Judul: Tingkah Laku dan Rekam Jejak Kambing Kacang dengan Warna Kulit Berbeda pada Penggembalaan Semi Intensif
Abstrak: Difference in coat color affects difference in kacang goat behavior during grazing time. Objective of this research was to analyze effect of coat color on behavior and movement of kacang goat during grazing time. This research used 9 females and 3 males of kacang goat. Behavior observed by one zero sampling method and analyzed using t-Test at level 5%. Result indicated that ingestive and browsing of brown goat (30.91 ± 2.87%; 8.75 ± 3.10%) higher (P<0.05) than black goat (28.57 ± 2.69%; 6.07 ± 4.78%), while black goat showed more locomotion (33.26 ± 4.50%) than brown goat (29.70 ± 4.63%). Grazing, panting, and resting behaviors, and distance traveled of black goat (22.56 ± 2.63%; 4.48 ± 4.02%; 2.34 ± 2.97%; 483.48 ± 133.16 m) were not different with brown goat (22.16 ± 2.90%; 4.59 ± 3.71%; 2.64 ± 1.52%; 392.29 ± 81.19 m). Result also indicated that goat showed more grazing than browsing with high preference in young grass than old grass, legume, and weed.

Judul: Perbandingan Distribusi Otot Kambing Kacang dan Peranakan Etawah pada Bobot Lepas
Abstrak: A total of 43 goats which consist of 27 kacang goats and 16 peranakan etawah goatswas used to evaluate the comparison of muscle distribution between kacang goat and PE goat slaughtered over the weight 10 Kg. The data of body components was analyzed using Analysis of Variance (ANOVA) while muscle of distribution and other body components were analyzed using Analysis of Covariance (ANCOVA) with slaughter weight, half carcass weight as a covariable. The result showed that groups of muscles and body components among these breeds were no significantly different (P>0.05). There were no significantly differences among breeds in muscles of groups except the percentages of muscles of groups 3 and the muscles of groups 5. There were no significantly differences among breeds in body components except inter muscle fat weight, subcutan fat weight, inter muscle fat percentage, subcutan fat percentage, and kidney fat percentage. In general, the major muscles groups percentage (groups 1+3+5) in kacang goat is 60.35% and 60.71% for peranakan etawah goat.

Judul: Pemanasan Sekunder Reaksi Fusi Plasma dengan Menggunakan Radio Frequency
Abstrak: Plasma merupakan bentuk ke-empat dari materi setelah padat, cair dan gas yang terbentuk dari proses ionisasi gas. Plasma dapat digunakan dalam reaksi fusi, yaitu reaksi penggabungan dua inti atom ringan menjadi inti atom yang lebih berat sambil melepaskan energi. Untuk mendapatkan energi dari reaksi fusi, inti yang akan direaksikan harus dipanaskan pada temperatur yang sangat ekstrem tingginya. Salah satu cara agar dapat mencapai kondisi ini adalah memberikan pemanasan tambahan atau pemanasan sekunder kepada plasma dalam reaksi fusi tersebut. Nilai daya serap rata-rata ion Deuterium yang sesuai dengan selang nilai daya dari data ITER adalah daya yang menggunakan frekuensi 50 MHz sampai dengan 60 MHz. Dengan menggunakan frekuensi 60 Hz diperoleh nilai daya rata-rata yang diserap sebesar 1,235.10-12 W.
