Short Stay in Chiba University

From 28 November – 12 December 2011 I had an opportunity to  visit Japan, at Chiba University in a program called a Short Stay Program. This program is a pre double degree program prepared by the Chiba University to introduce the various research conducted in Chiba University. In these programs we were intended to explore and observe the ongoing research at the research centers in Chiba University. In this program, other participants from reputable university in Indonesia are also invited. Together there are 17 people of us in this program including our Indonesian Supervisor, Dr. Hendarto. The students are from University of Indonesia, Institute of Technology Bandung, Padjajaran University, Gajah Mada University, Hasanuddin University and Udayana University.

By the morning of the 28th November, the 13 of us, supervised by Dr. Hendarto had landed at Narita International Airport, while the other 4 students had already arrived the earlier night.  We continued from the airport to the dormitory where Prof. Josaphat had awaited and welcome us.  In the dormitory we were introduced by Prof. Josaphat and his assistants regarding our short stay program. We immediately divided into small groups according to our specialized program. For my self and my friend from University of Indonesia, Rendy Tama, we were assign under the supervision of Prof. Josaphat himself at the CeReS Laboratory. On that day, we were allowed to rest and conform ourselves with help of his assistant Mr. Yudo Prasetyo and Mr. Ilham Alimuddin.

The next day and the following day we were mostly assign in our designated research laboratory. Other activities at the research center include a training/workshop and seminars held at the CeRES research center. Such training/workshop was given at the 5-6 December 2011 called “Synthetic Aperture Radar (SAR) Basic Processings ” and seminars was held at each of research laboratory. Another kind of activity we attend to is the introduction of several Japanese cultures such as Tea Ceremony and Origami Class. Here is the schedule and main activities on our short stay programs

Welcoming and farewell party by  Chiba Indonesian Student (PPI Chiba).

  11. 11 December 2011 :

Back to Indonesia.

Supervised by Prof. Josaphat, I learned about his laboratory which has a diverse approach regarding Synthetic Aperture Radar. This approach includes both theoretic and practical measures. This measure surely gives advantages to the laboratory, because not only the studies are conducted on papers but also the development of the new sensors and unmanned aerial aircraft gives it a complete perspective on the SAR remote sensing. In fact, Prof. Josaphat said that his laboratory will be given a chance to develop its own satellites in the coming year. This incredible news will certainly gives CeRES valuable prestige in the SAR research community.

At the CeRES Laboratory I also learned about SAR from Prof. Josaphat students, they give me a  guidance through various literature and study cases. In this laboratory I realized that this laboratory consist of people with different nationality, although most of are Indonesian, this indicates that this laboratory had always been an interest from various university around the world. One of the main usage of SAR in this laboratory is to measure land subsidence.  The basic idea for the generation of land subsidence products is the conversion of differential interferometric phase information, derived from three or more SAR acquisitions at different dates from slightly different orbital positions, into displacements (DInSAR technique).

From those activities we had so much experiences and understanding about research at the Chiba University especially within CeRES Laboratoy. This program has gives us a broad view of studying in Chiba look like. Learning in Chiba definitely has many advantages, a lot of international students in the lab already shown that interest. I am lucky to be involved in this short stay program, because I have learned more about remote sensing and even in advanced ways. During the short stay I realize that with SAR one can make high resolution images of the sea surface. This is important for Indonesia which is a maritime country and especially when you learn about oceanography. Microwaves penetrate the clouds and thus radars are ideal remote sensing instruments. SAR extracts all information about oceanic and atmospheric phenomena from sea surface roughness variations. Some ocean phenomena detectable by SAR is Internal waves, oceanic fronts, oil pollution, oceanic eddies, ocean surface waves.

The most unfortunate thing for me is that in the earlier study I have taken an interest to a different field study of remote sensing. Satellite Altimetry. It has been an ongoing research for me which start from my undergraduate final project until now in my graduate study thesis. In the future, with this interest of SAR remote sensing and my knowledge about altimetry it is very tempting to combine these two (altimetry and SAR) methods to observe the ocean. It could be the way to know more about the Indonesian seas. If there is a chance in the upcoming years, I would lovely try to gives attention to study about the usage of SAR in the ocean.
