Tabel 2. Construction cost for microhydro type Vortex gravitation Economic analysis of investment development of small-scale micro power plants in West Tarum channels that includes the break-even analysis, ratio analysis and cost benefit analysis of Net present value can be seen in attachment 1, the analysis of rate of return (IRR analysis) to analyze the level of interest rates can be seen in attachment 2, In Figure.13 the breakeven point (BEP) investment in the micro power plants reached 5 th . www.theinternationaljournal.org > RJSITM: Volume: 02, Number: 02, December-2012 Page 44
Figure.13. Break even point 2.6 Modeling of Water Quality improvement Modeling take assume that the West Tarum channel section Bekasi weir to Cawang pump house have no illegal channels and no illegal sewer line that goes to the West Tarum. Pattern modeling operations performed by the seasons: Operation rainy season the amount of water contained in the local river is least that dry season, so the water quality in rainy is better than dry season. In rainy season; the debit of local river is 30% (maximum), while the remaining 70% will be supplied from Jatiluhur dam . In dry season all raw water will be supplied from Jatiluhur dam. Based on data analysis of water quality changes in West Tarum channel, have 5 parameters not in accordance with the standards in Government Regulation No. 82 of 2001, namely pH, dissolved oxygen, BOD, Turbidity and Fecal Coli. Decrease the parameters pH, Dissolved Oxygen and BOD due to decay caused by many sedimentation. Increased turbidity parameters resulting grain size of soil erosion and resulting siltation in the channel. The increase in the value of the parameter Fecal Coli caused the entry of dirt human / animal at a body of water, especially water suplisi from local rivers and the inclusion of household waste to the West Tarum channel. Based on observations that the content of dissolved solids from the river Bekasi (372 mg / l) is bigger that dissolved solids from the West Tarum channel (211 mg/l), and so direct mixing of raw water from from Jatiluhur with water from the river Bekasi suplisi be avoided. Block diagram modeling of water quality improvement with diversification of energy can be seen at attachmenmt 3. In modelling at attachment 3, can be present that the amount of electricity generated and CO 2 emission reduction varies depending on the amount of usage of raw water in instalation purification in Buaran, Pulogadung, Pejompongan and magnitude of run off water weir Bekasi. III. CONCLUSIONS Modeling of energy diversification for self improvement of water quality is a reformulation of water concept of improved water quality by controlling the parameters of dissolved solids with utilizing the energy contained in water flow on the downstream side. Bekasi weir is an optimal location for the modeling location because it can be optimazied the water as energy and as material. The Basic assumption of modeling are no direct water mixing between water from Bekasi river and from Cikarang’s West Tarum channel, and improve the levees or banks of the West Tarum channels (section Bekasi weir – Cawang intake and pumping station) to prevent the household waste from surrounding settlements throughout the West Tarum channel does not go into water bodies and affect the quality of raw water. Modelling of Energy Diversification for Self Improvement of water quality (attachment 3) can be present: a. Reduction of total dissolved solids parameter is the main parameter in determining water quality by separating the management of raw water from West Tarum channel and water suplition from local river on downstream side. www.theinternationaljournal.org > RJSITM: Volume: 02, Number: 02, December-2012 Page 45
