Judul: Kajian Respon Fisiologis dan Tingkah Laku Stres Ternak Domba di Desa Lingkar Kampus IPB Dramaga Bogor.
Abstrak: Sheep is one of popular ruminants in Indonesia, because sheep is one of source of animal protein, and also easy and convenient to be raised. Problem encountered in the development of rural farm is low productivity. This research aimed to evaluate the physiological response and stress behavior of sheep in the villages around campus IPB Dramaga Bogor at the age and time of difference. This research used 16 lambs from each of I0 (<1 year old) and I1 (1-1.5 years old) and observed for about two months. Parameters of physiological response that had been observed were respiration rate, heart rate, and rectal temperature. The parameters of behaviors that had been observed were resting, agonistic, vocalization, locomotive, and ingestive behaviours. Physiological response and behaviours data were analized by using analysis of variance (ANOVA). The research results showed that the heart rate and rectal temperature was affected by age. Sheep in age I0 had higher heart rate and rectal temperature (p<0.05) compared in age I1. Sheep behaviors were not affected by the treatment, namely frequency on every treatment was the same. In general, frequency of resting and ingestive were higher than the frequency of other behaviors. However, in general it was concluded that physiological response and behavior of sheep farmed in the village around campus Dramaga IPB Bogor were still in normal conditions, therefore the sheep in this area would be ready to be more developed.

Judul: Respon fisiologis domba garut yang dipelihara secara semi intensif dengan perlakuan pencukuran di peternakan PT Indocement
Abstrak: The study was conducted to identify physiological response of garut sheep in different treatments (shearing and not shearing) and sex (male and female) in semi intensive system. The experiment was carried out at the PT Indocement Farm in Citereup district of Bogor regency, West Java. Design of this experiment was completely randomized design factorial with factor A was shearing, and factor B was sex. The parameters observed included body temperature, heartbeat, respiration rate and blood profile. The result showed that shearing significantly (P<0,01) effect on body temperature in the morning. Body temperature of shearing sheep (37.97±0.28 0C) was lower than not shearing (38.47±0.310C). In the afternoon showed that shearing significant (P<0.05) effect on body temperature. Body temperature of shearing sheep (38.45±0.20 0C) was lower than not shearing (38.70±0.25 0C). Heartbeat of male (86.72±6.47 rate/min) was significant higher than female (81.24±4.12 rate/min) in the evening. Respiration rate of male (24.08±2.78 rate/min) was significantly lower than female (28.16±2.20 rate/min) in the morning. For shearing sheep was lower than not shearing in the morning and afternoon. In the evening both male and female sheep that are not shearing was not significant, but significant with respiration of male sheared and female sheared. Stress indicated in male sheep and proved from neutrophils/lymphocytes ratio (0.88±0.36). Conclusion of this experiment showed that shearing, sex and time effected to the physiological response.

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.
