Mechanical energy = Potential energy+Kinetic Energy
= ½ m v 2 + m g h
Electrical Power : P = ½ ρ A v 3 + 9.8 Q h (1) (1)

Kyoto Protocol was declared in 2007, launched the clean development mechanism (CDM) as an
effort to realize sustainable development and climate change to anticipates that effects of greenhouse
gas (CO 2 ) and certification (Certified Emission Reduction, CER ) for investments that can reduce CO 2
emissions (CO 2 price : 10 US$/tonne, source: The Australian Financial Review, 07 March 2012).
Theoritical the rate release CO 2 produced from burning fossil fuels can be approximated by the
formula:
TP (CO 2 ) = 0.9 x [(M.CO 2 ) / (MC)] x Cj x Wi

The quality of raw water in West Tarum Chanell will be state in water quality Index (WQI) as formula
:
n
WQI = Σ w 1 q 1 (4)
i = 1
Description:
WQI = water quality index with magnitude between 0 and 100
q 1 = Quality of the scale parameter between 0 and 100
w 1 = parameter with the magnitude of loading units (0-1)
n
Σ Wi = 1
i = 1
WQI scale ranges as follows:
- Category extremely satisfying if it has a value of 91-100
- Good categories, has a value of 71-90
- Category average, has a value of 51-70
- Category bad, has a value of 26-50
- Categories are very bad, has a value of 0-25
West Tarum channel is an artificial ecology that has the function for irrigation and raw water supply of
Jakartas water purification installation.
Parameters of dissolved solids is the parameter determining the quality of water, so the concept of
water quality control is done by reformulate function of water as the energy and material (parameter
for physics, chemistry and biology).
Water quality control in the West Tarum channel carried by the reduction of pollution load calculation
according to some basic parameters of water quality index (Water Quality Index WQI) in accordance
with the principle of energy diversification in development environmentally sustainable.
Economic analysis on optimizing the utilization of the West Tarum channel will include :
The Net Present Value (NPV) analysis used to determine the equivalent value today of cash flow (cash
flow) of revenues and expenditures in the future from an investment plan; criteria for acceptance of an
investment plan with the current method is if the investment plans of the above have a value Positive
current, P> 0.
P = F (1 + d) n (5)
d = i + j + i. j (6)
