Judul: Pengaruh Intervensi Minuman Jelly Cincau terhadap Kadar Malondialdehid dan C-Reactive Protein (CRP) pada Pria Perokok Dewasa
Abstrak: Kebiasaan merokok dapat menurunkan status kesehatan, diantaranya ditandai dengan meningkatnya kadar MDA dan CRP tubuh. Pangan fungsional yang mengandung antioksidan seperti jelly cincau merupakan salah satu alternatif untuk menurunkan kadar MDA dan CRP. Tujuan umum penelitian ini adalah menganalisis pengaruh intervensi jelly cincau terhadap kadar MDA dan hs-CRP pada pria perokok dewasa. Desain penelitian ini menggunakan quasi eksperimental dengan pre-post test control. Subjek dibagi menjadi empat kelompok yang terdiri atas 1) Kontrol (K) yang tidak diberikan pangan intervensi apapun; 2) P1 yang diberikan pangan intervensi selama 14 hari; 3) P2 yang diberikan pangan intervensi selama 21 hari; 4) P3 yang diberikan pangan intervensi selama 28 hari. Subjek diminta untuk mengonsumsi jelly cincau 200 gram per hari. Sebelum intervensi, seluruh subjek memiliki kadar MDA diatas normal dan kadar hs-CRP yang normal. Hasil penelitian menunjukkan bahwa kadar MDA subjek pada kelompok perlakuan menurun secara nyata (p<0.05) setelah dilakukan intervensi. Penurunan tertinggi terjadi pada P3 (49,82 %). Hasil uji ANOVA terhadap kadar hs-CRP subjek antar kelompok menunjukkan bahwa tidak terdapat perbedaan yang nyata terhadap kadar hs-crp subjek antar kelompok.

Judul: Pengaruh Intervensi Jelly Cincau Hijau (Premna oblongifolia Merr.) terhadap Profil Lipid Pria Perokok Dewasa
Abstrak: Smoking habit is strongly associated with changes in lipid profile. Functional beverages such as green grass jelly can be used as an alternative to improve lipid profile. The general objective of this study was to analyse the effect of green grass jelly intervention on lipid profile of adult male smokers. This study used an experimental with pre-post test control design. Subjects were divided into four groups, consisting of 1) Control (K) did not received any intervention; 2) P1 received intervention for 14 days; 3) P2 received intervention for 21 days; and 4) P3 received intervention for 28 days. Subjects of the intervention groups were asked to consume 200 grams of green grass jelly per day. The results showed that there was a significant reduction in total cholesterol and LDL cholesterol levels and also a significant increase in HDL cholesterol levels (p<0.05) of subjects in group P1, P2, and P3 after the intervention. The results of ANOVA test on triglyceride levels showed that there was no significant difference in triglyceride levels among subjects of all groups.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
