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: Evaluation of Acceptance and  Compliance with Iron-Folic Acid (IFA) Tablets for Adolescent Girl in Bogor
Abstrak: Anemia menjadi salah satu masalah gizi utama di Indonesia. Data Riskesdas 2018 menunjukkan kejadian anemia sekitar 32% pada kelompok usia remaja 15 – 24 tahun. Suplementasi zat besi menjadi salah satu upaya pemerintah dalam mengatasi anemia remaja. Penelitian ini bertujuan mengkaji penerimaan dan kepatuhan konsumsi tablet tambah darah pada remaja putri di Kota Bogor. Desain penelitian merupakan cross-sectional study yang dilakukan di tiga sekolah dengan total subjek sebanyak 341 siswi. Subjek dipilih berdasarkan simple random sampling. Data kepatuhan, penerimaan, dukungan orang tua dan dukungan guru dikumpulkan melalui pengisian kuisioner secara mandiri oleh siswi. Uji hubungan kepatuhan konsumsi TTD dengan dukungan guru serta tingkat kepatuhan TTD dengan dukungan orang tua menggunakan chi-square. Hasil penelitian menemukan bahwa siswi menerima 4 tablet per bulan sebesar 83%, siswi yang menerima kurang dari 4 tablet per bulan sebesar 5,9% dan siswi yang tidak menerima tablet tambah darah sama sekali sebesar 11,1%. Sebanyak 39% siswi tidak patuh konsumsi TTD dan sebanyak 31,4% siswi tidak sama sekali konsumsi TTD. Sebagian besar siswi kurang mendapat dukungan guru dan dukungan orang tua terhadap konsumsi TTD. Dukungan guru dan dukungan orang tua memiliki hubungan yang signifikan terhadap konsumsi TTD siswi (p<0,05)

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
