The 4th European Physics Olympiad “(EuPhO) held online from July 20-26, 2020 provided a proving stage for Indonesia with the gold and silver achievements represented by an Indonesian team of 5 students. The 5 students consisted of Peter Addison Sadhani (SMA Santo Aloysius 1 Bandung), Timotius Jason (Ignatius Global School Palembang), Rizky Ramadhana (Taruna Nusantara High School, Magelang), Nixon Widjaja (IPEKA Plus BSD Tangerang Senior High School) and Fadli Januar (Featured High School MH Thamrin, Jakarta). each student brilliantly won the Absolute Winner (the highest score among all participants) and The Best Experimental Results (the highest experimental value among all participants).
The Indonesian representative was fostered by the National Synergy Foundation for Educating Tunas Negeri (Simetri) which is also an institution that specifically fosters the Indonesian Physics Olympiad Team (TOFI).
Hendra Kwee, Ph.D., Chair of the Indonesian Physics Olympiad Team and founder of the Simetri Foundation, said that this year the host of EuPho is Romania. However, because of Covid-19, the activities were held online. “The five students from Indonesia have been selected through national and gradual selection,” he said
the winner of the Absolute Winner and Best Experiment is Peter Addison Sadhani. Peter managed to achieve a value of 40.0 from a maximum of 50 which is the highest value in the history of Indonesia during participating in this competition.
The four silver medalists were Timothy Jason, Rizky Ramadhana, Nixon Widjaja and Fadli Januar. For this year’s team leader besides Hendra Kwee, there is also Herry Kwee, Ph.D., Zainul Abidin, Ph.D. and Jong Anly Tan, Ph.D. It was said, this year’s TOFI was actually selected and fostered to participate in the 21st Asian Physics Olympiad (APhO), which was originally held on May 10-18, 2020 in Taipei, Taiwan. However, due to the Covid-19 pandemic, the implementation of APhO was postponed to 2021. The implementation of EuPhO, which was also originally planned at Satu Mare, Romania on 2–6 June 2020, was shifted backward and the implementation became online.
For questions made quite real because there is experimental uncertainty on the results provided by the program. One of the problems of experiments is about scattering Rutherford using electrons. During the test, students can adjust the position of the electron firing and the initial energy of the electron.
Electrons are scattered by another large stationary charge and the three coordinates of their position are unknown and these electrons will be detected on a screen that is at an unknown distance from the charge. However, students must design experiments to calculate the position of the charge, and the size of the charge.
