Judul: The behaviour of the third lactation period fh dairy cows was given depolarization valves one motnh after calving
Abstrak: The behavior of FH dairy cows can be used to identify whether the animals are healthy or stressed as a result, it will have an impact on the milk production productivity. Friesian Holstein dairy cows may respond positively to additional feeding of depolarizing valves leaves. The goal of this study is to see how more depolarization valves affect dairy cow behavior throughout the third lactation phase. The Friesian Holstein dairy cows used in this study were three cows, which were divided into three treatment groups with one tail, namely P0 (complete feed of PT GGL), BKD ( complete feed of PT GGL and 100 g depolarization valves powder) and PKD (complete feed of PT GGL and 100 g depolarization valves pellet). The observed variables were frequency (e.g., eating, rumination, rest, locomotion, drinking, and elleminative). Data is presented in chart and analyzed descriptively. The result showed that the administration of depolarizing valves has volatile effect on all behavioral frequencies at each treatment level, namely by comparing (P0 and BKD), ( P0 and PKD) and (BKD and PKD).

Judul: Production of Colostrum and Colostrum Milk and Their Quality in Third Lactation FH Cows that Fed Depolarizing Katuk Supplementary Feed
Abstrak: Kolostrum adalah cairan limfa yang banyak mengandung imunoglobulin. Anak sapi yang baru dilahirkan sangat membutuhkan kolostrum. Daun katuk dipercaya dapat meningkatkan produksi susu. Penambahan katuk depolarisasi pada ransum sapi FH diharapkan dapat meningkatkan produksi kolostrum dan susu kolostrum dengan kualitas yang baik. Penelitian ini bertujuan mengetahui pengaruh pemberian pakan tambahan berupa katuk depolarisasi terhadap produksi dan kualitas kolostrum serta susu kolostrum pada sapi perah FH periode laktasi ketiga. Hewan yang digunakan dalam penelitian ini adalah sapi FH yang baru melahirkan sebanyak 3 ekor, yang akan dibagi pada 3 perlakuan dengan masing-masing perlakuan sebanyak satu ekor, yaitu kontrol (menggunakan pakan dari PT GGL), BKD (pakan GGL yang ditambahkan bubuk katuk depolarisasi), PKD (pakan GGL yang ditambahkan pellet katuk depolarisasi). Katuk depolarisasi diberikan sebanyak 100 g/ekor/hari. Hasil pengamatan disajikan deskriptif. Peubah yang diamati adalah konsumsi pakan sebelum dan setelah beranak, produksi dan kualitas kolostrum serta susu kolostrum. Hasil penelitian menunjukkan bahwa pemberian katuk depolarisasi tidak dapat meningkatkan konsumsi pakan, produksi kolostrum maupun susu kolostrum, dan kualitas susu kolostrum sapi Friesian Holstein laktasi ketiga. Peningkatan kualitas terlihat pada kolostrum sapi FH yang diberikan katuk depolarisasi berbentuk bubuk dan pellet., Colostrum is a lymph fluid that contains a lot of immunoglobulins. Newborn calves need colostrum. Katuk leaves are believed to increase milk production. The addition of depolarizing valves to the ration of FH cows is expected to increase the production of colostrum and colostrum milk with good quality. This study aims to determine the effect of supplementary feeding in t he form of depolarizing catuks on the production and quality of colostrum and colostrum milk in FH dairy cows during the third lactation period. The animals used in this study were FH cows that had just given birth as many as 3 heads, 2 which would be divided into 3 treatments with one treatment each, namely control (using feed from PT GGL), BKD (GGL feed added with depolarizing katuk powder), PKD (GGL feed added with depolarizing valve pellets). The depolarizing valve was given as much as 100 g/head/day. The results of the observations are presented descriptively. The observed variables were feed consumption before and after giving birth, production and quality of colostrum and colostrum milk. The results showed that giving a depolarizing catuk could not increase feed consumption, production of colostrum and colostrum milk, and the quality of colostrum milk of third lactation Friesian Holstein cows. The quality improvement was seen in FH cow colostrum which was given depolarizing catuk in powder and pellet form.

Judul: Mencari Aproksimasi Akar-Akar Polinomial Kompleks Dengan Algoritma Weyl
Abstrak: Mencari akarMakar polinomial dengan menggunakan algoritma Weyt. Algoritma WeyJ merupakan algoritma rekursif yang proses kerjanya dapat diana10gkan dengan algoritma Bisection. Karena algoritma Weyl bergerak dalam bidang kompleks maka memerlukan nilai awal hempa bujur sangkar. Dalam proses penyempitan bujur sangkar tersebut algoritma Weyl memerlukan algorittna Turan untuk menentukan jarak antara suatu titik dengan akar polinomial yang terdekat dengan titik tersebut. Karena apabiJa jarak tersebut temyata lebih hesar dari Yl panjang diagonal bujur sangkar yang diamati maka bujur sangkar tersebut tidak memuat satu pun akar polinomial. Untuk seJanjutnya bujur sangkar tersebut diabaikan. Sebaliknya apabila jarak yang diperoleh lebih keeil dari \6 panjang diagonal bujur sangkar yang diamati, maka bujur sangkar tersebut yang akan diperkeciL
