Efforts to improve family food security are one way in line with Indonesia's commitment to achieving the 17 targets in the Sustainable Development Goals (SDGs). Efforts made to create affordable and accessible family food security include utilizing yard space. However, currently, many households only have limited land. To overcome this limitation, a concept is needed that can overcome this obstacle, one of which is the use of economical floating raft aquaponics techniques. This technique can help provide food sources for families in the form of fish and vegetables in one location simultaneously, using simple materials and tools available in the village. The results of the study show that the management of the floating raft aquaponics system and maintenance are highly dependent on the balance between fish feed and waste and the ability of plants to absorb nutrients from waste leftover fish feed and fish waste. If the management and maintenance of floating raft aquaponics systems are not implemented properly, it will cause failure to fast and decrease water quality due to the accumulation of waste from fish waste and leftover feed.
