8:00 Usability Metrics for a Web-based Test Blueprint System
Amando P. Singun, Jr. (Higher College of Technology, Muscat, Oman)
Vast range of educational systems and technologies seamlessly support or facilitate the educational setting which necessitate an increased attention on their usability. Improving the usability of such systems and technologies can increase productivity while the use of available organizational resources could be maximized, at the pleasure of the stakeholders of the institution. The ISO 92141-11 Usability Framework is used in this study, focusing on the use of usability metrics to measure the usability goals of the web-based test blueprint system in terms of its effectiveness and efficiency as well as user's satisfaction. Effectiveness is measured through completion rates and number of errors whereas efficiency is measured based on the time-based efficiency or overall relative efficiency. Post-task users' satisfaction and test-level users' satisfaction are measured through standardized survey instruments such as Single Ease Question (SEQ) and System Usability Scale (SUS) Questionnaire respectively. The usability goals are dependent on its context-of-use ranging from the user characteristics, embedded technologies, required tasks, and environment. The Results of the usability metrics are influenced by the context-of-use or circumstances surrounding the system. The web-based test blueprint system has a SEQ score of 5.55 and SUS score of 90.00 which imply that the web-based system is highly-effective and highly-efficient which highly satisfies the users. The SUS mean value is interpreted as a promoter score because users tend to promote the system to others because of its high acceptability level and remarkable ease-of-use.

Khalizani Khalid and Sam Eldakak (Abu Dhabi University, United Arab Emirates); Hajah Fadilah Hj Puteh (Universiti Teknologi MARA, Malaysia)
The purpose of this study is to measure the relationship between trainee's self-efficacy, OJT and classroom training on training effectiveness in the Malaysian construction industry. From 248 surveys that have been randomly distributed to multiple department's employees working in the construction companies; 73% response rate was collected (n = 180). The analyses of the internal consistencies of the scales yielded satisfactory and all studied variables were positively and significantly correlated with value between 0.218 and 0.596; and there is no evidence of multicollinearity. The first rregression analysis has found that self-efficacy (R2 = 0.114; β = 0.337, p < 0.05), OJT (R2 = 0.198; β = 0.444, p < 0.05), and classroom training (R2 = 0.351; β = 0.596, p < 0.05). The multiple regression model produced self-efficacy (β = 0.192, p < 0.05), OJT (β = 0.192, p < 0.05), and classroom training (β = 0.486, p < 0.05) on training effectiveness using with variance of 42.7 percent. In both models, classroom training has shown to have better causal-relation in comparison to other factors in both analyses. The results of the current study have consistent with prior studies that found self-efficacy, OJT, classroom training were positively and significantly affect training effectiveness. The significant of training effectiveness on organization was discussed.

9:00 A Remark of Diversification Benefit From Financialized Commodity Portfolios
Rangga Handika (Abu Dhabi University & Universitas Indonesia, United Arab Emirates); Mahjus Ekananda (University of Indonesia, Indonesia)
We find a remark of diversification benefit in the financialized commodity markets. Using eight financialized commodities at different data frequencies (daily, weekly and monthly) and different confidence levels to construct seven equally weighted portfolios, we find that on average commodities portfolios tend to have less accurate VaR. We conclude that even though portfolios have diversification benefit of risk reduction, there is a remark by obtaining a less accurate VaR.

The increasingly development of Islamic finance in Malaysia will give effect on financial decision making. Most of the banking institutions are offering Islamic financial products to consumers. Therefore it is very crucial to access the peoples' level of Islamic financial literacy in order to give suggestion in guiding them to make decision. The purpose of this study is to assess the level of Islamic financial literacy among consumers in rural area. The respondents are among the consumers in Bandar Tun Razak (Jengka), Pahang. It also aims to examine level of components in Islamic financial literacy which are knowledge, investment and financing. Descriptive analysis was used to analyze response from a sample of 231 respondents. The result of this study shows that the level of Islamic financial literacy among respondents in terms of knowledge, investment and financing are at moderate to low level. It is important for the community, government and financial advisor to increase the level of Islamic financial literacy by implementing various Islamic financial education programs. Lastly, this study is considered as one of the studies that have contributed to the literature by developing understanding of Islamic financial literacy.

The performance of cryptocurrency under Efficient Market Hypothesis is important as it provides understanding to the behavior of its price movement. It is important to determine the cryptocurrency behavior under efficient market theory to ensure that no speculators or investors are able to take advantage as well as to guarantee fair competition and promising growth in the market. This study used Bitcoin and Litecoin time series data. The study analyzed the presence of heteroscedasticity, serial correlation and tested for structural break with Bai-Perron test. The sample data is model into GARCH (1, 1) unit root model with structural break. The market efficiency is analyzed through the performance of the model in unit root test namely the Augmented Dickey-Fuller, DF-GLS, Phillips-Perron, KPSS, ERS and Ng-Perron. The analysis show that the market efficiency hypothesis in Bitcoin and Litecoin market is inconsistent with weak form of efficiency as the unit root test show Bitcoin model is stationary. This is consistent with the cryptocurrency behavior as it is subjected to speculative bubble. Cryptocurrency has no intrinsic value and it depends on the speculation power. Thus, investors might overvalue or undervalue the cryptocurrency which in turn further effect the market price

Mazurina Mohd Ali (Universiti Teknologi MARA Selangor, Malaysia); Nor'Azam Mastuki (Unversiti Teknologi MARA, Malaysia); Syarifah Saffa' Najwa Tuan Besar (Universiti Teknologi MARA Selangor, Malaysia)
The purpose of this study is to examine whether the market perceives financial restatements as an important factor when it determines the value of the company. The sample comprises of 250 public listed companies on the Main Board or the Second Board of Bursa Malaysia for the years between 2005 and 2015. A multivariate regression analysis is used by employing the Ohlson's (1995) valuation model, and it is based on the methodology developed by Davis-Friday, Eng and Liu (2006). The study finds no significant relationship between financial restatement and firm value. However, the results highlight that the equity book value and earnings reported in the financial statement is value-relevant for investors in assessing Malaysian firm's value.

