colloids, and other pollutants to aggregate and form larger, heavier particles known as flocs. Cleaner water is produced when these flocs are more readily removed from the water by procedures like filtration or sedimentation. The purpose of this study was to lower the number of contaminants in the wastewater sample. The expense of employing a chemical coagulant can be decreased by using a natural coagulant. Papaya, roselle, and cactus plants were the primary plants and seeds used in this investigation. Each plant and seed exhibits different levels of turbidity, total suspended solids (TSS), and pH clearance removal. The average percentage of turbidity removal is -135.37% for papaya, 41.35% for cactus, and -13.56% for roselle using different dosages of coagulant. For TSS removal, the average percentages are 33.31%, 56.65%, and 72.89% for each plant, and each plant also exhibited no reduction in pH level. Palm Oil Mill Secondary Effluent (POMSE) wastewater was the sample used in this study. Using the Jar Test, which involves preparing the plant or seed into a powder, the efficacy of removal for turbidity, TSS and pH has been determined. For cactus and papaya seeds, the dosage ranges from 0.3 to 0.7 grams, whereas for roselle seeds, it is between 0.03 and 0.07 grams. It shows that by using papaya seed as natural coagulant, the turbidity and pH is increasing but decrease for TSS removal, while cactus is decreasing for turbidity and TSS removal and slightly increasing for pH reading as a result. The roselle seed is increasing the pH reading but decreasing for TSS removal and the turbidity decrease when dosage at 0.03 g/L. The amount of dosage used to treat the wastewater sample determines the percentage elimination of these parameters. Based on the experiment occur, it was found that cactus shows a better performance as natural coagulant than papaya seed and roselle seed with the percentage of removal for turbidity being 41.35% and 56.65% for TSS removal.
