The paper presents an implementation of prototype based Early Warning System (EWS) to detect and provide early warning of Landslide activities. The main aim of this work is to implement the prototype with low cost sensor network. A simulation setup and a table based prototype setup was implemented to study the capability and effectiveness of the system. The setup consists of table based setup of landslide with multiple/changing angle from 30° to 90°. Multiple sensing elements including rain sensor to detect presence of rain, soil moisture sensor to detect the moisture content, temperature and humidity sensor to detect humidity in the environment and vibration sensor to detect movement in the soil was implemented. The data captured by the sensing element is transmitted to a microcontroller which sends early warning signal represented by LED, Buzzer and sending of SMS or call. Through the setup, it is found that the sensitivity of the moisture sensor is rather limited however the range of moisture content detected by the sensor is functional. The vibration sensor can be tuned to have high sensitivity to the movement of the soil however, a number of false positive outcome may be detected. The early warning system is still possible by using multiple sensing element and averaging over their outcomes. The early warning system using low cost components as prototype has been successfully demonstrated. This setup can be scaled up to a real field implementation after careful tuning.

Train Operation

The utility model of early warning system for train operation detects and analysis all the information from the weather detection, photoelectric detection, vibration sensor and signal of the tracks comprehensively. It determines the position of the train by the weighted coefficients and controls the interval signal and locomotive signal accurately. This system should be barely affected by the weather conditions, the results detected by this system are reliable, and it can ensure the train operates safely.

All disasters experienced by Indonesia in the last years has developed anawareness of the fragility and vulnerability. At this time, the disastermanagement is currently insufficient anymore. The disaster management gain anew dimension with UU 24/ 2007 and followed some related regulations.Mitigation program implemented by BPBD Banjarnegara includes Structuraland Non Structural Mitigation has been completed well. For example, disasterdatabase, installation of Early Warning System (EWS), information andsocialization, training and disaster simulation.In the future, mitigation will be focused on public education. Thegovernment should implement the hazard maps, environmental improvement,evacuation route, installation of low-cost EWS at all location, and relocation. inadditon, whole villages must become village disaster response (desa tanggapbencana).Key words : landslides; structural mitigation; non structural mitigation.
