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: Description of Blood Pressure and Oxygen Saturation Pre and Post Induction of Acute Myocardial Infarction in Pigs (Sus scrofa domestica)
Abstrak: Infark miokardium merupakan penyakit kardiovaskular dengan tingkat kematian yang cukup tinggi. Pemeriksaan tekanan darah dan saturasi oksigen (SpO₂) pada pasien dapat dilakukan untuk mendeteksi masalah sirkulasi pada tubuh. Penelitian ini bertujuan mengetahui gambaran nilai tekanan darah dan SpO₂ pada babi pre dan post induksi infark miokardium akut. Babi diinduksi infark miokardium akut dengan ligasi di proksimal arteri circumflex coronary. Tekanan darah diperiksa menggunakan non-invasive blood pressure cuff yang disambungkan dengan veterinary blood pressure monitor dan SpO₂ diperiksa menggunakan SpO₂ adapter cable yang disambungkan dengan patient monitor. Data yang diperoleh dari penelitian ini dianalisis secara deskriptif terhadap perubahan SpO₂ dan tekanan darah ±15 menit pre dan post induksi infark miokardium akut. Hasil penelitian menunjukkan penurunan rata-rata nilai tekanan darah sistolik dari 93,4 ± 11,08 mmHg menjadi 68,4 ± 13,79 mmHg. Rata-rata nilai tekanan darah diastolik menurun dari 54,6 ± 16,1 mmHg menjadi 37,6 ± 15,79 mmHg. Rata-rata nilai SpO₂ menunjukkan kenaikan dari 94.6 ± 6,23% menjadi 96,2 ± 2,95%. Nilai tekanan darah berada di bawah rentang normal pre induksi dan semakin menurun post induksi. Nilai SpO₂ mengalami perubahan yang bervariasi pada setiap individu dengan rata-rata mengalami kenaikan., Myocardial infarction is a cardiovascular disease with high mortality rate. Examination of blood pressure and oxygen saturation (SpO₂) in patients can be done to detect circulation problems in the body. This study aims to describe the value of blood pressure and SpO₂ in pigs pre and post induction of acute myocardial infarction. Pigs induced with acute myocardial infarction by ligation of the proximal branch of the circumflex coronary artery. Blood pressure was checked using a non-invasive blood pressure cuff connected to a veterinary blood pressure monitor and SpO₂ was checked using an SpO₂ adapter cable connected to the patient monitor. The data obtained from this study were analyzed descriptively on changes in SpO₂ and blood pressure ±15 minutes pre and post induction of acute myocardial infarction. The results showed a decrease in the average value of systolic blood pressure from 93,4 ± 11,08 mmHg to 68,4 ± 13,79 mmHg. The average value of diastolic blood pressure decreased from 54,6 ± 16,1 mmHg to 37,6 ± 15,79 mmHg. The average SpO₂ value showed an increase from 94,6 ± 6,23% to 96,2 ± 2,95%. Blood pressure values were below the normal range pre induction and decreased post induction. The value of SpO₂ varies in each individual with an increased average.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
