Iron deficiency anemia (ADB) is anemia that arises due to reduced iron supply for erythropoiesis, due to empty iron stores (depleted iron stores) which ultimately results in reduced hemoglobin formation. This study aims to determine the effect of giving blood supplement tablets on HB levels in female students suffering from anemia at SMAN 1 Tambakboyo, Tuban Regency. The research design used a pre-experiment using a one group pre test post test approach, with a total sampling technique on a population of 34 female students suffering from anemia in class X and analyzed using the Wilcoxon test. The instruments in this research were Standard Operating Procedures (SOP), hemoglobin level observation sheets and Easy Touch GCU brand hemoglobin measuring equipment. The results of the study showed that the average HB level before 10.17 g/dl and after 15.46 g/dl given blood supplement tablets was normal. The results of the Wilcoxon test obtained a significant value of p=0.000 (p<0.05), which means that there was a significant difference in the HB levels of class X female students before and after being given blood supplement tablets. Health workers, especially in school health offices, should provide blood supplement tablets at the right time so that female students can take the blood supplement tablets regularly and finish them.

Menstrual hygiene is an important component of personal hygiene that plays a significant role in an individual's health behavior, helping to prevent disorders in reproductive organ function. This study aims to determine the effect of health promotion on the level of menstrual hygiene knowledge among children aged 13–15 years. The study design used a pre-experimental approach with a one-group pre-posttest design. The population consisted of 110 respondents, and using simple random sampling, 83 respondents were selected. Data for this study were collected using a knowledge level questionnaire. After tabulation, the data were analyzed using the Wilcoxon test with p < 0.05. The results showed that nearly all female students (108, or 98.2%) had insufficient knowledge of menstrual hygiene before receiving health promotion. Almost all female students after receiving health promotion had adequate knowledge of menstrual hygiene, totaling 88 (80.0%). Based on the above results, the effect of health promotion on the level of knowledge of menstrual hygiene among children aged 13-15 years was found to be p = 0.000 (p < 0.05). This indicates that health promotion has an effect on the level of knowledge about menstrual hygiene among girls aged 13–15 years. Therefore, it is hoped that female students will always maintain their genital hygiene by practicing proper personal hygiene in accordance with the guidelines provided by healthcare professionals, especially during menstruation.
