The problems that exist in the Nagari IV Koto Aur Malintang farmer group can be overcome by researchers in the form of an expert system design for diagnosing maize pests and diseases that are applied directly to the Nagari IV Koto Aur Malintang farmer group using PHP as a system developer media and a MySQL database that can store data. data properly and securely. From the explanation above, the author makes a system, namely an expert system for diagnosing corn pests and diseases using the certainty factor method, which is very suitable for an expert system that diagnoses something that is uncertain.
