INPEX scholarship foundation arranged this shaonkai meeting to congratulate me on my graduation and also to honor my professor.

I got this qualification in 2006, and at the same year my wife got 3rd level. Later in 2007, my wife got her 2nd level certificate.

Classical guitar performance

Performance again, with two songs composed by Jubing Kristianto: Song for Renny and Rickshaw.

Excellence Award - Intro to Intermediate Japanese (2005)

Classical guitar performance
INPEX Year-End Meeting 2004

I made my performance in this event with two songs: Greensleeves and Marriage D'amour.

I love classical guitar and wish I had a chance to take a formal class. A friend, Eka Juan, taught me how to play those two compositions when we were both in Junior High School. Then I moved to another island where classical guitar is not popular at all. I continued to practice with the help of a dusty old-book found in local library, published in 1970s.

Landed on Japan


Young Lecturer, Department of Chemistry, Brawijaya University

I joined in the Chemistry Department of Brawijaya University as a lecturer when I was 21st old. The picture shows young lecturers who were appointed at the same year

INPEX Scholarship and Australian Development Scholarship

Both foundations notified me as their scholarship student, but it was almost impossible to study at two continents at the same period, so I decided to take the scholarship from INPEX foundation (belong to a Japanese oil company of the same name). INPEX foundation announced their selection result earlier than Australian Development Scholarship.

Writing Visual Basic Game Programming Book

First, I built a web site to share my work in game programming, and then I decided to write a book to share my knowledge in game programming. The book was written in Indonesian Language, and it was published by ANDI Publisher Yogyakarta. When I'm writing this paragraph, the book has been reprinted for the third times.

Bachelor Course Graduation

New record for the highest GPA

The Youngest Cum Laude

I finished my bachelor course in Brawijaya University in 3.5 years with 3.75 GPA. It was the new record in Mathematic and Science faculty at that time.

My parents couldn't come to the ceremony, so my GF and one of my senior came to represent them.

Scholarship from Djarum Company
Scholarship from Brawijaya University

Djarum is a cigarette company, but the scholarship is open for non-smokers and in fact I'm againts smoking. I got Djarum scholarship at the last year of my bachelor course.

Part-time job in cram school

At the end of the first year in university, my mother told me to quit my study because she cannot support me anymore. I refused to give up, and looked for a chance to get some pennies. Unlike in developed country, looking for an acceptable part-time job in Indonesia is hard. I ended up in a new established cram school, which later developed into Sigma Education Center. It's not really a part time job to say because in many occassion I have to teach from 2 to 10 PM. Most of my students are from St. Yusuf senior high school, and the rest are from St. Albertus senior high school.

Teaching in Kedampul village

Kedampul is a small-traditional village and categorized as a poor-village by the government. I taught students of local elementary school in there for 1 month (last January 2002). I spent most of my time to motivate them to pursue higher education. Unforunately, their parents hardly expressed any interest to support them.

Entrepeneurship seminar

Two days seminar. An interesting quote from the main speaker, "Indonesian people hardly want to become an entrepreneur, but gladly want to be a part of military. They are afraid to lose their money, but they are not afraid to lose their life."

Highest NEM

It was the highest in my school, in region II, and I was told that the score for the chemistry field is the highest in province level. From left-to-right: Me, Erminawati (Teacher), Dewi Rahmadani (Silver medal), and Harris Domili (Bronze medal).

NEM = Pure National Examination Score

Book Review Competition (1st rank)

The book subject was related to Tempe from Kecipir (Psophocarpus tetragonolobus).

The competition was held during the 52th year Indonesia Indepency celebration.

Stamp Design Competition (2nd rank)

In both competitions, the first-place was all taken by Kristian Restu. He is a good illustrator and we worked together in the journalistic club.

Scholarship from Ministry of Education

A very small scholarship for one year. The payment date is uncertain, so we often visited the nearest postal office to ask whether the scholarship has been paid or not.

Creativity Competition (Siswa Teladan) - 1st rank: Capital city round

Creativity Competition (Siswa Teladan) - 3rd rank: Province round

"Siswa Teladan" means a student who serve as a good model for other students. The competition start locally in major cities, then provinces, and finally at national level. Personally, being a delinquent student at that time, I believe that I do not deserve for the title, and the referees may have committed a sinful act for this. All of my trophies were kept in the school.

Chief Editor of Senior High School Press

Being a freshman, I was irritated to see that the wall-magazine in my high-school was dreadful despite that the journalistic-division consists of fifteen members. I was sent to a three-days journalistic workshop at Mulawarman University, and then appointed as the chief editor of journalistic club while the original team was disbanded. I decided to work with a four-membered team. The publication was then running regularly and we received a good appreciation from the students and the teachers.

Chemistry study group - Senior High School

My interest in chemistry was started in this small study group.
