This studycould help the government to improvetaxi services in general and GrabCar servicesin sharing economy.
Tourism is associated with leisure and travelling, and is considered one of the fastest growing sectors that contribute significantly to the country’s economy, as well as bringing benefits directly to local communities. The Rural Tourism Master Plan was established in 2001, which defines rural tourism as an attraction that offers visitors the opportunity to experience Malaysia’s traditional culture and heritage away from urban areas. This study focuses on such tourism in the Gunung Mulu National Park, a famous natural park comprising underground caves, virgin rainforests and highlands. This research uses a quantitative approach with a random sampling technique because the procedure to select a unit for inclusion in a sample is much easier, quicker and cheaper. A questionnaire is distributed via Google Form to 500 local tourists who visited the park. The results of this research may be useful in marketing the Gunung Mulu National Park worldwide, besides fine-tuning programmes to attract tourists to the national park.
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.
This study aimed to determine the physicochemical properties of undulated surf clam (Paphia undulata) hydrolysate as affected by the degree of hydrolysis (DH). Three levels of DH of undulated surf clam hydrolysate were prepared which were DH 36.57% (without any enzymatic hydrolysis), DH 58.25% (0.5% Alcalase®; 5 min; pH 7.5; 60ºC) and DH 91.26% (1% Alcalase®; 30 min; pH 7.5; 60ºC). After protein hydrolysis, the undulated surf clam hydrolysates were centrifuged, and their supernatants were freeze-dried. This study found that the protein hydrolysate with lower DH (DH 36.57%) gave lower protein content and higher ash and fat contents compared to other samples (DH 58.25% and DH 91.26%). However, the carbohydrate content is similar in all samples (16.56-20.04%). This study also found that foaming properties (29.43-67.50%), emulsifying capacity (11.94-110.52%) and peptide solubility (57.61-94.08%) were affected by the DH. As DH increased, the emulsifying capacity decreased, while peptide solubility increased. While the foaming capacity increased with increasing DH until it reached a maximum value and level off afterwards. For colour parameters, although there were differences between L*, a* and b* values for all three samples, a fluctuating pattern was noted with DH. DH also did not affect the water-holding and oil-holding capacity of undulated surf clam hydrolysate. This study shows that certain physicochemical properties of undulated surf clam hydrolysate can be tailored by adjusting the degree of hydrolysis.
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.
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
Many chilli producers in Malaysia are facing a huge problem of anthracnose disease that infect the chilli fruits either at pre- or post-harvest stage. Due to this infection, the chilli fruits become rotten and could be colonized by grey conidial masses which is unfit for human consumption and cannot be sold. This study was aimed to isolate the fungal species associated with anthracnose symptoms collected from several mini-markets near Gong Badak, Terengganu. Pathogenicity test was conducted for all these isolates to evaluate their pathogenic level. Based on the results, five fungal isolates were successfully isolated and morphologically identified as Colletotrichum spp. All these isolates were labelled as UMTT46C, UMTT48C, UMTT50C, UMTT52C and UMTT54C. From these, fungal isolate (UMTT54C) showed the highest pathogenic level with disease severity (DS), 68.9%. Other Colletotrichum spp. recorded percentage of DS ranged from 53.3% to 60%. Identification of fungal isolates and their pathogenic level from the infected chilli is very important to assist in control strategy which can further provide a good protection measure for many chilli producers.
This paper aims at solving an optimization problem in the presence of heavy tail behavior of financial assets. The question of minimizing risk subjected to a certain expected return or maximizing return fora given expected risk are two objective functions to be solved using Markowitz model. The Markowitz based strategies namely the mean variance portfolio, minimum variance portfolio and equally weighted portfolio are proposed in conjunction with mean and variance analysis of the portfolio. The historical prices of stocks traded at Bursa Malaysia are used for empirical analysis. We employed CAPM in order to investigate the performance of the Markowitz model which was benchmarked with risk adjusted KLSE Composite Index. We performed a backtesting study of portfolio optimization techniques defined under modern portfolio theory in order to find the optimal portfolio. Our findings showthat the mean variance portfolio outperformed the other two strategies in termsof performance of investment for heavy tailed assets.
