    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.

    Clean, safe and readily available water is very crucial in everyday life, especially for health, hygiene, and the productivity of the community. Unfortunately, increase in contaminants in water supplies from human activities and industrialization is very worrying. Conventional wastewater treatment includes the usage of alum that will affect health with prolonged consumption. This research was carried out to focus on the development of wastewater treatment system using adsorbent from Moringa oleifera seeds. Adsorbent was successfully synthesized from the seeds of Moringa oleifera. Characterization of the sample was made using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM), while the effectiveness of water treatment was analyzed using Turbidity Meter. Then, all samples were tested against kaolin wastewater. XRD results showed that all the adsorbent samples were amorphous in nature. FTIR results indicated that there were hydroxyl group and carboxylic group in the sample representing numerous oxygen-riddled functional groups on the surface. From SEM results, it was clearly shown that the pore structure and size of Moringa oleifera affected the capability of adsorption where the smaller the size, the more effective the sample. Turbidity test showed that the sample that worked best for wastewater treatment was adsorbent from Moringa oleifera seeds in size of 125µm that was heated for 4 hours with 93.76% turbidity removal. Therefore, this study proved that the adsorbent from Moringa oleifera seeds is very suitable for high turbidity wastewater treatment. Further studies investigating the combination of conventional activated carbon with adsorbent from Moringa oleifera seeds should be conducted before these samples are made available for further use so that we can compare which sample works best for wastewater treatment.

    Methyl orange is one of the anionic dyes and is a major pollutant from textile industry that enters both aquatic and atmospheric systems. In this research, methyl orange was degraded using TiO2 powder and immobilized TiO2 on glass. Titanium tetra-isopropoxide (TTIP) was used for preparation of TiO2 powder using soft chemistry method, and it was immobilized on glass via paste-gel coating method. The prepared photocatalysts were characterized by XRD and SEM. Highly crystalline anatase TiO2 powder photocatalyst was obtained. Meanwhile, immobilized TiO2 was less crystalline and agglomerated onto the glass surface. TiO2 powder had higher degradation rate (71%) compared to immobilized TiO2 (52%) due to its chemical stability and larger amount of photocatalyst contacted with methyl orange during the degradation process.

    This study was conducted to determine the morphology, prevalence and mean intensity of monogeneans on gill filaments of striped catfish Pangasianodon hypophthalmus (Pangasiidae).P. hypophthalmus are important economic fish in Southeast Asia region and predominantly produced in Asian countries such as Malaysia, Bangladesh, Indonesia, Vietnam, Laos, China and Cambodia through aquaculture. Thirty fish were sampled from an earthen pond located in Kuala Besut, Terengganu, in the period from January to February, 2018. The monogenean parasites were removed from the gill filaments and counted. For the morphological study, the extracted monogeneanswere mounted on a slide by using drop of ammonium picrate-glycerin (APG) and then were observed under the Compound Advanced Research Microscope. The drawing was done with the aid of lucida camera attached to compound microscope. The monogenean parasite was identified as Thaparocleidussp based on the characteristics of the morphology and morphometrics of the parasite, which did not differ significantly from the previous descriptions of the same species discovered in other geographic locations. The prevalence and mean intensity levels were 100% and 106.07 parasites per fish, respectively. The monogenean parasites discovered throughout this examination were recorded and the data obtained was summarized.

    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.

    DNA Barcoding, primarily focusing on cytochrome coxidase subunit I (COI) gene has been appraised as an effective tool for species identification. Nonetheless, species identification based on molecular approach is essential for discrimination of look-alike species. In this study, we focused on the marine fishes Family Nemipteridae, one of the commercially important group distributed within the surrounding seas of Malaysia. Some of the samples were collected during the National Demersal Trawl Survey in the Exclusive Economic Zone of East Coast Peninsular Malaysia by the Department of Fishery Malaysia. A 652bp region of COI was sequenced for 74 individuals from nine putative species. Additional 34 COIsequences from GenBank were also included in this study making the total number of samples analysed to 108 individuals. The averageKimura 2-parameter (K2P) nucleotide divergence was 0.34% among individuals within species and 6.97% within genera. All putative species formed monophyletic clades in both Neighbour-joining (NJ) and Maximum-likelihood (ML) trees. However, there was a potential misidentification in specimen identified as Nemipterus tambuloides,as the specimen did not group with their own taxa. It was genetically grouped in Nemipterus thosaporni clade. This study supports the effectiveness of COIgene in species discrimination of Family Nemipteridae.

