Abstract

The demand of food is continuously increasing as compared to its production due to the rapid urbanization, population growth and climate change. In this scenario, greenhouse is an alternative to maximize the food production without increasing fertile land. The smart greenhouse uses integrated sensor system to control and monitor the environment inside the greenhouse. This research focuses on designing cost effective and automatic parameter monitoring system for existing greenhouses using microcontroller. The research was carried out in two parts, initially, feedbacks regarding the current greenhouse and scopes for automation were collected through field survey with the farmers and later, an experimental model was developed in accordance with the data collection. From the data analysis of field survey, it was found that current greenhouses had problems in effective temperature and irrigation control. Thus, the designed model carries out automatic cooling and irrigation with effective monitoring of this parameter in a display. Furthermore, upon economic analysis, labor cost for monitoring of greenhouse was Rs. 1, 66,860per annum which will be reduced. Meanwhile, discounted payback period analysis showed that initial investment will recover after 2.34 years with the cost for conversion to smart greenhouse at Rs 552 sq. meters.

Abstract

The existing national grid network is unreliable in providing power to the rural hilly areas due to difficult to geographical structure of Nepal. Therefore, the demand ofMicro-hydro power plants are increasing in these areas of Nepal. MHPs produces up to 100kW and helps to distribute power to isolated communities. The main objective of this research is to study the technical and economic feasibility of micro hydropower in Gairibari Jharna, Kalika Municipality-08, Chitwan, Nepal.This project is an explanatory type research which is based on the primary data collected through questionnaires and field survey. Furthermore, upon the analysis of data collected from 41 out of 87 households, it showed positive interpretations.Through the qualitative and quantitative research, average power demand for each household was found to be 513.29 W leading to an average energy demand of 1.9 kWhr per day. Meanwhile, technical calculations showed the head available to be98m, discharge produced to be 0.24221m3/s and the ultimate design reflected the generated power to be 12 KW. Through the detail analysis of cost, budget for this projectwas NepaleseNRs 36,84,730 ($ 28,102.7) . After economic analysis of cost the payback period is calculated to be 15.37 years.
