Volcanic eruptions can be detected through several signs. The Indonesian National Disaster Management Agency (BNPB) reports that there were 156 volcanic eruptions in Indonesia from 2010 to 2021. Latest on 2021 an eruption of Mount Semeru caused 10,395 people to flee, 104 were injured, and 51 died. The BNPB often experiences problems in carrying out mitigation, evacuation, rehabilitation, and reconstruction in disaster areas. On average, the search and evacuation process for victims takes about 3-7 days so the percentage of finding victims of a disaster is only about 50%. The solution offered is a combination of radio transmitting with Auto Packet Reporting System (APRS) technology as a media for determining evacuation locations and Slow-Scan Television (SSTV) as a media for sending sounds and images of locations around the disaster called Radio All in One (RAIONE). Using the Prototype method, this research has been tested for about 7 months with improvements that are always made and the results of this research are the maximum distance that can be covered about 20 km with a minimum height of the central antenna between 7-10 meters so that can increase the effectiveness of time in SAR operations to finding victims alive in a disaster can increase to 75% and speed up the SAR operations to 1-2 days because there was an acceleration in the determination of search and evacuation locations in the Blank Spot Areas which reached 91.30%.
