The Engineering Science Doctoral Study Program held its 54th Doctoral promotion on Monday, August 21 2023, at the 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 Composite Phase Change Material (PCM) from Beef Tallow Using Rice Husk Charcoal completed his research for 4 years 1 month and got the title very satisfying.

In his presentation, Dr. I Made Astika, ST., M.Erg., MT explained that Phase Change Materials (PCMs) are materials that can absorb and store heat energy when there is an excess/surplus and release it when there is a deficit on the basis of the principle of latent heat storage. . Phase-changing materials are widely applied to the building sector in an effort to save energy consumption. The PCM application in plaster layers will be able to absorb and store most of the solar radiation so as to minimize the effects of temperature fluctuations on the inside of the building. Therefore it is necessary to investigate the thermal and mechanical performance of PCM composite plaster which will be applied to building construction as a plaster coating material. This research concludes that PCM composite plaster is suitable for use as a coating for building walls which functions as an absorber and store of heat to reduce indoor temperature fluctuations.
