Judul: Total dan Diferensiasi Leukosit Sapi Pejantan Unggul dengan Body Condition Scoring (BCS) Tinggi
Abstrak: Bull were sperm producer for artificial insemination. Physiological data such as leukocytes differentiation were important for supporting routine health monitoring. The objective of this study is to get the profile of leukocytes from high-level body condition scoring (BCS) of bull. The 30 blood samples of 3 breed bull (Simmental, Brahman, Friesian Holstein) were collected through coxygeal vein and calculated using microscope eye-piece camera instrument. The results showed that bull in A group (age <5 years) had higher total leukocytes than bull in B group (age >5 years). Average value of total leukocytes, eosinophil, neutrophil, basophil, lymphocyte, and monocyte of bull in A group were 7764 cell/μL, 411 cell/μL, 4150 cell/μL, 109 cell/μL, 2892 cell/μL, and 204 cell/μL consecutively. While the average value of total leukocytes, eosinophil, neutrophil, basophil, lymphocyte, and monocyte of bull in B group were 6832 cell/μL, 437 cell/μL, 3771 cell/μL, 71 cell/μL, 2363 cell/μL, and 192 cell/μL consecutively. Leukocytes morphology between breed and ages also shown the similar shape.

Judul: Profil Body Condition Score (BCS) Sapi Perah di Wilayah Koperasi Peternakan Sapi Bandung Utara (KPSBU) Lembang (Studi Kasus)
Abstrak: Body Conditon Score (BCS) is a method to define or interpret the livestock’s weight and its physiological state. This case study was conducted in Sukajaya which belongs to the area of North Bandung Dairy Farmer Cooperation by observing the condition of dairy cattle types Friesian Holstein. A hundred lavtation of dairy cattle was used in this case study.The scoring was based on 1(emaciated) to 5(very fat) by the interval degree of 0.25. In Sukajaya farming society, the body condition score at the early fase of lactation was 3.106+0.354, then decrease at the peak milk fase 2.981+0.268. This score will increase gradually on the next months. The decreasing of BCS happened due to the high milk production which was not accompanied with enough feed, therefore the body fat reserves which were deposited on the observed parts decreased. This body fat was used for another energy sources except from feed. Generally The body condition score was 3.500+0.315 for dry off period in Sukajaya.

Judul: Closed Knight’s Tour pada Papan Catur Berbentuk Persegi Panjang dengan Ukuran Maksimal 8 × 8
Abstrak: Closed Knight’s Tour merupakan langkah kuda yang mengunjungi setiap kotak pada papan catur tepat satu kali dengan langkah kuda berawal dan berakhir pada kotak yang sama. Graf yang terbentuk dari closed knight’s tour dinotasikan sebagai graf G(m,n), dengan m adalah banyaknya baris dan n adalah banyaknya kolom. Graf tersebut memuat Hamiltonian cycle. Sebuah graf terhubung G adalah graf bipartite jika dan hanya jika graf tersebut tidak memiliki cycle dengan panjang ganjil. Papan catur yang memenuhi syarat cukup untuk memiliki closed knight’s tour adalah papan catur berukuran 5 × 6, 5 × 8, 6 × 6, 6 × 7, 6 × 8, 7 × 8, dan 8 × 8.
