Subsurface Flow Constructed Wetland

Water is an asset that is becoming scarce and its reuse is an alternative to preserve it. Social and environmental feasibility motivate the adoption of reuse, but the financial factor can be limited to its use. The objective of this study was to evaluate the economic and financial feasibility for the investment in a domestic wastewater treatment system in which the constructed wetlands could be used aiming at the reuse for irrigation. Instruments such as the minimum attractiveness rate, discounted payback, the internal rate of return and the profitability index were used. The treatment system composed of an equalization tank, a septic tank, horizontal subsurface flow constructed wetland, subsurface flow constructed wetland, and a maturation pond comprising 52 m², demonstrating that it is able to meet the criteria required for reuse. The organic load affluent to the system was projected to 220 mg L-1 at a flow rate of 600 L day-1 of sewage, obtaining removal efficiency above 98% for all parameters, except nitrogen and phosphorus. In the analysis of economic and financial feasibility, it was found that the internal rate of return found for the cash flow considered was 98% and the profitability index according to the present value was 3.28. It was found that the total employed would be recovered in up to two years. With the use of the system, 180 m³ of water would be saved annually, reducing the pressure on the public supply system, in addition to the sewage treatment and the scenic beauty provided by wetlands. Therefore, the system is not limited only to economic gains, but also to social and environmental gains.

Turmeric Extract

Turmeric extract powder was processed product of turmeric which were produced in powder form. This study aimed to determine the value added obtained in the process of producing extract powder, knowing the financial feasibility obtained from the productin process of turmeric into extract powder products. The financial feasibility study uses the calculation of profit and loss analysis, Net Present Value, Internal Rate of Return, Net B / C Ratio, Payback Period, and Break Event Point and Hayami method to determine the added value..The business of extract powder was feasible to obtain, and the Net Present Value was Rp. 290.897.909. The Internal Rate of Return of 13% showed that the rate of return was greater the specified Bank interest rate. Payback Period for 1 year 2 months and B/C Ratio of 1,68. The value added of extract powder obtained a value of Rp. 20.000 per kg, the income value added ratio was 57,14%. The sensitivity analysis scenario showed that both an increased in operational costs of 3%-6% and income decreased by 3%-6% resulting in positive NVP. Therefore, the turmeric extract powder business was feasible. Keywords : Turmeric, extract powder, value added analysis, and financial feasibility

Financial Feasibility

Abstract-While constructing the geothermal cogeneration plant the success of the projects depends upon its financial and market feasibility. A new optimization method is used to estimate financing requirements of investment projects will be presented, as well as a new method to predict the optimal year to sell the investment. A case study is used to illustrate the use of a model to assess the financial feasibility of a geothermal cogeneration plant. The conclusion is that Net Present value , Internal rate of Return and Modified Internal rate of Return should be used to assess financial feasibility of investment projects. In addition to calculating the financial feasibility criteria, assessment models should allow the user to perform sensitivity analysis, scenario analysis, and simulation to analyze risk associated with the investment project. Risk probability matrix is used to obtain the risk priority , which then continued with financial analysis for the feasibility study and also sensitivity analysis. The study shows that the parameter investment value will be increased when treatment is done on risk.Keywords:Financial and market feasibility, Geo thermal cogeneration plant, Environmental Aspects, Sensitivity analysis.
