress the station keep on exists. This study is focused on the 1000 ETS passengers’ in order to investigate their mode choice to access and egress the Ipoh Station. From the result, the majority of the users preferred to use private car for access (75.7%) and egress (79.6%) the train station. Taxi was the popular choice for public transportation compare to bus for both access (5.2%) and egress (12%). T-test analysis shows the significant different between the access and egress group in terms of travel distance from the origin location to the train station. This might be influenced by the factor of land use between Ipoh and Kuala Lumpur.

Phytoremediation are emerged technology among the environmentalist as the green technology and environmental friendly approach in the domestic, agricultural and industrial wastewater treatment. This method had shown their potential in reducing organics, solids, nutrients and trace metal concentration. Due to their potential in removing pollutant and improving the water quality, this technology had been used in industrial wastewater and effluent treatment such as aquacultures effluent, leachate and palm oil mill effluent (POME). Various species of aquatic plants such as water hyacinth and water lettuce had been utilized in the phytoremediation treatment and they demonstrate a pollutant removal with higher percentage in the wastewater like POME. Thus, this paper will review the phytoremediation potential of the constructed wetland (CW) treatment systems and their essential component in the POME treatment.

Biofiltration has quickly become an effective choice for treating odorous air streams as well as air emissions because of the improving reliability of these systems and also because of its reputation as a type of green technology with no hazardous residue and no utilization of chemicals. As odorous air flow through the system, the air compounds are oxidized by the microbes growing on the biofilter media. Four local biomass packing materials to be used as support media in biofiltration are analyzed and compared to evaluate their suitability according to physical and chemical characteristics. The characteristics of the packing material in biofilters is an important factor for the success in the biofiltration’s construction and operation. A set of six different parameters were selected to test the selected packing materials such as porosity, spesific density, surface area, water holding capacity, moisture content, pH and purchase cost. Since biofiltration success generally depends on a combination of several parameters either from the system or the materials choosen, a procedure was defined to compare packing materials suitability under common situations in biofiltration. The results indicate that, out of the packing materials studied, palm kernel shell and wood chip were ranked on top of several parameter rankings and showed as a significantly better packing materials when parameters were combined.

Connections are joints or nodes which are used to joint elements of a structure at a point such that forces can be transferred between them safely. Tapered steel section with perforation is normally used in construction industry due to light weight. The connection modelled in this research is extended end plate welded with tapered beam steel section with perforation and then bolted to UKC front flange of column. This connection was modelled by using Finite Element software, LUSAS to determine the moment rotation curve, deformed shape and maximum displacement of the connection. The results were compared between perforated and non-perforated sections. The dimension of the model sizes are 460 x 200 x 10 mm thickness of endplate, 457 x 191 x82 UKB provided with 0.4h opening size and tapered ratio of 0.3 and 254 x 254 x 73 UKC. The Finite Element models were varied in terms of the distance from first opening to column’s face and spacing between openings. The parameters of the openings affect the connection behaviour in a number of ways. It was found that when the distance between first opening and column face become longer, the effect of openings is eliminated. Moreover, tapered steel beam section with perforation has less moment resistance value than tapered steel beam section without perforation as much as 4.34% to 9.70%

Triangular web profile (TriWP) steel section with various combinations of perforation shapes, sizes and layouts of perforation are investigated under shear loading condition. The aim of this study is to determine the structural efficiency based on the ratio of buckling load, Pb to the self-weight of the model. For this purpose, the specimen with three different perforation size between 0.4D to 0.6D, five perforation shapes i.e. circle, square, hexagon, diamond and octagon and three different layouts of perforation, which are Layout 1, Layout 2 and Layout 3 are analyzedby using LUSAS software. It involves two stages of analysis which are Stage 1 and Stage 2. In Stage 1, the most efficient perforation shape, size and layout of perforation is determined based on the highest structural efficiency value. From the result obtained, the TriWP with perforation of diamond in shape and 0.4D in size arranged in Layout 3 shows the highest structural efficiency value i.e. 204.75 produced from the highest buckling load. It shows the lowest percentage difference of efficiency compared to that of TriWP without perforation i.e. 16.39%. It leads to the most efficient perforation shape, size and layout. Then this type of model is analyzed for different section properties and span length to observe the effect performance and its structural behavior under Stage 2. It observed that, shear buckling capacity increase proportional to the web thickness. Meanwhile, when the span length is increase from1 m to 5 m, the shear buckling capacity reduce.

