Analisis Iklim Mikro di Greenhouse dengan Atap Tipe Arch untuk Budidaya Bunga Krisan Potong

This research discusses profile analyzes the microclimate on crop cultivation chrysanthemum (chrysanthemum morifolium) in the arch-type of building greenhouses. The purpose of this study were (1) to obtain a profile picture on greenhouse microclimate with a high arch type different buildings, (2) determine the greenhouse building height that corresponds to the type of arch for the cultivation of chrysanthemum in Candikuning region. High greenhouse treatment can be divided into three levels, namely 2.5 m, 3.0 m and the highest 3.5 m. This study uses the seeds of white chrysanthemum flowers are varieties of Fiji White. To know the description of microclimate, used tool temperature and humidity meter, light meter. Microclimate measurements performed every 7 days starting from the week before planting up old plants 75 days after planting. Measurements were taken at 19 points each greenhouse is treated with a measurement time of morning, afternoon, evening. Microclimate data analysis then calculated the average at each measurement time and subsequently converted in the form of images for interpolation. The interpolation will be obtained through the profile picture of the microclimate. The results showed a high correlation between a building with an overview microclimate profile obtained, shows the level of growth of plants in each treatment. Greenhouse with a height of 2.5 m show the profile picture of the microclimate is more appropriate than the treatment greenhouse 3.0 and 3.5 m high, it is also reinforced by the results of the data rate of the growth of plants in greenhouses treat 2.5 m.
