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: Respon Fisiologis dan Tingkah Laku Domba Garut dengan Pakan Limbah Tauge atau Kangkung Kering sebagai Pengganti Rumput
Abstrak: Garut sheep is commonly reared in West Java and usually fed with grass as the main feed and energy source. However, this grass has low quality and seasonally available, therefore should be an alternative feed such as mung bean sprout waste and dried kangkung. This research aimed to study sheep physiology and behavior as a response to diet and environment. This research used nine garut sheep (I0) with three treatments and replicates. The treatments were P0 (50% grass+50% consentrate), P1 (50% mung bean sprout waste+50% concentrate) and P2 (50% dried kangkung+50% concentrate). Physiological response data were analyzed by analysis of variance (ANOVA) and tested by Tukey post test method, while behavior frequency data were analyzed by Kruskal-Wallis test. Result showed that diet treatment did not affect (P>0.05) the heart and respiration rate, but significantly affected (P<0.05) on rectal temperature. All behaviors parameters were not significantly different (P>0.05) except for resting, grooming, licking strange object, and locomotion were higher in P1 than P0 and P2.

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.