A study on distribution and diversity of benthic foraminifera in surface sediments was carried out in Northwestern Sarawak waters, Malaysia. The range of water depth at the study site was between 43 m and 71 m. A total of seven sediment samples were taken for this study. As a result, 11 genera were identified from a total of 1,222 individuals of foraminifera. 200 individuals were picked out from each sample. The 11 genera that were identified from the study site included Heterolepaspp., Textulariaspp., Quinqueloculinaspp.,Operculina spp. Pseudorotaliaspp., Amphisteginaspp., Cylindroclavulinaspp., Elphidiumspp., Ammobaculitesspp., Asterorotaliaspp. and Bolivinaspp.. The common genera found in the sediments of the study areas were Heterolepa, Textularia, Quincoloculina, Operculinaand Pseudorotalia. The highest and lowest values of Fisher alpha and Shannon-Wiener indices were shown at Station C287 and Station B482 respectively. The highest value of Fisher alpha was 3.23 and the lowest value was 1.97. The highest and lowest values of Shannon-Wiener were 2.30 and 1.91. The highest index value of diversity was 3.23 at depth 67.76 m and the lowest value was 1.53 at depth 45.54 m and 68.45 m. From this study, depth is not the main factor that influencesthe diversity of benthic foraminiferal in northwestern Sarawak waters.
Keusahawanan sering dianggap sebagai subjek yang lebih cenderung kepada pelajar dalam bidang perniagaan tetapi tidak untuk pelajar yang mempunyai pelbagai kemahiran yang terlibat dalam bidang teknikal. Namun, ini adalah satu tanggapan yang tidak seharusnya wujud kerana Malaysia seharusnya perlu mengenal pasti kesedaran keusahawanan dalam bidang teknikal. Pada masa kini, kesedaran keusahawanan dalam bidang teknikal tertentu adalah kurang lantaran program keusahawanan lazimnya lebih tertumpu kepada pelajar InstitusiPengajian Tinggi (IPT). Misalnya, Pembangunan Keusahawanan Bumiputera adalah lebih tertumpu kepada golongan siswazah IPT, belia dan wanita. Dasar Pembangunan Keusahawanan IPT juga diperkenalkan agar modal insan dengan daya pemikiran, atribut dan nilai keusahawanan dalam kalangan IPT tempatan dapat dilahirkan. Tujuan kajian ini dijalankan adalah untuk mengenal pasti tahap kesedaran keusahawanan dalam kalangan pelajar Institut Latihan Perindustrian (ILP) di Terengganu berhubung dengan faktor keusahawanan dari aspek individu usahawan yang berbeza serta struktur dan persekitaran perniagaan. Seterusnya, mengkaji hubungan antara kesedaran keusahawanan dengan pembolehubah tidak bersandar lain yang berkait dengan kajian seperti ciri keusahawanan dan cabaran keusahawanan. Kaedah kuantitatif telah digunakan dan borang soal selidik diedarkan kepada 280 orang pelajar. Hasil analisis regresi berganda menunjukkan bahawa cabaran keusahawanan merangkumi sikap dan minat, kemahiran keusahawanan serta pendidikan dan pengetahuan keusahawanan merupakan elemen paling signifikan yang mempengaruhi kesedaran keusahawanan dalam kalangan pelajar berkemahiran diILP untuk menjadi seorang usahawan. Oleh itu, adalah sangat penting bagi kerajaan Malaysiauntuk memberi perhatian terhadap cabaran yang dihadapi oleh para pelajar ini dan mengambil tindakan terhadap segala kemungkinan yang boleh mempengaruhi atau memberi kesan kepada minat pelajar terhadap keusahawanan pada masa akan datang.
