The Communication Radio with Solar Power for Natural Disasters
Indonesia as the archipelagic state which is prone to disasters and many disasters occurred, claimed a large numbers of casualties.There are three potential disasters in Indonesia, namely natural disaster, non-natural disaster, and social disaster. During a disaster, the delivery of conditions in the place to be informed is necessary to all citizens so that the decision can be quickly taken to protect them. In a disaster system management, the communication is needed starting from planning, mitigation, and emergency response to rehabilitation. One of the technologies used is a 2 meter band transceiver radio working at frequency of 144 MHz that transmits and receives information in the form of audio/analog, widely used by the community organization such as ORARI and RAPI. One of the weaknesses of this system is the battery availability or power supply.To fix these weakness, the radio communication is powered by the battery/accumulator which is equipped with solar cell, solar cell is used to charge the battery/accumulator by utilizing the sunlight.
