Mungkin teman-teman KPLI Yogya dan sekitarnya tertarik untuk kerja sama,
memperkenalkan Linux ke rekan-rekan staff BPPTK ?. Sebab sepertinya staff
BPPTK mengalami sedikit kesulitan memahami peralatan yang menggunakan
Linux tsb... Menurut komentar Sven.. staff BPPTK "lebih menyukai" NT
8-) padahal untuk pekerjaan/peralatan tsb, NT "tidak mampu" menanganinya.
Rupanya sudah ada aplikasi Linux yang "cukup canggih" di Yogyakarta, dan
kita baru tahu.

Dear Made,
I hope you remeber our short talk at Jakarta Airport on Aug. 11. We
were on the same plane to Frankfurt. I took a while before I found time for
this email, but it was always in my mind and now that I have surfed your web
site - I the more think that this could the beginning of something
interesting...
As I already told you I am actually a (computing) physicist - now attracted to
the beauty of volcanoes and therefore working in the field of volcanology
for Leipzig University and the Volcanological Survey of Indonesia.
I would really like the idea of creating a more than symbolic link between
LINUX and Merapi volcano. This email shall tell you only briefly about
who we are, what we are doing and what I think we could be doing.
If you are still interested - more information can be found on my web page.
1. BACKGROUND MERAPI
As you know Merapi volcano is one of the most dangerous volcanoes of the world,
not only because of its frequent but lately smaller eruptions and its
explosivity but also because Central Java is very densely populated and
millions of people are threatened. Therefore, already in the early 90ies UNESCO
has announced an International Decade for Natural Desaster Reduction (IDNDR) and
selected Merapi as one of 15 so-called "Decade" volcanoes to be intensively
investigated by many different geophysical techniques. UNESCO has called on the
international
scientific community to make proposals for the investigation of Merapi and so
it came that DFG (Deutsche Forschungsgemeinschaft) is financing our research
since about 1996. During the last years I have personally organised and
supervised altogether 4 expeditions to Merapi volcano. A list of our
publications can be found on my web page.
2. WHO ARE WE
The German-Indonesian MERAPI project (the letters also stand for
Mechanism Evaluation - Risk Assessment - Prediction Improvement ;-)
consists of several groups of scientists from German universities and
institutions. The head of the joint project is Prof. Zschau, a well known
seismologist from the GeoForschungsZentrum (GFZ) Potsdam. On the Indonesian
side our partners are the Volcanological Survey of Indonesia (VSI) in Bandung
and more practical - the Volcano Technological Research Center in Yogyakarta
(BPPTK) http://www.vsi.dpe.go.id/mvohomepage.html
There all information of all Indonesian and international Science groups should
melt in one and support the Early warning and Hazard Mitgitation System.
3. LINUX present state
As you can imagine, an Early Warning System has to be founded on a stable
computing basis. At the moment the situation is that the system platform is
very diverse ranging from old DOS systems to WIN NT. My group, like many other
German geophysicists relies almost exclusively on LINUX platforms - at
least at home - however, in Yogya we have to be consider that staff of BPPTK is
not yet familiar with LINUX and therefore we have installed this summer again a
NT system. :-(
What are the computers used for? Actually, the data acquisition systems
operating as remote solar powered units all around and on top of Merapi use
their own firmware - not Linux. - but that is okay , so far. The data is then
send via 900 MHz telemetry to Yogya, where different groups have installed
arials, modems and their computers. The problems start now:
At the moment there is no common database or network cluster that could handle
the total of the data or would allow access from the international community. A
permanent internet connection does not exist in the BPPTK (costs). We have made
efforts now, to bring a LINUX system there that would dial in every day at
least for some hours. After the international researchers have
left, at the moment we have almost no access to our systems or data. Some
people wait months for CDs sent by mail !! This is oviously not EARLY WARNING
compatible, is it? The full retrieval of data would not even be neccessary if we
only could control the systems and supply our Indonesian partners with our
latest signal processing software (which is improved peramanently) and give
instructions for data acquisition maintanence. However, for this more
awareness understanding and schooling of staff in computing would be needed.
4. LINUX - the ideal state in the future
Ideally, there should be an open LINUX system consisting of :
1) a common database for all geophysical data on Merapi - structural data,
that means GIS related data as well as time series all recorded time series
from signals of Merapi. This should replace the very diverse computer
conglomerate that exists now. Efforts are being made at present to establish
a structure for a global volcanic database to which Yogya could be linked later.
2) A permanent internet connection, where the international scientists have
access to their recording and data processing systems. We could then:
- control the health of our systems
- improve data processing and react on events more quickly
- co-operate more effectively with local volcanological staff
- essentially improve the understanding of the volcano and come one
step closer to a real EARLY warning system
3) Education of the local volcanological staff - most of which are not
scientists - in network computing - and, above all, LINUX.
We are convinced that LINUX ist the better future. If now - in such a virgin
state - signals could be set in the right direction, not only the international
volcano community would benefit from that but above all the people of
Yogyakarta !
Dear Made, I hope this mail could give you a short impression, who we are and
what we are doing. I would be glad, if we could mutually support each other and
the LINUX and Open Source idea in Germany and Indonesia.
I remember very well that you mentioned a LINUX meeting in Yogya in September
with Mr. Habbibie as invited speaker. The German side,
especially the DFG, has spent a lot of money into the jMERAPI project,
especially for data acquisition systems of various kind (actually millions of
DM). However, they probably will not support a full network in BPPTK Yogya.
If our combined efforts and connections could help to guide some Indonesian,
German or International money into the volcanological work at Merapi - this
would be a great thing.
Hope to hear from you soon
Sven
