Abstract

Assessing the quality of learning in higher education is one of the efforts to ensure its standards. Typically, the assessment of the quality of learning implementation involves observation by multiple raters. This study aims to provide construct validity evidence and estimate the reliability of performance assessment instruments for educators in higher education. 225 second-year and third-year students from the Faculty of Education participated as raters, evaluating the performance of educators in their teaching practices. Forty assessment items were used to evaluate the performance of 19 instructors. Exploratory Factor Analysis (EFA) and Generalizability Theory (G-Theory) were employed to examine the quality of the performance assessment instruments. The EFA analysis resulted in the identification of five factors that contribute to educators' performance in teaching: (1) readiness and planning, (2) pedagogy and professionalism, (3) personality, (4) social relationships within the classroom, and (5) social relationships beyond the classroom, collectively explaining 67.671% of the variance. Of the 40 assessment items, 37 demonstrated construct validity, while three required revisions. These findings indicate the alignment between the instrument's factors and the formulated theory of teaching competence. The reliability of the measurements was estimated using G-Theory in RStudio, yielding a relative G coefficient of 0.88 for three raters. The D-Study results indicated that the instrument could be used to assess performance, with an estimated generalizability coefficient of 0.738, requiring a minimum of five raters for each person (educator) being evaluated. We recommend employing G-Study and D-Study to determine the number of raters involved in performance assessment as a means of cost and time efficiency in the evaluation process.

Abstract

Fruit flies are plant-disturbing insects that harm farmers both qualitatively and quantitatively. Initial symptoms of damage to host plants are marked by the appearance of black spots until the plant parts rot and fall. Fruit flies will inject their eggs until they hatch and become larvae, then the larvae will gnaw the fruit flesh from the inside. Control of fruit flies so far still uses factory chemical insecticides that are not environmentally friendly and leave residues that threaten health. Controlling fruit flies that are environmentally friendly and not at risk of leaving residue can use attractants made from natural ingredients. This study was aimed to determine the effectiveness of the use of natural-based attractants that utilize local raw materials on the allure of fruit fly insects. The materials used in this study were clove leaves, lemongrass leaves, guava leaves, pandan leaves, lime leaves, pineapple and star fruit. The tools used to trap insects use two tools, namely trap bottles and glue. The results showed that the use of lemongrass leaves, clove leaves, guava leaves and pineapple fruit was quite effective in trapping fruit fly pests. Lemongrass leaves more effective than others (27 results in a week). A more effective tool to use is fly glue. The most effective combination is glue with clove leaves, guava leaves, and pineapple (number of results is >100 in a week).

Abstract

The integration of information and communications technology in teaching and learning is growing at an exponential rate due to many factors we have observed lately, such as the outbreak of COVID-19. The unprecedented outbreak of COVID-19 took the world by surprise. Many sectors such as health and education were left shattered due to the outbreak of COVID-19. The outbreak compelled the educational sector to come up with alternative majors to keep the teaching and learning process alive as the physical classes were suspended as means to curb the spread of COVID-19. In an attempt to investigate different ways Engineering Graphics and Design teachers used to conduct lessons during the COVID-19 lockdown, this study employed a qualitative approach. Data was collected through semi-structured interviews and analysed using thematic analysis. The findings of this study indicate that COVID-19 did influence the way teachers are teaching post-COVID-19.  The study findings further reveal that WhatsApp was the tool most teachers relied on to keep teaching and learning alive, however, some teachers were experiencing problems. The study recommends that teachers should continue using WhatsApp as a way of extending lessons during home hours.

Abstract

Biofuels like biodiesel and bioethanol are the latest technologies to meet the rising energy demand and to replace depleting petroleum supplies. Biodiesel, which is made from vegetable oils, can be used to replace diesel fuel. Vegetable oils are a sustainable energy resource with a similar energy content to diesel fuel. In the proposed process, the main product from the reaction is biodiesel, whereas the by-products consist of glycerol and fertilizer. Biodiesel is mainly used in automotive diesel engines for various reasons, such as having a greater oxygen content, a higher cetane number, a higher viscosity, a lower aromatic content, and very little sulfur. These properties are essential in engine performance, combustion, and emissions. This review provides a comprehensive analysis of recent literature on biodiesel production methods from waste cooking oil, where the methods are grouped systematically and assessed. A decision table on process selection is provided to screen the most suitable technology for biodiesel production from waste cooking oil. The properties and application of potential products and by-products are also discussed. Finally, the case study of supplying biodiesel for B5 fuel in Brunei Darussalam is also provided.

Abstract

Natural organic matter (NOM) seriously challenges the drinking water supply. It typically exists as complex organic substances generated in the natural water ecosystem as part of hydrologic, biological, and geological cycles. The significant variation, composition, and abundance of NOM in natural water or wastewater necessitate the implementation of robust and adaptive technologies, particularly in addressing even more stringent standards of drinking water supply or treated water discharge. Coagulation is one of the most common processes for water and wastewater treatments. It is highly desirable to treat feed containing NOM because it prevents the disinfection of by-products formation. Therefore, current dynamics of NOM in terms of varying compositions and concentrations demand improvement in handling the coagulation process through optimization of operational parameters (dosing and the control of pH), application of novel and more effective coagulants, and as a combination with other processes through process intensification. This review provides a comprehensive analysis of recent literature on developments of coagulation for NOM removal. The coagulants are grouped systematically and assessed. Next, enhanced coagulation via process intensification with other processes (membrane filtration, oxidation, adsorption, and ion exchange) is discussed. Lastly, the future outlook on research direction on sustainable coagulation process is listed to support circular and bioeconomy.
