Abstract :
The population of ducks in Indonesia continues to increase from
year to year, in 2017 it has reached 49,709,000 heads and Indonesia
is in the top five in the world, while China is the country with the
highest duck population. Duck is a very important producer of meat
and eggs in the Asian region, growth and development can progress
rapidly. With the high demand for duck meat and the lack of
understanding of the community and breeders to take appropriate
action on ducks that are affected by the disease so that it can be fatal.
Not only affects ducks, duck disease will also have an impact on
humans if not treated quickly. These problems can be overcome by
the existence of a system that can detect dengue fever early to help
detect the disease early from the symptoms experienced. This study
uses the dempster shafer method, where later this expert system can
help an expert in diagnosing diseases in ducks based on the
symptoms experienced by the user. The dempster shafer method is
used to calculate the accuracy of diagnosis in ducks. From testing
the level of system accuracy, it is known that the accuracy level is
93%. Expert system applications can be used to diagnose diseases
in ducks.
