Indonesian territory has a high potential for geological disasters such as volcanic eruptions, earthquakes, landslides, tsunamis. To provide disaster protection it is necessary to carry out mitigation which is a preventive action to minimize the negative impact of natural disasters that occur. In areas where the GSM network is large enough, the disaster information system is being replaced by the advanced technology developed by the GSM protocol. However, if there is a telecommunication disruption and when all the regular communication infrastructure is down as well as geographic conditions are not covered by the public network. So one of the effective media in an effort to create an ideal information system is radio communication, which is widely used by Amatir Radio members who are widespread in Indonesia which can be accessed by all levels of society with a wide range. So this research was conducted by utilizing the VHF spectrum radio wave transmission with a frequency of 144 MHz as a transmission medium to convey information signals on landslide disaster mitigation for the community. From the system integration measurements were taken to obtain the value of the ground motion sensor and the range of radio wave transmission.
