Anemia during pregnancy is a major public health issue, especially in developing countries like Indonesia, contributing to maternal morbidity and adverse pregnancy outcomes. The second trimester, marked by increased iron needs due to plasma volume expansion and fetal growth, is critical for preventing anemia. Moringa leaves (Moringa oleifera), rich in micronutrients, may serve as an effective nutritional intervention to enhance hemoglobin levels in pregnant women. This study aimed to assess the impact of moringa leaf supplementation on hemoglobin levels in second-trimester pregnant women. Using a one-group pretest-posttest quasi-experimental design, the study was conducted at the Tadoy Community Health Center in Bolaang Mongondow Regency from October to November 2025, involving 25 pregnant women selected via purposive sampling. Hemoglobin levels were measured before and after the supplementation. Data analysis, including the Shapiro-Wilk test and Wilcoxon Signed Rank Test, indicated significant changes in hemoglobin levels (p = 0.000). The results showed a notable increase in hemoglobin levels post-supplementation, supporting the potential of moringa leaves as a safe, affordable, and effective intervention. This finding suggests that moringa leaves could be integrated into antenatal care and nutrition education to help prevent anemia in pregnant women.  

This study aims to examine the relationship between occupational nutrition and employee productivity through a systematic literature review. The background of this research lies in the increasing attention to workplace health and the growing evidence that nutritional status can influence physical performance, cognitive function, and work outcomes. A total of 74 articles were initially identified from databases such as PubMed, ScienceDirect, Google Scholar, and Garuda, of which 12 met the inclusion criteria and were analyzed further. The findings indicate that adequate intake of macronutrients and micronutrients—particularly iron, protein, and B vitamins—correlates positively with productivity levels. Interventions such as nutritional education, iron supplementation, and structured meal programs at the workplace showed measurable effects in reducing absenteeism and fatigue while improving concentration and efficiency. The study concludes that occupational nutrition plays a vital role in supporting workforce performance and suggests its integration into workplace health policies. Theoretical and practical implications are discussed, along with recommendations for future research
