Phytoremediation is a relatively new approach to treat wastewater contaminated by organic and inorganic substances including heavy metals. The effectiveness of two aquatic plants, Centella asiatica and Eichhornia crassipes, were evaluated for their capabilities in removing copper from copper solution. The aim of this study is to determine the potential of these aquatic plants to act as hyperaccumulators. The aquatic plants were put in 8 liters of solution containing 1.5 mg/L, 2.5 mg/L and 5.5 mg/L of copper, for a period of 21 days. Analyses of heavy metals contents were conducted using an Atomic Adsorption Spectrometer. Results showed an increase of copper within the plants' roots and shoots tissues and a decrease of copper concentration in the solution. The maximum removal of copper in the solutions containing Centella asiatica was 99.6 % as compared to 97.3 % in solutions containing Eichhornia crassipes. Centella asiatica accumulated a maximum amount of copper of 1353.0 mg/kg whereas Eichhornia crassipes accumulated 1147.5 mg/kg of copper in their roots. The accumulation of copper of more than 1000 mg/L in plant tissues indicate that both aquatic plants can be considered as hyperaccumulators of copper. Roots tend to accumulate a higher amount of copper than shoots due to translocation process. Significant removal of copper were obtained at p<0.01 for containers containing both aquatic plants, indicating that Centella asiatica and Eichhornia crassipes can be utilized in the phytoremediation method to remove copper from wastewater.

The used of additive enhance the surface of the membrane layer and can be choose from various material. Examples of commonly used additive in membrane are Polyethylene glycol, silica oxide, cellulose acetate and Polyvinylpyrrolidone. Silica oxide was proven have ability to minimize the fouling problem hence increase hydrophobic properties of membrane. Silica also can be extracted from rice husk ash, sugarcane bagasse, sorghum vularae seed and kenaf by precipitation method, biodigestion and sol-gel process. Silica extraction from sugarcane bagasse was chosen as the organic additive for membrane formation. In order to investigate the suitability of the material, several characterization test have been conducted. There are thermal, microscopic and spectroscopic analyses. Thermal gravimetric analysis was performed on sugarcane bagasse to determine the amount of silica that can be extracted from it. Results of TGA on sugarcane bagasse show that the peak temperature at 315.70 °C are defined as crystalline melt. After the melt transition, the baseline takings to a slightly lower position than the pre-melt baseline. The post-melt baseline changes slope as the sample begins decomposition while TGA extrapolated onset temperature of 241.56 °C as this sample decomposes. The analysis of microscopic shows that the addition of silica from sugarcane bagasse changed the surface structure of the membrane especially at top layer and sub layer. Sugarcane bagasse show bands for carboxylate (COO-) and hydroxyl (OH-) groups. The availability of negatively charged groups at the surface of sugarcane bagasse shows potential to be used as additive in membrane fabrication.

This study aims to examine the level of employer satisfaction towards industrial training students of the UiTM Pahang Civil Engineering Diploma Program and identify employer satisfaction factors for industrial training students from aspects of knowledge, personality, generic skills, and soft skills. This study is focused on semester four students undergoing industrial training. This study was conducted on 158 respondents from various organizations. Using the important relative index (RII), the level of important factors was ranked through the value of the index.  Findings show the highest employer satisfaction is towards the student mastering their knowledge, adhering to the working hours, improving their skills and knowledge, and communicating well with co-workers. Besides, it also shows a good correlation between knowledge and personality among industrial training students. This study found that industrial training students of the Civil Engineering Diploma Program had a good level of control over all four domains. Overall findings showed that employers are satisfied with the industrial training students of the UiTM Pahang Civil Engineering Diploma Program. This study is important to measure the effectiveness of the industrial training syllabus in terms of achieving the program outcomes addressed in the syllabus

There are several pollutants that can harm our environment. Oil and grease are one of the examples of a pollutant that can cause a severe environmental problem. The highest concentration of oil and grease inside the sewer system can cause the sewer to clog that can lead to overflow. It can affect not only to the environment but can also affecting our health.  There are various methods of oil and grease removal that one of the examples is by using adsorption method. This method commonly uses activated carbon that is one of the effective adsorbents. Although effective, the cost for activated carbon is expensive thus a study was conducted by using agricultural residues as alternative adsorbents for oil and grease removal. This study objective is to determine the ability of two adsorbents, which are sugarcane bagasse and banana pith as an adsorbent in removing oil and grease from wastewater. It involved the characterization of adsorbent and the performance studies of the adsorbent. The adsorbent was characterized in term of physical and chemical characterization. Dosage and contact time are the parameter used for performance studies, to see the ability of adsorbents in removing oil and grease.

Student-centered learning (SCL) is one of the teaching methods commonly used nowadays as it encourages the active participation and engagement of students in the classroom, especially for the engineering theoretical subject. This study is aimed to examine the factors of students’ involvement and participation towards the SCL Teaching Method in terms of the activities, benefits, problems, and limitations of student involvement. The quantitative data are obtained from the responses of students that enroll in an engineering theoretical subject in the Universiti Teknologi MARA (UiTM) Pahang Civil Engineering Diploma Program. These questionnaires were being classified into five major factors that are the formation of group studies for SCL activities, activities conducted for SCL teaching method, benefits that they gain from SCL method, problems that they encounter during SCL, and suggestions for student improvement towards the activity SCL session. The collected data were analyzed quantitatively by using the percentage and mean method in SPSS computer software. The Relative Importance Index (RII) system was used to quantify the relative importance of involvement factors. This study revealed three main factors affecting the participation and engagement of students in the classroom. This study has an important contribution to help academicians to improve and enhance their teaching method to achieve the objective of the SCL method in the future.
