“…The data showed that the average temperatures and humidity were 28,07 ± 2,25 °C and 93,89 ± 7,06% [10]. An important environmental requirement during the cropping of mushrooms is that the evaporating power of the air circulating over the beds should lie within specified limits [9].…”

This study aims to improve the productivity and flexibility of the mushroom house to increase the production of straw mushrooms. Determining the design of technical specifications and material requirements of the mushroom house is a process that is quite important in determining the success or failure of increasing straw mushroom production. QFD (Quality Function Deployment) is used to obtain the best design based on the needs of the mushroom farmers. The needs of the mushroom farmers are then translated through QFD into technical specifications. MCDM (Multi Criteria Decision Making) is used to determine the material for the frame and blanket of the mushroom house according to the technical specifications of the QFD. CRITIC (Criteria Importance Through Intercriteria Correlation) is one of the methods of MCDM that performs an objective weighting of the criteria. A mushroom house was built based on the technical and material specifications obtained from QFD and CRITIC. Tests were carried out by comparing the productivity and flexibility between traditional mushroom houses and designed mushroom houses. The peroductivity of the mushroom house includes cleanliness, stability in temperature and humidity, the rate of growth of straw mushrooms in media. Flexibility includes the ability to assembled and disassembled, easily mobilize from one place to another.

“…This means that for the same amount of compost, a larger building is required, which increases the investment costs. The air supplied through the duct can be adjusted more easily to achieve a uniform temperature distribution (Bowman, 1991;Han et al, 2009). Further investigation is required regarding the effects of mushroom compost on the air pressure drop.…”

Shiitake (Lentinula edodes) is one of the most cultivated mushrooms in the world, and it prefers a temperate climate. The improvement of warm-weather shiitake strains is one way to increase shiitake yield in Thailand. Mushroom-growing houses should be equipped with mechanical cooling to control and establish the optimal environment for cultivation. In this study, an Indirect-Direct Evaporative Cooling (IDEC) system consisting of a cooling coil and evaporative cooling (cellulose pad) was tested for its suitability for shiitake cultivation from August 2020 to December 2020. Under optimal shading of, and growing conditions, the IDEC system maintained the air temperature (27-28°C) and relative humidity in the required ranges. The mushroom compost was almost completely brown after the 100-day test and ready for the next fruiting phase. When compared with the fan-pad system, regression analysis showed that the two systems exhibited similar performance and had similar equipment costs. However, the IDEC system had a lower air temperature at a lower relative humidity, and its efficiency was over 100%. This study demonstrated that the IDEC system can be applied to promote shiitake cultivation in hot and humid climates.
