diseases. Fruit does not have a layer of wax as told
before so farmers are not ready Because the fruit field
is easily attacked by pests. The level of pest attack is
very high when the farmer late to do the packaging of
fruit. Conversely wrapping fruit when the fruit is still
too small also makes fruit to fall out.
Fertilization done by farmers is less causing the
growth of plants disturbed. The high price of non-
subsidized fertilizer is one of the causes of the lack of
fertilizer which resulted in low yields other than
because farmers' crops generally have not entered the
productive age of 2-10 years.
The cost of drugs to treat diseases tend to be high
because of the variety of pests and diseases
encountered. The lack of key inputs that directly
affect fertilizers and medicines causes far-reaching
crop yields. The problem of the off-farm subsystem,
the problem faced is the low selling price due to the
low quality of the crop. The harvest is strongly
influenced by the physical appearance of the fruit,
such as the color and smoothness of the fruit skin. The
color of the fruit is too old due to poor wrinkling
mistakes. Unscheduled harvests lead to
overproduction but the bad consequences of the fruit
sale price have been reduced.
The marketing of this fruit resulted in many
farmers began to rely on the sale of transplanted
seedlings. In the field seen some farmers tend to focus
on grafting graft so that the harvest is low. The farmer
cuts the fruit on the transplanted portion so that the
nutrients are focused on root growth. Transplants
should only be done when the plants are grown,
which is around the age of two years. Young breeds
cause the transplant plants to die more easily. The
price of citra water apple seeds in the market reaches
Rp 10,000-Rp15 000.
3.2.2 Analysis of the Income of Citra Water
Apple Farming System
The analysis of farming is done by calculating the
level of income and R / C ratio of cashew water
farming system. Respondent analysis of cashew water
farming system done in this research is 30 people.
The farming analysis conducted refers to the concept
of income over the cost of cash costs and total costs.
Cash costs can be interpreted as costs incurred in
cash such as the cost of purchasing production
facilities, the cost of labor outside the family and
taxes. The total cost is the cash cost plus the
calculated cost. Calculated costs are expenses that are
not in cash such as fees for family labor use,
depreciation of equipment and the cost of
counterparts for land or lease of land.
The analysis of farm income is useful to give an
idea of the advantages or disadvantages of a farm that
is calculated based on the amount of revenue earned
less the cost incurred. Analysis of farm income
includes an analysis of revenue on cash costs and
income analysis over total costs. In the cost
component, the costs incurred by the farmers consist
of cash costs and costs are taken into account.
Analysis of farm income is done by comparing
respondent farmers based on plant age.
3.2.3 Farming Costs Structure
Expenditure or expense is the entire sacrifice of
economic resources in the units of money (rupiah)
required to produce the product within a production
period. Production cost is all expenses incurred to
produce a commodity or product either in cash or
taken into account. The cost of farming is divided into
cash costs and calculated costs. The calculation of
cash costs includes the cost of cutting the harvest
payments, the purchase of fertilizers, medicines, fruit
wrappers, family labor and other costs such as tax
costs. Calculated costs or non expenses include
depreciation expenses and counterpart fees for family
labor, and land. The balancing cost for land or land
rent is included in the cost is taken into account
because the average farmer has his own land.
Depreciation cost of equipment in each used by
farmers have the same value because the comparable
farming is a farm which in the same cultivation
technique so that the equipment used for farming is
relatively the same.
