Abstrak: Penelitian ini bertujuan untuk mengevaluasi pemberian herbal daun kersen dan pegagan ke dalam air minum terhadap produksi dan kadar profil darah itik hibrida starter. Penelitian ini menggunakan 96 ekor itik hibrida (Peking x Khaki Campbell) umur 1 sampai 14 hari yang diberi pakan komersial (protein 21-23%) dengan 3 perlakuan dan 4 ulangan. Metode yang digunakan adalah Rancangan Acak Lengkap (RAL) yaitu : P0 (kontrol), P1 (5 mL campuran herbal), dan P2 (10 mL campuran herbal). Analisis data menggunakan uji ANOVA dan Uji Jarak Berganda Duncan. Hasil penelitian menunjukkan bahwa campuran daun kersen dan pegagan sebanyak 5ml dan 10ml mampu menurunkan pertambahan bobot badan. Campuran herbal daun kersen dan pegagan tidak mempengaruhi kadar profil darah itik hibrida., The study aims to evaluate the effect of giving Cherry leaves and Centella Asiatica herbs in drinking water on production performance and blood profile percentage of hybrid ducks. This study used 96 hybrid ducks aged 1 until 14 days which were given commercial feed (protein 21-23%) with 3 treatment groups and 4 replications. The method used was a completely randomized design (CRD) were : P0 (control), P1 (5 mL of herbal mix), and P2 (10 mL of herbal mix). Analyzed by Analysis of Variance (ANOVA) and Duncan's Multiple Range Test. The results showed that a mixtured of 5ml and 10ml of cherry leaves and gotu kola herb in drinking water was able to reduce body weight gain. The herbal mixture of Cherry leaves and gotu kola did not affect the blood profil of hybrid ducks.

Judul: The Effectiveness of Herbal Herbs in Drinking Water on the Performance of Peking Ducks 1–8 Weeks Old
Abstrak: Pemberian jamu herbal merupakan salah satu upaya yang dapat dilakukan untuk memperbaiki efisiensi pakan itik peking, sehingga diperoleh pendapatan yang lebih tinggi. Penelitian ini dilakukan untuk mengkaji efektivitas jamu kombinasi kencur, bawang putih, jahe, lengkuas, kunyit, temulawak, daun sirih hijau, dan kayu manis terhadap performa itik peking yang mendapat pakan komersial ayam broiler umur 1 hari-8 minggu. Penelitian menggunakan Rancangan Acak Lengkap (RAL). Itik peking sebanyak 150 ekor dibagi menjadi 5 kelompok perlakuan yaitu (P0 = kontrol, P1= air minum + jamu herbal 0,5%, P2 = air minum + jamu herbal 1%, P3 = air minum + jamu herbal 1,5%, dan P4 = air minum + jamu herbal 2%), dengan 3 ulangan. Peubah yang diukur terdiri atas konsumsi pakan, konsumsi air minum, bobot badan akhir, pertambahan bobot badan, konversi ransum, mortalitas, dan income over feed and duck cost (IOFDC). Data yang diperoleh dianalisis secara deskriptif. Berdasarkan tingkat mortalitas, konversi pakan, dan nilai income over feed and duck cost, penambahan jamu herbal 1,0% dalam air minum itik peking memberikan hasil yang terbaik., Giving herbal medicine is one of the efforts that can be done to improve the efficiency of feed for Peking ducks. This study was conducted to examine the effectiveness of a combination of kencur, garlic, ginger, galangal, turmeric, temulawak, green betel leaf, and cinnamon on the performance of Peking ducks aged 1 day-8 week. The study used a completely randomized design (CRD). 150 Peking ducks were divided into 5 treatment groups, namely (P0 = control, P1 = drinking water + 0.5% herbal medicine, P2 = drinking water + 1% herbal medicine, P3 = drinking water + 1.5% herbal medicine, and P4 = drinking water + 2 % herbal medicine), with 3 replications. The variables measured consisted of feed consumption, drinking water consumption, final body weight, body weight gain, ration conversion, mortality, and income over feed and duck cost (IOFDC). The data obtained were analyzed descriptively. Based on the mortality rate, the efficiency of feed use, and the value of income over feed and duck cost, the addition of 1.0% herbal medicine in drinking water for Peking ducks gave the best results.

Judul: Matriks Pascal dan Sifat-Sifatnya
Abstrak: Pascal matrices are matrices that their elements contain binomial coefficients. Pascal matrices can be built into three different types: symmetric Pascal matrix lower triangular Pascal matrix and upper triangular Pascal matrix This study aims to determine the characteristics of the Pascal matrices. The proof of characteristics shows that multiplication of a lower triangular Pascal matrix with an upper triangular Pascal matrix always yields symmetric Pascal matrix through three methods: matrix multiplication, Gaussian elimination, and equality of functions. In this study, matrix multiplication is the most effective method of proof. The proof of also shows that each of and has the same determinant value, that is one . Another characteristics of the Pascal matrix is that transpose of a lower triangular Pascal matrix is an upper triangular Pascal matrix and vice versa
