Judul: Karakteristik struktur skelet kaki biawak air (Varanus salvator)
Abstrak: This study was aimed to observe the marphological of appendicular skeleton of Varanus salvator, associated with the function and behavior. Anatomy of appendicular skeleton of V. salvator was observed and measured of length of bones and joints. The bones and their parts of appendicular skeleton named base on Nomina Anatomica Veterinaria 2012 and Atlas of Komodo Dragon. On the forelimbs, os scapula has a convex shape, and has a broad joint with the os humerus. In the proximal part of the os humerus was found crista pectoralis, and the distal part of the bone is widened laterally. Ossa radius et ulna has spatium interosseum antebrachii along both of the bones. The hindlimbs consists of the os coxae has a concave shaped, os femoris which has three ossa articulatio genus on femorotibiofibularis joints, ossa et tibia fibula has spatium interosseum cruris along both of the bones. Soles area of the forelimbs and hindlimbs composed of ossa carpi/tarsi, ossa metacarpalia/metatarsalia and ossa phalanges manus/pedis which has compact structure and distinctive. This supports the ability to climb trees and gripping prey. The skeletal structure of the limb causes a high flexibility in the movement of the forelimbs and hindlimbs skeleton.

Judul: Studi Karakteristik Anatomi Skelet Kepala Biawak Air (Varanus salvator)
Abstrak: The study was aimed to observe the characteristics of cranial skeleton of Varanus salvator, compared to its function and behavior. This study was conducted by observing speciment of water monitor lizards cranial skeleton and the observation was compared with related litelatures. The results showed that the head of water monitor lizard had 12 cm in length, 7 cm in width and 5 cm in height. Water monitor lizard have a marginal pleurodont teeth that grows on the side of the jaw with one tooth replacement on each marginal tooth. Relationships between bone of the head very closely and a few bones like os lacrimale, os temporale and os postorbitale grows attached to each other with the surrounding bones. Pars splanchnocranii thrives and elongated, and os supraorbitale found in this area. Columella cranii found in the pars neurocranii and os squadratum well developed in this area. Canalis interincisivum found on the hard palate that connects the oral cavity and the nasal cavity. This channel is functionally compared to the olfactory system because it associated with organon jacobson.

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.