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
This study examined the relationship between body dissatisfaction and eating disorder of undergraduate students in University Malaysia Terengganu (UMT). Using stratified random sampling technique, data from 299 respondents was gathered. Body dissatisfaction was measured using Body Shape Questionnaire while eating disorders were assessed using Eating Attitudes Test. Descriptive statistics showed thatthe majority of the respondents reported no symptom of body dissatisfaction. With regard to eating disorders, respondents reported low levels of dieting, bulimia and oral control, indicating that an eating disorder in this sample was somewhat low. T-test analyses showed that there were no significant gender differences in body dissatisfaction as well as in eating disorders. However, there was evidence to suggest that female respondents had slightly higher level of eating disorder than males. Results of Pearsoncorrelations showed there was significant relationship between body dissatisfaction and total score of eating disorders, dieting, bulimia and oral control subtypes (r = .58, p
Studies on fungal taxonomy and fungal diversity are crucial for a better understanding of the interactions between fungi and their habitats. To date, there is no published record on macrofungal diversity in Pulau Bidong, Terengganu. Therefore, this study aimed to identify macrofungi species found with their respective substrates and to determine the macrofungal diversity in the island. The study was conducted at two different occasions and comprised of two trails near Universiti Malaysia Terengganu Research Station in Pulau Bidong, Terengganu. Collectionof fresh macrofungi was made and additional data including host information, distinctive features of each fungal sample and several environmental parameters was also recorded. Fresh specimens were later observed and identified before being dried prior to storage. Overall, 65 macrofungal species with 2 unidentified species belonging to 21 families and 34 genera were recorded. Trail A and trail B recorded diversity index of2.67 and 3.14 for Shannon Index while Simpson index recorded 0.90 and 0.94 respectively. The macrofungal diversity was dominated by family Polyporaceae while rare species discovered were from family of Tricholomataceae, Hericiaceae, Stereaceae, Schizophyllaceae, Sclerodermataceae, Dacrymycetaceae, Tremellaceae, Russulaceae and Clavulinaceae. The most common macrofungal substrates was decayed branches while other macrofungal substrates found were decayed trunks and leaves, soil,termite mounds, and living tree. In conclusion, the macrofungal species were randomlydistributed with high diversity in both trails. Therefore, it is recommended that anincrease in sampling trips, sampling efforts and areas covered be provided to increase the number of macrofungal species discovered and accuracy of diversity studies in the future.
Penggunaan media sosial tanpa budaya civik dan nilai etika dalam kalangan pelajar telah menjerumuskan ramai pelajar IPTA dalam kancah buli siber. Buli secara maya boleh dilakukan dalam muatnaik perkataan kejam, gambar dan video mangsa bagi menguggut, menghasut, fitnah, membalas dendam sehingga pemangsa merasakan dirinya hebat dan berkuasa. Durasi pantas semua maklumat boleh disebarluaskan dalam kadar pantas dengan jangkauan seluas dunia. Antara faktor buli siber berlaku dalam awal dewasa ialah cemburu, menanggih perhatian kawan media sosial, kapasiti ‘jaguh” atau gengster dalam media sosial. Kajian terdahulu lebih mefokuskan kepada fenomena buli dalam kalangan remaja, pelajar sekolah dan pengguna media massa. Manakala, amat kurang kajian berkaitan isu buli siber dalam kalangan mahawiswa. Objektif utama kajian ini ialah meneroka impak buli siber dalam kalangan pelajar UKM. Pendekatan kajian kes digunakan sebagai rekabentuk metodologi kajian ini. Pembinaan garis panduan soalan semi-struktur digunakan untuk temu bual responden. Seramai 6 orang responden telah dipilih bagi kajian ini dengan menggunakan teknik persampelan bertujuan (purposive sampling). Lokasi kajian yang dipilih ialah Universiti Kebangsaan Malaysia.

Implikasi kajian ini diharapkan dapat mencadangkan program intervensi dan advokasi yang sesuai kepada pekerja sosial dalam mengendalikan kes buli siber di Bahagian Kaunseling Siswa, UKM.
utan Lipur Jeram Linang in Kelantan was carried out within 0.1 ha plot. All vascular plants (except lianas and epiphytes) were enumerated and identified. A total of 255 taxa representing 121 species belonging to 87 genera in 47 families were identified. Among these were 24 species endemic to Peninsular Malaysia and 47 species with medicinal values. Plants were categorized according to growth forms as follows: 67% trees, 17% shrubs, 7% palms, 6% herbs, and 3% ferns. Based on Important value index (IVI), Elateriospermum tapos, Goniothalamus umbrosus, and Monocarpia marginalis were the most dominant species whilst Rubiaceae, Arecaceae and Fabaceae were the three most diverse families. Species diversity was high based on the Shannon-Weiner index with the value of 4.38. In this study, two species from Dipterocarpaceae, which were Dipterocarpus grandiflorus and Shorea collina, were listed as Endangered (E) and Critically Endangered (CE) species respectively according to IUCN Red List. Information gained from this study showed that the forest harbored high plant diversity and endemism, so proper management is needed to protect and conserve this forest for sustainability and development.
