COURSE ALLOCATION AMONG LECTURERS USING PYTHON
No full textCourse allocation among lecturers describes the process of allotting a set of courses to a number of lecturers. The administrators who are responsible in the allotment of courses to lecturers at least once a year are supposed to assign the most suitable lecturer to teach the courses in an efficient and effective way. However, the process of course allocation among lecturers is being done manually in most of the educational institutions through a trial-and-error manner and the lecturers’ years of teaching experience was not being considered during the allocation causing imprecision of the allocation made. Therefore, a random allocation of courses to lecturers using Microsoft Excel was done and the objective function of the solution obtained through the random allocation is compared to the objective functions of exact solutions obtained using OpenSolver and Python. The purpose of using Python is to automate the allocation of courses to lecturers in which a lecturer’s years of teaching experience is being optimized even if there is occurrence of data changes. Besides that, the computational time used in obtaining the solutions using the three mentioned approaches are compared to show the difference in terms of efficiency and effectiveness of the allocation made. Python proved to be the most efficient and effective approach as compared to the other two approaches used for this course allocation problem as Python requires the least time and effort to obtain the optimal combination of lecturers and courses based on lecturers’ years of experience
PREPARATION AND CHARACTERIZATION OF MAGNESIUM/ALUMINIUM LAYERED DOUBLE HYDROXIDE AS FILLER IN LOW-DENSITY POLYETHYLENE COMPOSITE
No full textPolymer had been widely used in industries nowadays. However, the properties of the polymer itself are limited to a particular application. This study describes synthetic clay, layered double hydroxide (LDH), as a filler in low-density polyethylene (LDPE) composite. LDHs of magnesium/aluminium-dodecyl sulfate (Mg/Al-DS) and its grafted with triethoxymethylsilane (TEMS), (TEMS-g-Mg/Al-DS) were synthesized through co-precipitation and salinization reaction methods. The presence of alkyl group, v(C-H) in both LDH had confirmed through Fourier transform infrared (FTIR). The appearance of peaks in FTIR spectra within the absorbance range of 2800 – 2930 cm-1 indicates a successful surface modification of LDH, supported by the changes of interlayer spacing and the presence of carbon from X-ray diffractogram and CHNS elemental analysis, respectively. The synthesized LDH was mixed with LDPE via melt intercalation method. The LDH modification resulted in higher interaction and compatibility between the LDPE matrix and LDH by the formation exfoliated type of nanocomposites, as suggested by XRD analysis

In Malaysia, there are very small amount who made this research. The finding of this study showed that majority respondents are at normal level for mobile phone use. Pearson correlation result shows there was significant correlation between mobile phone use with an anxiety among students. This study indicates the important mobile phone use toward an anxiety among university students
DISCOVERING FACTORS THAT AFFECT IGEN ACADEMIC PERFORMANCE IN THE UNIVERSITY
No full textThe advancement of technology in digital revolution such as Internet of Things has gained attention in all over the world. This myriad of technology innovations affects all aspects of the human lives today. The generation who has grown up during this era, known as the iGens, mostly relies on the technology in every aspect of their lives, including education. Thus, technology also gives profound impact in educational transformation nowadays to convey innovative education. However, lack of innovation in education becomes a challenge to meet this demand. Therefore, this study was carried out with the aim to discover factors which may affect academic performance of the iGen students in the university. A total of 250 self-administered questionnaires were distributed to the accounting students at UMT with a response rate of 93.6% (234). Using multiple regression analysis, the findings showed that parental involvement and student’s attitude contribute more towards academic performance of iGen students rather than the technology itself. This finding showed that human factor such as support from their parents and individual factor are vital towards their academic performance regardless of from technology savvy generation or not

BENTHIC COMMUNITY DIVERSITY AT MARINE ARCHAEOLOGICAL SITE, PULAU BIDONG, SOUTH CHINA SEA
No full textAn artificial structure on the seafloor will affect the structure of the benthic community. This structure may include a sunken ship or a century-old building that becomes an underwater heritage site. Benthic communities at underwater archaeological sites have been studied around the world, though it is lacking in Malaysia. This study aimed to determine the benthic community composition and diversity in sediment and on an artifact (small ceramic pot) at the marine “Bidong shipwreck” archaeological site. SCUBA divers collected samples (sediment and artifact) from an 18 m depth archaeological site in October 2017. Then, all samples were fixed with 10% buffered formalin and preserved in 80% ethanol prior to identification analysis. Most benthic organisms were identified until class taxon, except for class Polychaeta until family. A total of 2711 benthic organisms which belonged to eight phyla, and 17 classes were