Anemia is a significant micronutrient deficiency problem among pregnant women, with a global prevalence of 41.8%. In Indonesia, 48.9% of pregnant women experience anemia, leading to health risks for both mothers and babies, including low birth weight and mortality. The provision of iron (Fe) supplement tablets is one of the solutions to reduce anemia rates. Despite government efforts, such as distributing Fe tablets, adherence among pregnant women at the Singandaru Public Health Center (UPTD Puskesmas Singandaru) in Kota Serang remains low. At the UPTD Puskesmas Singandaru, 58% of pregnant women were reported to have anemia during the January–December period in 2022, and this number increased to 60% in 2023, according to data from the health center. A study involving 16 respondents found that, based on the compliance with ANC visits, 10 respondents (62.5%) were categorized as non-compliant, while 6 respondents (37.5%) were compliant. In the category of iron tablet (Fe) consumption compliance, 11 respondents (68.8%) were non-compliant, while 5 respondents (31.3%) were compliant. Regarding family support compliance, 11 respondents (68.8%) were categorized as non-compliant, and 5 respondents (31.3%) as compliant. The role of healthcare workers showed that 3 respondents (18.8%) reported no involvement, while 13 respondents (81.3%) indicated the presence of support or assistance. The Chi-Square results for the four variables were as follows: compliance with ANC visits (p-value 0.551), compliance with Fe tablet consumption (p-value 0.119), compliance with family support (p-value 0.119), and the role of healthcare workers (p-value 0.247).
