| Summary: | Aquaponic the result of the integration of aquaculture and hydroponics can be used
as an alternative to the intensification of agricultural land. Red lettuce (Lettuce
sativaVar. Crispa) and Tilapia (Oreochromis niloticus) are agricultural
commodities that have government concerns for improving community nutrition
and also fulfilling good criteria as an aquaponics component. Ammonia buildup
causes problems in aquaponic practices that can damage the fish. Used biofilters
such as bioball can help to reduce the substance. The addition of oyster shells is
expected to provide additional functions to stabilize pH and water quality. This
study aims to determine the effectiveness of using biofilter with the addition of
oyster shells (CKO) in the growth of red lettuce and tilapia and to determine the
effect of plant position in the installation on the growth of red lettuce. A two-factor
Randomized Block Design (RBD) was used, which CKO with bioball (1:1) and
bioball only also ther is 10 plant positions with 6 replications. Measurements were
made of plant growth and biomass, fish growth and survival, water quality (TDS,
EC, and water pH), and environmental conditions. The data were processed using
a two-way ANOVA test followed by the BNJ Tukey test with a 95% confidence
interval. The results showed that the addition of CKO increased plant growth
(number of leaves, fresh weight, and dry weight of plants) and fish growth (length,
weigh,t and survival of fish). The position of the plant closest to the inlet (positions
1 and 2) provides the best growth for the plant (height, number of leaves, dry
weigh,t and fresh weight of the plant) whereas the farther from the inlet the lower
the resulting value |
