The study and development to design mushroom nursery for installed within the orphanage cultural school (Main 67) Lao PDR. Is a research to promote and develop the production of raw materials for cooking in the school. Consequently the school has a policy to promote plants and raise animals to prepare food for students. But the amount of the produce is not enough to meet the demand for consumption of students. Therefore the researcher has the idea to design a mushroom nursery that is suitable for for installed within the school. Because the cultivation of mushrooms in the nursery is not difficult and still produces all year round. If there is promotion of mushroom cultivation in addition to plants and animals. Will make the school have raw materials that variety and enough for use in cooking for students. Which will result in students eating more complete categories. By the method of conducting the research beginning with the study and analysis of data to find the amount of mushroom cultivation suitable for the consumption needs of students. After that the study and development of the form of mushroom nursery that is suitable for the use and maintenance. Can be easily assembled and installed. Use materials that can be found locally and use a small budget. According to the research the mushroom nursery is a semiautomatic 3.27 x 8 meters consisting of modular system. By using bamboo and plastic mesh as the main material and inside using the method of placing suspended mushroom bags. Suitable for installation in most schools. Since it can be easily assembled and installed with materials that can be purchased locally. It is also easy to use and maintain. This nursey can produce approximately 2400 mushrooms or about 240 kilograms per month. In summary The study and development to design mushroom nursery for installed within the orphanage cultural school (Main 67) Lao PDR. It is the development of vacant spaces within the school to be agricultural areas that will benefit the school in many ways. Both the quantity of produce and nutrition budget and career promotion.

Currently the toy manufacture is beginning to be interested in greenhouse gas or carbon dioxide equivalent release reduction. Because this is one to way to encourage production cost environment trouble and organization image valve efficiently. The receivable standard for evaluation is carbon footprint for Organization CFO. So this research has objective to study opportunity for initiate CFO in Toy Manufacturing plant case study this CFO is able to evaluate energy consumption and GHG release systematically. This can be used to prepare plan of energy consumption reduction management and reduce GHG release of efficiently. This research was study energy consumption and GHG release by using database of 2010 we found that plant case study was released carbon dioxide 8500 tons CO2 carbon dioxide equivalent by calculated into Scope 1 = 1249 tons CO2 Scope 2 = 6948 tons CO2 equivalent and Scope 3 = 304 tons CO2 equivalent. So the result from this research is being uses important information for planning energy consumption reduction and GHG release of sustainable case study.

This paper presents an establishment of a mathematical model to determine the optimal size of heat pipe (thermosyphon) heat exchanger for reduce the inlet air temperature in evaporative cooling system of greenhouse. The condition of a mathematical model is the total length of heat pipe is 1.5 m. A mathematical model will determine the optimal value of evaporator section and condenser section. The range of evaporator length is 0.5 – 1.4 m with an increment of 0.1 m and condenser length is in range of 0.1 – 1.0 m with an increment of 0.1 m. The inlet air temperature in evaporative cooling of greenhouse is depend on ambient temperature about 35 degree Celsius. While the cooling water temperature is 20 degree Celsius. Evaporative pad of evaporative cooling system is 2 m in width and 7 m in length. From the conditions above the optimize results from a mathematical model are as follows: evaporator section length is 0.9 m and condenser section length is 0.6 m moreover it was shown that investment net saving and maximum heat rate are 79.83 Thousand Baht 0.552 Million Baht and 15.6 kW respectively.
