Wayang Kulit - Indonesia
Introduction
BMKG
INDONESIA
• Archipelago of 17,508 islands
• Area is 1.919.440 km2 (30% of lands and 70% of the seas)
• Seasons : Dry and Rainy
• Indonesia’s Population:
241,973,879 (2010 est.)
• Population growth rate: 1.45% (2010 est.)
Badan Meteorogi, Klimatologi dan Geofisika (BMKG)
• Meteorological, Climatological and Geophysical Agency
• BMKG have 5 National Regions Centre, with 119 Meteorological
stations, 21 Climatological stations, 31 Geophysical stations and
1 Global Atmosphere Watch (GAW)

The supporting Stations at BMKG
BMKG
The supporting Stations:
 202 Automatic Weather Station (AWS),
 79 Automatic Agroclimate Weather Station (AAWS),
 104 Automatic Rain Gauge Stations (ARG), and
 more than 4.000 conventional rain stations.
The conventional rain stations was observed by observer who
have not special education in meteorology or climatology.
That’s way we still need a lot of Automatic Rain Gauge (ARG)
to cover all of Indonesian's area and
obtaining high quality data.

Data Logger Design
BMKG
The ARG–BMKG’s data logger has made in a simple and
compact design. It is easy to operate and to process the
mounting.
The physical ARG–BMKG’s data logger is formed aluminium
profile based with dimensions 14cm x 16cm x 5cm. In front of
section of data logger are placed one LCD display with 16
characters - 2 lines, one matrix keypad 4 x 4 and two LED
indicators. At the bottom of data logger are placed a ports for
connectors, including: one connector to rain sensor, one
connector to the battery and two DB9 connectors to
transferring data with GSM modem and computer/notebook.
Power Supply Design
The Power Supply system design uses a solarcell 16-20 WP
and one Lithium ion dry battery 12 V with 17-18 AH capacity
for back up.
Application Program Design
This program serves to display a real time data measurement and
process download rainfall data from SD Card in a data logger.
The ARG-BMKG’s application programs made by Labview software
version 2011. The file Format is already formed the executable file
(.exe). This installation process is easy and does not require
additional programs.

GPRS wireless communication system
GPRS is a simple system and have a strong support from the cellular provider
in Indonesia where the ARG-BMKG are placed.
GPRS Modem use product of sierra wireless, Fastrack Xtend series. This
GPRS Modem can be programmed to facilitate the setting up and operation.
Laboratory Test
The measurement is done using a rain gauge from environdata
production with a resolution of 0.2 mm. Tests carried out in
Calibration Laboratory of BMKG, calibrators using from Hanil.Lab,
South Korea.
Based on the testing result, it is known that the ARG–BMKG’s data
acquisition for a rain gauge type tipping bucket can work well. With
the variation rain intensity 40 mm/hours (light rain/drizzel) to 250
mm/hours (heavy rain/showers), without any error counting or double
signal (cloning signal)
Field Test
BMKG
The field test was performed on climatological station at Semarang,
iCentral of Java. The field’s testing is done by comparing data from
3 rain gauges, installed on the same location and the same time. As
comparison’s data, we used data from the ARG-BMKG, AWSVaisala and observatory rain gauge (conventional).
Other locations:
1. Meteorological, Climatological dan Geophysical Academy (AMG)
2. Citeko Meteorological Station.
The data acquisition of these trials are in the graph.
Conclusions
1. BMKG’s technicians have successful developed an automatic
rainfall observation system-based on microcontroller ATMega
128, GPRS and web server systems.
2. This instrument names ARG-BMKG (Automatic Rain Gauge Meteorogical, Climatological and Geophysical Agency).
3. The ARG-BMKG have been tested through laboratory test and
field test with the result was satisfactory.
4. Hopefully, this engineering program can improve knowledge,
skill and trouble shooting every BMKG’s technician, so they
can support BMKG’s weather instruments maintenance
systems in Indonesia.
5. Next, we will develop the rain observation network to obtain
the high quality data.
