Judul: Risk factors of hypertension of grade III and IV leadership training participants at Center of Management and Leadership Agricultural Training, Bogor
Abstrak: Prevalence of hypertension in Indonesia is quite high. The severe hypertension will cause serious disease such as coronary heart disease, stroke and kidney failure. The purpose of this study was to assess the risk factors of hypertension which include the inherent factors such a demographic factors and family history and modifiable risk factors such a lifestyle and health status. This study used a case-control study design. The respondents were the participants of grade III and IV leadership training at Center of Management and Leadership Agricultural Training, Bogor. The sample of this study were 96 participants consisting of 48 cases (hypertension) and 48 controls. Analysis of the data was bivariate and multivariate with linier regression. More than three quarters of respondents (80.2%) aged 40 years old and over, where the group of hypertension was 83.3% and group with no hypertension was 77.1%. More than three quarters of the respondents (78.1%) were male, where there is no different proportion between hypertension dan no hypertension group were 77.1% and 79.2%. In term of hypertension family history, the case group with family history of hypertension was 62.5%, more than the control group with family history of hypertension was only 41.7%. Life style, which include eating fatty and salty foods habits, exercise, and smoking habits were also studied. The study refeal that there is no significant different (p <0.05) between the cases and control group in life style. There was no significant (p< 0.05) between the cases and control group in health status which include the nutritional status (BMI) and estrogen contraceptive usage (specific for female respondents), except the presence of stress. The variables which significant (p<0.05) with hypertension were family history of hypertension and presence of stress.

Judul: Faktor Risiko Hipertensi Pada Empat Kabupaten/Kota Dengan Prevalensi Hipertensi Tertinggi Di Jawa Dan Sumatera
Abstrak: Hypertension is a common public health problem that occur both of developed and developing countries. Increasing prevalence of hypertension independently associated with diet and lifestyle. Untreated hypertension leads to many degenerative diseases, including renal disease, congestive heart failure and peripheral vascular disease. Therefore the purpose of this study is to examine factors that can be protective and enhance hypertension prevalence, so that population can save their blood pressure (BP) by preventive and rehabilitative methodes. This study is a cross-sectional analysis in 5 104 subjects aged 18-97 y, consist of 2 491 males and 2 613 females. Data on Body Mass Index (BMI), BP, and other background characteristics of study partisipant were generated using the Riset Kesehatan Dasar (Riskesdas) 2007, at four demographics surveillance sites in Kuantan Singingi and Rokan Hilir (Riau Island), Wonogiri and Salatiga (Central Java). Hypertension was define as SBP≥140 mmHg or DBP≥90 mmHg, with adaptation of the recent JNC-7 definitions. Multiple logistic regression analyses were carried out to determine the odds of hypertension across the whole characteristic, while controlling for possible confounding. A high prevalence of hypertension was noted among four regions population in Kuantan Singingi (48.8%), Rokan Hilir (49.8%), Wonogiri (50.7%) and Salatiga (47.0%). The risk factor which can be reduce hypertension prevalence are ages 40-60 y (OR=0.229) and >60 y (OR=0.501), didn’t do middle physical activity (OR=0.814), didn’t do walking or ride bicycle (OR=0.744), underweight (OR=0.544) and overweight (OR=0.372). While the risk factor which can be enhance hypertension prevalence are education junior and senior high school (OR=1.292) and eating much salty foods (OR=1.258).

Judul: Nanokristalin Pirit (FeS2) sebagai Material Semikonduktor Fotovoltaik.
Abstrak: Teknologi fotovoltaik adalah suatu proses yang dapat mengubah sinar matahari menjadi energi listrik dengan media semikonduktor. Penggunaan sel surya untuk fotovoltaik hanya dapat mengonversi radiasi matahari menjadi energi listrik kurang dari 20%. Efisiensi akan meningkat ketika material semikonduktor untuk fotovoltaik dibuat menjadi ukuran nano. Pirit merupakan salah satu material semikonduktor fotovoltaik yang memiliki energi pita celah (Eg) dalam kisaran 0.8–0.95 eV. Energi pita celah tersebut terbukti meningkat ketika disintesis dengan metode hidrotermal menggunakan beragam molar [S]:[Fe] pada suhu 200 °C dalam 24 jam. Nilai energi pita celah yang dihasilkan adalah 1.58–2.073 eV. Ukuran nanokristalin pirit yang dihasilkan berada pada kisaran 21.04–58.77 nm menurut data Particle Size Analyzer. Besarnya ukuran nanokristal pirit yang tumbuh kurang dari 50 nm merupakan poin penting untuk aplikasi fotovoltaik.
