Judul: Gambaran darah ikan mas
Abstrak: Di Indonesia penelitian mengenai darah ikan mas masih jarang dilakukan, juga dari ikan-ikan lainnya. Sedangkan gambaran darah sangat perlu misalnya untuk membantu mendiagnosa suatu penyakit ikan. Dengan demikian tujuan penelitian ini adalah untuk mengetahui gambaran darah ikan mas dari ketiga kelompok ukuran panjang. Kelompok 1 berukuran 15 17 cm, kelompok 2 berukuran 23 -25 cm dan kelompok 3 berukuran 29 33 cm, dalam keadaan normal. Dalam penelitian ini tidak dilakukan pembiusan terhadap ikan mas. Ikan mas dibungkus dengan kain basah, kemudian darah diambil dari arteri caudalis dengan menggunakan alat suntik (2,5 cc). Darah ditampung pada gelas arloji yang dilapisi parafin, untuk selanjutnya dilakukan pengukuran kadar hematokrit, hemoglobin yang berdasarkan metoda Hesser (1960). Sedang penghitungan jumlah eritrosit, lekosit dan trombosit menggunakan metoda Pavlovskii (1964). ...

Judul: Morfologi darah ikan mas (Cyprinus carpio), Nila merah (Oreochromis sp.), dan lele dumbo (Clarias gariepinus) dari Sukabumi
Abstrak: Penelitian ini bertujuan untuk mengetahui perbedaan-perbedaan morfologi darah pada ikan mas (Cyprinus carpio), nila merah (Oreochromis sp.) dan lele dumbo (Clarias gariepinus) dari Sukabumi. Penelitian dilakukan di Laboratorium Parasit Fakultas Perikanan IPB di Dramaga dan Balai Budidaya Air Tawar (BBAT) Sukabumi dari tanggal 30 Agustus 1989 sampai dengan 30 Januari 1990. Penelitian ini meliputi pengambilan contoh ikan dari Sukabumi dan pembuatan preparat ulas darah serta pemeriksaan dibawah mikroskop di Laboratorium Parasit. Pengambilan contoh ikan dilakukan tiap bulan sekali sebanyak 30-100 ekor dan 30 ekor untuk pembuatan preparat ulas darah. Pemeriksaan dilakukan terhadap ukuran dan bentuk sel darah, letak inti, afinitas sel terhadap zat warna serta identifikasi parasit. Dari hasil penelitian diketahui jenis sel darah yang terdapat pada ketiga ikan tersebut yaitu proeritrosit, eritrosit, trombosit, limfosit, monosit, neutrofil, dan blast cell. Pengelompokan sel-sel tersebut berdasarkan persamaan morfologi dengan sel darah mamalia. Sel-sel tersebut mempunyai ukuran yang berbeda-beda antara ketiga ikan tersebut, sedangkan untuk bentuk dan kemampuan setiap sel dalam menyerap zat warna antara ketiga ikan tersebut sebagian besar tidak menunjukkan adanya perbedaan kecuali pada sel eritrosit. ...

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.
