Judul: Pengaruh Suplementasi Kapsul Serbuk Daun Torbangun (Coleus Amboinicus Lour) Dan Konsumsi Ikan Secara Rutin Terhadap Tekanan Darah Dan Total Kolesterol
Abstrak: Prevalensi hipertensi dan hiperkolesterolemia di Indonesia saat ini cukup tinggi. Faktor yang mempengaruhi diantaranya aktifitas fisik, status gizi dan konsumsi pangan. Mengonsumsi kapsul serbuk daun Torbangun (Coleus amboinicus Lour) dan ikan secara rutin memungkinkan adanya pendekatan yang lebih komprehensif dalam pengelolaan awal faktor risiko penyakit degeneratif khususnya hipertensi dan hiperkolesterol. Tujuan umum dari penelitian ini adalah untuk mengetahui pengaruh suplementasi kapsul serbuk daun Torbangun (Coleus amboinicus Lour) dan konsumsi ikan secara rutin terhadap tekanan darah dan total kolesterol. Penelitian ini merupakan jenis penelitian kuasi eksperimental. Desain penelitian yang digunakan adalah pre-post test with control design. Subjek penelitian adalah masyarakat kota Kendari yang tergabung dalam lembaga kerukunan masyarakat WAKATOBI provinsi Sulawesi Tenggara. Setelah diseleksi berdasarkan syarat inklusi dan menyetujui Informed Consent diperoleh 32 orang subjek berpartisipasi dalam penelitian ini dan selanjutnya dibagi menjadi 2 kelompok (16 perlakuan kapsul serbuk daun Torbangun dan 16 kontrol). Data karakteristik subjek, pola konsumsi pangan, tekanan darah dan total kolesterol subjek disajikan secara deskriptif. Pengaruh konsumsi ikan dan kapsul serbuk daun Torbangun pada kelompok perlakuan dan kelompok kontrol terhadap angka tekanan darah dan total kolesterol dianalisa dengan menggunakan uji t. Sebagian besar subjek penelitian memiliki status gizi gemuk, berumur 30 - 60 tahun, berprofesi sebagai dosen dengan latar belakang sarjana serta berasal dari daerah Sulawesi. Hasil penelitian di empat titik pengukuran (H0, H14, H22, H35) menunjukkan bahwa pada awal penelitian tekanan darah sistol, diastol, maupun total kolesterol subjek kelompok perlakuan tidak berbeda nyata (P>0.05) dengan kelompok kontrol. Demikian pula yang terjadi pada hari ke empat belas. Pada hari ke 22 penelitian, tekanan darah sistol subjek kelompok perlakuan berbeda nyata (P<0.05) dengan kelompok kontrol sedangkan tekanan darah diastol dan total kolesterolnya tidak berbeda nyata. Pada hari ke 35 penelitian, tekanan darah sistol dan diastol subjek kelompok perlakuan berbeda nyata dengan kelompok kontrol sedangkan total kolesterolnya tidak berbeda nyata.

Judul: Correlation of Torbangun Leaves (Coleus amboinicus Lour) Powder Capsules Suplementation on Blood Pressure and Cholesterol Total
Abstrak: The aim of this study was to determine the effect of torbangun leaves (Coleus amboinicus Lour) consumption in maintaining blood pressure and total cholesterol level. The leaves were prepared as simplicia capsules and were given as supplement. The study used pre-post test design and was conducted in May to June 2011 at settlements area around IPB Baranang Siang campus in Bogor. The study participants were 52 IPB extension program students, men and women aged >18 years old for middle-age to elderly. The study result showed that most subjects had normal nutritional status (78,8%) and had low level of physical activities (84,6%). Developmental changes in blood pressure values in the treatment group and control had increased or decreased at any point of observation in both systole and diastole pressures. However the changes in the systole and diastole in both the groups did not exceed 20/10 mmHg. Changes in total cholesterol values were also influenced by the type of intervention and gender. The average changes in cholesterol values increased by 10 mg/dl in men and 7 mg/dl in women. T test results on blood pressure values of study participants at the beginning and at the end of the study did not showed significant differences between the treatment and the control groups (P>0,05). But total cholesterol values and changes in total cholesterol values of study participants at the beginning and at the end of the study showed significant differences between the treatment and the control groups (P<0,05). So there was a change in the control group value at the end of the observation cholesterol with an average change in the value of cholesterol as much as 8,35 ± 11,9 mg/dl.

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.
