Abstract:
Aquaponics is a hydroponic farming
system that is combined with aquaculture or fish farming as a source of
fertilizer for plants. Aquaponics in this study was carried out to grow black
rice as an alternative technique for growing rice, as a means of literacy for students
about urban farming, especially the hydroponic system, and as a means of
improving people's nutrition from the products produced. This research was
conducted at State Vocational High School 1 Malang, as part of learning on the
competency of Agro-business of Food Crops and Horticulture, especially the
subject of Agribusiness Food Crops and the subjects of Creative Products and
Entrepreneurship.
Rice
hydroponic cultivation is carried out in stages, namely preparation of planting
media and planting containers, replenishment of planting media, ripening of
seeds, seeding, seeding, weeding, weeding, checking water flow, installing
nets, harvesting. The planting media used were solid organic media, namely
manure and husk charcoal. The type of rice planted is black rice.
The
types of fish raised in this aquaponic system are catfish. Catfish cultivation
is carried out in stages, namely pond preparation, stocking of catfish seeds,
feeding, sorting, harvesting.
For
rice cultivation carried out in the aquaponics system, rice has produced rice
grains, but the type of rice harvested does not contain rice. This is due to
the location around the aquaponics system there are shady trees that interfere
with plant growth. For the cultivation of catfish, the growth is rather long
because the catfish seeds are spread too small and the feeding of catfish
cannot be optimal.
This
study also produced a learning module for rice aquaponics and fish to be used
as teaching material in the Agribinis subject of Food Crops
Aquaponic
rice cultivation and catfish can be used as a means of student practice for the
development of urban agriculture and literacy facilities.
