Hubungan Komsumsi Energi, Zat Besi (Fe) dan Zat Seng (Zn) dengan Prestasi Belajar pada Siswa SMAN 1 Kabangka Muna Tahun 2025

Abstrak

The main problem faced by Indonesia in the field of education today is the low learning achievement among school-aged children. Energy intake, iron (Fe), and zinc (Zn) are important indicators that play a crucial role in supporting brain growth and development. This study aims to examine the relationship between energy, iron (Fe), and zinc (Zn) intake with learning achievement among students at SMAN 1 Kabangka. This research employed a quantitative analytic observational design with a cross-sectional approach. The study was conducted in March 2025 at SMAN 1 Kabangka. Sampling was carried out using a random sampling technique among students of grades X and XI, with a total of 98 respondents determined using the Lemeshow formula. Data on energy, iron (Fe), and zinc (Zn) intake were collected through a 3x24-hour food recall form. Data were analyzed using the chi-square test. The results showed that energy intake (p=0.007) and iron intake (p=0.044) were significantly associated with learning achievement, while zinc intake (p=0.619) showed no significant relationship. Conclusion: There is a relationship between energy and iron (Fe) intake with learning achievement, whereas zinc (Zn) intake has no significant association with learning achievement.
