Carbon nanomaterials have been used in various fields such as agriculture because they have properties that allow them to influence plant growth. This research aimed to determine the effect of carbon nanomaterials made from watermelon skin waste as a plant supplement towards the growth of lettuce (Lettuce sativa L.) plants in a hydroponic setting. This research began by making carbon nanomaterial powder based on the two-steps low heating (TSLH) method. The watermelon skin wastes had been dried using an oven and then heated again using a microwave to obtain the carbon nanomaterial sample in the powder form. The carbon nanomaterial samples were characterized using UV-Vis, PSA, and XRD. The effect of the carbon nanomaterial on the lettuce plants was observed in a hdroponic setting. Data collection was carried out by measuring the water height, leaf width, plant height, number of leaves, and wet and gross weights of the lettuce plants. The results showed that the carbon nanomaterials can influence the growth and development of lettuce plants, especially helping plants absorb water and controlling and developing plants’ growth so that they experience more stable growth.