The household activities such as vacuuming may elevate the concentration of particulate matter in indoor environments. Cleaning workers and occupants inside closed room may be exposed to the fine particulate matter and at risk of developing numerous respiratory symptoms. This study aims to determine the concentration of the particulate matter (PM10 and PM2.5) that might arise during vacuuming activities and estimated the surface compartmental residence time of particulate matter in indoor environment after each vacuuming activities. The PM10 and PM2.5 concentrations throughout vacuuming were measured in forty-seven offices in Universiti Malaysia Terengganu using the TSI Dust Track DRX. Based on the concentrations measured, the surface compartmental residence time was then estimated using standardized equations taken from literature. The result shows that highest particulate matter concentration was nearly eleven times higher than the World Health Organization guidelines of 25 µg/m3 for PM2.5 concentration (PM2.5 was 270 µg/m3, PM10 was 421 µg/m3), while the particulate matter were estimated to remain lingers inside the air for around 1-4 days before being deposited on the surface. In conclusion, the usage of vacuum cleaners may contribute to more particulate matter being released inside the air due to the resuspension phenomenon. Therefore, it is important for the occupants to maintain proper ventilation after each vacuuming activities took place.
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.
The concentrations of airborne particulate matter (PM) is often measured as a mass concentration. However, the other way to express particulate matter is by using the Particle Number Count ([PNC]) concentrations. This study aims to analyse the seasonal variation of airborne particulate matter in terms of [PNC] by using R packages and the Boosted Regression Trees (BRTs) technique. The study was conducted at IOES, Universiti of Malaya in Bachok, Kelantan. The monitoring was important to understand the variability of seasonal effects due to different seasons. In this work, only the datasets for three seasons (Inter Monsoon, North East Monsoon and South-West Monsoon) were analysed involving 25,958 data. The air quality monitoring equipment involved was the particle counter Environment Dust Monitor GRIMM Model 180 and a weather station for recording the meteorological parameters. The data analysis was completed by using R software and its package for evaluating seasonal variability and providing the statistical analysis. The relationship between variables was studied by using the Boosted Regression Tree (BRT) technique. The interaction between independent variables towards the [PNC] in different seasons was discussed. The best setting result of BRT model evaluation R² is 0.22 (North-East Monsoon), 0.87 (Intern monsoon 1), and 0.59 for South West Monsoon which indicated that the model developed is acceptable except for NEM and intern monsoon seasons. Temperature (57 %) and wind direction (67%) were found to be the highest factor influenced by the formation of [PNC] concentrations in this area. Finally, good results indicated that BRT technique is an acceptable way to analysed air pollution data.
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.
Synthesis of nanoparticles by using plant have sparked interest among researchers due to environmentally safe, inexpensive and simple method to compare with chemical method. Use of plant in synthesis zinc oxide nanoparticles (ZnO NPs) that act as reducing and capping agent are more recommended, due to high production of product and rate of synthesis is faster than using microorganism. This study focus on the synthesis of ZnO NPs by using leaf extract of aloe vera (Aloe bardenisis miller) with different concentration (30%, 40% and 50%) and various calcination temperature which are 500 ˚C, 700 ˚C and 900 ˚C for 4 hours. Fourier – transform infrared spectroscopy (FTIR), Thermogravimetric Analysis (TGA), scanning electron microscopy (SEM), X-ray Diffraction (XRD) and Brunauer-Emmet and Teller (BET) were used to characterize the prepared samples. FTIR spectra showed present wavenumber in between 400-500 cm-1 indicated the presence of Zn-O stretch. Powder XRD pattern confirmed the hexagonal wurtzite structure with average particles size from 24.19 nm to 67.69 nm for all concentration and temperature by using Scherer’s equation. For SEM analysis the images show irregular shape for concentrations 30% and 50% with size range from 500 nm to 900 nm while for concentration 40% cubic shape was observe with size range from 140 nm to 900 nm. All characterize show that formation of ZnO NPs depend on the concentration and calcination temperature. Sample 30% and 50% ZnO NPs was applied in lithium battery at voltage from 0.01 to 3. 1.2 mAhg-1 was recorded for sample 30% ZnO NPs while 100 mAhg-1.
