Abstract. Hirota bilinear operator (Hirota Method) is proposed to directly construct periodic wave solutions from Korteweg de Vries (KdV) equation. This solution can be expressed in terms of Jacobi Theta 4 (Θ4) functions, with dispersion relation yielded from degradation of biliear equation. Then, sinusoidal wave, Solitary, and Cnoidal can be reduced from this solution to asses certain of nome (q).Key words: Hirota Bilinear operator, Korteweg de Vries (KdV) equation, periodic profil gelombang khusus seperti gelombangCnoidal dan Solitary.Permalink : http://ejournal.undip.ac.id/index.php/sm/article/view/2962
