Design technology in wireless mesh network system for eruption disaster mitigation of Merapi volcano

Indonesia is one country in the world that has the biggest natural disaster risk. That is because the position of Indonesia which is located at the confluence of three plaques Indo-Australian, Eurasian and Philippines. One of the disasters that often occur is the eruption of a volcano that is indeed one of the most active volcanoes in the world located in Indonesia called Merapi volcano. Currently, monitoring a volcano still rely on measurements on site and remote monitoring using camera and outposts near Merapi volcano. It is becoming less effective due to the efficiency and effectiveness of the key staple of disaster mitigation process. This paper provides a new approach to monitor the state of the Merapi based on ambient temperature in Merapi using wireless mesh network system based on Zigbee modules, effectiveness and reliability found in volcano monitoring which the level of reliability of a particular node at a distance of 200m and can perform data transmission when multiple nodes are damaged and the data is sent successfully.
