Abstract

The Sedina Ning UCIC program is a new approach in student orientation activities aimed at fostering a culture of knowledge sharing among incoming university students. This initiative emphasizes active participation through a series of educational activities such as group discussions, digital learning simulations, interactive games, and sharing sessions with lecturers and senior students. Implemented using a social constructivist approach, the program consists of three main phases: planning, implementation, and evaluation. Observations during the program indicate a high level of engagement among participants, as well as improved understanding of academic values and the importance of building social relationships within the campus environment. Evaluation through participant feedback also revealed that the program effectively supported students’ adaptation to university life. Based on these outcomes, the program is considered a strong model for orientation activities that integrate educational values with student involvement.

Abstract

Hydrogels represent a promising alternative for plant cultivation, offering excellent water and nutrient retention. This study reports the synthesis and characterization of an agarose-based hydrogel composite enhanced with eggshell powder (ESP). The hydrogel composites were prepared in four agarose-to-ESP ratios: 10:0 (Hyd-ES0), 10:1 (Hyd-ES1), 10:3 (Hyd-ES3), and 10:5 (Hyd-ES5). Fourier-transform infrared spectroscopy (FTIR) analysis revealed minimal peak shifts, indicating no significant chemical modifications. Characteristic ESP peaks were identified in the composite hydrogels, confirming the effective integration of ESP into the agarose matrix. The addition of ESP reduced the decomposition rate of the hydrogels and increased macromolecular stability. Density measurements indicated higher density with increasing ESP concentration, supported by enhanced crystal formation, as evidenced by more intense diffraction peaks in X-ray diffraction (XRD) patterns. Morphological analysis revealed that the porosity of the hydrogel, swelling, and weight-loss tests showed a decline in both properties with higher ESP content. Seed germination experiments demonstrated that stem, root, and leaf growth, as well as fresh and dry weights, were most optimal with the Hyd-ES1 hydrogel composite. Thus, Hyd-ES1 hydrogel exhibits significant potential as a medium for seed germination and plant growth.
