Prioritising Optimal Actions in Pandemic Management: An Analytical Hierarchical Process Approach
Get PDFThe stage of the decision-making process is the most complex one, and it is necessary to emphasize a variety of aspects to have a positive effect on the stage that comes after it. In order to resolve a problem or make an evaluation of something, decisions need to be made by the decision maker, who should be free from any bias or outside influence. This study concentrates on the operation in North Port, Port Klang, Malaysia, which is the main pulse of the Malaysian economy, aiming to deal with the pandemic by making the most accurate decisions possible systematically for those decisions to be able to deal with the pandemic that has struck. It has been determined which categories contribute to the actions that need to be taken to deal with the pandemic at the port, and all these categories have been enumerated so that specialists can evaluate which categories are the most influential. For data analysis, the Analytical Hierarchical Process (AHP) method is utilised, and the findings also assist decision-makers in making the appropriate choices. Consequently, based on study\u27s findings, it was discovered that the primary criterion that needs to be prioritized in North Port\u27s response to the pandemic is health and safety, which received a score of 20%, followed by technology (18%), PPE (18%), MCO (12%), wedges (9%), manpower (8%), damage (6%), origin country (5%) and lastly delay time (5%). Therefore, the port side may use the possibility presented by this study to systematically decide any problem that may arise at the management level

Characterisation of Adsorption Inhibitors of Cacao Peel Extract to Protect the Rate of Corrosion on Steel Surfaces
Get PDFResearch has been conducted to investigate the use of biomass waste inhibitors derived from cocoa pod extract to reduce steel corrosion rates. Steel samples were pre-soaked in the inhibitor for 24, 72, 120, and 168 hours, followed by immersion in a corrosive HCl medium for 48, 96, and 144 hours. The corrosion rate was evaluated using the weight loss method, optical microscopy, scanning electron microscopy (SEM), and atomic force microscopy (AFM). Additionally, X-ray diffraction (XRD) phase analysis and Density Functional Theory (DFT) were employed to examine the HOMO/LUMO contours, molecular geometry, and structure. The weight loss method yielded the best results, with the lowest corrosion rate of 0.2972 mg/cm²/hour and inhibition efficiency of 74.71%, observed when the steel was soaked in the inhibitor for 168 hours and immersed in HCl for 48 hours. Morphological analysis using optical microscopy and SEM revealed that longer immersion in the inhibitor resulted in a smoother surface with fewer cracks. XRD analysis identified four distinct peaks corresponding to crystalline Fe and C phases, indicating reactions between the steel surface and the inhibitor. AFM analysis demonstrated a strong correlation between the duration of immersion in the inhibitor and the extent of adsorption on the steel surface. The DFT analysis showed that a molecule’s corrosion inhibition potential increases with higher EHOMO values, as this facilitates electron transfer to the steel surface. The optimization and computational analysis of tannin components interacting with the steel surface revealed a high inhibition efficiency of 80.21% for the cocoa pod extract inhibitor, suggesting its potential as an effective and sustainable solution for industrial corrosion control. These findings highlight the need for further optimization and scalability studies, with implications for the widespread use of natural inhibitors in various corrosive environments

Effectiveness of Fixed \u27Pole-Jurin\u27 Compared to Conventional Methods in Practical Work in Kuching Polytechnic Sarawak : A Comparative Study
Get PDFAbstract
Land survey is a measurement work on the ground marked with boundary stones or temporary bench mark while using tools such as theodolite or total station and two prisms to measure the angle and distance between certain points in the field. Usually the prism will be erected on rear and front view stations as markers and the angle will be measured using the total station. This practice is common for Diploma in Geomatic (DGU) students to carry out traverse survey work around the Kuching Polytechnic Sarawak (PKS) area every time they practice it. The practice of cadastral surveying in Sarawak allows the use of \u27pole-jurin\u27 to replace the prism in the marking of the observed measuring stations. Usually in minimal use only one prism is carried along with the total station. Thus, the large amount of equipment, weight and long period of time providing the station using \u27pole jurin\u27 became a constraint for DGU students in PKS. Pole-jurin is permanently designed using readily available materials. The results showed that the weight of the fixed pole-jurin was 1 kg and the time to set up for only 2 minutes on average. Prototypes are tested for effectiveness throughout field tests that are evaluated in terms of durability. Questionnaires are carried out to obtain feedback from students and lecturers. In fact, the questionnaire found that the 4th item fixed pole-jurin was easier to use with the highest score of 4.67. Therefore, the use of fixed pole-jurin remains easier to take to the field and stored in survey workshops using minimal space. Thus, in the cadastral survey work in PKS students will bring one total station, one prism and the rest is a pole-jurin whose number depends on the need.
