40th PSDIT Doctoral Promotion
Doctoral Study Program in Engineering Sciences (PSDIT), Faculty of Engineering, Udayana University held a doctoral promotion section on Thursday, March 24, 2022 at 10.00 WITA located in the Wiswakarma Hall of Udayana University for promovendus I Made Rajendra. His dissertation entitled Pyrolysis of Fixed Bed Using Iron Sand Bed Materials, Mordenite and ZSM-5 for Conversion of Hazelnut Sunan Dregs Biomass into Biodiesel Raw Material. I Made Rajendra successfully defended his dissertation and graduated with a very satisfactory. 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 is rich in natural resources and has various sources of renewable energy derived from biomass, one of which has the potential as raw material for biodiesel, Hazelnut Sunan. The Hazelnut Sunan biodiesel production process will leave waste in the form of dregs of Hazelnut Sunan. The Hazelnut Sunan 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.
The session was chaired by the Dean of the Faculty of Engineering, Udayana University, Ir. I Ketut Sudarsana, S.T., Ph.D.. Meanwhile, Prof. I Nyoman Suprapta Winaya, S.T., M.A.Sc., Ph.D., Dr. Ir.
