Abstract

LaNi5 is widely used in various applications. Many methods to produce LaNi5 particles have been reported but information for the large-scale production, so far, is less available. This study aimed to evaluate the project for the production of LaNi5 particles using combustion-reduction (CR) and co-precipitation-reduction (CPR) methods based on engineering and economic perspective. Engineering evaluation was conducted by evaluating the CR and CPR processes from stoichiometry. For the economic evaluation, several economic parameters were calculated in the ideal condition including gross profit margin (GPM), payback period (PBP), break-even point (BEP), cumulative net present value (CNPV), profitability index (PI), internal rate return (IRR), and return on investment (ROI). For the worst cases in the project, it was done by calculating both the internal problems (i.e., raw materials, sales, utility, labor, employee, fixed cost, variable cost, and production capacity) and the external issues (i.e., taxes and subsidiaries). The engineering analysis provided the information that CR and CPR projects are prospective for being able to be done using commercial apparatuses. The economic analysis from GPM, PBP, BEP, CNPV, and PI showed the positive results, while IRR and ROI showed the negative ones, indicating that the projects are acceptable for large-scale production, but it seems to be less attractive for industrial investors. The analysis also confirmed that the CR process was more prospective than the CPR process. This work has demonstrated the important of the projects for further developments.

Abstract

The purpose of this study was to review barriers in the foreign workers in Industry. We took data for the industry in Malaysia. This study was conducted based on only 55 workers from the Nadayu site. It is recommended that the study be carried out in a larger sample and involvement of the Construction Industry Development Board (CIDB) and the registered CIDB contractor. This study focus on the language barrier, safety knowledge, and background of workers, and these factors contribute to the effectiveness of training. It is proposed to have an in-depth study on the syllabus, methodology of training, motivation, and commitment of the company to improve CIDB training.

Abstract

The objective of this study was to show the correlation between construction, safety, accident, and the effectiveness Construction Industry Development Board (CIDB) Green Card Training Program. This paper was based on a literature review to get an explanation. This study can be used for reference for informing the need in taking care of possible risks and safety in the industry.

Abstract

This paper focused on the impact of the Construction Industry Development Board (CIDB) Training Green Card Training program based on the general worker’s knowledge, behavior, and safety performance at the Nadayu site and also discovered the primary factors affecting CIDB Green Card Training Program. For this purpose, 55 workers filled up the questionnaire before and after attending the safety training. The effectiveness of the workers can be determined through the knowledge acquired from the training and can be evaluated from their behavior through observation by management personnel at the site. On top of that, the performance of safety at the site can be evaluated through the numbers of NCR, Memos, Penalties, and first aid. The results show that language and the background of participants were found to be the strongest factor that is affecting CIDB Green Card Training Program. Basic safety knowledge of participants has also increased after attending the training and improvement based on workers' behavior at the site were observed as well. Improvements need to be considered to enhance the CIDB Green Card Training program by providing training in the native language, screening the workers who have experience in the construction line in Malaysia, implementing various methods of teaching, presenting updated slide presentations, and evaluating participants to test their understanding.

Abstract

This study aims to identify the challenges faced by undergraduate students with remote e-assessments during Covid-19 outbreaks. The study was guided by the following specific objectives: to identify the level of students’ challenges to remote e-assessments in four major areas which are internet connectivity, academic integrity, disturbance in-home learning, and overflow of assignments, to identify significant differences between student’s location and family income category with four major areas of challenges to remote e-assessments. To achieve the objectives, students from one of the undergraduate programs at University Teknologi Malaysia have been chosen as the sample size. This study was designed to follow a single approach which is quantitative methods by means questionnaire surveys were distributed among the students and the data gathered was analyzed using SPSS software. The results from the analysis indicated that students facing the highest level of challenges to remote e-assessments during Covid-19 outbreaks are the overflow of assignments. The result from the study also showed that there is a significant difference between students’ family income and four major challenges to remote e-assessments. The recommendations are that organizations, especially at the university level should try to give great emphasis on e-assessments activities to develop those smooth practices to a great extent since the practice may eventually replace the traditional examination.

Abstract

Implementing remedial and enrichment strategies followed by modeling the weight of the appraisal is the goal to be achieved in this study. The ASSURE model in this study has been used to develop an appraisal model for remedial and enrichment activities integrated with the independent curriculum in the vocational field. The results showed that the peer tutoring strategy among students could optimize remedial and enrichment outcomes. The students have shown their ability in independent and collaborative learning. In remedial and enrichment activities, groups of enrichment students have been directed to help their friends to be successful in remedial. Students' success in the remedial process is the success of enriching other students and vice versa. Each student has received an appreciation of the value according to his effort. The progress of remedial students is 8% to 82%, with an average of 10%. This progress forms the basis for determining the final score for the remedial, intermediate, and enrichment groups as tutors. The difference between the remedial and enrichment appraisal weights was determined using mathematical model 1. The final score of students who become tutors is determined using the mathematical model 3. The three mathematical models above can calculate remedial, enrichment, and tutor results. The use of this model helps teachers or lecturers to be more objective in giving grades. Lecturers' appraisal of student learning outcomes has been carried out in a transparent, fair, and accountable following the differences in the potential competencies of each student. Students have followed the learning process, the assessment process has been carried out properly, the teacher's documentation is complete, and the teacher is more confident.
