The Study Program of Doctoral Engineering Sciences (PSDIT) held its 54th Doctoral promotion on Monday, August 21, 2023, at Wiswakamma Hall, Faculty of Engineering, Udayana University. Promovendus I Made Astika, ST., M.Erg., MT, with a dissertation entitled Improvement of Thermal and Mechanical Performance of Phase Change Material (PCM) Composites from Beef Tallow using Rice Husk Charcoal completed his research for 4 years and 1 month and received a very satisfactory predicate.
In his presentation, Dr. I Made Astika, ST., M.Erg., MT described that there has been an increased emphasis on using materials capable of absorbing and storing heat as alternative energy storage in buildings. Phase Change Materials (PCMs) demonstrate this capability, harnessing the latent heat principle to absorb surplus heat energy and subsequently release it in times of deficiency. It is necessary, therefore, to examine the mechanical and thermal properties of wall cladding materials integrated with PCMs, specifically beef tallow and rice husk charcoal. The study found that beef-tallow PCM exhibits promising potential as a heat storage system for buildings, contributing to energy conservation in the construction industry
