In the end of rainy season, exactly on April 21th 2016, several areas in DKI Jakarta was flooded. This was triggered by heavy rains, which occurred in the area of Jakarta around the last 24 hours on 20 to 21 April 2016. According to the information from Geophysics, Climatology, and Meteorology Agency (BMKG), the highest rainfall was observed in Depok amounted to 202 mm/day, while in Jakarta, the highest rainfall was observed in Pasar Minggu amounted to 166 mm/day, both are included in the category of very dense (extreme).

What are performed ?

Pusdalops has a very important role in the event of crisis (disaster happening). The important role is a data and information center related to disaster that was happening. In the context of flooding in Jakarta, during floods, Pusdalops should be ready to provide an information and map of floods distribution in Jakarta every 6 hours (data updated every 06.00, 12.00, 18.00, and 24.00 WIB) through website of BPBD DKI Jakarta and so public know the flood information and avoid the affected area. The data are also the basis for BPBD to coordinate government institutions, business, and other institutions/organizations involve in the response of refugee needs and prevent the extent of flood impact.


HOT Indonesia and BPBD DKI Jakarta

In response to the Jakarta floods this year, HOT had the opportunity to contribute actively, including the utilization of Geo Data Collect (GDC) application for inundation and evacuation data collection. GDC is the field data collection application based on Android developed by HOT Indonesia. Application can be downloaded free, can be used for anything survey, not only in the field of disaster. In addition to text, GDC can accommodate the photo and video, so the result of field survey can describe the actual condition in the field.

In this year, driven by World Vision Indonesia (WVI), BPBD DKI Jakarta utilizes GDC for inundation and evacuation data collection. In addition to the feature quite complete, easy usage, and free; replication in GDC utilization for another disaster data collection (fire, tornado, brawl, etc) easily is the reason for the use of GDC in flood response by BPBD DKI Jakarta. Maybe the next question is “who people will gather the data?”. People who will collect the inundation and evacuation data are representative (both of staff and volunteer) villages and sub district affected by the floods. By collecting data using GDC, the report will be accepted by BPBD faster, with more accurate location information, so expect a response can be given more quickly and accurately. For the record, the report of inundation and evacuation processed and confirmed in advance by Pusdalops before it is disseminated to the public in the form of map of flood distribution.
