Abstract

Latar belakang: Kedelai adalah hasil pangan jenis kacang-kacangan yang sangat kaya akan nutrisi yang bermanfaat bagi kesehatan manusia. Tujuan: Untuk mengetahui keberadaan zat besi dan kadar zat besi dalam sari kedelai. Metode: Analisis kualitatif menggunakan pereaksi NaOH, K4[Fe(CN)6] dan K3[Fe(CN)6] dan analisis kuantitatif menggunakan spektrofotometer UV-Visibel pada panjang gelombang 248.3 nm. Hasil: Sari kedelai mengandung zat besi yang dibuktikan melalui analisis kualitatif menggunakan pereaksi NaOH, K4[Fe(CN)6] dan K3[Fe(CN)6] yang menghasilkan masing-masing endapan hijau, biru dan coklat yang artinya mengnadung zat besi. Persamaan regresi linear larutan standar besi adalah Y = 0.0154x  +  0.1555 dengan korelasi (R2) sebesar 0.9981. Kadar zat besi dalam sari kedelai adalah 56.48 mg/ml dan termasuk dalam kelompok produk yang memiliki kadar zat besi yang cukup tinggi. Kesimpulan: Sari kedelai mengandung zat zat besi dengan kadar sebesar 56.48mg/ml.

Abstract

Medical students are highly susceptible to GERD due to the intense pressure and hectic pace of medical education. Risk factors for GERD in medical students include inadequate knowledge, poor dietary habits, frequent coffee consumption, and high stress levels. This cross-sectional study enrolled 250 students. Data were analysed using chi-squared test and logistic regression. The results showed a significant association between knowledge (0.000), diet (0.000) and coffee consumption (0.002) with GERD in medical students. Stress was not a significant risk factor in this study (0.127). Regression modelling showed that improving diet can minimise the risk of GERD by a factor of one. There is a need to improve diet and lifestyle in medical students to minimise GERD.
