Sistem Pakar Diagnosa Penyakit Anak Menggunakan Metode Certainty Factor

Abstract

Children’s health is a crucial aspect that requires special attention because a child’s immune system is not yet fully developed, making them more vulnerable to various illnesses. In many cases, parents are unable to identify early disease symptoms promptly due to limited medical knowledge, time constraints, or restricted access to healthcare professionals. To address this issue, an expert system is designed to assist parents in diagnosing children’s diseases based on observable symptoms. This system provides practical support by offering preliminary diagnostic guidance, thereby helping parents take early and appropriate action. The expert system applies the Certainty Factor method, which is used to manage the level of uncertainty commonly encountered in medical decision-making. This method assigns a degree of confidence to the relationship between specific symptoms and possible diseases. The certainty values are derived from expert knowledge and updated medical information provided by healthcare professionals. As a result, the system is able to deliver more reliable and informative diagnostic recommendations, supporting parents in making better health-related decisions for their children.