Spinal cord injury (SCI) is a tragic event often leading to permanent physical disabilities with a negative impact on the quality of life of those affected. For example, SCI causes some impairments that lead to secondary complications such as pressure ulcers, obesity, osteoporosis, musculoskeletal deformities and cardiorespiratory problems among others. Individuals with SCI are susceptible to high morbidity and mortality rate due to lack of physical activity. Evidence suggests that coronary heart disease is a leading cause of mortality in these individuals. Improvement in functional capacity, engagement in physical activity and exercise have been used to promote cardiovascular function. Many researchers have suggested a hybrid cycling exercise as the most beneficial intervention as it combines both the arm and lower limb cycle to maximize physical activities for greater cardiovascular fitness. However, this mode of exercise is still uncommon in the routine clinical practice, and little is know about such exercise modality in SCI survivors. Thus, this review is to discuss the potential health benefits of physical activities and exercise among individual with SCI as well as the effects of hybrid cycle exercise on cardiovascular and musculoskeletal systems. The findings from this review revealed that further clinical studies are needed to understand the specific effects of hybrid cycling exercise in to prevent retrogression of cardiovascular function and fitness for individuals with SCI.

Numbers of diabetic patients with Diabetic Peripheral Neuropathy (DPN) and stroke are increasing worldwide. Diabetes Mellitus can give rise to macrovascular and microvascular complications and among which is stroke and peripheral neuropathy respectively. Literatures have revealed that DPN and stroke populations exhibited significant deterioration of postural control and gait performance, and reported worsening in the presence of cognitive impairment. Walking with balance and gait dysfunction among DPN with additional stroke event may create destabilizing effects dan fall. To date, there is no comprehensive study of postural control and gait performance among DPN with additional stroke has been published. Therefore, the aim of this paper is to explore further on the postural control and gait performance following dual disability of DPN and stroke.

Currently, there are few textural measures being used to characterize the textual memorization of brain structures. Fractal Analysis (FA) application in medical field has been used to measure the occurrence of changes in the brain complexity for some diseased and normal aging brain. Within FA, there is Fractal Dimension (FD), which is an index of structural complexity. FD methods were classified into three major categories which are box-counting method, variance method and spectral method. Here in this study we used box-counting method to measure our FD due to its directness and automatic computability capabilities. We evaluated the impact of different thresholding techniques when quantifying the FD. We applied three different thresholding techniques on our brain MRI images: Otsu's method, midpoint method, and hysteresis method. A total of 27 subjects (14 males and 13 females) aged ranging between 21-25 years old were voluntarily participated. The process of thresholding the images and computation of the FD values were done under MATLAB. There was a statistically significant difference between groups of thresholding techniques as determined by Friedman test with χ2(2)=48.667 and p-value was less than 0.001. Post Hoc Wilcoxon-Signed Ranked test with Bonferroni correction done where the p-value was set to 0.017. All three group pairs (midpoint vs Otsu's, midpoint vs hysteresis and hysteresis vs Otsu's) were statistically significant different with p-value less than 0.001. Pearson's correlation showed moderate correlation (r=0.446, p-value = 0.02) between hysteresis and Otsu's. Spearman correlation showed weak correlation which is not significant (r=0.256, p=0.198) for midpoint vs Otsu's and (r=0.252, p=0.204) for midpoint vs hysteresis. In conclusion, different thresholding techniques do have impact on FD values, but with moderate correlation between them.

Sook Fern Yeo (Multimedia University, Malaysia); Cheng Ling Tan and Yen Nee Goh (Universiti Sains Malaysia, Malaysia)
This study emphasises on examining the relationship between service quality and satisfactions towards patients' repatronage intention for obstetrics services in private hospitals in Malaysia. The conceptual framework is developed from the combination of the literature related to service quality to repatronage intention via the mediating effect of patients' satisfaction. The service quality dimensions consist of doctor'scare, nursing care and medical treatment whereby they are group and known as technical quality. Furthermore, the technical quality of the Gronroo's model is suitable for measuring obstetric services. This study will generate the understanding on which factors will influence patient repatronage intention for the obstetrics service in private hospitals in Malaysia.

Cox Proportional Hazard model is the most popular technique to analysis the effects of covariates on survival time, in most medical studies, non-proportional hazards are very common situation in the presence of one or more covariates that vary over time. Then, other models such as non-PH models may offer great advantages over Cox PH model in modeling those covariates under non-PH situations. The aim of this study was to compare the Cox PH model with non-PH model as well as to evaluate the prognostic factors that affect survival time among RHD patients. The data obtained from 721 patients with Rheumatic Heart disease between 1st January 1992 until 31st December 2011. Both Stratified Cox Proportional Hazard with and without interaction of non-PH covariate models were performed as non-PH models. By using AIC and deviance, the efficiency of the model performance was obtained via Cox PH, and non-PH models were compared and the most suitable model was determined. Based on deviance and AIC, the Stratified Cox PH model without interaction of hospital stay is the best model. Five statistically significant prognostic factors that contribute to the risk of death among RHD patients were identified, which are diagnosed as emergency status, mitral valve repair alone, Hypertension , Post-operation status and longer Coronary Pulmonary Bypass. In the multiple covariates analysis, all non-PH models fit better than Cox PH model with respect to the lowest for both deviance and AIC values. This is important as an alternative approach that can cope with the non-PH situation.

