Prototype of the Real Time Decision Support System for Flood Early Warning at Brantas River Basin

Flood disasters still occur regularly and continuously in Indonesia. This purpose of this study is an attempt to suppress losses from floods, flood prevention and suppression of expenses incurred in monitoring tools that were made earlier. This study resulted in a prototype decision support system of early detection of flooding in real time using a data logger based on the Global System for Mobile Communications (GSM). Parts of the system hardware is a monitoring station watershed conditions that have sensor modules connected to the datalogger based on GSM. Sensor modules will monitor three parameters, elevation of river water level, temperature and humidity. Detection result of each sensor module data is processed by a datalogger and then the it will be sent to the master station server via SMS Gateway. Decision support information system is web-based so it can be accessed through the Internet by specific users and general users. The advantages of this system is designed to flood warning information dissemination can be done quickly because the spread through SMS and internet. The information system is named Flood Early Warning System (FEWS). Results from the study show that the data acquisition from the sensors and sent to the master station server and web graphic display shows the system to function properly.
