The COVID-19 pandemic that has lasted more than a year has brought down the family's economy. Activity restrictions imposed by the government to suppress the increase in the number of sufferers resulted in the cessation of community economic activities, especially in the informal, non-essential and non-critical sectors. The work from home regulation allows economic activities by utilizing the limited land around the house. Hydroponic farming is an alternative activity because it is easy and does not require enormous costs. This study develops a micro-hydroponic system that is suitable for the limited availability of land in urban housing. Internet of things (IoT)-based control and monitoring system is applied to manage the hydroponic system from anywhere and anytime using a smartphone. Experiments using lettuce during one growing season show that this hydroponic system with IoT control can produce fresh and quality vegetables consumed by themselves to increase endurance. The sale of the harvest can provide an additional income of 225 thousand rupiahs for an area of one square meter. This extra income is expected to restore the economies of urban communities that have limited housing areas and work in the informal sector. © 2021 IEEE.
