Judul: Morfometri Struktur Internal Organ Ginjal, Aorta Abdominalis, dan Kantung kemih pada Babi (Sus scrofa domestica)
Abstrak: This study aimed to know the internal structure morphometry of the kidney, abdominal aorta, and bladder on pig (Sus scrofa domestica), therefore the data can be used to be the reference of position, form, echogenicity, and size of the organ. An ultrasound performed on six pigs, three males and three females with body weight 25.0-31.0 kg. Physical examination and blood analysis were done to make sure the pig in a healthy condition. Ultrasound of the kidney and abdominal aorta observed in lateral recumbency position, whereas the bladder were observed on the dorsal recumbency position. Ultrasound was performed using a 5.5 MHz convex transducer at the transversal and sagittal position. Results of the right kidney was 7.02±0.40 cm in length, 2.74±0.08 cm in height, and 4.51±0.27 cm in width, for the left kidney was 6.64±0.72 cm in length, 2.59±0.09 cm in height, and 3.44±0.32 cm in width. Diameter results of the abdominal aorta was 1.00±0.14 cm. The maximum length of the kidneys and the diameter of the abdominal aorta were compared to get the ratio value. The ratio value results was 1:7.02 for the right kidney and 1:6.64 for the left kidney. Wall thickness results of bladder in sagittal view was 0.26±0.12 cm and in transversal view was 0.25±0.10 cm. The results of this research can be a normal data for the size of the kidneys, abdominal aorta, and bladder on a pig.

Judul: The Ultrasound Imaging of Bladder,  Kidney, and Liver in Piglets (Sus scrofa domestica)
Abstrak: Penelitian ini bertujuan untuk mengetahui gambaran USG hati, ginjal dan kandung kemih pada anak babi (Sus scrofa domestica), sehingga data tersebut dapat digunakan sebagai acuan untuk pemeriksaan posisi, ekogenisitas, dan ukuran. Ultrasonografi dilakukan pada enam ekor anak babi jantan berumur 1 bulan 1 hari. Pemeriksaan klinis dilakukan untuk memastikan anak babi dalam keadaan sehat. USG hati dan kandung kemih diamati pada posisi dorsal recumbency, sedangkan ginjal diamati pada posisi lateral-recumbency. Ultrasonografi dilakukan menggunakan Chison EBit 60, transduser linier dengan frekuensi 9 MHz pada posisi sagital dan gain 50 - 80. Ekogenisitas hati cenderung hiperekoik, ginjal hiperekoik, dan kandung kemih hipoekoik karena penggunaan gain yang tidak tepat. Pencitraan kandung kemih menunjukkan perubahan ukuran dinding dan ekogenisitas. Panjang rata-rata ginjal kanan 4,73±0,50 cm dan ginjal kiri 4,08±0,26 cm. Ketebalan dinding kandung kemih adalah 1,3 ± 0,31 mm. Pengukuran panjang ginjal dan ketebalan dinding kandung kemih yang diperoleh menunjukkan hasil yang hampir seragam sehingga pada penelitian ini diketahui posisi, ekogenisitas, dan ukuran organ normal, This study aims to determine ultrasound imaging of the liver, kidneys and bladder in piglets (Sus scrofa domestica), therefore the data can be used as reference for examination position, echogenicity, and size of the organs. Ultrasound was performed on six male piglets aged 1 month and 1 day. Clinical examination was conducted to ensure that the piglets are in good health. Ultrasound of the liver and bladder was observed in dorsal-recumbency position, while the kidneys were observed in lateral-recumbency positions. Ultrasound was performed using Chison EBit 60, linear transducer with 9 MHz frequency at the sagittal position and gain 50 - 80. The echogenicity of the liver tends to be hyperechoic, the kidneys are hyperechoic, and the bladder is hypoechoic due to improper use of gain. Bladder imaging showed changes in wall size and echogenicity. The average length of the right kidney was 4.73±0.50 cm and the left kidney was 4.08±0.26 cm. The bladder wall thickness is 1.3±0.31 mm. Measurements of kidney length and bladder wall thickness obtained showed almost uniform results so that in this study the data on the position, ecogenicity, and size of normal organs were known.

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.
