Good fish farming certainly requires a place for breeding, hatchery, and growing fish. This service aims to assist the community in cultivating catfish using biofloc media. This assistance has an economic impact on the community, namely helping to meet food needs without buying fish at the market. In addition, it is also efficient to make because all the ingredients for fish farming are easy to get and are readily available around the house. This community service activity included a group of fish cultivators (Pokdakan) in Tanjungkalang Village, Nganjuk Regency. This activity results in a biofloc media with specifications of 4 m in diameter and about 0.8 m – 1 m in height. One biofloc can accommodate as many as 4000 catfish seeds. A B S T R A K Pengabdian masyarakat ini bertujuan untuk mendampingi petani ikan tentang bagaimana cara membudidayakan ikan dengan baik. Budidaya ikan yang baik tentunya membutuhkan tempat untuk penangkaran, pembenihan, dan pembesaran ikan. Pengabdian ini bertujuan untuk membantu masyarakat dalam membudidayakan ikan lele dengan media bioflok. Pendampingan ini memiliki dampak ekonomis bagi masyarakat yaitu membantu memenuhi kebutuhan makanan tanpa harus membeli di pasar ikan. Selain itu, juga efisien untuk dibuat karena semua bahan pembuatan tempat pembudidayaan ikan mudah didapat dan sudah tersedia di sekitar rumah. Peserta pada kegiatan pengabdian masyarakat ini adalah kelompok pembudidaya ikan (Pokdakan) di Desa Tanjungkalang, Kabupaten Nganjuk. Hasil dari kegiatan ini yaitu sebuah media bioflok yang memiliki spesifikasi yaitu diameter 4 m dan tinggi sekitar 0,8 m – 1 m. Satu bioflok bisa menampung ikan lele sebanyak 4000 benih.

The problem is dirty water resulting from a mixture of water and catfish droppings, so it must be replaced periodically. Polluted water is certainly not economical because it requires electricity and energy to replace or purify it again. One alternative to overcome this problem is the biofloc method. According to Faridah [1], the biofloc method is a method of raising catfish by cultivating microorganisms that process catfish farming waste into small lumps, which can then be used as natural food for fish. The biofloc method can simultaneously solve many problems in catfish farming, namely water and electricity efficiency, economical fish feed, and increased productivity of catfish. One area that has a catfish farming group is Tanjungkalang Village in Nganjuk Regency. In this area, catfish farming still uses conventional methods. Cultivation in this area still needs to implement a better method, namely the biofloc method. This service activity aims to assist the people in the village in making biofloc for catfish farming. Of course, this assistance is an effort so that the community can independently make biofloc to increase people's income by applying efficient, effective, and economical catfish farming methods [2-6].
