Judul: Kondisi Fisiologis (Hematologi, Denyut Jantung, Frekuensi Respirasi, dan Suhu Tubuh) Sapi Perah Kering Kandang di KPBS Pangalengan
Abstrak: The objective of this research was aimed to study the physiological condition of Friesian Holstein (FH) dairy cattle during dry period in KPBS Pangalengan. KPBS Pangalengan is located at 1 000–1 420 meters above sea level with temperature about 12-28 °C per year and humidity 60-70% per year. Environmental condition in KPBS Pangalengan will affect physiologic of dairy cattle during dry period. Physiological condition is very important to know the health condition of dairy cattle. This research used 46 dairy cattle during dry period are clinically healthy. Measurement parameter fisiological was done at morning, noon, and evening, then the result obtained calculated average. The range of heart rate, respiration frequency, and body temperature were 52.8−70.2 times/min, 18.9−36.6 times/min, and 37.6−38.6 °C. The range of hemoglobin, hematocrit, erythrocytes, and leukocytes were 9.3−11.3 g/dl, 30.4−36.6%, 6.5−8.70 million/μl, and 7.4−12.8 thousand/μl. The range of differential leukocyte covering lymphocyte, neutrophils, monocytes, eosinophils, and, basophils, were 29.60 ̶ 55.60%, 28.80 ̶ 56.20%, 0.30 ̶ 4.30%, 5.50 ̶ 19.7%, and 0.00 ̶ 0.00%. The ratio of neutrophils/lymphocytes obtained ranges 0.45 ̶1.91. In general, measurements of physiologic condition of dairy cattle during dry period is at normal conditions based on the climate in the region. The value is expected can be used as reference physiological of dairy cattle during dry period in KPBS Pangalengan.

Judul: Status Kecernaan Pakan dan Produksi Susu Induk Sebagai Indikator Pertumbuhan Pedet pada Sapi Perah (Friesian Holstein) di KPBS Pangalengan
Abstrak: Status of feed digestibility, milk production, and growth in cow and calf are indicator of performance improvement milk production and cow population in the dairy farm area. Study about the relation between feed, digestibilility, and performance (milk production and growth of calf) in the dairy farm area have not much done. Pangalengan is a central of dairy farm that coordinate by KPBS. The purpose of this research is to know about status of feed digestibility, milk production, and growth of calf in public farm KPBS Pangalengan. Sixteen weaning cows were used for feed digestibility and milk production observation, also sixteen calfs were used for body weight observation. The observational data of the overall parameters was analyzed descriptively then statistically using analysis of variance (Anova) method. Status of feed digestibility and milk production of dairy cows in KPBS Pangalengan can be used as indicators of the growth calves. Percentage of feed digestibility which were dry matter 81.40%, crude protein 89.29%, crude fat 95.12%, crude fiber 63.54% and ash 77.34% show the feed digestibility was good. Milk production showed good quality in the first 8 weeks lactation which was 18.74 liter/cow/day. Growth of body weight in calf was 0.2 kg/calf/day. Based of these result, Dairy farm KPBS Pangalengan have good management for dairy cows that would keep the cows healthy and productive.

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
