News, , , , ,

The “MIPA Bergerak Sehat” event continues with a chess tournament. Representatives from various departments and the FMIPA deanery competed in chess in front of the Biology Department building. The players were divided into two groups, and the tournament was played in two rounds. The Dean of FMIPA UNEJ, Prof. Drs. Dafik, M.Sc., Ph.D., joined in the fun by participating in the chess match. “As I mentioned during the opening, now it’s time to compete in the chess tournament,” he said. As a warm-up, the Dean played a practice match with Prof. Dr. Kahar Muzakhar, S.Si. Although they were in the same group, they didn’t face each other directly. “Let’s practice first. Even though we’re in the same group, we haven’t met yet. I’ll wait for you in the final, Prof. Kahar,” said Prof. Dafik.

At the start of the tournament, four chess pieces and a timer were provided for each group. The organizers set rules that all participants had to follow. “We’ve set the rules, and we’re playing in the spirit of good health and sportsmanship, following the ‘MIPA Bergerak Sehat’ motto,” said Budiyono, one of the organizers. In the final round, Sapik from the Dean’s office faced Muhayat Zamroni. After a fierce match, Muhayat Zamroni emerged as the winner. The Dean hopes this event will continue, as it helps sharpen the mind and serves as a refreshing break from work. Continue reading →

News, Student, , , ,

Avan, S.Si., M.Si., an alumnus of the Mathematics program and a Risk Modeler at Bank Mandiri, began his presentation by discussing the current state of the banking sector, especially in risk management. The talk was part of a guest lecture for the Artificial Neural Networks course with the theme “Credit Risk Modelling” held on December 10, 2024, at the Mathematics Department. With nearly a decade of experience as a risk modeler at Bank Mandiri, Avan shared best and worst practices for building models. Most of the attendees, who were students, paid close attention as they were familiar with the model-building framework, similar to their final thesis projects in the Mathematics Department.

“Next, we’ll discuss issues related to imbalanced datasets and overfitting,” Avan said. These two problems often challenge mathematics students when working on their theses. He explained these issues in a clear and detailed way. The lecture also covered artificial neural networks, which are a popular machine learning model used in risk modeling. The guest lecture was held in a hybrid format, with both students and lecturers from the Mathematics Department of FMIPA UNEJ attending. Continue reading →
