Penelitian ini bertujuan mempelajari kelakuan dinamika proses transesterifikasi dari minyak goreng bekas berbantukan gelombang ultrasonik. Persamaan kinetika reaksi transesterifikasi diperoleh dari penelitian Aulia, et al (2012). Reaksi dijalankan dalam Reaktor Tangki Berpengaduk Aliran Kontinyu (CSTR), dimana reaktor ini memainkan peranan penting dalam industri kimia. Proses simulasi dilakukan dengan menggunakan perangkat lunak SIMULINK-MATLAB. Dinamika yang dipelajari meliputi konsentrasi reaktan, produk dan temperatur. Dinamika konsentrasi meliputi minyak, metanol, biodiesel ,dan gliserol. Dinamika temperatur meliputi temperatur reaktor dan pendingin. Dari hasil penelitian menunjukan bahwa semakin tinggi konsentrasi awal umpan minyak semakin cepat waktu mencapai steady state pada produk biodiesel. Semakin tinggi temperatur awal reaktor semakin cepat waktu untuk mencapai steady state. Waktu untuk mencapai steady state pada jaket pendingin tidak dipengaruhi kondisi suhu awal reaktor. ÂKata kunci: dinamika, transesterifikasi, ultrasonic, konsentrasi umpan, temperature umpan, simulink
