DazaifuToday’s Dazaifu is regarded as the well known tourist destination in Kyushu, Japan. Dazaifu or “Government-General Headquarters” was established approximately 1300 years ago and ruled all Kyushu area for period of some 500 years.

Visiting this historical site on Friday, Nov 23, has reminded me to an old city of Kotagede in Yogyakarta, Indonesia. Even though these two sites are different to some extent, however they are similar in terms of their important role in the past as the center of governmental headquarters. Kotagede was established some hundred years ago and was the center of the early Mataram Kingdom which was later divided into Kasultanan Yogyakarta (Yogyakarta Kingdom) and Kasunanan Solo.

Back to Dazaifu. There are numbers of historical sites which reflects to the ancient history of Dazaifu, including ruins of the Dazaifu itself, ruins of Mizuki, ruins of Onojo, Kanzeonji Temple, ruins of Chikuzen Kokubunji Temple and Dazaifu Tenmangu Shrine. These sites are distributed around the Dazaifu region.

Dazaifu Tenmangu Shrine is dedicated to the Michizane Sugawara, “the God of Literature”. In 901, Sugawara was abruptly exiled from Kyoto as the Dazaifu official by the Emperor’s court, and he died two years later. The shrine was built over his grave and was constructed in 1591 A.D.

Kanzeonji Temple, mentioned in The Tale of Genji, was opened in about the year 746 at the command of the Emperor Tenji to honor the deceased Emperor Saimei. The temple flourished as one of he key religious centers for Kyushu, as reveled by the many Budhist statues and its temple bell, which has been designated a national treasure and is the oldest in Japan.

Ruins of Dazaifu-Seicho (Dazaifu Government Office). Dazaifu-Seicho, also known as “Tofuro”, was once the place of the government office for entire Kyushu region. This place played an important role in defense of the western Japan and as a diplomatic gate from the second half 7th century through Nara and Heian period (710-1185 A.D).

Kyushu National Museum, the largest national museum in Japan is built in this site. It exhibits Japan’s cultural formation from Paleolithic period to the end of modern age (1850’s) with their basic philosophy: “Museum with formation of the Japanese culture from the Asian historical viewpoint”. (Some of the information is cited form the Daizafu: Home of the Chikushi Manyo Poetry leaflet, with modification).

Lost in the City


A map does not mean “only a map”, only a picture that visualizes location of objects on the earth. For me, a map means everything; everything related to geospatial information and its related attribute data. A map is a guidance that helps us to understand a place and to be well oriented geospatially.

Every time I go to new places, I always try to find a map of the place beforehand, by buying a printed map if it is available in shops, or by searching digital maps on the internet as well as visit google maps website. Few years ago, before visiting Melbourne, I bought a map of Melbourne city and its surrounding areas in Jakarta. As well as when I visited Kuala Lumpur, I tried to look for a map of Kuala Lumpur city soon after I arrived in the city. From the maps, I could get many information about the city and explore the city well.

However, having a map in hand does not always mean that you will be well oriented in a new city; at least this is true for me. Until more than six weeks since my arrival in Fukuoka City, Japan, with a map of Fukuoka City in hand, yet I could not point important places of the city on the map, even my own house (maybe it sounds ridiculous because I am a Geodetic Engineering graduates). Why? Because the language that is used for composing the maps is Japanese language with Kanji letters, the thing that I do not understand.

From this instance, I then realized that in toponimy (i.e. the map lettering and naming systems) one of the key factors in order maps are readable and understandable is language. The Fukuoka City map maybe toponimically is good for Japanese people or non Japanese people who can read Kanji letters and understand Japanese language. On the other hand, it can be said that the map is toponimically not appropriate for non Japanese people like me. For a big city like Fukuoka, with so many foreigners reside in the city, it sounds ridiculous to notice that there are no (or very difficult to find) non Japanese language based city maps. Since almost all public facilities, public transport, street names, and only very few number of Fukuoka City people who can speak English, it is most likely for new foreigners who are not be able to read Kanji Letters and Japanese Language to experience lost in the Fukuoka City of JAPAN.

University Summit in Kyushu 2007


The second university summit was hosted by Kyushu University in Fukuoka on 26-28 October 2007. Kyushu University convened the first “University Summit in Kyushu” in May 2000 for the purpose of discussing current challenges facing university management, as well as research and educational activities in a global context with senior executives from leading higher education institutions. Through the two forums, Kyushu University is trying to deepening its contribution to international higher education and international society.

