for Sustainable Living

1. Improving the quality of aquaculture water: Adharani,
Soewardi, Syakti, & Hariyadi (2016) concluded in their study
that the use of biofloc can improve water quality, as evidenced
by a drop in the concentration values of total ammonia
nitrogen (TAN), ammonia, nitrite, and nitrate parameters. In
this situation, biofloc functions as a biocatalyst, efficiently
converting organic waste into stable organic matter and
lowering culture water’s ammonia, nitrite, and nitrate levels.
Biofloc will keep the water clean and limit disease risk in farm
animals.
2. Feed efficiency: Wanja, Rebhung, & Sunadji (2020) showed
that biofloc technology affects the efficiency of feed usage
in milkfish. Because the microorganisms that dwell in the
biofloc also offer nutrients to the farm animals, the biofloc
technology system allows for less commercial feed. It
will help minimize feed expenditures while reducing the
environmental impact of surplus undigested meals.
3. Increased productivity: Because biofloc works as an
additional source of nutrients in biofloc technology systems,
higher population densities of farmed animals can be
reached. It was consistent with the findings of Suhardianto
and Hartari (2019), who discovered that the density of fish in
ponds can rise thrice. This increased density has implications
for improved productivity inside the same production unit,
enhancing efficiency and profitability.
4. Environmental sustainability: Organic waste from farmed
animals in conventional aquaculture systems can pollute
the surrounding water. The risk of environmental pollution
can be minimized by using biofloc technology since organic
waste is transformed into solid biomass and repurposed as
feed or organic fertilizer. Ma’in, Anggoro, & Sasongko (2013)
state biofloc technology has reduced aquaculture waste.

Biofloc technology has achieved significant improvements
in recent years. This method was first solely used in intensive fish
farming. This technique, however, has grown into an efficient system