Lignocellulose is the most abundant renewable resource available from plants in this case from coconut husk. Bioconversion products of lignocelluloses have biomedical significance. This study was to identify previously isolated lignocellulosic bacteria strains which have the ability to degrade lignin and cellulose. The techniques used in this study confirms bacteria identity by sequence analyses of 16s rRNA, Gram staining, motility test, crystal formation test and penicillin sensitivity test (10µg of Penicillin G - P-10). Gram staining was performed on six bacteria strains to distinguish between Gram negative and Gram positive cells. Extraction of genomic DNA for 16s rRNA sequence analyses were also conducted on the six bacteria strains to differentiate between species. Four out of six bacteria were identified as Bacillus thuringiensis (T10), Enterobacter aerogenes (T19), Bacillus pumilus (T22), and Bacillus vireti (T24) using sequence analysis of 16s rRNA compared to NCBI database. Two bacteria strains, C19 and C37 belong to the Genus Bacillus which had more than one possible species results which were distinguished by using biochemical test. Four bacteria strains were Gram positive (T10, T22, C19 and C37) and two Gram negative (T19 and T24). Motility test was negative for C19 and positive in C37 isolates. Isolate C19 had a diameter of 32 mm which showed susceptibility to Penicillin; whereas for isolate C37 had a diameter of 19 mm which showed resistance to Penicillin. Isolate C37 was confirmed as B. thuringiensis after four days incubation by using crystal formation test. This study suggests that the isolates T10, T19, T22, T24, C19, and C37 were identified as B. thuringiensis, E. aerogenes, B. pumilus, B. vireti, B. anthracis, and B. thuringiensis respectively. Future studies using metabolic engineering techniques can optimise their lignocellulose degradation potential in suitable vectors.

Evana Kamarudin (University Technology MARA, Malaysia); Mohd Khairul Amran Mohammad (Universiti Teknologi MARA, Malaysia); Rozi Hanisa Musa (National Blood Centre, Malaysia)
The Rh blood group system is the most complex, polymorphic and immunogenic protein-based blood group system in humans. Some individuals produce a weak expression of D antigen on RBCs surface as a result of missense RHD mutations and amino acid substitutions that lead to distinct serologic phenotypes and anti-D immunization. This study aimed to elucidate the molecular genetic basis of weak D phenotypes in Malaysian blood donors with multiracial population. A total of 183 Rh-negative blood samples were phenotyped for D, C, c, E and e antigens. Weak D samples that identified by indirect antiglobulin test (IAT) were amplified by polymerase chain reaction-sequence specific primers for weak D type determination. A total of 183 multiracial Rh-negative donors were reviewed, consisting of 88 (48.1%) Indians, 56 (30.6%) Malays, 23 (12.6%) Chinese and 16 (8.7%) other minority ethnics. Four samples were found to be positive for weak D phenotype using IAT. Of these four samples, two samples were reported with weak D type 15. Both samples were from Chinese blood donor with DweakCcee and DweakccEe phenotype, respectively. This study provide the first database of a molecular basis of weak D in Malaysian blood donors which improved the understanding of molecular mechanisms underlying D antigen expression in Malaysian population. Thus, increase the transfusion safety in highly racial mixed population.
9:45 Analysis on Persistence of Perfume on Different Fabrics by Using Gas Chromatography Mass Spectrum
Noor Hidayat Abu Bakar (Management & Science University, Malaysia)
The research was focused on the identification of organic components in original Eau de Parfum (EDP) and Eau de Toilette (EDT) perfume by headspace solid phase microextraction (SPME) followed by the gas chromatography mass spectrometer (GCMS). The SPME fiber used in this method contain a dual coating of divinylbenzene and Carboxen, each of them was suspended on polydimethylsiloxane that was very useful in absorbing the selected organic components in EDT and EDP perfume after they were sprayed on the different fabrics. The compounds were identified by using the NIST library and the column used was capillary column with 30m x 0.25mm ID x 0.25 µm df measurement. For oven temperature, the parameters were selected at 50oC for 1 min, ramp 5oC/min to 150oC, ramp 25oC/min to 275oC/min and hold 3.8 min. During separation of the compounds, the helium gas was used as a carrier gas. In addition, EDP perfume on nylon fabrics showed that a total of six compounds were completely vaporised during the day two which were included of d-limonene, cyclohexene, 1-methyl-4-(1-methylethenyl), limonene, 1,4-cyclohexadiene and 1-methyl-4-(`-methyl ethyl). In GCMS analysis, nylon fabrics started to show that almost half of the original ingredients in the perfume had completely vaporized after two days of exposure. However, cotton fabric manages to maintain the highest ingredients found on chromatogram after two days of exposure. In laundry durability test, the result shows that after eight washing cycle cotton fabric has the highest intensity of odor compared to nylon fabric.

Previously, unregulated and rampant bauxite mining activities in Kuantan, Pahang have been seriously polluted the rivers and oceans nearby Sungai Pengorak and Pantai Pengorak. Similarly, the air quality in the vicinity was also affected by the bauxite mining activities. Red water and red dust were common in the area, and Kuantan was regarded as Mars on Earth by local communities and local press. News and rumors spread on the issue were found to be contradictory. Although some of the news were true, several articles regarding the issues was sensationalized. For instance, reports on treated water obtained from treatment plants in Bukit Sagu and Bukit Goh (i.e. bauxite affected areas) contained significant concentrations of aluminium, iron and arsenic beyond allowable limits. On the contrary, study conducted on bauxite contaminated water showed very low concentrations of these ions exist. Thus, misconceptions and fear were heightened among Malaysian, particularly, the people living in the area. This paper highlights the environmental issues pertaining to the previous mining activities covering air and watercourse pollution. Recommendations on the solutions of such problems are also discussed.

