Abstract:
The porang plant (Amorphophallus muelleri Blume) is a type of Indonesian tuber plant
that belongs to the family of Araceae plants. In recent years, the demand for porang in the
world and domestic markets has continued to increase, this has become a public interest
in planting porang because it has quite a large potential opportunity. However, like other
plants, porang cultivation cannot be separated from pests and diseases. Porang farmers
must be able to quickly identify the types of pests and diseases that attack crops to minimize
damage. A quick way that can be used to identify diseases and pests in porang plants is to
use a tool in the form of an expert system. One method that can be used in expert systems
is Dempster-shafer. This method can help in diagnosing diseases and pests based on the
entered symptoms. This study used 3 pest data, 4 disease data, and 22 symptom data on
porang plants. This study involved 2 experts with 12 different case data in the field. The
results of this study are based on a comparison of expert diagnoses with systems, there are
11 appropriate diagnostic data.
