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: 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: 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.