The consumption of natural products and its supplementation in traditional and complimentary medicine has always been the mainstay of treatment of diseases and ailments especially in developing countries. With the advancement in medical therapy and technology, the concurrent use of natural products to remedy numerous illness does not abate and the trend has increased over the years. Natural products of plant origin initiated herbalism, an ancient tradition of application of herbs for their healing properties. Different parts of indigenous plants have been selected and harnessed for their varying therapeutic effects and methods of administration ranged from herb-infused tea, honey, oil, creams and poultices. The effects of natural products on the growth of cells and their restorative properties have been documented in numerous studies and their bioactivity is driven by the various chemical compositions and the active ingredients in each type of plant. The application of natural products to treat infertility and problems associated with sexual dysfunctions has long been practised in traditional remedies in pursuit of preserving lineage. Assisted Reproductive Technology (ART) is a set of techniques comprising of methods such as artificial insemination and in vitro fertilization (IVF) to achieve successful pregnancy. Work using prominent natural products in ART and their effects on the reproductive cells and embryo have shown potential in the merge of old practices to new techniques to achieve fertilization of quality and in ameliorating adverse environmental effects impacting fertility.

Protein-based biopolymers such as collagen and gelatin are frequently used in biomedical and tissue engineering applications due to their inherent biocompatibility, biodegradability, and availability of binding sites for cell attachment and growth. Modification of these biomaterials allows custom-made properties for specific application, the control of drug entrapment and release, and the regulation of cell behavior. Crosslinking agents can be used to modify and improved the properties of protein-based biomaterials. The aim of our researches is to investigate green techniques and crosslinking agents for the modification of collagen and gelatin. One such crosslinking agent is genipin, a naturally occurring chemical compound. This crosslinking agent was used to improve the mechanical structure of gelatin hydrogel loaded with curcumin and for regulation of curcumin release. This presentation will include our findings on this study and also introduce our research on collagen and gelatin-based biomaterials.

2:00 ERP Solution as an Enabler of Sustained Business Process Innovation: A Case Study Using the Lens of Absorptive Capacity Theory in a Distribution Company
Noli A. Frias (Zuellig Pharma Corp, Philippines); Nelson J. Celis (DLSU, Philippines)
Considerable investments in terms of time, people and finances have been made by multinational companies in enterprise resource planning (ERP) systems in order to drive organizational innovation. The primary importance has been placed on innovative business process which has become critical given the increasing mergers and consolidations, the rise of multi-nationals, and the trend towards globalization. Organizations argue that the value proposition of ERP system is business process innovation (BPI), however, empirical studies show that such innovation is often triggered but not sustained, worse, financial losses are incurred. In this study, the contributory factors that influence the sustainability of BPI were explored by conducting a case study in a multinational distribution company.
2:15 Communication Sovereignty: Indonesia Commercial Television Case
Irwansyah Irwansyah (Universitas Indonesia, Indonesia)
Discourse of sovereignty is an important concern amid globalization and development of information and communication technology. Broadcast media become a spotlight in public sovereignty because it uses public frequencies of electromagnetic spectrum. The spectrum is regarded as an absolute state sovereignty controlled by the state, on the other side, globalization force the electromagnetic spectrum open to public and it has been commercialized. Globalization allows and interferes the local broadcast industry for foreign ownership, content, media workers, and technology. This article proposes and discusses about the measurement that could give the portion of the sovereignty on broadcast industry as a part of communication sovereignty. Two of commercial televisions have been chosen according to the annual report that could be found in the official website of television. By using a convergent parallel mixed methods design, this study reveals that the chosen commercial televisions give low portion on communication sovereignty for Indonesia.

The construction industry in Malaysia, as in many other countries, is considered one of the riskiest industries due to the high rate of accidents and their devastating consequences. The construction safety has been debated for centuries with numerous research on the methods, techniques and interventions in order to minimize accidents occurred on site. Safety and Health performance is influenced by, among other things, stakeholders' attitude towards the safety of the construction workers. The main objective of this research is to identify the attitude of the main stakeholders towards the duties and obligation of the Designer, Contractor and Client in terms of safety and health. The respondents of this research are the designers; Architects and Civil Engineers, Contractors and other stakeholders that may influence the safety and health of the construction site. Questionnaire was used as the main instrument on a Likert-type scale with a total of 97 respondents received. The research found positive results gain on the attitudes of the stakeholders towards the duties and obligation of the designers, contractors and clients. However, this does not diminish the importance of increasing the awareness on the duties and obligation of these stakeholders in terms of safety and health of the construction workers. Thus, the research suggest three recommendations for future direction of implementing design safety in Malaysia; approach curricula in the universities and colleges level, training programmes and includes the awareness in terms of safety and health of the construction workers.

The success of a construction project is evaluated through parameters of quality, cost and time. Construction companies use modern tools and technologies to enhance the quality, cost and time in their supply chain. However, the fragmented situation in the construction has left the Industrialized Building System (IBS) supply chain troupes with obvious problems in term of effectiveness. Although efforts have been undertaken to increase the IBS practice in Malaysia, the challenges of integration among the players have increased from IBS. The main study is to justify the importance of IBS to the economy and the issues in the Supply Chain Management (SCM) integration system of IBS in Malaysia. The aim of this study is to determine current opinion related to the key factors of IBS and SCM effectiveness from contractors' perspective. The methodologies are based on detailed literature review, questionnaire, interviews and survey via e-mail which were conducted among the contractors who used IBS in their projects. Through literature review, the definition, approach, development of IBS in the construction industry was studied. The results of the pilot study indicated that the importance of IBS to a company is an added value. The issues in the SCM integration system of IBS in Malaysia are price offered for IBS commercial conventional is the issue in the supply chain integration system of IBS. This result is determined by using Relative Important Index (RII) calculation. By analyzing the pilot study, the results indicate that the advantages of SCM are still far from being fully understood and recognized. To conclude, the relationship between contractors and other IBS players influence the implementation of the SCM concept. Furthermore, SCM integrated with IBS can be remarkably effective in each quality stage in order to reduce the time and expenses.

