ABSTRACT
The increased energy needs of fossil fuels in particular leads to a decline in the
world’s oil reserves which make this extremely rare. One way to reduce the
energy crisis and the impact that fossil-funded energy use can have is to develop
new and renewable energies such as vegetable fuels. One of the alternative forms
of energy currently being developed is biodiesel. Biodiesel is one of the
environmentally friendly alternative to diesel fuel. This research studied the effect
of agitation speed with variations 300 rpm, 400 rpm 500 rpm, metal that falls into
clay with variations 1%, 3%, 5% and activation NaOH with variation 1N, 2N and
3N to the yield biodiesel produced, and to indentifying the characterictics of
biodiesel produced. This study begins impregnation of La metal into clay, the
La/clay catalyst is calcination for 6 hours at 500oC with N2 gas, oxidation for 2
hours at 400oC with O2 gas and reduction for 2 hours at 400oC with H2 gas. After
that, do the process of esterification in the flat bed reactor the temperature reaction
60 oC and reaction time 60 minutes, and then process of transesterification with
temperature reaction 60 oC, reaction time 90 minutes, ratio mole oil : methanol
1/9, and catalyst weight 3 % (w/w) oil. Highest biodiesel yield obtained amounted
to 89,78 % at the agitation speed 400 rpm and metals La(5%)/clay activation
NaOH 3N. Physical characterization of biodiesel were done such as density 884
kg/m3, kinematic viscosity 5.54 mm2/s, acid number 0.676 mg-KOH/g biodiesel
and flash point 139 oC respectively which have accordance with the standards of
Indonesian biodiesel (SNI 04-7128-2015).
Keywords: BBN, biodiesel, esterification, La/Clay catalyst, transesterification
