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: Evaluasi Gambaran Klinis Persembuhan Tulang Implan Hidroksiapatit Kitosan (Ha-Kitosan) dengan Hidroksiapatit Trikalsium Fosfat (HA-TKF) pada Domba Lokal (Ovis aries) sebagai Hewan Model untuk Manusia
Abstrak: The aim of this study was to evaluate clinical view between bone healing process of implanted hydroxyapatite-chitosan (HA-Chitosan) with hydroxyapatite-tricalcium phosphate (HA-TCP) in local sheep. Six healthy sheep were divided into two groups. Three sheep received HA-chitosan implant, while the others received HA-TCP implant. Observations were carried out by clinical examination of pre-surgery and post-surgery until sheep were harvested. The result showed that implantation of HA-Chitosan and HA-TCP did not interfere the physiological of body temperature, heart rate and respiratory rate of sheep, also did not prolong the inflammation and did not generate an immune response. Both HA-chitosan and HA-TKF implant were well tolerated by the body and did not interfere the physiological body but the implant of HA-Chitosan and HA-TKF did not accelerate bone healing.

Judul: Heisenberg Uncertainty of Double SlitSystem Based on Budiyono-Rohrlich Quantum Statistics Model
Abstrak: Interpretasi kuantum dikembangkan untuk memaknai secara fisis dengan jelas bagaimana suatu dinamika pada sistem mikroskopis yang dijelaskan dengan teori-teori kuantum, seperti interpretasi Copenhagen yang mendeskripsikan sistem kuantum sebagai suatu keadaan yang dideskripsikan dengan fungsi gelombang yang berisikan bagaimana peluang keadaan suatu sistem. Interpretasi kuantum juga bisa dibawa dari suatu sistem klasik seperti pada model statistika-kuantum Budiyono-Rohrlich yang menjelaskan bagaimana dinamika kuantum berhubungan dengan sistem klasik dengan penerapan statistika pada model Hamiltonian sistem. Fungsi distribusi dapat mendeskripsikan bagaimana suatu sistem terdistribusi pada suatu ruang pada pandangan klasik namun untuk sistem kuantum fungsi distribusi adalah peluang dari sistem tersebut. Sistem klasik dan kuantum juga dipisahkan berdasarkan pada ketidakpastian Heisenberg tentang suatu pengukuran yang tidak bisa secara sekaligus dilakukan bersamaan. Model statistika-kuantum Budiyono-Rohrlich membawa suatu sistem klasik menjadi sistem kuantum dengan dua aksioma yaitu hukum kekekalan energi rata rata dan konservasi rapat probabilitas. Sistem klasik yang didefinisikan akan diatur dengan menambahkan dua variable matematis berupa ontic extensions dan epistemic restrictions dimana kedua variabel ini yang akan menghubungkan bagaimana sistem klasik bisa diubah menjadi sebuah sistem kuantum. Dua variabel matematis tadi membuat sebuah sistem bisa diperlihatkan ketidakpastiannya lewat perhitungan simpangan rata-rata dan hasilnya akan selalu memenuhi ketidakpastian Heisenberg
