Persamaan gerak osilasi pegas dengan massa berubah terhadap waktu merupakan persamaan differensial non linear yang sulit diselesaikan secara analitik. Pada penelitian ini persamaan gerak osilasi tersebut diselesaikan menggunakan metode Runge Kutta orde empat dan Runge Kutta Fehlberg tingkat lima. Metode Runge Kutta menawarkan penyelesaian persamaan diferensial dengan pertumbuhan truncation error yang jauh lebih kecil. Hasilnya menunjukan gerak osilator dengan massa yang terus berkurang terhadap waktu memiliki sifat seperti osilator teredam dan menjadi gerak harmonik sederhana saat massa osilator tetap. Metode Runge Kutta orde empat dan Runge Kutta Fehlberg mampu menggambarkan keadaan sistem osilator dengan massa berubah terhadap waktu.
