Abstract: Necessity of fuel
are increasing rapidly nowadays. But oil is an irreversible product, so it is required
to look for other alternative fuels, especially from renewable materials.
Currently being developed technology that uses biodiesel as renewable
alternative fuel. The aim of this research to determine whether oil and seaweed
Eucheuma denticulatum and Lemuru fish oil can be used as materials for
biodiesel.
This research was conducted by observing and comparing the flash point,
freeze point, and viscosity of each treatments. The Method in this research is
experimental method and supported by panelist. There were 9 treatments in this
study, there are P0 (Biodiesel commercial), P1 (Biodiesel Eucheuma denticulatum
100 %), P2 (Biodiesel Eucheuma denticulatum 75% + Biodiesel commercial 25%), P3
(Biodiesel Eucheuma denticulatum 50% + Biodiesel commercial 50%), P4 (Biodiesel
Eucheuma denticulatum 25% + Biodiesel commercial 75%), P5 (Biodiesel Sardinella
oil 100 %), P6 (Biodiesel Sardinella oil 75% + Biodiesel commercial 25%), P7
(Biodiesel Sardinella oil 50% + Biodiesel commercial 50%), and P8 (Biodiesel
Sardinella oil 25% + Biodiesel commercial 75%). Each treatments was repeated 3
times. The main parameter observed was flash point, freeze point, and viscosity
in every treatment. The data analysis used was non-parametric test with
Friedman test and continued with Wilcoxon test.
The results of this study indicate that the best of the nine treatments
is P8 which is a mixture of lemuru fish oil biodiesel 25% and 75% biodiesel
with the specifications freezing point -3 o C, viscosity of 4.02 mm2 / s, and
the flash point of 47.9oC.