    This study was carried out in Marang, Terengganu. The objective of this study is to analyse the socio-economicprofileof fishermen and their monthly income. The Slovin’s formula was used to calculate thenumber ofrespondentsin Marang and the data was collected through a survey involving 50 respondents consisting of Malay fishermen. The results of the study showedthat the dominant types of fishing gear used were hooks and lines, gillnets and purse seines. The socio-economic profile showedthat a majority of the fishermen (35%) were aged between 40-49years, 36% of the fishermen had between 10-19 yearsof experience, and 55% of the fishermen hadbetween 2-5 children. The average monthly income of the fishermen was MYR1853.49 for those using hooks and lines, MYR2105.09 for gillnets and MYR2595.39 for purse seines. It appears that the use of purse seinesgenerated the highest income for the fishermen. Generally, the income was not fixed as it depended on the amount of catch for each fisherman’s trip, which was also affected by the season.

    The emergence of mega vessels is not a new event in container shipping industry. Containerization has caused a spectacular growth in maritime transportation and brought significant developments to the industry, ranging from operation systems to seaport infrastructure expansion. Container vessels have gotten larger, with some having the capacity of 18,000 TEUs (Triple E Class), to cope with the demand for economies of scale (EOS). Mega vessels can influence the strategic planning of seaport operators for massive infrastructure development and investment on existing terminals at the seaports. The objective ofthis research is to identify and measure the requirements for seaport expansion that need to be prioritized by seaport operators to accommodate mega vessels. Additionally, this research aims to determine the challenges faced by seaport operator to meet the seaport infrastructure expansion requirements. Two mathematical methods were employed, namely Analytical Hierarchy Process (AHP) and Evidential Reasoning (ER). The results showed that the most important requirement for seaport expansion is navigation aspect followed by berth expansion, terminal, yard and gate operations. This research is expected to assist seaport operator in making a decision on prioritizing t requirements for expansion. Furthermore, this research aims to measure the readiness of seaports to serve mega vessels in global shipping industry in order to achieve competitive advantages.

    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.

    This study focused on feasibility analysis of hybrid electrification system for an aqua-tourism resort located remotely from the grid connection in Terengganu. There were four standalone systems used in this study: diesel/PV/biomass/battery, diesel/PV/battery, biomass/diesel/battery, and diesel only. The design and analysis of these systems were done using Hybrid Optimization of MultipleEnergy Resources (HOMER) software. The results showed that the diesel/PV/battery system was the optimum solution in terms of net present cost (NPC) and cost of energy (COE). This system comprises 20 % of PV penetration with NPC and COE of USD 57,823 (RM 241, 729.90) and 0.428 USD/kWh (1.79 RM/kWh), respectively. Meanwhile, the diesel/PV/biomass/battery system with NPC of USD 65,388 (RM 273, 355.49) and COE of 0.484 USD/kWh (2.02 RM/kWh) was found to be the best among all systems in terms of greenhouse emissions. This system was able to reduce almost 70 % of carbon dioxide if compared with diesel only system and about 15 % lower than the diesel/PV/battery system with a renewable energy fraction of 44 %.

    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.

    In general, the nature of gold that acts as a hedge against inflation and its stable price over the course of the financial crisis has made it a unique commodity. Priceforecasts are a must for gold producers, investors and central bank to know the current trends in gold prices. Forecasting the future value of a variableis often done with time series analysis method. This study was conducted to determine the best model for forecasting gold commodity prices as well as forecasting world gold commodity prices in 2018 using Box-Jenkins approach. The data used in this study wasobtained from Investing.Com from 2015 until 2017. Thisstudy shows that ARIMA (1,1,1) is the best model to predict gold commodity prices based on Mean Absolute Percentage Error (MAPE). MAPE value for ARIMA (1,1,1) is 0.02%, where this value proves that forecasting using ARIMA (1,1,1) is the best forecasting becauseMAPE value is less than 10%.

    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.

    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.

    Pineapple is one of the most important commercial fruit crops served in fresh-cut form which is convenientfor the consumers. However, fresh-cut pineapple induces the activity of phenolic compounds which triggers the generation of brown or dark pigments. Browning incidence (BI) directly influences the fruit’s acceptability and marketability. Therefore, different exposure times (5mins, 10mins, 15mins and 20mins)and typesof LED lights (white, red and blue) were applied on fresh-cut pineapple stored at 5oC storage for twelve days to reduce BI. A significant interaction between the two factors was recorded in lightness coefficient, chroma, total phenolic and ascorbic acid (AA)contents. Regardless of exposure times, all types of LED lights, mainly the blue light, succeeded in delaying BI in fresh-cut pineapple. In conclusion, blue light had a tendency todelay BI andmaintaintheother postharvest quality attributes of fresh-cut pineapple.
