    Dengue fever and dengue haemorrhagic fever are diseases caused by dengue virus transmitted by Aedes mosquitoes. Dengue fever has caused a high rate of mortalities among Malaysians every year. Even though many campaigns had been conducted by the government to reduce dengue cases, the number of infected people in this country is still high. We conducted this survey to determine the status of dengue fever awareness among residents in Kuala Terengganu. For data collection, face-to-face interviews were conducted, and a questionnaire was administered. There were three categories of respondents, namely urban area residents, rural area residents and university students. Results showed that respondents across the three groups were knowledgeable regarding dengue fever issues and there was no significant difference between the three categories of respondents in the number of residents who had been involved in dengue awareness programmes. However, most of the respondents regarded the dengue awareness programmes as moderately effective and could be overcome if prevention efforts and approaches were being carried out on a continuous basis.

    This paper provides preliminary evidence ofthe need foraccounting for trash management in public organizations, in particular, UniversitiMalaysia Terengganu (UMT). It has two objectives: tosolicit opinions from students regarding their behaviorsand perceptions towards recycling habits,and to provide data on the extent of accounting for trash management at UMT. A survey among155 UMT students indicatedthat theyrecycled the trashandwereaware of environmental issues caused by the waste. However, they were not informed about the benefits of environmental management accounting practice particularly regardingtrash management. Interviewswith UMT management also revealed that while UMT supported recycling activities byfunding the projects and providing facilities, the data on the opportunity cost involved in the current practice was never integrated into UMT accounting system. As a result, the management hadno idea of how much was lost (or gained) during the process. Based on the findings,this study callsfor the implementation of accounting for trash management in a public university.

    Learning preferences among undergraduate accounting students might vary considerably and are still largely unexplored although their findings might be useful for lecturers to improve learning and teaching strategies. Students’ preferences in selecting the appropriate learning strategies can help improve their understanding and lead to improved competency for better academic achievement. This study examined students’ preferences towards learning strategies and the differences in learning strategies among accounting students in Universiti Malaysia Terengganu, between genders. The data were collected using online survey completed by accounting undergraduate students from Year 1 until Year 3 for the academic session 2018/2019. 150 students responded to the online survey, with 32% response rate. Using a revised two-factor version of the Study Process Questionnaire, the survey assessed deep and surface approaches in learning preferred by the students. The results showed that deep learning approach scored a higher mean of 3.36 compared to surface learning and gender was found insignificantly related to the preferred learning approach. This finding suggests that the use of deep approach (for example, active learning or student-centered learning) is to encourage better learning process that would contribute to better academic performance and teaching strategy practices among accounting students.

    Ordinary Differential Equations (ODEs) are usually used in numerous fields especially in solving the modelling problem. Numerical methods are one of the vital mathematical tools to solve the ODEs that appear in various modelling problems by determining the approximation solution close to the in exact solution if it exists. Runge-Kutta methods (RK) are the numerical methods used to integrate the ODEs by applying multistage methods at the midpoint of an interval which can efficiently produce a more accurate result or small magnitude of error. We proposed Runge-Kutta methods (RK) to solve the 1st_ order nonlinear stiff ODEs. The RK methods used in this research are known as the RK-2, RK-4, and RK-5 methods. We proved the existence and uniqueness of the ODEs before we solved it numerically. We also proved the absolute-stability of the RK methods to determine the overall stability of these methods. We found two suitable test cases which are the standard test problem and manufactured solution. We proved that by combining the adaptive step size with RK methods can result in more efficient computation. We implemented the 2nd_, 4th_ and 5th_ order of RK methods with step size adaptively algorithm to solve the test problem and manufactured solution via Octave programming language. The resulting numerical error and the stability of each method can be studied. We compared our results using several error plots versus the Central Processing Unit (CPU) time required to compute a given nonlinear 1st_ order stiff ODE problem. In a conclusion, RK methods which combine with the adaptive step size can result in more efficient computation and accuracy compare with the fixed step size RK methods.

    A wide range of studies have been conducted on deep learning to forecast time series data. However, very few researches have discussed the optimal number of hidden layers and nodes in each hidden layer of the architecture. It is crucial to study the number of hidden layers and nodes in each hidden layer as it controls the performance of the architecture. Apart from that, in the presence of the activation function, diverse computation between the hidden layers and output layer can take place. Therefore, in this study, the multilayer perceptron (MLP) architecture is developed using the Python software to forecast time series data. Then, the developed architecture is applied on the Apple Inc. stock price due to its volatile characteristic. Using historical prices, the accuracy of the forecast is measured by the different activation functions, number of hidden layers and size of data. The Keras deep learning library, which can be found in the Python software, is used to develop the MLP architecture to forecast the Apple Inc. stock price. The developed model is then applied on different cases, namely different sizes of data, different activation functions, different numbers of hidden layers of up to nine layers, and different numbers of nodes in each hidden layer. Then, the metrics mean squared error (MSE), mean absolute error (MAE) and root-mean-square error (RMSE) are employed to test the accuracy of the forecast. It is found that the architecture with rectified linear unit (ReLU) outperformed in every hidden layer and each case with the highest accuracy. To conclude, the optimal number of hidden layers differs in every case as there are other influencing factors.

