Empirical Analysis of Economic Viability and Cost of Installation of 3 HP Solar Irrigation Pump in Jaipur, Rajasthan

With the increase in population, urbanisation and development in India, the demand for energy has increased in recent years. Today, India relies heavily on fossil fuels to meet its energy requirements. Hence, this study analyses the economic viability of 3 HP solar irrigation pump for farmers of Jaipur, Rajasthan. Since, solar irrigation pump is now being preferred over diesel irrigation pumps in the study area. Rajasthan was selected purposively because it receives the highest annual global radiation. Jaipur was selected because the number solar irrigation pumps were maximum. Payback period, net present worth, benefit cost ratio and internal rate of return was used to analyze the economic viability. From the results it was clear that the adoption of solar irrigation pumps was economically feasible in the study area.

Financial Evaluation of Short Rotation Tree Crop under Agroforestry System in Tamil Nadu

This paper presents the financial evaluation of short rotation tree crops under agroforestry system. Agroforestry involves the cultivation of two or more plant species with woody perennial in a single fragment of land. Multi-stage purposive sampling technique was employed in selection of the district, blocks and villages based on area under forest cover. Dharmapuri district of Tamil Nadu was taken for this study. Though there are many short rotation tree species grown in the study area, farmers prefer Malabar Neem (Melia dubia) for its multiple uses. The prominent agroforestry systems in the study region viz. Agri-Silviculture and Silviculture were selected. The primary data was collected from 80 sample farmers for the agricultural year 2018-19 and the sample respondents were surveyed from January to February, 2020. Financial analysis viz., Benefit-Cost Ratio (BCR), Net Present Worth (NPW) and Internal Rate of Return (IRR) were performed to check the feasibility of the investment in Agri- Silviculture and Silviculture system. The results indicate that additional income (68%) and meeting emergency cash requirement (67%) were the major reasons for adopting short rotation tree crops. The Net Present Worth per hectare in Agri-Silviculture and Silviculture system was Rs. 3,43,823 and Rs.1,97,909. BCR of Agri-Silviculture system has been found to be higher (2.01) than Silviculture system (1.66). Growing Malabar Neem with agricultural crops is more beneficial when comparing trees alone, it is capable of providing income round the year in a short span of time. Using tree crops as a contingency fund allows the farmer to meet the unforeseen expenses.

Design and Engineering Economic Analysis of a Variable Refrigerant Flow (VRF) and Mini-Split Air Conditioning System

Design and Engineering Economic Analysis of two widely used Air-Conditioning (AC) systems, Mini-Split and Variable Refrigerant Flow (VRF), in the new Engineering Complex Building under the same indoor and outdoor conditions for an entire year is carried out by using Carrier Hourly Analysis Program software for cooling load estimation, and the Net Present Worth Analysis for Economic Analysis of both systems. Both systems are direct expansion air conditioning systems; hence the cooling load estimation was done using the ASHRAE transfer function method embedded within the Carrier software. Equipment to be used in analysis were selected from the Toshiba selection catalogues (Mini Split system), while that for the VRF system was selected using Toshiba simulation software. The annual energy analysis of both systems indicated that the VRF system will require more energy to run on an annual basis than the Mini Split system. However, the analysis was carried out without considering the part load potential energy savings of the VRF system. Net Present Worth Analysis carried out also favoured the Mini Split system in terms of Net Present Value of the systems. Based on the Engineering Economic Analysis carried out on the two systems, the overall Net Present Value for the VRF system is N77,891,808.66, while that of the Mini-Split system is N46,641,828.74. This result shows that the VRF system has a higher cost implication than the Mini-Split system. Hence, in terms of cost, the Mini-Split system is a more viable option.

An E-Business System Development and Modernization Model to Improve the Profitability of Investment Decisions

An Internet-based Systems Development and Modernization Model (SDMM) is an information technology (IT) method that system designers and developers (SD&Ds) can use to develop new systems, to modernize legacy systems, and to increase the net present worth of the systems. The SDMM is, therefore, implemented for three primary purposes: to design and develop leading-edge technology systems, to modernize legacy systems, and to increase profitability of the systems. The model satisfies SD&Ds’ specifications as well as user requirements from the concept phase to the operational phase of the development process. It is a structured approach through which users and SD&Ds interact before the system is designed; thus, the users can affect system development when it is most cost-effective to do so. The model uses online modules to develop products that are fully capable of bridging the design to the system development lifecycle phases. The SDMM implements IT principles to standardize system development throughout its lifecycle phases.
