Tujuan penelitian ini adalah mensintesis biodiesel dari minyak nyamplung melalui proses esterifikasi dan transesterifikasi dengan bantuan ozonisasi dan gelombang ultrasonik. Ozonisasi dilakukan selama 30 menit, sedangkan reaksi transesterifikasi dibantu dengan gelombang ultrasonik pada variasi frekuensi 28 dan 35 kHz masing-masing selama 30 menit. Hasil penelitian menunjukkan bahwa penggunaan gelombang ultrasonik dengan frekuensi 35 kHz pada reaksi transesterifikasi terhadap minyak nyamplung terozonisasi dari reaksi esterifikasi dihasilkan biodiesel yang relatif sesuai dengan standar biodiesel Indonesia. Biodiesel yang dihasilkan pada kondisi tersebut memiliki bilangan asam 0,70 mgKOH/g biodiesel, bilangan iodium 50,34 g I2/100 g, titik nyala 122,4°C, bilangan cetana 102,5, densitas 0,9088 g/cm3, dan viskositas 9,5 cSt.(BIODIESEL SYNTHESIS THROUGH NYAMPLUNG OIL ESTERIFICATION AND TRANSESTERIFICATION USING ULTRASONIC WAVES ASSIST)This study was aimed at synthesizing biodiesel of nyamplung oil through esterification and transesterification process using ozonation and ultrasonic waves assist. The ozonation was done for 30 minutes, while the transesterification reaction was aided by ultrasonic wave frequency variation 28 and 35 kHz for 30 minutes. The results show that the use of ultrasonic waves in frequency of 35 kHz in the transesterification reaction to the ozonized nyamplung oil from esterification reaction produced biodiesel on the standards of Indonesian biodiesel. The biodiesel product in this study has 0.70 mgKOH/g biodiesel acid value, iodine number 50.34 g I2/100 g, the flash point of 122.4°C, cetana numbers of 102.5, density of 0.9088 g/cm3, and a viscosity of 9.5 cSt
