Abstract
Baja merupakan perpaduan antara besi, karbon dan unsur lainnya. Pengaplikasian baja diatur oleh International Organization of Standardization (ISO) seperti ISO 4948 yang mengatur klasifikasi jenis baja berdasarkan komposisi kimianya dan ISO 8503 yang mengatur tingkat kekasaran permukaan baja. Pengaplikasian baja di beberapa material memerlukan tingkat kekasaran yang berbeda. Pengklasifikasian kekasaran permukaan baja diperlukan untuk meningkatkan efisiensi dan memperpanjang umur penggunaan material berbahan baja. Oleh karena itu, pengklasifikasian tingkat kekasaran permukaan baja menjadi penting. Penelitian ini bertujuan untuk mengklasifikasi tingkat kekasaran permukaan baja dengan menggunakan metode Fuzzy Naïve Bayes. Fungsi keanggotaan Fuzzy yang digunakan dalam penelitian ini adalah kurva linier naik, kurva linier turun, dan kurva trapesium. Klasifikasi dengan menggunakan metode Fuzzy Naïve Bayes menghasilkan nilai ketepatan yaitu, nilai Accuracy sebesar 91,67%, Presicion sebesar 51,52%, Recall sebesar 45,38%, Specificity sebesar 93,18% dan Fscore sebesar 48,26%.
