Physics Education Department holds Studium Generale with Foreign Lecturer from the UNSW
FITK, UIN News Online – Department of Physics Education held a Studium Generale on Friday (25/10/2019) from 13.30 to 15.30 at Prof. Dr. Mahmud Yunus theater 3rd floor, Faculty of Teaching and Teacher Training, UIN Syarif Hidayatullah Jakarta.
Co-dean of Academic Affairs Mr. Zuhdi inaugurated the program. In his speech, Mr. Zuhdi gratitude the speaker for his presence in a short notice and wish that the audience who is 3rd, 5th, and 7th-semester Physics Education undergraduate students could have an insight of the research on physics and physics education. Mr. Zuhdi also hopes that the program can give ideas and inspire the students to write the paper for last year's requirement to graduate.
"UNSW is my alma mater. I have a picture of me standing in front of the library there. I encourage you to go and study there and take a picture in front of the library by yourselves," He said to motivate the students.
The speaker for this studium generale was Associate Professor Dan McCamey from UNSW's School of Physics Australia, with the theme was Exciton Science towards Sustainable Energy Future.
"I was interested in Physics because of my year 11 and 12 fantastic Physics teacher. He inspires me to love and curious about physics," Mr. McCamey stated at the beginning of his presentation.
Great people come together to join the Australian Research Council Centre of Excellence in Exciton Science from around the globe. They are focusing the research, in theory, spectroscopy, materials, and devices.
In theory, the researcher modeled a material with all desired properties with the computer application. And then, spectroscopy and materials do the work together, making a loop work. Spectroscopy measures and characterizes the materials. It will give information about the materials' properties, then these properties were matched with the model, and there will be an improvement to those materials.
One of the outcomes of this research is that this material is used for making a money bill. For security reasons, it is hard to fake.
Besides that, the research leads to the making of materials that can harvest light energy into electrical energy more efficiently. Since 11 percent of total global energy use is for street light and displays. The improvement in efficiency will save a lot of energy.
Many branches of physics also support this material research; one of them is high energy physics. The researcher employs the exciton concept to describe their findings.
The exciton is a pair of electron and hole in the tetracene and pentacene crystal. The crystal can transform photon into an exciton. With the help of potential differences, two excitons can be combined and converted back into a higher energy photon. By this exciton in the material, we can increase solar cell efficiency from 25% to 33% up until 44%.
In the end, Mr. McCamey emphasizes that this research is not only from personal knowledge, but it's from the collaborative action of several scientists instead.
Mr. McCamey said that UNSW open to international partnerships. UNSW is open for registration for the students with exceptional achievements or the students who have the idea to change the world.
The students were engaged, and they asked several questions to the speaker at the end of the presentation. The faculties of the Department of Physics Education were present there; Mr. Iwan Permana Suwarna as head of Department, Mr. Dwi Nanto, as a moderator, Mr. Dzikri as the chairman of the program, and some other lecturers.