Little is known about the water retention performances of different substrate types within extensive green roofs in Malaysia. Thus, this research focused on the runoff retention performance within extensive green roof system with respect to different substrate types in Malaysia. A total of six green roofs were constructed with four being vegetated and two left unvegetated with bare soil acted as control. Four test beds were vegetated with Axonopus compressus (cow grass) and portulaca grandiflora cultivars (sedum) in both pot soil and burn soil, respectively. The runoff volume was measured volumetrically through connected to an surface runoff harvesting tank under the test beds. Water retention was calculated from the difference between rainfall and runoff volumes from each test bed. Results showed that burn soil was the most effective substrate type in retaining runoff water. The test bed with sedum planted in burn soil performed the best runoff retention efficiency in extensive green roof system in Malaysia.

Alina Irsainova, Aigul Mussabayeva, Sudheesh Thiyya Kkandi and Jong Kim (Nazarbayev University, Kazakhstan)
Foundations for mast arm/overhead cantilever structures supporting highway signs, signal, and luminaires, in hurricane prone areas should be sufficient to resist the torsion and lateral load caused by severe wind loading. In some instances, such structures are to be installed on top of highway embankment and the proximity of embankment slope may adversely influence the torque resistance of the foundation. However, the degree of reduction in torsional resistance due to the closeness of a slope was unknown. A numerical investigation of drilled shaft foundations supporting mast arm structures located near an embankment slope in cohesionless soils was performed. The torque resistance was found to reduce by a maximum of 22% when the slope angle was varied from 0 to 340 (i.e., 0 to 1V:1.5H). The study revealed that the degree of reduction is a function of the embankment height and the distance between the shaft face and the crest line; whereas, independent of the friction angle of soil. It was also identified that the equivalent level ground approach typically used in the industry practice is adequate for smaller embankment heights; but over-predicts in case of larger embankments.

A 100 preliminary thermal cycles were conducted for this material to observe the variations in the temperatures, heat flow and weight of the material. From the results of this investigation, it is shown that this material may be able to use as latent heat storage material but the remaining thermal cycles can be continued up to 1000 cycles to confirm the material for medium temperature solar thermal energy applications.
4:00 Treatment Efficiency of Riverbank Soil in Treatment of Bauxite Contaminated Water
Mohd Yuhyi Mohd Tadza and Angeline Tan Yee Ling (Universiti Malaysia Pahang, Malaysia)
Unregulated and rampant bauxite mining activities in Kuantan, Pahang have caused severe deterioration to nearby Pengorak River and Pengorak Beach. Commonly, surface water is treated by using conventional water treatment method that involved coagulation, sand filtration and disinfection process. However, conventional approach was found to be less effective in treating bauxite contaminated water in the vicinity. In recent years, the use of economical and cost-effective alternative such as Riverbank filtration system has gained widespread acceptance as a reliable method in treating raw water. This paper evaluates the treatment efficiency of riverbank soil in Pengorak River in treating bauxite contaminated water. A laboratory scale fixedbed filtration column test was conducted. Improvements in the water quality were then assessed following Malaysian Department of Environment Water Quality Index (DOE-WQI) and classified according to Interim National Water Quality Standards, Malaysia (INWQS). Water Quality Index (WQI) was determined on the basis of nine physico-chemical parameters, namely pH, color, turbidity, dissolved oxygen (DO), total dissolved solids (TDS), total suspended solids (TSS), ammoniacal nitrogen (AN), biological oxygen demand (BOD) and chemical oxygen demand (COD). Test results showed that, based on WQI and INWQS, the bauxite contaminated water in Sungai Pengorak was initially classified as Class IV and Class V (i.e. highly polluted), respectively. Interestingly, after column filtration test, the water quality improved significantly to Class I (clean) and 95.65 with respect to WQI. Due to close proximity to the sea, a much higher TDS value was obtained. The increased in TDS value may be attributed due to migration of salt during high tide and remained within the riverbank soil. Overall, the treated water complied with the National Drinking Water Quality Standards (NDWQS). Thus, riverbank filtration system may be a viable option for treating bauxite contaminated water.

This paper discussed the performance of concrete bridge pier due to earthquake loading by using LUSAS. This research included analysis of the seismic behaviour of concrete bridge deck. An analysis was conducted by using real earthquake records. The variation of normal stresses under seismic loading on the bridge deck in vertical direction is high compare with stresses in horizontal direction seems to be low. Overall the bridge deck can safely withstand by a variation forces and it is achieved based on the determined stress and displacement from the seismic load. This study has demonstrated a nonlinear analysis capable of capturing an extreme loading under seismic excitation which can be very effective in assessment of the damage and stability condition of the bridge deck. In the case of Kepong Bridge, Kuala Lumpur such analysis proved that the bridge suffers damage but remain stable. The result of this analysis shows that the bridge pier suffers some damages but it still remains stable. The result was captured using LUSAS 14.3 software which means that the software able to analyze a seismic response. The research also provides evidence on a nonlinear analysis that able to capture an extreme loading under seismic excitation which is very reliable in assessing the damage and the stability condition of the bridge pier. Based on the damages during the analysis under time history, it can be said that Kepong Bridge, Kuala Lumpur is still save under earthquake load which is the maximum ground acceleration of the earthquake is 0.012g.

