Combined Cycles

The paper presents a thermo-economic analysis of gas/steam combined cycle. The stated objective is achieved by optimizing thermo-economic parameters for simple combined cycle (large and medium range) and to apply this to economic model of these cycles. The economic parameters evaluated in the present study include discount cash flow rate of return (DCRR) and gross payout period (GPO), two terms commonly employed in engineering economic analysis. DCRR and GPO are calculated for various electric sale and fuel prices. It has been found that maximum value of DCRR and minimum value of GPO are found with large size plant.

This study was designed to estimate the economic analysis of locust bean processing and marketing in Ilorin, Kwara State, Nigeria. Primary data was used and purposive sampling technique was adopted to select the respondents used for the study. A total number of 60 respondents were interviewed. The data collected were analyzed using inferential statistical tool such as regression analysis. Budgetary analysis technique was also used to analyze the profitability of locust bean processing and marketing in the study area. Majority of the processors and marketers are making profits; 68.3% operate above breakeven point while 26.7% operate at breakeven point and the rest 5% was below the breakeven point, this indicates that they neither profit nor lost. The regression analysis result shows that quantity processed, family size and years of experience in processing are significant at 1%, 5% and 10% respectively while education level and stall rent is negative and significant at 1% and 5% respectively. F- Test also explained that independent variables are jointly significant at 1% probability level with an adjusted R2 of 78.9%. The overall rate of return on investment indicates that average rate of return is 0.5 (50%), which is positive. It is therefore concluded that profit made by the processors and marketers can be improved on by increasing the quantity of locust bean being processed through adoption of newly discovered method of processing and improved method of preservation, packaging and marketing of the product to international standard by reducing the odour of the product without the loss of essential nutrients and palability in order to generate foreign exchange. Also, rules and regulations against cutting of economic trees for alternative uses should be enforced to maximize their values. DOI: http://dx.doi.org/10.3329/ijarit.v2i2.14012 Int. J. Agril. Res.

Petroleum downstream industry in Riau Province is still not optimal. The data shows that from 98,892,755 barrels lifting oil each year only 62,050,000 barrels could be processed in refinery unit II Dumai operated by PT Pertamina. There is a potential of 35-40% of downstream industry. Indonesian Government through The Ministry of Energy and Mineral Resources declared the construction of a mini refinery to boost oil processing output in the downstream sector. A feasibility study of development plan mini refinery is needed. The study includes production capacity analysis, product analysis, development & operational refinery  analysis and economic analysis. The results obtained by the mini refinery capacity is planned to process crude oil 6000 BOPD with the products produced are gasoline, kerosene, diesel and oil. Investment cost consist of is capital cost US $ 104419784 and operating cost US $ 13766734 each year with net profit earned US $ 12330063/year and rate of return from investment 11.63%

Economic Rate Of Return

This research purpose to analize productivity and economic rate of return on small, midle and Cooperative enterprise in Piyung rigion. Productivity and  economic rate of return index are very importance to measure output and input on production process, and asset effectivness. In generally productivity and economic rate of return are low, althought we  are sustainable in business. I want to known, what factors are influence in business and motivation their  have. Indonesia have a great micro, small, midle and cooperatve enterprise. Base on statistics 99.8% consist of its enterprise and 0,2 % is big enterprise. They are contribution on lobour obsorb and  social safety net.  Sample size are sixty   got from three subrigions in Piyungan as : Sitimulyo, Srimartani and Srimulyo, with stratified random sampling. Research data are from small, midle and cooperative enterprise, who have business in various item. Discriptive statistic model we use on research problem, ratios as index productivety and  economic rate of return  to mesure businessment performent. The following are statistic index : productivety 16,56%,, economic rate of return 8.02%, businessmen 7.300 or 14,68%., jobless 8.105 or 16,30% and population amoun 49.711.
