KARAKTERISTIK BIODIESEL HASIL TRANSESTERIFIKASI MINYAK JELANTAH MENGGUNAKAN TEKNIK KAVITASI HIDRODINAMIK
Abstract: This study
undertakes the transesterification process of used cooking oils that have
undergone a process of esterification. The transesterification process carried
out by reacting methanol and esterified used cooking oil using KOH as catalyst.
Stirring technique used is based on hydrodynamic cavitation. This research aims
to study the characteristics of biodiesel that made from transesterified used
cooking oil with different concentrations of methanol. The concentration of
methanol used consists of 5 (five) level are: 99.9%, 95%, 90%, 80%, and 70%.
The transesterification process using hydrodynamic cavitation technique with a
99.9% concentration of methanol result in biodiesel with characteristics
consistent by Indonesian National Standard (SNI). In this condition, biodiesel
produced 92.93% of the yield which has characteristics of acid number 0.80 mg
KOH / g, total glycerol 0.045%, alkyl ester 99.45%, iodine number 14.92 g
I2/100 g, viscosity 2,35 mm2 / s ,
density 0.87745 g/cm3 and pH value
4.885. Based on research, the concentration of methanol lower than 99.9% not
yet can produce biodiesel from used cooking oil that have characteristics
according to Indonesian National Standard (SNI).
