Authors: Ahlafi Hanane , Noura Noura , Bahoussa Abdelaziz , Hassainate Mohammed 
Published: July 2024

Ecology as a strategic variable has been the focus of interest for researchers since the early seventies (Marguerat & Cestre 2002). As early as the pioneering researches of HÃ©nion (1976), Kassar Jian (1971), Kinnear and Taylor (1973) and Kinnear et al (1974), the ecological dimension had been integrated into the research and practice of management and marketing. In addition, some authors agree that different stakeholders such as consumers, NGOs, public authorities, advertisers and publicists are increasingly informed and aware about the importance of protecting their environment (Schlegelmilch & Pollack 2005).However, some authors denounce the inaction of consumers although they are aware of the degradation of their environment. This passivity is explained among other things by the high price of green products compared to traditional products (Green Brands2011).In this study, we first presented the research problem, and then we analyzed the works related to the typologies of green consumers and the main variables that we consider to be determinants of the adoption of so-called green products. Finally, we exposed the research hypotheses, the conceptual model, highlighting the mediating role of innovativeness in the relationship between the attitude towards advertising and the adoption of green products.Â Â Â

Published: July 2024

Strategic planning has become a fashionable theme in recent years, often used to legitimize the formalization efforts of the management concept in organizations. This is a central theme in organizational theory, but it remains hard to access. The purpose of this article is threefold. It first presents a state of knowledge on the subject of this basis. It then proposes a model referring to the main steps for strategic formalization. And finally, it allows us to situate the relationship between strategic planning and performance in Moroccan organizations. These theoretical contributions are increasingly being used to analyze the contribution of strategy in improving the performance of organizations as Winston Churchill said: â€œLet the strategy be beautiful is a fact, but do not forget to look at the resultâ€.Â Â

Authors: W. Dahham Khalid , Baharom Shahrizan , S. Majdub Mohamed 
Published: July 2024

In this study, 3-D finite element models were used to investigate the performance of a continuous composite slab (CCS) with profiled steel sheet strengthened by CFRP laminates in a negative moment region. FE models were validated using available experimental data before being used for parametric studies. The parameters were the number of CFRP, slab thickness and concrete strength. The results obtained from the finite element analysis of the strengthened CCS models agreed well with the experimental tests where the deviation in the ultimate hogging moment is only between â€“2.0% and +3.0%. It proved that the developed FE model is capable of simulating the CCSs strengthened in the hogging region by CFRP laminate. Results have shown that the strengthening of the CCS specimen in the hogging region with CFRP laminates significantly improved its moment capacity about 23% and 91% using one and three CFRP laminate, respectively. Furthermore, increased in slab thickness and concrete strength resulted in higher load improvement.Â Â

Published: July 2024

This paperâ€™s main objective is to evaluate the quality of commuter rail service at Kuala Lumpur by conduction a commuter user survey. The study sample consisted of 400 commuter rail passengers. The results reveal that there is significant conflict between passengerâ€™s expectation and perception of the commuter rail service quality at Kuala Lumpur. Measured value for passenger expectation are found to be consistently higher than their satisfaction, which indicate that is room for Malayan Railways Limited (KTMB) management to improve its service quality. Three out of 12 service items such as the price of ticket, the punctuality time for departure and arrival of train, and ticket counter rated as important and satisfactory, and thus should be maintained. These items are the issues that may have caused concerns for passengers and should urgently addressed by KTMB management to improve passengerâ€™s satisfaction as well as to increase the commuter rail ridership.Â Â

Authors: Yun Tong Siow , Kasa Anuar , Aminah Osman Siti 
Published: July 2024

The main goal of isolation is to provide lateral flexibility to building foundation in order to mitigate horizontal movement resulted from earthquake event. Conventional seismic isolation system consists of elastomeric or sliding system which is costly. Recycled Tire Isolator (RTI) is a model designed to be installed at building foundations to resist earthquake forces. It is laterally flexible and has some similarities compared with commercial base isolators.RTIwas fabricated using tread sections of recycled tires which are cut into pads of 300mm x 210mm and each pad has thickness of 10mm. Adhesive was applied on the cut tire pads before they were stacked on top of each other. Pressure was imposed on theRTIto ensure the layer of pads stick well. Static compression test and dynamic load test were conducted to examine the dynamic and mechanical properties ofRTI. In static compression test, a controlled axial load of 380 kN (maximum capacity of the compression test machine) was applied on to theRTI. A displacement of 12.2mm was recorded. For dynamic load test, Servo Hydraulic MTS322 Testing Machine was used. The dynamic stiffness, damping ratio and damping coefficient were obtained and compared with the commercial isolator.Â Â Â

