Judul: Profile of Leukocytes in Pig (Sus scrofa domestica)  Before and After Heart Infarct Surgery
Abstrak: Babi merupakan spesies paling tepat dalam penelitian kardiovaskular, salah satunya infark miokard. Penelitian ini bertujuan memperoleh data jumlah leukosit pada babi domestik (Sus scrofa domestica) sebelum dan sesudah operasi pembuatan infark jantung. Sebanyak enam ekor babi umur empat bulan di Rumah Sakit Hewan Pendidikan, Institut Pertanian Bogor diambil sampel darahnya melalui vena jugularis, kemudian dimasukkan ke dalam tabung vakum yang berisi antikoagulan (K3EDTA) untuk selanjutnya diuji menggunakan hematology analyzer. Data dianalisis secara deskriptif. Hasil penelitian dari 6 sampel yang dianalisis rata-rata jumlah leukosit sebelum dan sesudah operasi pembuatan infark jantung yaitu 16,33 ± 3,62 x 103/μL dan 16,97 ± 4,59 x 103/μL. Peningkatan leukosit dalam darah tidak dapat dijadikan prediktor independen untuk mendiagnosa kejadian infark jantung. Hal ini dikarenakan banyak kejadian yang dapat memicu peningkatan jumlah leukosit dalam darah seperti adanya inflamasi pada saat operasi pembuatan infark jantung.

Judul: Physiological Parameters of Pig (Sus scrofa domestica) Post-Induced Cardiac Infarction with Total Occlusion in Circumflex Artery
Abstrak: Penyakit kardiovaskular adalah penyebab utama kematian di dunia. Sistem kardiovaskular babi dapat digunakan dalam penelitian infark miokardium karena memiliki kemiripan anatomi dan fisiologi dengan manusia. Pemeriksaan parameter fisiologis selama pembedahan merupakan cara cepat dan efisien untuk memantau kondisi pasien, mengidentifikasi masalah, dan mengevaluasi respons pasien terhadap intervensi bedah. Penelitian ini bertujuan mengetahui parameter fisiologis terkait nilai frekuensi napas, frekuensi jantung, dan suhu tubuh 15 menit sebelum dan sesudah induksi oklusi total arteri circumflexa dengan cara ligasi pada babi. Babi yang digunakan berjumlah lima ekor dengan jenis kelamin empat jantan satu betina bobot 51–55 kg. Frekuensi napas dan jantung dipantau dari patient monitor serta suhu tubuh diukur dari termometer digital. Data yang diperoleh diolah secara deskriptif. Frekuensi napas dan frekuensi jantung 15 menit pascainduksi infark miokardium menunjukkan rata-rata terjadinya penurunan tetapi masih berada dalam rentang nilai normal, sedangkan suhu tubuh menunjukkan hasil lebih rendah dari rentang nilai normal meskipun terjadi peningkatan. Hal ini diduga disebabkan perubahan fisiologis, aktivitas saraf, dan hormon., Cardiovascular disease is the leading cause of death in the world. Swine cardiovascular system can be used in the study of myocardial infarction because it has anatomical and physiological similarities to humans. Physiological parameters examination during surgery is a quick and efficient way to monitor the patient's condition, identifying problems, and evaluate the patient's response to surgical intervention. This study aims to determine the physiological parameters related to the value of respiratory rate, heart rate, and body temperature 15 minutes before and before induction of total occlusion of the circumflex artery by ligation in pigs. The number of pigs used were five with the sex of four males and one female weighing 51–55 kg. Respiratory and heart rates were monitored from the patient monitor and body temperature was measured from digital thermometer. Obtained data were processed descriptively. The respiratory and heart rate 15 minutes after the induction of myocardial infarction showed an average decrease within the normal range, while body temperature showed a lower result than the normal value range despite an increase. This has been thought due to physiological changes, neural activity, and hormones.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
