Guest Lecture by Practitioners of Mathematics Department: Artificial Neural Networks by Avan, Risk Modeler Bank Mandiri

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 →

Data Science Research Group FMIPA UNEJ holds Book Review of Variable Selection

News, Student, , , , ,

The Data Science Research Group (KeRis DSc) held a book discussion on Variable Selection in Predictive Modeling for Statistics and Machine Learning on December 2nd. The event featured Dr. Bagus Sartono, S.Si., M.Si., Chairman of FORSTAT and Head of the Statistics Department at IPB University, and Prof. Dr. Vita Ratnasari, S.Si., M.Si., a Professor of Statistics at the Sepuluh Nopember Institute of Technology. The event was held at the UNEJ Entrepreneurship Building and was opened by the Dean of the Faculty of Mathematics and Natural Sciences (FMIPA) at UNEJ and President of IndoMS, Prof. Drs. Dafik, M.Sc., Ph.D. In his speech, the Dean praised KeRis DSc for initiating the book discussion to promote a culture of mathematical literacy. “This is a very interesting book, discussing machine learning which will eventually lead to ‘black box’ models,” he said.

The Dean explained that the black box approach could speed up coding when developing application programs. “I hope this book discussion will be useful for the advancement of mathematics, especially statistics, and inspire other research groups in FMIPA,” he added. The book *Variable Selection* is written by Bagus Sartono, Alfian Futuhul Hadi, Evi Ramadhani, and Akbar Rizki. Prior to the discussion, Dr. Mohamat Fatekurohman, S.Si., M.Si., Chair of KeRis DSc, expressed his appreciation to the team for organizing the event in such a short time. He mentioned that after a period of inactivity, DSc is starting up book discussions again, with plans for guest lectures and seminar series in the future. Continue reading →

Umi Lailatul Jamilah, Physics Lecturer FMIPA Develops Real-time Guidance Commission Academic Services

News, Student, , ,

As part of the 2024 CPNS Basic Training, Umi Lailatul Jamilah, M.Si., a Physics lecturer at FMIPA University of Jember, developed a digital-based academic service system called Kombi in the Department of Physics. “This development is a way to apply the Smart ASN values in institutions, by creating an interactive website for the final project registration process,” said Umi. Previously done manually, now students can register for their final project, seminars, and exams directly through the Department of Physics website. This will make the bureaucracy more effective, efficient, and faster.

According to Dr. Ratna Dewi Syarifah S.Pd., M.Si., Head of Kombi at the Department of Physics, the system is also designed to be more flexible and transparent. “Real-time information will automatically sync with students’ final project data,” she explained. This data includes student bios, research titles, names of advisors and examiners, and seminar/exam schedules. Dr. Ratna, who is also a mentor for the program, added that students can now access up-to-date information about the progress of their final projects.

The system has also been enhanced with an automatic diagram that shows the distribution of final project advisors. Umi explained that this will allow the department leadership to regularly monitor students’ final projects. Dr. Agus Supriyanto, S.Si., M.T., Head of the Department of Physics, emphasized that transparent and accessible information is crucial for any service system, including Kombi. “Information that is easy to access and provides valuable knowledge is the essence of an effective information system,” he said.

Endhah Purwandari S.Si., M.Si., a former head of Kombi at the Department of Physics, noted that digital services like this are not only needed by students but also by department leaders. “The department needs this for improving the quality of academic services,” she said. This development will also be an important part of the Physics Department’s accreditation evaluation. The hope is that this program will be beneficial, sustainable, and have a positive impact on many parties.

Retired Ir. Misto, M.Si: Physics Department FMIPA UNEJ holds Public Lecture and Farewell

News, Student, Tokoh, , , ,

The Physics Department of the Faculty of Mathematics and Natural Sciences (FMIPA) at the University of Jember held a public lecture and farewell event for Ir. Misto, M.Si., who is retiring on November 30th. In his speech, the Head of the Physics Department, Dr. Agus Suprianto, S.Si., M.T., expressed gratitude and appreciation for Mr. Misto’s service. “On behalf of the Physics Department, I would like to thank and honor Mr. Misto for his dedicated contribution in sharing valuable knowledge,” he said. As a colleague, Dr. Agus shared that Mr. Misto had made many contributions to research and community service. “He is a senior physics lecturer who always provided advice to us younger faculty members and was a great teacher who was always willing to engage in discussions with students,” he added.

The event was attended by all the lecturers and administrative staff from the Physics Department. The event began with a public lecture, during which Mr. Misto gave a talk to physics students from various year groups. He shared the story of his journey from becoming a lecturer to his years of service at FMIPA, leading up to his retirement. “At the end of my service, I want to share my knowledge, especially in physics, for the advancement of medicine, which has been part of my journey as a lecturer,” he said. Mr. Misto has worked on several collaborations to show how physics can greatly benefit human health, particularly through medicine.

He explained that not everything dangerous is harmful if used in the right way. “Gamma rays from radioactive materials, if used correctly, can be used to treat cancer,” he explained. The radiation can damage the DNA of cancer cells, which helps slow the growth and spread of cancer. “Although there are side effects, like loss of appetite, this can be managed by eating fruit,” he added. The event ended with the students presenting Mr. Misto with a gift.

The farewell event continued with a video presentation from colleagues and staff, who shared messages and memories of Mr. Misto. “He is a role model who is always enjoyable to discuss with, whether it’s about lectures, research, community service, or even life in general,” said a fellow lecturer. Many gifts were presented to Mr. Misto, from colleagues, alumni, and the department. The event concluded with a group photo, karaoke, and a lunch together.

Congratulations on your retirement, Mr. Misto, and thank you for your dedication and service to Physics, FMIPA, and the University of Jember.
