Malaria prevention during pregnancy is achieved through the use of insecticide-treated mosquito nets, which can be obtained through integrated ANC services that include malaria services. Socio-cultural factors are determinants of pregnant women's access to ANC services and obtaining insecticide-treated mosquito nets. Kodi Utara District is one of the malaria-endemic areas on Sumba Island. Pregnant women who live in this area are at high risk of being infected with malaria, but pregnant women's access to mosquito nets and their utilization are still low. This study aims to develop a model of community empowerment based on socio-culture to increase the use of insecticide-treated mosquito nets in the Kodi Utara District. The design in this study used a mixed-methods method with an exploratory sequential design with pregnant women as the research subjects. The number of samples in the study was 144 pregnant women, namely 71 pregnant women in the control group and 73 pregnant women in the intervention group. The effect of the intervention was known using difference-in-difference analysis. After the identification of socio-cultural and forms of community participation related to the use of insecticide-treated mosquito nets, a community empowerment model was then prepared based on the results of the identification and then the intervention was carried out for 2 months in the intervention group there was an increase in maternal knowledge by 21.13% and the practice of using mosquito nets correctly by 20.83% better than the control group. The researcher suggests that in developing a malaria prevention strategy in pregnancy, consideration should be given to socio-cultural factors and actively involving every component of society. In addition, in terms of regulation, it is necessary to make derivative rules regarding education on the use of insecticide-treated mosquito nets for pregnant women, which is carried out during routine mosquito net distribution at integrated malaria services for KIA in West Sumba Regency
