2.7 Average farm income
The average income is the result of the receipt of farming results
divided by the planting period of the pakcoy plant.

3 RESULTS
This study aims to determine how much capital is needed in making
hydroponic installations measuring 7.5 M x 1.5 M x 1 M and the profit
of pakcoy farming in Arga Indah 1 Village, Pagar Jati District, Central
Bengkulu Regency using analysis of calculating farm production costs
and pakcoy farming revenues. with the method of calculating the R/C
ratio. In this hydroponics system using a deep flow technique (DFT),
which includes planting media, plant installation, nutrition, plant care,
and production costs [2].
3.1. Calculation of Farm Production Costs
3.1.1 Cost capital
The hydroponic system used in this farming research uses a deep flow
technique (DFT) system measuring 7.5 M x 1.5 M x 1 M. Following are
the details of the materials used:
