Post is one element of the fixed restorations that is generally used to restore endodontically treated teeth at Prosthodontic Installation of Oral and Dental Hospital (RSGM) Faculty of Dentistry Universitas Padjadjaran, whereas Orden alloy is still used as cast post material. The faculty supplies Orden without packaging or manuals, so the information about its composition and mechanical properties are not available. This study was conducted to search the composition, tensile strength, and elastic modulus of Orden. For the composition test, a specimen with size 20x20x2 mm3 was tested with Optical Emission Spectroscopy (OES). For tensile test, 6 specimens were made according to ASTM Standard E8. While for bending test, 6 specimens were made according to ASTM Standard E855. The Universal Testing Machine Instron 1195 was used to test the tensile strength and elastic modulus. The value of tensile strength of Orden was compared to gold alloy type III and the value of elastic modulus of Orden was compared to dentin. Composition test found that Orden was a brass with the largest ingredient of copper 53.76 wt%, followed by zinc 44.94 wt%, and aluminum 1.17 wt%. The statistic calculation showed that tensile strength of Orden was lower than gold alloy type III and the elastic modulus of Orden was higher than dentin.

The advancement of digital technology has accelerated media convergence, integrating traditional and digital media into a unified and interconnected communication ecosystem. This phenomenon not only transforms the distribution of information but also reshapes how individuals think, interact, and construct their identities, particularly among Generation Z. This study aims to explore the meaning of media convergence from the perspective of Generation Z students at the State Islamic University of North Sumatra (UIN Sumatera Utara). Employing a descriptive qualitative approach, data were collected through semi-structured interviews with five informants selected via purposive sampling. The findings reveal that students perceive media convergence as a new normal embedded in their daily lives. Digital media are viewed not merely as tools but as integral spaces for learning, self-expression, and social interaction. Four major themes emerged: efficiency and accessibility of information, digital lifestyle transformation, creative and identity expression, and awareness of ethical digital challenges. The novelty of this study lies in its focus on the subjective experiences of students within a faith-based higher education setting. These findings enrich the discourse on digital literacy and offer strategic implications for educational institutions in cultivating a generation that is adaptive, critical, and ethically responsible in navigating the digital media landscape.
