The session began with an opening by the head examiner, Mr. Zakki, followed by a 20-minute presentation by the student and then a discussion. The presented material was very engaging, highlighting both its strengths and weaknesses. Based on the material presented, the student developed a nanomaterial-based substance, copper carbon dots (Cu-CDs), applied for histamine detection. This development is highly beneficial for food quality control processes, especially in seafood like fish. During the discussion, the examiners posed questions and sought clarification on Desita’s presentation. They also provided numerous suggestions and recommendations for further research improvement and development.

The examiners conveyed several important messages. They emphasized that in research, it is normal to encounter unexpected outcomes, but one should remain confident in their results. This confidence helps in learning from mistakes and understanding errors. Furthermore, they stressed that even though research often focuses on laboratory work, theoretical knowledge provided by professors should not be forgotten. Hence, the learning process, whether from laboratory experience or during lectures, should be well-utilized to gain valuable insights.
