Judul: Analisis Strategi Komunikasi Pemasaran di Wana Wisata Curug Tujuh Cilember Cisarua Kabupaten Bogor
Abstrak: The government in this case Perhutani realized about business potential of nature tourism and establish natural tourism places (ecotourism). One of ecotourism places that they have is Cilember Seven Waterfalls. This research used quantitative approaches was supported by qualitative approach to determine how the manager/employee doing marketing communications activities and determined the relationship between the design of marketing communications activities messaging, variety of communication media messages, and frequency of delivery of messages to the effectiveness of marketing communications. Correlation test showed that variety of communication media messages had relation with the effectiveness of marketing communications. SWOT analysis calculations showed that the manager/employee should change their strategy in order to use the opportunities. Formulation of marketing communications strategy was created to find strategies that can be developed by ecotourism managers/employee.

Judul: Strategi Pengembangan Penangkaran Kupu-Kupu di Wana Wisata Curug Cilember Cisarua Bogor
Abstrak: Wana Wisata Curug Cilember merupakan salah satu kawasan wisata dengan berbagai objek daya tarik wisata di dalamnya, salah satunya penangkaran kupu-kupu. Penangkaran kupu-kupu ini telah beroperasi selama 15 tahun dan mengalami beberapa perubahan dalam aspek pengelolaannnya. Tujuan dari penelitian ini adalah untuk melihat dinamika pengelolaan, gambaran keberhasilan penangkaran dan menyusun alternatif strategi pengembangan penangkaran. Data hasil observasi, pengukuran, wawancara dan studi pustaka kemudian dianalisis menggunakan analisis SWOT. Dihasilkan alternatif pengembangan yaitu mengoptimalkan peran pemandu wisata, mengembangkan bentuk promosi, pembuatan papan interpretasi, mengembangkan wisata edukasi, mengadakan kerja sama baik dengan lokasi wisata berbasis kupu-kupu lainnya maupun pemerintah Kota dan Kabupaten Bogor, serta mengadakan pengecekan sarana prasarana secara berkala.

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.
