During the rainy season several rivers in the Bandung Basin area overflowed and inundated several sub-districts both in the city of Bandung and the surrounding cities and districts. In the 2017 activity there will be additional observation points by placing several AWS in several regions of Bandung Basin, both West Bandung Regency, Bandung Regency, Bandung City and Cimahi City. This was done to improve the weather monitoring system in the system of flood early warning not only in the Majalaya region, but throughout the Bandung basin area. This activity will involve several parties, including the community itself and the local government, in this case the West Java BPLHD will collaborate in the provision of AWS (Automatic Weather System) and the development of a flood warning system. This 2017 community service activity begins with the design and assembly of AWS. Using Arduino as a control base (Figure 5.1). The AWS draft is basically the development of the previous design used in Community Service (PM) in 2015 and 2016. At PM 2017, the controller unit was overhauled and rearranged using Perforated PCB (Printed Circuit Board). Keywords: Flood, weather monitoring, Automatic Weather System
Application of appropriate technology
The first problem in this activity is AWS care or repair. AWS It has been installed often experiencing interference so it does not function normally. Maintenance and repair AWS requires human resources, material and no time A little, so it's rather difficult to do. Besides there is no special fund allocation for this need, so care or repairs are carried out along with activities Nearest AWS installation. The second problem which is also an obstacle is the period Active GSM card and limited SMS package. This requires it to do Release pulses and registration of packages every month for each AWS. Even though AWS has programmed to be controlled remotely, but if charging pulses missed or AWS Had not work for a long time, then activation must be done manually By moving the card to a mobile device. This is very difficult especially If the AWS position is quite far from ITB. The first problem solution is to design reset AWS to be more modular and easier to repair by local partners. This is of course must be accompanied by Debriefing or Repair Training AWS. Alocation is needed Special funds for treated care and repair activities installed, so Repairs can be done at any time. As for the second problem, the solution is by submitting a proposal to a certain cellular provider to obtain a SIM card Special which has a very long active period or even a free SMS package. Other solutions is to replace the SMS communication system using another communication system Does not require pulses or package registration, for example Long Range WiFi.