The practice of conducting Industrial Training at tertiary educational context is to foster the university and industry linkage. However, critiques on the need for university curriculum to align itself with the demands of the professional workplace needs are rife. The purpose of this paper is to examine the elements of Cognitive Apprenticeship Theory (CAT) that complemented the Industrial Training contexts with relevance to the English language curriculum planning processes. As an exploratory case study, it construes that the Industrial Training context and CAT elements, anchored in Vygotskian Zone of Proximal Development (ZPD) theory, are complementary. This mixed method study employed survey questionnaire and interview and the results were analysed using descriptive statistics. The findings revealed that the Method domain of CAT which consists of modelling, scaffolding, fading, coaching, articulation, reflection and exploration is inherent in Industrial Training context. The study concludes that the language curriculum developer has to seriously consider the process of defining the Industrial Training context as "environment" which from CAT perspective encompassed of lesson content, the pedagogical approaches, the arrangement of activities promoting learning, and the sociology of learning.

In the national higher education shift towards nurturing holistic graduates with entrepreneurial mindset, the basic course of Entrepreneurship has since become a core and compulsory in all undergraduate programmes. The course was taught in the second year of a 4-year undergraduate Civil Engineering Technology programme. With only formative assessment adopted for the course, the cognitive domain assessment was based solely on the submission of 5 Assignments and sitting of a single Test in the 14-week semester. Both tasks were aligned to meet the Course Learning Outcome with emphasis on knowledge acquisition, i.e. to explain the concept and fundamental tenets of entrepreneurship, levelled at tier 3 of the cognitive domain learning taxonomy which corresponds with 'application'. The Assignments and Test were organized according to the sequential chapters of the course, helping students to gain understanding of the subject in tandem with and the learning of other core technical courses. Analysis of the cognitive task assessments showed areas of strength and weakness among the students with respect to entrepreneurial concepts, shedding light on the learning inclination and interest of technical students in a generic course as this.
10:15 Flipped Classroom At the Defence University: The Initial Reactions of Students
Jowati Juhary (Universiti Pertahanan Nasional Malaysia & Malaysia, Malaysia); Ahmad Fahimi Amir (Universiti Pertahanan Nasional Malaysia, Malaysia)
Flipped classroom is not new in the education landscape. When an instructor asked the students to read page 4 of the textbook, for example, and the next class would be dedicated to discussing and debating what page 4 is all about, it is considered a flipped concept. This is because the definition of flipped classroom has not changed over time; the only thing that changes is the medium of teaching and learning. Today, flipped classroom suggests that the students are expected to read/watch/listen to the lectures through the learning management system (LMS) or an e-learning portal before coming to the classes. What traditionally was practised is that students were given lectures during face-to-face sessions. Now, students do their 'homework' with the help of the instructors during face-to-face sessions. This paper aims at presenting the initial findings of the bigger or main research through data collected during the pilot study. Although the objectives of the pilot study are to first counter check the items in the survey and second to gauge the understanding of students of the items, the researchers argue that the initial findings are representing some critical issue in order to implement flipped classroom university wide. 78 respondents were chosen to undergo the pilot study which was divided into two phases. The data were gathered from 58 respondents who completed the survey successfully out of 78 invited respondents. The findings convince the researchers that flipped classroom would allow for the development of critical and analytical thinkers for the nation.

Abdul Samad Abdul Rahman and Mohd Jamaludin Md Noor (Universiti Teknologi MARA, Malaysia); Ismacahyadi Bagus Mohd Jais (Senior Lecturer, Malaysia); Mohd Raizamzamani Md Zain (Universiti Teknologi MARA Malaysia, Malaysia)
Residual soil is a product of weathering of parent rock and it remains in place with the original rock texture completely destroyed. Nowadays, due to increasing of population, the development in the country is growing rapidly. There also increase the number of major civil engineering construction projects that involved in residual soils. The residual soil is a widely used as construction materials such as dams, airports, road highways, foundation, embankments, slope and others. Moreover, the strength of soil is the movement of molecules that connected with each other. The result of soil strength must be efficient to the purpose of carrying various stresses of buildings installations and loads. There are many ways to investigate the soil strength. But the common way are used is triaxial test. In this research, study were made do determine the shear strength of granitic residual soil for each effective stress of 50, 100, 200 and 300Kpa and compared to soaking of specimens for the same applied effective stress for 14 days each. Analysis were made do determine the effective between unsoaked and soaked for 14 days specimens in order to replicate the real behaviors of true shear strength of the soil.

Abdul Samad Abdul Rahman and Mohd Jamaludin Md Noor (Universiti Teknologi MARA, Malaysia); Ismacahyadi Bagus Mohd Jais (Senior Lecturer, Malaysia); Mohd Raizamzamani Md Zain (Universiti Teknologi MARA Malaysia, Malaysia)
Residual soils are weathering products of rocks that normally found under unsaturated conditions. Residual soil with the excessive weathering of parent rocks can cause collapsible soil deposits. These types of soil have higher possibility to failure when wetted. Due to that many slope failure occur due to an increase of the pore water pressure that mostly been neglected in design process. The important to get the knowledge of the characteristic of the granite residual soil give the most important information of the soil strength and its behavior for the safe usage and more economic for geotechnical construction design.

9:30 Dual Role of Microalgae: Carbon Dioxide Capture Nutrients Removal
Fares Almomani (Qatar University, Qatar)
This study evaluated the use of mixed indigenous microalgae (MIMA) as a treatment process for wastewaters and CO2 capturing technology at different temperatures. The study follows the growth rate of MIMA, removals of organic matter, removal of nutrients from synthetic wastewater and its effectiveness as CO2 capturing technology from flue gas. A noticeable difference between the growth patterns of MIMA was observed at different CO2 and different operational temperatures. MIMA showed the highest growth grate when injected with CO2 dosage of 10% and limited growth was observed for the systems injected with 5% and 15 % of CO2 at 30 ◦C. Ammonia and phosphorus removals for Spirulina were 69%, 75%, and 83%, and 20%, 45% and 75 % for the media injected with 0, 5 and 10% CO2. The results of this study show that simple and cost-effective microalgae-based wastewater treatment systems can be successfully employed at different temperatures as a successful CO2 capturing technology even with the small probability of inhibition at high temperatures.

