This purpose of this research is to reveal the
social benefits and costs felt by the communities affected
by earthquake and liquefaction mitigation in Sigi Regency.
This research is a type of qualitative research using the
ethnomethodology method as a way to understand how the
social benefits and costs are felt by the community after
earthquake and liquefaction disasters. Data obtained by
conducting in-depth observations and interviews in person
and by telephone for 4 months, as well as documents, and
conducting literacy reviews from various sources.The
results showed that in analyzing social benefits and social
costs, we looked at the aspects of economic losses, physical
losses, psychological losses, and social losses. Disasters
cause social losses in terms of destroying the order of life in
society where victims experience psychological problems
due to loss of property, loss of residence, loss of family, and
loss of meaning in life. Behind that disaster also has social
benefits, namely the creation of emotional bonds in the
form of mutual help and spiritual benefits. The existence
of disaster mitigation is expected to be an effort to reduce
disaster risk, both through physical development as well as
awareness and increased capacity to face disaster threats.
