Judul: Infeksi Cacing pada Monyet Ekor Panjang (M. fascicularis) di Gunung Kapur Kecamatan Ciampea Kabupaten Bogor.
Abstrak: Konflik manusia-hewan yang terjadi antara masyarakat dan monyet ekor panjang di wilayah sekitar Gunung Kapur, Kecamatan Ciampea, Kabupaten Bogor berpotensi menyebarkan penyakit zoonosis termasuk kecacingan. Dengan demikian dilakukan Penelitian ini untuk mengetahui gambaran infeksi cacing pada monyet tersebut. Penelitian ini bersifat deskriptif dengan fokus pengamatan pada telur cacing yang terdapat pada sampel tinja monyet. Hasil pengamatan kualitatif menunjukkan terdapat tiga jenis telur cacing yang menginfeksi monyet yaitu telur cacing tipe Ascarid, Strongylid dan Schistosoma. Gambaran infeksi positif yang tinggi yaitu 76.67% terdiri atas infeksi tunggal (69.57%) dan infeksi campuran (30.43%). Derajat infeksi oleh cacing Ascarid dan Strongylid termasuk infeksi ringan. Ketiga cacing yang ditemukan dalam Penelitian ini diduga berpotensi zoonosis.

Judul: Infeksi Cacing Nematoda pada Saluran Pencernaan Monyet Ekor Panjang (Macaca fascicularis) di Matraman, Jakarta dan Taman Wisata Alam Telaga Warna, Bogor
Abstrak: Gastrointestinal nematode are common parasite found in warm-blooded animals, including Macaca fascicularis. Infection transmission of parasitic nematode in M. fascicularis can occur intraspesies and interspesies. The existence of macaque in homesite at Matraman, Jakarta allowing the parasite transmission from monkeys to humans, or vice versa. Free-living macaque’s in Nature Recreational Park of Telaga Warna are used as a benchmark to determine the prevalence of gastrointestinal nematode infection. Identification results of nematode eggs and larvae in monkeys on Matraman showed Strongyloides 66.67%, Trichostrongylus 58.33% Oesophagostomum 50% and hookworm 45.83%. Identification of nematode eggs and larvae in monkeys at Telaga Warna showed Strongyloides 14.29%, Oesophagostomum 19.05%, Trichostrongylus 19.05%, hookworm 14.29%, Trichuris 14.29% and Ascaris 9.52%. Total prevalence of monkeys in Matraman was at 80.95% and in Telaga Warna 52, 38%. Infection prevalence of parasitic nematode in M.fascicularis seattlement area are bigger than the natural habitat.

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.