Construction Waste Management is part of a growing movement towards a sustainable world. Throughout the years, the construction industry has made an important contribution in the lives of society in Malaysia. With the demands of major residential housing project developments, it shows that the construction sector is being expanded and developed. Moreover, it has been observed that the construction waste is one of the priority waste streams. Due to the increasing population that is actively involved in economic activities and the modernisation of the country, the types of construction wastes that is being produced is becoming more complex and has yet to be identified. Therefore, the established system to record quantitative data for the generation of construction waste has yet to be formally standardized and is still lacking across much of Asian and developing countries. To address this need, the study on the major types and composition of construction waste generated is carried out as a logical first step towards assisting the construction waste management through the categorization of construction waste in Klang Valley and Pulau Pinang. Throughout this study, useful information concerning waste assessment data is necessary to achieve a better understanding of construction waste obtained. Case studies involving quantification and classification of construction waste for several on-going residential housing developments in Klang Valley, Selangor and Pulau Pinang have been presented. This paper concludes with the identification of database information concerning the quantification of local construction waste which was developed for the current practices of construction waste management.

11:00 Characterization of Genipin-Crosslinked Gelatin Hydrogel Loaded with Curcumin
Masrina Mohd Nadzir, Lau Sin Mun and Chan Pei Juan (Universiti Sains Malaysia & School of Chemical Engineering, Malaysia)
Gelatin hydrogels are attractive for use in biomedical applications due to its well defined structural, physical and chemical properties. This study aimed to evaluate the physicochemical properties of crosslinked gelatin hydrogel incorporated with curcumin and the release characteristic of curcumin from the hydrogel matrix. The addition of naturally occurring crosslinking agent, genipin has improved the mechanical strength of the gelatin hydrogel. Low concentration of genipin (0.1% w/w) added to gelatin solution prior to solidification resulted in average pore size more than 1000% larger than the average pore size of un-crosslinked gelatin hydrogel. However, average pore size was reduced with further increased in genipin concentration. This is accompanied with decreased in swelling capacity of hydrogel. Curcumin entrapment and release analysis confirmed that the alteration of pore size through crosslinking with varying genipin concentration enabled the controlled release of curcumin from hydrogel matrix.
11:20 CFD Modeling of Asphaltenes Deposition Rate From Crude Oil Through Discrete Phase Simulations
Sampath Emani, Marappa Gounder Ramasamy and KuZilati KuShaari (Universiti Teknologi PETRONAS, Malaysia)
Crude oil fouling in processing equipment's have been a major unresolved problem in process industries. The underlying behavior of the fouling precursors present in the crude oil have to be investigated to mitigate the deposit formations. In the present work, an attempt has been made to predict the asphaltenes deposition rate from crude oil in a heat exchanger tube through discrete phase CFD simulations. Various forces such as stochastic collision, DEM collision, Saffman lift, coalescence and drag are applied on the particle momentum to understand the transportation and adhesion mechanism of the asphaltenes particles. As asphaltenes have the tendency to aggregate irreversibly with different particle sizes, the transportation of asphaltenes particles is studied through varying the particles diameters. The propensity of asphaltenes particles in a Lagrangian frame is studied through the available discrete phase models in the commercial CFD software Ansys Fluent.

Estimation of rock permeability (k) is an important aspect of petroleum engineering, often accomplished by using correlations based on water saturation or pore configuration or both. However, utilizing a correlation to determine k without knowing the pore configuration of the rock for which the correlation was originally developed can yield ambiguous results. An erroneous k can lead to incorrect reservoir performance estimation and improper development plans. This study demonstrates the need for defining the pore configuration in order to select a specific model for k estimation with a greater degree of confidence. To accomplish this, thin section petrography and petrophysical properties of several rock samples were analyzed. The measured k values of these rock samples were compared with the k values estimated from several published correlations. The accuracy of each correlation as compared to the measured values was categorized on the basis of rock fabric. Thus, an intuitive guideline was developed as to which correlations are applicable to a given rock.

Foam flooding is utilized to overcome several drawbacks of gas flooding including viscous fingering and density segregation. In order to model the foam behavior inside the porous media, various studies have been conducted and several models developed. Some of the commercial reservoir simulators equipped with these foam models. However, they prefer to utilize customized model in their simulators. The contribution of each model parameter and their effect on the foam behavior are varied between different simulators. This study aims to compare two different well-known foam models and reveal the contribution of foam model parameters using the numerical simulation study. A synthetic model for Surfactant-Alternating -Gas flooding in sand pack system is built using simulators. Design of Expert is utilized to design different simulation scenario based on different foam models parameters. Simulations were performed for all scenarios and the results are analyzed by ANOVA to investigate the effect of different parameters on foam mobility reduction factor. The results show the effect of each parameter on mobility reduction factor in both models. Also, it illustrates that some parameters like critical water saturation are not important in ECLIPSE and CMG models however it has a moderate effect on foam mobility reduction in UTCHEM model.

Premenstrual syndrome (PMS) refers to a common psychosomatic disorder which about 30-50% of woman in the childbearing age suffer from mild to moderate form and 3%-8% suffer from it in its severe form. This study was undertaken to determine the association between premenstrual syndrome and quality of life and to identify the most common physical and psychiatric symptoms of premenstrual syndrome and determine the management of premenstrual syndrome among female students. A total of 300 female university students were respondents involved in this study and data were collected through self-administered questionnaire. Questionnaire was developed which included socio-demographic, obstetrical history, symptoms of PMS and management of premenstrual syndrome. Health related QOL was measured using Short Form Health Survey (SF-36). Data obtained were then analyzed using Chi square, Anova and independent T tests. This study revealed that the prevalence of PMS among the studied respondents was 69.7% and among them, 8.3% had severe form of PMS. While the mood swing (90.9%) and backache (78.9%) was identified as the most common psychiatric and physical symptoms respectively. The study also showed that the burden of PMS on health related QOL was on those with PMS whom had lower scores in all scales. There is no significant differences were observed between scales of QOL according SF-36 in category of PMS. The most commonly used practice to overcome PMS symptoms was warm bathing (72.7%). Conclusively, PMS adversely affects QOL among female university students and is an important health problem. PMS is a prevalent yet undertreated which contributes to a disordered life among women. Therefore, to improve QOL of female students, constructive support should be provided to the affected female individual.

