Judul: Bifurkasi Hopf Pada Sistem Persamaan Van Der Pol Dengan Gaya Luar Yang Periodik
Abstrak: Dalam penelitian terhadap suatu tabung triode tertutup, Van der Pol menemukan suatu model berupa persamaan diferensial tak linear yang selanjutnya dikenal dengan persamaan Van der Pol. Dalam tulisan ini dipelajari persamaan van der Pol tanpa gaya luar dan dengan gaya luar yang berupa fungsi periodik. Dengan pengskalaan waktu diturunkan sistem persamaan Van der Pol yang lebih sederhana yang selanjutnya dianalisis kestabilannya. Dalam bentuk persamaan Van der Pol tanpa gaya luar, eksistensi limit cycle dapat ditunjukkan dengan Teorema Lienard. Sedangkan untuk sistem persamaan Van der Pol yang melibatkan gaya luar yang periodik, eksistensi limit cycle dipengaruhi oleh perubahan nilai parameter tertentu. Untuk beberapa nilai parameter sistem tidak mempunyai limit cycle. Dalam kondisi ini sistem tersebut mempunyai suatu titik tetap yang bersifat sadel. Penentuan eksistensi limit cycle untuk sistem persamaan Van der pol dengan melibatkan gaya luar yang periodik dilakukan dengan bifurkasi Hopf.
