Judul: Tuberkulosis pada Monyet Ekor Panjang (Macaca fascicularis) di Provinsi DKI Jakarta
Abstrak: Monyet ekor panjang merupakan primata omnivora yang banyak dipelihara dan diperdagangkan di Indonesia. Satwa ini juga rentan terhadap eksploitasi seperti misalnya dijadikan objek tontonan serta digunakan sebagai hewan percobaan. Salah satu masalah kesehatan yang sering terjadi pada satwa ini adalah simian tuberculosis, namun laporan penyakit ini pada monyet hasil tangkapan masih sangat sedikit. Tuberkulosis merupakan zoonosis yang dapat merugikan kesehatan manusia dan hewan. Penelitian ini bertujuan mengetahui prevalensi tuberkulosis pada monyet ekor panjang yang ditangkap dalam kurun waktu 10 tahun. Hasil penelitian menunjukkan bahwa prevalensi tuberkulosis adalah 9.0% dan tidak ada perbedaan yang signifikan antara tahun dengan jumlah monyet yang terinfeksi dari tahun 2011 sampai 2014. Kasus tuberkulosis paling banyak terjadi pada tahun 2013 dengan prevalensi sebesar 13.7% dan tidak ada perbedaan yang signifikan antara kondisi hewan dengan jumlah monyet yang terinfeksi. Hasil penelitian dapat disimpulkan bahwa tingkat prevalensi tidak menimbulkan ancaman zoonosis namun satwa ini tetap harus dilindungi dari eksploitasi.

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.