Published: July 2024

The ability of air-coupled impact-echo technique to retrieve data in a short time is the main advantage of this technique. However, there are some external factors, especially noise disruptions arising from surrounding sound where the test is performed causing some error to the data collected. Therefore, the use of acoustic shield is introduced. This paper presents the performance of air-coupled impact echo testing in detecting concrete flaws depth and effects of different acoustic shields on the estimated flaws depth. Testing is performed on concrete slab designed to have four defects at different depth and size. Acoustic shield are made from egg crate foam, aluminium sheet, polyvinyl chloride (PVC) pipe and polypropylene (PP) plastic. Recorded data in time domain is transformed to frequency spectrum by fast Fourier transform (FFT) to obtain the peak frequency for each defect zone. Estimated depth error obtained without acoustic shield is 10.0%. The value was higher compared to the use of acoustic shield from egg crate foam, aluminium sheet, PVC pipe and PP plastic with 3.3%, 3.3%, 8.3% and 3.3% error respectively. Data analysis shows that the use of acoustic shield has reducing the effects of noise and other acoustic waves measured by error percentage. The use of egg crate foam as an acoustic shield is the most effective shield followed by aluminium sheet, PP plastic and PVC pipes.Â Â

The urban growth affected the soaring demand of affordable house especially in the urban area in Malaysia and affected the surge of housing price due to the low of affordable housing supply. This phenomenon not only affected the low-income group but also middle income group whom facing the financial difficulties in owning a house due to the rising cost of living in urban area. Khazanah Research Institute 2015 and Bank Negara, 2015 research indicates that housing price in Malaysia is unaffordable in all major cities in Malaysia for most middle to lower income groups. The IYRES study also showed that only 39.7 percent of youths owns a home. Young executives are trapped within the middle-income range of ages 23 to 35, earning between RM 2,000 and RM 3,000 per month. they are not eligible to buy a low-cost housing due to the requirement but at the same time, are not able to purchase medium cost property. Thus, the main objective of this study is to identify the young executiveâ€™s perception on the implementation of â€˜Evohomes TMâ€™ concept as strategy to provide the affordable housing. The results indicate young executive accepting this concept to be applied to affordable homes.Â Â

Published: July 2024

Oil palm frond bagasse (OPFB) is the major agriculture waste from the production of palm oil with 0.66g/g of total carbohydrate to serve as potential carbon source for downstream processing in producing succinic acid. This study focused in determining the optimum process variable conditions for the 1% glucan loading for enzymatic hydrolysis process with commercial blending cellulase enzyme mixture of Cellic CTec 2 and hemicellulase enzyme of Cellic HTec 2. Using statistical approach of Response Surface Methodology, three independent process variables; specific enzyme activity (5 - 80 FPU/g glucan), hydrolysis temperature (30 - 70 Â°C), and agitation speed (100 - 180 rpm) were investigated at five different levels (-Î±,-1, 0, +1, +Î±). The regression models indicated that R2 for glucan conversion at 1% GL enzymatic hydrolysis was 97.2% showing the experimental variations were well-defined by the models. For the lack of fit test, the p-values > 0.05 proves that the model was significant to the prediction model. While both specific enzyme activity and hydrolysis temperature were statistically significant, there was no interaction observed between these variables. Although experimental runs reported the maximum glucan conversion of 94% was achieved in the 1% GL hydrolysis with 83.75 FPU/g glucan and 50Â°C after 96 hours of saccharification process, through validation process, the optimum conditions were determined at 30 FPU/g glucan, 45oC and 100 rpm respectively where these saccharification conditions achieved 90% glucan conversion within 72 hours.Â Â

Published: July 2024

This paper presents the application of artificial neural networks (ANN) in modeling of two continuous stirred tank heat echangers in series (2CSTHEs), which is a complex non-linear process. Non-linear models of the 2CSTHEs system were developed using ANN because ofÂ ANN ability to model complex non-linear processes without requiring any explicit knowledge about input-output relationship. The ANN architectureÂ is based on the multilayer feed forward network and it is trained using the back-propagation algorithms. Three types of back-propagation algorithms are used in the study, namely, Levenberg-Marquardt, BFGS quasi-Newton, and conjugate gradient with Polak-RibiÃ©re updates. Two dynamic models of the system are developed: ANN model for CSTHE 1and 2. Results from the study showed that the 2CSTHEs model trained using Levenberg-Marquardt algorithm produced the best predictive performance of the system behaviour. The results confirmed that ANN can be used in the modeling of the heat exchanger 2CSTHEs, and the model obtained can predict the outputs of the system process with very high accuracy. This proves that ANN modelling method can produce accurate system models that can simulate and predict the behaviour of complex non-linear processes.Â