    Renewable materials have some bearing on the environment and have since increased research works related to polymer composites. This work was conducted to investigate the effects of interwoven kenaf fibres and the use of kenaf fibres in composites. In this research, interwoven between kenaf and polyethylene terephthalate (PET) was prepared and epoxy was used as the polymer matrix to form composites. The kenaf fibre composites with various kenaf fibre contents (2, 5, 8, and 10 wt %) interwoven with (PET) fibres were prepared by using open mould method. The properties of kenaf/PET/epoxy composites (KPTE) were studied. The kenaf fibre composites characterization was determined based on their mechanical properties, water absorption, morphology and thermal properties. The tensile strength test was performed using Testometric machine. The finding shows that the strength increases as the amount of kenaf fibres in the composites increases. The composites with 10% kenaf fibres interwoven PET displayed the highest tensile strength (85.3 ± 2.9 MPa) while unfilled epoxy show the lowest tensile strength (64.1 ± 16.5 MPa). The addition of kenaf fibres minimally increases the water absorption up to about 1.4%. The increases of kenaf fibres also reduces the overall thermal stability of the composites compared to the PET and epoxy resin composites. The morphology properties of KPTE composites support the tensile properties surface of the composites. This study assists to propose the kenaf fibres as a potential filler for properties improvements in epoxy-based composites contributing to the development of another environment-friendly material.

    The Greek letter φ (Phi) represents one of the most mysterious numbers (1.618…) known to humankind. Historical approbation for φhas led to the monikers “The Golden Number” or “The Divine Proportion”. This simple, but inscrutable number, is inseparably linked to the recursive mathematical sequence which produces Fibonacci numbers. The study of the Fibonacci sequence exists in most aspects of life starting from the leaves of a non-flowering plant, design, paintings, animals, and even human body. Despite its wide-spread prevalence and existence, the Fibonacci series and also the Rule of Golden Proportions have not been widely documented within the human body. The main objective of this study is to prove that the length of the human hand bone is in step with the Fibonacci series to spot the degree of movement and variation for every finger. Victimization of the sample z test with 95% confidence interval, this analysis shows that just one of the four bone length ratios contained the ratio phi φ within the 95% confidence interval and follow the Fibonacci series, that of the little finger metacarpal and proximal phalanx in both hands. The largest variability was seen within the little finger phalangeal relationships and other fingers will follow mathematical relative series. Due to the relationship with the golden number, it will facilitate in monitoring the individual with an injured hand, especially if injured in small fingers throughout a medical aid, or to identify the cause of the problem of physical functioning of the hands or individual fingers. Hence, it should be helpful for the length of the clenched fist to perform in reconstruction or placement of the prosthesis.

    This study examined biological asset information that has been reported by companies in Malaysia and the methods of valuation used in reporting the biological assets. It aimed to provide useful information to the regulators about the application of MFRS 141, the accounting standards for agriculture, in corporate reporting. This study employed the data derived from the 2016 annual reportsof plantation companies listed on Bursa Malaysia. Descriptive analysis was used to examine the biological asset information that has been reported and the characteristics of the companies such as age, size, and leverage. The results of this study showed that most of the plantation companies believed that fair value and historical cost could be the best way to measure their biological assets. The findings of this study provide input towards identifying the gap in corporate reporting practices and the challenges faced by companies in the application of MFRS 141. The findings are expected to contribute to the regulatory improvement towards increasing the full adoption of MFRS 141 by companies in Malaysia.

