Abstract

Background: Anemia is a nutritional problem in children, pregnant women, teenagers, and women of childbearing age. The prevalence of anemia in Indonesia in 2018 among young women was 48.9%. Bay leaves are widely known in various culinary and traditional medicine in Indonesia. Objective: This study analyzes the iron (Fe) and zinc (Zn) content in bay leaves (Syzygium polyanthum) growing in Karanganyar, Indonesia. Method: This research is an observational descriptive experiment with a laboratory approach carried out through a series of experiments. An Atomic Absorption Spectrophotometer (AAS) is used to analyze iron levels. Results: This research shows that the average concentration of Fe in bay leaves growing in Karanganyar is 294.28 mg/L per 100 grams of bay leaves. Meanwhile, the average concentration of Zn in bay leaves is 15.19 mg/L per 100 grams of bay leaves. According to TKPI 2017, bay leaves contain around 44.1 mg of iron per 100 g. Apart from that, the results of research conducted by Suharni 2021 show that 100 g of bay leaf extract contains around 30.09 mg of iron. Comparison with other plants shows that bay leaves contain much more iron and zinc. Higher than plants such as Moringa leaves. As an example of another plant that is often consumed, Moringa leaves have a lower iron and zinc content, namely 6 mg Fe/100 grams of Moringa leaves and 0.6mg/100 grams of zinc. In addition, this research opens up opportunities for application to experimental animals such as mice, which can be given bay leaf powder to understand its impact on iron and zinc levels in their bodies. Conclusion: The average test concentration of Fe in bay leaves is 294.28 mg/L. Meanwhile, the average concentration of Zn in bay leaves is 15.19 mg/L.

Abstract

Infectious diseases are the leading cause of child mortality in Indonesia, yet many deaths can be prevented through immunization. The 2023 Indonesian Health Survey reported a national full basic immunization coverage of only 35.8%, a decrease from 57.9% in 2018 and far from the 100% target. Surakarta City achieved a coverage of 98.34% in 2023, showing strong regional commitment, although it still does not fully meet national goals. This study analyzes the influence of the Theory of Planned Behavior (TPB) on the use of immunization services for infants in Surakarta. Using a cross-sectional design, 200 mothers with infants aged 12–24 months were selected through multistage random sampling. Independent variables include intention, attitude, subjective norm, and perceived behavioral control; the dependent variable is the use of infant immunization services. Data were collected via structured questionnaires and analyzed using linear regression and path analysis. The study found that intention directly affects the use of immunization services (b=0.20; 95% CI=0.07 to 0.33; p<0.00). Attitude, subjective norm, and outcome evaluation indirectly influence immunization service use through intention. The path model demonstrated good fit (CFI = 0.979; TLI = 0.964; RMSEA = 0.079; SRMR = 0.037). Intention plays a crucial role in the use of immunization services, with attitude, subjective norm, and outcome evaluation affecting use through intention. The study model shows good fit. Increasing immunization uptake should focus on strengthening intention through positive attitudes, social norms, and education.
