This study uses secondary data from the 2017 National Social Survey (Susenas), this study aims to prove the determinants of household food security in rural areas in Indonesia in 2017.The cross-sectional study design where data was collected at the same time, and obtained by the Linear Probability model (LPM) logit and probit models. Estimated results with probit tests show food security is positively related to education level, economic status and raskin with estimated coefficients of 0,112, 0.118 and 0,218. The level of education and economic status is significantly related to food security (p value <0,01), but raskin is not significant (p value=0.561). Estimation results show that food security is negatively related to work status, number of family members and PKH with estimated coefficients of -0,188, -0,650 and -0,091. Working status, the number of family members and PKH are significantly related to food security.