    The distribution of heavy metals (Cu, Zn, Cd, Pb) in surface sediments was examined in waters off the coast of Marang, Terengganu. A total of 20 samples were collected using Ponar grab and analysed by inductively coupled plasma-mass spectrometer after closed digestion with acid. The sediments were filtered using a dry sieving method to determine their particle size. The spatial distribution maps on the concentration of selected metals were drawn using the ArcGIS software. Results showed that the average concentration of Cu, Zn, Cd, and Pb were 2.33±0.38 µg/g dry weight, 28.4±3.78 µg/g dry weight, 0.09±0.01 µg/g dry weight and 8.35±1.48 µg/g dry weight, respectively. The level of pollution was also evaluated using the Index of Geoaccumulation (Igeo) and Pollution Load Index (PLI). All Igeo and PLI values obtained were low, which indicated low or no pollution. Meanwhile, the sediment mean size ranged between -0.77Ø and 3.18Ø, which characterised a sandy type of sediment. Correlation analysis showed a positive correlation between the heavy metals and sediment size. The results indicated that there was a common source of heavy metal pollution in the study area, possibly from shipping activities. Overall, there was no significant heavy metal pollution in the waters off Marang. This finding is important as the data could be used to evaluate the risk of metal contamination and the impact of anthropogenic activities on the marine environment.

    Pumpkin (Cucurbita maxima) is a vegetable crop which is commonly consumed as vegetables or incorporated into food products. Pumpkin flesh was reported abundant with carotenoid compounds includes α-carotene, β-carotene, β-cryptoxanthin, lutein and zeaxanthin. As this antioxidant related to the colour pigment, these nutrients highly potential to be in other parts of pumpkin such as peel and seed. Therefore, the aim of this was to determine the total lutein content in different parts of pumpkin and their antioxidant properties. The pumpkin would be collected and evaluated at the commercial maturity stage (60% to fully orange-yellow of fruit peel). The presence of the lutein properties using DPPH, FRAP and ABTS assays in different parts of pumpkin was tested by using microplate spectrophotometer and analysed statistically with SPSS version 20. Among of all pumpkin fruit parts, flesh presented the highest concentration of potential lutein extracts, followed by peel and seed, respectively. On the contrary, potential lutein extracts from the pumpkin peel had the highest antioxidant activity in terms of DPPH, FRAP and ABTS assays when compared to the lutein extracts in flesh and seeds. This study indicates that the potential lutein from Cucurbita maxima especially peel may be the alternative to be used as both natural antioxidants in food products due to increasing demand for natural food preservatives. Therefore, this study may act as a source for others to further study to optimize the usage of pumpkin by-products

    There are various teaching methods developed in order to attainsuccessful delivery of a subject without prior knowledge of the interaction among the students in a class. Social network analysis (SNA) can be used to identify individual, intermediate and group measures of interaction in a classroom. The idea is on identifying ways to boost the students’ performance by means of lecturer’s intervention based on their interaction. The case study was conducted involvingthird year batchthat consistedof 76 female and 24 male students. A friendship network was drawn based on the information obtained at the end of semester 5 and it wasinvestigated based on two metrics–centralitymeasures and Girvan-Newman algorithm. At the end of semester 5, grades were added asthe attributes of the network.12 clusters were found in this batch and a distinct pattern was identified between performing and poor achieving students. At the beginning of the 6th semester, the studentsweregiven the option to choose between 2 groups. Group 1 was unperturbed without any lecturer’s intervention whereas the performing students’ clusters in Group 1 were preserved but the students in poor performing clusters were distributed among performing clusters. The students were then asked to carry out assignments/quizzesin their respective groups. The final grades indicatedthat the performance of the students of Group 1 wasmuch superior and there wasclear evidence that those poor performing students in the 5th semester performed much better in semester 6. This shows that by understanding the students’ interaction and incorporatiniginstructor’s minimal intervention, the performance of the students can be improved by creating a social contagion effect through group assignment clustering.

    Kefir is a fermented milk obtained by fermenting milk with kefir grains. The chemical composition ofdairy and non-dairy sources may affect the growth and characterisation of lactic acid bacteria (LAB). In this study, different sources of milk (cow milk) and non-dairy milk (soymilk and coconut milk) were used as the fermentation media for kefir products. The objectives of the study were to isolate and characterise LAB from kefir drink produced from dairy and non-dairy milk. LAB was isolated using different cultural methods, such as MRS Agar, MRS with 0.8% CaCO3, and M17 Agar. The characteristics of the LAB isolates were determined using morphological, biochemical tests and the API 50 CHL kit. The physicochemical composition of the samples was determined using titratable acidity and pH level. Sensory evaluation of the kefir drink samples was also carried out. Results confirmed that the isolates were identified as Lactobacillus buchneri, Lactobacillus brevis 1, Leuconostoc mesenteroides, Lactobacillus acidophilus 3and Lactobacillus plantarum 1. The L. buchneri, L. brevis, Leu. mesenteroides and L. acidophilus are heterofermentative bacteria, whereas L. plantarum is a homofermentative bacterium. Four LAB isolates have the potential to be used as probiotic strains due to their high resistant to low pH and bile salt. The sensory scores of these products range between 5.00 and 8.00 in the 9-point hedonic scale. Most of the sensory panelists preferred cow milk kefir (p < 0.05) compared with coconut milk kefir and soy milk kefir during the sensory evaluation of all attributes. Meanwhile, the preference between coconut milk kefir and soy milk kefir was similar (p>0.05) in all attributes. Therefore, this study will be useful for probiotic manufacturers in the production of alternative probiotic drinks using dairy and non-dairy milk.

