In Indonesia, 2018 stated that 48.9% of pregnant women had anemia, West Java province, namely 63.25%. Sukabumi Regency is 11.2%, and in the village of Cibunar Jaya in 2021 it is 33.9%. Efforts made to prevent anemia, namely consuming Fe tablets, can also be given non-pharmacological therapy, namely red guava juice. To determine differences in hemoglobin levels before and after administration of red guava juice in third trimester pregnant women.

The average hemoglobin level before giving red guava juice was 10.823gr/dl. After giving red guava juice for 7 days, the average hemoglobin level was 13.993gr/dl. The results of the study with the parried T test p-0.001 so that the value of p<0.05. There are differences in hemoglobin levels before and after administration of red guava juice in third trimester pregnant women.

Di Indonesia 2018 menyatakan 48,9% ibu hamil mengalami anemia, provinsi Jawa Barat yaitu 63,25%. Kabupaten Sukabumi sebesar 11,2%, dan di desa Cibunar jaya tahun 2021 sebanyak 33,9%. Upaya yang dilakukan dalam pencegahan anemia yaitu mengkonsumsi tablet Fe, dapat juga diberikan terapi non farmakologi yaitu pembeian jus Jambu biji merah. Untuk mengetahui perbedaan kadar hemoglobin sebelum dan sesudah pemberian jus jambu biji merah pada ibu hamil trimester III. Penelitian ini menggunakan rancangan Pre-eksperimetal, designs One-Group Pretes-Postest dalam waktu 7 hari. Sampel 30 orang ibu hamil trimester III usia kehamilan 33 mgg – 35 minggu yang memenuhi kriteria inklusi dan eksklusi dengan teknik purposive sampling.
