Abstract

The objectives of this research were to (1) determine the production and quality of chrysanthemum on frequency (amount of exposure per day) and duration of electromagnetic field exposure during generative phase, (2) determine frequency and duration of electromagnetic field exposure which produce the best production and quality of chrysanthemum flower. The method of this research was experimental method with two treatments.The first treatment was frequency of electromagnetic field exposure consisted of 1, 2 and 3 times per day and second treatment was electromagnetic field exposure duration consisted of 5, 20, and 35 minutes. Variables which measured for flower production were age of plant that started to blooming, harvest age, amount of flower and amount flower of half blooming, while for quality were diameter of flower, flower color, weight flower, and flower resistance after harvest. Result showed that production and quality of chrysanthemum was low, if electromagnetic field exposure at 3 mT (militesla) with frequency exposure 1, 2 and 3 times per days and duration exposure was 5, 20, and 35 minutes in generative phase. The best treatment contained in frequency 2 time per day and exposure duration 5 minutes gave the best result for production and quality of chrysanthemum flower.

Abstract

The purposes of this research were to observe the role of electromagnetic field exposure on vegetative phase to spur the growth of Chrysanthemum plants and to determine the appropriate electromagnetic field strength and frequency of exposure that resulted the best growth of chrysantemum plants. The method of this research was descriptive analysis with two treatment. The first treatments was electromagnetic strength consist of 2 mT (B1), 3 mT (B2), and 4 mT (B3). The second treatment was frequency of electromagnetic field exposure, consist of 1 (F1), 2 (F2), and 3 (F3) times per day. In this research, the control was without exposure by electromagnetic field used as a comparision and. Variables measured were phase were root length, rod diameter, plant height, amount of leave, and plant canopy. The result showed that plant which exposured by 2 mT until 3 mT electromagnetic field 2 times per day had a good impact for vegetative growth, however for more than 3 mT, gave unstatisfactory impact. Plant with the best vegetative growth results were exposured by 3 mT electromagnetic field 2 times per day or B2F2

Abstract

The aims of this research were to develop image processing algorithm that can be used for rice yield estimation. This research consist of: 1) image acquisition, 2) image analysis with Adobe Photoshop Cs 4 and MATLAB R2009B, and 3) make the algorithm that suitable for rice yield estimation. This research was testing three method of image processing, i.e. manual pre-processing, thresholding method, and shape of Structuring Elements (SE). Forming algorithm was done by analyzing image yield and be compare with real image. More like image yield with real image, then this method was suitable for doing rice image analysis. The result of analysis showed that process of rice image analysis have to be started with manual pre-processing, using custom thresholding method, and morphology with SE shape disk. The result image of the algorithm showed the most appropriate grain image with real image, and there’s no more image that identified as a grain. Based on number of pixel, the image yield of this method is 117.407 pixel. In conclusion, the algorithm for estimation of rice yield, consist of: image acquisition, manual pre-processing, gray scaling, thresholding custom, morphology with SE shape disk, image resize, and calculation of the number of pixel grain.