Atrial Fibrillation (AF) is one of the most challenging heart ailments to be detected due to its nature being intermittent in early stage of its presence. The challenges become greater when early detection found to be the best treatment method. Currently, guidelines for the early detection and treatment of occult AF are limited. Electrophysiology study is most reliable noninvasive screening method used in AF detection. Electrocardiogram (ECG) is the present electrophysiological measurement in clinical practice. In this study, photoplethysmogram (PPG) based physiological measurement is introduced through heart rate variability and cardiac cycle fitness as the potential AF screening index. Seven subjects, one normal and six clinically confirmed AF patients' PPG were recorded. All patients' blood profile (INR and blood glucose) and blood pressure measurement were retrieved from pass clinical record. Infographic and data visualization technique were adopted in presenting the AF presence in PPG signal. This preliminary result has provided a foundation for AF detection by using PPG waveforms. PPG is known for its simplicity in terms of cost and utility which able to provide an opportunity to be introduced as home-based AF monitoring tool.

In the seaport industry, the port operators need to undertake maintenance dredging to maintain depths of its harbour basin and navigational channels for the safety of the vessels against the accumulation of marine sediments. For a successful maintenance dredging project, appropriate types of procurement systems must be employed by the port operators. This paper provides an overview of the procurement systems used for maintenance dredging projects at two Malaysian seaports, i.e. Johor Port and Port of Tanjung Pelepas. Structured interview with respondents from the procurement department and technical department of both ports were employed to elicit relevant information and data. Two types of procurement system that is competitive bid and direct award are implemented in both ports. The selection of procurement system depends on factors such as condition of channel, complexity, size, price, and time urgency of the maintenance dredging project. For recurring maintenance dredging, competitive bid is employed, whereas for emergency maintenance dredging, direct award is typically used by both port operators.

Movement of rubber membrane during consolidation stage into the interstice of the cylindrical specimen during triaxial testing is called as membrane penetration. At the consolidation stage, cell pressure is elevated, causing membrane penetration to occur. Membrane penetration at this stage affects the calculation of the specimen volume. Thus, stress-strain interpretation during shearing stage will be affected. Therefore, more research is needed to investigate the behavior of membrane penetration effect in granitic residual soil to aid engineers in making good analysis and design. This paper presents triaxial testings on granitic residual soil grade V under effective confining pressure of 50, 100, 200, 300 and 400 kPa. The testing involved real specimens and dummy specimens. For real specimens,compacted granitic residual soils in cylindrical form with initial diameter 50mm and 100mm height were used. Meanwhile, dummy specimens were formed by thin layer of the soil material enclosing a solid rigid cylindrical core and were used to observe purely the behavior of membrane penetration eliminating the effect specimen compression. This is to test the applicability of the graphical method proposed by (Md Noor, Nyuin, & Adnan, 2012)1 in finding the effect of membrane penetration in consolidated drained triaxial tests for the test soil.

Curing is maintaining a sufficient water and temperature in concrete through its early periods to get the aimed properties of concrete. Curing is critical in production of concrete to ensure that concrete will have the durability and strength. In order to make the concrete cured by itself, a chemical called Polyethylene Glycol 400 is used where it helps in water retention throughout the concrete during curing process. In this project, Polyethylene glycol and fly ash were added as a self-curing agents in mortar to determine the effects of self-curing agents in term of Compressive strength. The mortar ratio was 1: 2.75 (cement: sand). Polyethylene glycol (PEG) was added first with different percentage 1%, 2% and 3% by weight of cement. Then, fly ash was added with different percentage 20%, 40%, 60, 80% and 100% by weight of cement. The w/c ratio was 0.45 to ensure the workability. All mortars were exposed to the fresh air (in the laboratory environment with 25 °C) for curing to see the effect of self-curing agents. The result showed that, self-curing agents have improved the strength of mortar. The mortar using polyethylene glycol has scientifically increased the strength by 31% compared to conventional mortar. And 1% was the optimum percentage. Fly ash enhanced the early age strength by 80% compared to normal mortar. Also, 20% of fly ash was the optimum percentage.

Yusuf Latief, Lukas Sihombing and Ayomi Dita Rarasati (Universitas Indonesia, Indonesia); Andreas Wibowo (Ministry of Public Works and Housing, Indonesia)
One of the largest impediments to toll road development is land acquisition. In an ideal perspective, the required land should be acquired before a toll road project begins. However, the reality often does not meet the expectation. The government, which should accept the liability in the first place, often finds it difficult to afford it. Given the stringent budget constraints of the government, project sponsors, for many reasons, should not be expected to take on the full responsibility of dealing with it either. Innovative instruments other than that practiced now must be fostered. In this paper, a discourse on the application of a land lease model is provided. This has been widely used in many other countries, and a set of success factors has been identified to make this model work in Indonesia. A total of 23 critical success factors (CSFs) have been identified from a literature review. A Delphi survey involving a panel of knowledgeable experts was employed to examine toll road authority, guarantee institution, and private investor group variables. Based on the survey, it has been found that the quality of land lease data, the design plan and integrated location, the transparent negotiation on an investment agreement, as well as agreements negotiated to protect private investors and the government were the most important CSFs.
