2.2.1 Fixed costs
Fixed costs are costs that do not run out in one production process
which include: installation table, seedling tray mat, measuring cup,
waring, pump, and hydroponic netpot (Nova and Endo, 2020). Fixed
costs incurred amounted to Rp 3,546,900. If it is assumed that these
materials can last for 5 years, then the fixed costs will be refunded for
5 years at the amount of IDR 709,380 per year. One hydroponic period
takes 40 days from sowing seeds to harvesting vegetables. That way,
if it is calculated in one year, it has 9 planting periods. if you want to
pay for fixed costs per period, the amount of fixed costs per period is
Rp. 78,820.
2.2.2 Variable costs
Variable costs are costs that are used up in one production process
which include: Packcoy seeds, rockwool, and ABmix nutrients (Nova
and Endo, 2020). For rockwool it can be used for two productions, so
that in one production it is enough with half the rockwool. The costs
incurred are Rp. 120.500.
2.2.3 Total cost
Total cost is the sum of fixed costs and variable costs.
Total cost formula:
TC = FC + VC
= 78.820 + 120.500
= 199.320
2.2.4 Farming revenue
Farming revenue is the total income received by farmers from
production activities carried out and has generated money that has not
been deducted by costs incurred during one production. In the
installation there are 180 planting holes, and if sold the price per stem
is IDR 2.500.
TR = p x q
= 2.500 x 180
= 450.000
