Assessment of the community capacity conducted by qualitative interactive model and analyze data use a quantitave models. For the calculation of total risk carried out by using risk analysis model. Result of the vulnerability showed that highest vulnerability is located in RT 03 and lowest vulnerability is located in RT 01.
