The availability of land to produce food is decreasing due to infrastructure development making agricultural land increasingly decreasing. Limited land is not commensurate with the increasing demand for food. The solution to overcome this is to apply the hydroponic method. Limited land, especially in urban areas, can be used more efficiently with hydroponics. This research aims to investigate the application of hydroponics directly in an urban context with active involvement in the Valefarm Hidroponik Solo plantation. The Participatory Action Research (PAR) method was chosen to be able to understand better. The findings of this research show that hydroponics can maximize land use, allowing year-round planting, better quality and quantity, as well as water and fertilizer efficiency. Apart from that, the shorter harvest period and easy pest control are the advantages of the hydroponic method.