The second University Summit is part of an extensive program of events culminating in Kyushu Universit’s centennial anniversary in 2011. The summit highlighted the theme of “Integrating Global Universities and Local Communities in the 21st Century”. Six universities represented by their institution leaders participated and presented their papers in the events. Those six universities are: Gadjah Mada University (Indonesia), University of Tehran (Iran), Chulalongkorn University (Thailand), University of Sao Paolo (Brazil), Shanghai Jhiao Tong University (China), and Kyushu University (Japan).

In this event, Gadjah Mada University was represented by University Chancellor Prof. Dr. Sudjarwadi, accompanied by Dr. Joko Luknanto. Some of the Gadjah Mada University staffs who are currently studying in Kyushu University were also invited to attend the event on the second day. In that event, Prof. Dr. Sudjarwadi presented a paper entitled “The university as a resource for prosperous local communities: a case study of Gadjah Mada University”. After the summit, Prof. Sudjarwadi invited us to discuss about the Gadjah Mada University current condition and future plan. The discussion was started at 18pm and finished at 22pm.

The Journey to the Other Planet

Purnama“You have to go to the other planet!” Those are the words spoken by my colleague to me when he knew that I was accepted to study my doctoral degree in Malaysia few months ago; as a courteous response of his disagreement if I study in that country. And now, his words come true! Yes, I’m now living in the other planet named JAPAN! Maybe the words he said few months ago was a “doa” (words of worship) for me. Only Alloh knows.

Kyushu University, one of the best universities in Japan, and even in the world, is the place for pursuing my doctoral degree in engineering. I had never realized that I would study in the “country of the other planet”. This opportunity just came to me easily and smoothly, not as difficult as most of my friends experienced to get a scholarship to study there. This journey was started few months ago when a friend of mine who is my colleague from Geology Department UGM, who at that time was a research associate in the Department of Earth Resources and Engineering, Kyushu University, sent email to two of my colleagues at my Department, informing that there were some scholarship for international students to study for PhD in Faculty of Engineering. The email was actually also intended for me, but because my colleague from Dept Geology UGM did not know my email address, he asked my two colleagues for help to forward the email to me. Based on this information, I then tried to search the potential supervisor in the Faculty of Engineering, University, who has the same interest in research area. From the University website, I found that Environmental Geo-Technology Lab, Department of Civil and Structural Engineering, is the most suitable lab for me, with one of the research areas is Geographic Information Science. I then contacted Prof Tetsuro Esaki, the head of the laboratory, through email attached with my CV and proposed research outline, confirming my intention to study. Few days later, he responded my email, telling me that I was put as the highly ranked candidate against the other candidates from other countries such as China, Bangladesh, and Nepal as well as Indonesia.

Few months later, I met my Dept Geology colleague (he at that time was a HiLink Research Project official who supervises my department project funded by JICA) in my office. He congratulated me for my successful achievement in getting the Monbusho scholarship. I always remember his words. He says, getting a Japanese scholarship are very difficult for most people. But either way, it is seems so easy for some people.

Indeed, I feel my way to go to “the other planet” was very easy. Alhamdulillah, all the praise only goes to Alloh, my GOD, my KING, my GUARDIAN, my GUIDANCE. And thanks to my beloved wife who finally agree with my decision to study in “the other planet”.

Special day of ToDay

Every people has a special day or even more than one. For me, today is one of my special days. WHY?……..

Today, September 25th 2007, is the day when this “my” personal website is launched. This is one of my momentous day because one of my obsession has already been realized.

Today, September 25th 2007, is my special day because today is “11” days away from the date that I have to go to Kyushu University, Japan for doing my PhD. Number “1” that composes “11” is magical number for my family because my son was born on day 11, month 1 and year 1 (2001).

Today, September 25th 2007, is my special day because 35 years ago, at night on that date, when the moon reveals its full face, a little gorgeous boy was born in an old town of KOTAGEDE.

And today, September 25th 2007, is my special day because today, in the holy month of Ramadhan, I can feel plentiful blessings from the Greatest Allah for me, health, happiness, lovely family and lives.
