I participate in AOTULE Sumer Program 2018 at Institut Teknologi Bandung (ITB) in Indonesia
from August 1 to August 18. The theme of this program is Green Energy, Environment & Sustainable
Infrastructure. This theme is not my specialty. But, I can understand the theme due to detailed
explanation. And also, I understand the necessity of sustainable society.

ITB is the best university in science and technology in Indonesia. Since it was established in 1920,
many important people for Indonesia such as President Soekarno were graduating from ITB. In thecampus, there are many traditional and unique buildings.

2. Class of this projectClass of this project can be divided into three parts; Lecture, Indonesian Language and Group work.

a. Lecture
There were 13 lectures about Green Energy, Environment & Sustainable Infrastructure in this project;
Introduction to Geothermal Energy, Topic on Wastewater Treatment for Electricity, Topic on Natural
Coastal Protection and so on. Lectures are basically divided into two parts. In the first part, participants
take a lecture by professor or doctor student about 90 minutes. After coffee break, in the two part wevisit laboratories and watch equipment. The lectures include basic content. So, I was able to understandfrom the beginning. I could have an interest to sustainable society. I would like to make the most ofwhat I have learned.

b. Indonesian Language
In this program, we took lecture three times about Indonesian Language. In the class, we studied
basics of Indonesian language such as number and self-introduction. Not only the teacher but also ITB
student teach us the language. It is said that Indonesian language is easy to acquire. I was not familiar
with the language. But, I could acquire little and I could buy of my dinner by Indonesian language.

c. Group discussion
In the final day, I gave a presentation which I discuss with my group member. The topic is to makesustainable town. The theme decided only the framework, so there were many ideas depending ongroups. In my group, there are three theme; green, river and farm. In our village, do micro hydropower with river and make many crops to export. Name of our village is “Mikachu”. Combined withfamous character, the reputation from other students was good.

3. Activity in free day
In free day, one ITB student hold a home party. In the party, he and his friends made Indonesian
traditional foods. They were delicious for me. In the we talked about traditional foods in our homecountry. I explained “Ohagi”. They had not eaten ohagi. If they come to Japan, I promise to treat
Japanese traditional foods such as ohagi. In another topic, we talk with Japanese culture. ITB student
shows their interest to Japan. I could not reply some questions about Japan. I learned it is important tounderstand my own country to make friend with foreign people.

4. Impression
What I felt strongly through this program is the need of raising my English skill. I think English
education of Indonesia is developing compared with Japan. This is because not only ITB students but
also some go-jek drivers (go-jek is a kind of taxi in Indonesia) can speak English well. I often failed tocommunicate with those people due to my poor English skill. In the future, I will get an opportunity towork with foreign people. In the opportunity, to work well I must raise my English skill.
I also had many other experience such as religion, heavy stomach ache and so on. I will never forgeta lot of things I learned in this program. Taking advantage of this experience, I will study and researchharder than before.
