Judul: Penelitian pendahuluan tentang pembuluh darah san saraf pada kaki belakang kambing ( Capra sp. )
Abstrak: Kambing (Capra sp.) banyak digunakan sebagai bahan praktikum Anatomi di Fakultas Kedokteran Hewan Institut Pertanian Bogor, karena dianggap cukup mewakili golongan ruminansia yang merupakan populasi ternak terbesar di Indonesia. Dalam rangka menunjang pelaksanaan praktikum Anatomi tersebut di atas, maka penelitian ini dilaksanakan untuk melengkapi pustaka mengenai Anatomi kambing. Dalam penelitian ini digunakan satu ekor kambing (Capra sp.) berjenis kelamin betina. digunakan adalah Chloral hidrat 10%, Obat bius yang larutan pengawet Formalin 10% dan 4%, larutan pewarna Arteri dipakai campuran lateks dan cat Vinilex Nippon Paint BS 0-005 Hibisco dengan perbandingan 3: 1. Tehnik bekerja berpedoman pada Buku Penuntun Praktikum Anatomi Veteriner jilid II dan III karangan Soesetiadi (1972).

Judul: Penelitian pendahuluan tentang vaskularis dan intervasi kepala dan leher kambing
Abstrak: Penulisan skripsi ini bertujuan untuk mengetahui tata cara persiapan preparat praktikum, menambah bahan pustaka dan membuat gambaran makro anatomi kepala dan leher kambing (Capra sp.) dengan vaskularisasi dan inervasinya. Kambing berasal dari genus capra, yang berbeda dengan domba dan sapi tetapi secara umum struktur anatominya mudah dibedakan. Terkadang antara kambing dan domba dari varietas tertentu sulit dibedakan. Sampai dewasa ini kebanyakan buku-buku teks anatomi hewan piara yang tersedia, masih menitik beratkan anatomi. kuda sebagai bahan pokok dan anatomi golongan ruminansia, dalam garis besarnya hanya melukiskan anatomi sapi dan dom ba. Jarang atau hampir tidak mempersoalkan anatomi kambing. Adapun buku teks yang sekarang dipakai sebagai pegangan untuk mempelajari anatomi kambing adalah "Anatomy of the Sheep "karangan May (1970), karena dombalah yang di anggap paling menyerupai kambing. Arteri-arteri yang ditemukan untuk vaskularisasi daerah leher dan kepala adalah: Truncus brachiocephalicus, Truncus bicaroticus, A. carotis communis sinistra dan dex tra, A. occipitalis, A. carotis externa, A. lingualis, A. maxillaris, A. temporalis superficialis, A. auricularis caudalis, A. transversa faciei, A. labialis maxillaris dan A. labialis mandibularis.

Judul: The Construction of Greedy SVP LLL Algorithm
Abstrak: A lattice is a set of all integer linear combination of a set of linearly independent vectors in ℝ𝑛���. The independent vectors are called bases of lattice. Any lattice can be generated from many bases, and these bases have the same cardinality. In the lattice, the most fundamental and renowned problem is the Shortest Vector Problem (SVP). SVP is a tracking problem of the shortest nonzero vector in a lattice with equivalent bases. In two dimensions, SVP problem has resolved exactly by Gauss’ algorithm. When the lattice dimension is higher than two, A.K. Lenstra, H.W. Lenstra and L. Lovasz gave a LLL algorithm to compute approximation of nonzero shortest vector in the lattice. Reduced bases solution obtained from LLL algorithm still be an approximation and has polynomial running time of arbitrary dimension which large enough. In 1994, Schnoor and Euchner modified this LLL algorithm as a new variant which later was named deep insertion LLL algorithm. This algorithm is a modified version of the LLL algorithm to the terms of the exchange step to improve the accuracy of output of LLL reduced bases and applying it to the subset sum problem. The purpose of this research are: (1) Reconstruct the LLL algorithm and deep insertion LLL algorithm using a geometric approach. (2) Construct a greedy SVP LLL algorithm. (3) Implement the three algorithms in a symbolic programming language, and evaluate them experimentally. A bases ℬ=[𝐛���1,𝐛���2,…,𝐛���𝑛���] in ℝ𝑚��� is called reduced LLL with parameter 𝛿��� if satisfies: (a) |𝜇���𝑗���𝑖���|≤12, for every integer 𝑖���,𝑗��� with 1≤𝑖���<𝑗���<𝑛���. (b)𝛿���‖𝜋���𝑗���(𝐛���𝑗���)‖2≤‖𝜋���𝑗���(𝐛���𝑗���+1)‖2, for 𝑗���=1,2,…,𝑛���−1,where 𝛿��� is a reduced parameter of real numbers with 14<𝛿���<1. The first requirement is the reduced basis 𝛿��� must “nearly orthogonal” and in its computation case, this requirement can be reached out by using the Gram-Schmidt’s orthogonalization. While the second requirement is called exchange step, or used to called as Lovasz condition. By using both of these requirements, then they establish the LLL algorithm. Then, Schnoor and Euchner modify the LLL algorithm based on the requirements of the exchange step called the deep insertion LLL algorithm, where the exchange step is based on the comparison of the projected vector in orthogonal complement [𝐛���1,𝐛���2,…,𝐛���𝑘���−1]⊥ after j-th reduction. To construct greedy SVP LLL algorithm, the requirements of the exchange step is based on purely by comparing norm of lattice 𝐛���𝑗��� with norm lattice 𝐛���𝑖��� for 𝑖���=1,2,3…,𝑗���−1. The process of insertion reduced vector after the exchange step also has done greedily. Then, we calculate the number of arithmetic operation in greedy SVP LLL algorithm for further analysis. The result of our exprimentation for three algorithms on the certain matrix size shows that the running time of the three algorithms increases propotional to the size of the matrix. The result also shows that by using 𝛿���=34 for the LLL algorithm and the deep insertion LLL algorithm, and the greedy SVP LLL algorithm which is a new variant made by using no parameter of 𝛿���, outperform of the other of two previous algorithm in terms of speed with the same output.
