Kale (Ipomoea aquatica) is a highly nutritious vegetable and one of the important horticultural commodities in Indonesia. Hydroponic cultivation method is gaining popularity due to its land-use efficiency and water saving. However, this method also faces challenges in the form of disease attacks, especially rust disease caused by fungi from the genus Puccinia. This study aims to evaluate the factors causing rust disease in hydroponic kale plants at the AEE Sidoarjo Hydroponic Production House, and identify effective control methods. For 30 days, observations were made to identify symptoms, take samples for pathogen analysis, and test the effectiveness of various fungicide treatments. Results showed that control through the use of organic fungicides such as neem oil and potassium soap, as well as optimal environmental management, was effective in reducing disease symptoms and increasing plant productivity. These findings provide practical solutions for hydroponic farmers to improve plant health and production yields, and contribute to sustainable hydroponic farming practices in Indonesia
