Background : The cause of the problem of anaemia is a lack of intake of nutrients. Efforts made by the government to overcome this include the Supplemental Feeding Programme. The purpose of this study was to analyse the effect of additional food for pregnant women in the form of biscuits modified with pumpkin, moringa leaves, and peanuts on increasing haemoglobin levels and the size of the upper arm circumference in pregnant women as an effort to prevent stunting. Methods: A quasi-experimental study (quasi-experimental design) with a non-group pretest-posttest design, namely comparing haemoglobin levels and upper arm circumference of pregnant women before and after the intervention. The intervention given was giving biscuits modified from moringa leaf flour, peanuts and pumpkin flour as much as 60 g (6 pieces) every day to pregnant women. Results : Modified biscuits contain 269.1 kcal of energy, 4.9% protein, 13.1% fat, 27.72% carbohydrates, vitamin C: 70.2 mg, and vitamin A: 6.2 mg. The average Hb level of pregnant women after the intervention was 11.5 g/dL, compared to 10.9 g/dL before the intervention. The average size of the upper arm circumference of pregnant women has also increased from 26.8 cm to 27.8 cm. Conclusion: The modified biscuits meet the requirements of SNI biscuits and meet the requirements for PMT for pregnant women. Giving biscuits increased the average hemoglobin level of pregnant women by 0.82 g/dL and the average size of the upper arm circumference by 1.0 cm and reduced the prevalence of anemia in pregnant women by 60%.
