The purpose of this study is to investigate the potential ligands of Chromolaena Odorata plants which contributes to the wound healing process. The ligands involved were phytol, ß-Caryophyllene, and 3,3-Dimethyl-1,2,4-cyclopentanetrione. This work addressed molecular docking simulations between the chosen ligands and Matrix Metalloproteinases (MMP) as the primary viral protein/receptor. The binding modes of the protein-ligand interactions were analysed. 9 poses of docking modes were obtained from the simulation. The ligand-receptor with the lowest interaction energy is the potential candidate for wound healing treatment. In summary, 3,3-Dimethyl-1,2,4-cyclopentanetrionehas been chosen to be the best docked complexes as it shows the lowest energy among the other ligands with value of -7.1 kcal/mol.

Electrocoagulation (EC) is a reliable technology for wastewater treatment. It has been applied in treating various source of wastewater from tannery, electroplating, dairy, textile processing, oil and oil-in-emulsion. It is crucial to strengthen the fundamental of the EC treatment on oily water sample for further studies. However, in depth studies on the performance of EC treatment on oily water sample is still requires in depth studies. In this research, a series of experiment has been conducted on the performance of EC treatment including effect of the amount of sodium chloride (NaCl), applied voltage and pH to determine the efficiency in oil removal. The EC treatment took placed in room temperature and constantly agitated for 30 minutes meanwhile samples were collected for every 5 minutes for UV–Vis analysis. Then, the efficiency of the treatment was determined followed by simulating the results in kinetic models. The highest efficiency of EC treatment was achieved with 89.26% of oil removal with the addition of 7.5g of NaCl, 4V of applied voltage and at pH 6. In addition, the results have better fitness towards pseudo second order (PSO) which indicates the mechanism of EC treatment is chemisorption.
