SISTEM PAKAR IDENTIFIKASI PENYAKIT KULIT ACNE VULGARIS MENGGUNAKAN METODE DEMPSTER SHAFERER

Acne vulgaris is a common skin disease caused by clogged pores due to blockage from excessive oil glands and piles of dead skin cells, causing the initial appearance of acne, namely blackheads, which can then develop into more severe festering. These types of acne are categorized into mild, moderate, and severe acne. The low level of awareness for acne sufferers is caused by a lack of knowledge about acne and limited costs for consulting a skin expert or beautician to get the right facial treatment. For this reason, an expert system is presented to help ordinary people deal with skin diseases, especially acne vulgaris, quickly and precisely. The expert system was built using the Dempster-Shafer method in carrying out the reasoning process to find a conclusion from the facts that exist. The accuracy results obtained by comparing the results of the system diagnosis with the results of diagnoses made by experts on 115 acne vulgaris disease data obtained an accuracy value of 94%.
