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: Pengaruh Pemberian Minuman Cincau Hijau (Premna oblongifolia Merr.) terhadap Penurunan Tekanan Darah pada Wanita Dewasa Penderita Hipertensi Ringan dan Sedang
Abstrak: This study was aimed to analyze the effect of green grass jelly drink (Premna oblongifolia Merr.) on reducion of blood pressure among adult women suffered from mild and moderate hypertension in Central Bogor Region. There were two intervention formulas, namely Formula A consisted of green grass jelly and brown sugar and Formula B consisted of green grass jelly and non calori brown sugar. Subjects consisted of 25 adult women aged over 45 years old and divided into 5 groups, namely one control and four experimental groups. Formula A was intervented into 2 groups, P1 (received intervention everyday) and P2 (intervention every two days). Formula B had the same pattern with the Formula A (P3 and P4). The result shows that the systolic blood pressure of P1 decreased significantly (p<0.05) by 20-25 mmHg. In addition, the diastolic blood pressure on groups of P1 and P3 decreased significantly (p<0.05) by 14-15 mmHg after the two weeks intervention.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