    The number of small and medium-sized accommodations (SMSAs) has increased in Malaysia in tandem with the growth of the tourism industry worldwide. The states involved in this study were Terengganu, Kelantan and Pahang. The SMSAs in these states are rated using Orchid rating, namely 1-Orchid, 2-Orchid and 3-Orchid, generated by the Ministry of Tourism, Arts and Culture Malaysia (MOTAC). This study applied the Resource-based View (RBV) theory to investigate four factors (marketing management, human resourcesmanagement, innovation capability management and information technology) assumed to be competitive capabilities that may influence accommodation’s performance. The objective of the study is to examine whether the four factors influence the performance of Orchid-rated accommodations located in the East Coast of West Malaysia. The results revealed that the four factors do not have any relationship with the accommodation’s performance. The analysis also singled out one argument of the director of SMSA that competitive capabilities are not important to their business. This argument coincides with the results of the analysis that the four factors are not significant with regards to the accommodations’ performance.

    owadays the increasing prevalence of dietary disease has raised consumers’ awareness of healthy diet and lifestyle. The rise in the use of nutrition and health claims to promote health benefits in food products help consumers make effective food choices. There is very limited research regarding nutrition and health claims in Malaysia. This research focused on consumers’ knowledge, perception (i.e. perceived quality, perceived healthiness, perceived value, perceived importance, trust and perceived familiarity), and attitude towards nutrition and health claims on dairy products as well as their purchase intention towards the products, and examinethe relationship between these variables in Johor Bahru, Johor. All responses were collected by distributing questionnaire to convenience and quota sample (n=200). Data was analysed to obtain descriptive statistics and correlation analysis. The results showed that most of the consumers (46%) had moderate knowledge of nutrition and health claims on dairy products. Consumers generally had almost positive perception and attitude towards nutrition and health claims on dairy products and positive purchase intention towards dairy products. Almost all independent variables correlated with purchase intention towards dairy products. Consumer attitude had the strongest positive relationship with purchase intention (r=0.722), followed by moderate positive correlation between consumer perception and purchase intention (r=0.671), while consumer knowledge only had low relationship with purchase intention (r=0.299). This study added new knowledge regarding public purchasing behaviour towards dairy products with nutrition and health claims. This research also provided valuable information for both food manufacturers and companies to help them make effective decisions to improve the presentation of nutrition and health claims for better expression of information as well as the goodness of food products in order to attract the attention of health-conscious consumers.

    This study focuses on the parasites in Dascyllus trimaculatus fish in Bidong Island. Though D. trimaculatus is a common reef fish, there is lack on parasites studies of this fish in Malaysia. The objectives of this study are to identify metazoan parasites and analyse the prevalence and mean intensity the parasites in D. trimaculatus. Sampling was randomly conducted on a coral colony of 100 meters within a 15m depth at Pantai Pasir Cina,BidongIsland.ThisresearchresultedintheidentificationofacopepodLernaeocera branchialis and a nematode from the family Camallanidae. The copepods collected in this study infected 20 out of 42 D. trimaculatus specimens, whereas the nematode-like parasites collected infected 18 of out of 42 D. trimaculatus. All copepods found in the gills of D. trimaculatus had a prevalence of 4.95 and mean intensity of 47.62%, while the nematode-like parasite, which were found in the brain, had 2.72 prevalence and 42.86% mean intensity. This elucidates that both parasites are categorised as having light levelbut common frequency of infection, and the current IUCN status of D. trimaculatus has not been reported to be harmedby parasites. Though the mean intensity of both parasites isnot harmful, the prevalence are concerning and might increase in the future, with further incorporation and monitoring of climate change factors that may affect the damselfish.

    This study investigates the characteristics of an antioxidant cream made from the methanol extract of Piper sarmentosum leaves, which is locally known as the wild betel or pokok kadok in Malay. The secondary metabolites of the leaves were subjected to phytochemical tests to detect the presence of natural compounds. Antioxidant activity was described by its total phenolic content (TPC) and total flavonoid content (TFC), which was assessed by 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay. A phase diagram was constructed to find a possible region to formulate an antioxidant cream. In phytochemical screening, the methanolic extract showed positive presence of alkaloids, flavonoids, steroids, terpenoids and tannins. In quantitative analysis of antioxidative components, besides having significantly higher TFC content compared with quercetin (P
