Judul: Electrocardiogram of Pigs (Sus scrofa domestica) as Animal Model Candidate of Artificial Myocardial Infarction
Abstrak: Penelitian ini bertujuan mengetahui perubahan aktivitas listrik jantung akibat infark miokardium pada hewan model babi (Sus scrofa domestica) menggunakan elektrokardiografi (EKG). Pengambilan data dilakukan pada tiga ekor babi jantan dengan umur 4-5 bulan. Perekaman data EKG dilakukan sebelum dan setelah prosedur operasi pembuatan infark miokardium pada babi. Parameter yang diamati adalah durasi P, amplitudo P, interval PR, interval QRS, amplitudo R, amplitudo T, interval QT, segmen ST, dan frekuensi denyut jantung yang direkam pada sadapan II. Data yang diperoleh dianalisis menggunakan uji paired sample T test dan dinyatakan dalam nilai rata-rata serta standar deviasi. Hasil rekaman EKG menunjukkan adanya perbedaan nyata pada parameter interval PR, gelombang T, interval QT, segmen ST, dan frekuensi denyut jantung. Hal ini menunjukkan bahwa kondisi infark miokardium mempengaruhi konduksi listrik atau aktivitas kelistrikan jantung.

Judul: Erythrogram Profile of Pig (Sus scrofa domestica) Before and After the Myocardial Infarction Condition with total occlusion of the circumflex artery
Abstrak: Penelitian ini bertujuan mengetahui gambaran eritrogram babi (Sus scrofa domestica) sebagai hewan model pada keadaan sebelum dan sesaat setelah kondisi infark miokard dengan oklusi total arteri sirkumfleks. Babi dengan jumlah 9 ekor dilakukan aklimatisasi. Hewan dipuasakan minimal 12 jam sebelum dilakukan operasi. Babi dianastesi menggunakan ketamin 10% (dosis 0,5 mg/kg) dan xylazine 2% (1 mg/kg). Operasi pembuatan infark miokard dilakukan oklusi total dengan cara ligasi pada cabang proksimal dari arteri sirkumfleks dengan jahitan non- absorbable polypropylene 5.0 monofilament. Hambatan aliran darah dilakukan dengan rentang waktu 2 - 3 jam. Pengambilan darah dilakukan sebelum dan sesaat setelah terjadinya infark jantung dengan masing - masing pengambilan sebanyak ± 3 ml dilakukan melalui vena jugularis kemudian dimasukkan ke dalam vacutainer yang berisi antikoagulan K3 Ethylenediaminetetraacetic acid (K3EDTA). Sampel darah dilakukan pemeriksaan eritrogram menggunakan hematology analyzer terhadap jumlah eritrosit, kadar hemoglobin, nilai hematokrit, dan indeks eritrosit (MCV, MCH, dan MCHC). Hasil penelitian menunjukkan rata-rata eritrosit, hemoglobin, MCV, MCH, dan MCHC sebelum dan setelah infark miokardium (2 – 3 jam setelah oklusi total arteri sirkumfleks) masih berada pada nilai kisaran normal, sedangkan rata-rata hematokrit berada dibawah kisaran nilai normal. Satu ekor babi ditemukan sebelum dan setelah infark memiliki hasil yang merujuk pada terjadinya anemia mikrositik hipokromik., The objective of this research was to determine the profile of the erythrogram of pigs (Sus scrofa domestica) as animal models in the conditions before and shortly after the myocardial infarction with total occlusion of the circumflex artery. A total of 9 pigs were acclimatized. Pigs were fasted for at least 12 hours before surgery. Pigs were anasthetized using 10% ketamin (0.5 mg/kg dose) and 2% xylazine (1 mg/kg). Myocardial infarction surgery was performed in total occlusion by ligation of the proximal branch of the circumflex artery with a non-absorbable polypropylene 5.0 monofilament suture. Blood flow resistance occurs with a period of 2 - 3 hours. ± 3 ml of blood was drawn through the jugular vein and then put into a vacutainer containing the anticoagulant K3 Ethylenediaminetetraacetic acid (K3EDTA). The blood sample was then examined for erythrogram using a hematology analyzer on the number of erythrocytes, hemoglobin level, hematocrit value, and erythrocyte index (MCV, MCH, and MCHC). The mean values of erythrocyte, hemoglobin, MCV, MCH, and MCHC parameters before and after myocardial infarction (2 – 3 hours after the total occlusion of the circumflex artery) were at normal values. In contrast to the average hematocrit which is below the normal value. One of the pig show results that refer to the occurrence of microcytic hypochromic anemia.

Judul: Query Expansion based on Bilingual Dictionary Using Conditional Probability
Abstrak: Query expansion is a technique that can be used to bridge vocabulary gaps between queries and documents in the collection. With query expansion, user will be helped to formulate queries well so that user will optimize the search result. In this study, the expansion term was resulted from the translation of bilingual dictionary. Subsequently, several terms of expansion were elected based on the closeness of its relationship with the original query. This research showed that conditional probability can be used to select expansion term in bilingual translation method query expansion. The result of 1000 documents was more than 97% relevan document can be retrieved by this system. The more expansion term used, the larger number relevan document was retrieved.
