Judul: The Ultrasound Imaging Result of Spleen, Stomach, and Prostate in Piglet (Sus scrofa domestica).
Abstrak: Penelitian ini bertujuan untuk mendeskripsikan pencitraan ultrasonografi organ limpa, lambung, dan prostat pada anak babi (Sus scrofa domestica), sehingga dapat menjadi data acuan untuk posisi organ, struktur organ, ekhogenitas, dan ukuran organ normal. Ultrasonografi dilakukan pada enam ekor anak babi jantan umur 1 bulan 1 hari dengan bobot badan 4 - 8 kg. Pemeriksaan fisik dilakukan untuk memastikan anak babi dalam kondisi sehat. Ultrasonografi organ limpa, lambung, dan prostat diamati pada posisi dorsal-recumbency. Pemeriksaan ultrasonografi menggunakan Chison EBit 60, transduser tipe linear frekuensi 9 MHz dengan posisi transversal dan sagital dan gain sekitar 55 - 80. Hasil ultrasonografi limpa, terdapat bentuk kepala limpa yang bervariasi pada setiap individunya. Hasil ultrasonografi lambung dapat melihat lapisan lambung dengan jelas dan kesamaan posisi, struktur, ekhogenitas, dan ukuran lambung. Hasil ultrasonografi prostat didapatkan rata-rata panjang prostat dari ke – 6 anak babi 2.68 ± 0.45 cm dan rata- rata lebar prostat dari ke – 6 anak babi 1.69 ± 0.35 cm. Bentuk prostat pada hasil penelitian yang didapat bervariasi, namun semua prostat tetap berbentuk melengkung mengikuti dinding uretra setiap individunya. Hasil penelitian ini dapat dijadikan acuan data normal posisi organ, struktur organ, dan ekhogenitas organ limpa, lambung, dan prostat pada anak babi (Sus scrofa domestica)., This study aimed to describe the ultrasound imaging result of spleen, stomach, and prostate in piglet (Sus scrofa domestica), therefore the data can be used to be the reference of position, structure, echogenicity, and size of normal organ. An ultrasound performed in six male piglets in the age of 1 month and 1 day with body weight 4 - 8 kg. Physical examination was done to make sure the piglets in healthy condition. Ultrasound of spleen, stomach, and prostate observed in dorsal-recumbency position. Ultrasound was performed using Chison EBit 60, linear transducer with 9 MHz frequency at the transversal and sagittal position and gain 55 - 80. Result of the spleen ultrasound shows the head of spleen with variant form in every individual. Result of the stomach ultrasound shows layers of stomach clearly and from the six piglets they having the same position, structure, echogenicity, and size. Result of the prostate ultrasound with average length from the six piglets are 2.68 ± 0.45 cm and average width from the six piglets are 1.69 ± 0.35 cm. Form of prostate shows variant from each individual, however every prostate still had similarity in curve, following the wall of urethra. The results of this research can be a normal data for position, structure, and echogenicity of spleen, stomach, and prostate in piglet (Sus scrofa domestica).

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: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
