Abstract


The livelihoods of most people in Indonesia are cultivate rice which is the staple food for the people of Indonesia. The productivity of rice plants can be obstructed when rice attacks disease. Diseases can be addressed from young if farmers know how to handle it.

The output is obtained from the results of the consultations that conducted by user. Users must answer the questions in the form of symptoms of the disease. In the design of this applications making by using the PHP programming and used a MySQL database. Applications make based on the WEB.
