Kekasaran permukaan merupakan salah satu parameter penting yang menentukan kualitas hasil pemotongan pada proses manufaktur. Penelitian ini bertujuan untuk menganalisis pengaruh ketebalan material dan kecepatan pemotongan terhadap kekasaran permukaan baja karbon AH36 menggunakan mesin CNC plasma cutting. Metode yang digunakan adalah metode eksperimen dengan variasi ketebalan material dan kecepatan pemotongan sebagai variabel bebas serta kekasaran permukaan sebagai variabel terikat. Data dianalisis menggunakan uji normalitas Kolmogorov-Smirnov, uji homogenitas, Two-Way ANOVA, dan uji lanjut Post Hoc. Hasil penelitian menunjukkan bahwa ketebalan material berpengaruh signifikan terhadap kekasaran permukaan dengan nilai signifikansi 0,007, sedangkan kecepatan pemotongan berpengaruh signifikan dengan nilai signifikansi 0,000. Interaksi antara ketebalan material dan kecepatan pemotongan tidak berpengaruh signifikan dengan nilai signifikansi 0,602. Uji Post Hoc menunjukkan adanya perbedaan signifikan pada setiap tingkat kecepatan pemotongan. Kecepatan pemotongan merupakan faktor yang paling dominan memengaruhi kekasaran permukaan hasil pemotongan.
