Abstract

This research was describe about temperature profile on Arch Greenhouse with the curved shape of roof and square wall for Chrysanthemum (Chrysanthemum morifolium) that cultivated on Arch Greenhouse. The aims of this research were to obtain a temperature profile on arch greenhouse, to determine the building height of arch greenhouse which suit for chrysanthemum cultivation. Height treatments of greenhouse was separated by 3 levels i.e. 2.5 m, 3.0 m, and 3.5 m. Chrysanthemum seeds varietys used in this research was Fiji white. To measure the temperature used temperature and humidity meter. Temperature measurement carried out by 2 times start from a week before planting (empty condition) and plant age was 45 days after planting. Doing the measurement on morning, noon, and afternoon. Analysis data of temperature was done with interpolation to determine profile contour line of analysis temperature. The result showed that there are the different shape and contours distribution profile of microclimate for difference height. The level of growth plan on each treatments showed a better productivity on greenhouse with height 2.5 m when compared with the others. Greenhouse with height 2.5 m produced flower quality which suit as the SNI with average of height plan was 81.93 cm, grooming age was 46 days, amount flower was 5 florets per stem, flower wide was 44.26 cm, and dry weight was 13.11 gram.

Abstract

This research was carried out to know the result of the application method system of rice intensification (SRI) which was combined with rice planting system legowo in raw toward micro climate which influence the productivity of red rice. These research was consist of 6 treatments, they were : K0 (the treatment which appropriated to local farmers custom), K1 (SRI method), K2 (SRI method combined with legowo 4:1 inserting), K3 (SRI method combined with legowo 4:1 without inserting), K4 (SRI method combined with legowo 6:1 inserting), and K5 (SRI method with legowo 6:1 without inserting). This treatment study was repeated 3 times. Parameters observed were : relativity of humidity, temperature, intensity of sun shine, the length of stalk, the weight of rice in a clump, percentage pure rice, the weight of 1000 pure rice, the number of young plants in a clump, the number of young plants and each productivity. The outcome of this research shown that the application of SRI method combined with legowo 4:1 without inserting got more intensity of sun shine and the highest temperature, while the application of K0 had the highest relativity weakness. Application SRI method with legowo 6:1 without inserting produced the highest product in average per width of area, there were 7,48 ton/ ha, comparing with other applications.
