1. ENGINEERING PLUMBING AND SANITATION
Compiles Cost Estimate and Shopping ( RAB) Work Plumbing

2. BUDGET CALCULATION PURPOSE OF INSTRUCTIONAL PUBLIC :
Students get the picture basis calculation budget and plan budget at one particular work of plate and pipe that is simple.

3. PURPOSE OF SPECIAL INSTRUCTIONAL : Students earn :
1.Mention factors becoming consideration in making calculation budget.
2.Calculate decrement of the price from a device/ engine every knowing it is carefully

4. BUDGET CALCULATION BASIS
Basically cost estimate expense is the most important thing in executing of making a work.
Blocks in budget mean us to estimate price a substance which we would create accurately and carefully.

5. Some things we need: 1. Analysis book 2. Price factor of material
3. The price of worker fee
4. Security and safety in work place
5. Transport material to work place

7. Things we need to know :
1. Price decrement of engine : Every engine utilized will surely become breakdown, on that account was function of time

8. II. Goverment Tax
Every works must pay [for] at government equal to so much percentage of the price / offer. This tax for Indonesia in the form of Pajak Penambahan Nilai ( PPN ) and level determined by government is equal to 5%.

9. To be more sharpness let us see the example of decrement price from an engine :
The price of a new engine Rp
Decrement after 1 thorium. 10 % out of Rp = Rp
The price in year to Rp
Decrement after 2 thorium. 10% out of Rp = Rp
The price in year Rp
Decrement after 3 thorium. 10% out of Rp = Rp
And so on
It is of course after 10 thorium. The engine had not been valuable again

14. 5. Risk and advantage
Risk that is possible for us are natural if for example : flooding, usage of new material, usage of new device, direct action worker, new engineering energy.

15. 6. Government tax.
Tax which must be paid at government every work we do.
In Indonesia in the form of PPN

16. Price fixing : Contingency from material = 30%
from the price of clean material
Contingency from fare = 100%
from clean fare
Risk and advantage = 10% from
subtotal 1
The Government Tax PPN = 5%
from subtotal 2

17. EXAMPLE OF 1 : Price calculation of material :
The price of cleanness material Rp. 1,00
Contingency from material 30% Rp. 0,30
Total sub Rp. 1,30
Risk and advantage 10% Rp. 0,13
Total sub Rp. 1,43
PPN 5% Rp. 0,07
The price of dirty material Rp. 1,50

18. Calculation of Fare : Cleanness fare Rp. 1,00
Contingencies from fare 100% Rp. 1,00
Total subs Rp. 2,00
esiko and advantage 10% Rp. 0,20
Total subs Rp. 2,20
PPN % Rp. 0,11
Dirty fares Rp. 2,31

19. EXAMPLE OF PROBLEM :
1.How much/many % decrement the price per year. a grinding machine the price Rp Appraised the engine having age 8 year. How much the price of the engine in year to 3 ?
2.After 5 year with the price of derivation of 5% from new price, nitrogen the price of from an engine Rp New price calculate from the engine !
