The hydroponic system is increasingly popular in Indonesia. In 2014, 597,674 tons of pakcoy were harvested from hydroponic products. However, the hydroponic system uses mix AB fertilizer which is relatively expensive. Moringa leaf and rice washing water have high mineral and vitamin content. There are cytokinin in moringa leaves which are useful for growth so that they can be used as organic liquid fertilizer. This study aims to determine the response of pakcoy growth to the provision of organic liquid fertilizer made from moringa leaves and rice washing water which is relatively cheap. Organic liquid fertilizer is made through the process of moringa leaf fermentation and rice washing water. The treatment given is in the form of 40% AB mix and 60% fermented organic liquid fertilizer. This treatment showed the results in the form of increased leaf size, number of leaves, stem diameter and weight per sample. The addition of organic liquid fertilizer to Pakcoy resulted in an increase in leaf width and length, number of leaves and weight per sample.
