Abstract

Kinetics parameter is required to determine the production of biodiesel in certain circumstances. This study aims at determining the kinetics parameters of biodiesel production through transesterification assisted by microwaves. This research was conducted using used cooking oil derived from street vendors of fried around the University of Lampung. The chemicals used are methanol (technical) and NaOH (pa). The study was conducted with a molar ratio of 1: 4 and with a combination of three levels of temperature (45°C, 50°C and 55°C) and a five-level of reaction time (2 minutes, 3 minutes, 4 minutes, and 5 minutes). Results showed that the highest biodiesel yield amounted to 66.8% at the time of 6 minutes and a temperature of 55°C. The result of the calculation produces the value of the reaction rate constant (k), which increases with temperature, ie. 0.0609 per minute at a temperature of 45°C, 0.047 per minute at 50°C, and 0.0291 per minute at 55°C. The calculation resulted that the value of activation energy (Ea) of 63.94 kJ/mol with a value for the collision frequency constant (A) was 8.38(109) per second.
