43rd Doctoral Promotion

Doctoral Study Program in Engineering (PSDIT) Faculty of Engineering, Udayana University on Tuesday 27 September 2022, 10:00 WITA at the Wiswakarma Hall, Udayana University, held the 43rd doctoral promotion session. Promovenda Ni Kadek Astariani with a dissertation title Utilization of Slate Stone Powder as Precursor for the Manufacture of Geopolymer Binder. The promovenda study period is 3 years and 1 month and is declared to have passed with a very satisfactory predicate.

Dr. Ir. Ni Kadek Astariani, ST., MT., IPM in her presentation said that Portland cement as a concrete-forming material in its production requires a very large amount of energy and releases large amounts of CO2 gas into the air. This of course has a negative impact on the environment. Therefore, efforts are made to reduce cement in the manufacture of concrete. Meanwhile, geopolymer binder is a geosynthetic adhesive that uses materials that are not derived from cement. In this study, slate stone waste will be processed into powder which is used as a precursor in the manufacture of geopolymer binder. The results showed that geopolymer binder with slate stone powder as a precursor can be considered as a binder substitute for cement for non-structural components.

Acting as the chair of the session was the Deputy Dean of Academic Affair of the Faculty of Engineering, Udayana University, Prof. I Nyoman Suprapta Winaya, ST., MASc., PhD. As the promoter is Prof. Dr. Ir. I Made Alit Karyawan Salain, DEA, co-promoters I and II are Prof. Dr. Ir. I Nyoman Sutarja, MS and Ida Bagus Rai Widiarsa, ST., MASc, Ph.D respectively. Acting as the internal examiners are Prof. Ir. I Nyoman Arya Thanaya, ME., PhD., Prof. Dr. Ir Ngakan Made Anom Wiryasa, MT., IPM., Prof. Dewa Made Priyantha Wedagama, ST., MT., MSc., Ph.D, Ir. Ida Ayu Made Budiwati, MSc., Ph.D, Dr. Ir. Yenni Ciawi and Gede Pringgana, ST., MT., Ph.D. There were three academic invitees consisting of Dr. Ir. Ngakan Ketut Acwin Dwijendra, ST, SDs, MA, IPU, ASEAN Eng, ., Dr. Ir. I Gusti Lanang Bagus Eratodi., Dr. Ir. I Wayan Parwata, MT., IPU. ASEAN. Eng.
