Judul: Food Consumption, Knowledge, Attitudes, and Practices related to Anemia and Iron-Folic Acid Supplementation on Anemia Status of Adolescent Girls
Abstrak: Adolescent girls are at high risk of anemia due to unmet nutritional needs and low compliance to the government's folate-iron supplementation program. This study investigates the differences in food consumption, knowledge, attitudes, and practices related to anemia and supplementation among high school and vocational school students. Data was collected from 52 students in Ciamis, using secondary data from Empowerment of Weekly Folate-Iron Supplementation Program in High Stunting Areas. Significant differences (p<0.05) were found in weekly consumption of vegetables and fruit. High school students had higher average frequencies of iron-rich and iron-inhibiting food consumption, although not statistically significant (p>0.05). Both groups had inadequate intake of energy, protein, vitamins A, C, B12, folate and iron. Knowledge scores were higher among high school students, but not significantly different (p=0.778). Attitude scores were almost similar and positive in both groups. Vocational school students showed better compliance with a higher average number of tablet consumptionand statistically significantly different (p=0.01) from high school students. Hemoglobin levels were higher in high school students, but not significantly different (p>0.05). No significant correlation was found between energy, protein, vitamins A, C, B12, folate, iron intake, knowledge, attitude, and the number of IFA tablets towards anemia status (p>0.05)., Adolescent girls are at high risk of anemia due to unmet nutritional needs and low compliance to the government's folate-iron supplementation program.

Judul: The Correlation Between Knowledge of Anemia and Adherence to Iron Folic Acid (IFA) Supplement Consumption by The Adolescent Girls with Anemia in Kupang District.
Abstrak: Anemia menjadi salah satu masalah gizi yang sering terjadi pada remaja. Penelitian ini bertujuan mengetahui hubungan pengetahuan anemia dan kepatuhan mengonsumsi tablet tambah darah dengan anemia pada remaja putri di Kabupaten Kupang. Penelitian ini menggunakan data sekunder dari data penelitian Better Investment for Stunting Alleviation (BISA). Desain penelitian ini adalah cross sectional dengan jumlah subjek 1.610 siswi dari SMA dan SMK. Hasil penelitian menunjukkan sebanyak 379 (23,5%) siswi memiliki tingkat pengetahuan anemia dalam kategori baik dan 245 (15,2%) siswi patuh mengonsumsi tablet tambah darah. Pengetahuan anemia berhubungan signifikan dengan kepatuhan mengonsumsi TTD 0,154 (p=0,000). Pengetahuan anemia berhubungan signifikan dengan anemia 0,073 (p=0,003). Kepatuhan mengonsumsi TTD berhubungan signifikan dengan anemia -0,102 (p=0,000). Remaja putri perlu memperhatihan kecukupan zat besi agar memiliki kadar hemoglobin dalam rentang normal., Anemia is among nutritional problem that often occurs in adolescents. This study aims to determine the correlation between knowledge of anemia and adherence to IFA supplement consumption by adolescent girl in Kupang District. This study uses secondary data from Better Investment for Stunting Alleviation (BISA). This research design is cross sectional with the number of subjects 1.610 students form Senior High School and Vocational High School. The result showed 379 (23.5%) subjects had good level of anemia knowledge and 245 (15.2%) subjects complied to IFA supplement consumption. Knowledge of anemia significantly correlated with adherence to IFA supplement consumption 0.154 (p=0.000). Knowledge of anemia significantly correlated with anemia status 0.073 (p=0.003). Adherence to IFA supplement consumption significantly correlated with anemia status -0.102 (p=0.000). Adolescent girls need to pay attention to the adequacy of iron to have normal hemoglobin levels.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
