Expert system for disease diagnosis in cocoa plant using android-based forward chaining method

Abstract

Abstract Cocoa is one of the plantation crops that has high economic value besides it can also provide a large contribution so that it can increase the source of foreign exchange in Indonesia. This expert system is made for Android device users. In 2010 Indonesia succeeded in occupying the number three position after Ghana and Ivory Coast as the largest cocoa producer in the world. But the amount of cocoa production in West Sumatra has decreased due to a lack of knowledge of farmers in caring for and cultivating it. This is the background of this research, where this expert system uses the Forward Chaining method as a symptom search method that has been included as a tracking algorithm for each rule that has been set. So that it can produce an expert system for diagnosing cocoa plants that are right for farmers. When conducting a consultation, the user can answer Yes or No from the question given by the system. User answers are then processed based on rules and calculated using the forward chaining method. Testing is done to see if the system can run well as expected.
