The 40th Open Examination of Doctoral Promotion in Engineering Faculty
Doctoral
Study Program in Engineering Sciences (PSDIT) Faculty of Engineering, Udayana
University on Thursday, March 24, 2022, at 10.00 WITA located in the Wiswakarma
Hall of Udayana University, conducting an open examination (Doctoral
promotion). Promovendus on behalf of I Made Rajendra with a dissertation title
"Pyrolysis of Fixed Bed Using Bed Materials Iron Sand, Mordenite and ZSM-5
for Conversion of Sunan Candlenut Cake Biomass into Biodiesel Raw
Material". Promovendus passed with a very satisfactory predicate. Dr. I
Made Rajendra is the 40th graduate of PSDIT.
Dr.
I Made Rajendra in his presentation explained that the issue of fossil energy
scarcity has now become the concern of all parties. The Indonesian government
has scheduled an energy transition program from fossil energy sources to new
and renewable energy (EBT). Indonesia as a country rich in natural resources
has various sources of renewable energy derived from biomass, one of which has
the potential as raw material for biodiesel, that is Kemiri Sunan (Reutalis
trisperma (blanco) airy shaw). The Kemiri Sunan biodiesel production process
will leave waste in the form of dregs or Kemiri Sunan cake. The cake waste can
still be processed into bio-oil through the pyrolysis technique. The
effectiveness of pyrolysis is influenced by temperature parameters and the use
of bed materials that play a role in product selectivity, especially the
formation of hydrocarbon compounds in bio-oil. Up-to-date bed materials such as
the ZSM-5 are currently still expensive and have not been produced
domestically. The innovation in this research is to apply the use of iron sand
as an alternative material. The results showed that the pyrolysis oil produced
had met the requirements as biodiesel feedstock.
