Abstract :
Rabbits are mammals from the Leporiade family which are easily found all over the world, including in Indonesia. Many people keep rabbits for various purposes one of them is farmed. Many people raise rabbits for business because the results are promising. Even though the rabbit business is promising, it doesn't mean it doesn't have problems. there are many obstacles encountered by rabbit breeders who are members of the rabbit community in Probolinggo. Some of the obstacles that cannot be overcome, such as the lack of education about the disease and its solutions to rabbit farmers, cause losses for farmers. Based on these problems, the author tries to build an expert system for diagnosing rabbit disease which is implemented on a website-based application. This expert system is expected to be able to help rabbit farmers to diagnose rabbit diseases without having to go to the vet.