Published: July 2024

High level of ammonia concentration in raw water have led to the temporary shutdown of water treatment plant at certain areas of Malaysia especially in Selangor state. The contamination occurred as a result of the impact of industrial activities, agricultural activities and disposal of rubbish into the river. This study was carried out to determine the performance of slow sand biofilters (BioSSF) as an alternative method for the ammonia removal in drinking water treatment plant. Two factors i.e., empty bed contact time (EBCT) (5 to 15 minutes) and ammonia concentration (3 to 5 mg/L) were investigated. The results showed the best ammonia removal percentage was at 15 minutes EBCT with removal percentage of 98.3%. Increasing the ammonia concentration in raw water reduced the BioSSF performance, but the ammonia removal was still below the regulated limits (< 1.5 mg/L). In addition, the BioSSF also have a capability to reduce the turbitidy, chemical oxygen demand, colour and suspended solid. Thus, it proved the BioSSF can be an alternative method for the current conventional water treatment specially to remove the ammonia.Â Â

Chemical composition of empty fruit bunch (EFB) is an important chemical property that determines its utilization performance in bioconversion process. Various chemical compositions of EFB have been reported, and these differences in composition affects EFB utilization in terms of conversion and product yield. Complex structure and recalcitrant characteristic of lignocellulosic biomass (LCB) also affects its utilization that leads to pretreatment system requirement. Pretreatment using deep eutectic solvent (DES), a group of ionic liquid (IL), has attracted scientific interest due to its exceptional ability in hemicellulose and lignin removal. This research determined the chemical composition of six native EFB sample collected in Malaysia, and identified composition difference among samples using t-test. The work further determined the influence of DES01 pretreatment on selected pretreated samples using enzymatic hydrolysis process. Chemical compositions of six native EFB samples, collected in Perak, Selangor and Negeri Sembilan in dry and wet seasons, were determined using National Renewable Laboratory Analysis (NREL) protocol. Enzymatic hydrolysis of pretreated EFB samples were conducted following NREL protocol using Cellic CTec2 and Cellic HTec2 enzymes for 72 hours. The t-test analysis on structural carbohydrate (SC) content of native EFB showed Sg. Siput sample (SSD) in dry season and Bahau sample (BW) in wet season had statistically significant difference where native SSD contained the highest SC while native BW had the lowest. Enzymatic hydrolysis results of DES01 SSD and DES01 BW samples indicated the influence of DES01 pretreatment. DES01 SSD substrate produced higher glucan and xylan conversion after 72 hours of hydrolysis with 92.40% and 68.71% respectively compared to the DES01 BW sample with 75.82% and 18.78% only. This could be correlated with higher glucan and lower lignin contents in However, the different composition of native EFB also affected the hydrolysis of pretreated EFB. The variable pressure scanning electron microscopy (VPSEM) analysis showed that EFB structures were destroyed by the hemicellulose and lignin removal after the pretreatment and enzymatic hydrolysis.Â Â

Published: July 2024

Microgrid can operate in dual mode; grid-connected and islanded mode. In order to seamless transfer from islanded microgrid to grid connected mode, it is necessary to voltage, frequency and phase of microgrid to synchronize with main grid to prevent severe consequence. However, microgrid has to be controlled in a coordinated way to achieve a synchronization. This paper present a review on the existing active synchronization approach with their control strategies. There are three approach for grid-connected synchronization; active synchronization, passive synchronization and open transition transfer. However, only active synchronization approach provides the reliable reconnection for microgrid. Active synchronization approach associates with control structures and control strategies. There are three control structures of microgrid under active synchronization; centralized, decentralized and distributed and three control strategies available in the literature which are phase locked loop (PLL), droop control, and frequency locked loop (FLL). The most applicable control strategy for active synchronization is phase locked loop because of its simplicity, robustness, and effectiveness in various main grid condition. Furthermore, between three control structures of active synchronization, decentralized control is becoming more favorable by the researches based on its advantages over the other structures.Â Â

Published: July 2024

Employeesâ€™ health status is one of the key issues that should be considered in ensuring the economic growth of a country. Information on employeesâ€™ health status is useful in social and economic studies, especially in issues related to work-related disabilities and deaths. The estimation of disability probability involves a challenging method as a disabled employee may move from one state to another (from temporary to permanent, or vice versa), or from one event to another (from disabled to active, or to death), implying that repeated responses may be obtained at different time points in the relevant longitudinal studies. Markov Chain Model can be used to analyze repeated measurements, or ordinal responses in a longitudinal data, and to compare between one health states to another. The main objective of this study is to estimate the Markov transition probabilities between health states using the Proportional Odds Model (POM) based on the dataset obtained from Social Security Organization, Malaysia (SOCSO). The results show that female employees in age group 55-59 have the highest probability of remaining in active state (A), while male employees in age group 15-19 have the lowest probability of remaining in active state (A), or have the highest risk of transitioning from healthy state to disability or death states.Â Â
