Abstrak: Penelitian ini bertujuan untuk menganalisis konsumsi pangan, kebiasaan merokok terhadap tekanan darah pada Buruh Tani di Kecamatan Pakuniran Probolinggo. Hasil uji beda Mann-Whitney tidak menunjukkan adanya perbedaan yang signifikan (p>0.05) antara karakteristik subjek, asupan zat gizi, tingkat kecukupan energi, tingkat kecukupan protein, status gizi dan kebiasaan merokok terhadap tekanan darah subjek. Hasil uji kolerasi Spearman menunjukkan tidak terdapat perbedaan yang signifikan (p>0.05) antara pendidikan dan status gizi dengan asupan gizi, Sedangkan antara usia dengan asupan terdapat perbedaan yang sugnifikan (p > 0.05). Hasil uji kolerasi Pearson Hasil uji korelasi Person menunjukkan bahwa tidak terdapat hubungan yang signifikan (p> 0.05) antara status gizi dengan tekanan darah.

Judul: Hubungan antara suhu lingkungan kerja dengan pola konsumsi pangan, status gizi, dan riwayat kesehatan pekerja pandai besi
Abstrak: Tujuan dari penelitian ini adalah untuk menganalisis hubungan antara suhu lingkungan kerja dengan pola konsumsi pangan, status gizi, dan riwayat kesehatan pekerja pandai besi di Desa Hadipolo, Kabupaten Kudus, Jawa Tengah. Desain penelitian yang digunakan adalah cross sectional study dengan jumlah subjek 70 orang. Subjek adalah pekerja pandai besi, berjenis kelamin laki-laki, berumur 19-64 tahun, bersedia diwawancara, dan memiliki masa kerja lebih dari satu tahun. Tempat dan subjek penelitian dipilih secara purposive. Berdasarkan uji korelasi Pearson tidak terdapat hubungan yang signifikan antara suhu lingkungan kerja dengan pola konsumsi pangan dan status gizi pekerja, serta tidak terdapat hubungan yang signifikan antara pola konsumsi pangan dengan status gizi pekerja (p>0.05). Uji korelasi Spearman menunjukkan terdapat hubungan signifikan antara suhu lingkungan kerja dengan keluhan kesehatan (p=0.000, r=0.698) dan tidak terdapat hubungan yang signifikan antara suhu lingkungan kerja dengan frekuensi sakit (p>0.05).

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.
