Dempster-Shafer Method for Diagnose Diseases on Vegetable

In this discussion will be described the types of diseases that often attack vegetable crops. In contrast to vegetable pests that can be known from the vision of the type of pest than the impact of the attack. The organism that causes plant disease is very small (micro), so by lay farmers can only be known from the impact of the attack. Therefore, the understanding of environmental factors that influence the rapid development of disease-causing organisms, the characteristics of the symptoms of attack of the types of diseases, and the way of breeding is very important to know. To that end, the dempster shafer method produces a variety of symptoms, causes, solutions and diagnostic results based on a knowledge base for evidence based on belief functions and plasible reasoning, used to combine separate pieces of information (evidence) for calculate the probability of an event. Begin by calculating the belief value, calculating the probability of the density function (m), calculating the combined function value of m (Z), then the data is reprocessed based on the knowledge base of experts who are experts in the field of agricultural technology. From the case occurring and experiencing a process named test cases that have been done on vegetable crops, the results of an accurate assay is 90% indicating that the application of the application performed with a method works well in accordance with Dempster-Shafer.
