| Summary: | Leachate is a liquid resulting from the fermentation process of organic waste,
especially those containing a lot of water such as vegetables and fruits. Leachate can
be used as a nutritional alternative for hydroponics. The use of hydroponic systems for
the cultivation of Mentha spicata or spearmint has been widely used in recent years.
Research on the use of leachate (L) from the bioconversion of watermelon waste by
Hermetia illucens L. larvae as a mixture with commercial hydroponic nutrient AB Mix
(ABM) was carried out to see the growth and yield of spearmint plants produced.
Spearmint seedlings aged 14 days as many as 7 plants were planted in rockwool in a
netpot (? 4.5 cm), then placed on a perforated infraboard that had been attached to a
tray (long 47 cm x wide 33 cm x high 14 cm) containing hydroponic nutrient solution.
The combination of hydroponic nutrients used was ABM 100%, ABM 75%: L 25%,
ABM 50%: L 50%, ABM 25%: L 75%, and L 100% with 5 repetitions in each
treatment. Spearmint hydroponics was placed on a screen house (long 3 m x wide 2 m
x high 2.25 m) with a UV plastic roof. The analysis results of the macronutrient and
micronutrient content from the mixture of ABM and L showed that nitrogen, potassium
and calcium in several treatments were within the standard range of hydroponic
solution nutrients. The combination of AB mix and leachate in hydroponic nutrient
solution gave a significantly different effect on the parameters of dry weight, plant
height and shoot root ratio but not significantly different on the parameters of the
number of leaves, wet weight and yield index of spearmint plants. The results showed
that the nutrient solution ABM 25% : L 75% resulted in higher leaf growth, wet weight
and yield index of spearmint plants than other treatments.
