Kualitas hasil pemotongan kayu merupakan salah satu faktor penting dalam industri pengolahan kayu karena berpengaruh terhadap kualitas produk akhir dan efisiensi proses produksi. Penelitian ini bertujuan untuk menganalisis pengaruh desain mata pisau terhadap kehalusan dan kerataan permukaan hasil pemotongan kayu walnut menggunakan mesin ripsaw, sejalan dengan kajian desain mata gergaji bundar pada proses pemotongan kayu[1]. Penelitian dilakukan dengan menggunakan tiga variasi desain mata pisau yaitu M1, M2, dan M3. Parameter kualitas permukaan diukur menggunakan Surface Roughness Tester dengan indikator nilai kekasaran permukaan (Ra). Setiap perlakuan dilakukan sebanyak 15 kali pengujian. Hasil penelitian menunjukkan bahwa nilai rata-rata kekasaran permukaan pada mata pisau M1 sebesar 4,03 µm, mata pisau M2 sebesar 3,91 µm, dan mata pisau M3 sebesar 3,20 µm. Nilai kekasaran terendah diperoleh pada mata pisau M3 yang menunjukkan kualitas permukaan paling halus. Hasil analisis menunjukkan bahwa desain mata pisau memengaruhi kualitas hasil pemotongan kayu walnut secara deskriptif, dimana mata pisau dengan jumlah gigi lebih banyak menghasilkan permukaan yang lebih halus dan rata. Penelitian ini memberikan rekomendasi penggunaan mata pisau M3 untuk meningkatkan kualitas hasil pemotongan kayu walnut pada mesin ripsaw