recorded, of which 638 are polychaetes. In the archaeological site, Syllidae was the most abundant family in the sediment, and the family Nereididae dominated in artifact while Capitellidae was dominant at the control site. Shannon-Weiner diversity index showed variation and ranged from 1.5 to 2.1, while the evenness index value ranged from 0.56 to 0.77. The benthic community in sediment on both sites were more diverse and even compared to the artifact. Simultaneously, Jaccard’s similarity test discovered that the benthic community’s composition in sediment at the control site was highly similar to the archaeological site (0.80) comparatively to the artifact (0.65). It is suggested that the benthic community at the archaeological site has reached an equilibrium state similar to the control site. The scouring process may influence the lower benthic community composition on the artifact than sediments in its surroundings. These findings provide an overview of benthic community’s post-disturbance resilience and reveal a marine archaeological site’s ecological status
POSITION ACCURACY STUDY OF USING PORTABLE USB GPS ANTENNA IN OPEN AND CLOSED SPACES
No full textThis research involved the positional accuracy study of portable Global Positioning System (GPS) in open and closed spaces. The project has several phases; the first phase consists of setting the portable GPS antenna on the laptop computer and running the u-center data recording application software for raw data recording. The second phase involves data filtration, extraction of position information both for open and closed spaces for analysis. The next stage generation of results including the determining means of latitude and longitude errors and comparing positional accuracy in open and closed spaces. The errors between positions in open and closed spaces were determined for comparison based on selected known locations. The results are plotted into real latitude and longitude scale to show the position acquired. The result in open and closed spaces were finally statistically compared. The pattern of positions accuracy for open and closed space indicates larger longitude error compared to latitude error varying between 1-15 meters in terms of range error from the mean. Test for known positions using ANOVA indicate significant difference between locations acquired in open and closed spaces
THE EFFECTS OF LIGHT-EMITTING DIODES (LED) IRRADIATION TREATMENT ON THE POSTHARVEST PRESERVATION AND MICROBIOLOGICAL QUALITY OF STRAWBERRY (Fragaria ananassa) CV. FESTIVAL
No full textStrawberry (Fragaria Ananassa sp.) is non-climacteric, aggregate fruit with a rich source of anthocyanin and vitamin C. However, strawberry has short storage life and is very susceptible to decay and physiological deterioration process. Therefore, emitting the post-harvest LED light to strawberries during cold storage has been studied. This work aimed to evaluate different LED light treatment effects to retain post-harvest quality and microbial quality of the strawberry. The post-harvest parameters that have been used are weight loss, colour, firmness, total soluble solids, titratable acidity, and pH. The microbial parameter such as Escherichia coli count, Salmonella count, total plate count, and mold count would also has been assessed. Strawberries were irradiated under three different LED light types (white, blue and red). Blue and red LED lights have different wavelengths, which are 470 nm and 630 nm. The strawberry fruits were stored at 5ºC in a cold room and study parameter were assessed in 10 days. There were statistically significant differences (p<0.05) between the treatment of weight loss, firmness, pH, and total soluble solid. The best treatment for this experiment is blue LED light which showed the lowest weight loss, retained the colour and delayed firmness loss of the strawberry. This study also proved that blue LED light could reduce the growth of E.coli. In conclusion, LED light produces minimal heat, which improves food safety and preserves post-harvest quality of strawberry
RAINFALL FORECASTING WITH TIME SERIES MODEL IN ALOR SETAR, KEDAH
No full textThe prediction of rainfall on monthly and seasonal time scales is not only scientifically challenging but is also important for planning and devising agricultural strategies. In this paper, the study is conducted to examine the pattern of monthly rainfall in Alor Setar, Kedah within ten years which is from 2008 to 2018. This paper considered a model based on real data that obtained from Department of Meteorology Malaysia. This study indicates that the monthly rainfall in Alor Setar has a seasonal and trend pattern based on yt vs t plotting, autocorrelation function and Kruskal Wallis Test for seasonality. The examined rainfall time-series modelling approaches include Naïve Model, Decomposition Method, Holt-Winter’s and Box-Jenkins ARIMA. Multiplicative Decomposition Method was identified as the best model to forecast rainfall for the year of 2019 by analysing the previous ten-year’s data (2008-2018). As a result from the forecast of 2019, October is the wettest month with highest forecasted rainfall of 276.15mm while the driest month is in February with lowest forecasted rainfall of 50.55mm. The model is therefore adequate and appropriate to forecast future monthly rainfall values in the catchment which can help farmers to plan their farming activities ahead of time
STUDY OF LOCAL TOURIST SATISFACTION IN A RURAL DESTINATION AT MOUNT MULU NATIONAL PARK IN MIRI, SARAWAK
No full textTourism 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
