“Active Learning Special Lecture” -welcome to the high-pressure world-

On February 27, 2021, we have done a one-day program to fully learn physics with professors and students at Shibaura Institute of Technology (SIT). This event is a collaboration between SIT and SMANISDA, SMAN 1 Sidoarjo. Initially, this kind of program is organized by Prof. Ayako Yamamoto, on the basis of her research’s outreach activity in 2019.

The event was successfully held on-site at the SIT Toyosu campus for the Japanese high-school students. And then, in 2020,due to Covid-19 situation, the event was held on-line. Reflecting the successful on-line program Prof. Yamamoto proposed this event to the foreign staff in SIT, especially in the Innovative Global Program (IGP) course where there are many foreign Professors such as from Indonesia, Taiwan, China, Vietnam, Malaysia, India, Europe, the US, and the UK, and expanded the target of students to be international high-school students. The 20 best-students in the 12th grade from SMAN 1 Sidoarjo have been selected to join this event.
Alongside the school head, the Physics, English, and the Counselling SMAN 1 Sidoarjo teachers were also fully supporting to organize this active learning program. All of them were joining online from Indonesia by using Zoom platform. The students were given three lectures about “pressure and three states of matter”, “various high-pressure ice”, and “natural and artificial diamonds” by Prof. Ayako Yamamoto.

After each lecture, there was a live experiment performed by Bachelor and Master course students in Yamamoto-lab (Ryota Furui and Takeru Sato, respectively) or an exercise using an experimental tool. The students were then divided into five groups (A – E) and moved to a breakout room to do a group discussion. Each group was mentored by a facilitator. Two of the facilitators were Prof. Yasuyuki Ishii (Japan) and Prof. Izabela Rzeznicka (Poland) whose research are about experimental condensed matter physics and surface chemistry, respectively. Another facilitator was Dr. Dita Puspita Sari (Indonesia) who is an Assistant Professor in the IGP and Prof. Ishii-laboratory. Dr. Dita is the alumnae of the SMAN 1 Sidoarjo and did promoted SMAN 1 Sidoarjo to be the target for this event because SMAN 1 Sidoarjo has the international standard high-school program. The other facilitators from Indonesia were Miss Anna Zakiyatul Laila who is a PhD student of Prof. Ayako Yamamoto, and Mr. Ihsan Budi Rahman who is a PhD student of Prof. Izabella Rzeznicka. The active learning program started from 11.00 am Japanese Standard Time (JST) or 9.00 am Indonesian Western Time (WIB). After the opening and short greeting from Prof. Yamamoto and the school head of SMAN 1 Sidoarjo, Mister Eko Redjo Sunariyanto, the first lecture was given.

group discussion

At 11.45 am JST the live experiment to obtain the liquid of CO2 was performed by Yamamotolab students. The experiment was nicely performed so that the students can observe the triple point of the CO2 at which the solid, liquid, and gas exist at high-pressure of 0.5 MPa. The experiment was followed by a group discussion and then a presentation from a representative student from each group.

lecture and experiment

At 12.30 pm JST the second experiment “crystallization of water at room temperature” was performed. Prof. Yamamoto showed the experimental setup using the pressurizer tools (up to 1 GPa) connected to a camera. Students were able to see the process of the water crystal growth under pressure. The lively experiment was possibly done with a live-time discussion through the Zoom chat session. After that, the second group discussion was followed as well as a presentation from the representative student.

At 12.50 pm JST the second lecture was given to explain what was going on in experiment 2,and all the participants were seriously paying attention and thinking about how the water can be a single crystal of ice at room temperature. That was because the high-pressure up to 1 GPa was applied to the one piece of small ice that obtained with pressure fluctuation.

summary

At 12.58 pm JST Prof. Yamamoto gave the summary of the morning lecture and there was a lab tour by Yamamoto-lab members. Students were introduced to several advanced experimental tools in the SIT Techno plaza (X-Ray power diffractometer) and Yamamoto-lab (High-pressure synthesis machine, Physical Properties measurement system with a cryostat which can cool the sample down to 50 K, and the SQUID Magnetic Properties measurement system with a cryostat which can cool the sample down to 2 K. After that, all the participants took a break for lunch and pray.

At 14.00 pm JST Prof. Yamamoto gave lecture 3 “Natural and artificial diamonds” and followed by the exercise to see natural and artificial diamonds by the optical microscope. After that, the group discussion and the student presentation were also followed. The afternoon session was summarized at around 15.15 pm JST.

At 15.20 pm there was a sharing knowledge session by an Indonesian IGP student, Christoper Jonathan, and the introduction of research studies by the Indonesian PhD students, Miss Anna Laila and Mr. Ihsan Rahman. The students were asking several questions through the chat room.

Finally, at 15.50 there was a closing ceremony with the certificate awarding for SMAN 1
Sidoarjo. All the students were also given a certificate of attendance and one student was
awarded as the best student presenter. The photo group session was perfectly close to the event.
