The Faculty of Mathematics and Natural Sciences (FMIPA) of Yogyakarta State University (UNY) once again held a historic moment in the academic world. On Monday, April 6, 2026, an Open Session for Doctoral Promotion was held for Eka Senjayawati. This prestigious event was held solemnly and marked the culmination of the student's academic journey in completing the third strata (S3) program in the Mathematics Education Study Program. The implementation of this open session was attended not only by the academic community in person but also broadcast live to a wide audience. The public can watch the academic procession through the official YouTube channel of the Faculty of Mathematics and Natural Sciences UNY, namely "fmipaunyofficial". This step provides transparency and an opportunity for colleagues and extended family to witness this historic moment from anywhere, without being hindered by distance. Promovenda Eka Senjayawati herself is not a new figure in the world of mathematics education in Indonesia. He is known as one of the highly dedicated lecturers and academics at the Siliwangi Institute of Teacher Training and Education (IKIP). His strong desire to deepen his knowledge and make a broader contribution to education in the country has led him to pursue a doctoral degree at Yogyakarta State University.

Very thick, formal academic nuances marked the atmosphere of the open session. This session was led directly by the session chairman and attended by a team of promoters, co-promoters, and examiners, all experts and professors of mathematics education. The academics who attended also lent legitimacy to FMIPA UNY's consistently high standards of scientific quality. On this valuable occasion, Eka Senjayawati presented the summary of her dissertation with confidence. The presentation summarized the results of the in-depth research he conducted during his doctoral studies. Concisely and comprehensively, Promovenda explains the problem background, the research methodology, and the latest findings that constitute the research's novelty. The study proposed by Promovenda is highly relevant to the various challenges of mathematics education in the modern era, which are closely related to the development of mathematical reasoning, didactic design, and higher-order thinking skills. Through this scientific research, Eka Senjayawati seeks to provide practical and theoretical solutions to improve the quality of mathematics learning at various levels, an issue that has long been the focus of her dedication.

After the presentation session, the event stage continues with a question-and-answer session or an oral exam, which is the most crucial part of a doctoral promotion session. One by one, the examiners raised questions, rebuttals, and critical reviews of the dissertation manuscripts. The questions are specifically designed to test the depth of understanding, the sharpness of the analysis, and the academic ability of the promovenda to defend their arguments. Facing various critical questions from the examiners, Eka Senjayawati showed her extraordinary intellectual maturity. He can respond to every question with calmness and straightforwardness, grounded in empirical evidence and a solid theoretical foundation. This very comprehensive mastery of the material makes the session atmosphere more lively, with a healthy, constructive scientific dialectic. After a long and in-depth question and answer session, the chairman of the session postponed the trial for a moment. The board of examiners then held a closed-door consortium meeting to provide a final assessment and determine the promovenda's graduation. This moment of pause is always the most thrilling, not only for Eka Senjayawati personally but also for the audience who always pray for it. The tension finally faded when the session chairman again tapped the hammer to open the trial and read the examiners' meeting results. With an atmosphere full of emotion and pride, it was announced that Eka Senjayawati had passed and successfully defended her dissertation. From the moment of the hammer knock, he is legally entitled to hold a Doctorate (Dr.) in the field of Mathematics Education.

The event then continued with the delivery of messages, impressions, and mandates from representatives of the promoter team. In his remarks, the promoter representative expressed his highest appreciation for Dr. Eka Senjayawati's hard work, fortitude, and extraordinary dedication during his hard S3 education. He advised that this doctoral degree is not the end of a search for knowledge, but the initial gate for much greater service to the community. The brilliant achievement of Dr. Eka Senjayawati is not only a source of pride for herself and her family, but also for the alma mater of Yogyakarta State University and its home institution, IKIP Siliwangi. Its success in this highest academic realm is expected to be a real inspiration for educators and students across the country to continue working for the advancement of Indonesian education.
