A supplier selection strategy within the Malaysian telecommunications industry

The telecommunication industry in Malaysia has grown rapidly over the last 15 years, with effective supply chain management becoming increasing important within the sector. A multitude of providers and part owned Malaysian government companies, vendors and suppliers are involved in generating and creating value-adding products and services within this sector (across wireless, wireline, broadband business and consumer lines of business). This paper describes key challenges facing a major telecoms service provider in Malaysia with regards to drivers involved in the overall procurement and supplier selection with regards to components of performance management, decision-making, selection techniques, quality and cost management, procurement policy and procurement ethics. This paper further focuses on defining and detailing research currently being undertaken to develop a framework for identifying supplier selection drivers that are inherent within the sector and suggests a research approach to investigate and develop strategies for supplier selection for the telecommunications industry in Malaysia

Bow-Tie Microstrip Antenna Design

In this paper, the bow-tie microstrip antennas have been designed with two different angles of 40° and 80°. An investigaton on the effect of the angle to the return loss and radiation patterns had been carried out. The impedance matching network with the niicrostrip transmission line feeding was used in this study. Simulation and measurement results for the return loss and radiation patterns were presented

Non-excusable delays in construction

Existing literature and research findings indicated that delays are common amongst construction projects in many countries across the globe. Delays can be caused by one or more of the following: the client (excusable with compensation); force majeur or third party (excusable delays without compensation); or the contractors (non-excusable delays or contractor-responsible delays). Previous studies cited that approximately 50% of these delays can be classified as non-excusable delays. The root-causes (or factors) that cause non-excusable delays identified in these studies however, are given no detailed attention. Improving and constantly monitoring the factors causing non-excusable delays can help to determine and improve contractor's performance. This research explores issues related to the factors causing non-excusable delays. [Continues.

Characterization of ash derived from combustion of paper mill waste sludge: Comparison with municipal solid waste incinerator ash

Fly ash derived from incineration of Malaysian paper mill waste sludge (PMWS) was physically and chemically characterized in order to determine its potential toxicity as well as its application as cement replacement material. The results were compared with results obtained from similar characterization on Malaysian municipal solid waste incineration (MSWI) bottom ash. Principal analyses conducted include particle size distribution, elemental analysis, toxicity characteristic leaching procedure (TCLP) as well as thermogravimetric, x-ray diffractometry and FTIR analyses. TCLP result indicated that both the PMWS and MSWI ashes should not be classified as hazardous wastes in terms of heavy metal leachability, since leachable copper, cadmium, lead and nickel concentrations were detected below the stipulated leachability limits. Both ashes could be reused as cement replacement materials since both contained SiO2 which is one of the main building components in cement and concrete utilizations. Nonetheless, PMWS ash could be more suitable as a cement replacement material as compared to MSWI ash, as the former had significantly smaller particle size distribution and lower organic content

Reconstruction of virtual environment using CAD-VR approach

Virtual environment should be able to replicate real environment as realistic as possible. This paper proposes a design framework for constructing virtual environments using Computer-Aided Design (CAD) and Virtual Reality (VR) packages, or in short, CAD-VR approach. This paper discusses the technical issues involved based on the experience in developing two prototype models of the Universiti Utara Malaysia Sports Complex and Sultanah Bahiyah Library. The benchmark of the development is the compatibility of the three dimensional (3D) CAD models with VR packages. The CAD modelling issues that have been encountered throughout the development stages are also discussed for future guidelines

Developing the Immunology Book for Animal and Human Physiology Subject

The objective of the study was to develop an immunology book for Animal and Human Physiology subject. This book was developed based on the Thiagarajan development model which was modified of: Define, Design, Develop, dan Disseminate (4D). The data expert validation instrument was questionnaire using Likert scales, comments, and recommendation sheets. Expert appraisal was done by material expert and media and design learning expert. The developmental testing was conducted using questionnaire to test the readibility. The expert validation was conducted by material expert as well as design and media learning expert validator; meanwhile, the field test was done to measure the readability. The validity test results were: the material expert state that the material is valid (97.14%), as well as the design and learning media expert (84.88%) and field test by students (88.17%)

Influence of Halal certification on customers’ purchase intention

The purpose of this study isto investigate the relationship between HALAL awareness, marketing and religiosity that are postulated to influence customers’ intention to purchase HALAL certified consumer products. Customers’ who visited SABASUN Hypermarket Sdn. Bhd. in Kuala Terengganu were selected as respondents. Questionnaires were used as the research instrument. The findings revealed there are positive relationship between the HALAL awareness and religiosity toward customers’ intention to purchase HALAL certified consumer products. The results also demonstrated that religiosity is the most influential factors in motivating customers’ to purchase HALAL certified products. For future study should consider demographic background as a moderating factor the can regulate the effect on factors influencing customers’ intention to purchase Halal certified consumer products.Keywords: religiosity; halal certified; halal; customer’s intentio

Evaluation of Hybrid Membrane Bioreactor (MBR) For Palm Oil Mill Effluent (POME) Treatment

The pollution load of palm oil mill effluent (POME) is in the range of 50,000 mg COD/L. With more than 500 palm oil mills, Malaysia produces some 13.9 million tonnes of crude palm oil annually and generates around 35 x 106 m3 POME. Typically, raw POME is difficult to degrade because it contains significant amounts of oil (tryacylglycerols) and degradative products such as di-and monoacylglycerols and fatty acids. The fatty acids composition (C12 – C20) of each of this fraction are different from one another and contribute to the high value of pollution load in POME. Thus POME has to be treated, usually in a series of anaerobic and aerobic treatment steps, for the organic matter to be degraded before the effluent is allowed to be discharged into public waterways. The objective of this study was to observe the performance of a hybrid membrane bioreactor (MBR) for POME. The raw POME was introduced into sequencing processes of anaerobic, anoxic and aerobic in order to achieve biological nutrient removal and the membrane modules were submerged into the aerobic zone. The critical flux of MBR using the flux-step method based on transmembrane pressure (TMP) was conducted as well as flux and permeability studies for assessing fouling in a membrane bioreactor operating at constant flux. The reactor was operated at a mixed liquor suspended solid (MLSS) concentration of 4000 to 8000 mg/l. The removal efficiency of COD, SS, TN and TP achieved were 94%, 98%, 83% and 64% respectively. The hybrid MBR was found to be able to degrade POME significantly and high quality effluent could be reused for various other applications.Keywords
