Phytochemicals At present, researchers have been studying the possibility of using biological natural coagulant to decrease the hazards of using inorganic coagulants. This study aimed to evaluate the effects of teak leaves, talisay leaves and their combination powder towards physical parameters of freshwater water quality by using different dosages of the coagulant. The teak leaves and talisay leaves were collected from that already fallen on the ground and were dried before being grinded finely into powder. The water samples were collected from Tasik Elham of UiTM Cawangan Perlis and their initial reading of physical parameters such as pH, salinity, conductivity, dissolved oxygen, total dissolved solid and absorbance were recorded before and after the experiment when applied with different dosages (0.5 g, 1.5 g, 2.5 g and 3.5 g) of natural coagulants in jar test. Characterization of natural coagulants were determined before and after treatment using FTIR. Based on the result, most of the lower dosages for all the coagulants show positive effects towards the parameters observed except for absorbance reading. Ultimately, the usage of teak leaves powder as the natural coagulant showed the best result as it gave positive result to a few parameters including increment of pH level with 9.02 %, highest decrement of conductivity with 16.83 %, highest improvement of the dissolved oxygen level with 76.19 %, lowered the total dissolved solid with 21.70 % which was higher compared to other two coagulants. Hence, it can be concluded that teak leaves powder showed the highest potential as natural coagulant to help in improving quality of freshwater water sample. 2020-07 Thesis https://ir.uitm.edu.my/id/eprint/32713/ https://ir.uitm.edu.my/id/eprint/32713/1/32713.pdf text en public degree Universiti Teknologi Mara Perlis Faculty of Applied Sciences
