Judul: Evaluasi Status Fisiologi Pengaruh Anestesi Per Injeksi Dan Per Inhalasi Dalam Rangka Operasi Penanaman Implan Tulang Sintetis Pada Domba (Ovies aries)
Abstrak: This study aimed to observe the effect of injection and inhalation anasthetical method, such as, the value of oxygen saturation, heart frequency, respiratory frequency and body temperature in sheeps model during the synthetical bone implant surgery. Injection and inhalation anaesthetical methods were used in this experiment. The local sheep (Ovies aries), as an animal model, was used and prepared indoor for experiment adaptation. The method of this research was divided into two methods: 1) The first treatment group P1 was consisted of two sheeps and they were anaesthetical (per injection) using xylazine hydrochloride 2% with a dose of sheep 0.1 – 0.2 mg/kg by intramuscular (IM) and 0.1 mg/kg by intravena (IV), 2) The second treatment group P2 was consisted of two sheeps and they were anaesthetical (per inhalation) using isoflurane 1.5% - 3% with a fresh-gas flow rate 25 ml/kg. The results showed that there are some differential values, especially the injection anaesthetical route and inhalation anaesthetical route oxygen saturation, heart frequency, respiratory frequency and body temperature. It can be concluded that isoflurane as an inhalation anaesthetical route is better than xylazine as an injection anaesthetical route.

Judul: Profil Elektrokardiogram pada Domba Lokal (Ovis aries) Setelah Penanaman Implan Semen Tulang Hidroksiapatit-Kitosan dan Hidroksiapatit-Trikalsium Fosfat pada Tulang Tibia
Abstrak: This study was carried out to evaluate the electrophysiological cardiac activity (ECG) of local sheep following tibia bones implantation using bone cement hydroxyapatite-chitosan and hydroxyapatite-tricalcium phosphate implant. Four lokal sheep (2 males and 2 females) aged between 1.5-2 years old and body weight of 19-20 kg were used in present experiment. The ECG examination was done in conscious with standing position. Some parameters were evaluated such as, amplitude and duration of P wave, QRS complex, PR interval and ST segment. The result showed that P wave amplitude and duration number were not significantly different (P>0.05) compared to normal sheep’s standard scores which mean both cement implants did not influence atrium activity. QRS complex amplitude and durations were significantly different (P<0.05) with normal sheep’s standard scores and resembled to both bone cement implants influence ventricle activity. PR interval and ST segment durations were significantly different with normal sheep’s standard scores. Overall, ventricle activity was disturbed post treated using bone cement implant. This disturbance is due to there was ischemic ventricular muscle.

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
