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: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
