Application of Digital Image Processing to Predict the Diameter of Chrysanthemum Flowers Ready to Harvest

Abstract

Since 1940, chrysanthemum was developed commercially. Potentially, the cut chrysanthemum commodity still has problems in its development. Chrysanthemum flower production scheduling is needed to increase the quantity, quality and continuity of chrysanthemum production according to market demand. This happens because usually managers or entrepreneurs only harvest flowers en masse without seeing some flowers that should not be suitable for harvesting are also cut off. Therefore, it is detrimental to the manager itself and reduces the quality of the chrysanthemum flower products that are sold. The solution to the existing problem is that there is a need to observe flowers by applying precise agricultural technology according to the times to ensure the bloom time. By knowing this phase, the flower harvest period can be predicted correctly so that the fulfillment of market demand can be met appropriately. Observations in this study use digital image processing with the threshold method, which is then used as a basis for predicting the diameter of chrysanthemum flowers ready for harvest, hopefully this will help farmers or chrysanthemum managers to optimize their harvest. The results showed that the data image observation as a whole experienced the percentage of missing data or errors with possible causal factors due to the density of storage traffic, the effect of lighting, humidity and air temperature. In addition, the use of "image processing" to find the diameter of chrysanthemum flowers ready for harvest has succeeded in approaching the actual condition, although it has not been tested in other varieties.