Housing is one of the basic needs for human being. In Malaysia, there are most low cost and low medium cost houses being constructed due to high demand which in line with the fourth strategic objective outlined in the 10th Malaysia plan. The total number of population in Malaysia has increased by 0.17% from 17,563,420 in year 1991 to 27,565,821 in year 2010. Owing to this substantial increased, most of the low-income group cannot afford to own a house. The purpose of this paper is to identify keyparameters of low-medium cost housing demand in Malaysia through questionnaire survey with local experts within the construction industry. Data acquired from the questionnaire survey is analysed using Mean Rank adopted from the Statically Package for Social Science (SPSS). Also the parameters identified are analysed using frequency analysis to determine the frequency and ranking. As a result, eight parameters for medium cost housing demand have been identified rom this study, namely population, economy, household income, ability of buyers, housing prices, politics, land price, and experts from industries. Ranking from experts has indicated that household income as the most prioritised parameter for lost medium cost housing, which are then subsequently followed by population, economy, house price, land price, ability of buyers, experts from industries and politics respectively.

Despite the many road safety initiatives introduced in the state of Penang in Malaysia, the results have not been encouraging. This is especially critical when the expectation of the Decade of Action for Road Safety is to halve all road safety performance by the year 2020. The conventional intervention-based approach has been proven to have limited success and potential for the expected more drastic results. A critical analysis on the matter suggested that the passion for road safety results had dwindled as many players approach them as only processes that may not necessarily provide us with aspired road safety outcomes. This paper discusses the development of Road Safety Strategic Plan for Penang State through the outcome based approach. This pioneering effort begins by defining the appropriate goals for 2020 and followed by describing four principal strategic pillars. The pillars are changing attitude, forgiving roads, safer for motorcycles and enabling data and information. Each pillar has its own targeted outcomes, making a total of 28 outcomes identified. The appropriate activities and interventions in order to achieve the outcome were also recommended. The remainder of the paper also discusses the implementation plan suggested to the authorities and decision makers and other players in order to achieve the road safety targeted outcomes. Early results will also be highlighted in the paper.

This paper presents the study on the behaviour of the beam to column connection by using flush endplate connection for I-beam steel section with perforation. Moment rotation and failure pattern of flush end plate connection for perforated section were studied. The model was modelled by using LUSAS software and then analysed with nonlinear finite element analysis. Nineteen models were generated for flush end plate connection with perforated beam section consisting of variable parameters such as opening size, distance between the first opening and column face, and spacing between the openings. The moment resistance and rotational stiffness of the connection are found to be reduced by the presence of the openings. The geometric parameter of the openings affected the behaviour of the connections. It is found that the larger the opening size, the lower the strength and rigidity of the connection. Furthermore, it is found that the presence of openings causes increment in the deflection of the beam. However, some perforated sections with optimum geometric parameters for openings have higher strength to weight and rigidity to weight ratio than normal section without perforation. In this study, the most effective geometric parameter for openings are found to be size of 0.65h, distance between the first opening and column face of 800mm and spacing between openings of 1.3h (h is the depth of the beam web).

Rapid expansion in major towns in Malaysia results in the construction of new drainage system mainly open monsoon or storm drains to cater the increase in surface runoff. This research are to study the suitability of selected sites to implement InSmarts and propose at selected sites based on the optimum results. InSmarts is a floatable trapper that was being synchronized with the effective and bettercommunication tools. This product mainly consists of a fibre reinforced plastic tube that acts as floatable rubbish trapper. Acoustic Doppler Current Profiler (ADCP) was used to get water velocity and river profile at sites. The data was acquired at three different points along the river at each sites to know the best position to implement InSmarts. These tests were done to find out the attributes of different rubbish materials and weights in the flowy medium such as river or drainage. From the test that has been done, the optimum condition to install at sites are the velocities of the river must be around 0.1 m/s to 0.6 m/s and the trapper must be set up at 45° angle to accumulate the trash at one side of the trapper.
