On August 17-18, 2024, PUI-PT Combinatorics and Graph at the University of Jember hosted Dr. Kamal Dliou from Ibn Zohr University, Morocco, as a visiting researcher. His visit marked an important academic exchange, where he contributed significantly to the ongoing research efforts at the institution. As part of his engagement, he participated in a Focus Group Discussion (FGD) focused on the topic, "L(2,1)-Labeling of the Iterated Mycielski Graphs of Graphs and Some Problems Related to Matching Problems." The discussion revolved around complex combinatorial problems and the potential solutions that could be applied to various graph structures. This session helped uncover new perspectives on unresolved issues in graph theory and provided valuable input for future research directions.
The program also included a visit to Sekolah Kopi Raisa, located in Sumberwringin, Bondowoso, which is known for its community-based coffee education. The visit fostered collaboration between the academic community and local experts in coffee farming, combining theoretical knowledge with real-world practices. During the visit, Dr. Ika Hesti Agustin, M.Si., delivered a talk on "Dominating Set and Its Application," where she connected abstract mathematical concepts to practical applications in various fields. This session also served as an opportunity for local coffee experts and academics to exchange ideas, enriching both the scientific and practical knowledge of participants. The event underscored the importance of integrating local knowledge with academic research for community empowerment.
The outbound meeting concluded with a dynamic sharing session featuring Prof. Drs. Dafik, M.Sc., Ph.D., who presented an engaging lecture titled "Node Embeddings, A New Approach on Graph Neural Networks." His presentation introduced cutting-edge approaches in machine learning and graph theory, showing how neural networks can be applied to solve complex problems in graph analysis. Following this, Robiatul Adawiyah, S.Pd., M.Pd., delivered a comprehensive presentation on "Metric Coloring on Graph Theory," which addressed another significant area of research in combinatorics. The day ended with a productive FGD session aimed at establishing long-term research collaborations between the University of Jember and Ibn Zohr University. The discussion laid the groundwork for future joint research projects, particularly in the areas of combinatorics and graph theory, strengthening ties between the two institutions.
